Green Building Guru: Jason Kliwinski, Green Building Center

At the Green Builder Center exhibit (#2311), the concept of resilient design was top of mind. A recently published white paper by Jason Kliwinski, LEED Fellow, sheds important light on how “resiliency” plays a role in sustainable design. Specifically, Kliwinski says that to achieve resilient design, you must:

Plan ahead and expect the worst essentially. Thinking about how you will heat and cool your building without grid power, integrating storm water management strategies on your property and in your community to handle storm surges and to protect your property and lives, considering alternative means of transportation if you have to navigate closed or damaged roads or channel get fuel…

Are these considerations already apart of your planning process? If not, check out the full white paper at www.greenlivingandbuildingcenter.com.

Opening the Door to Better Classroom Acoustics

Slatington Elementary ClassroomLast year, I was presented with a unique opportunity to apply our building science research into a real-life application — the renovation of an elementary school in northeastern Pennsylvania. Originally built in 1973, the school was transformed from an open concept interior space into individual state-of-the-art classrooms. Superior acoustical comfort, which can contribute to improved student performance and teacher retention, was a top priority in this field study as well as an analysis of the overall indoor environment that included air quality, thermal comfort and visual comfort measurements.

Our goal was to investigate the impact of installing different, high-performing interior acoustical ceiling and gypsum wallboard system solutions in six new classrooms constructed in the third grade student wing. Acoustical tests were conducted in each classroom to determine sound absorption and interior partition sound transmission levels, as well as major sound flanking paths.

As a leading manufacturer of ceilings and wall products, our team is well versed in the myriad of product specifications and configurations for our products. However, during the testing, I had an a-ha moment of sorts regarding the doorways to the classrooms.

Specifically, I realized that even though it is well known that acoustically isolated, airtight door assemblies improve classroom acoustics when used in conjunction with high-performance gypsum board and ceiling products, these elements are often specified independently rather than a comprehensive acoustical system. This is a challenge that I have always been aware of, but seeing it so clearly in this study led us to ask: what could we do about it?

Our curiosity led us to ASSA ABLOY, the global leader in door opening solutions. Through our alliance, we’ve uncovered easily accessible solutions found in door and frame systems, to address acoustical challenges and reduce the sound reverberation that further complicates noise issues in classrooms.

We look forward to sharing more detailed findings during Greenbuild 2013 through a dedicated education session at the Saint-Gobain Learning Lab. Please join us at the session or leave us a comment below to continue the discussion.

Fraunhofer Institute CSE To Showcase Contemporary Sustainable Building Technologies in Real-Life Installations for Building and Design Pros

With the constant flow of new products being developed these days for the sustainable building market, it can be easy to feel like using a new product for the first time is taking a big risk. Sometimes, all you have to go on are the presentation from your manufacturer rep, the manufacturer’s reputation and, if you’re lucky, an endorsement from an industry peer who had positive results with the product. It’s not often that architects and contractors get to a see a new product they’re considering installed in a real-life application before making their final decision. The Fraunhofer Center for Sustainable Energy Systems (CSE) hopes to help change that in the very near future.

The Fraunhofer CSE is currently remodeling a 100-year-old, 50,000 square-foot warehouse in Boston to be its new headquarters, as well as an important educational outlet for building and design professionals. The retrofitted building will serve as a living laboratory for building product research and demonstration, featuring a wide range of contemporary sustainable building technologies, such as CertainTeed’s AirRenew® M2Tech® IAQ Gypsum Board.

Fraunhofer CSE will evaluate the overall performance of the products after they are incorporated into the building’s various systems and assemblies to help manufacturers give their products a true test run with building-integrated and other applied research methods. The organization also plans to showcase these products in an open-to-the-public exhibition and educational space, using innovative applications, such as smart phone and tablet apps, to call attention to energy saving and/or sustainable construction attributes. This invaluable, unprecedented service will allow everyone, from veteran architects and construction pros to students, to visualize the performance and appearance of the technologies in simulations of real-life installations and learn more about their potential.

Take AirRenew, for instance. An architect or contractor could select it for a project based on the recommendations of others, but being able to experience firsthand how its ability to perpetually scavenge formaldehyde and other VOC emissions from indoor air and trap them inside walls is a huge advantage. This feature greatly improves indoor air quality by removing that very familiar “new-home/building smell” produced by VOC content in finishes and various furnishings, as well as the headaches, nausea and other health issues that sometimes accompany it. By viewing a completed installation of this and other products and learning more about them on-site, the specifier can make more informed, confident decisions, ultimately leading to better results on projects.

Frauhofer CSE is slated to open to the public later this year. For more information, go to  cse.fraunhofer.org. For more information on AirRenew, visit http://www.certainteed.com/products/gypsum.
