Simulation of indoor and outdoor air quality and health impacts following installation of energy-efficient retrofits in a multifamily housing unit

•    Housing retrofits for energy efficiency can reduce energy use and related emissions.

•    When implementing energy-efficient retrofits, it is critical to quantify health effects.

•    Energy retrofits without ventilation worsened indoor air quality and health impacts.

•    Health costs from worsened indoor air quality far outweighed energy savings.
