Question

Quizplus · Accepted Answer

An external thermal storage system is not one of the methods for utilizing free energy in buildings. However, using the building mass as a thermal storage system is. Many building sites have the potential to satisfy the majority of human needs through passive systems. Day lighting prevents the need for artificial lighting during sunlit hours. Natural ventilation, such as operable windows, allows fresh air circulation while minimizing the required capacity of the HVAC system. Well-insulated walls designed to reflect light in the summer and absorb it in the winter will help minimize heating and cooling energy needs.
