As states and communities move towards building decarbonization and a carbon-free economy, the building energy sector and the best practices to make it more efficient must work together. Decarbonizing the building energy sector requires holistic market transformation to drive the deployment of technologies and products through increased consumer demand and robust workforce training. NEEP has previously produced numerous resources explaining how energy efficiency benefits consumers and detailing how new technology advancements make building decarbonization possible. This resource focuses on the third leg of the stool: the importance of building a pathway towards a robust and trained workforce. This resource aims to provide states, local jurisdictions, and program administrators with best practices for expanding their local workforce and creating training opportunities that will drive equity and inclusion in the building energy sector.
