INFORM Magazine Article: Specifying American-Made Building Products

Builders experienced shocks to their supply chain in early 2020 from COVID-19. The Associated General Contractors of America (AGC) reported in April 2020, 45% of contractors experienced shipping delays or supply chain disruptions due to COVID-19 as manufacturing facilities and ports closed overseas.

The building product industry is highly globalized and contractors are often reliant on imports. According to Richard Branch, chief economist at Dodge Data & Analytics, 30% of all building products used in the U.S. are from China, with another 20% sourced from Mexico and Canada. Smaller, lower-cost, and more standardized products are typically manufactured outside the U.S. The products most likely to be sourced overseas include hardware, electrical materials, lighting fixtures and bulbs, plumbing, and fire protection systems. Domestic manufacturers also rely on raw materials and components from overseas to build their finished products.

As the COVID-19 pandemic continues these impacts are expected to remain, leading to higher prices and supply chain bottlenecks for contractors, especially as construction rates return to normal. As a result, contractors and manufacturers are seeking ways to build a more resilient supply chain.

For many common building materials, it is possible for builders to find a domestically made alternative. Contractors can ensure their projects are flexible enough to avoid tariff risks by specifying and purchasing American-made building products. Always specifying at least one product made close to home makes sure your project’s contractors have options.

BuildingClean.org Adds Building Enclosure Products to American-Made Building Product Database

BuildingClean.org, an online tool that links the energy, housing, and health sectors together, today announced the addition of building enclosure products to its American-made building product database.

“We are excited to expand our database to include building enclosure products,” said BlueGreen Alliance Foundation National Program Manager Dana Saylor. “These products—from drywall to brick—are crucial to the construction of every building. Using American-made building products helps guarantee a reliable supply chain, it also sustains more than 4,600 building product manufacturing facilities across the United States. Energy-efficient products and recycled building materials alone support more than 320,000 American manufacturing jobs.”

The new building enclosure section of the database includes 1,985 production sites making products from grout to masonry, wood framing, sheathing, waterproofing materials, and more.

For an exterior wall, the building enclosure typically includes all building components from the interior surface of the wall outward to the exterior surface of the building, including windows and doors. Similarly, for a roof the enclosure typically includes all building components from the interior surface of the ceiling outward to the roof membrane, asphalt roofing, or roof shingles. For foundations, building components extend from the interior surface of the foundation wall and floor/concrete slab outward to the foundation insulation and soil. BuildingClean.org has separate sectors on roofing, insulation, joint sealants, and windows, doors and skylights that together with the building enclosure listings represent all the U.S. manufacturing in this important building concept.

Building Clean is an initiative of the BlueGreen Alliance Foundation and the Building Clean American-made products database also includes appliances, lighting, plumbing, roofing, sealants, HVAC, and water filtration products. The database is easily searchable by manufacturing location, material, product type, or CSI-code to  find products.

BuildingClean.org Report Finds “Buy American” Policies Would Dramatically Boost Manufacturing Jobs Making Energy-Efficient Products

The report, entitled Manufacturing Efficiency: How Buy America Policy Can Boost Jobs Manufacturing Energy-Efficient Products, compared the manufacturing job creation potential of strengthening all retrofits to full deep retrofits, increasing the retrofit rate, and implementing Buy American policies.

“Increasing the retrofit rate, strengthening retrofits, and enacting Buy American policies will deliver more than 170,000 manufacturing jobs across the nation, while driving down emissions and securing a more sustainable future for the nation,” said Jason Walsh, President of the BlueGreen Alliance Foundation. “This report shows the tremendous opportunity in making the products we need to make our homes and buildings more energy efficient at a time when America’s manufacturing sector is in need of revitalization and millions of Americans have applied for unemployment during the ongoing pandemic.”

The study found that increasing demand for American-made energy-efficient housing products through Buy American policies and deep retrofits will boost job creation in manufacturing, with appliance and HVAC manufacturing showing the most growth. At the current estimated retrofit rate of 2%, just strengthening retrofits to full deep retrofits would support 132,000 manufacturing jobs. Adding a Buy American policy to a deep retrofit rate of 2% would create another 20,000 jobs. Finally, the report explored the impact of increasing the deep retrofit rate to 4% while also enacting a Buy American policy. Under this scenario more than 170,000 additional jobs would be created.

“Our nation is long overdue for a massive infrastructure investment, including funds to modernize our existing buildings,” said United Steelworkers (USW) International President Tom Conway. “Using American-made materials as we upgrade our homes and businesses will not only ensure that they are safer and more efficient, but will also create good, union manufacturing jobs, helping rebuild our battered economy and laying the foundation for a brighter future for all.”

