What is passive solar energy and how does it work?
- Regardless of the type of heat gain utilized, passive solar energy provides heat at little to no cost, aside from the slight variations in the design and construction of the building.
What is solar gain?
- Solar gain is a fundamental principle of Passive Design. Passive Design utilises the sun’s energy to create a comfortable internal environment; as the PassiveDesign.org - --- Solar Gain Home Principles of Passive Design Solar Gain Thermal Mass Super Insulation Airtightness Block Cavity System Timber Frame System MVHR Passive Construction
What is isolated solar heat gain?
- Isolated gain, depicted in Figure 3, uses solar collection and thermal storage that are separate from the actual living space, moving heat to the living space through natural or forced convection. Ventilation is also essential in this method of passive solar heat gain.
Why are low U-factors important in passively solar-heated buildings?
- In passively solar-heated buildings, low U-factors are important in reduces winter heat loss from large solar collecting glazing areas and in retaining heat collected during the day for use at night. Entry ways (air lock)
