Tip for Building Efficiency

August 31, 2015

Ventilation air can constitute a large portion of an overall energy bill. In some buildings, it can be as high as 30% of the cooling load and 60% of the heating load. Are you finding your energy bills to be too high?

One way Egan can help you reduce this cost is to employ Demand-Controlled Ventilation (DCV) through your building automation system. A DCV system can be retrofitted to a building or utilized in new construction.

A DCV system uses carbon-dioxide sensors located within the building. These sensors are used to estimate the minimum ventilation requirements needed for occupants. If carbon dioxide levels rise—and they will as more people enter the space—the ventilation system opens and allows fresh air to enter for proper ventilation.

Utilizing a DCV system yields a huge potential for energy savings, especially in building zones where occupancy levels vary widely. When occupancy levels are low, the outdoor ventilation rate can be reduced to minimal levels and eliminate the need to condition additional outdoor air. Building zones such as auditoriums and conference rooms are prime examples.
