Passive:Dynamic Simulation

2014-05-30T18:18:14Z

LisaWhite:

== Switch to dynamic Mode ==
The major advantage of WUFI®Passive is the possiblity to compare the results of the static passive house calculation method with the dynamic simulation of WUFI®Plus.
 Please note that the simulation of WUFI®Plus requires additional input data, especially for materials, which require data like heat storage capacity and hygrothermal properties.
=== Set Boundary Conditions from Passive House ===
[[Bild:Passive-new_button.png|right|thumb|The new button can be found here]]
Certain input parameters can be carried over from WUFI®Passive to WUFI®Plus mode. To simplify this step new a button "Set Boundary Conditions from Passive House" has been introduced. This option will set reasonable values for the dynamic simulation mode for better comparison of the results.
[[Bild:BoundaryConditionsPassivehouse.png|left]]
 
 
 Setpoints for WUFI®Plus in detail:
 '''Temperature:''' Design Minimal Temperature = indoor temperature, Design Maximal Temperature = overheating temperature,
 '''Ground temperature:''' New optional ground climate added with Relative Humidity = 99 constant, Temperature = sin curve with min/max values and phase shift from WUFI®Passive calculation
 '''Internal loads:''' A constant internal load is added depending on the internal heat gains of the passive house calculation
 '''Internal loads:''' A constant moisture load is added depending on the humidity source entry of the passive house calculation
 '''Relative Humidity:''' Design Maximal Relative Humidity = Max Humidity Ratio Dehumidification set in passive house verification mode
 '''Mechanical Ventilation:''' Mechanical Ventilation = Average Air Change Rate Mechanical Ventilation. If there is an additional summer ventilation in passive mode, a separate profile for the summer months is created including the additional ventilation.
 '''Natural Ventilation:''' Same as Mech. Ventilation. Infiltration is taken into account.
 '''HVAC System:''' The maximum device capacity is taken over.

Passive:Sketch-Up

2014-05-30T17:13:53Z

LisaWhite:

Sketch-Up can be used to import a building into WUFI®Plus or WUFI®Passive. Instead of defining the building in WUFI itself, you can build it in Sketch-Up, define the components, and create and attach multiple zones.

== Installation ==
[[Bild:Wufi-sketchup_install.png|right|Sketchup]]
The installation of the Sketch-Up plug-in is quite easy. Open the WUFI Sketch-Up plug in via the options menu on the toolbar, check the box for "Use WUFI plugin into Sketchup" and search for the path of the Sketch-Up installation. Click "Install" and the installation is complete.

== Usage ==
[http://www.wufi-wiki.com/wufifilme/flash/Sketch_up.swf This video] gives a good explanation on how to use the plug in. 
Zones can be generated by clicking on the "Plug-ins" button in the toolbar, selecting WUFIplus, and clicking on "Zones". A window will open, where you can define the number of zones in your building. 

You can define your building by outer OR inner dimensions. Be sure to check if WUFI@Passive is set to the corresponding adjustment. If inner dimensions are set, WUFI will add the walls on the outer side of the model and vise versa.

Passive:Wufi Passive

2014-05-30T17:01:28Z

LisaWhite:

WUFI®Passive was developed by the Fraunhofer-Institute of Building Physics (IBP) and the Passive House Institute US (PHIUS) by combining the WUFI®Plus building simulation tool with a Passive House Verification feature to meet the needs of Passive House communities worldwide.
 
 
In times of decreasing fossil fuel resources, Passive Houses have shown to be an important step towards more efficiency and less energy consumption in the building sector. By using dynamic models and hourly data, WUFI®Passive has an edge against other verification tools, and the integrated WUFI®Plus tool also has the ability of hygrothermal analysis and calculations. 
The Passive House Verification in WUFI®Passive calculates the energy demand of buildings on monthly or annual basis. Thereby transmission, ventilation, radiation and inner loads are considered. The energy gains and losses are balanced and a detailed input (heating, ventilation, HVAC etc) allows the calculation of the total energy demand. Depending on the energy sources used, the primary energy consumption is determined as well. 
 
'''NOTE:''' 
Some links on the WUFI®Passive pages lead to WUFI®Plus pages, as there are no changes in the respective pages.

This page shows the different sections of the Passive House Verification output report. There will be a short description of the output parameters for each section as well as a screenshot.
== Building Information ==
[[Bild:Passive-verification_building.png|right|thumb|Building information]]
The first section summarizes general information about the building itself and important boundary conditions such as the interior temperature and the internal loads.
 

== Passivehouse requirements ==
[[Bild:Passive-verification_requirements.png|right|thumb|Passivehouse requirements]]
The primary passive house requirements depend mostly on energy demand, mainly in form of cooling and heating as well as primary energy demand. All values are given in a specific value (per square meter/feet) and in total. Heating and cooling demand also provide a peak value(month), which is estimated by the extreme weather conditions in the climate tab. 

== Secondary Passivehouse Requirements ==
[[Bild:Passive-verification_secondary.png|right|thumb|Secondary requirements]]
The secondary requirements consist of the HRV efficiency and a percentage chance of overheating of the building. Depending on the likelihood of overheating, WUFI®Passive will give recommendation if a separate cooling system is needed or not. 

== Building Elements ==
[[Bild:Passive-verification_buildingelements.png|right|thumb|Building elements]]
The building elements describes the influences of windows, HVAC systems and electric devices on the energy demand. 
=== Windows ===
The graphic shows the heat losses and gains of solar radiation through windows separated by orientation. Also average U-values for all windows are given as well as the total glazing area.

=== HVAC ===
The energy demand of all HVAC devices is summarized here.

=== Electricity ===
The energy demand of all other electric devices is listed here. 

