We see the clear connection between energy upgrades and health via improvements including better ventilation, quieter HVAC systems, and thermal stability. But we've yet to see the specific health benefits (and challenges) associated with electrification. How can we improve our carbon footprint and hit the 2050 climate goals while simultaneously making tenants happier and healthier? This session will detail factors contributing to optimal human health, both indoors and outdoors in the built environment; study emerging data from Harvard’s Ventilation/IAQ project and its hoped-for effect on affordable housing developers, policymakers, and capital providers; advise on hazardous chemicals and healthier choices of materials specifically related to electrification; and lay out key electrification strategies for protecting health in a socially equitable and cost-effective manner.
