On Tuesday I trekked over to the Javits Center on the West Side to spend the day at the Green Buildings NY expo. Overall it was an interesting collection of professionals and products that focused on managing and fitting buildings for sustainability. I had the chance to talk to a number of people and sit in on some conference sessions. Here are some of the highlights that the expo had to offer:
Efficiency through Water Reuse
I find it fascinating how seasoned professionals of any industry can create a presentation to highlight all of its environmental short comings. Edward Clerico of Alliance Environmental LLC painted a bleak picture of our water infrastructure. In his efforts to promote on-site filtration and reuse, he began in saying that our system of water supply and disposal uses 8 quads (that’s quadrillion BTUs) of energy every year. At the same time he pointed to how far on-site filtration systems have become and how greywater could become increasingly common. Uses such as site irrigation, cooling tower make-up and laundry washing can help buildings like the Solaire and One Bryant Park cut their water usage and discharge in half.
Green Demolitions
Based out of New England, Green Demolitions offers free demolition and removal of kitchens and bathrooms so that they can be completely reclaimed and resold for use in new projects. The prospective client can enjoy a sizable tax deduction instead of a hefty contractor bill for the removal. Speaking with John Green, manager of their Bethel, NY store, I learned the company donates all of its projects to Recovery Unlimited—a non profit dedicated to helping with substance abuse. Consumers can regularly spend 50%-80% less for a new kitchens, bathrooms or appliances. Their cause has lead them to not only provide a charitable source of income, but divert tons of material from landfills as they promote reuse.
Greenpatch Pavement
Greenpatch is one of the players exploring the new realm of cold asphalt pavement. Hearing “green” and “asphalt” next to each other was surprising to me, but the product specializing in filling potholes and repairing roads has numerous sustainable benefits. Not only does the asphalt require no heat to be applied (which saves a generous amount of energy) but it can also be manufactured at lower temperatures (which saves even more.) Its mix contains 40% recycled asphalt and no petroleum solvents. Unlike other cold-patch products, Greenpatch contains zero Volatile Organic Compounds (VOCs) that normally can leech into the ground or off-gas into the air. Even their packaging is recyclable. Overall, it was an impressive product.
JM Insulation
Johns Manville is a producer of many building products, one of them being fiberglass insulation. Again, normally the term causes environmentalists or green building proponents to roll their eyes and turn back towards soy-based, blow-in alternatives. But these guys are making an attempt to give fiberglass a better name. Their insulation uses 25% recycled glass with 20% being post-consumer glass (more than any other manufacturer.) They actually claim that fiberglass insulation is the largest secondary market for recycled glass. Their new line has removed all formaldehyde, a common ingredient in bonding agents, from their insulation to help with indoor air quality.
Retro-Commissioning
Allan Skodowski gave an enlightening talk on the importance of retro-commissioning. Any building seeking LEED certification is familiar with commissioning, a process that tests the designed systems of a building to make sure they function as intended and with peak efficiency. But Skodowski, who helps commission buildings for Transwestern, says that existing buildings should also be commissioned to ensure their systems are not falling into lethargy and negligence. As technologies improve and systems wear down, most buildings can run at around 78% of average energy costs through commissioning—a number that can drop to 60% with dedicated, consistent study.
