A case study provided by Bonneville Power Administration in the Pacific Northwest, described how a small retailer retrofitted 2 rooftop packaged HVAC units with a new efficiency technology and was able to save over 24,000 kWh (a 45% reduction) per year.
Similar results were identified in another 12-month field test at malls, grocery stores, offices and other commercial buildings throught out the US.
This technology, from Transformative Wave, is called CATALYST and it combines conventional energy saving measures with new innovative fan controls in an easy-to-implement device for single zone rooftop units.
PG&E and SMUD have both acknowledged the accuracy of the savings from this new technology and are providing incentives to customers who retrofit their HVAC systems. The incentives for PG&E are based on HVAC tons (as high as $194/ton) and the SMUD incentives are currently based on kWh saved ($0.08 per kWh).
