In the Netherlands, many attempts have been made to introduce and implement advanced energy efficient domestic ventilation systems. This especially applies to balanced ventilation with heat recovery, one or multizone air heating systems with he

This paper discusses some inference problems in measurement programs. The 1991 Swedish energy and indoor climate survey is chosen for the purpose of illustration. The Swedish survey is carried out within the research program "Conservation of Electricity in Existing Buildings" (ELIB), consists of three projects: 1. Technical characteristics of the Swedish housing stock; 2. Indoor climate of the Swedish housing stock; 3. Energy conservation potentials in the Swedish housing stock.

Measurement of indoor relative humidity using a passive sampler for water vapour.

As part of the energy and indoor climate survey recently carried out in Sweden (the ELIE study) a simple, inexpensive but reliable passive sampler for estimating monthly averages of relative humidity has been developed. The diffusion sampler consists of a 5 ml plastic tube prepared with lithium chloride monohydrate as trapping medium. After necessary calibration of this particular design of sampler the relative humidity can be calculated from the weight change of the sampler, the time of sampling and the average temperature during this period.
