DSMEA was retained by Grenadier Realty Corporation to conduct Local Law 87 (LL87) Energy Efficiency Reporting for Newport Gardens, a residential community in Brooklyn. The audit and analysis identified several significant retro-comissioning (RCx) and energy conservation (EC) measures that could be taken by the building to reduce energy costs and result in a much higher performing facility. Newport Gardens comprises eight individual buildings located across two separate tax lots; each building is three-stories tall, and operates independently of all other buildings on the property. Having multiple buildings spread across two separate lots is not a typical configuration for LL87, so DSMEA’s experience and adaptability proved especially vital in producing comprehensive energy conservation strategies and measures for Newport Gardens.
The first set of energy saving measures DSMEA recommended to Newport Gardens were the retro-commissioning measures, or RCx measures. These are measures that are taken to ensure code compliance and approve upon existing equipment within the facility; the RCx measures included:
It was also recommended to the building that the outdoor sensors used to control the boiler reset be relocated to the northern face of the building, to reduce the chance of false temperature readings occurring.
The next set of energy saving measures DSMEA recommended were the Energy Conservation Measures, or ECMs. These are measures that require capital investment from the facility to yield energy savings, and are not required to be completed by LL87. In Newport Gardens case, the majority of energy savings derived in our analysis came from the implementation of ECMs, which include:
