7 Project aim Gain knowledge concerning the possibilities and limitation with glazed office buildings exposed to the Swedish climate, mainly with regard to energy and indoor climate. Included are - Further development of calculation methods and analyses tools - Improvement of analysis methodology - Calculation of life cycle costs - Development of advice and guidelines for design/construction of glazed office buildings in a Swedish climate - Strengthening and development of competence concerning resource efficient advanced buildings in Sweden. Åke Blomsterberg,
