Industry Standard

What value is there in having an industry standard?

How can it be useful to building professionals??

�It sets criteria.

�It provides a resource/guideline.

�It provides a basis for building

Slide 9

�It provides a basis for building

incentive/rebate programs.

�It likely will overtake local programs and

provide more consistency.

�Especially since it is ANSI certified; it tends

to raise the bar on code over time.

Schedule a Verifier

� Points claimed must be verified

through at least two field inspections.

� Verifiers must:

� Be accredited by the NAHB Research Center

� Demonstrate experience in construction or




� Demonstrate experience in construction or

inspections, sustainable building practices and energy

conservation

� Complete a course and test

� Be an independent party

� Not work for HBA or supply products/services

� Not be trade contractors or suppliers for the

verified/certified homeSlide 18

Verifier Inspection Process

1. Create the Verification Report

Certification Process DiscussionWhere do you see builders having the most difficulty in the

certification process??

How can these challenges be addressed??

• Being Prepared for verification inspections.

• Having time for the process.

Slide 20

How can these challenges be addressed??

What advice could you offer to those who have not been through the

process??

• Talk to a HERS Rater or Verifier.

• Be prepared and have documentation on hand.

Green Remodeling and the

Standard

� Incorporating sustainable, durable, and healthy features in the renovation of existing homesexisting homes

�Energy efficient features

�Green deconstruction and recycling practices

� There is a huge market opportunity!
