HBN tested 94 commercially available paint products for the presence of harmful per- and polyfluoroalkyl substances (PFAS), called “forever chemicals”. Approximately 50% of ‌paints tested positive for fluorine, a marker of PFAS. Review the details of our findings and the recommended actions you can take.

HBN and Perkins&Will have released a second report aimed at transforming the way project teams select sustainable, low-carbon products. Building on the first report titled “Embodied Carbon and Material Health in Gypsum Drywall and Flooring,” a second report investigating the intersection of carbon and material health is titled “Embodied Carbon and Material Health in Insulation”.

Insulation is a unique product category that can help reduce a building’s operational carbon emissions by optimizing performance, lowering the energy required for heating and cooling. Those same materials can also negatively impact the environment by releasing greenhouse gasses throughout their life cycle. Insulation can also contain toxic chemicals that migrate into interior spaces. This report provides guidance for designers and architects to choose the best materials that takes materials health and embodied carbon into consideration.

Key Highlights from the reports include:

  • Optimized Products for Material Health and Embodied Carbon: The reports show that products improving material health and embodied carbon are available across all the examined product categories: flooring, gypsum drywall, and insulation.
  • Screening for Optimized Product Types: Professionals are advised to first screen for optimized product types before selecting specific products. This approach helps teams capitalize on the fact that the biggest improvements can be made by selecting different product types within a product category.
  • Navigating Potential Contradictions: Acknowledging that embodied carbon and material health considerations are sometimes contradictory, the reports emphasize the importance of reviewing the provided guidance to make informed decisions.

The reports represent a significant step forward in sustainable design practices, offering actionable insights that empower professionals to make environmentally conscious choices without compromising on carbon or health priorities.

Pediatric physician, Dr. Nicholas Newman, discusses his experience treating patients impacted by PFAS in this video by the Great Lakes Center for Reproductive and Children’s Environmental Health.

This comprehensive guide, designed for architects, engineers, and contractors, provides expert insights, academic research, and practical advice on various aspects of piping systems, including material properties, safety considerations, health risks, environmental impacts, and emerging trends.

A study investigated the presence of per- and polyfluoroalkyl substances (PFAS) in dust from buildings with “healthier” materials, finding lower PFAS contamination levels compared to conventional buildings, highlighting the importance of using chemical class-based methods for evaluating PFAS exposure.

In this study several commercial paints were analyzed for volatile and nonvolatile per- and polyfluoroalkyl substances (PFAS), finding that paints could be potential sources of human exposure to PFAS, with one paint exceeding the reference dose for children and adults.

Project teams want buildings that are healthy for people and the planet. Two sometimes competing criteria to evaluate the sustainability of building products are embodied carbon and material health.

For this case study, Perkins&Will partnered with Healthy Building Network to identify key drivers of embodied carbon and material health by looking at specific examples of product categories frequently specified in building projects. Using flooring and drywall as examples, this study identifies some examples of where paths toward low embodied carbon and safer materials align and where they conflict.

The goal of this case study is to translate the learning from embodied carbon assessment tools and material health assessment tools into actionable guidance for manufacturers, project teams, and green building programs that will allow them to optimize decisions and promote and select healthier, low-carbon products that advance a circular economy.

We have been picking on plastics a lot recently (see articles: Addressing the Plastic Crisis: Why Vinyl Has to Go and The Illusion of Plastic Recycling: Neither Just Nor Circular). This is because we believe that typically the best way to avoid hazardous chemicals is to avoid plastic altogether. With this said, we recognize plastics in buildings are currently ubiquitous (see article: Our Plastic Buildings: A New Driver of Fossil Fuel Demand).

So, let’s consider what would need to happen for plastic building products to be considered truly sustainable. Can the plastics industry do better? What are the key opportunities today to do so, and what global policy tools could promote these opportunities? These are among the key questions HBN explored in the development of a pair of case studies for the international Organization for Economic Co-operation and Development (OECD) as part of the Inter-Organization Programme for the Sound Management of Chemicals (IOMC).

Before we jump into the case study findings, first, let’s define plastics. For the purposes of this article, we define plastics to be any polymeric material, fossil fuel based or bio-based. The case studies focused on durable plastic goods, using building materials as an example.

