When DeShawn W. retired from a 21-year career in the U.S. Navy, he knew he wanted to keep serving his community. In 2019, the Detroit native launched his small business, Duke Investments & Associates, which helps connect the community to vital services in construction, medical and information technology. Through his work, he uncovered a critical need in Detroit: thousands of older homes across the city aren’t energy efficient, and there aren’t enough certified contractors to connect families to the upgrades that could save them money on their energy bills.

He found his new opportunity to make an impact through the DTE Energy Efficiency Academy. The Academy, launched in 2023 in partnership with Walker-Miller Energy Services, provides paid, hands-on training to help participants earn nationally recognized certifications in building science, insulation, HVAC and electrical work.
“There are so many Detroit homes that need upgrades to their HVAC systems, windows or insulation,” DeShawn explained. “The more contractors certified to do energy efficiency assessments in these houses, the better we can help families save money. This program is changing neighborhoods.”
Through the Energy Efficiency Academy, DeShawn earned multiple Building Performance Institute (BPI) certifications, including Building Analyst Technician and Healthy Housing Principles. These credentials opened the door to conducting energy and weatherization assessments across Metro Detroit. For homeowners, those assessments can unlock rebates to upgrade HVAC systems, insulation and electrical work, at no cost for eligible households.
“Getting these certifications was something I never imagined and it’s been heaven-sent,” said DeShawn. “The program gave me confidence and the tools to grow my business while helping families make their homes more energy efficient. When households can save on monthly heating and cooling costs, they have more money for groceries, childcare or saving for the future, and making this type of difference for families keeps me motivated in my work.”
DeShawn was part of a class of 20 participants and today, he continues to work with other graduates, contractors and DTE to bring energy-efficient solutions to Detroit families.

His story is one of many showing how the Energy Efficiency Academy is turning skills into careers, and careers into community impact.
