The prime Passive solarbuilding advantage is that the design uses sunshine to heat and light homes. Passive solar heating is the least expensive way to heat your new home and is one of the most attractive strategies available for energy-efficient construction and sustainable building. It is usually part of the design of the building itself, using certain materials with correct placement of windows including correct placement the building itself.
Optimum Solar Gain Through Window Placement
Because much of a building’s heat is lost through its windows, the majority of windows in our buildings are located on the southeast, south and southwest walls for optimum solar gain. In the winter when heating is required, the sun is low in the sky, which allows the heat to penetrate into windows on the southerly faces of a structure. In the summer, south-facing windows are shaded by roof overhangs, shades or awnings to keep out the hot summer sun.
Polyurethane SIPs Panels
A successful passive solar building also needs to be very well insulated in order to make the best use of the sun’s energy. Polyurethane SIPs are unsurpassed in performance and the result is a quiet and comfortable space, free of drafts and cold spots. Passive solar design can also achieve summer cooling and ventilating by making use of convective air currents which are created by the natural tendency of hot air to rise. As renowned architect Frank Gehry proclaimed, “sunlight shouldalways be utilized because it”s free.”So not only is passive solar building eco-friendly it can also substantially lower your energy costs.
