Minimum ventilation rates as a basic requirement for energy conservation - results from an international co-operation

To propose guidelines for minimum ventilation rates which are sufficiently large to meet the demand for fresh air without unnecessarily wasting energy, in IX "Minimum ventilation rates" within the IEA Programme "Energy conservation in buildings and community systems" nine countries are co-operating. The participants have in a first step summarised existing knowledge, national standards and current and required research. The work that was required covers a wide range of disciplines, from hygiene and medicine on one hand to engineering and building science on the other. The Annex IXprovides a highly suitable mechanism for coordinating the research in these diverse fields and for encouraging the necessary contributions from participating countries. The indoor pollutants of most importance have been identified.
