The main goal of a research project on wind barriers was to get more information about the influence of wind pressure on the heat loss from wood frame constructions.

When carrying out pressure tests of models of multi-story buildings in The Boundary Layer Wind Tunnel, the external mean and RMS pressures are measured at 400 to 800 different locations over the building surface.

All the findings about indoor air quality is of little use to the average citizen, if they are not applied and and translated into rules incorporated in our building codes for the design, construction, and last but certainly not least maintenance
Ferahian R H
The National Bureau of Standards has undertaken a research effort to develop a general air quality simulation program for buildings.
Grot R, Axley J
Laboratory measurements have shown that when pressure differences are applied across wall and roof elements, the majority of the pressure drop takes place across the vapour barrier .
Brunsell J T
This paper presents results of air leakage measurements on brick walls and concrete block walls, used as outer or inner leaf of a cavity wall. The results are obtained using a pressure box on a series of test walls.
Lecompte J G N
The concern that a large number of housing units across Canada, and in particular, through Atlantic Canada are exposed to potential damage from wood rot due to moisture trapped within exterior walls caused a joint task force of Canada Mortgage and

The 'Simplified Technique' is a method by which it is possible to determine approximately the infiltration and ventilation rates of large and complex buildings. The aim is to provide a reliable and easy-to-use procedure for non-specialists.
Perera M D A E S, Walker R R, Prior J J
Summary of papers in the Proceedings of the Eighth AIVC Conference. Headings include measurement techniques, calculation techniques, design (control of the internal environment) and the positive aspects of ventilation and infiltration.
Holmes M J
Measurements in some dwellings show differences of the absolute humidity as a function of the kind of ventilation (only natural or mechanical exhaust air or balanced ventilation) and the position of the single rooms, especially of the bedrooms.

DAMP is an 'Expert System' or 'Knowledge Based System' (KBS) to aid diagnosis of causes of moisture damage found in buildings in New Zealand.
Trethowen H A
In this paper the moisture-diagnosis prototype of a knowledge based expert system to assist in the identification and diagnosis of air leakage problems in residential buildings is described and discussed.
Persily A K
The CO2-concentration of room air provides an indicator for the air quality in spaces without smokers. A classroom with mechanical ventilation has been evaluated for eighteen months using such a technique.
Baumgartner T, Bruhwiler D
This paper presents and discusses results of moisture transfer into timber frame constructions. The two mechanisms of transfer are diffusion and bulk air movement.
Dudek S J M, Valentine G
In the past years the need has grown for a sensitive flowrate meter with a very low pressure drop. Such a device can be used to measure flowrates of airflows through the grilles of mechanical ventilation systems with low duct pressures.
Phaff H
The accuracy of tracer gas measurements of building air infiltration rates has been a widely discussed topic.
Bohac D L, Harrje D T, Horner G S
The mixing system (even called the dilution system) is normally used throughout the world to supply air to a premises. In the mixing system you blow air at high velocity into the room at a temperature which gives you the wanted room temperature.
Horz T, Danielsson P O
The constant concentration tracer gas (CCTG) technique is typically used to measure air infiltration rates in mulitzone buildings.
