摘要

In order to achieve the national goal of greenhouse gas emission reduction in building sector, it is essential that insulation performance of existing buildings should be improved.Built before 2001 when the building insulation regulation has been highly tightened, the old building accounts for 76.0% of total buildings in Korea.The aim of this study was to evaluate the actual insulation performance of the opaque outer wall in old buildings by field measurements.A variety of standards and relevant research which deal with the field measurement of thermal transmittance were surveyed.Outer wall U-values of old buildings were measured and compared with the required value prescribed in the insulation regulation enforced when evaluated buildings were designed.As results, actual insulation performance was found to be approximately two-thirds of required level prescribed in the insulation regulation.
