This chapter in ILFI’s book The Regenerative Materials Economy explores the often overlooked life cycle chemical and environmental justice impacts of building materials, focusing on insulation materials like fiberglass and spray polyurethane foam (SPF).
Through a framework rooted in green chemistry and environmental justice principles, authors Rebecca Stamm of HBN and Veena Singla of NRDC analyze manufacturing realities, environmental justice concerns, and environmental health impacts, providing recommendations to improve the industry’s sustainability and reduce the negative effects on marginalized communities.
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.
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.”
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.”
The idea of a “plastic building” might bring to mind Barbie DreamHouses or Lego towers, but probably not the real life spaces we occupy every day. However, plastics have a long history of use in construction and are increasingly being used in a wide variety of building products.
What are plastics?
Plastics are synthetic or semi-synthetic materials typically made from fossil fuels and their byproducts.1 Depending on the plastic’s intended use, they may also be combined with a variety of additives such as stabilizers, fillers, reinforcements, plasticizers, colorants, and processing aids, many of which are toxic chemicals that are linked to chronic disease. They are a material of choice in the built environment, however, they come with a host of deeply rooted problems.
Durable plastics are the new “frontier”
As the energy sector shifts away from fossil fuels, the fossil fuel industry has turned toward plastics as a way of maintaining demand for their products.2 An International Energy Report from 2018 showed that petrochemicals, which are used to make plastics, are slated to become the largest driver of global oil demand in the near future.3 Historically, much of the investment has been in single-use plastics, which are increasingly the focus of bans, restrictions, regulations, and product innovation due to their harmful environmental effects.2 To pick up this anticipated slack, petrochemical, fossil fuel, and plastics industries are now pushing to increase their market growth in more durable goods, like building materials.4 The building and construction industry is already the second largest consumer of plastics after packaging.5
Plastics contribute to climate change
Plastics contribute to greenhouse gas emissions at every stage of their lifecycle. Greenhouse gases are released during fossil fuel extraction, transport, feedstock refining, and plastic manufacture, and carbon is released into the atmosphere through degradation and incineration at plastic products’ end of life.6 A 2019 Center for International Environmental Law report concluded that these lifecycle emissions may make it impossible to keep global warming below 1.5 degrees if growth continues as projected.6 Any comprehensive climate change plan must curb the production of plastics.
Plastic is ubiquitous in buildings
Maybe you know that vinyl flooring is plastic, but did you know that latex paint is mostly plastic? That many insulation products are plastic? How about carpet? Plastic-containing products can be found in almost every part of a building, from the waterproofing on foundations to roofing materials. See below for an infographic showing just some of the plastic materials in an average home. The products included are not exhaustive, but rather a list of example product types from Habitable’s InformedTM product categories where a main component is plastic. There are many more products that are predominantly made of plastic, and even more that contain smaller amounts of plastic additives or plastic binders.
Our plastic buildings are driving the growth in fossil fuels at the same time as we are diligently working to incorporate clean energy solutions and decarbonize these very same places.
Hidden costs of cheap plastic
Plastic products are often favored due to their “low cost.” This low retail cost is achieved by avoiding and externalizing the costs of fossil fuels and industrial pollution – and their related chronic diseases – throughout the plastics supply chain. These externalized costs are real and paid for by the BIPOC and low-income communities across the nation who are disproportionately burdened with toxic pollution flowing from refineries, chemical manufacturing, and plastics plants. It is fair to say that most of the stories about environmental justice that you have heard can be linked to plastics manufacturing.
With the building and construction industries anticipating growth over the next several years,7 commensurate growth is to be expected in their use of plastics. Indeed, market trends and projections show a steady increase in polyvinyl chloride (aka vinyl), polystyrene, polyethylene, polyurethanes, and other plastics used in building materials.8
It is, of course, unrealistic to avoid all plastic in building materials at this time, but there are steps we can take to reduce plastic waste, decrease toxic chemical use, and curb the demand for fossil fuels.
Select Better: Avoid worst-in-class plastics where possible.
Prioritize Transparency: Prefer products that provide transparency
Aim for Circularity: Select products designed for recycling.
With all of these plastic products, our buildings may seem increasingly like Barbie’s DreamHouse and a climate nightmare, but as specifiers, designers, architects, contractors, and owners we can do much to control what products end up in our projects. Starting with the recommendations above, we have the power to influence demand for better and safer materials. In the case of plastics, choosing better materials can lead to less reliance on fossil fuels, fewer greenhouse gas emissions, a decrease in toxic chemical use, and a win for our changing climate.
Simona Fischer, MSR Design
As registered architect, sustainable design professional, and associate with MSR Design, Simona Fischer has spent much of her career thus far developing and testing strategies for integrating sustainable design into the workflow of architectural practice. Her experience includes project management, Living Building Challenge documentation, and firmwide sustainable design implementation.
Simona is a dynamic community of practitioners who help co-create solutions to accelerate the adoption of healthier building materials in affordable housing. She has presented at national conferences, lectures regularly at the University of Minnesota, and currently co-chairs the AIA Minnesota Committee on the Environment (COTE).
Simona was instrumental in the Living Building Challenge Petal Certification of MSR Design’s new downtown Minneapolis headquarters, which achieved the materials, beauty, and equity petals. The project incorporated more than 114 Red List Free materials and achieved a 28 percent reduction of its embodied carbon footprint by using salvaged materials. She also led the development of guidelines around transparency, sustainability, and health for the firm’s materials library, including training materials for staff and external sales reps.
We sat down with Simona to learn why materials have been a focus of her career and to get her perspective on the green building industry today.
What sparked your passion about healthier materials? Was there an “aha” moment or a time that something just clicked?
I was that kid who won a prize for designing the elementary school recycling banner, so I guess I’ve cared about materials for a long time. But my interest in building materials was piqued in architecture school, when we were challenged to create a new ecolabel. Faced with inventing a way to compare one material to another in terms of sustainability, I realized how mind-blowingly complex of a task that was. How do you make the criteria objective? How do you compare products across categories? How do you measure health – is it just by the list of ingredients, or do you include research on health outcomes factoring exposure and risk (and if so, what research even exists)? How do you stack human health and other metrics against each other and choose which factor outweighs the other? How do you account for performance and durability? The questions were endless and led to more questions, which I found complex and intriguing. In other topic areas like water and energy in buildings, the goal seemed straightforward (at least on the surface). Use less energy, and make it cleaner. Use less water, and make it cleaner. But with materials, the number of variables were infinite. We had to think about balancing not just toxicity to people and embodied carbon, but also harvesting of raw materials, ethical manufacturing, and what to do with all that stuff at the end of its useful life.
I ended up writing my MS thesis on methods for assessing sustainability at the level of the manufacturer, as opposed to focusing solely on individual products which change so frequently. I was really just trying to find a system map at a higher level, and make the big, shifting world of materials more manageable in my head. I still use some of what I learned during that project as indicators of whether a building product manufacturer is serious about human health and sustainability, or just greenwashing. But sometimes they are greenwashing because they don’t know any better, and they are on their way to improving. So you can’t just write off smaller companies who don’t yet have all the documentation. It’s a learning process for them as well.
At MSR Design, the conversation about healthy materials had already started when I joined to work on The Rose, a Living Building-inspired affordable housing development in Minneapolis. My colleagues Rhys MacPherson, Paul Mellblom, and Rachelle Schoessler-Lynn were leading the conversation about why we should, and how we could, avoid vinyl and other chemicals on The Rose and on other projects across the firm. Over the next couple years we held a number of all-staff discussions and training sessions on healthy materials. Many staff members, from seasoned designers to interns, became interested in the question of how we could do better while still delivering a beautiful aesthetic and the best functionality for our clients. By the time we were ready to start designing our new studio, healthy materials as a concept had had enough time to become embedded in the culture
Tell us about your project to build the new MSR studio. Why was it important to prioritize healthy materials for this project? What went into your process?
When we knew we were moving, we held an all-staff discussion to debate frameworks for certification. We considered LEED, WELL, Fitwell, and Living Building Challenge Petal Certification. In the end, LBC won, because the Materials Petal was so ambitious, prioritizing not only human health through the use of Red List Free products, but also environmental health and other butterfly-effect impacts of resource harvesting and global warming potential and waste. At the same time, the LBC path included an emphasis on equity, as well as using the project as a tool to educate and inspire others. We found the holistic approach inspiring, and appreciated the challenge (most days).
It was important to prioritize healthy materials because we knew our staff cared about living out our values around healthy indoor environments. I think the team will agree that meeting the Red List requirement was difficult. It took time to develop a workflow for gathering the documentation. But it also gave us the opportunity to rethink the way we approach materials from the start of projects. Instead of trying to weed out all the “bad” chemistry, we found it was actually easier to start from scratch and build up a list of materials we knew were likely to comply with the requirement. It ended up being simpler, mostly natural materials, which we used as the palette for our space.
How do you consider low embodied carbon versus health in product selection?
Non-toxic materials and low embodied carbon are two lenses on a singular problem, which is planetary health. Human health is a subcategory of planetary health, since we’re part of the planet and made of its stuff. When indoor and outdoor environments, and plant and animal and human bodies, are polluted by toxic substances, both from human-made toxins and an overabundance of greenhouse gasses, the global ecosystem suffers and humans suffer within it. We are nature. What’s interesting is, younger, upcoming professionals and design students seem to understand this intuitively. They don’t even need to be told that human and global environmental health go hand in hand. So I think as an industry, we just need to accept the interplay of embodied carbon and human health as a foregone conclusion and get straight to the nitty-gritty of what materials we use and how those materials are grown, produced, manufactured and delivered.
That said, we also need to get serious about the data used to back up carbon and health claims. We need transparent, standardized reporting from manufacturers, including making sure the scope of every life cycle assessment (LCA) takes all the impact categories of the AIA Materials Pledge into account. I think petroleum-based building materials are going to be a battleground for a while to come. The low purchase price and saturation in the market make plastics seem like an easy choice for all kinds of different finishes and performance layers in buildings. It is possible to make them somewhat healthier for end-users by being careful to avoid certain additives. But that leaves a massive loophole; the impacts of production and waste on planetary health. I think there’s an opportunity for data to drive a new understanding here. If we can start seeing standardized collection and data crunching of environmental product declaration (EPD) data from different product sectors, we might be able to correlate carbon from building products more directly to regional health impacts of the production of those chemistries. This would help close loopholes that allow the incredible health impact of high global warming potential (GWP) emissions to stay hidden in the shadows
How have you used your knowledge to help move your clients toward healthier materials? What has been most successful?
I think some of my most successful work has been in addressing priorities and processes in our workflow. I can’t count the number of times I’ve heard people say they just wish there was a single, simple database of all the great products. There are ever-improving databases out there, but people always want something else that is missing, so the problem hasn’t been solved. I think the missing piece is a deeper understanding of the principles of product categories, such as knowing what different types–not brands, but general types–of insulation or countertop materials are made of, and where they come from. This level of knowledge, over time, becomes a kind of intuition one uses to filter the world of products even as new things constantly appear in your inbox or your lunch and learns. When you understand the principles, and don’t just rely on a database to provide a solution, it also gets easier to speak knowledgeably and make solid recommendations to clients.
On project work, I have the best luck when I’m upfront about why we need to consider material health alongside cost. You have to tailor your message to the audience, for example, some clients are most receptive to the idea of improving their impact on the world, whereas for others, the message that hits home is one of directly affecting their health or the health of people they care about
How has Habitable’s InformedTM building product research been helpful or influential?
I love InformedTMand recommend it to designers all the time, and clients too. The information is organized in terms of product categories as opposed to brand names or labels, so it aligns with the level of learning that I think is most beneficial to becoming smarter in practice. We used the sample specs to rewrite our paint specifications in 2021. We’ve also heard great lectures from Habitable research team members over the years that have left an impact on our staff.
What advice do you have for other AEC leaders? Are there processes or approaches you would recommend? Where would you recommend a newcomer to healthier materials start?
For designers, I recommend signing the AIA Materials Pledge and studying the categories. The Pledge is a great framework – if you address each of the Pledge categories in some way, you know you’re hitting the right bases. If you can, allot some time to staff education and discussion. I recommend the Living Building Challenge Materials Petal as a particularly inspiring framework for education and good discussion, because it is based on absolute goals, instead of relative improvement. The COTE Super Spreadsheet (downloadable on the AIA website) is a good starting point for addressing materials issues in an applied manner on projects.
At MSR Design, our internal education efforts led to the development of our Material Library Entry Criteria. If others want to design similar criteria for their libraries, they are welcome to copy ours outright or modify as needed: www.msrdesign.com/generative-impacts.
The more we as designers align in our message to manufacturers about health and carbon, the easier it becomes for them to stay in business while giving us what we want
What are you most excited about right now?
I’m excited about natural and biobased materials. On the high-tech side, there is so much opportunity for new materials to be developed, especially bio-based polymers. On the other hand, there is a new straw bale project that is being built in Minneapolis. It’s low tech in comparison to the latest research in biomaterials, and yet it combines healthy, natural materials seamlessly with low carbon construction. The team is using Passive House building science principles to build a durable system, which they will test with sensors in the walls over the next few years. I really resonate with the idea that we can build a sustainable future with natural materials in both high- and low-tech ways
What do you want other people to know?
We, as an industry, are practicing architecture and construction in an era where buildings are made of hybrid material systems so complex, we hardly know what’s in them or why they work. I think we architects can perhaps find evidence of the Vitruvian virtues of utilitas (utility) and venustas (beauty) in the work we produce, but somewhere as a profession, I think we have let go of the firmitas (stability). Not in the sense of solid structure, but in the sense of owning materiality and material knowledge as a critical aspect of an architect’s role. We have become accustomed to accepting a level of vagueness about assemblies and their tons of little components, and leaving the details to the product manufacturer. I think understanding materials deeply is about reclaiming this knowledge, and a piece of architecture we have lost

PFAS are used in paints, food packaging and even cosmetics. We know they are in our water, air, soil and bodies – but less about how they will affect us.
