National Renewable Energy Lab’s (NREL) Research Support Facility (RSF) a sprawling 326,000-square-foot building housing 1,300 employees is astonishingly the top net-zero energy building in the world. “Net zero” means the building uses no more fossil-fuel-based energy in a year than it makes up for in on-site renewable energy. In all, the RSF has received more than 30 awards for sustainable design and construction.
NREL has chosen Halton Solutions for the ventilation of their kitchen.
The consulting group, William Caruso & Associates had a daunting task when selecting systems and products for the proposed LEED Platinum building for the National Renewable Energy Lab’s employee dining facility.

As part of the design, William Caruso & Associates selected Halton’s Capture Jet exhaust system and M.AR.V.E.L. Facilities Optimization and Resource Management system (FORM). Demand Control Ventilation (DCV) is only one of its capabilities. The combined impact of Capture Jet and M.A.R.V.E.L. on the exhaust and replacement air allows a combined 60% reduction in airflow overall depending on cooking activity. This was an important contribution to the overall reduction of energy use in the kitchen.
The M.A.R.V.E.L. feature allowed hoods to operate independently of each other when tied to a single fan. The ABD’s balancing dampers adjust airflow based on feedback from multiple sensors (duct temperature, space temperature and infrared appliance activity). Since M.A.R.V.E.L. measures exhaust levels at each hood, the output signal for makeup air tracks proportionally keeping the kitchen balanced.
Halton is proud to be a contributor to this project and reducing energy consumption in the largest Net Zero building to date.
