Energy

ENERGY conservation depends greatly on how well building heating, ventilation and air conditioning (HVAC) systems are controlled while matching occupant needs. In recent years, Direct Digital Control (DDC) systems, which can easily and accurately control building HVAC systems, have become so cost-effective that they are replacing manual and electromechanical controls in retrofits, and are also being installed in almost all new buildings.

Minimizing the amount of energy used requires strategic methods of controlling the building air systems.

To employ these methods, systems should be equipped with an air quality (CO2) sensor, space temperature and humidity sensors installed in various locations, outdoor air temperature and humidity sensor and occupancy sensors that can feed signals back to the central control system.
