E-300: Setting the Standard for Energy Efficient Building Practices

Our E-300 program has promoted energy efficient construction for more than 30 years and is the longest running program of its kind in the nation. More than 50 percent of new homes in our service area utilize the program, which helps increase energy efficiency. Since the program began in 1978, over 12,000 homes and commercial structures have passed the rigorous E-300 standards. Builders, insulators, heating and air conditioning contractors and Pitt Community College instructors participate in the program. Using a systems approach, the E-300 program incorporates the most up-to-date, cost-effective technologies, procedures, materials, design, and equipment recommendations for building energy-efficient homes.

To meet E-300 program requirements, builders and homeowners submit plans for evaluation by an Energy Specialist. Recommendations for insulation and other energy-saving features are made on the basis of a computerized load calculation. If the structure’s heat loss falls within acceptable levels, the house qualifies for the E-300 award. To verify installation of energy efficient features, the structure is carefully inspected at several stages of construction.