== Heat Flow ==
[[Bild:Passive-verification_heat_flow.png|right|thumb|Heat flow]]
Heat gains and losses are divided into different categories. 
Heat gains are separated into solar gains, [[Passive2:Inner_Loads|inner sources]], thermal bridges and mechanical heating. 
Heat losses are separated into windows & doors, the opaque building envelope, natural ventilation and mechanical ventilation. 
Both statistics are displayed in a pie chart. 

== Climate ==
[[Bild:Passive-verification_climate.png|right|thumb|Climate]]
Here you find local climate conditions e.g. the height of the building and ground conditions. 
Furthermore there is a graphical overview of the climate given in the [[Passive2:Dialog_Climate|localization/climate]] section and possible calculations of undefined values (e.g. ground/sky temperatures). 
The second graph displays the solar radiation separated by orientation. 

== Calculation Parameters ==
[[Bild:Passive-verification_calculation_parameters.png|right|thumb|Calculation parameters]]
The main boundary conditions for the heat loss calculation are listed here. 
Here you will also find the extreme weather conditions for the calculation of the heating/cooling load. For the heating load there are two possible climates available. The relevant climate (the climate with higher calculated heating load) is displayed on bottom.
 

== Annual Heat/Cooling Demand ==
[[Bild:Passive-verification_heatcooling_demand.png|right|thumb|Heat/Cooling demand]]
This displays the balance between annual heat gains and losses and thereby calculates the annual heat/cooling demand. 
The losses/gains are summarized by categories and their balance is graphically displayed on the bottom. 
Note: the heat gains during heating period and the heat losses during the cooling period are reduced by the Utilization Factor. The Utilization Factor is estimated by a complex calculation.
 

== Heating/Cooling Load ==
[[Bild:Passive-verification_heatcooling_load.png|right|thumb|Heat/Cooling load]]
Apart from the Utilization Factor, the calculation is similar to the heating/cooling demand calculation. The results are based on the extreme weather conditions shown above. For the heating load, two possible weather conditions are investigated and the worst case is taken.

Passive:Status and Results

2014-05-29T21:56:04Z

LisaWhite:

== The Status and Result Box ==
The Status and Result Box displays the status of the input e.g. if data is missing or unrealistic. If all information is given, a small portion of the results are displayed.
 
It can be minimized by clicking the grey X-button. This can be useful e.g. when reading the [[Passive:Results|Results]]. The button then changes to a green arrow and by clicking the arrow the box will reappear.
=== Error Message ===

[[Bild:Passive-resultbox_error.png|left]]
As long as there is still input data missing, the status and results box shows error messages. Double clicking on it makes WUFI®Passive jump to the cause of the error.
The error messages are constructed according to the structure of the Navigation Tree, so navigating to the cause is just a matter of tracing the error message line by line in the Navigation Tree.
 

=== Warnings/comments ===
WUFI®Passive has a new feature; if some data is unlikely or unrealistic, the status button will turn yellow and a new button will appear.[[Bild:Passive-result_warningscomments.png]] 
By clicking it, WUFI will tell you which values are unrealistic or uncommon. 
[[Bild:Passive-result_warningscommentsbox.png]]

=== Result ===
Unlike [[Plus2:Status_and_Results#Starting_the_calculation|WUFI®Plus]], WUFI®Passive will give out results without any calculation time. As soon as all needed information is given, WUFI will return a small portion of data in this window:
[[Bild:Passive-resultbox_result.png]] 
The thicker black lines in the middle of the graph show the cutoff criteria for the Passive House. Alternatively the green check and the red "x" on the right side also display if the criteria are fulfilled or not.

 
You can find the detailed information about the results [[Passive:Results|here]].

Passive:First Steps

2014-05-29T21:30:52Z

LisaWhite:

'''Example Case''' 
This example will give you an easy step by step guide on how to input a new case in WUFI®Passive. It will be a very easy case and is inspired by [http://www.wufi-wiki.com/wufifilme/flash/introduction.swf the introduction movie]. For more advanced stuff, go to the [[Passive:Input|advanced example]].

== Step Zero: Case 1 ==
In contrast to WUFI®Plus, this section does not contain any essential data but you can name your project and add some remarks.
[[Bild:Passive-example_case1.png|Figure 1: Case 1|center|frame|Figure 1: Case 1]]

== Step One: Climate and Localization ==
[[Bild:Passive-example_climate.png|Figure 2: Climate|right|thumb|Figure 2: Climate]]
WUFI Passive's standard climate is the German reference climate as in DIN 4108-6 but we will use a different climate, in our case it will be from Hannover. To input a new climate dataset select the "user defined" scope and press the browse button. After you input valid data, the climate tab will display [[Passive2:Dialog_Climate#Climate|information]] for temperature and radiation.
Remember that WUFI®Passive needs a special format of climate files which you can see in the previous link or in this [http://www.wufi-wiki.com/wufifilme/flash/climate_data_input.swf movie]. 
 

== Step Two: Building geometry ==
There are 3 ways to define a building in WUFI®Passive, the easiest one being the [[Plus_2.X:Building#Building_Wizard|building wizard]] for very simple buildings or spaces. The other two ways are [[Plus_2.X:Building#Edit_3D|vertices]] and [[Passive:Sketch-Up|Sketchup]], which work way better if you want to build a more complex building. 
For our example we will use a simple room with an unheated attic and a slab on grade.
[[Bild:Passive-example building.png|center|1000px|Building wizard and orientation]]
We will add 4 windows on the south facade using the visualization box in the bottom left corner. Click the orange boxed "Windows/openings" button and a new page will appear. Click the green boxed button "Edit List" and insert the windows as seen in the picture.
[[Bild:Passive-example_windows.png|center|1000px|How to input windows]]
Be aware that the coordinate system of the chosen wall starts in the bottom left and the X’ – axis is the orientation of the window in horizontal direction and the Y’ – axis in vertical direction. 
There is also a [http://www.wufi-wiki.com/wufifilme/flash/window_input_21.swf movie] about this topic. 
A door in the north wall can be implemented almost the same way. Turn the building in the visualization box, create a "window" just like before and afterwards right click the new element and change its properties to opaque.
[[Bild:Passive-example_door.png|1000px|center|Implementation of the exterior door]]
To clarify this is an exterior door, click on "Component 5" in the tree (if you are looking at the door in the visualization box, it will be red edged) and make a check on the "exterior door" option.

