Passive house has become synonymous with the rapidly arriving new normal for our homes and buildings and offers layers of positive outcomes. Thermal comfort, IAQ/IEQ, durability, and low energy use are typically the incentives for owners, architects, builders and trades. As it turns out, there may be broader societal benefits tied to thoughtfully managing heat flows in and out of a building as well. Good ol’ thermodynamics isn’t getting the flashy attention of solar PV, wind turbines and batteries, but the demand side may well be where we win this fight to protect ourselves and our planet from the worst, most devastating impacts of the climate crisis.

Join Kristof in this wide-ranging conversation with Lisa White, the Co-Executive Director of Phius, where they unpack the positive ripple-out impacts that passive buildings have on our energy grids, and our decarbonization efforts. Seen holistically, buildings are a powerful enabling technology for the ongoing energy transition away from fossil fuels to renewable sources of energy. Starting with a perspective on the current state of the grid and its ongoing evolution, the conversation here positions passive buildings in relation to the decline of the fossil fuel era and the dominance of renewables.

Lisa White is the Co-Director and a technical lead for Phius.  

Ms. White has been with Phius since 2012. She led the building certification review team for seven years and is an instructor for Certified Passive House Consultant (CPHC®) training and WUFI® Passive energy modeling software training. She holds a degree in Environmental Sustainability with a minor in Architecture from the University of Illinois at Urbana-Champaign, and a Master’s in Energy Engineering from the University of Illinois at Chicago.

Ms. White has a strong understanding of high-performance building design and how this is integral to the transition to a renewable energy grid. Her Masters’ thesis posed the question “What do Net Zero Buildings Cost the Grid?”, combining the concepts behind how building loads are shaped, how design techniques can alter that shape, and how that ultimately impacts the electricity generation resources needed to meet the load – all while considering the shift to more intermittent, renewable energy resources. Ultimately, this research concludes that energy conservation and demand response in buildings is a critical up-front investment to facilitate this transition.

At Phius, White works on the development of new and existing professional training courses and has delivered professional training to more than 800 students. She has taught introductory and advanced seminars at professional conferences and universities nationwide, including guest lecturing at the Harvard Extension School. She is a longtime member of Phius’ technical committee and was instrumental in the development of the Phius+ 2015 Climate-Specific Passive Building standard, followed by the 2018 and 2021 updates. Alongside standards development and research, White works directly with the Fraunhofer Institute of Building Physics to develop and implement new key features into the WUFI Passive energy modeling software that Phius uses for passive building certification. While in her previous role as Certification Manager, Ms. White reviewed and provided feedback on energy models, drawings, details, planned mechanical systems, etc. to more than 500 project teams working on passive building designs across the world.

Ms. White has written and co-authored many publications, the most recent being a cover-featured article in the ASHRAE High Performing Buildings magazine. She has presented at numerous national and international conferences on topics related to grid-friendly buildings, assessing resiliency and passive survivability, measured data for high performance and net zero buildings.
