This session features an in-depth review of an award-winning multi-family low energy (Passive House) building in New York City.  We will review the technical aspects of the building, from the components to the layout and finishes with the architect, discuss motivating factors and financial decisions with the developer, and explore the challenges, solutions and best in class techniques for executing a successful project.

Multifamily buildings with good insulation, great windows, and decent ventilation systems – what's not to like? Unfortunately, over the past five years, we have received calls from multifamily building owners who are battling persistent summertime humidity problems. Comfort complaints, sweating ductwork, waterlogged drywall, and mold on furnishings, clothing, registers . . . you name it. We will discuss how we went about these investigations and the tools we used to diagnose these issues.

Transparency is the foundation for making informed decisions about the products we specify. The AEC industry is familiar with sustainability goals related to energy efficiency, but holistic discussions related to material goals across the entire team are still rare. Large strides have been made in interior product disclosure, but much less so for building envelope, MEP  and lighting systems. Without transparency our ability to quantitatively convey the magnitude of decisions made across the project team, and track progress as the design progresses, is limited.

The climate benefits of using timber are becoming better understood by owners committed to sustainability goals, but the procurement and implementation process still present challenges. Hear from practitioners from three newly constructed Mass Timber projects: the Dept. of Unemployment Assistance building in Brockton, MA; a 7-story Passive House multifamily building at 11 E. Lenox, Boston; and the Bristol County Agricultural High School.

The virtual power plant - aggregated, behind-the-meter solar, energy storage, and building loads dispatched in concert to meet grid needs - is a new model that has been pioneered in New England and is now being adopted by forward-looking utilities and policymakers across the country. This session will explain why the virtual power plant is the future of energy storage, how states can create virtual power plants using existing programs and budgets, and why this is an important new paradigm that will benefit customers and communities.

This session will share insights from three research projects focused on greenhouse gas impacts of efficiency-related measures. How does the choice of insulation materials in new construction affect the building’s carbon footprint? What do five years of weatherization data tell us about GHG impacts of insulating existing buildings? What is the lifecycle carbon impact of using heat pumps to offset fossil fuel boiler heat when considering the electric grid, embodied carbon of new heat pumps, and heat pump fugitive emissions from refrigerant leaks? 

Many cities in New England and beyond have carbon neutrality goals and are actively addressing new construction to hit the goals. What about all the existing buildings? How will those be addressed to reduce energy and carbon? What creative enclosure approaches can be used to achieve these goals? Preservation of Affordable Housing has new construction projects in design to PHIUS standard. POAH also has rehab projects that never hit a passive house standard but go as deep as possible.
