What Medlock is, and isn’t

MEDLOCK IS NOT

Overview of LEED

An Architectural Award Winner

The Perfect Green Home

MEDLOCK ISThe first LEED certified single-family remodel in Arizona

The second LEED Gold certified single-family remodel in the U.S.

• A good case study for green remodeling

• Well Planned Remodel

• A project that preserved all exterior walls

• An improvement to traditional building code and practice

MEDLOCK IS

1 = 1 pt - High albedo materials installed for at least 50% of the site’s hardscape

POINT SYSTEM

Inspiration, asu, etc

Conclusions: Remodel existing home, in the urban core & make it green. What is green? Need a rating system.

So, the LEED education begins…..

1. Share the LEED for Homes Experience – 2007 – A GREEN REMODEL EDUCATION

2. Lessons learned, the need for a Rating System, Green by Definition, Material Selection, Recycling, The Cost, A LEED Case Study

3. Tax Credits, Rebates, and Stimulus Funds4. Explain the NAHB Green Rating System5. Putting the NAHB Green Rating System to Practice6. TOP 10 List – low budget or open budget7. Q & A: Expert Panel

WORKSHOP OVERVIEW

1. Test ducts for tightness, and sealing of leaks.2. Professional HVAC service, and install of programmable thermostat3. Caulking of and leaks in the building envelope, including windows and doors4. The use of a recycle bin in the kitchen.5. Replacement of incandescent lighting with cfl’s6. The use of household cleaners that do not contain toxic chemicals.

Homemade cleaners are best, using items such as vinegar, baking soda, and tea tree oil. And, the elimination of all chemical air fresheners.

7. The use of shading via plants or screens on walls or windows with high sun exposure.

8. The installation of daylighting in dark areas of your home to reduce the need for lights and to improve mental health

9. Upgrade insulation to a higher R value10. Installation of highly reflective window film

TOP TENLOW BUDGET GREEN HOME IMPROVEMENTS:

1. Foam insulation in the lid of the roof2. New windows3. New HVAC (always windows before HVAC, and Manual J required before

determining size of unit)4. Solar Hot water heater (current incentives and rebates results in a $1500 net

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

Why Build Green?

IN SIMPLE TERMS:

GREEN = REDUCING

ENVIRONMENTAL IMPACT

Conventional Building Processvs

Integrative Design Process

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.

GSA Requires all building projects starting design in 2003 meet LEED certified level standards with a target of LEED Silver.

Arizona Currently requiring LEED Silver on all state-funded buildings and requires incorporation of renewable energy.

California Executive Order #S-20-04 requires all new and renovated state-owned facilities to be LEED Silver

Los Angeles Requires LEED Certification of all public works construction projects over 7,500 gsf.

Georgia Tech requires LEED Gold for all new buildings and renovations

ASU all new buildings must be LEED

In the District, every new or substantially renovated nonresidential privately owned building with at least 50,000 square feet of gross floor area must submit a green building checklist with its application for a building permit. Beginning Jan. 1, 2012, every new nonresidential building, regardless of size, must be LEED certified.

In Montgomery County, every new or extensively modified commercial or multifamily residential building with at least 10,000 square feet of gross floor area must be LEED certified.

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%
