The Village at Oak Hill Plainville, Mass..

10-year-old, 46-unit townhouse complex located in a quiet, well-maintained neighborhood in Plainville, Massachusetts.

In its capacity as a Mass Save® Multi-Family Retrofit Program vendor, RISE Engineering conducted a free onsite evaluation of this development’s street lights and residential units and provided a proposal identifying recommended energy efficiency improvements, project costs, financial incentives, and estimated energy savings. RISE subsequently arranged professional installation of agreed-upon measures and coordinated the incentives with the utilities.  Even though this development is relatively new, these natural gas and electric energy upgrades are projected to reduce the condominium association’s and unit owners’ aggregate energy costs by $15,000 annually and by $229,000 over the lifetime of the installed measures.
