“‘‘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.’ “

Improvements You Can Make for Local Law 87: One Co-op’s Story

“In conjunction with the Multifamily Performance Program (MPP) offered by the New York State Energy Research and Development Authority (NYSERDA), the co-op would be to install a separate domestic gas-fired hot water heater. Currently, the building provides residents with hot water for things like showers and dishwashing by utilizing steam-coilers in the boiler. ‘That requires the boiler to be operating year round, even in the summer,’ says Michael Scorrano, managing director at the energy-services company EN-POWER GROUP, which performed work at 110 Riverside Drive.

There is a small existing Con Ed line that provides natural gas for in-unit stoves and the building’s dryers. Scorrano says it is possible that the line could accommodate a hot water heater… ‘It would cost about $100,000 and it has a 3.6-year ROI [return on investment],’ Scorrano says. An upgraded system would mean the building would use 17 percent less energy annually, easily allowing the co-op to meet its MPP goal.

… [Co-op board member] Valentine says his co-op board sees Local Law 87 not as another burden imposed on them by New York City but rather as an impetus to do the types of things that will save money in the long run.”
