Changes for the 2015 Edition

The 2015 edition incorporates changes that better align the NGBS with the I-codes, expands the application of innovative practices and builds upon years of building and certifying to NGBS. Some of the more notable updates include:

• Substantial revisions to the Energy Efficiency chapter, which now has more stringent rating levels based upon whole-house energy savings that are above the 2015 International Energy Conservation Code.
• New criteria for measuring water usage that focus on appliance and fixture performance instead of third-party water efficiency labels.
• Mandatory installation of carbon monoxide alarms for all buildings, regardless of level of certification or local code.
• Revamped stormwater management options that encourage low-impact development practices.
• Greater emphasis on and recognition of multi-modal transportation options including bicycle parking, pedestrian connectivity, proximity to transit and electric-vehicle charging.
• New references in the Resource Efficiency chapter on innovative practices for environmental product declarations for both specific and industry-wide products.

This latest edition includes everything needed to design, construct or remodel any residential project to the most current sustainable and green building criteria available - all under one roof!
