Should we really put less energy into building the future? Yes, but only through increased focus on energy efficiency.

IVT has for many decades worked with heat pump technology, and is now one of the leading companies in the world in this field. The basic technology, known since almost a century, is to use the energy created from the sun stored in rock, soil or air for heating.

CIENS stands for Centre for Interdisciplinary Environmental and Social Research, and is a strategic research collaboration between independent research institutes and the University of Oslo. The office building where the centre is located is in itself a study in energy efficiency and environmental solutions.

Oslo's first street lights were lit in 1848. Since then they have become both brighter and smarter.
