Heating, cooling and ventilating buildings accounts for almost half (40%) of Sweden’s total energy use. As this is highly related to environmental effects, the reduction of energy use in buildings is one of the most important aims in society today. The most important factor for residents and users of buildings is to reduce the cost of energy without affecting the comfort and function of the building. It is often possible to improve the comfort and reduce energy use at the same time. Reducing the need to buy energy increases the user’s economic security when energy prices increase. Researchers at LTH and Lund University are working on these issues.
Research is concerned with all aspects, from the development of computational methods, components and engineering systems for buildings, to the use of renewable energy and the development of design tools. The demands and actions of the users are also important. The research carried out has applications in Sweden and in other countries, and is often carried out in international projects. There is also a great deal of cooperation with industry through demonstration projects, for example, the construction and evaluation of energy-efficient buildings. New buildings and energy-efficient renovation of existing buildings are central issues. Research is being carried out by research groups at various divisions, for example, Energy & Building Design, Building Physics, Building Services, and Housing Development & Management.
An interdisciplinary project involving researchers from LTH and Lund University, EEBuild (Energy-Efficient Buildings) has recently been initiated. The departments and divisions involved are: the International Institute for Industrial Environmental Economics, Energy & Building Design, Building Physics, Sociology and the Research Policy Institute.
