Science-based guidance helps building professionals reduce risks from Legionella and wildfire smoke. ATLANTA (11 August 2026) – ASHRAE is highlighting its technical resources to support building professionals in addressing global environmental and public health challenges, including wildfire smoke, extreme heat and Legionella risk.
As communities in North America, Europe and other regions face these changing conditions, the Society continues to provide science-based guidance that supports healthier, safer and more resilient buildings.
Although these events arise from different environmental conditions, they share the challenge of maintaining healthy indoor environments through effective design, operation and maintenance of building systems.
From protecting occupants against smoke ingress during wildfires to implementing comprehensive water management programmes that reduce the risk of Legionella growth, building professionals play a crucial role in protecting public health.
‘Buildings worldwide face increasingly complex environmental and health challenges,’ said 2026-27 ASHRAE President Sarah Maston, PE, BCxP, LEED AP BD+C. ‘Whether responding to prolonged heat, wildfire smoke or water quality concerns, resilient buildings begin with proactive planning and sound engineering.’
