Due to the complexity in describing the simultaneous effects of a number of factors that influence the climate of an attic space it has proven to be difficult to make simulations of it.
Energy savings by balanced ventilation with heat recovery and ground heat exchanger. | 1992 | English
This paper investigates quantitatively the energy conservation achieved by balanced ventilation with heat recovery and upstream ground heat exchanger.
Good indoor air quality in buildings becomes such a major concern that new design recommendations emerge in many countries (USA, Nordic Countries,...).
Energy saving and CO2 reduction. The German CO2 reduction programme and the requirements to be met by the building equipment technologies. | 1992 | English
The greenhouse effect is one of those topics in environmental politics which are currently worldwide at stake. There are several national concepts aiming at the diminution of CO2-emission in order to lessen the greenhouse effect.
Indoor ozone concentrations: ventilation rate impacts and mechanisms of outdoor concentration attenuation. | 1992 | English
The classification of outdoor (ambient) air as fresh for the purposes of ventilation is not always appropriate, particularly in urban areas.
By means of parametric analyses, the paper describes how the "constantness" of a Constant Air Volume system is affected by temperature differences resulting from heat load variations or otherwise. Several design related parameters are considered.
A heat recovery system reclaims heat from outgoing stale air, supplying it to incoming fresh air.
Improved indoor environment and ventilation in schools. A case study in Vaxjo, Sweden. | 1992 | English
During the last decade several surveys in Sweden have indicated that the indoor climate in existing schools is unsatisfactory, therefore a thorough project was carried out in Växjö).
The penetration of gaseous pollutants into buildings in the case of a sudden contamination of the outdoor air. | 1992 | English
A sudden contamination of the outdoor air by some toxic gas can have several causes. The primary goal of the investigation was to determine the protection afforded by sheltering indoors.
Occupant's behavior with respect to window opening: a technical and sociological study. | 1992 | English
The occupant's behavior with respect to window opening may greatly affect the ventilation system, the energy consumption orland the indoor air quality.
This report presents the results from the registration throughout a month of relative humidity, temperature and outdoor air exchange as well as the concentration of carbon dioxide in each room of an inhabited single family house, in which all room
Fluctuating airflow thorough buildings is caused by temporal and spatial variations of wind-induced pressures around building envelopes, and include pulsating airflow and eddy penetrations.
The present paper reports on tracer gas measurements performed in five large buildings during normal operating conditions. In all buildings air was supplied through ceiling diffusers and returned through a ceiling plenum.
Odour threshold of kitchen exhaust air during typical costing situations in a dwelling. | 1992 | English
The dour threshold value of kitchen exhaust air was experimentally determined during typical cooking situations and tobacco smoking in a dwelling. During cooking, air from the exhaust duct was taken into a sample bag.
Ventilation systems in dwellings should not only maintain the quality of the air, in other words limit pollutant concentration whatever the origin, but protect the structure, that is, limit condensation and the storage of excessive humidity in exi
Energy recovery in ventilation systems: a worldwide energy saving and environmental protection technology. | 1992 | English
For more than 20 years, energy recovery systems have been operated successfully in European countries in comfort and industrial ventilation systems in order to reduce the heating and cooling capacity as well as to reduce the annual energy consumpt
Healthy building: an energy efficient air conditioned office with good indoor air quality. | 1992 | English
The NORWEB Headquarters in Manchester, UK, is an air conditioned energy efficient office building of unusual design, completed in 1988. It has three stories with overhanging canopies providing solar shading and 21 % solar control glazing.
Contaminant dispersal measurement using laser light sheet illumination and digital image processing techniques. | 1992 | English
This paper describes a method for measuring tbe dispersal of airborne contaminants by light-sheet illumination of aerosol tracen and digital image processing techniques.
Impact of subslab ventilation technique on residential ventilation rate and energy costs. | 1992 | English
Radon is the largest source of risk to human health caused by an indoor pollutant, at least in the industrial countries.
