1. National Green Building Standard™
ICC/ASHRAE

2. Green Building as a Home Building System
Starts with Holistic Planning
Evaluate Options across all Work Stages and Tasks
Examine for benefits across multiple practices
Involve all parties
Determine the levels of performance
Document products and practices

3. Holistic Application of Multiple Systems
Recognizes the inter-related nature of each system
Emphasizes a balanced approach to each system
Emphasis on comfort, health, efficiency
Provides for multiple paths to compliance
Lot Design
Resource Efficiency
Energy Efficiency
Indoor Air Quality
The Standard defines green building practices in 6 categories:
Lot Design and Development
Resource Efficiency
Energy Efficiency
Water Efficiency
Indoor Air Quality
Operation, Maintenance, Building Owner Education
Once the mandatory practices are included, a builder can select from the optional green building practices to comprise the additional points required for certification to the Standard. Because only one-third of points are mandatory, the Standard provides builders a great deal of flexibility in the path to building a green home. However, that in no way means that the Standard is not rigorous in its measure of performance.
Operation & Maintenance
Water Efficiency

4. National Green Building Standard
Recently Approved March 2016
Collaboration between ICC, ASHRAE and NAHB
First version approved in 2008
First green rating system to become an American National Standards Institute (ANSI) approved consensus standard
Approved by the American National Standards Institute (ANSI) in January 2009, the National Green Building Standard is a residential green building rating system. The Standard goes beyond the requirements of the International Residential Code to set green baselines for all new residential construction, development, and remodeling projects.

5. Key Elements ANSI-approved consensus standard
Free downloadable Green Scoring Tool
Third-party verification of all claimed practices
Applies to ALL residential projects – Land Development, General Construction, Multifamily, Remodeling
Mandatory items in each category
Multiple practices available for flexibility
Requires progressively higher levels of environmental performance in every category to obtain higher levels of green certification
At this time, there are a number of green building rating systems available for the residential construction industry. However, there are five key elements that distinguish the National Green Building Standard from all others.
First, the Standard is the only true consensus standard having been approved by ANSI in January 2009.
Second, there is a free, web-based application called the Green Scoring Tool that is available to all builders, remodelers, and developers that want to explore how their projects can use green building practices. This means there’s no need for even the most novice green builder to hire a pricey team of consultants to get started building green.
Third, the Standard requires uncompromising independent, third-party verification for all points claimed. No affidavits or self-certifications allowed.
Fourth, the Standard applies to all residential projects, including single-family, multifamily, remodeling projects, and land development.
Last, for a home to move up from Bronze, to Silver, to Gold, to Emerald the home must perform better in every category. The highest possible certification level of a home is based on the lowest rating it scores in any one category.
Bronze
Silver
Gold
Emerald

11. 3 Regions with Greatest Green Opportunity by Builders and Remodelers
Pacific: #1
81% builders
85% remodelers
West North Central: #2
76% builders
79% remodelers
New England: #3
75% builders
64% remodelers
Ranking is the same for builders and remodelers, but more builders see an opportunity in New England than remodelers
Pacific (81% builders / 85% remodelers)
West North Central (76% builders / 79% remodelers)
New England (75% builders / 64% remodelers)
New England is more typical of the rest of the results than the top two regions: Fewer remodelers see opportunity for green than builders in 6 out of 9 regions – biggest gaps in the South Atlantic (21% gap) and Mid Atlantic (26% gap)

12. Firms Dedicated to Green Will Increase Dramatically by 2016
Dedicated to Green: 90% of their projects are green
Remodeler have a lower share of green in their projects currently, but their rate of growth is nearly triple, compared to nearly double for builders
Supported by survey of early green adopters in Spring 2011 – 20% of them were doing 75% or more green work in 2011, but 80% expect to be at that level of green by 2016
