Energy Efficiency



ENERGY STAR is the trusted, government-backed symbol for energy efficiency helping us all save money and protect the environment through energy-efficient products and practices.

The ENERGY STAR label was established to:

 


• Reduce greenhouse gas emissions and other pollutants caused by the inefficient use of energy.

• Make it easy for consumers to identify and purchase energy-efficient products that offer savings on energy bills without sacrificing performance, features, and comfort.


How Does EPA Choose Which Products Earn the Label?

Products can earn the ENERGY STAR label by meeting the energy efficiency requirements set forth in ENERGY STAR product specifications. EPA establishes these specifications based on the following set of key guiding principles:
 

• Product categories must contribute significant energy savings nationwide.

• Qualified products must deliver the features and performance demanded by consumers,
  in addition to increased energy efficiency.

• If the qualified product costs more than a conventional, less-efficient counterpart,
  purchasers will recover their investment in increased energy efficiency through
  utility bill savings, within a reasonable period of time.

• Energy efficiency can be achieved through broadly available, non-proprietary
  technologies offered by more than one manufacturer.

• Product energy consumption and performance can be measured and verified with testing.
 
• Labeling would effectively differentiate products and be visible for purchasers.



How Does EPA Decide When to Revise Specifications?


Generally, a market share of ENERGY STAR qualified products in a particular category of 50 percent or higher will prompt consideration for a specification revision. However, there are other factors that weigh into the decision, such as:

• A change in the Federal minimum efficiency standards.

• Technological changes with advances in energy efficiency which allow a revised ENERGY STAR specification to capture additional savings.

• Product availability

• Significant issues with consumers realizing expected energy savings

• Performance or quality issues

• Issues with Test Procedures

 

Northeast Building Products offers two optional Camelot® Performance Packages which feature the latest and most innovative energy efficiency technologies. From Sashlite’s® revolutionary integrated spacer to energy-saving Low-E pyrolytic hard-coat glass options, Camelot® Performance Package windows will help reduce home-heating and cooling costs...while providing you and your family with year-round comfort, dependability and style. Below we provide a brief overview of how environmental factors influence window performance:

CNN Interviews CEO Alan Levin of Northeast Building Products
1 CONVECTION

Warm inside air meets a cold window, creating a chilly, circulatory. Performance Package windows can help reduce convection related problems.


2 AIR INFILTRATION

Air leakage through unsealed gaps can account for up to 10% of the energy usage in a home. Performance Package windows offer premium airflow protection.



3 RADIANT HEAT LOSS   

Clear glass absorbs interior heat and radiates it outdoors. Low-E glass coatings greatly reduce radiant heat loss, saving you money in the winter.

4 CONDUCTION

The direct transfer of heat through the window frame. Performance Package windows reduce thermal heat loss due to conduction.


5 SOLAR RADIATION

In the summer months, solar radiation can dramatically increase home cooling costs. In addition, UV radiation can fade and damage interior furnishings. Performance Package windows feature a Low-E micro-coating which greatly reduces solar radiation and provides superior UV protection.


6 LIGHT TRANSMITTANCE

Low-E coatings allow short wave visible light to be absorbed through the window, which reduces lighting costs throughout the year and is reradiated as heat in the winter.


7 CONDENSATION

Condensation can damage window frames, sills, and interior shades while contributing to mold and indoor humidity. Northeast offers warm-edge spacers for superior condensation resistance.


Thermal Transmittance and Resistance (U and R-Values)

    

Thermal transmittance, also known as U-value, is the rate of heat transfer between the interior and exterior of a window. The R-value of a window, also known as “thermal resistance”, is simply the reciprocal of the U-value (1/U). So if a window has a U-Value of 0.20, it will have an R-Value of 5 (1/0.20).

The higher the R-value of a window, the greater its insulating properties, and thus the greater its energy efficiency. Camelot® R-5 Ultra Performance Package windows feature one of the highest double=glazed R-values in the industry, for the ultimate in energy-efficiency and thermal performance.
 

 

PERFORMANCE

 

R5 ULTRA PERFORMANCE PACKAGE
Northeast’s R5 Ultra Performance Package option, exclusive to the Crusader® Series, delivers windows with an R-Value of 5 (U-Factor of 0.2) and features:

1 SOFT-COAT LOW-E PANE   
Microscopic layers of silver and titanium dioxide are applied to  Surface 2 of low-emissivity glass, rated PPG Solerban 60. This blocks 62% of solar energy while allowing 70% of visible light through).

2 ARGON GAS
Clear, non-toxic Argon gas fills the insulated glass unit to reduce the thermal conductivity of the airspace between the glass layers for increased energy efficiency.

3 FOAM ENHANCEMENT   
The hollows inside the vinyl master frame and sash are injected with polyurethane foam to reduce thermal conductivity and help your windows operate at peak thermal efficiency year round.

4 LOW-E PYROLYTIC HARD-COAT PANE
A transparent, molecularly bonded silicon-oxy-carbide ceramic coating on Surface 4 reflects long wavelength infrared energy.
