Design guidance: residential electrification

Resources for residential building owners, designers, contractors, and electrification program developers

Buildings are a major source of greenhouse gas emissions. Fully electrifying them using clean electricity helps us fight climate change. How can you minimize construction costs and infrastructure upgrades while maximizing energy cost savings and providing high-quality building environments, appliance features and performance? Here are some helpful technical resources and case studies to assist you in the development of electrification plans while maintaining safety and resiliency.
