Contains 12 papers.
4th AIC Conference: Air infiltration reduction in existing buildings (Book of Proceedings) | 1983 | English
Reviews air infiltration studies in New Zealand. Tighter houses have evolved over the years through changes in building methods and materials. Some of the tighter houses can have condensation problems.
Describes the testing of 8 federal office buildings (size from 3000 sq.m.
Describes pressurization tests conducted by the National Testing Institute on 3 large industrial buildings.
Performs tracer gas measurements and fan pressurization experiments on an 8-storied student residential building in order to determine the influence of wind as well as of stack effect upon air infiltration.
Compares and contrasts different methods of ventilation measurement in large buildings. Conventional methods of using tracer gas to measure ventilation rates in large volumes are cumbersome and expensive.
Measures the airtightness of various types of 25 residential units (9 detached houses and 16 apartments) using the fan pressurization technique.
Ventilation rates and inter cell air flow rates in a naturally ventilated office building. | 1983 | English
Determines ventilation rates and intercell flow rates in naturally ventilated office building using multiple tracer gases. Subdivides the building into 3zones and seeds each zone individually with a different tracer gas.
Describes the retrofitting of a 14-storey office block in Oslo, done as part of an energy conservation project carried out in Norway 1979-82.
Retrofit planning tools for institutional and residential buildings with user influenced air infiltration. | 1983 | English
States that methods used by Swiss energy consultants in calculating air change rates are often inaccurate. Most consultants use the "observation method" utilising smoke pencils etc.
A short treatment of the concepts and aspects that play a role in ventilation is followed by a brief description of the investigation methods employed. Gives a concise survey of the equipment and mathematical models used.
Reviews the published data on component air leakage, and from this compiles a set of component leakage figures for use in estimating leakage areas and their distribution in buildings.