== Step Three: Options for the passive house ==
Next click on the "PH case:" section on the tree. Per default its value is "residential" and we will not change anything in the "General" tab here. Instead we will go to "Additional data" and input the values boxed in blue in the picture.
[[Bild:Passive-example ph case.png|center|frame|Only two values are needed here]]
Other than that we will not change any standard values. We will proceed to the next section: "Foundation interface" where we will fill in additional values.
[[Bild:Passive-example_foundation.png|center|frame|Again only two values]]

== Step Four: Zonal data ==
In this section we will define the [http://www.wufi-wiki.com/wufifilme/flash/tfa_example.swf TFA] and the gross volume of our building. In the green box we define the specific heat capacity of our wall; in this case our wall is massive.
[[Bild:Passive-example_zone1.png|center|frame|Zonal values]]

== Step Five: Defining the components ==
[[Bild:Passive-example_name.png|thumb|right|Naming the visualized components]]
The next subsection is all about the components and their assemblies. First we click on "Visualized components" and name each component. 
Then we define the assemblies of all components and we will start with the exterior wall as described in [http://www.wufi-wiki.com/wufifilme/flash/def_opaque_component.swf this movie]. 
Therefor we click on "Component 3:ext. wall" and then on the subsection "assembly" and then on the red circled "Edit" button.
[[Bild:Passive-example_assembly.png|center|1000px|First steps to a new assembly]]
 
A new window will pop-up, where you can define the assembly. As seen in the video, we will construct a rear wall with wooden beams in it.
First we will name our assembly and then search for our needed materials by clicking on "New".
[[Bild:Passive-example_ext_wall.png|center|1000px|Starting the construction of the assembly]]
In the material database we will chose the "Wooden materials;Boards" section and define the first layer of our wall.
[[Bild:Passive-example_first_layer.png|center|1000px|The first layer]]
[[Bild:Passive-example_subdivisions_add.png|right|thumb|The add button]]
The next layer then will be an insulation material. In this layer are the interupting beams, so click on the "Add" button and you will get to the material database again. Select your beam material (in this case it is "Spruce, radial", which you can find in the "Wooden materials;Boards" section) and then the raster of the timber beams by creating new sections in the horizontal section. Then click on the spruce in the "exchange materials" box and click on the respective section as seen in the picture below.
[[Bild:Passive-example_wooden_beam.png|center|1000px|The raster in the second layer of the wall]]
Define then the remaining layers so that the assembly consists of following materials:[[Bild:Passive-example_ext_wall_assembly.png|thumb|Assembly of the exterior wall|right]]

{|
|''' Material'''
| '''λ [W/mK] '''
| '''Thickness [m]'''

|+
| ''AGEPAN DWD protect
| ''0,082
| ''0,016
|-
| ''Mineral Wool (heat cond.: 0,04 W/mK)

|-
| Oriented Strand Board (density 615 kg/m³)
| 0,13
| 0,015
|-
| Gypsum Board
| 0,2
| 0,01
|}
 
In the second layer of mineral wool more wooden beams are inserted. This time add three horizontal divisions with the dimensions 0,03 , 0,37 and 0,03. Fill in the spruce in both small gaps. 
Back in the WUFI window, you have to assign the assembly to the respective component. The assign button is right beneath the edit button we used before. 
You can also use predefined or save your own assemblies [[Passive:Menu_and_Dialogues#Database:|here]] or by clicking the "Select from database" button right next to the "Edit" button we used earlier. This comes in handy if you want to use the same assembly at different projects. 
Now it is time to define the other components as well;

<div class="tleft" style="clear:none">[[Bild:Passive-example_bottom_plate.png|thumb|Bottom plate|center]]</div>
<div class="tleft" style="clear:none">[[Bild:Passive-example_exterior_door.png|thumb|Exterior door|right]]</div>
 

=== Windows ===
For this example, a predefined window is used. More about implementing windows and their settings can be seen in [http://www.wufi-wiki.com/wufifilme/flash/window_input_21.swf this video].
[[Bild:Passive-example_window_settings.png|1000px|center|How to get to the window settings]] 
The example 2 windows are predefined windows from the WUFI®Passive database and easy to find.

== Step Six: Interior Walls ==
In this simple building, there is only one interior wall. Click on the "Not visualized components" part of the tree and input the data as seen in the picture below.
[[Bild:Passive-example_notvis_components.png|1000px|center|Not visualized components]] 
For advanced users: It is also possible to change its orientation and inclination as well as the attached zones. If doing the latter, this component has to be defined the same way as the visualized components.

== Step Seven: Inner Loads ==
[[Bild:Passive-example_inner_loads.png|right|thumb|Inner loads with respective values]]
The next step is the implementation of inner loads. Click on the "Inner Loads/Occupancy" section in the tree and add the following appliances with its data into the list:
{|
| '''Appliance ''' || '''Quantity ''' || '''Energy demand[kWh/use] or [kWh/day] '''|| ''' Additional Info '''
|-
| Kitchen - dishwasher || 1 || 1,1 || DHW connection
|-
| Kitchen - fridge/freeze combo || 1 || 1,2 || -
|-
| Kitchen - cooktop || 1 || 0,3 || Cooking with electricity
|-
| Laundry - Washer || 1 || 1,1 || DHW connection
|-
| Laundry - Dryer || 1 || 3,5 || Remaining Dampness: 40 / Clothesline
|}
WUFI also has a standard dataset with different settings as well as the possibility to input completely different appliances with a "user defined" option.
 

