Multifamily Certifications

Investors and developers are increasingly concerned with the environmental and social impacts of their projects. Green building certifications provide a rigorous, concrete framework for ensuring that buildings are constructed as sustainably as possible. From navigating available incentives to verifying building practices, our team of experts is here to help you develop highly desirable, climate-friendly buildings. 


The Earth Advantage Difference

Earth Advantage multifamily certification is an excellent choice for developers looking to maximize the return-on-investment of sustainability measures implemented in their buildings. Achieving Earth Advantage certification can satisfy the requirements for incentives offered by Oregon Housing and Community Services (OHCS), Housing and Urban Development (HUD), Portland Housing Bureau and Bonneville Power Administration. Additionally, Earth Advantage multifamily certification is recognized by GRESB, the international benchmark assessing the environmental social and governance of properties. This means that Earth Advantage certification can be factored into the organization’s annual assessment for your property.

Expert Guidance, Modeling and Testing

We’ve created processes and materials to help our clients establish and achieve sustainability standards from design through construction and completion. Our field verification and performance testing ensures quality control by helping to support contractor accountability, which ultimately leads to better customer satisfaction.  

We know how to work effectively with professional design teams to facilitate an integrated design approach to create high performance buildings using the most cost-effective strategies. Our team addresses every project as an opportunity to deliver solutions that will make the project better with as little cost and complexity as possible. 

Certification Process

All Earth Advantage administered certification programs begin with a kick-off meeting to review and plan for the measures that will need to be completed for your project to earn certification. Projects will then undergo a series of inspections to verify that all measures have been properly implemented. Finally, we’ll review any energy modeling required by the program and issue the final reports needed to obtain final certification.
