5. Why is Energy Efficiency important in Norway? Energy consumption for heating, ventilation and cooling could be very high without focus on energy efficiency   High requirements to the indoor environment   High no. of m 2 per person   “Artic” winters and “Mediterranean” summers Norwegian energy efficiency knowledge and experience well developed during decades; architects, consultants and experts

6.  Regulations and standards  Education, training and capacity building; local experts and energy managers  Informational dissemination and awareness raising  Energy efficiency grants and loans for investments  Demonstrations  R&D projects  Special campaigns  ……… Norway policy on Energy Efficiency in Buildings; a variety of measures supporting the market development Norwegian energy efficiency knowledge and experience “exported” for several years – supporting local and regional sustainable development.
