GREEN IDEAS

Local Law 84 of 2009 mandates that New York City buildings larger than 50,000 square feet must record and track their energy and water use, with the grades made public. This allow you to see how well your building is doing and how it compares with other buildings. But energy experts say there are still kinks to be worked out: The data is not always accurate and it's difficult to access.

To paraphrase J.D. Salinger, raise high the green roof, carpenters: New York State has just expanded and extended the duration of the property-tax abatement for buildings that install an environmentally friendly "green roof" — one with plant life that helps provide energy-saving insulation and other eco-benefits. Amending the original 2008 law, it doubles the previous maximum benefit of $100,000, adds new plant species to the list of those applicable for the tax break and allows new drainage and other structural provisions to make installation easier.

Baby, it's cold outside, and your boiler and heating system are going full-blast. That's a big energy cost for your cooperative or condominium. Fortunately, you have options. With supplies of natural gas high and prices low (though higher than last year), it may make sense to switch from oil to gas — or perhaps to to a dual-fuel burner capable of operating with either. In our latest Teachable Moments column, two veteran property managers relate some real-world experiences of how they helped their co-ops and condos pull the trigger on pulling the switch. Did it work? Well, one place is saving $50,000 a year and others are saving six figures. Might be worth the energy to consider.

Under Local Law 84 of 2009, large buildings must record and keep track of their energy and water use — and then the city posts the results for all to see. The letter grades are linked to a numerical score called the Energy Use Intensity (EUI), which measures the energy used by a building per square foot, per year. The median EUI for multifamily buildings in New York City is 132.1. Score a 109 or lower and you earn an A; higher than 160 is a D. But in practical terms, how well do these grades translate to real-life energy use?

The concept has been used in New York City since the 1980s, but shared savings agreements have only recently begun gaining traction with co-op boards and condominium associations as a way to finance green projects. It involves finance companies, energy consultants or contractor / vendors financing your green project with the promise they'll be repaid annually, with interest, through the subsequent energy savings. So when and why would such an arrangement be appropriate for your own building?

You want to do a lighting retrofit in your garage or convert your boiler from oil to gas. Where do you get the money? If your building is the right size, you may want to try a shared-savings agreement.

"For us, it was a no-brainer," says Herbert Freedman, the managing agent of Riverbay Corporation, which runs the 15,000-unit Co-op City complex in The Bronx.

Harold "Heshey" Jacob, longtime property manger of the sister co-ops Hillman Houses and East River Housing, knew in 2009 that sludgy and sooty No. 6 heating oil was on its way out. With the help of New York State Assembly Speaker Sheldon Silver, who lives in Hillman, he convinced the co-op boards of the 2,500 -unit, seven-building complex to switch to dual-fuel systems using cleaner No. 2 oil and, mainly, natural gas. It was a big, big switch. How did he manage to convince not one but three boards to go that route?

For a recent hallway renovation at an Upper East Side co-op, the plan was to remove old wallpaper and replace worn carpeting. But in the process, remembers Marion Preston, former board treasurer of the 111-unit co-op, the previous board had ordered a huge supply of excess wallpaper and carpet. "They had extra of everything just in case, but no one ever used it or needed it," Preston says. "For our job, we had all-new material, so we obviously didn't need this anymore. I couldn't bear to just toss it out. It was still in its original packaging." So what to do?

Harold Jacob is the longtime property manger of the Hillman Houses and East River Housing, two of the four communities comprising the Lower East Side's Cooperative Village — colloquially called Co-op Village or "the Grand Street co-ops." He decided in 2009 that the time had come for Co-op Village to wean itself off the highly polluting No. 6 heating oil, ushering in a new era of energy efficiency, dramatically reducing pollution and lowering the energy consumption of the 2,500 apartments in the seven buildings he manages. Hillman and East River now each use a dual-fuel system that relies mainly on natural gas and can periodically switch to the cleaner No. 2 oil.

The co-op at 201 East 66th Street in Manhattan heats both its apartments and its domestic hot water with steam purchased from Con Edison. Steam heat is expensive, since it's generated at a Con Edison plant and then piped into the building through city pipes. Not only is the 52-year-old building saddled with an expensive and inefficient system, its equipment is aging and its chiller for air conditioning needs to be replaced. Could co-generation be the answer? And if so, how do you sell it to your board and residents?
