Energy Efficiency #1 Green Feature for Buyers

October 31, 2007 - A new survey conducted for the National Association of Home Builders (NAHB) confirms that a desire for greater energy efficiency drives consumers to choose a green-built home.

Green building is the home buyer’s best defense against soaring energy costs,” said NAHB President Brian Catalde, a Southern California home builder. “But it’s up to the nation’s home builders to make sure the cure is not more expensive than the problem itself. The NAHB National Green Building Program paves the way for authentic yet cost-effective green building,” he said

Blue to Green

Building a safe and stable home for every American was the goal

and there was a concern about how the building affected our water

so in the begining was the cleanwater act.

Over a generation, builders learned to build in alignment,

and the Stormwater compliance specialist served

as the link between construction labor and law

Until construction mud ran in the streets and streams

only upon a weather Act of God or BMP or stormwater program failure

Stewardship of the land became less mystery and more ministry.

During this generation mountains grew from plains,

Until LandFill caterpillars became the highest vehicles in the land.

Sustainability became the cry of the home buyer.

and the home builders knew they needed to design

Developments new ways, homes new ways, place homes on lots in new ways,

and build in new ways.

The builders turned to the stormwater compliance specialists, because they were trusted.

And stormwater then became subset, a part of green building services the complaince specialist provided.

and every house became a sustainable house, where air, land, water and energy in construction was a consideration, and

Stewardship of the land became less mystery and more ministry

And building a safe and stable home for every American was better than ever.

LEED 201 the LEED Accredited Professional (LAP) Program

LEED Professional Accreditation provides verification of individual expertise in the principles of green building design, construction, and operation.

The credential helps building professionals establish credibility in the marketplace. In addition, LEED Accredited Professionals help building owners achieve performance goals and facilitate the LEED Certification process.

LEED APs are a critical link between LEED standards and professional practice.

There are no prerequisites for taking the LEED Professional Accreditation exam, however, the following are recommended:

  • Building industry knowledge and tenure in green building
  • Familiarity with the documentation process for LEED certified projects
  • Knowledge of LEED credit intents, requirements, submittals, technologies, and strategies within your discipline
  • Practical experience working with multiple design disciplines
  • Understanding of life cycle costs and benefits of LEED
  • Familiarity with LEED resources and processes

The LEED Professional Accreditation program offers three exam tracks toward achieving the LEED AP credential. Passing any one exam track will earn the LEED AP designation.

Download the LEED AP Candidate Handbook for complete information on the accreditation process.

LEED for New Construction Exam Track

  • The LEED for new Construction exam track tests the candidate's knowledge of the LEED for New Commercial Construction and Major Renovations Rating System v2.2 and its application in practice.
  • The LEED for New Construction exam track provides a standard for professionals participating in the design and construction phases of high performance, healthful, durable, affordable, and environmentally sound commercial, institutional, and high-rise residential buildings.

Thursday, December 6, 2007

The LEED Rating System: An Introduction
LEED® certification is based on a point system.The amount of points achieved will determine which level of LEED® certification the project is awarded. There are 69 possible points and four certification levels.
  • Basic LEED® Certification requires 26 to 32 points;
  • LEED® Certified Silver Level requires 33 to 38 points;
  • LEED® Certified Gold Level requires 39 to 51 points; and
  • LEED® Certified Platinum Level requires 52 to 69 points.

USGBC organizes the available points for LEED® certification into six broad categories. Below is a list of the categories and examples of required and possible points for each of the categories.
USGBC also provides an optional sixth category for innovation and design process.

  • Using a LEED® Accredited Professional (LAP) (1 point).
  • Sustainable Sites (14 possible points total):
  • Erosion and Sedimentation Control (required point);
    Site Selection (1 point);
  • Urban Redevelopment (1 point); etc.
    Water Efficiency (5 possible points total):
  • Water Efficient Landscaping, Reduce by 50% (1 point);
  • Innovative Wastewater Technologies (1 point);
  • Water Use Reduction, 20% Reduction (1 point); etc.
  • Energy and Atmosphere (17 possible points total):
  • Fundamental Building Systems Commissioning (required point);
  • Minimum Energy Performance (required point);
  • CFC Reduction in HVAC&R Equipment (required point); Renewable Energy, 20% (1 point); etc.
  • Materials and Resources (13 possible points total):
  • Storage and Collection of Recyclables (required point);
  • Building Reuse, Maintain 75% of Existing Shell (1 point);
  • Construction Waste Management, Divert 50% (1 point); etc.
