About cosy.green

cosy.green addresses inefficiencies in residential heating systems, where a significant majority are improperly adjusted, leading to substantial energy waste and CO2 emissions. The company has developed a solution that integrates smart thermostats with artificial intelligence to optimize heating control in buildings.

Read full description

This technology enables off-the-shelf thermostats to communicate directly with a building's central heating plant. The system uses AI-powered radiator control to deliver personalized comfort for tenants while simultaneously reducing energy consumption. By constantly monitoring and analyzing heating usage, the platform identifies opportunities for energy savings, which helps lower heating bills for residents and reduces the property's carbon footprint.

The primary clients are housing companies, property managers, and housing cooperatives. These entities are facing pressure to meet sustainability objectives and adhere to emissions regulations. By implementing green's solution, they can improve their property's Energy Performance Certificate (EPC) rating, which helps preserve the asset's market value. The business model appears to be B2B, providing a service that enhances tenant satisfaction through lower bills and improved comfort, while helping property owners meet environmental and financial goals.
