Vision og businessidea, AF Energi & Miljøteknikk. We will use energy on saving energy. Vision We shall be Norways leading expertise and parner within right use of energy. Businessidea

AF Energi & Miljøteknikk We offer 4 different qualifications too the market; • Analyse and design of systemes for efficient energy use • We work out projects and enterprises - with guarantee of investment and result • Servicing, maintenance and modification – too keep the energycost low after enterprises

We also offer: design, development and managenent of energycentrals and district heating based on renewable energy • We have designed an energycentral in Oslo based on heatpumps with Europs larges storage of thermal energy in rock ground. • We design a loth of centrals based on biomass energy and wood pulp • In smaller areas it is normal to distribute both heating and cooling, with heatpumps that transform the energy
