Insulation and airtightness of 6 low energy houses at Hjortekaer, Denmark.

Describes energy measurements carried out on 6 detached single family low-energy houses in Hjortekaer, 1979-1980. Discusses a few typical construction details, to illustrate solutions to the problem of cold bridges and to demonstrate ways of obtaining air tight constructions. Measures the achby the tracer gas decay method, showing results ranging from 0.02-0.12 ach. Correlates these with pressurization tests also made. By means of regression analysis of thermal calibration data tests 3 different models for heat loss equations. Two very simple models show good agreement with calculated heat loss. The present analyses are considered a pilot study for working out a short term calibration test procedure for low-energy houses.
