The Norwegian Government Environmental Fund is a loan scheme administered by the Norwegian Industrial and Regional Development Fund. The scheme was established to provide funding for projects that help to reduce emissions of greenhouse gases and other environmentally harmful gases, and provide funding for energy efficiency investments. "Oko-bygg" is a development programme that was started in 1998. It provides information, advice and grants to promote the use of eco-efficient technology, including more efficient and flexible energy use in the construction industry. The programme will end in 2002. The Norwegian State Housing Bank offers various loan and grant schemes for residential energy efficiency measures. From 2002 the housing bank also offers NKr 140 000 in extra loans and NKr 10 000 in grants to homebuilders who invest in water heating systems based on bioenergy, solar or that use heat pumps.
