Energy saving measures in the area of ventilation. Energiebesparande atgarder inom ventilationsomradet.

Explains possibilities of saving energy in the area of ventilation. Summarises fundamental theories for calculating air flow through building leaks, ventilators and fan systems which are put in their total context - wind, temperature, air leakage, intentional ventilation, building technology, energy requirements. Treats factors which influence ventilation requirements. Compares results from field studies of actual air change rates with the requirements of Swedish Building Standard 1980.
