Healthy Buildings with Moderate Enthalpy and Low Pollution Load PDF

Some global recommendations are given for the design of healthy office buildings and assembly halls. New research highlights the importance of controlling the enthalpy of indoor air at a moderate level, i.e., by controlling air temperature and relative humidity at a rather low level, still compatible with thermal comfort. A decrement of air temperature or humidity improves the perceived air quality and may decrease the required ventilation rate. A moderate air temperature and humidity plus individual control by radiation and conduction are recommended in order to decrease complaints caused by individual differences. The building should be acknowledged as a source of pollution, and this source should be minimized during design by the selection of proper building materials and HVAC components. Careful design of air distribution in a space is important for decreasing the risk of draft, which is particularly high at low air temperatures.
