Energy Use and Environmental impacts of the Swedish Building and Real Estate Management Sector

• One of the key features of environmental policy integration in Sweden is sectorresponsibility. The National Board of Housing, Building and Planning is responsible for the building and real estate management sector and should, as a part of this responsibility, assess the environmental impacts of this sector. The aim of this study is to suggest and demonstrate a method for such an assessment. The suggested method is a life cycle assessment, based on an input-output analysis. The method can be used for regular monitoring and for prioritization between different improving measures. For the assessment to sufficiently cover the Swedish Environmental Quality Objectives, complementary information is needed, in particular with respect to the indoor environment. According to the results, the real estate management sector contributes between 10% and 40% of Swedish energy use; use of hazardous chemical products; generation of solid waste; emissions of gases contributing to climate change; and human toxicological impacts, including nitrogen oxides (NOx) and particulates. Transport and production of nonrenewable building materials contribute significantly to several of the emissions. Heating of buildings contributes more to energy use than to climate change, due to the use of renewable energy sources. To reduce climate change, measures should therefore prioritize not only heating of buildings but also the important upstream processes.
