Episode 13: Unearthing Geothermal Energy

In this episode of Building Tomorrow, Mark MacCracken, the Vice President of CALMAC at Trane Technologies, joins host Ellen Honigstock and co-host Whitney Smith to discuss thermal energy storage. Thermal energy storage is a clean energy alternative that involves using ice for cooling and water for storing heat. Listen in to learn more about how this method of heating and cooling compares to fossil fuel systems and conventional electric resistance. HOSTS: Ellen Honigstock, Senior Director, Education, Urban Green Council Whitney Smith, Senior Climate & Sustainability Leader and Associate Principal, Arup GUEST: Mark MacCracken, Vice President and CALMAC Portfolio Leader, Trane Technologies

To decarbonize New York City buildings, heating systems reliant on fossil fuels must be replaced with sustainable alternatives. In this episode of Building Tomorrow, Brightcore’s Jonathan Hernandez joins Urban Green’s Ellen Honigstock to discuss geothermal energy and how it can be expanded in NYC to decarbonize buildings and make them more resilient.  Listen in as they dive into the geothermal industry, and how new policies and technologies are making the installation of more ground source heat pump systems possible. HOST: Ellen Honigstock, Senior Director, Education, Urban Green Council GUEST: Jonathan Hernandez, Director of Business Development, Geothermal, Brightcore RESOURCES: Find the images and graphics discussed in the episode here.

Building systems are designed and installed separately, but at the end of the day, they have to work together in order for a building to work as intended. Commissioning makes that happen. In this episode of Building Tomorrow, Kelly Westby from Steven Winter Associates joins Urban Green’s Ellen Honigstock to discuss all things commissioning, including: Commissioning as a systems-thinking process The importance of communication Where human science and building science come together By the end of their conversation, you’ll be able to see how commissioning makes a building complete! This is a crossover episode! Make sure to listen to the Buildings + Beyond podcast to hear Kelly interview Ellen about addressing the skills gap in the sustainable building industry.

Retrofitting existing buildings can help increase energy efficiency and cut carbon emissions. But what do these retrofits look like in a place like Manhattan, where almost one-third of total floor area has landmark status and is, therefore, energy-code exempt? In this episode, Dr. Erica Avrami, Nate Rogers and Kate Reggev discuss these energy code waivers and how, despite the waivers, new greenhouse gas legislation could necessitate energy retrofits in historic buildings. This new era of regulation marks a momentous shift in regulation practices and signals a need for significant reforms to preservation policies in light of climate change. This interview expands on Dr. Avrami’s previous research, including her paper, “Energy and Historic Buildings: Toward Evidence-Based Policy Reform,” which examines the implications of a changing legislative landscape on historic preservation in NYC.

The first compliance period for Local Law 97 is here, and energy upgrades in NYC’s existing buildings will need to pick up. But what kind of upgrades are needed, and who will do the work?  Manny Pastreich, President of 32BJ SEIU, joins Urban Green CEO John Mandyck on Building Tomorrow for a discussion on how we can mobilize the green workforce to complete these energy upgrades.

Installing an energy upgrade in an occupied building is difficult. These projects are also critical to realizing decarbonization goals. In this episode of Building Tomorrow, hear from Trevor Smith, a construction manager with extensive experience in completing design-build energy projects in occupied buildings. Trevor shares tips on how to carry out these projects successfully, including how to improve communication and work better with operations staff.

Measuring and disclosing “financed carbon emissions”—or Scope 3 emissions—by banks and financial institutions is critical for investors who seek to understand climate risk in their portfolios. New York City Comptroller Brad Lander is responsible for the management of over $240 billion in pension funds and is leveraging this role to drive carbon disclosure, including Scope 3 emissions, from the companies in which pension funds are invested. On September 13, 2023, Comptroller Lander joined Urban Green Council CEO John Mandyck for a conversation about his net zero plan and how finance can be a lever for decarbonization.

In Dr. Melissa Checker’s 2020 book, The Sustainability Myth, she took a critical look at the hidden costs—and contradictions—of New York City’s ambitious sustainability agenda. Her insights into the dynamics of environmental gentrification shed light on some of the hidden forces driving redevelopment in the city.  Three years after the book was published, Dr. Checker joined Building Tomorrow to chat about what has changed in the years since and how we can equitably distribute the benefits of the green transition.  HOSTS: Ellen Honigstock, Senior Director, Education, Urban Green Council Amy Marpman, Director, Sustainability, SBM Management Services SPEAKER: Dr. Melissa Checker, Hagedorn Professor of Urban Studies at Queens College and Professor of Anthropology at the CUNY Graduate Center RESOURCES:  Link to purchase: The Sustainability Myth

Embodied carbon—the emissions resulting from the manufacturing, transportation, installation, maintenance, and disposal of building materials—will play a key role in decarbonizing the built environment.  In this episode of Building Tomorrow, Ellen Honigstock and Prateek Srivastava sit down with Stantec’s Robby Vogel to get a Structural Engineer’s perspective on strategies to reduce embodied carbon and how they can be employed in the built environment. They discuss everything from new technologies to navigating client relationships to how emerging and established professionals can learn from one another to shape the future of sustainable projects. If you’ve ever wondered what embodied carbon is and why it matters, this episode is a must-listen!

As New York City transitions away from fossil fuels, it’s imperative that environmental justice be centered in policy making, and that people from historically disadvantaged communities actively benefit from the transition. In this episode of Building Tomorrow, Zakiyah Sayyed and Anushka Maqbool sit down with Sonal Jessel, Director of Policy at WE ACT for Environmental Justice, to talk about Sonal’s career journey, WE ACT’s work with electrification and workforce training, and the importance of centering environmental justice in the electrification conversation.
