In total there are approximately 125 units, ranging from small compact ventilation to large ventilation with avfukterenheter / air conditioning with Central Operations Monitoring System (BMS), to simple construction with only supply and exhaust fans mounted in the wall / ceiling. The largest sports facilities have several different ventilation systems serving one or several specific rooms or areas / arealer.Ventilasjonsanleggene the agency's buildings are in need of service and maintenance 2 times per year (every 6 months). BymiljAetaten technical personnel have not enough capacity to perform these services and maintenance themselves.

Out and interior ventilation grills / covers cleaned (vacuumed) once a year.
