ABSTRACT
A major objective of solar building design is the reduction or, if possible, elimination of the need for auxiliary heating or cooling. By utilizing the thermal storage capacity of the building, the designer may reduce the size of auxiliary heating/cooling systems. Heating systems may generally be separated into two main categories: convective heating systems that heat primarily the room air, and radiant or panel heating systems in which the source of heat is integrated into the building envelope or interior surfaces. Radiant heating systems operate in a mode similar to direct gain systems, that is, they rely on a high surface temperature (up to 29°C for floor heating) in a room, and lower air temperature.
