A platform for research: civil engineering, architecture and urbanism
The author reviews research in Finland into control of ventilation and air quality. Among the conclusions is that airtightness of new small houses can deteriorate by up to 10 per cent after one year, and that it is difficult to control air supply intake through the building envelope. New proposals for leakage factors are presented, together with experiences of newer warm air heating with mechanical ventilation and heat recovery. For practical purposes, an internal underpressure (higher exhaust rate than supply air flow) is often preferable.
