  3. What is Build Green NM • Operates under the Foundation for Living (Formerly Foundation for Building) a 501 c 3 non profit • Provides 3rd 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 Level HERS 65 • Silver Level HERS 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

  9. 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. (Push button or motion sensor) • Timer No Points • Constant on No Points • Aquastat No Points • “Smart” controller No Points

  10. 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.

  11. 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…

  12. 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

  13. Mandatory Practices • Energy 9 • Water 1 • IAQ 11 • Sustainability 4 Total 25

  14. 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

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