Research Abstract	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.
