A study on how to reduce CO_2 emissions from the construction and use of well-insulated and airtight houses constructed by conventional methods

我们测量了两个用常规方法建造的隔热和密闭良好的房屋的建筑材料和垃圾的准确重量。第一套住房于2009年12月完工，第二套住房于2011年4月竣工。我们计算了建筑材料和垃圾的二氧化碳排放量。我们测量了2009年12月完工的房子的日常用电能耗。我们计算了这所房子使用16个月的二氧化碳排放量。然后我们考虑了如何减少与房屋建设相关的CO_2排放。据此，我们计算了与房屋建设相关的CO_2减排。

We measured the exact weight of construction materials and waste for two well-insulated and airtight houses constructed by conventional methods. The first house was completed in December 2009, the second house was completed in April 2011. We calculated the amount of CO_2 emissions from construction materials and waste. We measured the energy consumption regarding the everyday use of electricity of the house which was completed in December 2009. We calculated CO_2 emissions for 16 months' use of the house. We then considered how to reduce CO_2 emissions connected with the construction of house. From this, we calculated the reduction of CO_2 emissions connected with the construction of the house.
