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.

TORONTO (HIGH-RISE CAPITAL OF 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 CertainTeed Expert Kelly Warren

During IBS our Meet the Experts sessions gave show attendees the opportunity to get their questions answered.  Our MC, Ted Brunson pitches the following question to Kelly Warren, Senior Product Manager, Insulation

Explain what SMARTBATT™ is and the technology behind it?

Kelly and TedSMARTBATT is a kraft-faced insulation product that has an integrated vapor retarder in the product.  Not only does it protect your home from moisture entering the cavity in the winter but it opens to become vapor permeability in the spring and summer to allow vapor to escape the cavity. It is the best way to avoid moisture and mold from building up within the walls. The product senses the changes in the relative humidity causing the spray-applied coating to change molecular structure allowing the product to open and close and breathe based on ambient temperatures.

It is more important now with the changes in the building codes and the movement toward an air tight envelope. When you get to this level of air tightness it becomes extremely important to manage the moisture vapor in the home.

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.

???????????????????????????????With the Change in Building Codes, how is that impacting the Insulation World?

The focus on green building continues to grow and the building code changes reflect that. More and more questions are coming from consumers regarding what is inside the wall systems and what they can do to make their homes tighter and more efficient. Transparency is very important and in response to that we have created Environmental Product Declarations and Health Product Declarations for our wide array of products for all types of applications.  These documents are also needed for LEED (Leadership in Energy and Environmental Design) certification which is a standard for identifying more energy efficient buildings. The most critical areas are controlling the acoustics from room to room and managing moisture.  Insulation is about the complete comfort of a building.

As building codes continue to change, so do the options for insulating your walls – from fiberglass batts to spray foam to blowing wool and smart vapor retarders. It is important to find the right insulation to improve efficiency in any building.

Q and A at International Builders’ Show (IBS) with CertainTeed Expert Lucas Hamilton

Lucas and TedDuring IBS our Meet the Experts sessions gave show attendees the opportunity to get their questions answered.  Our MC, Ted Brunson(right) pitches the following question to Building Scientist Lucas Hamilton

What is CertainTeed doing to control the way moisture is entering and leaving the home?

We use a variety of different kinds of materials and technique in our products – including passive materials – that can change their properties from being vapor closed to vapor open to address this issue.  In a situation when a wall gets wet, the physical materials that make up that wall change and promote the removal of the moisture from that wall to dry it out before biological contaminants can take hold and compromise the indoor air quality.

We have always had moisture intruding in our built assemblies but as we have increased our efforts to conserve energy over the last 40 years we have reduced our tolerance for that moisture and drying potential.  If you can pump heat and energy into a wall you can dry it out. But if you bottle up that energy you reduce your tolerance for those intrusions.

 

Performance versus Prescriptive Compliance for Meeting Energy Codes

During some recent travels to work with builders, I spent time with a builder who was in the process of constructing walls and building envelopes with very little R value. These were thermal mass walls but with little R value. The builder was meeting the state energy building code through the performance path, which allows for more design freedom but involves more complex energy simulations and tradeoffs between systems, by using a highly engineered, very sophisticated, very expensive, high efficiency heating and air conditioning system.

The building when it’s completed will meet the code and the intent of the code which is to reduce energy consumption.  However, the weakness of this approach is that the equipment which is being used to meet the energy reduction goal codes will eventually wear out.  When that time comes, the owners of the building will be able to replace this high end equipment with a less expensive option since they are not under the jurisdiction or ‘watch’ of the building inspectors. This will decrease the energy efficiency of the building and possibly compromise its building code compliance.

This is one of the good things about the prescriptive path to the building code – that the elements that we choose, when properly installed, will meet the code and goals of energy reduction for the long term.  Things like thermal insulation when installed during the initial construction will always be in place, will always work and will never wear out. It will continue to perform over the life of the structure.

So while it is good to have options, remember not all options will give you the desired result over the life of the structure and that is worrisome.

 

Free Continuing Education Webinar: Acoustical Ceilings for the Eye, the Ear and the Mind

CTC_TCH_case study_409x240Unwanted noise in interior spaces can profoundly impact the way people work, learn and heal in the built environment. Well-designed interior spaces are key to combating this serious problem. Choosing the right ceiling panel material for a project makes a huge difference in managing the acoustical response of a room.

Studies also show that natural light that is more evenly distributed in a room can increase productivity. Ceilings manufactured with light reflectance properties can have a positive impact on the comfort of a room and decrease electrical costs.

To learn more, join our Building Knowledge Academy of Continuing Education (ACE) this Tuesday, December 16, from 1 – 2 p.m. ET, for a free educational webinar on acoustical ceilings. The course provides an overview of the principles of sound attenuation and light reflectance and can count toward CEU credits.

Robert Marshall, Manager for Marketing Technical Services for CertainTeed Ceilings, who has extensive experience with acoustical ceilings as a private contractor and now in the manufacturing sector, will lead the webinar. During this engaging discussion, you will learn:

Green Thought Leader Ted Winslow, brand product manager, CertainTeed Insulation

While at Greenbuild 2014, we asked our technical thought leaders the following question:

What is the most compelling thing happening in your universe with regard to sustainability? Ted Winslow, Brand Product Manager – Building Science, Systems & Technical Marketing, Insulation

???????????????????????????????The most compelling thing for me in regards to sustainability is seeing the evolution of how people are thinking of sustainability and energy efficiency. It is not just a one-stop solution and it is not about specific products. They want to have a holistic, systems approach to solving problems and want to know and understand how systems will impact the habitat as a whole. For example, if you increase the insulation in a building and make it tighter, how does that impact other things like moisture management? People are starting to realize that no matter how tight or impenetrable you build a building – moisture, for instance, will still potentially find a way in and what will need to be done to resolve the problem?

When you are dealing with a systems approach, each system created will be different depending on the needs for the structure. The possibilities are endless.

 

Green Thought Leader Helen Sanders, vice president, Technical Business Development, Sage Electrochromics

While at Greenbuild 2014, we asked our technical thought leaders the following question:

What is the most compelling thing happening in your universe with regard to sustainability?

Helen_Sanders_cropFor me the most compelling thing with regard to sustainability is the recognition of the human impact of day light. It is important for buildings to allow enough day light in but not to the point of being uncomfortable for the people inside. Day light is good for your health. It has been scientifically proven that if you don’t have enough day light at the right times of the day it can have significant health impacts such as increases in cancers, weight gain and mood disorders.

The design of buildings for the admission of day light is a 21st century imperative. We’ve got to try to design our buildings differently. In the 70’s and 80’s we started to build these massive footprints of buildings where very few people could be near a window. We did that because electricity was inexpensive so it allowed us to build bigger. Now we are seeing the downside of that from a health perspective. We’ve got to start doing something different with our building design to improve and harnass day light.