==Step Eight: Implementing the ventilation ==
In this section different utilization patterns may be set up to assign to each room. In this case only one pattern will be defined and then used on every room. Click on the "New" button and then input the ventilation pattern as seen on the picture.
[[Bild:Passive-example_ventilatiopn.png|center|Adding a new ventilation pattern]]
To apply this pattern to each room, click on the "Rooms ventilation" tab and then add four rooms: one kitchen, bathroom, shower and WC by pressing the "New" button on the right and then choosing the respective scope in the "Room type" section or just click on the "Standard dataset" button (boxed green). Then chose the desired pattern for each room in the "Utilization pattern" section of the table, in this case "Pattern 1: Example pattern". 
Each room has a predefined value of exhaust air of the design volume flow rate, which you are free to change if necessary, but for this case use the predefined ones and set the same values on the supply air, as seen in the red box.
[[Bild:Passive-example_ventilation_distribution.png|center|1000px|Distribution of the ventilation]]
Each room also has its own "Additional data" section where the area of the room and its clear room height may be added. For this example, use the values as seen in the table below:
{|
| || '''Kitchen ''' || '''Bathroom ''' || '''Shower ''' || ''' WC '''
|-
| '''Area [m²] ''' || 20 || 12|| 7 || 6
|-
| '''Clear room height[m] '''|| 2,5 || 2,5 || 2,5 || 2,5
|}
The last step regarding ventilation will be to add mechanical ventilation during summer. Therefore, click on the "Summer ventilation" tab and input a 0,3 ACH as seen in the picture.
[[Bild:Passive-example_summer_ventilation.png|center|1000px|Settings for summer ventilation]]

== Step Nine: Thermal Bridges ==
Thermal brigdes have an underestimated influence on energy performance and are found in every building. In our example building there is only one so add it by clicking on the "Thermal bridges" section in the tree and then on the "New" button on the right side. The thermal bridge has a linear thermal transmittance of 0,04 W/mK and is 42 meters long. 
[[Bild:Passive-example_thermal_bridge.png|center|1000px| Implementation of thermal bridges]]

== Step Ten: Connection with the unheated attic ==
For simplicity of this example, the attic is unheated and non-vented but does have a temperature difference reduction factor of 75%.
[[Bild:Passive-example_unheated_attic.png|center|Changing the heat reduction factor of the unheated attic]]

== Step Eleven: Adding the HVAC systems ==
[[Bild:Passive-example_HVAC_user_defined.png|right|thumb|Choosing a predefined system or define your own]]

The last thing to add is the HVAC system. WUFI®Passive allows multiple systems with different devices and also has two predefined systems, one for ventilation and one for DHW supply. In this example a user defined systems with one heat pump and one mechanical ventilation unit will be defined. The heat pump will be used for space heating and the DHW. 
[[Bild:Passive-example_hvac_general.png|left|thumb|Two devices]] 
Next up are the settings for the heating, DHW and ventilation distribution. For both hydronic heating and the DHW the required information lie in the data of its distribution pipes. Length, design flow temperature and possible heat losses need to be defined for the pipes. The screenshots of the hydronic heating on the DHW show the required data as well as the values used in this example.
<div class="tleft" style="clear:none">[[Bild:Passive-example_hvac_hydrheating.png|thumb|Hydronic heating settings]]</div>
<div class="tleft" style="clear:none">[[Bild:Passive-example_hvac_dhw.png|thumb|DHW]]</div>
[[Bild:Passive-example_hvac_ventilation.png|thumb|right|Ventilation]]
The ventilation tab differs between exhaust and supply ducts and they both have to be defined manually. To do this press the "New" button twice and define one exhaust and one supply duct. The duct shape of both is "Round" and the supply duct length is one meter while the exhaust duct length is 3 meters. Both ducts then have to be assigned to a ventilation unit, in this case assign the "example ventilation". Next, define the duct width, insulation thickness and thermal conductivity (160,60,0,04 for both).

 
== Step Twelve: Getting within the passive house requirements ==
After performing the last steps, WUFI®Passive should give out results. Unfortunately these results will be unsatisfying regarding the heating demand and and the heating load.
[[Bild:Passive-example_unsatisfying.png|center|This is not what we were looking for...]]
 
To solve this problem we will use a different assembly for our exterior wall:
{|
|'''Material''' || '''λ[W/mK]''' || '''Thickness[m]'''
|-
|Cement Line Plaster(stucco,A-value:2,0/m2h0.5)|| 0,8 || 0,02
|-
|EPS(heat cond.: 0.04 W/mK - density: 15kg/m³) || 0,04 || 0,4
|-
|Concrete, w/c=0,05 || 1,6 || 0,15
|-
|Interior Plaster (Gypsum Plaster) || 0,1 || 0,015
|}
And voilá:
[[Bild:Passive-example_conform.png|center|Within the guidelines]]

Passive2:Dialog Climate

2014-05-29T17:46:19Z

LisaWhite:

Unlike WUFI®Plus, WUFI®Passive uses monthly climate data rather than hourly data.

== Localization ==
[[Bild:Passive-case1_localization.png|right|thumb|Localization]]
The climate file is chosen in the localization tab. WUFI's predefined climate is a reference year of Germany and can be altered by using the "user defined" tab in the scope and by browsing the desired climate file. 
Due to WUFI®Passive not using hourly data, different climate files and formations are needed. So far WUFI can read .txt and .xls files as seen in the screens below and in [http://www.wufi-wiki.com/wufifilme/flash/climate_data_input.swf this movie]. To obtain these files/formation you can use meteonorm. 

