ventilation requirements

Besides the hygienic aspect, also the aspect of energy saving of heating residential buildings is very important. This is only possible by mechanical ventilation with heat recovery. This paper describes a part of the large variety of systems, which are nowadays available on themarket. The main difference of these systems are: * single room unit/decentral unit and * central unit for one dwelling or a single family building.

This document reports on the result of an opinion survey of the residential ventilation industry which was conducted in August of 1988.

The series of technical publications 'Energy Efficiency in Buildings' was introduced by British Gas during the International Energy Conservation Month, October 1979, as part of the industry's support of Government energy initiatives. The publications consist of a compilation of technical studies mainly prepared by the staff of British Gas Watson House Research Station. The aim of 'Energy Efficiency in Buildings' is to contribute to the training and development of those concerned with building design and the efficient use of fuel.