The case studies explored both plastic flooring and plastic insulation with the goal of increasing awareness of environmental and human health impacts of plastic product production at each stage of the lifecycle and proposing policy interventions that can help move the industry toward more sustainable plastics products in general.

What would be defined as a sustainable plastic?

In the report, we created a framework for evaluating what a truly sustainable plastic product would look like. These goals are lofty, and currently no existing plastic building materials meet these goals. However, they provide a pathway towards truly sustainable products.

To be considered a sustainable plastic, a product would have to enhance human and environmental health and safety across the entire product life cycle. It would have to be managed within a sustainable materials management system, and would have to meet the following goals: 

  • Must be inherently low hazard. 
    • Hazardous substances are eliminated.
    • Transparency in terms of content and emissions exists at every step of the supply chain.
    • Full hazard assessments are available on all chemicals.
  • Must have a confirmed commercial afterlife.
    • Products designed for durability, reclamation, reuse, and recycling.
    • Infrastructure exists to support reclamation, reuse, and recycling.
    • Materials can undergo multiple cycles of recycling.
  • Must generate no waste.
    • Manufacturing scrap is eliminated at every step of the production process.
    • Scrap from installation is eliminated.
  • Must use rapidly renewable resources or waste-derived materials.

Trade-offs examples

The case study explores trade-offs that exist between different material choices.

For a flooring example, a product that is designed to use adhesive to install is typically thinner than one that uses a click tile system to install. These thinner products use less material per square foot and therefore have less chemical impacts associated with manufacturing and less waste at the end of life. However, adhesives may add hazardous substances to the product installation stage. By moving from a click tile product to a glue down product, chemical exposure burdens shift from manufacturing and end of life to the installation stage and use phase. 

For an insulation example, a product that is designed to chemically react at the build site, such as spray polyurethane foam (SPF), can allow the insulation to form an air-sealed custom fit. However, SPF is not recyclable, and adherence of that insulation to surrounding materials may also make those materials more difficult to reclaim or recycle. Moving from XPS, EPS or polyiso to SPF may reduce the ability of other surrounding materials to “have a commercial afterlife” in the pursuit of an added performance feature.

Building awareness around these trade-offs enables stakeholders to make informed choices.

Back to reality

Now, back to reality after crafting the characteristics of a theoretical sustainable plastic. The bottom line is that there are no sustainable plastics that exist today, and we are a long way off from that day. Today, project teams need to prioritize which sustainability goals are most important and how to deal with real and significant gaps in understanding and/or data.

The case studies compared only product types made of plastic, but in reality, project teams have a wider variety of materials to choose from in any given product category. HBN’s Product Guidance considers the most commonly used product types within a product category and ranks those product types relative to one another from a chemical hazard perspective. Product types made of plant-based materials or minerals tend to rank higher than plastic products. You can apply the same sustainability goals proposed in this article to non-plastic products.

In project design, the biggest leaps towards more sustainable products from a chemicals perspective often requires consideration of vastly different materials versus making incremental improvements in chemistry for a particular product type. For example, this could mean moving from vinyl to linoleum flooring versus attempting to select the least bad vinyl option.

Check out the full flooring and insulation case studies for examples of how to use these goals to consider and choose the variety of plastic product types you will inevitably be specifying for your next project. Alternatively, challenge yourself to skip the plastics whenever possible. Even selecting one non-plastic product is cause for celebration. Make the swap!

This Women’s History Month, we’re celebrating an incredible leader in the green chemistry and healthy materials space: our very own Teresa McGrath! Teresa is Habitable’s Chief Research Officer, leading our research strategies.

Prior to working at Habitable, Teresa led the Chemical Management Program for Sherwin-Williams, the largest paints and coatings company in the world, where she focused on hazards reduction and transparency and assisted business units in meeting sustainability and green chemistry goals. She also spent nine years as the Senior Managing Toxicologist at NSF International’s Green Chemistry Programs, and two years at the Environmental Protection Agency in the Design for the Environment (DfE) Branch of the Office of Pollution Prevention and Toxics (OPPT).

We caught up with Teresa to learn why she’s a champion for safer chemicals and healthier products and to get her perspective on the industry today.

HABITABLE:
What got you interested in working in sustainable products and clean chemistry?

