LoginIn 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.

Wind and pressure requirements for the validation of a multizone air air infiltration program. | 1989 | English
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.
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.
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.
This paper presents a new technique for supply of outdoor air directly through external walls into a dwelling room without any draught problems.
New design of central units in air heating systems for heating and ventilation in domestic buildings. | 1989 | English
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 .
Multizone flow analysis and zone selection using a new pulsed tracer gas technique. | 1989 | English
This paper presents and evaluates a new method, based upon tracer gas techniques, for determining interzonal airflows and effective volumes in a multizone enclosure.
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.
A tracer gas technique for determining volumes and air flow rates in multi-cell systems with a single tracer gas is considered.
What does the designer of a future energy-efficient building ask of the air flow specialist? - Static predictions of air flow patterns and optimization of thermal comfort and indoor air quality at design conditions will not be enough for him.
Annex 14 -Condensation and Energy- started in April 1987, with a take of meeting in Utrecht, The Netherlands. The annex itself was born after a moisture-workshop in September 1985 at the Laboratory of Building Physics, KULeuven, Belgium.
Tracer gas techniques have become widely used to measure the ventilation rates in buildings.
The IEA Annex 18 Demand Controlled Ventilating Systems-(DCV-Systems) with 9 participants are just in the middle of the work.
