CO₂ EMISSIONS FROM THE CONSTRUCTION AND USE OF WELL-INSULATED AND AIRTIGHT HOUSES BASED ON MEASUREMENT SURVEY

An evaluation of LCCO₂ from detached wooden houses constructed by conventional methods Part 1

Abstract

CO₂emissions from the construction and use of houses have been increasing. In order to promote the reduction of CO₂ , it is necessary to know the exact amount of CO₂ emissions from houses. First, the authors measured the exact weight of the construction materials and waste. Next, the authors researched the inhabitants' daily schedule and measured the energy consumption from using the house . The following results were obtained.
1) The authors discovered the relationship between the energy consumption and the inhabitants' daily schedule.
2) The amount of electricity consumed was 30.6GJ/year for the first year and 28.9GJ/year for the second year.
3) The amount of CO₂ emissions from both the construction and two years use of the house was 389.07kg-CO₂/m².
4) The authors recalculated the amount of CO₂ emissions into the amount of CO₂ emissions per area of ceiling, floor and outer wall to discover the relationship between CO₂ emissions from the construction and CO₂emissions from use of the house.
