GreenHomeNYC’s Pandemic Pivot Proves the Power of Commitment and Community

By Melanie Mason   We have spent the better part of our year in throes of the COVID-19 pandemic—social distancing, Zooming, washing our hands like crazy, and carrying out GreenHomeNYC’s mission from the kitchen table. This has almost begun to feel like a normal part of our routines. But at the beginning of the lockdowns back in March, the challenges to life as usual suddenly felt very far from “normal.” Just like everyone else, GreenHomeNYC had to quickly adapt to this new way of being. A testimony to our incredibly driven volunteers, together we dove headfirst into tackling how GreenHomeNYC would go from a live and lively in-person community to operating fully remotely.   Said GreenHomeNYC’s board president Lucie Dupas, “The board is so thankful for all the amazing work that our volunteers are able to get done safely from their homes—this year has been incredibly challenging in all aspects of life, and we are amazed on a daily basis by how passionate and resilient our whole community is!” (more…)

Recap: Tour of the East River Compost Yard

  By Jonathan Oriondo   On August 15th, GreenHomeNYC hosted a tour of the East River Compost Yard in Manhattan, where participants learned what it takes to compost on a community-wide scale. Lia Lucero, the outreach coordinator for NYC Compost Project, personally guided us throughout the site.    At first glance it was not obvious that this facility’s main goal was community education. Right on the river, in the middle of a park, this place was huge! There were piles of compost at various stages of the digestion process. Most of the facility was outdoors with a small administrative building towards the road, and it was all surrounded by a formidable fence. It was very impressive—even the smell.  (more…)

GreenHomeNYC Year in Review: Taking on the Environmental Challenge

by Pamela Berns

It’s been a year marked by extreme weather events, with hurricanes, fires, droughts, and flooding all across the globe. In the United States we saw Houston drown and Santa Rosa burn just a few months after Trump’s pullout from the Paris agreement in June. Climate advocacy groups, local policy makers, corporations, entrepreneurs, individuals, and nonprofits all stepped up their game in defense of the planet, and GreenHomeNYC was no exception.   Thanks to the dedication of our volunteers, we were able to deepen our commitment to providing education and calls to action. Our speakers and our blog writers shared critical information on local policy, business actions, and academic initiatives. Record numbers of event attendees turned up to hear from innovators in energy, food waste, recycling, and sustainable building. Green careerists came out to find out where to point their compasses in the new paradigm.   We’re proud of the hard work that went into this challenging year, and hope that our contributions made a difference. Here are just a few GreenHomeNYC highlights for 2017:   (more…)

November Green Building Tour Recap: Building Towards Resilience

by Brigitta Berze  

It’s been five years since Hurricane Sandy hit the East Coast, leaving a trail of destruction in the New York area.  During the “Building Towards Resilience” Green Building Tours event, Henry Gifford of Chris Benedict R.A., led a tour through 327 and 334 East 8th Street – two Lower East Side buildings that were affected by the hurricane – providing a firsthand look at renovations that were made in the aftermath of the natural disaster.


The tour began in the noisy basement of 334 East 8th Street, with a description of the damage after Hurricane Sandy, including the conditions that the workers had to endure. The elevator in this building is not counteracted by weights to lift the elevator car, but instead uses oil mixed with other chemicals in a hydraulic elevator machine.  As the water rose to about six feet above the basement floor, the oil and chemicals mixed with the flood waters, creating a hazardous condition for workers.  The slippery mix of oil, water and sewage caused the superintendant to get a foot infection that landed him in the hospital for three days.

Javits Center: The Largest Green Roof in NYC

by Shari Baitcher   In New York, a city with one of the highest population densities in the U.S., every square foot is valuable. In recent years more thought has been given to the space on top of buildings. With 840,000 square feet of exhibition space occupying 6 city blocks, the Jacob K. Javits Convention Center has recently introduced the second largest green roof in the United States.   Rick Brown, Chief Engineer for the Javits Center, exuded passion for the recently implemented sustainability project as he took GreenHomeNYC volunteers and community members behind the scenes of the convention center. We stopped at the IT office where he explained how they capture the heat generated by the computers and servers to help offset the building’s heating demand. Sensors have been installed all over the building to monitor efficiency, revealing a 26% reduction in energy consumption since the renovations have been completed. Additionally, water consumption has been reduced by 2.9 million gallons.  Efficiency measures such as these contribute towards the Javits Center’s goal of earning LEED Silver certification. (more…)

August Tour Recap: R-951, A certified Net Zero in Brooklyn

By Brigitta Berze DSC_3797 (681x1024) There was much excitement buzzing in Prospect Park, Brooklyn on the eve of August 5th, 2015 as Brooklyn’s Deputy Borough President, Diana Reyna, presented citations to the teams involved in the completion of the first certified net zero capable passive house in NYC.  Paul Castrucci , the architect for this building, along with developer Further, Inc., and Aeon Solar were honored for their achievement. DSC_3852 (1024x681)   R-951 Residence is made up of three duplex 1,500 square feet condominiums that which have unique outdoor spaces and beautiful interior design, as well as, sustainable function. The building does not require fossil fuel, and natural gas to heat, cool, or light the space. The living units have their own supply of 4kW Solar Photovoltaic systems on the rooftop that acts as shading for the roof accessible areas. This feature makes it possible for the on-site panels to generate enough energy to power each unit ‘over the course of a year’, as promoted per design. The high performance building envelope is the most important feature of this and any passive house. The walls are insulated to R-40, the windows and doors are ‘tilt and turn’ R-9 triple glazed. The envelope is sealed to 0.6 air changes per hour at 50 pascals pressure, which also creates a soundproof effect for a quiet indoor environment. Passive design includes large south-facing windows to maximize winter solar heat gain, and the metal accordion style screens provide shade during the summer season.

  Some of the most impressive features of the house are the mechanical systems, where the magic truly happens. Ventilation is provided by an energy recovery ventilator (ERV) that recovers 94% of energy from air exiting the building. The Zehnder ERV filters indoor air for pollen and particulates, providing fresh air while minimize energy loss and reducing the need for heating and cooling equipment. Each unit is heated and cooled by electric heat pumps with a SEER rating of 16.5.  Electric heat pumps are also used for domestic hot water production and also can cool indoor air. The ground unit has a spacious, green backyard, which has a 1,200 gallon irrigation rainwater harvesting system.   We would like to thank Paul Castrucci, Further, Inc. and Aeon Solar for allowing us to see R-951 Residence firsthand, and thank you to everyone who came out to support the progress of green buildings in NYC.
