Harvesting Negawatts: Getting Historic Buildings to Near-Zero Energy

How can historic urban buildings be upgraded to contribute to an energy-efficient, decarbonized built environment? This session explores challenges and opportunities associated with historic buildings in dense urban environments through the lens of three LEED Platinum renovations, including two projects within designated Historic Districts and one that pursued historic preservation tax credits. In each case, significant improvements were made to the building envelope, mechanical systems, and indoor air quality, while still meeting required historic standards and guidelines. The case studies present a building typology--three to four story brick masonry buildings--that is widely prevalent in US cities and represents a huge opportunity for energy reductions if effective strategies can be deployed. In addition, retrofitting these buildings is an important strategy for minimizing the embodied carbon of new construction, and therefore the total carbon impact of the built environment. Drawing on Sol’s decades of experience working at the intersection of historic preservation and sustainability, this presentation shows how historic building retrofits can be a key part of the solution to climate change.

Jacqueline brings over a decade of experience in the sustainability industry, starting early in her career as an ENERGY STAR HERS Rater and most recently working for the State of Ohio as an Energy Conservation and Sustainability Administrator. As the Sustainability Administrator, Jacqueline managed all sustainability initiatives for a building portfolio of over 12.3 million square feet. She was also instrumental in achieving the first LEED correctional facility in Ohio. As Director of Certifications at Sol, she manages projects in multiple sustainability certification programs, including LEED, Enterprise Green Communities, and WELL.
