Home Innovation Research Labs Celebrates Certification of 500,000th Green Home in the NGBS Green Program

Home Innovation Research Labs proudly announces a significant milestone in sustainable housing with the certification of the 500,000th green home to the National Green Building Standard (NGBS). The project that helped NGBS Green reach this point was Bluebird, a permanent supportive housing facility in Boulder, CO. The NGBS Green Verifier on the project was Sarah Hong, PE, Energy Project Manager for Group14 Engineering, PBC.

The 500,000th NGBS Green Certified Home, Bluebird, is a housing tax credit project developed by Element Properties to provide permanent supportive housing to those experiencing homelessness. 

Many of the design features that were pursued to address sustainability, energy + water efficiency, and occupant health and well-being aligned with NGBS principles, allowing the building to achieve NGBS Silver certification. The project also has an energy-efficient design that achieves an EUI of 31.4 kbtu/SF/year – 21% below Colorado’s 2030 benchmarking target. Key features include an above-code envelope, ENERGY STAR appliances, WaterSense-equivalent plumbing fixtures, and high-efficiency cold-climate packaged heat pumps. A central ERV was installed for ventilation, which not only reduces energy consumption, but also provides improved climate resilience and indoor air quality with MERV 13+ filters that are able to capture airborne particulates and pollutants resulting from regional wildfires. 

In consideration of its resident population, the building has been designed with trauma-informed design strategies to provide a safe, supportive space for people who have been homeless for years. The site is also located in a central area of Boulder with easy access to bike paths, walking trails, and public transportation, and each resident gets a free bus pass. There is also an onsite solar PV system that not only reduces the energy cost burden on tenants but also reduces the building's greenhouse gas emissions by 12%. The building was designed by Shopworks Architecture and built by I-Kota.

The NGBS Green program, administered by Home Innovation Research Labs, is a comprehensive and rigorous certification that recognizes homes for their commitment to sustainability. Achieving this milestone highlights the growing commitment of homeowners, builders, and communities across the nation to create more sustainable and resilient living spaces. 

"We are thrilled to reach the monumental achievement of certifying the 500,000th green home in the NGBS Green program," said Michelle Foster, VP of Sustainability at Home Innovation Research Labs. " This accomplishment underscores the industry’s commitment to the design and construction of sustainable buildings that have a smaller impact on the planet and a big impact on the resident’s lives. Bluebird also showcases the positive impact that sustainable housing can have on our communities."

The NGBS Green program provides a framework for builders and developers to construct homes that are not only energy-efficient but also healthier for occupants and kinder to the environment. The certification process evaluates various aspects of a home, including energy performance, water usage, indoor air quality, and resource efficiency. By meeting the stringent criteria set forth by the NGBS Green program, homeowners can be confident that their homes are contributing to a more sustainable and resilient future.
