The 2019 Field Guide is the first to combine both HVAC and lighting resources in one easy-to-use handbook. You’ll find technical information to help with specific projects, as well as resources to support upcoming workshops, contact lists, and tips and ideas to inspire future projects. The Field Guide is a tool to help your business thrive. The incentive information included in this 2019 Field Guide is no longer up-to-date. Please refer to the program offering pages for current information or contact your regional field specialist or local utility.
