Ventilation and air-conditioning
Proper ventilation and air-conditioning mean a pleasant working environment, and may be required by law. People work more efficiently if they are neither too hot nor too cold. And air-conditioning is becoming increasingly common in private houses and flats.
Energy-efficient buildings often require precise ventilation in order to deliver the low energy use and high insulation values promised. Ventilation also can mean smoke extraction systems, which are often legally required.