Health Care Without Harm Europe advocates for the complete elimination of PVC due to its environmental impact, urging policymakers to develop a strategy for its phase-out in Europe.
Healthy Building Network (HBN) and 100+ organizations stand united behind the new Louisville Charter for Safer Chemicals, a roadmap for transforming the chemical industry to one that is no longer a source of greenhouse gas emissions and significant human and environmental health harms.
The goal of the updated charter is to protect human health and the environment and achieve environmental justice for all who experience disproportionate impacts from cumulative chemical sources, including people of color, low-income people, Tribes and Native/Indigenous communities, women, children, and farmworkers.
The original Charter was created in 2004; at that time, HBN joined a broad coalition of grassroots, labor, health, and environmental justice groups in an extensive process initiated by community organizations in Louisville, KY. Louisville’s “Rubbertown” area hosted 11 industrial facilities that released millions of pounds of toxic air emissions every year. The Charter was named in honor of this city and all of the communities across the nation exposed to toxic chemical contamination—starting with the people who are harmed first and worst. We participated in the 2021 update process, supporting the efforts of the most heavily impacted communities to more explicitly address the chemical industry’s massive contribution to the climate crisis, and the need to advance environmental justice in communities who are disproportionately impacted.
The Louisville Charter is a unifying guide for everyone working to ensure that toxic chemicals are no longer a source of harm, from local and national policy-makers and labor organizers, to health care workers and concerned community members, to committed leaders in the building industry. It is meant to be versatile and used in a wide variety of contexts for one overarching purpose: to overhaul chemical policies in favor of safety, health, equity, and justice, and avoid false solutions that simply shift harms to other people and places.
HBN is proud to be a signatory of the Charter and join this diverse and intersectional community of partners demanding urgent action to protect, strengthen, and restore our most vulnerable communities.

If you’re reading this article, you’ve probably begun your journey in understanding the impacts that building materials can have on human health and the environment. But it can feel daunting to know where to start applying this knowledge to your work. You may feel like you don’t have the time or budget to select materials that are free of hazardous chemicals.
Fortunately, there are some relatively simple, low- or no-cost ways to start incorporating healthier materials into your projects right away. By focusing on a few high-impact product categories with readily available healthier products, you can begin the process of preferring and specifying healthier materials without making significant changes to your bottom line.
Assuming that healthier materials always cost more is a common misconception that often stops healthier material initiatives from even being discussed. Here are a few things you can do to start your journey without impacting your budget.
Paints
Paint is one of the easiest categories to start with, as healthier alternatives are readily available with no cost premium. Most paints today have Low or Zero VOC content and emissions and that are free of the endocrine-disrupting chemical APEs (Alkylphenol Ethoxylates), which are also toxic to fish and other aquatic organisms. “Endocrine disrupting” is a fancy way of saying they mimic hormones and send false signals, which cause problems in humans, and are especially problematic to children whose internal systems are nascent and developing.
Carpets
Avoid the use of carpets with stain repellents or stain treatments. PFAS is the chemical name often cited as a worst-in-class stain and water repellent chemical, and in performance testing, it often falls short of the job it is purported to do and instead, it rubs off and enters our bodies.
Insulation
Whenever possible, avoid the use of spray foam insulation, which is reacted onsite and can expose installers and building occupants to hazardous ingredients that can cause asthma. Prefer fiberglass, formaldehyde-free mineral wood, or cellulose insulation.
Use our InformedTM product guidance to quickly and easily find healthier products.
Antimicrobials
Avoid building products marketed as “antimicrobial” or “containing antibacterials” or similar claims. Some products on the market today include antimicrobials that are added for the purpose of making marketing claims around a product’s potential health benefits. However, there is no evidence that these added chemicals improve human health, and ironically, they can cause harm.
When looking at costs, there are a few strategies you can engage to tip the scales in your favor.
Start early in the design process
Consider the use of safer materials early in the design. Late design changes can increase the cost of your project and impose technical constraints that limit opportunities for incorporating certain types of materials. If cost remains a barrier, make sure to include safer materials as an alternate option in your specifications in case that funds become available later in the project.
Leverage purchasing power
By simplifying your material pallet and buying in volume, you may be able to secure better pricing for a healthier product across your organization’s entire portfolio. You can also leverage collective purchasing power by working together with other organizations via affordable housing collectives and associations like the Housing Partnership Network (HPN).
Save by cutting waste
Revisit your design process and emphasize waste minimization. For example, design a floor plan that minimizes cut off waste of your chosen flooring material. The savings you generate can be allocated to the purchasing of healthier materials.
With all this said, the reality is that sometimes safer materials do have a higher upfront cost. However, we hope this article has demonstrated that it’s possible to start prioritizing healthier materials no matter your budget or project size! Together we can all take steps toward a day where all people and the planet thrive in an environment free of hazardous chemicals.
