First, the new house, using building materials commonly used in the market at present, adopts external wall insulation outside the residential envelope, enhances horizontal insulation on the roof, and adopts insulating glass three-layer broken cold bridge insulation window as the external window, which will produce the effect of being warm in winter and cool in summer. Some buildings have an air layer in the wall, built-in waterproof and reflective materials, and a double-layer cap at the top: the first layer cap is a solar thermal storage plate, which uses solar energy for air conditioning, cooling and heating or providing hot water; The second layer of cap is thermal insulation cap, and the roof is made of high-density foam board, which can prevent summer sun exposure and reduce the indoor natural temperature by 2℃. And every time 1℃ is reduced, the energy consumption of air conditioning is reduced by 10%, and people living in it feel more comfortable.
Second, the house faces north and south.
Third, a kind of "floor air conditioner" popular in the north is actually more suitable for family houses below 300 square meters. There are many hot water pipes under the floor, which use air source heat pump to generate hot water. In winter, hot air comes from people's feet. Cold water is produced in summer, and the household central air conditioning system is composed of fan coil units, and the cold air is blown down from the face first. This noise-free "floor air conditioner" will generate energy equivalent to 3 kWh for every 65,438+0 kWh when absorbing heat from the air.
