Energy upgrading measures improve also indoor climate

A new survey shows that the economy is what motivates Danish owners of single-family houses the most to start energy upgrading, and that improved indoor climate is also an important factor. After the upgrading, homeowners experience both improved economy and indoor climate. Measurements in a number of new low-energy houses show that it is possible to obtain good thermal comfort and air quality in well-insulated houses even with large window areas. This experience is useful in the upgrading of existing homes.
