3. What is Build Green NM Operates under the Foundation for Living (Formerly Foundation for Building) a 501 c 3 non profit Provides 3 rd party certification of High Performance Homes We have certified about 4070 homes in the State of NM Local administration of program for the State of NM Education for Builders, Homeowners and affiliated industries Program for both New and Existing homes Educate consumers to encourage wise purchasing decisions in home buying and remodeling Advocate for voluntary High Performance Standards

4. Program Base 2009 National Green Building Standard ICC - 700 2010 ASHRAE 62.2 2015 ICC IECC

5. 2014 Revision Accomplishments Narrowed the breadth of the program (eliminated most of the subjective practices, hard to verify (timing) not relevant to the southwest) Raised the Bar for Energy and Water Developed a WERS Index for indoor water use Focus on Ventilation in IAQ Reduced the paperwork which reduced costs associated with certification More marketing and consumer friendly certificate

6. Green Building is a look into the future of codes…available today BGNM Certified Gold Level HERS 49 before PV HERS 22 With PV WERS 58

7. Raise the Bar for Energy Bronze LevelHERS 65 Silver LevelHERS 58 Gold Level HERS 51-55 (based on CZ) Emerald Level 20% below Gold Level

8. Raise the Bar for Water Efficiency Performance Path INDOOR WATER USE NEW!WERS Index Compares Water Fixtures and Water using appliances Installed vs. Industry Baseline WERS maximum is 86 Indoor Water Savings 35% 65 WERS

10. About Hot Water Waste 1.5 gallons of water wasted to get Hot Water to fixture used as baseline. If you beat the base line with a non recirculation system you will lower your WERS Index But If you have a recirculation System it must be “On Demand” to get points for this practice.

11. IAQ Tight Homes need proper ventilation Whole building ventilation is Mandatory if the home has 5 ACH 50 or less. Bathroom fans to be vented and tested for 50 cfm intermittent or 20 cfm continuous Mandatory. Radon Mitigation still Mandatory in Zone 1. A short list of Builder Verified indoor materials with low or no VOC or other hazardous components.

12. Sustainable Practices Landscape components Infill lot better defined Wildlife habitat Owner’s manual (1/2 of the material supplied by BGNM) Builder provides location of all shutoffs and Maintenance Requirements to get the most of their green home Durability Practices Use of recycled content, Certified wood products and engineered products are given point value. Universal Design practices Home Size matters…

13. Home Size Matters Larger homes lose points based on # of bedrooms Smaller homes Gain points based on # of Bedrooms 1 extra point is required for each 300 sq. ft. or fraction there of over benchmark home size. (enter as a negative) Not intended as social engineering but to bring energy and other use (footprint) of home nearer to the average # of Bedrooms12345 Size of Home10001600220028003400

14. Mandatory Practices Energy 9 Water 1 IAQ11 Sustainability 4 Total25

15. Threshold for different levels Bronze HERS 65 or lower and meet all mandatory practices. No Extra points required Silver Energy; HERS Index of 58 Water;WERS Index of 80 or lower Additional Points in any category Gold Energy; HERS Index based on Climate Zone 51 to 55 Water;WERS 75 or lower Additional Points in any category

16. … and for Emerald Think “Show Home” Indoors and out 1.Renewable Energy production to lower HERS Index 20% below Gold Level 2.Water Catchment or reuse storage of at least XXX Gallons 3.Landscape to showcase appropriate Xeric planting and irrigation even if not fully completed and evidence that turf is < 10% of landscape area. 4.Additional points in any category
