NGBS Analysis & Incentives

Comparing Green Home Building Rating Systems

The topic of equivalency often arises in discussions about green rating systems. While there are many elements of performance in green rating systems, energy performance is a key consideration.

The Multifamily Energy Performance Comparisons compare the energy performance of the ICC-700 National Green Building Standard ™ (NGBS) against other residential and commercial building codes, energy ratings, and green building certifications.

Cost and Stringency Comparison of 2012 National Green Building Standard™ ICC 700-2012, LEED-H 2008, and LEED v4 for Homes Design and Construction  evaluates the costs and technical requirements of bringing sample code-compliant production houses in different climate zones (Dallas, Denver, and Minneapolis/St. Paul) into compliance with three different green building rating systems. For each of three climate zones, the homes were specified to the minimum building code requirements of the IECC/IRC 2009 and IECC/IRC 2012.3, and the building codes provided the basis from which the incremental costs of green building standard compliance are measured.

Determining Equivalency: Comparison of the National Green Building Standard and LEED NC compares the scope and requirements of the National Green Building Standard (NGBS) and LEED for New Construction—the most popular green rating systems for multifamily communities 8+ stories in height.

NGBS vs. LEED-ND Comparison Report  evaluates the equivalency between 2012 ICC-700 National Green Building Standard (NGBS) Land Development criteria and the LEED 2009 for Neighborhood Development (LEED-ND) rating system. The report evaluates sustainability goals, process and maintenance of the rating systems, and verification and certification process and procedures.

AIA Cincinnati has also published a report comparing LEED for Homes and the National Green Building Standard . While the City of Cincinnati offers tax incentives for new and renovated homes certified to LEED, the local HBA requested that the NGBS be adopted for the same incentives. This report reviews both residential green building rating systems to determine if they are equivalent in performance and rigor of proof.

The Home Builders Association of Greater Chicago released a report  evaluating the additional costs of elevating three sample code-compliant, urban, residential building types in the City of Chicago into compliance with Chicago Green Homes Program (CGH), NGBS, and LEED-H.

Current Incentives Available for NGBS Green Certified Projects

Since ANSI approved the National Green Building Standard, municipalities and government officials have consistently deemed it to be on par or superior to other residential green rating systems. Home Innovation Research Labs has created a current summary of all known incentives across the country that specifically recognize certification to the NGBS.
