Low energy buildings in Sweden
Project leader
Professor Bahram Moshfegh
Sustainable development in buildings requires management of materials and energy both during the construction and use of residential housing. Forty percent of Sweden's total energy use is used for buildings and thus a large part of Sweden's carbon dioxide emissions can be attributed to buildings. The environmental impact of different types of energy, however, is different and various kinds of energy have different pre-requisites to be used for different purposes. Making a distinction between different energy forms and their areas of use can demonstrate opportunities to improve energy efficiency further. EXERGY is a term that describes the amount of energy which can be converted to work and thus provides a measure of energy quality. In an Exergy Analysis of a building opportunities for efficiencies can emerge that do not appear as clearly in an Energy Analysis. The energy demand for a building is not only related to the energy used in the building. Also the construction of buildings leads to use of energy and subsequent environmental impact. Sustainability also includes a good indoor environment that offers comfort and is not harmful to people who are in the houses. All proposed measures in the project will preserve or improve the indoor climate in the building. In the project, a tool for simultaneous measurements of energy use,exergy use and built-in energy will be studied. A number of different measures that range from various building materials and various forms of primary energy to different types of systems for heating, cooling and ventilation, will be studied. The goal is to reduce carbon dioxide emissions from the building's entire life cycle and the tool will be used to demonstrate the potential for improved efficiency in various parts of the building's lifecycle and where measures in existing and new buildings should be implemented for maximum effect.
