Energy Savings Go Through the Roof!

Posted By Administration, Monday, November 11, 2019
Updated: Monday, November 11, 2019
When it’s time to replace a roof, most owners choose roofing materials based on performance qualities like longevity and weather resistance. But a well-designed roof can also shine in another performance area: energy efficiency.

Energy efficiency is important to many owners with concerns ranging from climate impacts like building carbon footprints to the costs and reliability of energy resources. Since approximately 25 percent of heat loss in an uninsulated building occurs through the roof, choosing materials that add insulative power can add significant energy savings. For commercial and low-slope roof applications, adding layers of rigid foam insulation to the roofing system can deliver exceptional R-value without a lot of bulk.

An article last month from the Energy News Network details initiatives in Warren, Minnesota and Arnsberg, Germany to use thermal imaging in evaluating building heat loss to help owners determine the best energy efficiency opportunities.

The program was conceived after municipal leaders from Warren and Arnsberg met through the Climate-Smart Municipalities program sponsored by the University of Minnesota’s Institute on the Environment which paired five cities in Minnesota with similar cities in Germany. Arnsberg had been using remote-piloted aircraft to collect thermal images of building heat loss. Leaders in Warren decided to try using drones to get more detailed information.

Piggybacking off each other’s ideas, the two cities are innovating the practical applications of these thermal images in directing energy efficiency efforts to the places that will have the greatest impact. Their research provides further evidence that reroofing with energy-efficient materials can decrease building heat loss and lead to reduced energy consumption.

New Wisconsin High School Uses Polyiso CI System

Posted By Nathan Pobre, Tuesday, June 18, 2019
Updated: Tuesday, June 18, 2019

Voters in Verona, WI passed a referendum in 2017 to build a brand-new high school. Once the new school is ready, the existing campus will be renovated to become a middle school and then the existing middle school will be converted for use as a new elementary school. The ambitious plan was undertaken to invest in long-term solutions for the school district’s needs and as a result care was taken in designing a new high school that would perform well over the long haul.

Construction is now underway on the new high school, designed in a collaborative process with staff, students, and project team members to provide an adaptable and vibrant modern learning environment in a safe place to support the physical and emotional wellbeing of students. Responsive to the natural environment, the new high school maximizes views and daylighting and offers outdoor learning spaces. At the heart of the building is a three-story atrium to encourage socialization and collaboration. The 585,000-square-foot building is scheduled for completion in preparation for the 2020-2021 school year.

To keep the building comfortable throughout the changing seasons and to minimize its energy needs, the design team selected products for the walls that would provide maximum insulation with minimal maintenance. More than 100,000 square feet of Johns Manville 2 ½ inch foil-faced Polyiso CI boards are being used on the project. They offer a reflective foil facer on one side and a non-reflective facer on the other to provide exceptional heat, moisture and air control. When installed correctly the Polyiso CI system provides a layer of continuous insulation that eliminates the thermal bridges that cause heat loss.

Insulation Fly-In: Building Relationships for Better Buildings

Posted By Nathan Pobre, Thursday, May 30, 2019
Updated: Thursday, May 30, 2019

In this age of instant connectivity, virtual encounters allow communication and cooperation with unprecedented speed and ease. But there’s something about a face-to-face meeting that really helps people reach common ground. In May, 110 contractors, manufacturers, and suppliers from the insulation industry representing the majority of states met on Capitol Hill with lawmakers to discuss issues and ideas for harnessing the resources of the insulation industry to tackle some of our country’s most pressing problems. And they were serious about building those face-to-face relationships—and packed in 101 meetings on Capitol Hill, 23 of them with members of Congress.

With the constant stream of news stories highlighting the human costs and economic consequences of a changing environment, momentum is growing behind solutions that can address these environmental challenges in ways that strengthen U.S. economic productivity and competitiveness. To that end, PIMA members are working to build enthusiasm for federal action on policies that optimize the energy efficiency of new and existing buildings. Raising standards for new residential, commercial, and industrial buildings and retrofitting older ones can lead to long-term savings through better building performance.

Increasing the energy efficiency of our buildings is a practical way to help the environment, create jobs, and save money. Boosting energy efficiency alone can provide 40% of the necessary greenhouse gas emissions reductions to meet global targets and the work to implement these standards will lead to jobs in manufacturing, distribution, and installation. These improvements will save consumers billions of dollars in energy costs annually – money that can be invested back into the U.S. economy.

