Much like air for venting heating and cooling systems, Variable Air Volume (VAV) diffuses vents to accommodate endless heating and cooling. Sensors help detect temperature and occupancy changes to aid in maintaining an optimal comfort zone. Due to ease of control and computation, apportioned VAV diffusers work marvelously in large commercial apartments and institutional centres. By construction, VAV elevators provide sectional dynamical adjustments which save energy, aid in controlling cramped for space ventilation systems, control efficacy, and improves comfort. This complements usage in large sales buildings by institutional complexes
