Don’t Stop at the Surface with Moisture and Mold Damage

1316551358_254450912_4-Residential-and-commercial-Flood-Water-Damage-services-free-est-8888110187-ServicesMold Awareness Month Tip #2: When you see signs of moisture damage either on the exterior or interior you can’t just address this at the surface.  You have to keep digging until you get to dry materials.  If that means tearing out the drywall and the insulation until you get to something dry, so be it. You can’t just fix the surface because it was wet. If you have to replace materials following moisture damage consider using a mold and moisture resistant drywall and a smart vapor retarder with your insulation to add protection to your wall assembly. You will be building in more robustness to an area of your home that is apparently susceptible to moisture intrusion.

That’s from the outside too.  If you find some water damage around your window and you tear it out you can’t stop there.  Take your screwdriver or awl and probe the wood behind it to find out how far the damage goes. If you don’t correct the problem at the source and replace all the damaged materials, the chances of mold occurring in this area are very good..

So, don’t stop at the surface or just treat the symptoms.  You have to exhaust the symptoms and get to the source.

Remember, if you see moisture damage whether inside or outside the building don’t stop digging and probing until you get to dry.

If It Smells Bad It Is Bad

 September is Mold Awareness Month and I thought it would be a good time to provide some helpful tips about mold.  This was prompted by a discussion that came up the other day when I was conducting a webinar on “The Future of Building Materials and Their Impact on How we Build”.  Mold is not always visible but early detection of a mold problem is critical to the health of a building.

Mold-in-basement2Mold has a long history, in fact, references about mold can be found in the Bible (Leviticus 14: 33-53). When you are dealing with living things that have that much staying power, it is clear that you can’t or won’t get rid of them easily.  In a previous blog, I discussed the four things that mold needs to grow: the right temperature, sufficient water, oxygen and food.  But you can control the growth by eliminating one of the elements. If the problem is moisture in the wall cavity you need to remove all the wet insulation and drywall and thoroughly dry the assembly.

One of the best ways to identify a mold problem early is through smell. Often you can smell it before you see it. If you smell something that doesn’t smell right, trust your instincts and check it out.  This is your learned response to protect you from dangerous materials.

If you think you may have mold, get on your hands and knees and sniff around the outlets in your walls. If you have it – you will smell it.  Also, check areas that do not have adequate ventilation (closets or other spaces with no vents or registers).

If you smell it that means the mold spores are airborne and that is when they present the most health risk. When it’s dormant you are not going to smell it but if the spores go aerosol, you need take action.

 

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.

Glass Bottle or Paper Bag?

If you wanted to keep something for 50 years would you keep it is a paper bag or a glass bottle?

This question came from a recent architect training I conducted in New York. I was engaged in a conversation about wall systems and sustainability with this group and the discussion moved to durability in relation to sustainability.

I posed that question and the response was a glass bottle. However, a case can be made for both.

Many of the passive energy saving measures we employ in our buildings can only be accomplished effectively during initial construction.  As an example; it is very difficult to add insulation to side walls over time because the cavity is designed, constructed and closed in.  If you want durability and longevity you better be building something upfront that will last at least 50 years.

To that end, do not employ difficult to replace materials that are not intended to last as long as the wall you are building. If you haven’t figured it out yet we were talking about different types of insulation.

If you can’t see it, inspect it, or fix it, you had better be sure it’s going to be around longer than you are.

Your thoughts are always welcome.

Cultivating Green Jobs in Solar Energy

GridSTAR_SolarThe Navy Yard in Philadelphia has evolved as an economic development powerhouse, attracting more than 10,000 jobs since the former Navy base began its transformation some 20 years ago. However, did you also know the campus is playing a critical role in supporting the development of green jobs?

For the past two years, I’ve been heavily involved with the GridSTAR Renewable Energy Training Structure, which includes a first-of-its-kind solar training facility. Slated for completion next month, the facility features our Apollo photovoltaic roofing system along with advanced battery solutions from Solar Grid Storage and off-grid power distribution equipment developed by Eaton. Penn State University as well as other project partners will use the facility as a hands-on classroom and research laboratory.

The facility is filling an important void in furthering the adoption of solar technologies. It’s estimated that 40 to 45 percent of power and energy professionals and educators may retire within the next five years. While at the same time, 92 percent of Americans believe the U.S. should develop and use more solar energy. To help fill this gap, projects such as the GridSTAR Renewable Energy Training Structure, will help ensure that roofing contractors, linemen, electricians, power system technicians and engineers are primed and ready to support this demand.

Most importantly, the facility is an excellent example of how public-private collaboration is driving workforce development, innovation and a more energy independent future. Is your community prepared for the next generation of green jobs?

Building Knowledge Experts at AIA2013 – Expertise that Inspires

AIA2013CertainTeed Technical Marketing Manager for Ceilings Bob Marshall conducted a session at AIA2013 on Ceilings in the Health Care Segment.  During the presentation while Bob was discussing the noise levels in hospitals and how it impacts healing, the question was raised:

“Why do we accept higher noise levels in hospitals if we know that it impacts the patients’ ability to heal?”

Two things work in our favor. Acoustical standards and guidelines are well documented and hospital administrators are getting validation regarding just how much acoustics matter and they are starting to make better choices when upgrading their facilities. We have to keep in mind that hospitals are very competitive but we are starting to see changes that have positive effects on patients and recovery. Rooms are painted in pastels now with artwork on the wall so administrators are starting to make the environment more pleasant for the patients.  At some point, they will have to address the noise levels as they relate to healing to continue to remain competitive. There is research that will speak to just about every architectural decision from an interior perspective. We are just validating and giving them the tools to go ahead and sell the acoustical benefits for making these changes.

