Red reflector paint11/20/2023 “Every roof has the potential to help solve the climate crisis,” said Gwen Schantz, Brooklyn Grange’s co-founder and chief creative officer. It is atop a property owned by Steiner NYC and was installed by Brooklyn Grange, an organization that designs and maintains green roofs, featuring vegetation, and rooftop farms. A new 11,500-square-foot “green roof” at 399 Sands Street in the Brooklyn Navy Yard features a mix of sedum and wildflowers, and its effect is augmented by a white cool-roof system by Siplast, a commercial manufacturer. “Rooftops present an important opportunity to both mitigate and adapt to climate change, and to address a range of environmental and social issues,” said Emily Nobel Maxwell, the cities director for the Nature Conservancy in New York.Ĭombining different roofing types with reflective coatings and solar panels can boost energy benefits. “We have projects all across the city, so I can see the impact that we are making in NYC.” “We are making an impact on the environment and on people’s individual lives,” said Zakiyah Sayyed, 36, who resides in the South Bronx and is a crew supervisor for the Hope Program. The remainder of the roof is expected to be coated in 2022 or later, depending on the availability of funds. The coated roof is expected to help cut down on the energy use for air-conditioning, reducing the amount of greenhouse gases expelled into the atmosphere. The Hunts Point Produce Market, the country’s largest wholesale produce market and a longtime mainstay in the borough, took a step toward climate action in October, coating about 30,000 square feet of its dark 800,000-square-foot roof with a material known as Elasto-Kool 1000, a white paint infused with silicone to reflect solar heat and UV rays and decrease indoor and surface temperatures during summer months. Installing cool roofs, which involves lightening the surface color of rooftops to reflect and not absorb heat, can temper excessive heat from the top down and reduce the urban heat island effect - a common and adverse consequence of climate change where air temperatures are significantly higher in a city than in surrounding areas, even at night. HR coatings are used in common laser optics applications such as folding a. Absorption and scatter during reflection lead to decreased throughput and potential laser-induced damage. Highly reflective (HR) coatings are used to minimize loss while reflecting lasers and other light sources. ![]() This sweltering effect can be attributed to the built environment, with its lack of protective tree shade and swarms of traffic and surroundings cramped with glass, asphalt, metal and concrete. This is Section 11.4 of the Laser Optics Resource Guide. In some neighborhoods, like the Hunts Point section of the South Bronx, which ranks as one of the city’s most vulnerable areas to heat, extreme temperatures actually linger, contributing to increases in heat-related illness and deaths. Last summer, New York City endured three heat waves and many days when the temperature climbed above 90 degrees.
