Energy efficiency conferences 2026–2027

Tickets: USD 995 AEE members; USD 1,195 non-members; USD 1,095 eligible government and nonprofit non-members. Full conference includes sessions, keynotes, lunches, banquet, expo and technology breakfast. Check separately priced training and special activities.

Who's there: Per AEE's 2025 post-event report, roles break down as Energy Manager/Engineer 23%, Energy Consultant 22%, Executive (CEO/President/VP/Owner) 15%, Sustainability/Renewables Manager or Director 7%, Sales/Marketing 6%, Business Development 6%, Facilities Manager/Building Operator 2%, and Other/Student/Retired 19%. The crowd skews 45+ (62%) and male (77%). Sectors represented include commercial, industrial, institutional, municipal, government, utility, energy services, and education.

Room: 2025 actuals (Atlanta): 1,450 attendees, 86 exhibitors, 48 countries represented, 160 speakers, and 40 sessions across 10 tracks. Organizer's stated target for 2026 (Orlando): 2,000 attendees, 100 exhibitors, 60 countries represented.

Tickets: Advance rates through Oct 18, late rates unpublished: conference pass 1,399 dollars USGBC member / 1,599 dollars non-member; expo plus evening events 599 dollars; expo hall 169 dollars member, 525 dollars for non-exhibiting suppliers. Groups of 5-9 save 10%. Early bird ended Aug 7, saving 150-170 dollars per an archived table.

Who's there: Architects, contractors, engineers, building owners, and property managers; 79% work on building projects. The attending-company consultant block (Stok, Verdani, Brightworks, RE Tech, WAP) is competitors, not buyers. Real buyers (owners, REITs, asset managers, lenders) concentrate in the gated Finance Forum.

Room: '10,000+' is an unlabeled brand claim; trade press put LA 2025 at about 15,000 (unverified, the organizer site 403s fetchers). A low-five-figure room, with a much smaller reachable subset given only 2 expo days.

Worth knowing: The expo hall runs Wednesday-Thursday only, about 15 hours total, and Friday is a half-day and commercially dead. The co-located Sustainable Finance & Investing Forum runs Oct 20-21, application-gated, roughly 499 dollars in 2025 with 2026 pricing unpublished.

Tickets: Advance attendee badge registration is free through January 23, 2027. After that date online registrations cost $30, and any attendee badge taken out onsite also costs $30; onsite exhibitor badges cost $10. All prices are in USD; VAT or tax status is not stated. The AHR Education Program, covering industry seminars, panel discussions, rapid-fire new product presentations, for-credit courses, and live podcasts, is free with a show badge. ASHRAE Learning Institute sessions and the concurrent ASHRAE Winter Conference are not included and require separate paid registration.

Who's there: Organizer figures describe engineers, architects, facility managers, contractors, wholesalers, distributors, manufacturer's representatives, OEMs, and design/build professionals across residential, commercial, industrial, and institutional HVACR markets, plus 8,000 international visitors from more than 100 countries and 500-plus international exhibitors among 1,900-plus manufacturers and suppliers exhibiting. No seniority percentage breakdown or total attendee headcount is published on the official site.

Room: The organizer publishes 1,900-plus exhibiting manufacturers and suppliers, 500-plus international exhibitors, and 8,000 international visitors from more than 100 countries. A total attendee headcount, and whether these are 2027 targets or prior-show actuals, is not disclosed on the official site.

Worth knowing: Register by January 23, 2027 to get in free; badges bought later or picked up onsite cost $30. Show hours are 10am to 6pm on January 25 and 26 and 10am to 4pm on January 27. The co-located ASHRAE Winter Conference is a separate paid event, so budget for it if the technical program matters.