If you have a question or comment, we would love to hear from you. Although AIA 2013 is over, we know these questions will continue to be raised.

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!

Changing the Sustainability Game in Philadelphia

GridSTARHouseBackPhiladelphia is making great strides when it comes to sustainability. The world’s largest green building event — Greenbuild 2013 — will attract more than 30,000 building industry leaders to Philadelphia in November. The city has received national recognition for its recycling programs. New codes and tax credits are fostering more sustainable building practices. And, there’s a hotbed of research and innovation underway at The Navy Yard in Philadelphia.

With our North American headquarters just outside of Philadelphia and as a sustainable manufacturer, we fully embrace the city’s push to become “America’s Greenest City”. We have invested time and resources into a game-changing, smart-grid project that can move the needle on Net Zero Energy in construction.

Led by a collaboration of researchers, manufacturers and economic development officials, the GridSTAR Center will roll out in three phases — the GridSTAR Net Zero Energy Demonstration Structure, a solar training center and an electric vehicle (EV) charging station. These buildings are powered by an energy storage system that captures the power and disperses it as needed.

For more than a year, I have been involved in the planning and construction of the Net Zero Energy Demonstration Structure, which will be a hub for CertainTeed Building Science testing and research on energy efficiency and indoor environmental quality. The structure also offers a valuable platform to further understand and optimize how our products work together — including photovoltaic roofing, solar reflective roofing, fiberglass and spray foam insulation, foundation drainage and waterproofing systems, insulated vinyl siding, water resistive barrier and gypsum board.

From a broader perspective, the GridSTAR project is a testament to the power of public-private partnerships. In this case, the project includes a consortium of representatives from Penn State, the U.S. Department of Energy, Commonwealth of Pennsylvania, Philadelphia Industrial Development Corporation, DTE Energy and five leading building product manufacturers.

This truly is a landmark project that will influence how we build and power our homes in the future. If you plan to attend GreenBuild 2013 in Philadelphia, I recommend that you take the tour of the Navy Yard which includes this project. It is truly changing the sustainability game in Philadelphia.

Watch for future blogs on this project as we begin performance testing of the systems.

 

NAHB International Builders’ Show – Where New Products and Learning Collide

CertainTeed booth at IBS 2013

CertainTeed booth at IBS 2013

I am in Las Vegas for the National Association of Home Builders International Builders’ Show 2013.  I truly enjoy this show because it is a great opportunity to ‘kick the tires’ on products and learn about best practices taking places in the build community. 

With the new 2012 Building Codes that are starting to be adopted by states, it is critical that build professionals know the changes to the code requirements where they are building. It is also important to hear about best practices for achieving airtight assemblies and the best solutions for achieving maximum energy efficiency in the building envelope.

For IBS 2013, CertainTeed is focused on building knowledge. To assist with this, CertainTeed is incorporating in its booth (C2126) a Builder Resource Center making available building science and technical experts to share best practices but also to answer questions from show participants. If you come to our Resource Center you will be eligible to win a full day consultation by a building scientist on your construction site. 

At the booth, we will also have technical experts hosting “Ask the Expert” interactive sessions centered on building science, roofing, insulation, siding, gypsum and foundations. With the extension of the Energy Tax Credit as part of the fiscal cliff negotiations, contractors and developers who construct or renovate “dwelling units” (apartments, condos or single-family homes) that meet certain energy efficiency standards have access to a tax credit of up to $2000.

If you are attending IBS, make sure to stop by booth C2126 and pick our brains. I guarantee you will have a great learning experience as well as a fun time.

Don’t Forget the End Users When Building for Energy Efficiency

While at Greenbuild 2012 I was asked “What do you think is the most critical factor in ensuring a healthy, sustainable built environment?” My answer was posted on our Blog but there is more I want to say about this so here we go!

Users or occupants of high efficiency buildings need to understand and be a partner in the process because  ultimately they influence the  success or failure of a building’s efficiency over time. For example, Leadership in Energy and Environmental Design (LEED) for Homes will give you credit for and requires Energy Star performance which means certain insulation levels, certain air tightness and certain efficiencies on the mechanical systems (among other issues). The energy efficiency of the building is based upon a combination of highly efficient equipment and permanent passive systems.

When the active system wears out, if the consumers don’t appreciate the importance of the efficiency of that system on the overall performance of the habitat they are unlikely to take that into consideration when they have to replace equipment.  They can go from a high efficiency piece of equipment that made their sustainable building sing beautifully and perform wonderfully and stick in something that is on sale or is perhaps promoted by their contractor but with a whole different efficiency rating.  Now the building goes from being a Prius to being a Hummer simply because the driver wasn’t told the difference between the two.

In sustainability circles we often talk about “the Prius effect”.  This comes from the engagement of the driver with the car.  Once the driver understands the savings due to the offset of the electrical to the fuel and you give them real-time feedback, they began to drive against the machine to improve the efficiency. The build community needs to develop dashboards or other tools for high efficiency buildings so that end users can see the benefits provided by the systems.  That buy-in is critical to sustaining efficiency over the life cycle of the building.

There is no point in doing a sustainable building for someone unless you teach and show them how to maintain it. That is one aspect I especially admire about the Living Building Challenge. The Beauty petal has components which include inspiration and education. Couldn’t we all use a little more of both?