TERESA MCGRATH:
It all starts with my family. Specifically my father – who would never identify as an environmentalist – but through his actions taught me to care for those who are most vulnerable and to take care of our planet. For example, more than once I witnessed my dad giving CPR to an injured animal that one of our dogs had mangled. In grade school I disgusted my friends by pulling carrots out of a peanut butter and jelly coated baggie my father had reused (this was before reusable bags were a thing!).  

In college I did a research project on how to remove pesticides from drinking water using a biocatalytic filter method. It took me until the end of the project to ask myself “Wait, why is this pollution in our drinking water to begin with? Why are we using chemistry in such an inefficient, clumsy way?” After a little digging I stumbled on the Twelve Principles of Green Chemistry, authored by Dr. Paul Anastas and Dr. John Warner. These principles are centered around using chemistry to prevent pollution rather than create it, to make efficient use of resources down to every atom, to avoid waste. This was an inspiring moment for me.

I decided to pursue a graduate degree in chemistry that focused on Green Chemistry. At the time the only graduate program focused entirely on “Clean Chemical Technology” was in the U.K. at University of York. Off to England I went, and I have worked in the field of Green Chemistry for my entire career. 

H:
What has surprised you the most about working in this field?

TM:
I have worked in government, NGOs, and industry. I think what is surprising is how much these stakeholders have in common and how most people want the same things when it comes to human health and the environment. Most people want (to make, use, or buy) safer products that work well and they can afford. It is this alignment that we can all use to make progress.

The most exciting projects in my work experience were those that harnessed input from different stakeholders with different perspectives. For example, in 2017 Valspar invited NGOs and academics who fought against the use of the endocrine-disrupting chemical bisphenol A (BPA) to help them design and test alternatives to BPA for use in food packaging. 

We can all learn from each other, and these moments of collaboration are critical to enable market changes toward products that are safer for human health and the environment. 

H:
Who has inspired you along your journey?

TM:
In addition to Dr. Anastas and Dr. Warner, I am grateful to Dr. Lauren Heine, who I met at a Gordon Green Chemistry conference when I was in graduate school and has been a friend and mentor to me ever since. Dr. Heine is a leader in the field of green chemistry, green engineering, and sustainable business practices.

I first met Lauren when she was the Director of Applied Science at Green Blue Institute, where she developed the CleanGredients database in partnership with the U.S. Environmental Protection Agency (EPA) to help cleaning product manufacturers find safer alternatives. At Clean Production Action, she co-authored and led the development of the GreenScreen for Safer Chemicals, a method for comparative chemical hazard assessment. She has also worked as Director of Science and Data Integrity at ChemFORWARD, where she co-created a harmonized chemical hazard assessment methodology that will not helps people avoid chemicals of concern, but also identify safer alternatives. She serves on various advisory boards and committees all over the world to share with the rest of the world a bit of the brilliance whenever she can. 

Lauren taught me that collaboration is one of the most important tools to inspire change. She has an unique ability to build connections and relationships with every project she is involved with. I aspire to approach my work with this same focus.

I also credit Lauren with helping me land my very first job out of graduate school at the EPA despite the fact that I handed her a printed resume on scented paper (long story!). 

H:
What are you excited about?

TM:
When I talk to project teams about how they find and select healthier products for new construction or retrofits, I often hear that they rely on disclosures like Health Product Declarations (HPDs) or Declare labels, or ecolabels such as Greenseal or Cradle to Cradle certifications, or most often they rely on manufacturer claims about the product. 

I’m feeling optimistic that there has been more traction with manufacturers using these great transparency programs. There are a limited number of products on the market today that carry disclosures, and even fewer that have ecolabels. Real estate teams often feel stuck when the product they want to select is not yet disclosed. Also, because a product carries a disclosure or an ecolabel does not mean it is the best choice to avoid hazards for that product category. 

I believe that there is a lot of value in disclosures and product certifications and that they play a critical role in our ecosystem. And, I believe the most powerful way to achieve safer products is to start BEFORE relying on those product disclosure tools. Project teams can take advantage of product type guidance to select products that are typically safer than others – all before ever selecting from an individual manufacturer.

Habitable’s InformedTM product guidance is informed by our 20+ years of building materials research. Guidance for individual product categories are generated by analyzing everything we know about a product category, including the way the products are made, the hazards associated with the product content, and end of life options for different product types. The reason I am so excited about this resource is that it summarizes a LOT of technical information into a simple, easy to use format that can be applied easily to both benchmark current practices and select typically safer products for projects, and even help document the powerful impacts of choosing safer materials on a project. 

