Residential energy efficiency programs depend on the skills and professionalism of participating contractors to install a variety of energy-saving measures and interact with customers. Investments to develop workforce technical and business skills not only helps contractors succeed, but also sets expectations about a consistent definition of quality work. Some programs have partnered with organizations offering classroom training such as community colleges, universities, or weatherization training centers, while others have found apprenticeships offering accredited, on-the-job training to be a value. By investing in workforce development, programs have experienced enhanced assessment quality, more effective sales approaches, increased rates of conversion from assessment to upgrade, more comprehensive upgrades, more effective and efficient installation processes, improved quality control, and increased revenues for contractors. Supporting workforce development is one strategy to retain dependable and qualified contractors. Learn more about strategies to retain contractors here
