To earn the ENERGY STAR, a home must meet strict guidelines for energy efficiency set by the U.S. Environmental Protection Agency. These homes are at least 15% more energy efficient than homes built to the 2004 International Residential Code (IRC), and include additional energy-saving features that typically make them 20–30% more efficient than standard homes. Ranken began partnering with the EPA last year. Through this partnership RCDC agrees to affix an ENERGY STAR label on homes that are independently verified to meet program guidelines and to build at least one ENERGY STAR qualified home every 12 months to maintain their partnership. Through the Partnership Agreement process, the builder also selects a Home Energy Rater to work with to qualify their homes. RCDC had to submit the architectural plans to their home energy rater for review and analysis. The rater looked for key information on the plans and helped them choose the best combination of energy–efficient features to ensure that the home will earn the ENERGY STAR label when constructed. Throughout the construction process, the rater will perform a number of inspections and diagnostic tests to verify the proper installation of the selected energy–efficient features and overall energy performance of the home. When Bennett came to the site to check the installation of wall insulation he commented that the RCDC students had done a better job than he usually sees with most professional installers. "When these homes are sold, the new owners will enjoy lower energy bills from now on as a result of the work that our construction students are doing today," said John Wood, vice president for Student Success. "This Energy Star rating means that the heating and cooling bills will be 1/3 less than that of the average American home built today."
On December 5, Ryan Bennett from ASERUSA performed preliminary inspection of the two new homes being built on Evans Avenue for the V2.5 Energy Star rating.
