The New York Design Center (NYDC)is a luxury furniture showroom building located inManhattan's Midtown East area. World Class furniture designers make up the tenant roster for this building where they can collaborate and provide a centralized market for designers, architects and purveyors of luxury and functional home furnishings. The NYDC has been actively leading the energy efficiency improvement and sustainability of its building since the movement began and serves as a role model for other commercial landlords.
In 2013/2014 NYDC's building-wide LEDconversion initiative included tenant spaces as well as common areas and has netted a permanent demand reduction of 300 kW annually. From a facility services standpoint, this required removal of ducted central airconditioning systems and replaced with ductless split air conditioning units manufactured by Daikin. The result was over 128 mutually exclusive airconditioning systems that provided excellent temperature and humidity control however from a whole building point of view, the equipment operated sporadically which contributed to a volatile kW demand profile and low loadfactor. These conditions further resulted in less than favorable supply prices and undue stress on building electrical systems. NYDC engaged LC Associates and PEPCO to evaluate potential alternatives to the existing condition and after modeling several options it was concluded that the most cost effective means and methods available was to deploy a building wide energy management system and take advantage of the ConEdison/NYSERDA Demand Management Program which offered incentives to lower and "manage" kW demand of buildings. LC Associates led a team of ConEdison Market Partners i.e. the "Green Team", who collaborated on the design of a building automation system that would permanently reduce kW demand and also provide automated demand response for NYISO curtailment opportunities. A recursive building automation protocol that constantly monitors current conditions and feeds that information back into itself for fine tuning with amazing results. The protocol was designed to pre-cool the building during exceptionally hot days, limit the operation of coincident air conditioning systems to 80% while safeguarding space temperatures and implementing a demand response protocol.
Project Highlights Include:
The carbon offset for this project is based upon saving 841,000 kWh annually resulting in 639 Tons of Carbon Dioxide removed from the atmosphere each year which roughly equates to the following metrics:
