2025-2026 Super Savers
There’s a reason why the New York Times said that “the Cozy’s victory is understandable. It addresses a problem that has afflicted New Yorkers since the early 1900s”.
That problem? Overheated buildings and residents having to open their windows. Opening windows in mid-winter is a legacy problem that traces back to the Spanish Influenza of 1918. The flu was believed to be an airborne disease, and so the NYC Board of Health ordered tenants to keep their windows open to curb the spread of disease. This led to architects and engineers outfitting buildings with “oversized” radiators so that residents could stay warm even with the windows open.
What solved a problem in 1918 has become the problem today. Buildings emit nearly 70% of GHGs in large cities, and a large part of that is from building heating. This is where Kelvin steps in. Kelvin is here to retrofit radiators so that residents no longer have to open their windows, and instead can adjust their radiator heat output like a thermostat through the Cozy. This provides not only resident comfort, but heating cost savings.
Just before the start of this heating season, we ran an analysis to see how our customers’ buildings performed this past 2025-26 heating season. We wanted to make sure that our customers were maximizing their savings and that residents were getting the full benefits of their Cozys, and what we found was that many of our customers saw their best savings last year.

What’s next?
These buildings were built nearly a century ago, but that doesn’t mean that they have to operate in the past. As made evident with these buildings, big savings can happen without having to do gut renovations and boiler replacements. These owners invested in their long-term savings and resident comfort, and are quickly seeing the benefits of doing so.
