Selex ES, a global technology company owned by Finmeccanica, announced that
its new digital building operating system solution, Di-BOSS™, aided local
utility load management during a July heat wave. Energy usage reductions in
two NYC buildings managed by Rudin Management helped the utility manage load
and maintain electric grid reliability for its customers.

Selex ES developed Di-BOSS in partnership with Columbia University’s School of
Engineering and Applied Science and Rudin Management, one of NYC’s largest
privately held property management companies. The next-generation system is
installed in Rudin’s buildings at 345 Park Avenue and 560 Lexington Avenue.

During the week of July 15, Con Edison and the NYISO asked property managers
to reduce electrical consumption to decrease demand on the energy grid. Rudin
implemented several “demand response” strategies which included disabling some
elevators, raising chiller settings, turning off non-critical equipment,
decreasing ventilation fan speeds, and asking tenants to turn off excess
lights and unnecessary equipment. These practices, when performed by many
buildings on the grid, can help shed enough load during peak consumption
periods to aid grid reliability. “We often work with the utility on reducing
demand during critical periods,” says Gene Boniberger, SVP of Operations at
Rudin Management. “Di-BOSS provides situational awareness and real-time
control allowingbuilding operators to drive and maintain load reductions
throughout the curtailment period without affecting tenant comfort.”

According to Boniberger, a typical building can reduce electrical load between
5% and 10%, depending on whether steam or electricity drives the HVAC system.
During the five-day energy curtailment period at 345 Park Avenue,which uses
steam, Rudin Management reduced load by over 10%.At 560 Lexington Avenue,
which uses electricity, they reduced load by over 30%. “The buildings together
shed over one megawatt of demand load each day of the curtailment event,” says
Boniberger. “That’s encouraging for energy sustainability.”

Commercial buildings use a substantial amount of electricity, especially in
summer and winter when HVAC systems work under taxing conditions. Rebecca
Craft, director of Energy Efficiency and Demand Management at Consolidated
Edison, says of Rudin’s success with Di-BOSS, “We are excited about Rudin’s
advances in load management.We see this type of technology as an important
tool for utilities and customers to work together and advance grid
