"D3G was with us every step of the way.  The Green MIP program was new for everyone involved but D3G’s team explained the program requirements and helped us meet all the requirements cost-effectively. Throughout the green verification process, they were onsite answering questions and helping to ensure that we secured the NGBS Green Certification with no surprises.”

What Is The GRRP?

The Green and Resilient Retrofit Program, or GRRP, stems from the Inflation Reduction Act of 2022. This Act made $837 million in funds available to HUD-assisted properties through a series of loans and grants. This funding is available to projects seeking to improve energy, water, and electrical efficiency, enhance indoor air quality, and reduce emissions.

HUD has designated these funds under three specific cohorts: Elements, Leading Edge, and Comprehensive. This is a time-sensitive program, and we expect these funds to be allocated quickly. Our subject matter experts understand the requirements and reporting needed for your application and are ready to guide you through the best path forward. Reach out today to get started.
