INTEGRATION OF ENERGY MANAGEMENT, ELECTRICAL SUBMETERING AND TIME SENSITIVE PRICING IN A LARGE RESIDENTIAL COMMUNITY UTILIZING WIRELESS COMMUNICATIONS

摘要

In this paper, we present the second phase of a demonstration project in which advanced metering and communications technology, time-sensitive pricing, sensors and control systems were combined cost-effectively in a unique way to enable multifamily apartment residents, owners, the utility grid and society to achieve reduced energy consumption and demand, and take full advantage of incentives available from NYSERDA programs. Along the way, a number of significant barriers were overcome. Specifically, the project involves a 37 building garden apartment complex covering over 60 acres in Queens, New York, where a project team of consultants and technology vendors integrated an advanced 2-way wireless data communications system, electrical submetering, a 3-period time-of-use rate, apartment temperature sensors, boiler control and room air conditioner controls. The installation addressed the unique barriers of garden apartment complexes by consolidating data from all 930 individual apartments and 33 utility master-meters. In addition, the apartment meters use a color-coded LED display to inform residents of the TOU price period, temperature sensors transmit information to the boiler control system and integrated controls enable control of room air conditioner units during hot summer days. Original projected reductions in apartment sector electric consumption and demand were 20% and in overall building heating fuel consumption at 10%. Actual results will be documented in this paper. Additional incentives are also anticipated from NYISO for demand response activities, such as critical day load curtailments. This NYSERDA project is serving as a model for integrating multiple energy and demand reduction measures in multifamily buildings, especially garden apartment complexes, which have entailed significant barriers to energy savings measures, particularly electrical submetering, in the past.
