Tips to Keep Your Cool All Summer Long

??????????????????????????????????Ah summertime, when the livin’ is easy. It seems like nothing can get you down except for maybe one thing – spiked electric bills. This summer, let’s beat the heat. See how you can help your family maximize fun without stressing your wallet.

Smart investments can help manage expenses in the summer, and for seasons to come. Achieve summer solace with an integrated solar roofing system. It’s an innovative, energy-efficient choice, and can generate most or all of the electricity a home uses during the day. In newer systems, unused power is transferred back to the power grid, which can reduce electric bills even further, and won’t compromise curb appeal.

My favorite features of summer are the long days and natural light. I love being greeted by sunlight in the morning so much, that I often find additional lighting unnecessary. I have discovered that switching out my incandescent light bulbs with compact fluorescent or LED bulbs decreases unwanted heat in the home and will save you money at the same time.

Whenever possible, get outdoors! Another great way to prevent rising temperatures in the home is to avoid using electrical appliances such as ovens. Instead grill outside; it’ll help reduce energy use.

Sometimes you need to cool off, and that’s when air conditioners can come in handy. When possible, use the AC sparingly, and never cool a vacant or unused room. I am a huge supporter of fans – ceiling or portable. Both create a healthy breeze and consume far less energy.

If you find fans can’t seem to keep your family comfortable, there may be a larger opportunity to find a sustainable solution. It might be time to add insulation to your attic or walls. Adequate insulation not only keeps your house warm, it can keep it cool, too. Insulated siding and housewrap can have the same effect. Combined, these products can help reduce energy bills and improve energy efficiency – making summer even sweeter.

Tips for Architects from the 2015 AIA Convention

I asked Lucas Hamilton, Manager, Building Science Applications for CertainTeed Corporation:

What is the most critical design element that Architects need to be aware of going forward in the built environment?

There are challenges in the new environment due to changes in the building codes but the most critical is indoor air quality – both with regard to building air tightness requirements and materials development.

This could be offset or decreased in importance if product transparency actually drives clear and better materials over time.

All that product transparency is showing us right now is just how bad the things we are using really are.  But that’s a starting point.  When we start looking at the transparency documents that are available in the market today, we realize that the things we are using are emitting a lot of materials and are not what we would start with in an ideal world.

One thing that transparency does drive is organic improvement in our building materials to be healthier for us.  But until that occurs, we have to take the information available to us which is so much more than we’ve ever had before and begin to address the issues.

The challenge has clearly been put before us.  Until materials improve, we have to pay very close attention to the materials we are currently using and how they work into our indoor air quality goals because the benefit of haphazard or uncontrolled natural ventilation has been removed from our future.

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.

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.

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.
