New and Underutilized Technology: Demand Control Ventilation for Commercial Kitchen Hoods

The following information outlines key deployment considerations for demand control ventilation for commercial kitchen hoods within the Federal sector.

Benefits

Demand control ventilation for commercial kitchen hoods optimizes energy efficiency by reducing the exhaust and MUA fan speed. This is accomplished by leveraging sensors to determine the minimum amount of exhaust air required to capture and contain effluent from the cook line.

Application

Demand control ventilation for commercial kitchen hoods is applicable in hospital, school, prison, housing, service, and other facilities with large kitchen facilities.

Key Factors for Deployment

With demand control ventilation for commercial kitchen hoods, overall building air must be maintained. Savings are due to a reduction in blower energy, but also potential savings from reduced heating and cooling.

Ranking Criteria

Federal energy savings, cost-effectiveness, and probability of success are ranked 0-5 with 0 representing the lowest ranking and 5 representing the highest ranking. The weighted score is ranked 0-100 with 0 representing the lowest ranking and 100 representing the highest ranking.
