Energy Efficiency and Sustainability

Products that are good for our partners and our planet.

We promote sustainability initiatives throughout Western Window Systems and strive to develop luxury door systems and windows that are as energy efficient as possible. Our signature designs allow for more glass, light, and fresh air while still providing energy savings and long-term performance. When we manufacture our products, we utilize materials and resources as effectively as we can. And because we build our products to last, they stay out of landfills longer.

Best of all, because our products are completely customizable, you can select or combine options that meet your project’s performance requirements.

Energy Efficiency and Sustainability
"The efficiency and airflow in regard to the heat and the cold is amazing. We didn't turn on our heat once last winter." Sharon Newman, homeowner

Energy Efficiency

Insulating Glass

All our products feature dual-paned, triple-coated low-E glass, meaning they block a substantial amount of heat transfer, helping to reduce heating and cooling costs.

Weatherstripping

Our door systems feature tight, durable seals that help control humidity and moisture and minimize air leakage.

Thermally Broken Aluminum

Many Western Window Systems doors and windows are available with the option of thermally broken aluminum, which features an insulating barrier that increases energy performance.

Designed and Tested

Every Western Window Systems product is subjected to air, water, and structural testing and is tested and certified by the NFRC (National Fenestration Rating Council) and AAMA (American Architectural Manufacturers Association).

What is Title 24

Take the guesswork out of California's energy code.

Title 24 part 6 of the California Code of Regulations addresses energy efficiency in residential and non-residential buildings. Created in 1978 by the California Building Standards Commission, the purpose of Title 24, also known as the California Energy Code, is to reduce California’s energy consumption.

Because energy efficiency reduces energy costs to homeowners and impacts on the environment, building standards are an important part of California’s future. Before a city or county in California will grant a building permit, the newest energy code requires the submission of a Title 24 energy report (also called Title 24 energy calculations) to verify that the design of a building is in compliance with Title 24.

The good news is that California’s Title 24 goal of reducing home energy consumption can be achieved without sacrificing a home’s design or settling for undesired products. And for architects, dealers, and homeowners in California who insist on the proven performance and clean aesthetic of products from Western Window Systems, the solution is two words: Performance Method.

"We have six 12-foot-wide by 6-foot-tall panel windows that are thermally sound and very energy efficient." Dean Papadopolous, homeowner

The Performance Method Advantage

  Prescriptive Performance
Flexibility    
Accuracy    
Design friendly    
May save on construction costs    
More trade-offs    
Recommended for new homes/large additions    
Requires special software/consultant    
Simplicity    
Limits number of windows and doors    
Limits west-facing glass    

The Performance Method Advantage

There are two methods of compliance for Title 24: Prescriptive and Performance. Both reports require information pertaining to the energy efficiency and construction of the home, but the Performance Method offers several distinct advantages.

The Prescriptive Method

This method may be the simplest approach to Title 24 compliance, but it’s also the least flexible and requires each individual component to meet the prescribed minimum energy requirement. This may result in sacrifices to architectural design, over-insulating or installing potentially expensive energy upgrades, and higher construction costs.

The Performance Method

The Performance Method requires more effort to achieve compliance but provides the greatest amount of flexibility, is the most accurate, and may save considerably on construction costs. The minimum level of energy efficiency necessary for compliance is calculated through a specialized state-approved software program using a detailed account of the building. The flexibility of the Performance Method allows for more trade-offs, fewer limits on glass, and is recommended for new homes or large additions.

A consultant can prepare certified Title 24 energy calculations and compliance reports. Costs will vary depending upon the square footage.

Three Easy Compliance Ideas

1.) Find out the compliance method being used on the project. Most new homes, custom homes, and large additions will utilize the Performance Method.

2.) Quote the project using Western Window Systems products and work with an energy consultant in your area. Costs will vary depending upon the square footage.
