Use this dialog to perform a heating and cooling analysis for the building model.
To open the Heating and Cooling Loads Analysis dialog, click Analyze tab
Reports & Schedules panel
(Heating and Cooling Loads).
If an energy model exists, you are prompted to update or use the existing energy model. If no energy model exists, a new one is generated.
Building Service: Specifies the heating and cooling system for the building.
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 select Simple, Standard, Detailed, or Compact.
Use Load Credits: Allows for accounting of 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.
To run the Heating and Cooling Loads Analysis, click Run Analysis.
