Large commercial buildings are most often dominated by internal loads, which are the heat gains or losses from people, equipment, lighting, and other sources inside the building. Internal loads can affect the heating and cooling loads and the energy consumption of the building. Therefore, reducing internal loads can improve the building’s energy efficiency and performance. References:
