2 16 26 ASHRAE Club Presentation trimmed

Date: February 16, 2026 Location: University of Cincinnati, ASHRAE Club Speaker: Chuck Lohre Pre-Meeting & Introduction Zach (ASHRAE President): "...We have Chuck Lohre. Chuck founded the Green Cincinnati Education Advocacy... he’s also leading the charge for Earth Day in Cincinnati this year... The plan is to have all 52 neighborhoods represented... Chuck is also a LEED AP and has worked on many LEED certified projects throughout his career." The Green Cincinnati Journey Chuck Lohre: "I got involved with the Green Cincinnati Education Advocacy... to get involved with the US Green Building Council. I was really impressed with its holistic look at the environment... I studied architecture down at the University of Kentucky, but I made my living in marketing. I gave a lot of tours of LEED buildings... The Steger Center here on UC's campus is very famous for its daylighting. The Cincinnati Zoo... those solar panels produce 20% of the electricity for the zoo. The City of Cincinnati fire stations... and the Cincinnati Public Schools. In 2019, I was invited by Raphaela Platow, the director of the Contemporary Arts Center (CAC), to help them reach their 2030 District goal of reducing energy by 50% by 2030." The Challenge: The Contemporary Arts Center (CAC) "Quite the challenging building. Zaha Hadid, very famous Iraqi architect... this was the year she won the Pritzker Prize. It’s a very large continuous pour, 11 stories high, that curves up from the street... the 'Urban Carpet.' I started tracking all their energy use... and found out this shocking number. A 250 EUI (Energy Use Intensity). That's about a hospital or a McDonald's. Typically, this building would use about 90 or 100 EUI. Immediately I could tell there must be a 'window open,' as I say. We found out about the Frankenthaler Climate Initiative... We got a $25,000 grant... and had HEAPY Engineering do a Level 3 Audit, a complete digital twin of the building. We learned that chilled water was being used even in the dead of winter." The Boulter House: A Living Laboratory "I tapped on my experience buying the Frank Lloyd Wright Boulter House in 2004... I used the house as a tool to teach my LEED classes. When we bought it... it had an EUI of 90. I proceeded to caulk everything... We found out there was nothing in the concrete block on the north side—it was just a screen door. We pumped foaming latex paint into the cavities... and that immediately caused our energy bills to go down 20%. I bring all this up because now I'm faced with the same problems with the Contemporary Arts Center. I finally learned, I think, all the secrets of the Boulter House after living there 15 years and literally licking every surface. Now I'm trying to understand: What are the secrets of the CAC?" The Detective Story: CAC’s Metabolism "We just had the wrap-up meetings... The air balancing uncovered incredible pressure drops across filters. It's a real detective story. The building has been running this inefficiently for its whole life... We’re burning the candle at both ends—chilling the air to dehumidify it, then heating it back up. Trane came up with an amazing idea. We have this huge amount of water coming into the building [from the district chilled water loop]... Why don't we tap into that? We'll take that water, once we've warmed it up doing our chilling needs, loop it through a heat exchanger, and use it as a heat source. It’s like putting electricity back into the grid, but with water." Earth Day & The Green Cincinnati Plan "I just wanted to conclude with my pitch... I'm Chair of the Earth Day event. We've moved it back to Washington Park. It's part of the Green Cincinnati Plan... a world-class environmental path to be much more resilient. We’re going to have the neighborhoods of Cincinnati arranged geographically... showing off their flags... talking about apartment recycling... connecting the plan to the people." Q&A: AI and The Future (A student asks about your takeaways from the audits and advice for young engineers.) Chuck Lohre: "I don't know if you guys use AI much, but I've been using AI to explain this building to me. I feed it 'Guide 36,' I give the AI these audits... and it comes back and tells me the action items. The engineers just accepted the list of talking points the AI spit out. You have to know enough to correct the hallucinations... but it taught me, a layman, about the system. The AI said, 'This is a big deal,' and I emphasized that in our meeting. It’s just teaching me... to ask the right questions."
