In commercial buildings, the heat generated by lights does not seriously affect control of the heating system?

In commercial buildings, the heat generated by lights can indeed seriously affect the control of the heating system. Lighting produces a significant amount of heat that must be accounted for in the building’s overall thermal load. If the contribution from lighting heat is not considered, it can lead to improper operation of the heating, ventilation, and air conditioning (HVAC) system. The heating system could run inefficiently or continuously, even when it is not needed, to offset the additional heat generated by lights.

By recognizing that lighting contributes to the internal heat gains within a space, building managers can more accurately control the HVAC settings to maintain comfortable and efficient operating conditions. This understanding is crucial in managing energy costs and ensuring occupant comfort. Therefore, it is not accurate to state that the impact of heat from lights does not seriously affect heating system control; this heat must be balanced with the heating system's output to maintain environmental comfort.
