Thalo Labs' HVAC Copilot supports building decarbonization by helping properties meet LL97 requirements through emissions reduction and system optimization. It reduces Scope 1 emissions by detecting methane leaks and refrigerant losses in combustion and refrigerant-based HVAC systems, and lowers Scope 2 emissions by identifying inefficiencies that drive excess energy use, such as undercharged refrigerant loops and improper operating modes.