With the right policies in place, energy efficiency could be a driver of significant growth of manufacturing jobs in the United States. Deep retrofits go beyond basic weatherization and feature exterior continuous insulation; energy-efficient appliances; heating, ventilation, and air conditioning (HVAC); and windows.

“The benefits of enacting the actions outlined in Manufacturing Efficiency are undeniable,” Walsh said. “The creation of manufacturing jobs in communities across the nation will help our nation heal from the devastating economic impacts of the ongoing COVID-19 pandemic. Stopping energy waste will strengthen our fight against climate change. And, ramping up residential deep retrofits—especially in affordable housing—will make the buildings we live and work in healthier and safer.”

Home Radon Levels Go From Low to Dangerous within 150 Feet

By Michael Miranda, LEED AP, HERS Rater, Building Clean Outreach Manager

A HIDDEN PROBLEM

Radon is a naturally occurring radioactive gas that can cause lung cancer. Radon is released as radioactive metals uranium, thorium, and radium break down in rocks, soil, and groundwater. It enters homes primarily through openings in the basement or slab. You can’t see or smell radon. The only way to know your level of exposure is to test for it.

After reviewing state historical testing data for radon levels in the Rochester area, Building Clean suggested that Flower City Habitat for Humanity—a builder of high-quality and healthy affordable housing—perform radon testing on its latest homes. Flower City Habitat for Humanity conducted radon testing on four new homes built within 300 feet of each other.

TESTING FINDS A SURPRISING RESULT 

Despite the four homes having been built the same way—by the same builder and during the same time period—the tests found that radon levels varied significantly within just 150 feet. The results found low levels of radon on one side of the street but dangerous levels on the other side. 

Radon testing in three of the homes on the same side of the street found levels of 1.0 pCi/L or less. Testing in the fourth home, which is across the street from the other three homes, found a radon level of 8.12 pCi/L. To put these numbers in context, the U.S. Environmental Protection Agency (EPA) considers it necessary to remediate a home if the radon level is 4 pCi/L or higher, and urges remediation if the level is between 2 and 4 pCi/L. Internationally, the World Health Organization recommends action if radon levels are above 2.7 pCi/L.

Luckily Flower City Habitat has a valued volunteer in Jim Bradley, who has been working closely with the Building Clean team and has experience dealing with radon.

To test the Flower City Habitat homes, Jim used his own electronic radon monitor. Testing was performed in the basements of the homes while the homes were in the final phases of construction with finishes and appliances being installed. The electronic radon monitor has a screen that constantly displays the long-term and short-term radon level, updated daily and hourly respectively.

The electronic radon monitor results were confirmed with a traditional short-term radon test kit that is mailed to a lab for analysis. The short-term radon test kit revealed that sealing the sump pump cover produced a small reduction in radon levels.

FIXING THE PROBLEM

The EPA classifies every U.S. county into one of three radon zones—Zone 1, 2, or 3—based on predicted average indoor radon levels. The four homes that were tested are in a Radon Zone 2—counties with predicted average indoor radon levels from 2 to 4 pCi/L. During its Rochester work, Building Clean found New York State Department of Health data showing that 10% of homes with basements in Rochester have radon levels greater than 4 pCi/L.

Zone 1 counties are expected to have the highest radon levels, with predicted average indoor levels greater than 4 pCi/L. Zone 3 counties are expected to have the lowest radon levels with predicted average indoor levels less than 2 pCi/L.

The EPA stresses that no matter where you live, and no matter the radon zone, the best practice is to test your home for radon. In multifamily buildings, the EPA and the Surgeon General recommend testing all units below the third floor for radon.

After the test findings, the next step was to install a pipe from the sealed sump pump cover to the outdoors, so that radon under the foundation has an easy path out before having a chance to enter the house. Installing the pipe is called “passive radon ventilation,” but that is not always enough and a fan (powered ventilation) is sometimes needed to pull the radon out. Follow-up electronic radon monitor results showed no impact from passive ventilation connected to the sump pump cover, and powered fan ventilation would be needed.

HOW AND WHY TO TEST YOUR HOME

With energy efficiency and healthy homes being more valued, closing openings that let in pests and pollution and let out expensive conditioned air also has the potential to change home radon levels. Home improvement work such as installing a sump pump, adding a bath fan in the basement, air-sealing, weatherization, and more may allow more radon in or stop it from leaving. Re-testing your home’s radon levels after making these types of improvements is highly recommended. Because radon levels tend to vary from day to day and season to season, a short-term test (2 to 90 days) is less likely than a long-term test (more than 90 days) to tell you your year-round average radon level.

