The Norwegian IEA Task XIII house.

The Norwegian solar low energy dwelling developed within Task 13 of the International Energy Agency's Solar Heating and Cooling Programme, is a two-storey row house apartment of approximately 120 m2 floor area. The IEA dwelling is being constructed at Hamar, 120 km north of Oslo, and it will be used for media personel lodging during the Winter Olympics in 1994. The IEA dwelling will be superinsulated, with U-values of 0.11, 0.14, and 0.13 W/m2.K for roof, walls and floor respectively.

The Majrovagen project. Experimental building design for low energy use and good indoor climate.

The Majrovagen project is the result of a design competition, held by the City of Stockholm and the Swedish Council for Building Research in 1990. The competition is a part of the efforts made by the City to promote efficient energy use and healthy buildings. Efficient energy use will help reduce disruption to the environment, the need for new, expensive energy plants, and, not least, the energy costs of the inhabitants of Stockholm. Three different projects with mu It if amity houses of about 60 apartments each were chosen by a Jury to be built in the same area during 1993.

A Swedish - German energy efficient apartment building with attached sunspace.

Two identical apartment buildings were built, one in Germany, and one in Sweden, in 1986. The idea was to create energy efficient housing at a low cost, using Swedish building technology and German heating and ventilation technology. The Swedish building code, which is more stringent in terms of energy conservation than the German one, was applied in both countries. The paper examines the performance of the buildings.

The energy impact of ventilation and air infiltration in an atrium.

Many modern office and residential buildings in Sweden include an atrium. The atria are often mechanically ventilated and sometimes they are heated. Very little is know about the ventilation and air infiltration in built atria. These issues were examined in an apartment building with a non-heated and mechanically ventilated atrium, built in 1986 in Sweden. The ventilation of the atrium is coupled to the apartments.
