Free net-zero webinar to provide ways to achieve energy efficiency goals in residential construction

Net Zero Demonstration HouseThanks to the pervasive use of sustainable building practices, the average homeowners’ ability to afford green homes and sustainable systems is finally within reach, as the cost of energy-efficient materials and renewable-energy equipment continues to fall. Case in point, according to the Solar Energy Industries Association the average price of an installed solar-power system has declined more than 50 percent since 2010.

Due to this attainable outlook, the U.S. Department of Energy says their ultimate vision is that by 2030, a consumer will have the opportunity to buy a cost-neutral, net-zero energy home (NZEH) anywhere in the United States — a grid-connected home that, over the course of a year, produces as much energy as it uses. However, this also represents a unique challenge for the architects and builders who will be tasked with creating, constructing and evaluating these climate-appropriate zero energy homes.

Enter CertainTeed’s newest free webinar, Net-Zero Energy Home: Design Strategies and System Optimization. The AIA-accredited online course takes place Tuesday, July 28 from 11:30 a.m. to 12:30 p.m. ET.

houseJoin me as I explore Pennsylvania State University’s award-winning, LEED Platinum, GridSTAR Experience Center project, completed last year on the grounds of the historic Navy Yard in Philadelphia. During the course, I will cover all aspects of this net-zero modular building that was designed and constructed using a unique combination of building materials, construction methods, energy management strategies and renewable energy sources. Learning objectives include:

  • Design strategies for pursuing a net-zero energy home
  • Describe tools used to create, construct and evaluate a climate-appropriate zero energy home before and after construction
  • Understand how to manage and interpret hygrothermal and demand response data for a single family residential home
  • Learn how innovative public/private partnerships are being used to advance building science research

This one drew a big crowd when I first presented it at AIA a few months ago in Atlanta. Register now, right here for Net-Zero Energy Home: Design Strategies and System Optimization.

Free webinar and expert panel to discuss strategies for optimizing workplace acoustics

SoloOfficeHow does noise affect the occupants of the buildings you design? A growing body of research shows that prolonged exposure to noisy office environments can negatively impact productivity and job satisfaction. Daily exposure to common noise levels in offices—50 to 60 decibels on average—can result in lower productivity and more missed work days. Did you know it can take up to 15 minutes for an office worker to regain concentration after being distracted by noise?

Even scarier, studies have linked high levels of office noise to increased stress, fatigue, accidents and illness. And statistics show that when noise hits 65 decibels, the risk of heart attack increases.

These are impactful figures, and they represent an opportunity for architects and designers to positively influence people’s lives during the design phase of an office project. CertainTeed Ceilings will gather an expert panel of leading architects, physicists and engineers in the field for a discussion on these topics during a free AIA-accredited webinar on Wednesday, June 17, from 12:30 to 2 p.m. ET.

During the AIA-accredited course, we will cover the primary acoustic issues in office environments and why acoustics matter, along with strategies for:

  • Designing flexible spaces that maximize sound containment and meet the privacy needs of conducting business
  • Address acoustics in environments in which sound quality is paramount, such as multi-media training spaces and conference rooms
  • Minimize noise intrusion in office spaces near or adjacent to high-noise areas or city traffic
  • Achieve acoustical quality, enhance productivity, and maximize the worker experience in open-concept office environments
  • Remedy sound problems in retrofit applications

Smarter Skins 2 for Higher Performance Buildings

CertainTeed is pleased to introduce Building Knowledge insights that are focused on the Canadian market.  This is the second blog published by one of our Canadian experts.

There is a push globally for all building codes, including at the international level, towards net-zero construction by 2030.  Europe, which is somewhat ahead of the rest of the world in energy efficiency, in pushing for mandatory zero energy requirements by 2018.

Canadians are experts in adapting to cold extremes, developing performance codes and innovative Building Skins solutions and, therefore, have many insights when it comes to achieving this goal. Accordingly, Toronto (See my previous Blog) and Vancouver are two of the top energy efficiency leaders in buildings in North America.