<div class="tleft" style="clear:none">[[Bild:Passive-case_1_passivebsptxt.png|thumb|Example .txt]]</div>
<div class="tleft" style="clear:none">[[Bild:Passive-case_1_passivebspexcl.png|thumb|Example .xls]]</div>
 

== Climate ==
The climate tab summarizes temperature and radiation data in a table and a graph. The picture on the right can be used as a reference for the description.
[[Bild:Passive-case1_climate.png|thumb|right|Climate]]
=== Temperature ===
The upper table shows the monthly mean ambient temperature and, if given in the climate file, the sky, ground and dew point temperature, though they are not necessary for the calculation. The extreme weather condition on the right end are needed to calculate the heating and cooling loads of the building.
=== Solar radiation ===
The lower section contains the mean monthly solar irradiation, separated into the four cardinal points and also the extreme weather conditions.

== Primary energy/CO2-factor ==
[[Bild:Passive-case1_primaryenergy.png|right|Primary Energy]]
In this tab, you can see and set the primary energy factor (PEF) and the CO2-emission factor (CO2EF). 
The PEF is multiplied by the energy demand and varies depending on the chosen material, because the PEF is influenced by both the production process and the transportation of the energy source. 
The CO2EF converts the energy demand into an equivalent amount of CO2. These two factors are important when looking into the sustainability of the passive building. 
[[Bild:Passive-case1 energy scope.png]] 
Though differences are minor, WUFI knows 3 different standards regarding the values of this table. If you have different values, you can create your own table in the "user defined" section.

Passive2:Inner Loads

2014-05-28T22:14:54Z

LisaWhite:

Depending on which building type is chosen, this section offers different input options. If a residential building is simulated in WUFI, only common household appliances and lighting need to be defined. 
For non-residential buildings, the occupancy as well as kitchen and office appliances need to be defined and attached to a utilization pattern.
== Residential building ==
[[Bild:Passive-innerloads.png|Inner Loads|right|thumb]] 
In this section electric devices and humidity sources are defined. They are important to estimate the energy and water demand as well as the humidity load inside the building. In the device scope, WUFI offers a lot of common household devices (dishwater, etc.) as well as the option to implement a different device.
[[Bild:Passive-innerloads_scope.png|Device scope|right]] 
For each device, the quantity and the energy demand are needed. Additional data is needed for some devices: E.g. the dishwasher can be connected with the DHW or cold water. 
If the inner sources of the building are not known yet, WUFI contains a standard set of devices in a common household which can be used by clicking on "standard dataset".
 

== Non-residential building ==
=== Utilization pattern ===
[[Bild:Passive-innerloads_nonres_utipattern.png|thumb|right|Utilization pattern]]
The mandatory data for utilization patterns is given in the columns of the table. The additional data is useful, depending on where the pattern is attached.
 
=== Occupancy ===
[[Bild:Passive-innerloads_nonres_occupancy.png|right|thumb|Occupancy]]
Here the number of occupants of the building is defined as well as humidity sources. When it comes to the activity of the occupants, WUFI can differ between children, sitting adults and standing adults. It is also possible to define the pattern for these people as well the quantity of people following this pattern. 
The additional data section contains a value about additional heat losses through evaporation and toilet usage/settings. 
If the simulated building is a school, WUFI has default values for it.
 

=== Office equipment ===
[[Bild:Passive-innerloads_nonres_offequipment.png|thumb|right|Office equipment]]
Any office equipment can be enumerated here. WUFI itself knows the following devices: PC, monitor, copier, printer, server and the telephone system. If different devices are needed, they can be inserted in the "user defined" scope. "User defined" devices can not be attached to a utilization pattern, therefore the utilization hours/year have to be given. 
The printer and copier also have an additional data section. The hours of utilization in energy saving mode in hours/year can be defined, but are optional.
 

=== Kitchen equipment ===
[[Bild:Passive-innerloads_nonres_kitchequipment.png|thumb|right|Kitchen equipment]]
Kitchen appliances can be defined here. WUFI provides the options cooktop, dishwasher and refrigerator. Use the "user defined" scope if different appliances are needed.
 

=== Lighting ===
[[Bild:Passive-innerloads_nonres_lighting.png|thumb|right|Lighting]]
The required lighting is estimated depending on the amount of daylighting. Therefore data on room geometry, glass transparency and occupancy (utilization pattern) is needed.

Passive:Overview on the User Interface

2014-05-27T22:07:55Z

LisaWhite:

== The User Interface in WUFI®Passive ==
* the [[Passive:Menu and Dialogues|'''Menu and Tool Bar''']] helps you navigate to any function.

* the [[Passive:Tree|'''Navigation Tree''']]: is comprised of branches which pull up different entry screens. It is reasonable to follow its structure while inputting data to make sure nothing is left out.

* the [[Passive:Visualization Box|'''Visualization Box''']] is where the building can be seen and edited.

* the [[Passive:Status and Results|'''Status and Results Box''']] displays errors which need to be corrected, missing inputs, and displays the calculated results when all important data is input.

* the '''Input and Output Dialog Box '''shows the different screens according to the selected entry in the Navigation Tree.
 
[[Bild:Passive_user_interface.png]]

Passive:Dialog Database HVAC

2014-05-22T22:10:19Z

LisaWhite:

[[Bild:Passive-hvac_database.png]]

This window shows the HVAC devices in the HVAC database. You can add and edit your own devices, but you cannot edit the predefined devices. 
For each device an example is given in the database.[[Bild:Passive-HVAC_scope.png|right]]
The scope on the top left corner contains 3 Topics: "All", "Protected Data" and "User defined". 
Under "User defined" a new button will appear which enables you to create new, or delete old, catalogs in the tree. 
 
This window also gives you a short summary of the respective devices in the grey box on the right side of the window. It can be enlarged by changing the borders of the 3 parts of the window or enlarging the window itself. 
Any other functions of this dialog will be explained [[Passive:Dialog Database HVAC new|here]].

