Healthy Building Network (HBN) is proud to introduce HomeFree, a national initiative supporting affordable housing leaders who are improving human health by using less toxic building materials.

Though all people are impacted, low-wealth communities are disproportionately exposed to chemicals hazards on the job, in their neighborhoods, and within the home. We spend up to 90 percent of our time indoors. Today's buildings can contain many different chemicals of concern. From lead poisoning to asthma, our building materials can impact our health as much as the food we eat, the water we drink or the air we breathe.

There has been a growing effort to create programs that mitigate health disparities. Yet, there is a significant and critical health component still being over-looked – chemical toxics in the built environment. Working together, it is possible to make informed choices about affordable, healthier materials, as part of a complimentary and holistic health approach, minimizing the health gap of low-wealth communities.


Most people think that chemicals used in building products are strictly regulated or tested for human health impacts, but that is not the case. In fact, it is difficult to get clear and reliable information about product ingredients. Even manufacturers are often uninformed about the chemicals in their products, and many chemical companies refuse to disclose the details. Often healthier options come at a price premium or performance deficiency.

However, it is also true that there are available healthier and affordable product options with equal or superior performance. Today is a time of extraordinary innovation in the building products industry. A new transparency movement led by our partner, Health Product Declaration Collaborative, is making information about building products more accessible. A growing array of assessment tools, such as HBN’s Pharos Project, is making it easier to assess and compare health hazards in building products. Another partner, Green Science Policy Institute, is focused on reducing harm to communities from classes of chemicals of concern, starting with flame retardants in furniture and building insulation. Manufacturers are listening, innovating, and optimizing their building products at an unprecedented rate. Across the country, there are recent examples of affordable housing providers who have successfully identified and installed superior materials. HomeFree will share that data and help affordable housing providers keep pace with these changes, make informed decisions and engage with manufacturers to make high performing, healthier products available at price points that work for our industry.


Our work brings together the passion, commitment and expertise of two dynamic communities. It is based on the premise that our affordable housing community partners possess critical skills and experience, and knowledge of regionally specific solutions. Our environmental health partners will help us connect the dots between the toxics in our built environment and human health implications – like asthma, developmental delays, cancer, and more. We will learn from each other and co-create actionable strategies for healthier buildings. Our open-source data and best practices through HBN’s HomeFree web platform are accessible to anyone and everyone.

HomeFree will harness the affordable housing sector’s collective wisdom, influence, and buying power to support group purchasing initiatives that will create incentives for manufacturers to provide superior products.

Communities of Practice
United States


HBN is launching HomeFree with six communities of practice. Each will have a demonstration project to test and model best practices, and identify superior products. HBN staff will provide support to each project team. Local advisors will engage and shape the HomeFree approach, and share knowledge with an involved regional cohort. Regional activities and outcomes will advance national change. We will work together to influence and shift the responsibility of transparency and health disclosure onto the chemical industry and product manufacturers.

We will first begin by targeting commonly used products in the dwelling unit since that is where people spend the most time. It will include product categories such as flooring, drywall, paint, countertops, cabinetry, doors, etc. This focused approach will allow us to rapidly scale.

Using a new scientific methodology created by HBN called the Avoided Hazards Index, we will compare chemicals and related health hazards in building products, and show the impact of informed choices.

This example shows that selecting healthier flooring will eliminate roughly 351 pounds of toxic chemicals in a single two-bedroom apartment. That means, in a 90-unit apartment building, over 11 tons of hazardous chemicals will have been avoided – one product, one building!! Imagine the magnitude of impact when numerous buildings make one change, or envision the scaled benefits of multiple product swaps.
