Lucas Hamilton: The most compelling thing for me is transparency and transparency documentation. I think it is one of the coolest things going on because it drives human behavior. It drives consumer behavior because now they have a chance to choose materials that they can get information on and it drives manufacturer behavior because when you have to show the world what you are doing you are more inclined to make positive changes with regard to the impact you are having on the environment. It pushes and pulls and does it for all the right reasons and without mandate. It uses the best part of our human nature on both sides. I think five years from now we will look back and see just how much of an impact is has made on how we make and purchase products.

Hoteliers Take Heed: LEED is Good for Business

BlogA recent study published by the Cornell University School of Hotel Administration provides empirical evidence that LEED-certified hotels make more money per room than non-certified competitors.

The U.S. Green Building Council’s (USGBC) Leadership in Energy and Environmental Design (LEED) rating system has guided the building industry’s turn toward sustainable design since 2000. From its inception, the question has never been is LEED good for the environment. That’s a given. The question has always been is LEED good for business. Certainly the hotel industry has already embraced sustainable design to varying degrees, but evidence supporting its business practicality will surely spur on future green efforts.

What Cornell researchers did for this study was compare the performance of 93 LEED-certified hotels to that of 514 comparable non-certified competitors and found that those certified had higher average daily rates and revenue per available room, at least for two years following the certification.

This is interesting news for the hotel industry. Until now there has been little data linking LEED certification to business performance. The Cornell University study’s findings mesh with McGraw-Hill’s 2013 Green Retail and Hospitality report, which looked at annual operating costs, asset value, and ROI. This data, coupled with USGBC’s new LEED scorecard specific to the hotel industry, could bring forth lasting change toward sustainably designed hotels.

As the manufacturer of a complete portfolio of gypsum board, insulation and finishing products, we share the responsibility to help hotels meet LEED credits. That’s why we offer building materials that allow hotels to effectively address important environmental issues like indoor air quality, thermal performance and acoustics.

It’s our perspective that the Cornell study will serve as a catalyst for hoteliers to support the construction of sustainably built hotels. The proof is in the Cornell report, the guidance is in the LEED scorecard, and the products are on the market. Seems like now is a good time for hotels to go green.

Don’t Risk Missing Points in LEED V4

LEEDv4If I put on my promotion hat on for a minute, I urge anyone using LEED to be aware of the transparency reporting changes between LEED 2009 and LEED V4. Both reward transparency points but in LEED 2009 they are found under the pilot libraries but in LEED V4 they are migrated down to materials and resources credits.

Since both programs will be in play until mid- 2015, it is important to know where to properly apply these transparency points from manufacturers that provide transparency documentation.

You can be awarded up to six points for transparency so, believe me, this is not something that you want to walk past these because it can cost you a fortune to make up six points somewhere else.

If you need to know the differences between LEED 2009 and LEED V4, I am running a webinar entitled Understanding LEED 2009 v. LEED Version 4on Tuesday, May 6 at 2:00 pm EST. My webinars are free of charge and qualify for AIA and GBCI credits.

In the spirit of transparency, I will cover the following objectives:

  • Identify key improvements in LEED version 4 compared to LEED 2009. Describe new credits applicable to building products and their requirements
  • Understand the new importance of products with Environmental Product Declarations (EPDs), Health Product Declarations (HPDs), and Extended Producer Responsibility (EPR) programs
  •  Identify products that improve energy performance, acoustics, daylight, waste management, and thermal comfort
  • Explain the importance of selecting low emitting products and materials to meet updated credit requirements

If you build for LEED, you won’t want to miss this session.

Small is Beautiful in this Contemporary Cabin from Simplex Homes

When you start to think about downsizing  you may want to consider modular construction if you are building.  At Greenbuild this year, the Green Zone exhibited a wonderful option.Simplex House

The Greenbuild Cabin, designed by Resolution:4 Architecture and built by Simplex Homes, was an excellent example of more efficient living similar to the types of residential options you would see at the Solar Decathlon.  Attendees at Greenbuild could see products at work in a modular one-room retreat that was aesthetically very pleasing.

The 806-square-foot cabin is designed to have a strong connection to the exterior, with abundant natural lighting achieved through low-e, Argonne-filled, double-pane glass. With a LEED Platinum certification as the goal, the cabin employs a number of green technologies, including rainwater collection, a greywater system, photovoltaic array, EPDM rubber membrane roofing system and a super-insulated envelope.

The cabin houses a fully functional kitchen and, through its creative use of space and natural lighting, invites residents to live large.  

Lessons Learned at the GreenZone Pedia-Pod

Screen shot 2013-11-26 at 11.29.23 AMAt Greenbuild 2013, Building Design + Construction magazine delivered a life-size GreenZone Pedia-Pod to the show, where more than 30,000 attendees had the opportunity to explore this unique facility. The 14×42-foot module was fabricated by NRB of Ephrata, Penn., using a permanent modular construction technique. CertainTeed was proud to included in the stringent sustainable product specifications, which included Sustainable Insulation, AirRenew IAQ Gypsum Board and Symphony Ceiling Panels.