Passive:Dialog Case

2014-05-22T22:02:26Z

LisaWhite:

Various cases can be created and defined within one project by right-clicking on "Case 1" in the Navigation Tree Box and then confirming by clicking on "New/Copy Case". This could for example be useful for varying only one parameter of a calculation to get comparable results.
===General===
Here you can name your project and add additional remarks. This information is optional and is strictly informative.
===Report: Data & Results===

Passive2:Visualized Components

2014-05-22T21:58:14Z

LisaWhite:

[[Bild:Passive-viscomp.png]]

All components of the building that require a definition of structure, material or environment are listed under "Visualized Components" and need to be edited here. Clicking on the respective component in the entry table or the in the navigation tree opens the component. In the input window the component’s properties are defined. There are three possible types:

* Opaque components (walls)
* Transparent components (windows)
* Openings (not relevant)

Each type requires different input data. There are also some differences for opaque components, depending on whether or not their surface is in contact with outer air.

== Opaque ==

=== General ===
[[Bild:Passive-viscomp_opaque_general.png|right|Opaque General]]
The first part in the general tab is always the same and unaffected by the type of component chosen. The first line defines whether the component is [[Passive2:Visualized Components#Opqaue|opaque]],[[Passive2:Visualized Components#Transparent|transparent]] or [[Passive2:Visualized Components#Open|open]]. The next two lines define the climates on each side of the component. To check which side is outer and which is inner side, see this [[movie|movie]]. In this example picture, an exterior wall is shown. Thus the inner side is defined as [[Passive2:Zone 1|zone 1, the simulated zone]] and on the outside, outer air, which is the climate for the chosen project location. 
 
The data and the parameter section summarize and calculate some of the input data such as the area, inclination, orientation and the thermal characteristic values of the component.
 

=== Assembly ===
The assembly tab works very much like the one in WUFI®Plus, so for further info, you can go to the respective subpoint of visualized components of [[Plus_2.X:Visualized_Components#Assembly|WUFI®Plus]] or to the [[Plus:Dialog_DatabaseAssemblies|assembly database]].

=== Surface ===
[[Bild:Passive-viscomp_opaque_surface.png|right|Opaque surface]]
The surface type usually only consists of the "Heat transfer resistance" section, but if the chosen assembly has contact with the outer climate, the second section appears. 
In the first section, Rse and Rsi values can be either defined by WUFI by selecting the "According to component type" scope or user defined by choosing the respective scope.
==== Exterior walls/doors ====
When the chosen assembly is in contact to the outer air, the "Solar absorption/emission" section appears. Here the short wave absorption and the long-wave emission of the exterior component can be defined. WUFI also has a selection of different materials with predefined values. You can find them by clicking on the scope. 
The shading reduction factor indicates how much solar radiation is blocked by shading objects. An entry of 1 means 100% of the solar radiation hits the component whereas 0 means total shading. If your exterior wall has different shading factors depending on the orientation, it is advisable to divide the exterior wall into different components so you're able to define the factor to each wall individually.
 

== Transparent ==

=== General ===
The transparent general tab only differs from the opaque general tab in two points. The parameters section contains only one value, the Uw value of the window. Beneath, there are construction Psi-values for each side of the frame. These values can either be defined by window parameters or defined by user by removing the tick. 
Note: For different installation conditions you can modify the Psi-value tab and still use the same database entry. Setting the Psi-value to 0 means no frame-wall connection on this side.

=== Window parameters ===
This section does not differ a lot from WUFI®Plus. Here is a link to the respective [[Plus_2.X:Visualized_Components#Window_Parameters|section]] of visualized components of WUFI®Plus and a link to the WUFI®Plus window [[Plus:Dialog_DatabaseWindows|database]].
=== Solar Protection ===
This tab contains all information about obstructions or devices that reduce the radiation on the windows.
==== General ====
[[Bild:Passive-viscomp_trans_solprot_general.png|right|Solar Proection General]]
The parameters in this section are dependent on solar obstructions and the way the windows are installed in the wall. Also additional shading effects and a special summer shading effect can be implemented.

==== Sunscreen device ====
Additional shading effects caused by a sunscreen device can be input here.
==== Window overhang ====
A window overhang can be implemented here. Use the dimensions of the overhang which affects the window most. 
Note: If no overhang is specified, the dimensions of the reveal are automatically taken as the overhang.
 

== Open ==
Creates an open hole. Has a different influence on the building than transparent components.

Passive2:Ventilation

2014-05-22T20:24:01Z

LisaWhite:

== Utilization pattern ==
[[Bild:Passive-ventilation_utpattern.png|right|Utilization pattern|thumb]]
This section defines the utilization pattern of the ventilation system. If you have different patterns for different rooms, this is the place to create them. They get assigned to the different rooms in the "rooms ventilation" tab. 
Additionally it is possible to define a daily operation schedule with different air flow rates and associated running hours.
 

== Rooms ventilation ==
[[Bild:Passive-ventilation_roomsvent.png|Room ventilation|thumb]]
In this tab all ventilated rooms are assigned a utilization pattern. You can define all rooms or use the standard dataset in WUFI, which contains each one kitchen, bathroom, shower and a restroom. 
The design volume flow rate of supply and exhaust air needs to be given for each room. WUFI will then calculate an average volume flow rate depending on the given utilization pattern and its operation schedule. 
For each room you can input the area and the room height in the "additional data" section to enable WUFI to calculate the average air change rate of the room.
 

== Summer ventilation ==
[[Bild:Passive-ventilation_summervent.png|right|Summer ventilation|thumb]]
In this section you can specify the ventilation situation during the cooling period. For the natural ventilation (both, day and night) there is an additional tool available below. The estimated value from this tool can be applied by clicking "Set value from calculator".

