Define the Concept Building Thermal Information

Setting up the concept building's thermal information is done in the Thermal Info tab.

General settings define the calculation standard to be used for energy simulations as well as the building type and default room type.
Constructions settings define the material constructions used to model the different surface types associated with the concept building.
Internal conditions settings define the concept building's thermal conditions for winter and summer as well as internal heat gains. These properties are used for running energy simulations.

In the General settings, select ASHRAE 2007 from the drop down menu provided for the Standard setting. Sets the ASHRAE 2007 standard is set for simulation runs on the conceptual building.
Select Office from the drop down menu provided for the Building type setting. Office buildings have different thermal properties than hospitals for instance.
Select 2007: Office - Open Plan from the drop down menu provided for the Room type setting. The room type selected here is used when modeling the concept building's overall space (Room).
In the Constructions settings, select material constructions to apply to the external surfaces of the concept building from the drop down menus provided. U Values are displayed for selected constructions.
(Optional) If you want to use a construction which not displayed in the Conceptual Modeling dialog, then click Material manager to open the Materials Manager where you can select or create material constructions.
In the Internal conditions settings, keep the defaults for the internal design temperatures and humidity (% Saturation).
Note: The values entered here are used for steady state calculations.
Keep the defaults for winter and summer infiltration rates.
Note: Infiltration rates entered for the Winter and Summer sub-settings are handled as an arithmetic average in steady state calculations.
Click Apply to apply changes to the concept building.
