| Research Abstract |
In this report, we proposed the concepts and the techniques to renew buildings built with reinforced concrete, particularly apartment houses by using the external insulation. The external walls of a test house were thermally insulated with glass wool or foam polystyrene. The temperature and humidity distribution in walls of the test house were measured through the year. The external surface temperature distributions of apartment houses as the field survey were measured during the coldest season. The effects of Heat Bridge were not recognized in the case of apartment house with the external insulation.
