The performance data applies to insulating glass units with two plies (clear inboard) of 1/4" (6mm) glass and a 1/2" (13.2 mm) airspace

or argon space. The coating is applied to the second (#2) surface.

The solar and optical data presented in this guide is center-of-glass data based on the National Fenestration Rating Council

measurement standards. They were calculated using Lawrence Berkeley National Laboratory’s (LBNL) WINDOW 5.2/6.3 software.

In some cases performance data changed in comparison to previous versions of LBNL’s WINDOW program.

The performance data applies to insulating laminated glass constructed with three plies (clear inboard laminate) of 1/4" (6mm) glass,

a .060 (1.52mm) clear polyvinyl butyral (PVB) interlayer and a 1/2" (13.2 mm) airspace. The coating is applied to the second (#2)

surface.

The solar and optical data presented in this guide is center of glass data based on the National Fenestration Rating Council

The performance data applies to triple insulating glass units with three plies (clear lites unless otherwise specified) of 1/4"

(6mm) glass and two 1/2" (13.2mm) airspaces or argon spaces. The coating is applied to the second (#2) surface. If double coated,

a VE-85 coating is applied to the fourth (#4) surface.

The solar and optical data presented in this guide is center-of-glass data based on the National Fenestration Rating Council

ENERGY TERMS

Visible Light TransmittanceThe percentage of visible light (380 - 780 nm) that is transmitted

through the glass.

Solar TransmittanceThe percentage of ultraviolet, visible and near infrared energy (300 -

3000 nm) that is transmitted through the glass.

Visible Light ReflectanceThe percentage of light that is reflected from the glass surface(s).

Solar ReflectanceThe percentage of solar energy that is reflected from the glass surface(s).

NFRC U-ValueA measure of heat gain or heat loss through glass due to the differ-

ences between indoor and outdoor temperatures. These are center

pane values based on NFRC standard winter nighttime and summer

daytime conditions.

U-values are given in BTU/(hr*ft2*°F) for the English system. Metric

U-values are given in W/(m2*°K). To convert from English to metric,

multiply the English U-value by 5.6783.

NFRC winter nighttime U-values are based on an outdoor temperature

of 0°F (-17.8°C), an indoor temperature of 70°F (21°C) and a 12.3

mph (19.8 km/h) outdoor air velocity.

NFRC summer daytime U-values are based on an outdoor temperature

of 89°F (32°C), an indoor temperature of 75°F (24°C), a 6.2 mph

(10.1 km/h) outdoor air velocity and a solar intensity of 248

BTU/(hr*ft2*°F) (782 W/m2).

R-ValueThermal resistance is expressed in ft2*hr*°F/BTU. It is the reciprocal of

U-value. The higher the R-value, the less heat is transmitted through

the glazing material.

Shading CoefficientShading coefficient is the ratio of solar heat gain through a specific

type of glass that is relative to the solar heat gain through a 1/8"

(3 mm) ply of clear glass under identical conditions (see Figure 9).

As the shading coefficient number decreases, heat gain is reduced,

which means a better performing product.

Relative Heat Gain (RHG)The amount of heat gained through glass taking into consideration

U-value and shading coefficient. Using the NFRC standard, relative

heat gain is calculated as follows:

English System:

RHG = Summer U-value x 14°F + shading coefficient x 200.

Metric System:

RHG = Summer U-value x 7.8°C + shading coefficient x 630.

Solar Heat Gain Coefficient (SHGC)The portion of directly transmitted and absorbed solar energy that

enters into the building’s interior. The higher the SHGC, the higher

the heat gain.

Light to Solar Gain Ratio (LSG)The ratio is equal to the Visible Light Transmittance divided by the

Solar Heat Gain Coefficient. The Department of Energy’s Federal

Technology Alert publication of the Federal Energy Management

Program (FEMP) views an LSG of 1.25 or greater to be Green

Glazing/Spectrally Selective Glazing.

European U-Value (formerly K-Value)Based on ISO-DP10292 draft standard conditions. It is based on an

outdoor temperature of 5.5°C, an indoor temperature of 20.5°C

and a 4.8 m/s outdoor air velocity.

The solar and optical data presented in this guide is based on the National Fenestration RatingCouncil measurement standards. They were calculated using Lawrence Berkeley Laboratories (LBL)new WINDOW 5.2 software. In some cases performance data changed in comparison to previousversions of LBL’s WINDOW program.
