Windows can account for up to 30% of a building’s heating and cooling energy loss, making them one of the most critical factors in achieving energy efficiency and occupant comfort. Advances in window technology—such as triple-pane glazing, innovative frame materials, and smart window systems—offer significant improvements in energy performance, noise reduction, and durability in extreme climates.
In this recorded roundtable hosted on Tuesday, August 26 by New Buildings Institute in partnership with the California Energy Design Assistance (CEDA) program, experts explore how fenestration design influences thermal bridging, lighting, and solar heat gain. Panelists also discuss adoption challenges, cost perceptions, and strategies for integrating high-performance windows into Passive House and other high-efficiency building standards.
Watch the recording to learn how advanced fenestration can benefit both building owners and occupants.

Lance Wheeler
Staff Scientist and Group Manager, National Renewable Energy Laboratory
Lance is a staff scientist and manager of the Materials Physics Group at National Renewable Energy Laboratory (NREL). He received his PhD in 2014 from the University of Minnesota where he focused his research on the development of quantum dots. Since joining NREL his work has remained in materials science with applications that span photovoltaics to neuromorphic computing. In 2017, he invented the world’s first thermochromic photovoltaic window. Since then, he has continued to develop the technology and engage in research on other building-integrated photovoltaic (BIPV) technologies and BIPV education.
