What is RESNET’s Carbon Rating Index?

Until now, the homebuilding industry has primarily relied on the combination of annual average emissions and the HERS Rating Index to measure the energy efficiency of new homes. While the HERS Rating Index is instrumental towards this effort, it does not paint the entire picture of carbon emissions. RESNET’s new Carbon Rating Index gives our industry reliable, accurate way to measure a home's energy usage and subsequent emissions. It signifies a critical shift towards decarbonization for the new construction industry and a major step in reaching our global climate goals.

Cooking with Induction - It’s Better than Cooking with Gas

Gas ovens are typically known for having better responsiveness and better heat control, but induction ovens actually heat faster than gas, are safer, and are better for the environment.
