Life cycle assessment of a domestic natural materials wood house

We conducted a project entitled "Achieving Climate Change Abatement and Comfortable Life by a Partnership between Forestry and Natural Material Housing (NMH) in Urban Areas," which aims to achieve carbon neutral housing by 2050 by linking forest management to the use of domestic wood in environmentally friendly Natural Materials Housing. In this paper, we conduct long term Life Cycle Assessment of CO₂ emissions from afforestation stage to ultimate demolition of the house, encompassing the following stages: afforestation work and log cutting, lumber production, house building, use of the house (with main emissions coming from energy consumption for space heating and cooling, cooking, hot water supply, lighting, and appliances), repair, demolition, and waste treatment. Analysis results indicate that Life Cycle CO₂ emissions from Natural Materials Housing are low, when compared with standard cases.
