Likewise, people ask, how does demand control ventilation work?
The ventilation system must constantly draw outdoor air to keep a suitable air quality, but this air reaches high temperatures during summer. DCV reduces the amount of warm air moving into the building, which saves on air conditioning. Some climate zones are suitable for an airside economizer.
