Chicago Adopts Energy Transformation Code: NGBS Green Certification Recognized as Alternative Compliance Option

Chicago's City Council has passed an amended version of the 2021 International Energy Conservation Code (IECC) — titled the Chicago Energy Transformation Code — that requires strong energy efficiency and electrification for new buildings. The goal of this new code is to align commercial real estate with Chicago's climate action plan, which aims to reduce carbon emissions to 62% below 2017 levels by 2040.

The new code recognizes two third-party certifications as alternative compliance pathways: (1) 2020 NGBS Green certification at the Gold or Emerald levels; and (2) 2021 Passive House Institute U.S. (PHIUS). The City noted that these programs were selected for their rigorous pre-construction reviews and post-construction verification by independent third-party reviewers.

Inflation Reduction Act (IRA): 179D Tax Deduction for Energy Efficient Commercial Buildings

The Inflation Reduction Act of 2022 (IRA) was signed into law by President Joe Biden on August 16, 2022.

This legislation includes significant investment in energy efficiency and clean energy technology. For the next several months, we will feature an element of the legislation related to the built environment.

The IRA significantly expanded the 179D tax deduction for energy efficient commercial buildings from $1.80 per square foot to a sliding scale of $2.50-$5.00 per square foot, with new pathways for existing building retrofits to access the deduction. New construction must achieve 25-50% over ASHRAE 90.1; retrofit projects must demonstrate 25-50% improvement over existing building energy use intensity. "Bonus" incentives are available for projects meeting prevailing wage and apprenticeship requirements.

Product Spotlight

In each issue of Insider Update, Home Innovation profiles products that can help builders achieve points toward NGBS Green Certification. To browse all NGBS Green Certified products, visit the online directory.

Corzan Piping Systems

Corzan and Corzan HP Piping Systems are made from a non-corrosive durable chlorinated polyvinyl chloride (CPVC) technology that makes them chemically inert to most mineral acids, bases, and salts. CPVC was first commercialized by Lubrizol in the early 1960s and has since proven its value in a variety of industrial applications where high use temperature and corrosion resistance are desirable.

These products are certified under the Product Life Cycle Assessment practice (610.1.2.1), and points are available when Corzan is chosen over another copper-based water distribution pipe based on LCA findings.

NGBS and the Artificial Turf Debate

Use of artificial turf in multifamily communities has been a source of controversy, with industry leaders debating its environmental impact and product regulation. Is artificial turf an innovative green practice that enhances both environmental and athletic performance, or is natural turf the better landscaping material that should not be replaced? Read Damiyen's blog to explore the issues surrounding artificial turf and its inclusion within the NGBS.

Resiliency and Sustainability

Resilience has always been a huge part of sustainability, but with climate change impacts being ever more apparent, we can expect a roller-coaster of flood, wind, fire, and other weather events to stun us more frequency. It's high time we rethink resilience and sustainability as one entity and include both in our construction practices.

Why is it Important that WRI is Included within an I-Code?

The 2020 NGBS includes a performance path for residential builders and developers to demonstrate water efficiency. The Water Rating Index (WRI) – included as an appendix within the standard – is a methodology by which a 0 to 100 score is assessed for a property's total indoor and outdoor water use, compared to baseline conditions. The inclusion of WRI within an I-code lends credibility to water performance ratings and raises their prominence in the market. Read Cindy's blog to learn more.
