From Direct Solar Gain to Trombe Wall: An Overview on Past

Direct solar gain is the most basic form of solar gain of heat. The solar radiation penetrating through the glazing is absorbed by the thermal mass built into the floor and walls, where it undergoes photothermal conversion . Its quantity is determined by the structural features of the building, the orientation of the glazing relative to the

Solar Gain

Solar gain can also be transferred to the building by indirect or isolated solar gain systems. Objects having large thermal capacity are used to smooth out the fluctuations during the day, and to some extent between days. Solar Heat Gain Co-efficient (SHGC) is the fraction of incident solar irradiation admitted through a window, both directly transmitted, and absorbed and

SUMMARY AND COMPARISON OF METHODS TO CALCULATE SOLAR HEAT GAiN

The solar heat gain from a glazing system consists of two components: 1. solar radiation passed through the window and absorbed indoors and 2. solar radiation absorbed within the glazing system and redirected to the indoor space by heat transfer. The first of these two quantities is determined by the solar optical calculation. In residential windows it is usually the larger

SOLAR ENERGY

Since passive systems are designed to maximize solar gains, there is a high risk of overheating, not only in the summer but also towards the end of the heating season when most systems should be operating at their maximum performance. The thermal discomfort of unwanted solar gains can be avoided by preventing the initial solar gain by using

Solar gain

Solar gain (also known as solar heat gain or passive solar gain) is the increase in thermal energy of a space, object or structure as it absorbs incident solar radiation. The amount of solar gain a space experiences is a function of the total incident solar irradiance and of the ability of any intervening material to transmit or
