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
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.
