Canadian research into residential ventilation and combustion venting revealed that the installed performance of exhaust equipment, ducting passages, and site-built chimneys was largely unknown.
Fugler D
The paper compares air infiltration rate measurements with air leakage measurements in a modem industrial building.
Jones P J, Powell G
This paper explores the results of air infiltration and ventilation research carried out in Canada over the last decade and specifically examines its application to low-rise residential buildings.
Riley M, Lawton M
In order to be validated, the computer programs simulating the air flows in multizone buildings need several measured data sets to be compared with. Such a set was measured on the LESO, a mid-sized administrative building.
Furbringer J M, Compagnon R, Roulet C A, Gadilhe A
1979 a project was launched at Technological Institute, Copenhagen with the purpose of developing a method for continuous measurement of air change rates in occupied dwellings.
Kvisgaard B, Collet P F
In central units of air heating systems the supply air flow must meet the actual heating demand. Most of central units for air heating systems have only one fan , which is designed for the maximum air flow at the maximum heating capacity .
Steimle F, Glimpel T
The air exfiltration part of ventilation is often difficult to determine and its part of the energy balance is therefore usually determined as a remainder or given a constant value.
Blomsterberg A
This paper presents a new technique for supply of outdoor air directly through external walls into a dwelling room without any draught problems.
Werner G
This paper presents and evaluates a new method, based upon tracer gas techniques, for determining interzonal airflows and effective volumes in a multizone enclosure.
O'Neill P J, Crawford R R
This paper examines some designs which lead to indoor air pollution and exhorts mandatory maintenance of all building services which determine the health and safety of the building occupants as anintegral part of our city bylaws.
Ferahian R H
A tracer gas technique for determining volumes and air flow rates in multi-cell systems with a single tracer gas is considered.
Hedin B
The climatical conditions in Sweden are such that it has almost always been necessary to tighten the houses quite thoroughly in order to avoid cold-draught and to make as good use of the heating as possible.
Kronvall J
During the past decade a multitude of diagnostic procedures associated with the evaluation of air infiltration and air leakage sites have been developed.
Harrje D T, Gadsby K
An up-to-date design concept for office buildings results in a very low energy consumption and provides a better indoor climate at the same time.
Braun W
The use of passive perfluorocarbon technique for air flow measurements has been developed and tested. The building and testing of the system took approximately one year. The reproducibility of the analysis was tested during the period.
Sateri J, Jyske P, Majanen A, Seppanen O
A test room with a Displacement Ventilation System has been built. Air velocity and temperature profiles were measured at different places in the room under summer and winter conditions.
Kegel B, Schulz U W
This paper describes a simulation program which was developed for the modelling of air-conditioning systems and conditioned spaces in industrial buildings.
Heikkinen L
This paper describes tracer gas methods and equipment developed to measure infiltration and inter-zone air flow rates in New Zealand houses.
Bassett M R, Beckert H M
Moisture and mould in buildings have become fairly common problems in Italy, particularly since regulations aimed at energy conservation have been enforced in the seventies.
Aghemo C, Lombardi C, Masoero M
Ventilation in a building enables to renew the air it contains by means of a natural exchange of air (depending on weather conditions and climate) or a forced exchange using mechanical appliances.
