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!

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.”

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

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.

“Cuando llegué aquí, mi apartamento estaba a punto de desmoronarse. Tuvimos muchos problemas; las alfombras eran increíblemente viejas y encender el aire acondicionado era como tener un helicóptero dentro de la casa”. Estas son las palabras de Vanessa del Campo.

Vanessa nació y creció en México, y como muchas otras personas, se mudó a los Estados Unidos en busca de mejores condiciones de vida. Ahora vive en Minnesota y alquila un apartamento en un edificio multifamiliar ubicado en una de las áreas designadas por la Agencia de Control de Contaminación de Minnesota (MPCA) como de interés de Justicia Ambiental. Su experiencia como inquilina está marcada con historias de desalojos injustos, preocupaciones de salud, y batallas constantes con propietarios que negaron su derecho a incluso las condiciones más básicas de vida.

Afortunadamente para Vanessa y otros vecinos en su edificio, ella recibió el apoyo de Inquilinos Unidos por Justicia (IX), una organización comunitaria que les ayudó a organizarse y movilizarse para recuperar los servicios que desesperadamente necesitaban para mantener su salud y bienestar. Lo que comenzó como un esfuerzo organizado para solicitar nuevas ventanas para un pequeño número de apartamentos, se convirtió en una larga pero exitosa tarea para comprar el destartalado complejo de apartamentos y asegurar un préstamo para renovar todas sus unidades.

“Pasamos por muchos litigios con el propietario porque no estaba haciendo las reparaciones que necesitábamos y no quería vendernos los edificios. El año pasado, cuando llegó la pandemia, finalmente obtuvimos la oportunidad de comprar el edificio. Fue un momento feliz y difícil porque estábamos aterrorizados de enfermarnos [con el virus], pero logramos organizarnos y apoyarnos unos a otros. Hoy estamos trabajando con una nueva empresa de administración de propiedades y el banco para instalar alfombras, pisos, techos, ventanas, hornos, refrigeradores y baños nuevos. Estamos haciendo una profunda renovación para llevar todos los apartamentos a un estado que es mucho, mucho mejor que el que teníamos”.

Es fácil dejarse llevar por la emoción de Vanessa mientras habla de esta nueva oportunidad. Ella mencionó que su bebé tuvo dificultades para aprender a gatear porque era demasiado peligroso colocarle en el suelo debido a las ratas y cucarachas que a menudo rondaban la casa. Al mismo tiempo, también es fácil olvidar que además de ser madre y tener un trabajo exigente, ahora tiene que cumplir el rol de copropietaria de un edificio como miembro principal de un recién formado colectivo de residentes (Un Cielo Sin Límites).

Con tanto trabajo invertido en la compra y renovación del complejo de apartamentos, los residentes tuvieron poco tiempo para pensar en la seguridad química de los materiales de construcción que fueron utilizados en sus apartamentos. Ahí es donde entra Healthy Building Network (HBN, o, La Red de Edificios Saludables). A principios de este año, MPCA otorgó a IX y HBN una subvención para reducir la exposición a sustancias químicas tóxicas entre los niños, las personas embarazadas, los empleados y las comunidades que se ven afectadas de manera desproporcionada por sustancias químicas nocivas utilizadas en productos comunes.

Un ejemplo de sustancias químicas tóxicas en los hogares son los ftalatos u ortoftalatos, que son sustancias químicas utilizadas para ayudar a dar flexibilizar a los plásticos. Estas sustancias también pueden afectar el desarrollo adecuado de los niños. Estos productos químicos están prohibidos en los juguetes de los niños en los EE. UU. El Departamento de Salud de Minnesota, en asociación con MPCA, nombró a los ftalatos como “productos químicos prioritarios” como parte de la Ley de Niños Libres de Tóxicos de 2017. Si bien muchos fabricantes han eliminado los plastificantes de ftalato, estos químicos están presentes en los pisos de vinilo existentes, especialmente los instalados antes de 2016. Esto se traduce en docenas de libras de estos químicos peligrosos en el piso de una sola unidad de apartamento. A medida que estos productos químicos se liberan de los productos, se depositan en el polvo que los residentes pueden inhalar o ingerir, afectando especialmente a los niños pequeños que gatean por el suelo y a menudo se llevan las manos a la boca.

“Honestamente, nunca nos detuvimos a pensar en lo dañino que podrían ser los materiales [de construcción]”. Dijo Vanessa. “Fue lamentable ver cómo vivíamos. Entendemos que los materiales que se utilizan en nuestros edificios hoy en día pueden no ser los más saludables. Hoy nos damos cuenta de que es importante pensar en cómo queremos vivir en nuestros hogares, imaginar la calidad de vida que queremos en nuestros edificios, en nuestra comunidad”.

Durante el próximo año, HBN trabajará con IX y el colectivo de residentes para evaluar los materiales utilizados en su proceso de renovación y brindar recomendaciones para mejorar la selección de materiales. También desarrollaremos recursos para ayudar a los residentes a entender cómo el entorno circundante influye en su salud. Para extender el impacto de este trabajo, crearemos y compartiremos un conjunto de mejores prácticas para que los administradores de propiedades y las organizaciones de inquilinos puedan abogar por utilizar materiales más saludables en las comunidades en las que viven y en las propiedades que administran.

“Nuestra colaboración con HBN es oportuna. Al trabajar junto con los administradores de propiedades, podemos aumentar su conciencia sobre cómo su trabajo impacta nuestra salud y ayudar a cambiar la forma en que seleccionan los materiales”, dijo Vanessa.

En Healthy Building Network, estamos agradecidos por la oportunidad de trabajar con IX y líderes locales como Vanessa a través de la subvención otorgada por MPCA que hace posible esta colaboración. Hacemos un llamado a las agencias públicas, fundaciones e inversionistas privados para que financien iniciativas que busquen desmantelar las inequidades en salud a través de inversión en las comunidades impactadas de manera desproporcionada por la injusticia ambiental, especialmente relacionada con la exposición a sustancias químicas tóxicas. Esperamos pronto poder compartir con ustedes las lecciones, historias y recursos que surgen de esta colaboración.
