Perrysburg School Gym Using DimOnOff's
DimOnOff lighting controls, enabled by EnOcean's energy harvesting wireless technologies, disrupted the status quo by provided alarming reductions in energy consumption at a junior high school in Perrysburg, OH. The retrofitted system disposed of energy inefficient lighting and replaced controls and fixtures - proving again that extraordinary results can be achieved by simple means. Using only existing wires, system integrators replaced the inefficient single-zone system and created custom lighting scenarios for the school. The school's lighting system was upgraded overnight in an 8-hour span without having to run new wires or shutdown the gym at any point. Classic retrofit installation barriers, such as wiring constraints and concrete walls, were overcome by DimOnOff's innovative hybrid approach to lighting. The solution combines DimOnOff's powerline-system with energy harvesting and wireless performances enabled by EnOcean.
The post-installation results were extensive; a reduction in energy consumption was noted immediately, expanded multi-zone lighting was established, lighting quality was improved, and several Ohio-state sustainability tax incentives were achieved, amounting to a yearly savings of at least $5,000. The upgraded system includes 8 zones of lighting. The wireless energy harvesting controls immediately extended the flexibility of the system. Low level lighting is used during gym classes, while high output is reserved for sports events. When lighting scenarios change, modifications or additions can be easily made via laptop or web access.
Tax Incentives and Sustainability Paybacks Provide Exponential Return on Investment The State of Ohio provides large tax incentives for sustainable school buildings. Utility energy efficiency incentives offer rebates as high as $145 per fixture. In addition, the retrofit qualified the school for the HB264 Energy Conservation Measure providing additional incentives. With the use of wireless technology, the gymnasium's installation tax incentives and sustainability paybacks amounted to a total savings of more than $5,000 annually.
