Demand control ventilation is one of the features that all sustainable buildings should have. Insufficient ventilation usually has negative effects on indoor climate, and it leads to poor inhabitant experience. Some of the repercussions of poor indoor climate include lack of employee productivity, poor inhabitant experience, and tenants’ unhappiness because of the poor ventilation.
There are different types of DCV systems: HRV and MEV. For the MEV system, a central unit is mounted in a cupboard and ducted to extract the polluted air from humid rooms in the house. Since there is no heat recovery, no ducts are required to supply replacement air. For HRV systems, the device ensures your home is healthier, more comfortable, and cleaner since it replaces the stale indoor air with fresh outdoor air.
Although the DCV system has numerous advantages, you should know that excessive ventilation leads to high CO2 production and energy consumption. If the ventilation system is being set manually, it may be hard to maintain ventilation configurations that are balanced. In an instance whereby the occupancy of a building changes regularly, it may be hard to maintain the proper ventilation configurations; this is where the system comes in. The demand control ventilation system has a sequence of well-defined operations, and they can easily save the day.
A DCV is a process that has been designed to reprogram ventilation settings in a building depending on the fluctuating occupancy. The systems can automatically reduce the ventilation intensity based on fluctuating occupancy. The system helps to save a lot of energy while also sensing whether the indoor air is polluted. If the indoor air is polluted, the demand control ventilation system can pump fresh air fast into the building.
Some of the advantages of a demand control ventilation system include:
