Which of the following strategies can be used to reduce the internal load of a building?
A . Decreasing lighting power
B . Oversize the HVAC systems
C . Install low reflective exterior facade
D . Increase the insulating value of the glazing and window frame system

Answer: A

Explanation:

Decreasing lighting power is a strategy that can be used to reduce the internal load of a building. Internal load is the amount of heat generated within a building by its occupants, equipment, and lighting1. Reducing lighting power can lower the internal heat gain and thus decrease the cooling demand and energy consumption of the building2. Other strategies to reduce internal load include using energy-efficient appliances, natural ventilation, daylighting, occupancy sensors, and shading devices3.
