5th AIVC Conference - Reno, US - 1-4 October, 1984
The 5th AIVC Conference - The implementation and effectiveness of air infiltration standards in buildings was held in Reno, Nevada, US, 1-4 October 1984.
Contains 24 papers.
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 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.
Verification of calculation models of air infiltration using three types of test houses. | 1984 | English
In order to verify the calculation models of air infiltration using three wooden test houses which have the same type of construction but have different leakage distributions, airtightness of building components of these three houses were measured
This paper compares the conventional exhaust system with a supply-exhaust system with regard to the possible degree of control of the air exchange in the individual rooms.
Possible health effects and changes in sensation of comfort among tenants after replacement of single glass windows in leaky frames with double glass windows in airtight frames have been studied.
ASHRAE is preparing a standard which addresses the maximum air leakage associated with good construction.
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.
