Energy Efficiency & Thermal Performance

ENERGY STAR® Ratings & Performance Criteria


Make Your Home More Energy Efficient

An energy efficient home doesn't have to compromise beauty or natural light. Blink® Blinds + Glass products by ODL can be used in exterior doors and windows to meet ENERGY STAR® specifications, and increase the energy efficiency of your home. ODL is an ENERGY STAR® stakeholder.

When installed in the proper door or window, select Blink Blinds + Glass products meet regional ENERGY STAR® thermal performance standards as defined by the U.S. Department of Energy (DOE) and Natural Resources-Canada (NR-Can). Local and state codes are developed using ENERGY STAR® guidelines but may be more or less stringent.

Energy Efficiency Properties of Doors and Windows

The thermal performance of doors and windows is measured by two properties: resistance to heat flow and resistance to sunlight warmth.

  • Heat flow is expressed by the U-factor value; less heat flow yields a lower U-factor value.
  • Resistance to sunlight warmth is measured by the Solar Heat Gain Coefficient (SHGC); less sunlight warmth through the window yields a lower SHGC.

Blink Blinds + Glass Ratings

Energy efficiency ratings for Blink Blinds + Glass products by ODL vary by door and window construction, size of the unit, and door and window materials.

The ratings of participating entry door manufacturers can be found in the Thermal Performance Database. Contact us for more information about which entry door and doorglass combinations meet ENERGY STAR® requirements. Ratings for windows are not available at this time.

U.S. ENERGY STAR® Criteria for Doors

(Effective January 1, 2015)

The U.S. standards include criteria for air leakage. Swinging doors cannot exceed 0.5 cfm/ft2.

Glazing Level U-Factor SHGC
Opaque < or = 0.17 No criteria
< or = 1/2 Doorlight < or = 0.25 < or = 0.25
> or = 1/2 Doorlight < or = 0.30 < or = 0.40 for Northern and North-Central Zones
< or = 0.25 for Southern and South-Central Zones

U.S. ENERGY STAR® Criteria for Windows

(Effective January 1, 2015)

Climate Zone U-Factor SHGC
Northern < or = 0.27 Any Prescriptive
= 0.28 > or = 0.32 Equivalent Energy Performance
= 0.29 > or = 0.37
= 0.30 > or = 0.42
North Central < or = 0.30 < or = 0.40
South Central < or = 0.30 < or = 0.25
Southern < or = 0.40 < or = 0.25

Canadian ENERGY STAR® U-Factor and Energy Rating Criteria for Windows and Swinging Doors

(Effective February 1, 2015)

Canadian standards are the same for opaque and glazed doors.

Canadian standards include a criteria for air leakage: leakage cannot exceed 1.5 L/s/m2, or 0.3 cfm/ft2.

Maximum U-Factor Minimum Energy Rating
Metric Units Imperial Units
Zone 3 1.20 0.21 34
Zone 2 1.40 0.25 29
Zone 1 1.60 0.28 25

The 2015 Canadian climate zones are determined by heating degree day (HDD) values as found in the Model National Building Code (2010).

Zone 3: > or = 6000 HDDs
Zone 2: 3500 to < 6000 HDDs
Zone 1: < 3500 HDDs
