This page rounds up nine events worth knowing about, with dates, locations, and enough context to decide which ones fit your schedule. The ASHRAE Annual Conference in Austin runs June 27 through July 1 and is the clearest anchor for anyone focused on standards, energy efficiency, or technical networking in the industry. Earlier in the month, the Indoor Air Conference in Singapore draws a more research-oriented crowd with a focus on ventilation science and air quality data. If you're planning a Q2 or Q3 pipeline push, several of these events cluster in the first two weeks of June, which makes back-to-back attendance realistic without a lot of extra travel. Use this page to map out what's relevant before registration deadlines close.
