How Far Can You Go on the Green Scale? Shades of Green

 Talk of “green” homes and buildings these days often evokes images of roof gardens, solar  panels, and even wind turbines humming in the background. For most co-ops and  condos however, “going green” comes incrementally, in much smaller measures.  

 Starting with simple things like turning off lights or phasing out incandescent  bulbs, and moving to major undertakings such as investing in solar energy,  individual owners and boards can take any number of steps on the road to a more  environmentally conscious lifestyle—and pocket significant savings along the way.  

 Pre-war buildings, townhouses, and even brand-new condos all present  opportunities for green improvements that can lead to increased comfort and  continuing cost savings—it’s just a matter of finding the shade of green that best fits your building’s means and motivation.  

 Taking the First Steps

 Reining in electric bills—and saving energy—in your building can start with installing compact fluorescent bulbs. According  to the Union of Concerned Scientists, if every household in the United States  replaced just one regular incandescent light bulb with a compact fluorescent  light (CFL) bulb, it would prevent 90 billion pounds of greenhouse gas  emissions from power plants. That’s the equivalent of taking 7.5 million cars off the road, and over the life of  the bulb, saves $30 in electricity costs. Count up all the bulbs in your  building, and all those $30 add up quickly.  

 The U.S. Environmental Protection Agency (EPA) suggests starting by placing the  CFL bulbs in fixtures that are used frequently and left on for long periods of  time, so beyond individual units, boards and managers may consider them a good  choice for common areas like hallways, and community rooms.  

 An added advantage of CFL bulbs is their long life span. While they cost more to  purchase, they generally last for eight to 12 times as long as a standard bulb—which is good news for supers and maintenance personnel who won’t have to climb ladders several times a year to replace burned-out  incandescents.  

 Other simple, greener options can be implemented with the help of building  residents. While reviewing ideas to help shareholders and unit owners cut  electric use, Deborah Meehan, a Certified Energy Auditor and owner of New  England Energy Audit in Londonderry, New Hampshire suggests taking a good look  at home appliances.  

 Consider the refrigerator, just to name one major example. “Refrigerators built before 1995 can consume an considerable amount of  electricity, even if they’re working fine,” Meehan says. “The only way you can tell is by testing with a meter.” In one home she visited, she says, the refrigerator alone was costing the  homeowner $350 a year; when they replaced it, the cost dropped to $8 or $9 a  month.  

 The New York State Energy Research and Development Authority (NYSERDA) echoes  Meehan’s advice, advising apartment owners to “avoid purchasing used refrigerators, as an older refrigerator often uses more  than three times the energy of today’s models. [Also,] select a refrigerator/freezer with energy-saving features—it will use 20 percent less electricity than the standard model, saving you  approximately $60 a year.” To that, NYSERDA also recommends the following easy fridge tips:  

 • Defrost your refrigerator regularly so it can operate more efficiently, and do  so only on weekends to avoid peak load.  

 • Vacuum and clean the condenser coils, motor and evaporator pan of your  refrigerator once or twice a year, and leave space between your refrigerator  and the surrounding walls and cabinets to allow air to circulate around the  coils.  

 • Keep your refrigerator away from the stove and heat registers. By being next to  those items, you’re making your refrigerator work twice as hard and decreasing its overall  efficiency.  

 • Test your refrigerator and freezer by placing a thermometer inside for an hour.  Refrigerators should average between 36 and 38 degrees, and freezers should be  between 10 and 15 degrees below zero.  

 • Make sure the seals on your refrigerator, freezer and oven doors fit tightly.  

 • Another often-overlooked opportunity for easy greening may be found in the  basement, where dehumidifiers often run year-round whether they’re needed or not. “They really only need to be on in the summer,” says Meehan, “and they should be the kind that turn off when you reach the desired level” of moisture in the air.  

 Changes to laundry rooms can improve water and energy use as well. Nearly 10  years ago, the U.S. Department of Energy conducted a washing-machine study at a  condominium complex in Boston to determine the potential savings of converting  traditional “vertical-axis” machines (top loaders) to “horizontal axis” machines (front-loaders). Their finding: “The changeover to the h-axis washer reduced the average water consumption by 41  percent. The washer energy consumption including washer energy and hot water  energy fell by 50 percent due to the hot water savings as well as more  efficient motor and controls. The dryer energy savings for the study was 22  percent, which mainly attributed to the high speed spin cycle of the h-axis  washer reducing the remaining moisture content of the clothing after wash.”  

