Better Sustainable Habitat -Canada a World Leader

CertainTeed is pleased to introduce Building Knowledge insights that are focused on the Canadian market.  This is the first of many blogs that we will publish with our Canadian experts.

Canada represents the highest gypsum use per capita in the world and contributes significantly to sustainable habitat.  With the implementation of Toronto’s Green Standard (TGS) on January 1, 2014 the game was changed for buildings in Toronto which is the 4th largest city in North America.  This Green Standard mandates energy efficiency that will move the needle significantly and make Toronto a leader in sustainability.

TGS is a two-tier set of performance measures with supporting guidelines related to sustainable site and building design for new private and public developments. Tier One is mandatory and requires an increase in energy efficiency by 15 percent.  Tier Two, which is voluntary, requires a 25 percent increase in energy efficiency above the Ontario Building Code for Part 3 large buildings which is the highest in North America.

WHITE = the project has had preliminary renderings, but no application has been  submitted.
RED = the project has submitted an application to the city.
GREEN = the project has been approved, but has yet to start.
YELLOW = the project is currently in sales.
BLUE = the project is currently under construction

The challenge is to identify solutions at the pre-design stage.  This can be done with various gypsum wallboard products that deliver energy efficiency, improved indoor air quality, better acoustics, mould and moisture control and increased durability with a reasonable percent of window to walls which  significantly improves energy efficiency.

With the ultimate goal of providing superior comfort and health for building occupants manufacturers are solving critical interior problems in buildings and homes through new innovative wallboard solutions.

 

Tide Turns for Home Devastated by Hurricane Sandy

IMG_4853The Sunset Green Home, once a charming 1940s cottage resting five feet above sea level, was damaged by Hurricane Irene in 2011 and decimated by Hurricane Sandy in 2012. In 2015, however, the tide will turn as it will be rebuilt as a sustainable, energy-efficient home registered through the LEED® for Homes Green Building Program. The certification goal is actually LEED Platinum.

Kim Erle, the homeowner, also happens to be a LEED AP. She and her team of architects and designers recently identified CertainTeed as a company with a range of industry-leading products that would work well in her sustainably built home. We are pleased that AirRenew® Essential Indoor Air Quality (IAQ) gypsum board, FortiCel™ Mold Prevention System, SMARTBATT™ with MoistureSense™ Technology batt insulation, GlasRoc® Diamondback® Tile Backer, and CertaSpray® open and closed cell foam were all specified for this project.

IMG_4722These products are bringing Kim and her family peace of mind. She says mold was visibly rampant in the walls and floorboards when the remains of her cottage-style home were demolished. She’s convinced this mold was there before Hurricane Sandy took out the house. Many of the products she has chosen, including ours, are there to help mitigate her mold concerns. The specified FortiCel, for instance, is a protective coating that is sprayed into the wall cavity to help prevent mold growth on structural framing surfaces. SMARTBATT also helps reduce the potential for mold and mildew growth as it comes with a smart vapor retarder that changes its permeability with the ambient humidity condition. This means the wall can essentially breathe when SMARTBATT senses moisture that needs to be released from within the wall. To further improve indoor air quality, the AirRenew wallboard will actually clean the air in Kim’s house by capturing VOCs and converting them into safe, inert compounds that safely remain within the board for up to 75 years.

Her home will be under construction through June, at which time the family hopes to move in for the summer. Check out her blog for updates on the project. It’s a great study on residential LEED design and construction.

Q and A at International Builders’ Show (IBS) with Expert Ron Hazelton

During IBS our Meet the Experts sessions gave show attendees the opportunity to get their questions answered.  Our MC, Ted Brunson talked with TV’s “House Calls” host Ron Hazelton

What trends are you seeing with regard to Home Improvement?

???????????????????????????????One of the reasons I enjoy coming to shows like IBS is because consumers are becoming very savvy buyers. They spend much more time researching products for their home than depending on building professionals only to guide their buying decisions.

I am always looking for new products that solve problems in the home such as indoor air quality, acoustics, energy savings and comfort to share with my viewers if I believe that they will benefit them and their homes.  CertainTeed always has innovative products that I can share with my viewers whether they are building professionals, DIYers or consumers.

Specifiers Unite: Free Webinar on Comfortable Environments through Sustainable Design

Sustainable design, indoor air quality, controlled ventilation and thermal comfort are the topics du jour for a free webinar led by building scientist Lucas Hamilton on October 1 at 2 p.m. EST. While many of CertainTeed’s courses are offered through the Academy of Continuing Education, we are delighted to team up with the Construction Specification Institute (CSI) for this webinar, titled “Commercial Building Design: Comfortable Environments Through Sustainable Design.”

The presentation will review core principles of sustainable design and describe green building concepts and rating systems. Participants will learn ways to improve indoor air quality through controlled ventilation and material selection and how to create superior acoustical environments through sound control design practices.