Passive2:Inner Loads

2014-05-19T22:19:04Z

LisaWhite:

Depending on which building type is chosen, this section offers different input options. If a residential building is simulated in WUFI, only common household appliances and lighting need to be defined. 
For non-residential buildings, the occupancy as well as kitchen and office appliances need to be defined and attached to a utilization pattern.
== Residential building ==
[[Bild:Passive-innerloads.png|Inner Loads|right|thumb]] 
In this section electric devices and humidity sources are defined. They are important to estimate the energy and water demand as well as the humidity load inside the building. In the device scope, WUFI offers a lot of common household devices (dishwater, etc.) as well as the option to implement a different device.
[[Bild:Passive-innerloads_scope.png|Device scope|right]] 
For each device, the quantity and the energy demand are needed. Additional data is needed for some devices: E.g. the dishwasher can be connected with the DHW or cold water. 
If the inner sources of the building are not known yet, WUFI contains a standard set of devices in a common household which can be used by clicking on "standard dataset".
 

== Non-residential building ==
=== Utilization pattern ===
[[Bild:Passive-innerloads_nonres_utipattern.png|thumb|right|Utilization pattern]]
The mandatory data for utilization patterns is given over the columns of the table. The additional data is useful, depending on where the pattern is attached.
 
=== Occupancy ===
[[Bild:Passive-innerloads_nonres_occupancy.png|right|thumb|Occupancy]]
Here the number of occupants of the building is defined as well as humidity sources. When it comes to the activity of the occupants, WUFI can differ between children, sitting adults and standing adults. It is also possible to define the pattern for these people as well the quantity of people following this pattern. 
The additional data section contains a value about additional heat losses through evaporation and toilet usage/settings. 
If the simulated building is a school, WUFI has default values for it.
 

=== Office equipment ===
[[Bild:Passive-innerloads_nonres_offequipment.png|thumb|right|Office equipment]]
Any office equipment can be enumerated here. WUFI itself knows the following devices: PC, monitor, copier, printer, server and the telephone system. If different devices are needed, they can be inserted in the "user defined" scope. "User defined" devices can not be attached to a utilization pattern, therefore the utilization hours/year have to be given. 
The printer and copier also have an additional data section. The hours of utilization in energy saving mode in hours/year can be defined, but are optional.
 

=== Kitchen equipment ===
[[Bild:Passive-innerloads_nonres_kitchequipment.png|thumb|right|Kitchen equipment]]
Kitchen appliances can be defined here. WUFI provides the options cooktop, dishwasher and refrigerator. Use the "user defined" scope if different appliances are needed.
 

=== Lighting ===
[[Bild:Passive-innerloads_nonres_lighting.png|thumb|right|Lighting]]
The required lighting is estimated depending on the amount of daylighting. Therefore data on room geometry, glass transparency and occupancy (utilization pattern) is needed.

Passive2:PH case

2014-05-19T22:07:22Z

LisaWhite:

== General ==
=== Parameters ===
[[Bild:Passive-phcasegeneral.png|right|General]]In this section the building category is chosen [[Bild:Passive-phcase_residentscope.png]] and the occupancy type is chosen depending on which category is appropriate for the simulated building. There are different options, depending if the building is residential or not. 
<div class="tleft" style="clear:none">[[Bild:Passive-phcase_residental_scope.png|Residential]]</div>
<div class="tleft" style="clear:none">[[Bild:Passive-phcase_nonresidental_scope.png|Non-residential]]</div> 
This choice influences the internal loads/heat gains. 
The indoor temperature defines the mean indoor temperature during the heating period. The tooltip recommends 20°C (68°F) for residential buildings. For non-residential buildings, the calculation method is described in EN 13790. 
The internal heat gains can either be calculated depending on the equipment or a predefined default value can be used. 
There are two options for the occupancy setting: design and verification. The verification setting determines occupancy by the treated floor area and uses a predefined default value for internal gains. The design setting uses the occupant quantity from inner loads, as well as a calculated value for internal heat gains. Design is the default setting for non-residential buildings and cannot be changed.
 
The number of units represents the amount of dwellings in the building.
=== Zones ===
Additional zones can be implemented here, to calculate different zones at the same time. They can also be named here.

== Additional data ==
=== Required data ===
[[Bild:Passive-phcase additionaldata.png|right|Additional data]]
The first two values describe the lower limit of indoor temperature achieved by ventilation and the maximum indoor temperature during summer. 
The design air volume flow rate is defined by the maximum of either 
a) required supply of fresh air per person * number of occupants or 
b) the sum of the design flow rate in the ventilation/rooms tab. 
To account for the air tightness of the building, a measured value from the blower door test (ACH 50 test) and the net air volume are required. 
Another important parameter for the calculation of the sensible cooling demand is the Max. Humidity Ratio. If the Humidity Ratio of the outer air (defined by the ambient temperature and the dew point) for a specific month is greater than this value, it is usually necessary to dehumidify the air (see table on bottom). 
For the building wind exposure, WUFI has predefined values, which can be chosen from the "Building wind exposure" scope. You can also use the "User defined" tab and input values yourself. 
[[Bild:Passive-phcase_adddata_scope_wind.png|Scope wind exposure]]

=== Optional Data ===
These values can be entered if available but are not necessary. If not defined, WUFI does calculate them.
=== Calculator humidity ratio ===
This is a little tool to calculate the maximum water vapor content in the air, depending on the air temperature and the dew point. You can then set the calculated maximum humidity ratio into the column in the table above. 

== Foundation interface ==
[[Bild:Passive-phcase_foundint.png|right|Foundation interface]]
WUFI® calculates the ground temperature depending on the type of foundation (Reference:EN ISO 13370). There are four different types are available. You also have the option to let WUFI detect the given type by itself or input your own ground temperature measurement. This measurement must be entered in the climate file and will be shown in the fourth row of the [[Passive2:Dialog_Climate#Climate|Climate tab]]. 
[[Bild:Passive-phcase_foundint_scope.png|Foundation scope]]
=== Parameters ===
Depending on the type of foundation, different values are needed for WUFI. You have the option to either specify them yourself or let WUFI detect them automatically.

