Energy Savings Go Through the Roof!

Posted By PIMA

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.

Canada to Address Building Code Gap for Existing Buildings

Posted By PIMA

The Canadian Commission on Building and Fire Codes has issued recommendations to address “the absence of clear code requirements for existing buildings.” The report outlines an approach to constructing a regulatory framework for today’s building stock to address five objectives, including improved energy efficiency. Canada has invited interested stakeholders to provide input on the report through a brief online survey by August 30, 2019. PIMA plans to submit comments that highlight the United States’ experience with the existing building provisions of the IECC and respond to the report’s concerns of building fire safety.

Energy Conservation Lives!

Posted By PIMA

A recent Trump Administration document “encourages communities to adopt and enforce up-to-date building codes.” This important policy recommendation, contained in the Federal Emergency Management Administration (FEMA)’s National Mitigation Investment Strategy (NMIS), is expected to further catalyze code adoption and pave the way toward enforcement of these critical building standards.

The NMIS Recommendation 3.1 further states:
“Building codes regulate the design, construction, and occupancy of buildings and structures by providing minimum requirements to safeguard public safety, health and general welfare. Architects, engineers, builders, and regulators should use the latest building codes for the most up-to-date requirements for structural integrity, mechanical integrity, fire prevention and energy conservation. Using up-to-date building codes helps communities survive, remain resilient, and continue to provide essential services after a disaster occurs.”

This recommendation, combined with increased code adoption at the local level will be a powerful market signal. Further information and an explanation of the document is available here.

Insulation Fly-In: Building Relationships for Better Buildings

Posted By PIMA

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 PIMA

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 Fire Performance

Posted By  PIMA

All construction materials, including insulation products like polyiso, must provide a suitable margin of fire safety. Polyiso insulation products are tested per material-specific tests as well as part of full assemblies that test fire performance as constructed. Importantly, polyiso possesses a high level of inherent fire resistance when compared to other insulations due to its unique structure of strong chemical bonds. These bonds result in improved high temperature resistance (up to 390 degrees F – more than twice the temperature resistance of some other building insulation products), which in turn leads to enhanced fire resistance. In addition, polyiso does not melt or drip when exposed to flame. The product forms a protective surface char that enhances its fire resistance in terms of reduced flame spread and the potential to contribute to flashover.
