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.

The program has been expanded recently. In 2010, Greenville Utilities and the City of Greenville joined together to utilize a $777,600 Federal Stimulus grant to improve energy efficiency. GUC and City of Greenville staff worked collaboratively to determine the best way to use these Energy Efficiency and Conservation Block Grant (EECBG) funds, with an eye towards enhancing programs that currently exist. E-300 is one of those programs.

The existing E-300 program will remain in place and unchanged. In addition, E-300 Plus, which holds homes to even higher standards of efficiency, is now also an option.

A total of $140,000 has been allocated to the program. Both the builder and the purchaser receive incentive funds that are based on three tiers ($500, $1,000 and $2,000) of efficiency. Factors include solar orientation, framing/insulation, building air-tightness, HVAC system, foam sheathing, insulation, foundation, and efficient water fixtures and landscaping.