H:
What advice do you have for up-and-coming leaders in this space?

TM:
Don’t be afraid to reach out directly to professionals to learn more about their jobs. Ask what experience they are looking for in candidates, what their day to day looks like, and even directly ask about open positions or internship opportunities. Once you are in a role, actively look for opportunities to meet people within and outside of your organization. By expanding your network you learn different perspectives and build your capacity to collaborate on your next project. I can say from experience that you can make an impact from many different vantage points. We need young energetic leaders in NGOs, government, industry, and academia who are passionate about making the world a better place!

Healthy Building Network (HBN) is excited to welcome Monica Nakielski as our new Board Chair!

“I was excited to join an organization having the impact that HBN does. Our influence and impact spans across industries and the globe with the science and resources we create,” Monica said. “I was interested in networking with other leaders in this space while contributing to the conversation and bringing a healthcare perspective to the table.”

A longtime champion of healthy buildings and spaces, Monica is the former Vice President of Sustainability at Advocate Aurora Health. She has over 15 years of experience as a sustainability practitioner and consultant to Fortune 500 organizations, governments, institutions, and nonprofits, with a focus on health care, hospitals, and health systems.

Monica has long had a passion for healthy materials. Traveling to her mother’s home country of Ecuador years ago, she was deeply impacted by the visible effects of industrial processes and pollution. It was clear that in those communities – like many in the US and around the world – it was the already marginalized communities who were bearing the brunt of the impact of our choices. 

Monica first connected with HBN in 2011 at a BizNGO gathering, where she began to learn about the deeper connections between health and the built environment and the way business and product decisions can deeply impact both. She quickly became an advocate for healthier materials and joined the HBN board in 2019.

A commitment to create healthier spaces for patients, staff, and communities has shaped Monica’s career for more than a decade. Before joining Advocate Aurora Health, she served as the head of sustainability at Blue Cross Blue Shield of Massachusetts (BCBSMA), where she and her team worked to influence health insurers to be leaders of environmental sustainability. She also led and managed sustainability at MassGeneralBrigham (formerly Partners HealthCare) across 16 facilities and 18 million square feet.

A Both-And Approach

As a leader in sustainable healthcare, Monica has been a vocal advocate for integrated approaches to creating safer and healthier spaces. She pushes back against the false dichotomy many practitioners feel of having to choose between climate or chemicals – i.e., focusing on energy efficiency or low-carbon choices versus eliminating toxic chemicals from products and the supply chain. She believes that both approaches can and must be aligned and integrated to create truly healthy spaces for all.

One of her proudest successes was impacting the amended fire code while working for a healthcare system in Boston in 2013. She had the opportunity to advocate with the Boston City Council to ensure that the new fire code met both public safety and public health needs. They were successful in removing toxic flame retardants from the requirements, which directly impacted the administrative headquarters they were building at the time. For that project, Monica’s team was successful in ensuring that more than 70% of the materials used in the building interiors avoided the worst  chemicals of concern.

Monica is committed to blazing a trail and bringing others along for the journey. “We are able to drive this cultural shift and change, all the way down to selecting healthier, safer products, while we’re assuring the same, if not better health outcomes,” she said. “It comes down to connecting with our colleagues and educating them – finding the stories and the information that will inspire them to act.”

Monica believes that HBN is well-positioned to lead this work and create a healthier, more just world. “It’s up to us to lead, to share, to continue to collaborate, network, and leverage the science, tools, and resources that HBN publishes.”

A Bright Future for HBN

Monica is incredibly excited for the growth and expansion that HBN is poised to take on in the coming years, and we are fortunate to have her as a leading voice guiding the way.

“What I find most exciting is that these discussions are bubbling up everywhere. With new ESG reporting standards and rules, people are being held accountable. I love the idea of continuing to raise awareness and drive perception, tying it back to the science. For people who have worked in the space of sustainability, we have waited for a really long time for people to connect the dots and to get as excited about this work as we are.”

We are grateful for Monica’s leadership and commitment to helping us achieve our vision that all people and the planet thrive in a world free of toxic chemicals.

“I want to leave the world a better world for my kids, and their kids, and the generations that follow,” she said. “I think we all do.”
