摘要:
Novel environment-friendly structural components having high thermal insulation performance were proposed, and their effect on the reduction of greenhouse gas emissions was investigated in different climate regions for various fuels. The amount of CO2 and SO2 emissions of the fuels were calculated. The results show that the pro-posed component provides an energy saving of 11 kWh/m(2)-year in an insulated building in the 4th region, while a great amount of energy-saving of 31.2 kWh/m(2)-year was achieved without insulation case. The annual energy saving rate reached 21.7 %. The parametric analysis results indicate that the maximum performance was achieved for a wall component thickness of 0.21 m for the case of without-insulation. The largest energy-saving occurred for the building using electricity-heating in the 4th region. The annual cost saving reached 3.03 $/m(2) for the electricity case in the 4th region. The highest carbon emission occurred in the case of coal. Natural gas was decided to be the cleanest way of heating. Electricity caused the largest emission after coal in the investi-gated region. The reduction in the carbon emission reached 18.7 kg-CO2/m(2).year for the coal. The maximum reduction in carbon emission reached 22 % for the proposed components.
