LEED Certification

Energy & Atmosphere

According to Architecture 2030, three-fourths of all electrical energy in the U.S. is used to operate buildings. Reducing energy use in buildings through improved energy performance and energy-saving strategies like daylighting helps reduce the impact buildings have on our atmosphere.

How glass block can help:

Prerequisite 2: Minimum Energy Performance
Glass block’s daylighting properties can help achieve the required minimum energyperformance for LEED® certification.

Credit 1: Optimize Energy Performance
Glass block can support various strategies, including passive solar designs, to reduce a given building’s energy consumption. And because this credit includes interior lighting energy demands, glass block can improve energy performance even more.

Recent developments in glass block have significantly improved thermal performance. Pittsburgh Corning’s Energy Efficient Glass Block demonstrates up to a 43% improvement in U value and up to a 52% improvement in Solar Heat Gain Coefficient when compared to the baseline performance ratings for glass block specified in ASHRAE/IESNA 90.1-2007.

Materials & Resources

The production and transport of building materials can impact our environment in many ways. Conserving resources, using local materials and reducing construction waste reduces that impact.

How glass block can help:

Credits 2.1 and 2.2: Construction Waste Management
Both glass block scrap and its packaging can be recycled, nearly eliminating waste.

Credits 3.1 and 3.2: Resource Reuse
Salvaged glass block can be reused in some jurisdictions with careful consideration.

Credits 5.1 and 5.2: Regional Materials
Glass block manufactured in a facility within 500 miles of a project site can include that percent (by weight) of the raw materials that are also within 500 miles of the project site toward the calculation of the total regionally located content in all building materials.

With Pittsburgh Corning’s glass block manufacturing facility in Port Allegany, PA, architects can achieve credits for projects in several major metropolitan areas, such as Chicago, New York, Philadelphia, Washington D.C., Charlotte, Cleveland, Indianapolis, Columbus.

Indoor Environmental Quality

The U.S. EPA estimates that the average American spends over 80 percent of his/her time indoors. It is important for our own wellbeing to create indoor spaces that are healthy and comfortable.

How glass block can help:

Credit 4: Low Emitting Materials
Glass block meets the intent of eliminating VOCs from the indoor environment when used as interior walls or floors.

Credit 8: Daylight and Views
Glass block provides daylight and views without sacrificing sound control, security and privacy.

Suggested Applications: The Solar Wall Tube by Pittsburgh Corning offers a unique and creative way to maximize natural light entering the building.

Innovation & Design

The LEED® Rating System, while comprehensive, is not complete. Other aspects of sustainable design, not covered in LEED®, are also important. These can be recognized in the Innovation in Design credit. Suggested Applications: New LightWise® Architectural Systems from Pittsburgh Corning offer all of the benefits of glass blocks in easy-to-install windows and panels and can provide additional resistance to hurricane, blast, intruder or ballistic threats.

How glass block can help:

Credit 1 – up to three points
Glass block can help earn points for good acoustics, use of durable materials, and good indoor environmental quality (no VOC, no mold).

Regional Bonus Credits
Pittsburgh Corning will be happy to help you with glass block solutions that can be used to help fulfill specific regional credits. For example, the new LightWise® Architectural Hurricane Resistant window has been tested to the high-wind and large missile impact requirements of Dade County Florida.

It is important to recognize the value of a holistic approach to sustainable design, and to weigh social and economic considerations as well as environmental ones. Pittsburgh Corning is committed to helping architects and building planners design and construct projects that are both inspired and sustainable.
