- Earth coupled slabs maintain comfortable summer temperatures that can easily be raised by passive solar heating in winter
Construction Systems
- Earth coupled slabs are highly beneficial
- High thermal mass walls can be used if within glass to mass ratios (Glass to mass ratios compare the area of solar exposed, passively shaded, south/north facing glazing to the area of exposed, insulated internal mass -walls and floor- to avoid overheating passive solar houses). These ratios should be varied according to solar availability, diurnal temperature ranges, type and orientation of glazing and shading (ambient and diffuse gains).
- Low embodied energy walls, roofing and finishes
