Models common air conditioning systems including: In the morning, east-facing walls and windows are exposed to direct sunshine. Overview of the Main Heat Sources Although there are many ways in which heat can be generated, directly or indirectly, the following are some of the main sources in building interiors: The heat held by outdoor air comes in great part from the sun, but it can also originate from vehicles or from other buildings.
Heat load calculations are performed for all areas of the building, and ca,culator total building load is determined as well.