But these policies would do more than save energy; they’d also provide buildings and the people who use them with added protection from severe weather events. In 2017 alone, there were $317 billion in losses from US natural disasters, jump-starting discussions on creating more resilient buildings and communities. Optimizing insulation for an energy efficient building envelope improves performance post-disaster or during prolonged events like heat waves or extreme cold. And the investment would pay off – it’s estimated that designing buildings to the 2018 I-Codes would deliver a national benefit of $11 for every $1 invested.  

Some legislative tools to promote these improvements include:

  • Strengthening oversight of new rules for disaster preparedness and response.
  • Supporting investments in building science research.
  • Recognizing buildings as infrastructure, including critical structures such as hospitals and schools.

Improving the energy efficiency and resilience of our built environment is a proactive approach to reduce greenhouse gas emissions while boosting economic growth, improving energy security, and advancing U.S. global competitiveness. PIMA members are working together to promote policies that support these goals through events like Insulation Industry National Policy Conference.

The Overarching Impact of the Insulation Industry

Posted By Nathan Pobre, Wednesday, May 29, 2019
Updated: Wednesday, May 29, 2019
Insulation can be found in buildings, refrigeration and a multitude of other end use products, and is used for floatation and transportation. From an environmental standpoint, when insulation products such as Polyiso are used in building and construction, the purpose of the insulation is to stop the flow of air (hot or cold) through the exterior walls and roofs of a building. Reducing the air transfer reduces the amount of energy required to regulate a building’s heating and cooling system. As a result, the insulation has a direct impact on the cost and use of energy to run that building.

Beyond its sustainability and environmental attributes, a new report, “The Contributions Insulation to the U.S. Economy in 2018,” produced by the American Chemistry Council (ACC), shows that the insulation industry contributes significantly to the U.S. economy. In fact, the industry generates more than 550,000 jobs and $33 billion a year in payrolls. For extended details on the economic contributions, insulation industry segments, and more view the full study here.

Polyiso Roof & Wall Insulation: Helping New International Concourse at LAX Meet the Codes

Posted By Nathan Pobre, Friday, May 3, 2019
Updated: Friday, May 3, 2019
The ongoing overhaul of the Los Angeles International Airport (LAX), the nation’s third busiest airport, is a complex web of projects. One of its major components is the new Midfield Satellite Concourse (MSC) North, a five-level, 750,000 square-foot expansion accessible via a spacious 1,200 ft. long tunnel corridor with moving walkways from the Tom Bradley terminal. As with any major construction undertaking, the project is designed to meet a wide array of building codes, including the California Green Building Standards Code (CALGreen) mandatory sustainability related requirements, and its Tier 1 voluntary sustainability measures that each jurisdiction has the option to enforce.  

CALGreen is the first-in-the-nation mandatory state green building standards code. Developed in 2007, it targets the reduction of Greenhouse Gas (GHG) from buildings, while promoting environmentally responsible, cost-effective, healthier places to live and work. In order for the new MSC to meet the exacting CALGreen Tier 1 specifications, the thermal insulation used in the project had to meet key requirements that measured volatile organic compounds (VOC) emissions. Designers worked to find a continuous insulation capable of reaching those goals and providing the durability and protection required for the high-demand building conditions.

Additionally, since the new concourse is designed to complement the ocean wave theme of the airport, the architects envisaged a stunning curvilinear roof. This unique design element demanded some additional roof and wall configuration requirements. The team needed insulation materials that could be custom fit to meet custom curvature and design needs.

The design and construction team began searching for an insulation solution that would meet or exceed all code and environmental requirements and provide the flexibility and ease of installation that would make it a viable option for such a large project. Atlas polyiso roof and wall insulation products were continually recommended by industry experts due to their low VOC emissions and optimal performance. Atlas polyiso roof and wall insulation products have passed the vigorous testing requirements for GREENGUARD Gold certification.

The size and scale of the project is significant. More than 500,000 square feet of polyiso are required on the roof and more than 215,000 square feet will be used in the walls to ensure top building performance by providing a high R-value, durability and water resistive barrier attributes available.