While touring the facility, I also gleaned several eye-opening insights on healthcare design and construction trends:

Constant exposure to indoor lighting can impact children’s eyes — which are still developing. Patient controlled lighting or lighting that mimics a circadian rhythm can result in a better healing environment;

Patient rooms are becoming more family-centric by incorporating flexible furniture solutions. In the GreenZone Pedia-Pod, this was accomplished by the a wall of library shelving that rotated to reveal a hidden bed that would allow parents to stay with a sick child; and,

Modular medical units can offer more flexibility in providing care to the community, since they can efficiently be deconstructed and relocated.

An Insight from Green Building Guru: David Gottfried

GottfriedAt Greenbuild 2013, we were thrilled to welcome David Gottfried, the founder of the U.S. Green Building Council to our exhibit. His visit coincided with the launch of his newest book, “Explosion Green”. In this excerpt from Building Design + Construction magazine, David offers the following advice to green building professionals:

Don’t give up. We started with nothing — no money, no board, no brochure, no green building rating system. A lot of people did not take us seriously. However, we were able to collect those who had passion, a spirit for change and wanted a bigger purpose in life. And then, we supported each other when mountain climbing got steep and we kept at it. We found our way and invented the fasting growing industry for changing earth and the economy…and built a core around the world of millions of people. Stay the course and don’t give up…

Well said, Mr. Gottfried. We agree and look forward to reading your new book!

LEEDv4: Empowering Consumers through Greater Product Transparency?

HPDLogoThis week, I’m in downtown Philadelphia for Greenbuild 2013, which attracts more than 30,000 building and design professionals from around the world. The event also serves as the platform for the official launch of the U.S. Green Building Council’s new LEED®v4 standard, which calls for further environmental transparency in the built environment. While much of the buzz around LEEDv4 is within the green building community, I believe that the average consumer will benefit greatly from these new standards. Why? Because increased transparency translates into a more empowered consumer base.

Take the food industry as an example. For the most part, today’s consumers are label readers and are increasingly conscious of what is deemed healthy and what is not. They are demanding more disclosure of food ingredients such as trans fat. They are thinking twice about eating foods that are impossible to pronounce. They are the reason that most super markets have growing in-store real estate dedicated to organic foods.

How can we harness this energy and apply it to the physical environment where we live, work and play? I believe that Health Product Declarations (HPDs), which play a key role in LEEDv4, are a great start. HPDs comprehensively report information about the health impacts of each ingredient used to manufacture a building product. With this, architects, designers and contractors — as well as end users and consumers­— will be equipped with valuable information about their surroundings.

Not yet familiar with HPDs? Check out www.hpdcollaborative.org or visit www.ctpressroom.com to learn more about CertainTeed’s industry-first HPDs for its ceiling products.

 

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.

An Unsettling Modular Construction Myth Is Put To Rest

SimplexOPTIMARecently, I had the opportunity to debunk an industry myth that blown-in fiberglass loose-fill insulation is not a viable option for new modular home construction, as it might settle and lose R-value while in transit between the modular home production facility and the jobsite. This was one of the reasons modular home builder Simplex Homes had avoided using blown-in insulation on their projects for years. This year, however, they found themselves working with our OPTIMA® blown-in fiberglass insulation while building a Net Zero Energy demonstration structure at The Navy Yard in Philadelphia as part of Penn State’s GridSTAR Experience Center.

The plan was to build, insulate and roof the shell of the structure, using modular construction techniques, at the Simplex Homes production facility in Scranton, Pa., and ship it by truck to Philadelphia. Having never used OPTIMA in a modular construction application and concerned about the settling rumor, the builder consulted me for assistance in the design and assembly of the high-performance wall assemblies. I designed for them a high-performance 2×8 wood-framed wall assembly, which offered a total insulation R-value of 35.4. A key component of this assembly is a Blow-in-Blanket® System (BIBS) for the wall cavity featuring a 7-1/4-inch-thick layer of OPTIMA insulation.

With on-site assistance from one of our product engineers, the Simplex Homes crew was able to easily build and insulate the wall assemblies. The building’s shell was trucked to The Navy Yard this past spring, where the remainder of the interior finishes were added. An inspection after its arrival confirmed that the insulation had not moved an inch. Simplex Homes was impressed by their first experience installing OPTIMA and is now looking forward to working with the product in future modular construction projects.

The bottom line is that fiberglass loose-fill insulation is naturally inert and therefore will not settle or lose R-Value over the years, as long as it is installed properly at its full designed thickness. Blown-in fiberglass loose-fill insulation is an asset to any modular construction project, offering unwavering superior R-value, fire resistance and acoustic control for the life of a structure.

Now that we’ve put this myth to rest, what topic should we tackle next?

Building Knowledge AIA 2013 — Expertise that Inspires

GreniteSamples_StackedFullFollowing the CEU Course at AIA 2013 on “Sustainable Surface Materials: The Value of Engineered Stone” presenter Diana Ohl from Saint-Gobain Grenite was asked:

“What are the primary reasons for choosing engineered stone?”

A sustainable engineered stone product has up to 80 percent recycled material.  The measure of hardness is a 7.5, which is the highest in the marketplace. The product has almost a zero maintenance factor which can be critical in buildings that sustain heavy wear and tear, such as dormitories, retail establishments and restuarants. Also, when looking at the return on investment – if you are replacing countertops frequently because of damage – the manufacturer guarantee of Grenite is 15 years.

 If you’ve worked with engineered stone on a project, we’d like to hear about your experience. Comments are welcomed below or stop by booth #2108 at the AIA expo to chat with Diana and our team of Building Knowledge experts.
