Air management in residential or tertiary usage buildings constitutes one of the key points of energy control in buildings. The principle themes concerning air management are heating or air conditioning, and ventilation and air renewal, mechani

Approximately 40% of the energy consumption in Sweden is utilized in the heating of buildings. In order to reduce the amount of energy utilized for heating purposes, more stringent thermal insulation requirements for buildings were introduced.

Indoor air quality is regarded as the single most important health issue facing us in the 1980's. The total number of serious health effects related to IAQ in non- industrial buildings have been miniscule compared to the total building stock.

Resulting from experiences of a project by the German National Energy Research Foundation (NEFF), and further investigations, a recommendation is presented on the permeability of building envelopes in residential buildings, according to on hand ventilation devices. To find out the permeability, the air leakage at 50 Pa is evaluated. This can be found out with the differentiated pressure reading of the building.

Indoor air pollution is particularly noticeable today, resulting from the improvement of ventilation in building envelopes in order to economise in heat energy, and the consequent reduction of fresh air entry, leading to poorer air quality. The article describes the effect of tobacco smoke on the indoor climate of residential and office buildings and its effects on health, particularly its effect on non- smokers, or the passive effects of smoke.

A benchmark study by Geomet Technologies, Inc, is developing data on the air quality effects of weatherizing a home. One effort under this study has bee nhas been an experiment carefully designed to quantify the relationships between the thr

Since 1973 there has been greater emphasis in Sweden on energy production and energy saving, but the products have often been of dubious design or benefit, and too expensive to be applied to normal residential Scandinavian housing. The economic

Indoor air pollution is defined, and some of the causes are listed, all of which can be harmful to health. The problem is accentuated by recent insulation measures aimed at economising on energy costs, which lead to a dramatic reduction in natu

This paper describes the numerical analysis of room air distribution by the finite element method which can easily deal with any domain, the boundary conditions and so on. 

The article discusses how far the builder is to blame for condensation and its subsequent problems of mould growth. The UK Building Regulations of 1985 for ventilation and condensation do not go far enough in discouraging inadequate forms of
