Sweden, the country's total energy consumption, construction of a fourth-heating, and the total energy consumption in buildings, a heating account for 87%. Therefore, we should first residential energy-saving insulation.

Nordic is located in Sweden, the long cold winter, cool in summer and short-term, all of the buildings is the main heating energy consumption. Therefore, building energy efficiency has become the top priority of reducing the energy saving Sweden. Sweden residential energy conservation from the use of dark-colored exterior paint and building materials, which can in the daytime as much as possible to absorb solar energy. Building materials in the wall, the main use of hollow brick walls and composite technology to enable the construction of solar energy absorbed easily deposited in the walls, so the rapid loss. Currently, ground-source heat pump has been gradually entering the Swedish families, it than electric boilers and boiler fuels are energy saving, users can save an average of 30% to 40% in heating costs.
