5.8.2 Fenestration and Doors

5.8.2.2 Labeling of fenestration Products. All manufactured fenestration products shall have a permanent nameplate, installed by the manufacturer, listing the U-factor, SHGC, and air leakage rate. 2010 also requires “Visible Transmittance (VT)”

Exception: When the fenestration product does not have a nameplate, the installer or supplier of such fenestration shall provided a signed and dated certification for the installed fenestration listing the U-factor, SHGC, and the air leakage rate.

303.1.3 Fenestration product rating. U-factors of fenestration products (windows, doors and Skylights) shall be determined in accordance with NFRC 100 by an accredited, independent laboratory, and labeled and certified by the manufacturer. Products lacking such a labeled U-factor shall be assigned a default U-factor from Table 303.1.3(1) or 303.1.3(2). The solar heat gain coefficient (SHGC) of the glazed fenestration products (windows, glazed doors and skylights) shall be determined in accordance with NFRC 200 by an accredited, independent laboratory, and labeled and certified by the manufacturer. Products lacking such a labeled SHGC shall be assigned a default SHGC from table 303.1.3(3).

2009 IECC

2006 & 2009 IECC - Require Air Leakage labeling, but site –constructed windows and doors do not require labels. Curtain Wall and Storefront can be handled with ASTM E 283 Test Reports

AAMA 507

PurposeA standard method for determining the thermal performance of building specific fenestration systems – The specific elevation

Thermal Characteristics to be discussed:

Scope

Standard Practice for Determining the Thermal Performance Characteristics of Fenestration Systems Installed in Commercial Buildings

How do we pre-qualify thermal performance of a fenestration system?

U-Factor: Rate of heat loss. The lower the U-factor the better the fenestration’s resistance to heat flow.

U-Factor is denoted as BTU/hr.ft2.oF (W/m2.oC)U-factor is the inverse of R-Value

From our previous example: 1 / 0.46 = 2.2 R-value

Solar Heat Gain Coefficient (SHGC): Ratio of the solar heat gain entering the space through the fenestration product to the incident solar radiation. The lower the SHGC, the less solar heat it transmits, and the greater its shading ability.

SHGC is denoted as a value between 0 and 1 without units.

Visible Transmittance (VT): Optical property that indicates the amount of visible light transmitted. The higher the VT the better the quality of daylight allowed thru the fenestration system. Note: The framing blocks all daylight.

VT is denoted as a value between 0 and 1, but most VT values fall between 0.30 and 0.80.

Defining the thermal characteristics of fenestration systems

Air Leakage (AL): Rate of air infiltration thru a fenestration system. Energy efficiency is lost as air passes thru a fenestration system therefore the lower the AL value the better. Choose systems with a 0.30 cfm/ft2 or preferably better.

AL is denoted as cubic feet per minute per square feet of opening - cfm/ft2

Condensation Resistance Factor (CRF): Is a ratio of the difference between an average inside surface temperature and the outside air temperature, and the difference between the inside air temperature and the outside air temperature. The higher the CRF, the higher the resistance to condensation.

CRF is denoted as a dimensionless rating number between 0 and 100 obtained under standard test conditions as prescribed in AAMA 1503 .

Referenced in AAMA 507 although it does not effect energy use, but is still an important thermal performance characteristic

CRF (g) = CRF Glass

CRF (f) = CRF Frame

TI = Warm Side Air Temperature

TII = Cold Side Air Temperature

CRF Prediction Formulas

CRF (g) = X 100gT – TII

TI - TII

CRF (f) = X 100fT – TII

TI - TII

gT = Glass Temperature Warm Side

fT = Frame Temperature Warm Side

Incorporating the proper Sunshades strategy can save 15%

Utilizing Light Shelves can save 25% (Based on 50% reduction in day time lighting)

Thermal Framing and LowE glass can save 13%

Integrating all these strategies could save 34% Plus

Achieve sustainable performance with aluminum commercial fenestration

Pre-Consumer

Post Consumer

Extracted, harvested or recovered

Recycled Content – Post Consumer

Aluminum Fenestration can contain Post Consumer recycled content, but due to quality issues with extrusions meeting tempering tolerances and finish post consumer

percentages are typically limited to 35%. Some manufacturers avoid post consumer recycled content because of these quality issues.

MR Credit 4

“Discarded materials fromone manufacturing processthat are used as constituentsin another manufacturingprocess are pre-consumerrecycled materials.”

AIA MASTERSPEC 2005

Recycled Content – Pre-Consumer (1/2)

Aluminum Fenestration can contain pre-consumer recycled content of 0% to 100% depending on the manufacturer and the requirements of the project

Recycled aluminum requires only 5 percent of the energy required to make "new" aluminum. Blending recycled metal with new metal allows considerable energy savings, as well as the efficient use of process heat. MR Credit 4

Regional Materials – Extracted

Aluminum is a by product of Bauxite mining and would not qualify due to the fact that there are no architectural grade aluminum Bauxite mines operating in the United States

Bauxite output in 2005 shown as a percentage of the top producer (Australia- 59,969,000 tonnes)

Indoor Environmental Quality – Increased Ventilation

Operable Windows can be used if the naturally ventilated option is explored.

This strategy can sometimes be used meeting the IEQ Credit 6.2 credit as well to eliminate or reduces HVAC energy demands in some climates.
