Transforming Product Performance Efficient Energy Efficiency Policies

Why Rating is important

• 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.

• 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)

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

Structure Of A Rating OrganizationGovernance Body

Board of Directors which is balanced between Industry and Consumer interest representation

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.

Membership: Participates in the program and pays fees

Executive office and Staff: Carries out day to day operation and management

Committee responsible for development of procedures and standards

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

Testing Used for Windows, Product Certification

Fenestration:• Simulation of U-factor, Solar Heat Gain

Factor and Visible transmittance - ISO 15099

• U-factor testing - ASTM C 1363, C1199, NFRC 102

• Solar Heat Gain Testing – NFRC 201• Spectral Optical Property – ISO 9050,

ASTM E903, NFRC 300, 301• Air Leakage – ASTM E283, NFRC 400

Implementation of Successful Rating System

• Referenced by Codes and Regulations

• Promotional Programs like Energy Star

• Financial Incentives

Fenestration & Code

• IECC & IBC International (Energy Conservation Code & International Building Code)

– IECC and IBC’s 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.

Energy Policy Act 2005 & Energy Star Program

Incentive Program

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 manufacturer’s certification  statement, in claiming the § 25C credit.

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 BTU’s (and 2 million kW’s peak load) in just one year (2003).
