No Sweat: Paying for an AC Overhaul

Posted on | by tauseef | Leave a Comment on No Sweat: Paying for an AC Overhaul

“[Newport East’s] 25-year-old central cooling system was showings its age and, despite repeated repairs, kept breaking down… [Board member Andrew] Weiss hired Michael Scorrano, managing director of the engineering firm En-Power Group, to study all possible energy-efficiency upgrades, including rebates and incentives.‘[Scorrano says] First, we identified how they could become more energy-efficient and also how to get rebates from New York State Energy Research & Development Authority (NYSERDA) and Con Edison. Then we switched to natural gas, did lighting upgrades, and started planning a new cooling and heating system.’

… The $1.4 million paid for the all-important chillers for the central cooling system. In addition to cooling the building, the chillers produce waste heat, which fuels the hot-water boilers. This means that during the summer months, the hot water is heated solely by the chillers. ‘This means we have lower operating costs, leave a smaller footprint, and have lower maintenance,’ Weiss says. According to engineer Scorrano, the co-op also saves more than $175,000 per year.

The project was finished on budget, thanks in part to a $250,000 rebate from NYSERDA that will help replenish the reserve fund.”

Retrofitting Residential Buildings

Posted on | by tauseef | Leave a Comment on Retrofitting Residential Buildings

“Energy audits of multifamily buildings, now mandated in New York City for structures over 50,000-sq.-ft., typically identify a common set of cost-effective retrofits and operational modifications to reduce energy consumption. “This not about green roofs and solar panels,” Padian says. ‘It is about taking an existing building and making it work right.’ …The 20-story, 151-unit co-op at 180 East End Avenue, New York, is replacing antiquated steam boiler controls with Heat Timers with outdoor temperature resets. The old controls were causing boiler short cycling, which increased fuel consumption, says Michael Scorrano, managing director at the En-Power Group, Katonah, N.Y.

Alternatively, apartments can be outfitted with temperature sensors that communicate with the boiler. The controls adjust the hydronic loops better by either running the system longer or turning off pumps when the system has satisfied internal temperatures, Scorrano explains.”

Retro-Commissioning: Using Local Law 87 to Push Money-Saving HVAC Tweaks

Posted on | by tauseef | Leave a Comment on Retro-Commissioning: Using Local Law 87 to Push Money-Saving HVAC Tweaks

“‘‘They used Local Law 87 as a catalyst to really move forward,’ says Michael Scorrano, managing director at the energy-services company EN-POWER GROUP, which performed work at 110 Riverside Drive.

… Also as part of the retro-commissioning angle, EN-POWER will perform a programming change on the boiler to reduce the overnight temperature by one degree. That work will cost only about $1,000, but just that one degree will save the building $2,500 annually.

‘Retro-commissioning is not supposed to be a major item,’ [Scorrano] says. ‘It’s about tweaking things and making sure that they work the way they should.’ “

Deep Energy Retrofits in Multifamily Residences: ENPG Forum hosted by Building Energy Exchange (BEEx) on Tuesday, May 8th

Posted on | by tauseef | Leave a Comment on Deep Energy Retrofits in Multifamily Residences: ENPG Forum hosted by Building Energy Exchange (BEEx) on Tuesday, May 8th

A deep energy retrofit may seem daunting due to its required capital investment and time. Yet, a holistic, integrated retrofit plan is the key to better building performance and major energy savings. Buildings can also use the retrofit as an opportunity to improve resiliency to extreme weather events by adopting on-site energy generation systems like combined heat and power (CHP) and solar photovoltaic panels.

Organized by Building Energy Exchange (BEEx), this forum on Tuesday, May 8th at 9 AM will showcase the deep energy retrofits at the Fairview, a large multifamily residence in Forest Hills that underwent a natural gas conversion, chiller upgrade, and solar PV panel and CHP system installations. The panel consists of representatives from EN-POWER GROUP, NYSERDA, Tecogen, and the Fairview Owners Corp. Together, the speakers will share their project implementation experiences and discuss the challenges, new system performance benefits, and rebates and incentive programs utilized to help fund the retrofit.

Smart Electric Meters Are Coming

Posted on | by tauseef | Leave a Comment on Smart Electric Meters Are Coming

“What you need to know. Your building’s electric meter is going to get smart.

… ‘Oftentimes the peak demand of a co-op or multi-family building is in the evening hours,’ says Thomas Morrisson, Director of Energy Management at EN-POWER Group, an energy consulting firm, ‘versus commercial buildings [with] peak demand around noon to 3:00 o’clock.’ For many multi-family buildings, switching to a time-of-day rate, based on your smart meter readings, could lower your electricity bill.

Be smart. What’s using the most electricity? There are a lot of building systems to examine, and while the smart meter is a start, it won’t provide the answers you need. Working with an energy consultant is a good next step. A consultant can advise if metering specific building systems and installing variable frequency drives will reduce your load, and if this is a cost-efficient move. Plus, Con Edison wants you to reduce demand. They offer energy efficiency and demand response programs to incentivize you, and smart meters (or an interval meter) are necessary to participate.

The bottom line. Smart meters are a great way to start to figure out how to save on electricity costs. Con Edison is tackling installation borough by borough and county by county. Staten Island is done, Westchester is almost finished, and they are beginning to roll out Brooklyn and Manhattan. Queens and the Bronx will follow.”
