Our work is concentrated on increasing efficiency in energy use, the conservation of the outdoor environment, as well as the importance of good indoor environment for health, well-being and productivity.

Central issues underlying this work are the greater demand for power and energy in the Norwegian electricity supply system, together with a closer connection to a common European power market. Environmentally friendly and flexible energy systems will have increasing significance in coming years and is therefore central in our work.
 
The group has the following main focus areas:

• Flexible energy systems
• Hydronic heat distribution and cooling
• District heating/cooling
• Central energy plants
• Energy efficiency
• Thermal planning
• New, renewable energy sources
• Heat pumps
• Biomass/solar energy
• Building automation

While others place considerable weight on the development of components, we have concentrated on giving the total energy system in a building the correct, appropriate design. Important key-words for us are "systems thinking and the holistic approach" and "integrated systems".

BIEN (Building Integrated Energy Efficiency) is a training programme in the efficient use of energy in buildings.  BIEN is developed for university education and is used as a reference work for advisers, consultants, entrepreneurs and architects.
