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.

Pivotal Announces New APEX Simulation and Analysis Platform

Pivotal Energy Solutions, LLC, based in the Phoenix Arizona metropolitan area, has announced a new simulation solution targeting the residential new construction market. APEX, a simulation solution that utilizes the U.S. Department of Energy’s EnergyPlus simulation engine and OpenStudio-ERI calculation platform, enables the simulation of residential energy model data to generate energy rating index (ERI) and consumption results. APEX results may be used for a variety of purposes including eligibility for 45L tax credits, Fannie Mae and Freddie Mac mortgage-backed security offerings, performance-based energy code compliance, sustainability/ESG reporting, and incentive calculation for utility incentive programs.

APEX offers unique functionality for energy raters and modelers, utilities and other energy efficiency program sponsors, home builders, code officials, and downstream stakeholders to both validate energy models against specific program requirements and simulate those models using standard program reference homes and/or custom, program-specific user defined reference homes (UDRH’s). APEX’s input validation functionality – which can be run independently from simulation – performs automated checks on the energy model input values to ensure they not only fall within prescribed bounds but are also internally consistent with other home characteristics and specified values. This functionality enables energy raters and modelers to identify and correct issues with their energy models prior to simulation or submission to energy efficiency program administrators.

APEX supports the simulation of energy models using the U.S. Department of Energy’s EnergyPlus and OpenStudio-ERI simulation engine and calculation platform. The EnergyPlus/OpenStudio-ERI solution is an open-source offering from the National Renewable Energy Laboratory (NREL), meaning that the source code of the software is accessible to anyone to read, examine, and critique – proprietary simulators do not support the same level of transparency. The EnergyPlus/OpenStudio-ERI platform provides consistent, accurate results for an industry under increasing scrutiny due to the availability of 45L federal tax credits for homes meeting specific ERI targets and conforming to federal energy efficiency program requirements.

APEX’s support for standard reference homes and custom user defined reference homes (UDRH’s) also enables unique flexibility within the industry. Using a single energy model, APEX can perform simulations using any number of program-specific reference homes or custom UDRH’s. For example, eligibility for ENERGY STAR, DOE Zero Energy Ready, performance-based energy code compliance, and utility program incentives can all be determined through a single submission to APEX. Energy efficiency program developers and sponsors can also use APEX to enforce program requirements using the APEX input validation and custom UDRH capability to define energy efficiency targets and incentives as their programs evolve. APEX supports energy consumption and ERI calculation for ENERGY STAR, DOE ZERH, and virtually any utility and/or municipality performance-based program.

Bob Burns, co-founder of Pivotal, said, “We’re very excited to be offering this new solution to the industry. APEX enables utilities, builders, code officials, and downstream markets that rely on the modeled performance of homes to utilize a single, DOE-funded, open-source simulation engine, which we believe is a huge benefit to multiple stakeholders. APEX can serve as a ‘normalization tool’ to enable energy raters and modelers to use whichever modeling software they prefer while also providing a single, standard set of results generated by re-simulation of the original input data with EnergyPlus.”

The APEX simulation solution is currently integrated into Pivotal’s AXIS cloud-based platform used for the administration of and participation in a variety of “green” and energy efficient buildings programs. In the near future, APEX simulation and analysis solutions will also be offered as stand-alone cloud-based solution accessible through an application programming interface, or API, for easy integration into existing utility program infrastructure and back office applications.

Burns concluded, “APEX is a very powerful solution being introduced at exactly the right time to meet the residential new construction industry’s needs and support our country’s push toward a more sustainable future. We’re excited that we can play a role in the evolution of the industry.”