Passive2:HVAC

2014-05-19T20:51:30Z

LisaWhite:

== General ==
[[Bild:Passive-hvac_general.png|HVAC general|right|thumb]]
The HVAC devices for the building are defined in this section. This means usage and also energy/work distribution if multiple devices are used for the same task. For a list of possible devices see the [[Passive:Dialog_Database_HVAC_new|HVAC database]] and for information about the needed input of the respective device, see [[Passive:HVAC Devices|this page]].
 

== Distribution==
In the Distribution tab, the distribution of the generated heating, cooling, DHW, and ventilation is defined. The heat losses due to pipes and ducts are taken into account for the final calculation.
=== Hydronic heating ===
[[Bild:Passive-hvac_distribution_hydrhea.png|HVAC hydronic heating|right|thumb]]
These inputs are only required, if the Hydronic Heat distribution is accomplished by pipes. For the estimation of the heat loss, data about the pipe length, geometry, its construction and the temperature difference between inside fluid and outside is necessary. The heat loss coefficient has to be calculated by a separate tool which is implemented on the GUI of WUFI. 
WUFI distinguishes between warm regions and cold regions. In warm regions the indoor temperature is used for the calculation of the temperature difference, whereas for the cold region the temperature has to be defined.
 

=== DHW ===
[[Bild:Passive-hvac_ditribution_dhw.png|HVAC DHW|right|thumb]]
The DHW distribution is very similar to the Hydronic Heating distribution. Additional information about the running hours of the circulation are required. Usually the DHW circulation is running 24 hours per day, apart from single family houses, which are running around 8-12 hourse a day. 
Furthermore, the length (sum) and diameter of individual pipes need to be entered. The pipes are starting from the circulation and usually end at the water tap.
 

=== Ventilation ===
[[Bild:Passive-hvac_distribution_ventilation.png|HVAC ventilation|right|thumb]]
The distribution of the ventilation is accomplished by ducts. Each duct has to be assigned to one or more ventilation unit(s). The duct length, geometry and insulation influences the efficiency of the ventilation system. Unlike other components it is not necessary to create an assembly for the pipes as the thermal resistance is only estimated by the insulation.

Passive2:Dialog Climate

LisaWhite:

Unlike WUFI®Plus, WUFI®Passive uses monthly climate data rather than hourly data.

== Localization ==
[[Bild:Passive-case1_localization.png|right|thumb|Localization]]
The climate file is chosen in the localization tab. WUFI's predefined climate is a reference year of Germany and can be altered by using the "user defined" tab in the scope and by browsing the desired climate file. 
Due to WUFI®Passive not using hourly data, different climate files and formations are needed. So far WUFI can read .txt and .xls files as seen in the screens below and in [http://www.wufi-wiki.com/wufifilme/flash/climate_data_input.swf this movie]. To obtain these files/formation you can use meteonorm. 

<div class="tleft" style="clear:none">[[Bild:Passive-case_1_passivebsptxt.png|thumb|Example .txt]]</div>
<div class="tleft" style="clear:none">[[Bild:Passive-case_1_passivebspexcl.png|thumb|Example .xls]]</div>
 

== Climate ==
The climate tab summarizes temperature and radiation data in a table and a graph. The picture on the right can be used as a reference for the description.
[[Bild:Passive-case1_climate.png|thumb|right|Climate]]
=== Temperature ===
The upper table shows the monthly mean ambient temperature and, if given in the climate file, the sky, ground and dew point temperature, though they are not necessary for the calculation. The extreme weather condition on the right end are needed to calculate the heating and cooling loads of the building.
=== Solar radiation ===
The lower section contains the mean monthly solar irradiation, separated into the four cardinal points and also the extreme weather conditions.

== Primary energy/CO2-factor ==
[[Bild:Passive-case1_primaryenergy.png|right|Primary Energy]]
In this tab, you can see and set the primary energy factor (PEF) and the CO2-emission factor (CO2EF). 
The PEF multiplies with the energy demand and varies depending on the chosen material, because the PEF is influenced by both the production process and the transportation of the energy source. 
The CO2EF converts the energy demand into an equivalent amount of CO2. These two factors are important when looking into the sustainability of the passive building. 
[[Bild:Passive-case1 energy scope.png]] 
Though differences are minor, WUFI knows 3 different standards regarding the values of this table. If you have different values, you can create your own table in the "user defined" section.

== Climate ==
The climate tab summarizes temperature and radiation data in a table and a graph. The picture on the right can be used as a reference for the description.
[[Bild:Passive-case1_climate.png|thumb|right|Climate]]
=== Temperature ===
The upper table shows the monthly mean ambient temperature and, if given in the climate file, the sky, ground and dew point temperature, though they are not necessary for the calculation. The extreme weather condition on the right end are needed to calculate the heating and cooling loads of the building.
=== Solar radiation ===
The lower section contains the mean monthly solar irradiation, separated into the four cardinal points and also the extreme weather conditions.

== Primary energy/CO2-factor ==
[[Bild:Passive-case1_primaryenergy.png|right|Primary Energy]]
In this tab, you can see and set the primary energy factor (PEF) and the CO2-emission factor (CO2EF). 
The PEF multiplies with the energy demand and varies depending on the chosen material, because the PEF is influenced by both the production process and the transportation of the energy source. 
The CO2EF converts the energy demand into an equivalent amount of CO2. These two factors are important when looking into the sustainability of the passive house.

Though differences are minor, WUFI knows 3 different standards regarding the values of this table. If you do have different ones, you can set your own table in the "user defined" section.

LisaWhite:

Unlike WUFI®Plus, WUFI®Passive does not use hourly data.

== Localization ==
[[Bild:Passive-case1_localization.png|right|thumb|Localization]]
The climate file is chosen in the localization tab. WUFI's predefined climate is a reference year of Germany and can be altered by using the "user defined" tab in the scope and by browsing the desired climate file. 
Due to WUFI®Passive not using hourly data, different climate files and formations are needed.
