Monthly Forum: Urban Heat Island and COVID-19 – A Perfect Storm?
Summer in the City: Urban Heat Island, Environmental Justice and Covid 19– a Perfect Storm?
Temperatures this summer are rising to uncomfortable levels. But what policies are in place to assist people who are confined to small, crowded apartments, with inadequate ventilation and no air conditioning —or unaffordable air conditioning—in the case of a heat wave? What are the environmental justice issues that should be considered, since traditional practices like opening community centers and shelters may be contraindicated in the era of Covid? What populations are being disproportionately affected by urban heat and climate change? Please join Adriana Espinoza, Senior Advisor for Environmental Justice, NYC Mayor’s Office of Climate Policy and Programs, who will speak about environmental justice from a macro level, and how systemic inequality and environmental racism has created the disparities that exists in the City today. She will also discuss how the City plans to better incorporate equity and EJ into the city climate decision-making. To dive deeper into the conversation, Mike Harrington, Assistant Director of the Tishman Environment and Design Center, will speak about the historical inequalities of urban heat island impacts on communities and some possible solutions from a policy and design perspective. He will also share some of the lessons learned from personal experience and the recently released “Turning the Heat” report that he co-authored as part of the Urban Design Forum’s Forefront Fellowship. Sonal Jessel, Policy & Advocacy Coordinator at WE ACT for Environmental Justice, will discuss what makes extreme heat a public health issue, why there are inequities in impact, and how communities cope. She will also highlight particular challenges that exist for vulnerable populations this summer due to COVID-19.Here is the Link to register:

October Forum Recap: Passive House High Rise

High-rise Passive House buildings were the subject of GreenHomeNYC’s monthly forum in October. The three presentations provided attendees with an overview of what implementing Passive House standards looks like in real life.
Gahl Sorkin Spanier of the Association for Energy Affordability (AEA) kicked off the evening with a presentation on how best to go about building a high-rise Passive House (PH) project. Kevin Brennan, formerly of AEA and now co-owner of Brennan Brennan Insulation and Air tightness, joined Gahl in sharing learnings from Passive House projects and training. AEA recently worked on an 86-unit PH affordable residence for seniors in Queens, in partnership with the non-profit organization HANAC.
Kevin Brennan & Gahl SpanierGahl emphasized the importance of holding training for the various trades building a PH project, noting that the main sources of air leakage are often at details where trade responsibilities are unclear. It is key, therefore, that training not only instill understanding of PH requirements, but also recognition of the importance of collaboration and coordinating across trades. Another takeaway from AEA’s experience is that training should not include more theory or math than necessary. Gahl noted that any general contractor personnel in a supervisory role should not only receive training, but also be empowered to teach others.

February Forum Recap: How to be Cool and Efficient
by Yiran Song Air conditioning is increasingly considered to be a required amenity in both residential and commercial settings. But concerns about global warming and greenhouse gas emissions gives us no time to waste in achieving more energy efficient AC systems. In the February GreenHomeNYC Forum “How to be Cool and Efficient”, three industry experts provided a detailed description of the mechanics of AC systems and the industry as a whole.
Systems and Relative Energy Efficiency
Brendan Casey, of Fujitsu General America, believes that the Variable Refrigerant Volume (VRV) or so-called Variable Refrigerant Flow (VRF) system is the future of AC systems. Even though VRF can be carried as cooling only, building owners and management companies in places like New York City should consider either heat pump or heat recovery systems which provide both cooling and heating. The heat recovery system carries higher installation cost, but it can provide both heating and cooling at the same time to different zones based on demand with only one control.