There are two types of do-it-yourself radon test methods, a traditional radon test kit that is mailed to a lab for analysis and an electronic radon monitor that displays radon results on a screen or a smart-phone app.

Both methods can be used to perform a short-term test (2 to 90 days) and a long-term test (more than 90 days). Before buying a mail-in short-term radon test kit, be sure to confirm how long you can test as some only test for 2 to 7 days.

Builders might consider investing in an electronic radon monitor, like the one Flower City Habitat for Humanity used, so they can monitor radon levels within multiple homes and buildings. According to the EPA, nearly 1 out of every 15 homes in the United States is likely to have elevated radon levels. Radon is estimated to cause about 21,000 deaths from lung cancer each year.

What’s In Your Water?

The drinking water systems of approximately 19 million people have been contaminated by a class of chemicals known as PFAS, according to a recent report by the Environmental Working Group and Northeastern University. The study found 610 contaminated sites in 43 states.

PFAS is short for per-or polyfluoroalkyl substances and what makes them great for consumer and building products are their properties that repel water and stains. However, the same properties that make them popular also make them dangerous because they do not break down easily and are not water soluble—meaning they stick around in the environment. There are a number of pathways for human exposure, one of which being the water that we drink. PFAS get into our drinking water through industrial waste from sites where they are created, disposed of, or used. Exposure through water is especially prevalent near military bases, firefighting training stations, and industrial facilities.

However, you do not need to live near one of these sites to have been exposed to PFAS. Because of their persistence in the environment, PFAS are found in drinking water systems and wells across the United States.

The exact health effects of PFAS are not totally understood yet. There are more than 3,000 chemicals in the PFAS family and tracing back health effects is difficult. Two of the worst PFAS chemicals—PFOA and PFOS—have been phased out because studies linked exposure to:

  • Testicular, kidney, liver, and pancreatic cancers;
  • Weakened childhood immunity;
  • Low birth weight;
  • Endocrine disruption;
  • Increased cholesterol; and
  • Weight gain in children.

These two PFAS chemicals are no longer in use in the United States but evidence suggests that the chemicals developed to replace them may be just as harmful.

The persistence of PFAS in the environment makes it difficult, but not impossible, to protect yourself. One step you can take is installing a water filtration system to protect you and your family. Check out BuildingClean.org for a FREE database where you can find an American-made water filtration system that works for you.

Latest Project from A Tiny Home for Good Applauded by Building Clean

The IUE-CWA Housing Corp. funded the build and also supported Building Clean as a product selection consultant. Building Clean works to find healthier, locally sourced, and more energy-efficient products at an affordable price so that the benefits of sustainable building practices are shared by everyone, regardless of the income.“We congratulate A Tiny Home for Good on completing its latest project in its quest to end homelessness,” said Building Clean National Program Manager Dana Parker. “At this afternoon’s ribbon cutting ceremony, the new renters will not only find a home, but one that is healthier, more energy efficient, and built with locally or U.S.-made products as much as possible.

Building Clean is an online database that allows residents, architects, workers, non-profits, and others to find local, healthy energy-efficient building products for their projects.

“Building Clean helps to put resident well being on an equal footing with lower utility bills,” said Parker. “We also help grow the regional economy and manufacturing sector by sourcing products as close as possible to the construction site. Building a stronger local economy means A Tiny Home for Good not only helps reduce homelessness but does it while supporting Syracuse’s tax base and employment.”

“They may be tiny homes but they have a huge impact throughout the Syracuse community and we’re proud to help them accomplish their great work,” added Parker.

Literally Building Green

Researchers at Aarhus University in Denmark used satellite data to go back over 20 years to approximate proximity to green space when study participants were 10 years old or younger. That data was then linked with the Danish Psychiatric Central Research Register, which documents psychiatric facilities admissions.

The results showed that the more a person was exposed to green space before the age of 10, the less likely they were to develop mental health issues, such as mood and stress-related disorders, later in life.  The finding holds true even when controlling for external factors such as socioeconomic status, family history, urbanization, and parents‘ age.

The paper is not the first to show the benefits nature has on human health and well-being. Access to nature while indoors makes people happier and more productive. Elements such as green walls, indoor plants, and even views of nature outdoors are shown to increase worker productivity by 6 percent, and 40 percent of American workers agree that live greenery inside made them feel more relaxed. A study in Michigan found that views of trees from cafeteria and classroom windows were positively associated with higher standardized test scores, graduation rates, and college attendance.

