1. Demand Controlled Ventilation for Commercial Kitchens 

Current industry practice is manually controlled fans – most are single-speed motors which are left running for long hours. Demand ventilation systems vary the speed of the motors to provide only the amount of ventilation actually needed.  Click here to read more... 

2. Advanced Design Rooftop HVAC Unit

The Advanced Design Rooftop HVAC Unit offers improved energy performance over the typical "commercial" rooftop unit by enhancing the performance of individual components and configurations, including fans, coils, filters, dampers, compressors, condensers, controls, and airflow path.  Click here to read more...

3. Air-side Economizers for Data Centers

Install 100% outside-air cooling capability in a data center to provide free cooling where  outside air was previously provided only for satisfying the minimum ventilation requiremen ts. Because data centers require air conditioning year-ro und, significant energy savings are realized by using outside air for free cooling.  Click here to read more...

4. Demand Controlled Ventilation

Ventilation can be one of the top energy uses in a high occupancy building. Spaces  designed for large numbers of people are required by code to have HVAC systems that can provide large amounts of outside air. However, these spaces are frequently only partially occupied or are unoccupied. DCV represents an untapped potential source of energy savings for existing buildings and an excellent investment in new buildings.  Click here to read more...