I had the opportunity to share building science insights to several hundred architects at Building Industry events in Vancouver and Toronto. In Toronto, the Ontario Association of Architects (OAA) are leaders with their own OAA+2030 program and I had the chance to co-present with a leading Architect, Contractor and University Team; the Smarter Skins 2 sequel in 2015 (SS 2015).  We know it was successful; as Smarter Skins 3 is already planned for 2016! What are some of the smarter building skin solutions from SS 2015 that contribute to higher performance and most important provide sustainable habitat for building occupants?

Halifax libraryIt is crucial to assess sustainable innovations at the design phase. You can’t change the window/wall ratio, air barrier system, insulation, or gypsum wall assemblies during or after construction, so it is critical to get it right!

SS 2015 presented the key principals for building smarter skin solutions including a case study from the CNN eye-popping and award winning New Halifax Library.

What is the principal lesson learned for large glass buildings if we also want to achieve higher performance?  It is the need for better architectural design that includes Building Science principles.  In the case of the Halifax Library, behind the glass skin veneer 54 percent of the walls are opaque walls constructed with insulation and drywall (See sample detail).  Therefore, by focusing on smarter wall and window assemblies, you can have inspirational views to the harbor and higher building envelope performance at lower cost.

In summary, design and build with smarter skins and your customers will come.  The recently opened Halifax Library has been experiencing Community usage approximately two times greater than expected and patrons are being inspired by the views to advance their knowledge.  Blog readers can also benefit from more Smarter Skins Higher Performance Buildings insights by following My Blog and attending CertainTeed’s  Architectural Insights Symposiums and Industry Partner Events that share smarter skins knowledge.

If you are working on creating smarter skins for all types of sustainable buildings, I would be interested in hearing about your projects and the materials and system skins you are using. For example, smarter skins are essential for more affordable mid-rise wood buildings now permitted in most Canadian Codes. Together, with Smarter Insights, we will achieve higher performance buildings today for our customers and move toward the goal of Net-Zero Energy.

Free Webinar Tackles Optimum Energy Efficiency Performance for Low-Slope Roofing Systems

FlintBoard-Polyisocyanurate-Roof-Insulation-CertainTeed-Roofing--Low-Slope-L-Sweets-514613The right insulation product and application method is fundamental to a well-designed low-slope roof system. Thermal needs of a building, energy codes, cost savings and insurance criteria must also be considered. For these reasons polyisocyanurate, also referred to as PIR, polyiso, or ISO, is the most prevalent form of low slope roofing insulation, specified primarily for use in offices, health facilities, warehouses, retail and industrial manufacturing facilities and educational institutions.

Learn more by joining me for a free, hour-long lunchtime webinar, Low Slope Roofing Featuring Polyisocyanurate, on Wednesday, May 27 from 12:30 – 1:30 p.m. ET.

During this AIA accredited, Health, Safety and Welfare (HSW) course, I’ll cover the background and current best practices of insulation in low-slope roofing applications with specific focus on this closed-cell, rigid foam board insulation.

New Information on Code Changes Requiring Cover Up of Exposed Floor Framing

download (1)In a previous Blog I discussed the change to the Building Codes that requires manufactured wood floor framing to be covered with a 30 minute radiant barrier because they will burn quicker in a fire.  This means covering up those unfinished basement ceilings as a safety precaution.  And as I stated earlier, I strongly recommend that builders be aware of the codes and requirements around this.

However, there are new ways to protect exposed TJI floor framing for fire reasons.  Instead of installing an entire ceiling, you can also install boards along the exposed sides of the web. I have seen this done and while I haven’t done the calculations, this would probably use less material and be more cost efficient than installing the entire ceiling.

I have been following this topic and I urge you to research and make sure you are aware of the options available.

If anyone has found other solutions, please let me know so we can share them with others.

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 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.

Q and A at International Builders’ Show (IBS) with CertainTeed Expert Ted Winslow

During 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 Brand Product Manager – Building Science, Systems & Technical Marketing, Ted Winslow, Insulation

???????????????????????????????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.