Green space also is linked to better physical health, with one study finding that the likelihood of obesity was around 40 percent lower for those living in residential areas with lots of access to nature.

The benefits to integrating green spaces into architectural designs is clear. We need to literally start building green.

Building Clean: Buy Local, Buy Healthy

BuildingClean.org is a free tool that can help both building professionals and consumers discover what type of building products contain dangerous chemicals and how to find healthier alternatives.

What homes are built of impacts us in numerous ways. For example, studies have repeatedly linked residential chemical emissions with respiratory ailments such as asthma. Nearly 40 percent of medically diagnosed asthma is triggered by residential sources, such as volatile organic compounds (VOCs), which can be found in paints or flame retardants in insulation.

And asthma is just the beginning. Chemicals found in building products also can can cause cancer, lead to reproductive issues, and disrupt hormones critical to growth, among many other health impacts. The Harmful Chemicals section of the Building Clean website outlines hazards by product sector, and helps you evaluate products to make healthier choices.

Building things the right way with cleaner, healthier products can have a huge impact. One study found that when homes are built to eliminate pollutants—including using building products that have cut out harmful chemicals—asthmatic children had 63 percent more symptom-free days.

The key to making good decisions is good information. Knowing what is in the product is half the battle. Ingredient transparency has been an ongoing struggle. Voluntary disclosures and health certifications are one way that manufacturers can provide these details.

Building Clean explains the certifications and transparency documents in use in the current building product market and hosts a consolidated certified product search that allows you to find in one location products that have any of the major certifications and transparency listings. It also adds in helpful search terms. For example, you can search flooring or insulation by material type or water filtration devices by location in the home. The consolidated certification listings cover the following sectors: flooring, insulation, paint and wallcoverings, sealants, water filtration systems, and windows, doors, and skylights.

To better understand how toxic chemicals in products can impact the health of installers and residents, Building Clean provides a chemical library that has one-page, easy-to-read summaries about short-term effects of exposure—such as skin, eye, or respiratory irritation—as well as long-term effects.

The health of our homes is critical to the health of our communities. Building Clean gives us the information needed to motivate and direct us on how to improve both.

Long Live Your Community: Building an Enduring Resilience Takes More Than Stronger Buildings

The following blog was written by Caila Prendergast, a Program Associate working on the Building Clean Program.

Estimated property damage from natural disaster from 2017-2018 was nearly $400 billion, but that is the least of the storms’ impacts. During Hurricane Harvey, damaged oil refinery equipment led to an estimated one million pounds of chemicals such as benzene and sulfur dioxide being released into the air, rates far higher than deemed acceptable. Flood waters were permeated with sewage and hazardous chemicals from damaged chemical manufacturing plants. In California, the thick smoke full of dangerous substances was released as homes and other buildings burned.

As the frequency and severity of natural disasters impact people and communities in a larger way than ever before, resiliency in the built environment is being recognized as a crucial element in mitigating these impacts. Especially since those who lose the most are often the ones who had the least to begin with.

Substandard housing only makes destruction more likely, adds to the hazardous substances entering the air and water, and increases the threat of personal injury. In low-income communities, whose pre-existing inequality compounds in the aftermath of a natural disaster, an already fragile existence falls apart as buildings are condemned rather than repaired and residents face homelessness rather than hope for a quick recovery.

Building resilience involves building a home that is protected from extreme weather events, able to adapt to changing circumstances, and equipped with backup equipment in the case of failure. This includes improving envelope efficiency, flood proofing, installing backup power, and ensuring potable water. It also means using healthier building materials to minimize the danger of chemical releases from buildings during a natural disaster.

But building resilience is not just a reaction to short term needs revolving around housing. A roadmap for building resilience in multifamily housing from Enterprise Green Communities checks off the steps to take to prepare the building. But the advice tackles more than just physical structures.

Community resilience is another important aspect and involves strengthening neighborhood ties and organizing in the face of disaster both before and after it strikes.

“Acting for long-term resilience within the timeframe of immediate recovery will allow the region to address the many forms of recovery—from economic, to structural, to environmental and physical,” notes a report examining the aftermath of Harvey in Houston. “Within this action, though, we should empower communities to shape the process for themselves, invest in mitigation and resilience in all areas of the region, not just those hit by Harvey, and accept that challenges preventing resilience are different in every community.”
