Kelvin: Decarbonized HVAC Solutions Company Closes $30 Million In Series A

By Noah Long ● Jun 5, 2023

Kelvin – a pioneer in intelligent, decarbonized HVAC solutions for legacy buildings – recently announced the closing of $30 million in Series A funding. The rebranding from Radiator Labs to Kelvin reflects the company’s growth beyond radiators, including expansion into the US and European markets and targeting older building decarbonization where emissions reduction is a vital climate goal.

The Series A funding round was led by climate-focused venture capital firm 2150, with participation from the Schmidt Family Foundation, the Partnership Fund for NYC, and several previous investors. The funds will be used to hire talent and build a scalable platform for accelerating the adoption of economically and environmentally sustainable HVAC options worldwide.

Kelvin’s scope broadened to include other decarbonized HVAC applications, such as heat pump and thermal battery systems, enabling legacy buildings to electrify up to 80% of their heating needs at under 10% of traditional full electrification costs. Like the Cozy, Kelvin’s first product, these solutions are also easily installed through a subscription agreement, making them affordable for all buildings regardless of access to capital.

Kelvin’s flagship product the Cozy is an insulated radiator cover that enhances heating efficiency by preventing overheating and fuel wastage. And implementing Cozys throughout a building can result in up to 45% lower heating costs, increased comfort for residents, and decreased building emissions. The Cozy was installed in more than four thousand apartments across the northeastern United States and has undergone extensive independent validation by multiple agencies.

Kelvin offers a no-money-down subscription and removes capital barriers to decarbonization for all communities and promotes a financially-driven transition, especially benefiting lower-income communities. And as a qualified technology for the Inflation Reduction Act’s investment tax credit and other state and utility energy efficiency incentives, Kelvin’s decarbonization and efficiency solutions help buildings comply with local emissions, energy efficiency, and electrification regulations, including New York City’s Local Law 97.

Since 2011, Kelvin sold over 15,000 intelligent HVAC solutions to a diverse range of customers, including universities, large real estate portfolios, COOPs, city agencies, and housing authorities.

KEY QUOTES:

“Our new identity as Kelvin symbolizes the next phase of our broader mission: to provide energy-efficient temperature control that benefits building owners, tenants, and the larger communities they serve.
