Why Rating is important

• Policies Regulations Are difficult to implement
  and enforce unless one has the infrastructure to
  support compliance (ratings, certification,
  product testing, quality control, whole building
  integrated performance)

• Helps to verify code compliance
• Provides product performance comparison and
  assists consumer to make informed decision
• Promotes energy efficiency by providing a base
  line for product development and improvement.
  Also creates market competition for improved
  products
• Consumer benefit (assured payback, Insurance, tax
  incentives, and etc.

Requirements of a Successful Rating System

• Fair, accurate and unbiased
• Based on Science
• Provide Verifiable, Repeatable and Consistent
  Results
• Evaluation Based on Fixed Conditions
• Cost Effective for Adoption
• Industry buy-in

8
Structure Of A Rating Organization
Governance Body Board of Directors which is
balanced between Industry and Consumer interest
representation
Membership Participates in the program and pays
fees
Committee responsible for development of
procedures and standards
Executive office and Staff Carries out day to
day operation and management
Testing and Simulation Laboratories accredited by
the Governing Body Service Provides Energy
ratings per prescribed standards
Inspection Agency Licensed by the Governing
Body Service Audits products which the
participants rate.

Applicable ISO Standards

• ISO 15099 -Thermal Performance of Windows,
  Doors and Shading Devices  Detailed Calculations
  
• ISO 12567 Thermal performance of windows and
  doors -Determination of thermal transmittance by
  hot box method
• Part 1 Complete windows and doors and
• Part II Roof windows and other projecting
  windows
• ISO 9050 - Glass in building-Determination of
  light transmittance, solar direct transmittance,
  total solar energy transmittance, ultraviolet
  transmittance and related glazing factors

Rating of Products Pre Fabricated

• Temporary (Displayed for Verification removed
  after installation and inspection)
• Permanent (Part of the window, used for
  replacement of components to preserve performance)

Implementation of Successful Rating System

• Referenced by Codes and Regulations
• Promotional Programs like Energy Star
• Financial Incentives

19
Fenestration Code

• IECC IBC International (Energy Conservation
  Code International Building Code)
• IECC and IBCs Energy Code require rating for
  Residential and Non-Residential and specify NFRC
  certification for compliance.
• ASHRAE (American Society of Heating,
  Refrigeration Air Conditioning Engineers)
• ASHRAE 90.1 Energy Standard for Buildings Except
  Low-Rise Residential Buildings require U-factor
  and Solar Heat Gain and specify NFRC
  certification for compliance.
• ASHRAE (American Society of Heating,
  Refrigeration Air Conditioning Engineers)
• ASHRAE 90.2 Energy Standard for Low-Rise
  Residential Buildings require U-factor and Solar
  Heat Gain and specify NFRC certification for
  compliance.

Tax Credit

• the IRS has provided a special rule (on page 7
  of the IRS notice 2006-26) for claiming the
  residential tax credits with Energy Star windows
• .03 Special Rule for Energy Star Windows and
  Skylights. A taxpayer may treat an exterior
  window or skylight that bears an Energy Star
  label and is installed in the region identified
  on the label as an Eligible Building Envelope
  Component and may rely on such Energy Star label,
  rather than on a manufacturers certification
   statement, in claiming the 25C credit.

23
Impact Rating Can Have in The Market Place
The impact of successful NFRC rating program, in
the year 2003 in the USA, 41 of all conventional
residential windows were energy rated and were
classified as Energy Star Windows which would
not have been possible without NFRC ratings. As
a result, NFRC was active in saving over 7
billion BTUs (and 2 million kWs peak load) in
just one year (2003).
