The General tab displays project information that only affects a heating and cooling loads analysis. You can modify this information before a loads analysis or after to make it comply with your specifications.
The General tab contains the following options:
- Building Type: Specifies the building type for the project.
- Location: Specifies the geographical location for the project.
You can change this information by clicking , and using the Manage Place and Locations dialog.
- Building Service (Default Space Service): Specifies the heating and cooling system for the project.
- Building Construction (Default Space Construction): Specifies the constructions type for the building.
You can change the construction type and its corresponding constructions by clicking , and using the Building Construction Dialog.
- Building Infiltration Class: Specifies an estimate of outdoor air that enters the building through leaks in the building envelope.
Infiltration can be specified as:
- Loose - 0.076 cfm/sqft for tightly constructed walls.
- Medium - 0.038 cfm/sqft for tightly constructed walls.
- Tight - 0.019 cfm/sqft for tightly constructed walls
- None - infiltration is excluded from the calculation of loads.
- Report Type: Specifies the level of information provided in the heating and cooling loads report.
You can specify Simple, Standard, or Detailed for Report Type.
- Ground Plane - (read only) is the level that serves as the ground level reference for the building. Spaces below this level are considered to be underground. The default level is zero.
- Project Phase - (read only) is the stage of construction (Existing, New Construction).
- Sliver Space Tolerance - (read only) is the tolerance for areas that will be considered sliver spaces. See Accounting for the Volume of Cavities, Shafts, and Chases.
- Use Loads Credit - accounts for heating or cooling “credit” loads that take the form of negative loads. For example, heat that leaves a zone through a partition into another zone can be a negative load/credit.
