While insulation and airtightness are critical elements of a high performance building, they also can significantly increase the risk of health and moisture failure issues. In addition, if using high "embodied carbon" impact materials then high performance buildings can have a higher net carbon impact by 2050 than conventional buildings. Come join us to learn how to create truly healthy, durable, comfortable, and low carbon impact buildings. Join Kristof as he interviews Lucas Johnson in a discussion about the impacts of insulation material decisions.Lucas is a building scientist who has worked as a builder, utility program manager, enclosure systems consultant, and clean tech venture capital consultant to deliver Zero Net Energy, Passive House, Living Future, and even two of his own standards: SUN Buildings and Active House. Lucas holds a degree in Physicochemical Biology as well as a Master of Environmental Science and Lucas JohnsonEcoEntrepreneurship.
