About Kelvin Stock

Kelvin is an energy management and electrification platform for radiator-heated buildings. The Radiator Labs system uses smart thermostatic radiator enclosures (Cozys) networked to central heating controls to eliminate fuel waste, reduce building emissions, and improve tenant comfort. Its hybrid electrification platform enables buildings to electrify 60-80% of their space-heating requirements for 20% of the cost of typical electrification alternatives. Buildings outfitted with the Radiator Labs Hybrid Electrification technology can be programmed to optimize heating fuel sources based on energy pricing, building energy letter grades, and carbon fines. The Radiator Labs hybrid electrification technology would enable all radiator-heated buildings to meet NYC 2030 emission caps at a significantly reduced cost. Radiator Labs' technology has been validated by NYSERDA to save 25.5%, on average, in heating costs and was included in the 2019 New York State Technical Resource Manual (TRM). Radiator Labs is a recipient of the 2012 MIT Clean energy prize, the 2014 Popular Science Innovation Award, the 2014 Verizon Powerful Answers Award, the 2017 Architizer A+ Award, The 1776 Challenge Cup, and the 2020 New York City Department of Buildings Carbon Neutrality Innovation Challenge. Radiator Labs is also a member of the inaugural cohort of The Clean Fight, powered by NYSERDA and the New Energy Nexus.