More specifically, the learning objectives include:

  • Explain the concepts of green building through sustainable design and describe the three principles of sustainable design.
  • Understand credit categories for a green building rating system.
  • Describe several factors affecting thermal comfort.
  • Understand ways to improve indoor air quality through controlled ventilation and material selection.
  • Explain how to create superior acoustical environments through sound control design practices.
  • Review design strategies that help create a high quality visual environment.

Understanding and Improving Indoor Air Quality Webinar

We, as a society, spend 90 percent of our time indoors. It is extremely important that the air inside our buildings, both residential and commercial, is providing the healthiest environment possible.

I will be hosting a webinar on Tuesday, April 8 from 3:00 – 4:00 pm EST on the topic of Understanding and Improving Air Quality.

This is a newly accredited program for us taking a deeper dive into the topic which is touched upon in other webinars that we have offer.  It is a more focused discussion on how to improve indoor air quality. 

We have talked about this topic and provided education on what indoor air quality is but this program will identify actual steps that can be taken to improve the quality of indoor air.

Let’s get together – inside – and explore the ways to improve our indoor air.  You can sign up right here for the webinar Understanding and Improving Indoor Air Quality (IAQ) – (GBCI Approved).

Come with questions and try to stump the presenter!

The Art of Building Science – Soup to Nuts Webinar Series

We are trying something new that we hope is helpful for those of you who would like to take a deeper dive into Building Science but can’t take time out of a nutty work day to do so.

Because I live Building Science every day, I occasionally lose sight of the fact that not everyone sees how all of this information works and fits together.  Sadly we live in a bullet point world so let’s give the big picture the opportunity to talk. Let’s give the silent masses the opportunity to ask questions and engage with folks who work with this knowledge on a daily basis in real world scenarios.

The early evening timeframe for this series may have particular value for younger architects and building professionals who do not get to take time out of billable hours but could jump online at the end of the day.

We are offering the opportunity to see the Big Picture of Building Science through a series of three webinars starting at 5:30 pm EST over the next three months that will take you through topics such as Heat Flow, Moisture Flow, Air Flow, Indoor Air Quality, Evaluating HVAC or Mechanical Systems in the Building Envelop and Sound Control Problems.

Be forewarned, each webinar is a half hour longer than the last.  It is like a three course meal that will leave you both full and wanting more.

The first session will be held on Wednesday, March 12 from 5:30 – 6:30 pm EST.  If you are looking to expand your knowledge of Building Science, this accredited course is for you!

Wall Assemblies for Maximum Efficiency: How Many Layers is Too Many?

SimplexOPTIMABuilding professionals spend a lot of time dealing with production construction which has dialed in efficiencies and productivity to provide the maximum assembly for the cost per square foot.  The reality is in standard construction you build things in five or six layers. This is the standard in terms of building a wall system more efficiently and we have gotten it down to a science.  Generally a six layer home will give you a solid, energy efficient, comfortable home.

Occasionally, I work with builders on projects that remind me of possibilities beyond what is the status quo.  I recently had an opportunity to work with a builder who was building a custom home whose wall systems had 13 layers.  This wall had so much redundancy and robustness built into it that I just had to ask for a chance to visit the project and see this masterpiece being built.

This was the homeowner’s instruction: They wanted a thick wall, they wanted a silent wall, they wanted a highly efficient wall for them to own.  That’s one of the key’s to this discussion- the owner is focused on what comes afterwards- not what happened before. To achieve this goal the builder is employing a combination of traditional masonry materials and cutting edge products and systems.   

In a similar fashion, a project that CertainTeed has been involved with at the Navy Yard in Philadelphia with Penn State achieves a similar goal but in a lighter and perhaps less massive assembly – to create a highly efficient wall system that can provide comfort, improve indoor air quality, better acoustics but, and here’s the rub- to still be affordable by more typical consumers.  This was done by using a 2 x 8 construction – providing a deeper wall cavity – A Blown-in-Blanket Insulation System, Weather Resistant Barrier, a Smart Vapor Retarder and Air Barrier System, a Wallboard Solution, Rigid Insulation on exterior and Insulated Vinyl Siding. This created an R30.5 exterior wall.

In both homes, products were used to address acoustics, indoor air quality and moisture control.  Do you need 13 layers?  Probably not but the pressure is certainly going to be on what layers remain to do more than they have in the past.

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.

Building Knowledge at AIA 2013 — Expertise that Inspires

LucasAIA13Upon completion of a CEU Course at AIA 2013 on “The Future of Building Materials and Their Impact on How We Build”, Building Scientist Lucas Hamilton was asked the following question:

“What does air tightness have to do with air quality? How does the tightness influence the air inside?  It doesn’t make any sense?”

When the building envelope was leaky, we had three to four times the volume of the building being changed every hour by fresh air from outside — uncontrolled in the building envelope. Now, with tighter buildings we don’t allow that.  So, you have lost all the fresh air you had coming through the walls. That’s why it is so important. That is the influence today.

If you’re at AIA, stop by booth #2108 to continue the discussion with Lucas and our team of Building Knowledge experts. Also, feel free to add your thoughts below — comments and questions are always welcome!
