Abstract
Lecture about the Borgen Community Centre, a demonstration building within the EU project «Bringing Retrofit Innovation to Application in Public Buildings» (BRITA in PuBs). The aim of the BRITA project was to increase the market penetration of innovative and effective retrofit solutions for energy conservation and implementation of renewable energy sources, with moderate additional costs. In the pre-project phase SINTEF had the role as facilitator, and researchers from SINTEF and NTNU were involved as expert advisers regarding environmental issues. The task of sustainable retrofit did not have a purely technical focus, but a more integrated approach was applied, combining building design and energy technologies, also including more «soft issues» such as process and social issues. In order to create a vital local community and meet the need for more efficient use of resources, joint location and coordinated use of facilities were emphasised. In addition to a secondary school there are facilities for health care services and leisure time arrangements.
