cost to homeowner)5. Front loading clothes washer, will reduce water usage by more than 60%
compared to a top loading washers)6. Native landscaping along with an irrigation system, and turf reduction7. Consideration of low environmental impact materials when selecting new
cabinets, flooring, countertops, or paint.8. A rain capture system, and consideration to low flush toilets and Water Sense
labeled fixtures9. A Photovoltaic system once doing all the above building envelope
improvements, which will reduce the size of the PV system needed10. Get your project LEED or NAHB certified
TOP TENMEDIUM TO HIGH BUDGET GREEN HOME IMPROVEMENTS:
1. Share the LEED for Homes Experience – 2007 – THE START OF A LEED EDUCATION
2. CASE STUDY: Describe the LEED process, including lessons learned, rating system comparisons, green by LEED definition, trade-offs of material selection, recycling, the project costs, energy analysis, and tax benefits.
3. Explain the NAHB Green Rating System and the utilization of it. And, the Top 10 lists
4. LEED GA PREP: Define LEED and the USGBC and share the overview of the rating system

TODAY’S OVERVIEW
To be eligible for the LEED Green Associate credential, you must have previous experience supporting a project registered for LEED certification, working in a sustainable field of work, or attending an education program that addresses green building principles. Only one of these criteria is required to be met to demonstrate eligibility.
The LEED Green Associate exam is a 2-hour exam. The LEED Green Associate exam is neither a prerequisite nor an eligibility requirement for the LEED AP or any other GBCI exam.
To be eligible for the LEED AP credential, you must have previous experience with a project registered for LEED certification within three years of your application submittal date. This work experience must be documented in the form of a letter of attestation from a supervisor, client, or project manager and must describe your involvement on the LEED Project as a consultant, contracted worker, member of the LEED project team, LEED Homes Provider, LEED Reviewer, LEED for Homes Green Rater, or staff member of a Certifying Body (CB).
The LEED AP is a 4-hour exam comprised of two parts: the LEED Green Associate and LEED AP specialty exams. (If you are enrolling or currently hold an active LEED Green Associate or LEED AP credential, you are exempt from the first part.) If you wish to take the exam in two 2-hour sessions, you may first apply for and earn the LEED Green Associate and then apply for the LEED AP including demonstrating eligibility and paying the applicable fees.

Green Building: Washington Bill Requires LEED Certification For Sales and Use Tax Deferral A bill was introduced in the Washington State Legislature yesterday that will require LEED certification for sales and use tax deferral on select construction projects. If this bill (SB 6598) becomes law, projects will have to achieve a certain level of LEED certification to qualify for deferral of sales and use tax on materials and other components of the work. The higher the project's LEED certification, the greater the amount of sales and use tax that's deferred. This chart identifies the percentage of sales and use tax each level of certification will deliver:
LEED Certification Level
Percentage of Sales and Use Tax Deferred
Platinum 100%
Gold 75%
Silver 50%
Less Than Silver 25%
