The house dust mite inhabits bedding and soft furnishings in homes. It is implicated as a major cause of allergic asthma. Maintenance of indoor humidity below a level of 7 g/kg inhibits the growth of the mite population.
A prototype of a low cost, low energy office building was built using a new Finnish component system building technology.
The ventilation rate in a building depends on many things, one of which is the air temperature. The air temperature in turn depends in part on the ventilation rate.
The purpose of this study was to carry out a mathematical modelling analysis of the effect of indoor pollutant source strengths and ventilation rates on the concentration of pollutants.
The study deals with the theoretical and experimental simulation of gas leaks in buildings.
The amounts, quality and factors affecting of dust accumulation in supply air ducts of eight nonindustrial buildings were studied.
In well insulated buildings the ventilation heat is sometimes higher than the heat losses by transmission. For a air change rate of 0,8 per hour the specific heat flux must be calculated with 25 w/m², so heat recovery can save some energy.
Draughts due to air inlets are one of the problems to be solved for improving the global performance of mechanical ventilation systems.
This paper reports the results of humidity and ventilation measurements in occupied residential buildings to study the effect of airborne moisture movement on condensation risks.
Avery largeelectronics factory had beencompletely refurbished, and new mechanical ventilation systems installed.
A humidity controlled exhaust fan have been tested during the winter season 1991/2. The test have been carried out in a detached one storey house with a flat roof.
A new method for linking results of detailed air flow pattern calculation with multizone models. | 1992 | English
Multi-zone models are a common tool for calculating air and contaminant exchange within rooms of a building and between building and outdoors.
The new building and HVAC technology was used when an EBES multistorey residential building was built in Helsinki.
Improved ventilation combined with energy efficiency in naturally ventilated houses. | 1992 | English
Modern one-family houses in Scandinavia built before 1980 are often naturally ventilated and heated by electric baseboard heaters. The overall supply of fresh air is often inadequate during the heating season in many of these houses.
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.
This paper deals with the problem of the weather influence on ventilation rate for naturally ventilated buildings with purpose provided openings and vertical shafts.
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.
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.
