Green Communities

Buildings are responsible for nearly 40% of emissions globally, giving us the power to slow the pace of climate change through thoughtful building design, construction, and operation.

Twenty years ago, we launched the nation’s only green building program created with and for the affordable housing sector. Today, ours is the most widely adopted criteria in the sector with close to 200,000 certified units nationwide and 29 states — along with the District of Columbia, Puerto Rico, Chicago, and New York — now requiring or incentivizing developers seeking funding to meet our standards.

Building Green is just one pillar of our comprehensive response to climate change. Our Building Resilient Futures team is also leading the industry in Climate Risk Reduction and Equitable Decarbonization.

2026 Green Communities Criteria: 20 Years Strong

The one-and-only green building standard designed specifically for affordable housing, Enterprise Green Communities, undergoes a refresh every five years. We’re excited to introduce this next iteration of the program, the 20th anniversary edition, and its three important themes: energy, resilience, and health.

A big thank-you to the many developers, architects, technical experts, and others who shared feedback during the recent public comment period. With that valuable input, we’re gearing up for a full roll-out in the coming year. Use the link below to be among the first to access the new criteria.

In addition to our industry-leading standards, we provide grants and technical assistance to advance high-quality affordable housing development. We also partner with researchers to improve the health and quality of indoor environments, and engage with federal, state, and local leaders on polices that further green affordable housing development.

Many of those most vulnerable to climate change live in socially and economically disadvantaged communities, which is why we’re committed to advancing racial equity and supporting upward mobility. All of our capital tools, technical assistance, programs, and policy solutions are designed to make affordable housing in communities across America healthier and more prepared to withstand severe weather events.

Green Communities Criteria

Our cost-effective, above-code green building program includes integrative design, site considerations, water, energy, healthy building, operations/maintenance, and resident engagement. It is applicable for new construction, substantial and moderate rehabilitation, historic properties, and adaptive reuse across both multifamily and single-family affordable housing projects.

In partnership with the International Well Building Institute and their WELL Building Standard, we’ve leveraged the best of these impactful programs, and created a path for affordable housing developments in the United States to create best-in-class healthy, efficient, and environmentally responsible homes. Projects that achieve certification with the 2020 Criteria are recognized as certified under both Enterprise Green Communities and the WELL Building Standard.

Making Zero Emissions Possible

Enterprise recently modified its Green Communities criteria to simplify how developers pursuing our highest level of certification, Certification Plus, can align their projects with the Department of Energy’s newly released National Definition of Zero-Emission Building. As a result, housing providers now have more opportunities to access valuable funding and incentives through the Inflation Reduction Act while supporting energy and emissions goals for the sector. In another recent update, the criteria now offer housing providers embarking on deep energy retrofits a clear course to Certification Plus, giving existing buildings an on-ramp for IRA opportunities, as well as funding through the Low-Income Housing Tax Credit and the Community Development Block Grant – Disaster Recovery.

Advancing Green Affordable Housing Development

In addition to our industry-leading standards, we partner with researchers and government organizations to advance the field of green affordable housing development.

Our practice-informed guidance leverages more than four decades of experience in both successful advocacy at all levels of government and program execution to create actionable policies. At the national level, we work with affordable housing institutions including HUD, Freddie Mac, and Fannie Mae to associate more favorable financial incentives for housing that achieves green building standards.

Our team is always working to deepen our understanding of how green building, policies, and practices can help expand opportunity in communities nationwide. Throughout our history, we have partnered with a variety of leading institutions on research projects designed to advance the field, for example, “Studying Optimal Ventilation for Environmental Indoor Air Quality” with the National Center for Healthy Housing.

Looking to Implement a Green Program in Your State?

Twenty-nine states currently include Green Communities Criteria as part of their Qualified Action Plans for the distribution of Low-Income Housing Tax Credits — and many more include some level of green and/or energy incentive(s). We provide guidance on best practices to housing finance agencies and other organizations to help continually move the needle on green building and work nationwide with coalition partners to advance green building across the country. Learn more about the certification offerings in your state’s QAP.
