A Case for Spray Polyurethane Foams Contributing to Points in the LEED System

certasprayccappsmall409x237We are seeing an increase in the use of spray foam insulation in both commercial and residential construction both by itself and in combination with other insulations because it adds a new dimension to improving the energy efficiency of buildings especially when applying for LEED certification.

The proper use of spray foam will change your performance when you do energy modeling of your building with ASHRAE 90.1. It contributes in many ways in addition to good thermal resistance. It also has the potential for reducing whole building air leakage when installed where buildings leak air. The effect will show up in the energy modeling results.

There has been recent good news with regard to the spray polyurethane foams and LEED. The Spray Polyurethane Foam Alliance has completed Environmental Product Declarations (EPDs) for both open and closed cell spray foams among its members. This is aggregated data across the members of the Alliance giving you the documentation for use with LEED v4. These EPDs are available from the members who participate.

I strongly urge all of you who haven’t yet to build a library of transparency documents for the products you like to use. There is no single source repository of this documentation across manufacturers and service providers so you’ll have to do much of the seeking yourself. Once you have created your own library, make sure someone gets the task of maintaining it to ensure all the documents you are curating are up to date and accurate.

Homes for Our Troops, A Cause to Celebrate

During this busy time of year let’s pause and focus on that for which we are grateful. I am grateful for the blessings that come with working for a company with compassion.  As a manufacturer of building materials, CertainTeed donates to several charitable organizations at the regional and corporate level. This year, CertainTeed proudly made a multi-year commitment to Homes for Our Troops.HFOTlogo_RGB_url2014-291x300

Homes for Our Troops is a national non-profit organization dedicated to building specially adapted homes for severely injured Veterans across the nation. The organization is committed to helping American heroes rebuild their lives. Our involvement is through product donation; however, there are many ways individuals can help, too.

This holiday season 10 Veterans are receiving their own specially adapted home. When you stop to think about what this means for these individuals and their families, it is humbling. The homes are provided mortgage-free to these soldiers who have returned home with life-altering injuries. Surely this is something for which we can all be thankful.

Homes for Our Troops raises money and provides building materials and professional labor to coordinate the construction of state-of-the-art homes so Veterans can live more independently. The specially adapted homes help empower these Veterans so they each can focus on their recovery and returning to their life’s work. Read more about these heroes and their post-war journeys at www.hfotusa.org.

So yes, this holiday I give thanks to Homes for Our Troops, American soldiers, and working for a company that allows me to be a small part of this generous and necessary effort.

 

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:

  • The main properties of acoustical ceilings, their function and performance, and how they are tied to positive outcomes in healthcare facilities, schools and places of business.
  • How to calculate the Noise Reduction Coefficient (NRC) when determining the acoustical performance of a product and compare acoustical materials as they relate to sound absorption and frequency.
  • The Luminous Reflectance Factor of acoustical materials as it relates to sustainable work environments.

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.

Green Thought Leader Bob Marshall, manager, Building Science, CertainTeed Gypsum Canada

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?

Bob MarshallIn Canada, we have a much different view on energy efficiency and zero energy for buildings. Targeting energy efficiency is not only a priority but a regulatory requirement in Canada. The government is not waiting for people to take the 3 percent of the buildings that are LEED to a higher energy efficiency, they are mandating it in regulation.

Toronto, where I am from, is the fourth largest city in North America and has the highest energy efficiency standard for buildings in North America. It is 25 percent higher than the Ontario building code which is quite high in comparison to other parts of North America. We are following the course that Europe has taken and making it law to implement this for all buildings.

We will be the first jurisdiction in North America to mandate the maximum energy use intensity in a building and we are doing this for all buildings. It will be part of the next building code requirements.

We need to change the game with regard to the goals for energy efficient buildings and mandate it.

Acoustic Ceilings: Classroom Acoustics Webinar and Panel Discussion

ASSAABLOYWhat impact can you as the designer bring to a classroom setting given that you are not going to be teaching? One of the things you potentially bring is the ability to impact the environmental acoustical value of the space.

The 21st C classroom is a more diverse place than ever before. With the mainstreaming of children with learning disabilities, physical challenges and language barrier issues, it is more important than ever to have an acoustically efficient environment. To create a design which does not addresses the lowest common denominator just seems wrong.

On Wednesday, November 12 from 12:00 – 1:30 pm ET CertainTeed will conduct a Classroom Acoustics Webinar followed by a panel discussion that will explore, in depth, the challenges of educational space design. Attendees will learn:

  • Why Acoustics Matter
  • Fundamentals of Sound and Acoustics
  • Understanding the Primary Acoustic Problems in Schools
  • Background Noise
  • Reverberation
  • Signal-to-Noise Ratio
  • Classroom Acoustics and LEED
  • Challengers and Solutions through Academic Research

Robert Marshall, Manager for Marketing Technical Services for CertainTeed Ceilings, has spent a career working with acoustical ceilings as a private contractor and now in the manufacturing sector. He will share his vast knowledge on this subject and will also participate in a panel discussion lead by Mark Fowler, Editorial Director, Walls & Ceilings. Also on the panel will be:

  • Christopher Pollock, PE, CTS, LEED AL BD+C – Partner, DC Regional Director, Cerami & Associates
  • Edward Dugger, AIA, ASA, NCAS, INCE – Senior Acoustical Consultant, Edward Dugger & Associates
  • Alana F. Dunoff – Associate Adjunct Professor of Facilities, Tyler School of ArchitectureTemple University
  • Dawn R. Schuette, FAIA, LEED AP – Partner, Threshold Acoustics

Green Thought Leaders – Robert Marshall, manager, marketing technical services, CertainTeed Ceilings

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?

I think the most compelling thing is the marketing of transparency. Five years ago all the issues that we talk about in transparency, had we had them at that point in time, we couldn’t have given this information away.  But today because of the inclusion in LEED, the references to transparency that are now part of Version 4, everybody we go to visit, either knows about it and wants to know if we have it or has heard about it and wants us to tell them about it.

It has opened up a whole new avenue for us. For CertainTeed and Saint-Gobain, we have a corporate-wide movement toward a transparency that is unprecedented from a global perspective that will trickle down to all our divisions.  At some point, there will be Life Cycle Assessments, Certified Environmental Product Declarations and Health Product Declarations that will be part and parcel of everything that we sell.

Green Thought Leaders – Drew Brandt, vice president, Marketing for 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?

Drew Brandt 3When you look at sustainability you are looking at the structure itself – the longevity, the life, how it works – things are becoming systems. It’s not about individual products anymore so as you pull the systems together you have to understand how they operate together. Permeance is extremely important. As you look at air tightness with regard to moisture management, we now have to manage the moisture flow within that house. As moisture is generated inside and you need to get the moisture out of the house. You also have to make sure that moisture is not coming into the house from the outside.

Air tightness and moisture management are the most critical aspects of building design right now when it comes to sustainability. It affects everything from the products that are used to build the house, the comfort of the homeowners, and how the overall systems work.
