95% kWh and Peak kW Demand Savings Cuts Annual Utility Bill by $59,400
MENLO PARK, CA, May 22, 2013 – Nagle Energy Solutions (NES) announced today that an innovative garage ventilation system it project designed and installed at Oceanview Village, a large, urban development in San Francisco, reduced kilowatt-hour (kWh) consumption by more than 381,000 kWh and peak kilowatt (kW) demand by 44.65 kW – a 95.4% and 95.5% energy savings, respectively, from the property’s baseline consumption.
Engineers for the regional utility verified the savings, noting the garage ventilation system installed by NES cuts the entire, annual electric bill for Oceanview Village by 30% – all while maintaining a 24/7 runtime schedule for all of the property’s garage fan motors. As a result, the cost to ventilate the property’s garage has been reduced by $59,400 a year – from $5,200 per month to just $230 per month or roughly $7.70 a day.
“Nagle Energy Solutions’ detailed measurement and verification methodologies assured us that the retrofit of the Oceanview Village garage ventilation system would achieve substantial energy savings,” said Michael Gollnick, president of the board for the Oceanview Village Homeowners Association (HOA). “The garage project was a key component of the HOA’s sustainability efforts, and NES delivered better-thanpromised results, so we’re quite pleased.”
A $62,000 investment by the HOA in the carbon monoxide (CO) sensor-based, demand-control ventilation (DCV) system installed by NES possesses a net present value (NPV) of $672,000 and provides a minimum cash inflow of $830,000 throughout the 15 year life of the system.
The system utilizes a proprietary, smart-control logic that detects and measures vehicle fumes in the garage space and then modulates fan speeds to prevent CO levels from exceeding a pre-defined set point (measured in parts per million) for extended periods of time. The result is to consistently achieve energy savings up to and beyond 95%, while ensuring the health and safety of building occupants and visitors by providing continuous ventilation.
Oceanview Village houses a two-level, 144,500-square-foot, enclosed parking garage for its residents and visitors, accommodating 450-plus automobiles. The garage ventilation system is comprised of four, 10-horsepower (HP) exhaust fans, two, 7.5-HP supply fans and two, 3-HP exhaust fans.
