The influence of specific ventilation rate on the emissions from construction products.

Very little experimental data exist validating the influence of temperature, ventilation  rate, air velocity, humidity and adsorbed pollutants from other sources on emission rates from construction products. Experiments were performed using small scale climate chambers including the new CLIMPAQ quantifying emissions from test specimens of linoleum, acrylic paint, nylon carpet, and sealant. A trained sensory panel voted on the decipol scale and chemical analysis identified and quantified the major pollutants after the specimens had been conditioned in the chambers for six days.

Ventilation rates and air tightness levels in the Swedish housing stock.

This paper reports results from the ventilation and air tightness measurements in Swedish dwellings as part of the 1992 Swedish Energy and Indoor Climate Survey (the ELIBstudy). The indoor climate in a random sample of 1200 single- and multi-family houses from the Swedish housing stock were investigated. Among different parameters the ventilation and the air-tightness of the houses were measured.

The Variation of Heat Loss Through Suspended Floors with Ventilation Rate.

Increases in the levels of thermal insulation required in the walls and roofs of houses in the U.K. in recent years have meant that heat losses through floors now assume greater significance, as a proportion of the total heat loss from a dwelling. To effect further reductions in the energy consumption of houses, the thermal performance of floors needs to be examined to assess the most cost effective insulation strategy.
