LoginThe 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.
10th AIVC Conference - Espoo, Finland - 25-28 September 1989
The 10th AIVC Conference - Progress and trends in air infiltration and ventilation research, was held in Espoo, Finland, 25-28 September 1989.
Contains 52 papers.
Volume content
During the past decade a multitude of diagnostic procedures associated with the evaluation of air infiltration and air leakage sites have been developed.
A modern concept for office buildings: energy saving and good indoor climate are no longer contradictory. | 1989 | English
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.
This paper describes a simulation program which was developed for the modelling of air-conditioning systems and conditioned spaces in industrial buildings.
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.
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.
This paper describes tracer gas methods and equipment developed to measure infiltration and inter-zone air flow rates in New Zealand houses.
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.
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.
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.
