Volume content
5th AIC Conference: The implementation and effectiveness of air infiltration standards in buildings (Book of Proceedings) | 1984 | English
This paper discusses the situation in the Netherlands with respect to air tightness of dwellings and reflects discussions about this in the Dutch Standard Committee on Air Tightness of Buildings.
A reduction of infiltration and ventilation rates by a mere 1% would reduce annual US energy costs by about 300 million dollars.
Airtightness and wall construction in prefabricated Swedish single family houses, 1984. | 1984 | English
This survey describes how external walls and joints are constructed in practice.
The air tightness of 15 detached houses was measured firstly immediately after erection and secondly after a period of 1.5 to 4.5 years. All the houses were timber framed ones, equipped with mechanical ventilation systems.
In Finland there are not yet any regulations or standards concerning the airtightness of buildings.
In 1981 Norwegian building regulations introduced quantitative requirements to air leakages in different types of buildings.
The air infiltration associated with ventilation in buildings is recognized in ASHRAE Standard 62-1981, Ventilation for Acceptable Indoor Air Quality.
Increased attention to the reduction of energy consumption in buildings and greater awareness of the need to maintain acceptable standards of indoor air quality have led to the development of new or revised standards of building airtightness and v
Development of occupancy-related ventilation control for Brunel University Library. | 1984 | English
A microprocessor system is being developed for occupancy related ventilation control of mechanical ventilation in Brunel University Library.
The relation between air infiltration rate and indoor concentrations of radon gas, radon daughters, and formaldehyde has been investigated for both summer and winter conditions in a number of Toronto houses with low rates of natural ventilation.
Ventilation standards in buildings are receiving increased attention because of energy conservation and indoor air quality.
Reduction of fresh air ventilation is becoming the major means of energy conservation in office buildings.
Energy performance standards regarding air infiltration of buildings in Switzerland. | 1984 | English
The Swiss performance standard for energy conservation in buildings SIA 380/1 is explained. This standard leaves air infiltration and other detail decisions to planners if minimum performance levels are met.
Since 1970 measurements of air change rate have been carried out in about one thousand buildings by the Swedish Institute for Building Research (SIB). In this paper we present results from these measurements.
The situation in Canada with regard to building regulations affecting the airtightness of buildings is reviewed with emphasis on a new standard test method for measuring airtightness which departs somewhat from methods used inother countries.
Air change rates were measured in one two-storey detached house with five basic types of passive ventilation systems: an intake vent in the basement wall, an outdoor air supply ducted to the existing forced air heating system, an exhaust stack ext
Air infiltration typically accounts for a third of the energy loss in a heated building. The driving forces for natural air infiltration are wind and temperature differences.
Eleven countries are cooperating to establish guidelines for minimum ventilation rates which are sufficiently large to meet the demand for outdoor air in buildings without unnecessarily wasting energy.