 Clean Can Be Green

 Greening your building doesn’t just begin and end with changing light bulbs and performing energy audits—changes to the cleaning and maintenance products used by your building staff can  help reduce environmental impact and improve its green profile.  

 The first step in switching to green products in your building is to identify  your options—it may be as simple as discussing alternative lines carried by the cleaning  supply distributors you work with already, or it may involve a little more  legwork and research.  

 Franklin Cruz, president and CEO of Direct Environmental Corporation, a company  specializing in green cleaning products and services with offices in the Bronx  and Newark, New Jersey, says that building owners and managers “should educate themselves on the subject so that they can separate fact from  fiction. Naturally, they are going to get some resistance from their existing  cleaning supply company because they don’t want to lose the business. So, I think the board needs to do the necessary  research.”  

 The second—and perhaps most vital—component of any change is to get your building staff on board beforehand. After  all, they’re the ones who will be using the stuff, and if a switch to  environmentally-preferable products will require more effort to achieve the  same result as what they’re currently using, their enthusiasm will likely be tepid at best. Attitudes  like ‘If it doesn’t smell like bleach it won’t clean,’ and ‘If it says environmental on the label, it must be weak,’ are common—especially among staffers accustomed to using harsh chemicals and  industrial-strength cleaning products.  

 It may take a short period of trial-and-error before you find the right green  products for your building’s needs, but enlisting staff members to test new products before they’re ordered in bulk is a good start. It allows staff to be part of the decision,  weeds out products that might not be as effective, and can improve your  building’s green profile by phasing out environmentally detrimental products.  

 Finding the Right Shade

 Going further down the green path requires more effort—and more capital outlay, at least at the beginning, say the experts. Overhauling  your insulation building-wide, implementing co-generation programs, installing  hydroelectric or solar elements, or even incorporating wind power are major  steps that not every building is in a position to take either financially,  structurally, or both. Determining whether or not such programs are a  possibility for your particular building community requires a great deal of  research, and collaboration with qualified professionals.  

 Meehan agrees. “One of the biggest problems I see in condos is the lack of insulation,” she says. “When you lay fiberglass between floor joists, it leaves gaps, and often the  builder throws it in badly… and that’s where most of the heat loss is.” In multifamily buildings, individual unit owners may not be responsible for the  insulation in their own units, so it’s a good idea, Meehan says, to check with your board before digging around in  your floors or walls and altering the insulation.  

 What has proven to be helpful, she adds, is for owners and shareholders to work  with their boards and have a full energy audit conducted on the building to  determine where energy is being wasted, and what steps make the most sense in  trying to alleviate the waste. A thorough audit might include thermal imaging—which shows where heat is being wasted—and a “blower-door” test to hunt down air leaks in units or the building itself.  

 Of course, your audit—or your new cleaning protocols, or your shiny new solar panel array—is only helpful if it’s implemented or installed properly, and your own people are on board with it  from the start. “With any scientifically advanced technology, implementation is as crucial as the  technology itself,” says Gerald Hirsch of The Water Group, LLC, in Brooklyn. “There are a number of factors that can impede performance and results. So make  sure that you are dealing with a reputable company that has engineers  [experienced] in implementing these technologies. The savings difference  between getting it working at 100 percent versus 75 percent will more than  cover any extra cost.”  

 Full energy audits, which generally cost between $300 and $500, come with  reports detailing improvements that recommended—and which are actually doable—what they cost, and what the payback period is likely to be. And like a growing  tree, seeing a return on your green investment may take some time, says Meehan.  Payback times on greening efforts can vary greatly.  

 “If it’s between one and seven years, that’s a no-brainer,” Meehan says. “At seven to 10, you might want to think about it. And over 10, it’s generally not recommended.” Warm and fuzzy feelings aside, she says, “You have to look at it the same way you look at investing in anything else—you look at what your return is before you make the decision.”  

 It’s true that more and more new construction projects are using green materials  and technologies, but older co-ops and condos shouldn’t feel left out of the movement toward sustainability and reduced environmental  impact. Things like encouraging residents to turn off lights in empty rooms, or  enforcing recycling rules may be obvious, but experts who inspect buildings—even recently-constructed condos—often find that they haven’t been taken, even as energy costs rise and discussions of climate change  dominate the media. Whether your building is a pre-war landmark or a  spanking-new glass-walled high-rise, at least some shade of green is within  reach of unit owners and buildings alike.
