Energy and resources, material choice and recycling potential in low energy buildings

Abstract
This paper presents three Swedish residential low energy buildings regarding the total need of energy in a life cycle perspective, the environmental impacts, effects of choice of material and the recycling potential. The calculated energy need for operation (space heating, electricity, hot water) was in average 50 kWh/m2 floor area per year. Simulations were made with four electricity mixes. For a service life of 50 years, production and transportation of materials accounted for 50-60 % of the impacts in the case representing the actual energy mix. This changes the prevailing picture that operation accounts for the main part of energy use. The recycling potential was about 35 %. Choice of materials affected the energy for the material part...
