Assesses the quality of retrofit work carried out in 329 Swedish houses, which had received government energy-saving funds. Describes the selection of dwellings, the measurement methods employed (including thermography, pressure testing, tracer gas and heat flow) and the results.< In most houses, insulation work in attics and on external walls had been carried out satisfactorily. However, the houses were still not air tight and exhibited high ventilation figures (for pressure tests 8 air exchanges per hour at 50 Pa and for tracer gas tests 0.6 air exchanges per hour). It is probable that defects in the original construction were never corrected.
