Three steps to decarbonizing buildings and scaling impact.
In the fight against climate change, the built environment presents both a challenge and an opportunity. Brendan Hermalyn, CEO and founder of Thalo Labs, is on a mission to transform how we measure and manage emissions in buildings.
During a recent event for the Xooglers in Climate hosted by Veronique Lafargue, Brendan shared key insights into the challenges, opportunities, and cutting-edge solutions for buildings decarbonization his company is developing.
The frustration of passive monitoring
Before founding Thalo Labs, Brendan spent years working with NASA, measuring greenhouse gases from space. Despite the technical brilliance of these efforts, he found the process deeply frustrating. "Measuring greenhouse gases from space is kind of one of the most depressing things you can do in sustainability because you can't touch it. Like the best thing you could do is send an email. It’s still leaking, right?" His dissatisfaction with merely observing the problem without being able to address it head-on drove him to create Thalo Labs.
A new vision for climate tech
Brendan has long rejected the idea that climate work is a niche or specialized field.
The core of Thalo Labs' offering is to make it easier and cheaper to measure emissions in real time. "I thought we could have a really interesting opportunity to bring down the cost and bring up the pervasiveness of measurement of greenhouse gases, and in so doing, that would allow us to do a much better job of managing them."
The built environment: A key source of emissions
In cities like NYC, the sheer scale of emissions comes from buildings.
Despite this massive source of emissions, there is very little regulation, and we often have no real sense of what’s being emitted. “Those systems on power plants can cost hundreds of thousands, if not millions, of dollars, and require people to look at them. But if you can make it cheaper to measure all these emissions coming out of the built environment, this really unlocks a new capability - not just knowing what's coming out, but also how you can save people money in doing it.”
This, Brendan explains, is the genesis of Thalo Labs.
From kitchen prototypes to large-scale deployments
What began as kitchen experiments has now grown into a full-fledged operation. Thalo Labs has already helped remediate over 80,000 metric tons of CO₂ equivalent from buildings, a figure larger than many climate investment portfolios. "And we're on pace to at least 10x that in the next year, which is really exciting for us."
Go-to-Market strategy: focus and agility.
Breaking into the real estate sector is no easy feat. Brendan is candid about the difficulties of selling into this industry, where many stakeholders have competing priorities. “Everybody will probably tell you that selling into real estate is really hard, and they're 100% correct because there’s a lot of different stakeholders, and they don’t all look the same. Even two buildings can have totally different management structures.”
The company’s go-to-market strategy has been to approach early customers with a highly targeted approach, starting with real estate investment trusts (REITs), which manage their own buildings and have ESG goals. Thalo Labs’ strategy has followed a “stair-step pattern,” learning from each early deployment to improve their product and refine their approach.
As they’ve moved further into the market, Thalo Labs has begun targeting larger clients with complex needs. Their first major contract was with a Fortune 50 bank, which pushed the team to grow quickly and professionally.
Three steps to decarbonization: Brendan’s manifesto
Brendan outlines a three-step approach for transforming the built environment:
Target major emitters: Start by identifying and addressing the highest-emission systems in buildings, such as large boilers and refrigerant systems. Tackling these high-impact sources offers the greatest initial reduction.
Deploy affordable sensing systems: Once primary emitters are managed, install cost-effective sensors across all other systems to collect comprehensive operational data at scale.
Use data to drive change: With these systems in place, Thalo Labs aims to create the most comprehensive data set on how buildings operate and emit carbon.
A new era of building management
The long-term vision for Thalo Labs is to transform the built environment into a driver of sustainability. Brendan envisions a future where buildings don’t just reduce emissions but actively capture and store carbon, turning them into carbon sinks.
As the world grapples with the complexities of climate change, Brendan’s journey shows how taking the leap into climate tech can lead to real, measurable impact.
