    For the design of healthy buildings with a comfortable indoor environment, some general recommendations are provided. 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 is 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. To improve ventilation effctiveness, supply of air close to the breathing zone of each individual should be considered. Low air velocities in the occupied zone are required in order to decrease the risk of draught, which is particularly high at low air temperatures.
