Building renovation with interior insulation on solid masonry walls in Denmark - A study of the building segment and possible solutions

摘要

The segment size of the Danish multi-story building stock from the period 1851-1930 is established through a unique major database managed by the Danish authorities. The outcome illustrates a large segment with 219,202 apartment units distributed over 14,832 unique buildings, all sharing characteristic geometry. Reduction of average U-value for the exterior fa ade is investigated in different dimensions, insulation degrees and thicknesses. The analysis shows that compared to insulation of only the infill walls below windows, fully covering insulation yields further 100-150% average U-value reduction. The large segment poses arguments for research into challenges raised by full surface insulation. (C) 2015 The Authors. Published by Elsevier Ltd.
