8th AIVC Conference: Ventilation technology research and application (Book of Proceedings) | 1987 | English
Simplified technique for measuring infiltration and ventilation rates in large and complex buildings: protocol and measurements. | 1987 | English
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.
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.
Ventilation technology - aims of the Federal Ministry for Research and Technology in Research and Application - Keynote speech. | 1987 | English
The Keynote speech gives a general outline of developments in the field.
The moisture load in dwellings as a function of the layout of the rooms shown by ground plans. | 1987 | English
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.
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.
DAMP is an 'Expert System' or 'Knowledge Based System' (KBS) to aid diagnosis of causes of moisture damage found in buildings in New Zealand.
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.
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.
This paper presents and discusses results of moisture transfer into timber frame constructions. The two mechanisms of transfer are diffusion and bulk air movement.
Field study comparisons of constant concentration and PFT infiltration measurements. | 1987 | English
The accuracy of tracer gas measurements of building air infiltration rates has been a widely discussed topic.
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.
The use of modified constant concentration techniques to measure infiltration and interzone air flow rates. | 1987 | English
The constant concentration tracer gas (CCTG) technique is typically used to measure air infiltration rates in mulitzone buildings.
Evaluation through field measurements of BNL/AIMS, a multiple tracer gas technique for determining air infiltration rates. | 1987 | English
Brookhaven National Laboratory (BNL) in the USA has developed a multiple tracergas technique called BNL/AIMS (Air Infiltration Measurement System) for determination of air infiltration rates.
Rising moisture from the ground has caused quite a lot of damage on foundations of Swedish buildings, in particular for the type concrete slab on the ground.
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.
The National Bureau of Standards has undertaken a research effort to develop a general air quality simulation program for buildings.
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
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 .
