Combining the Powers of Pharos and Data Commons


HBN is excited to announce that we’re combining Pharos and the Data Commons. On September 6, 2019 we’ll add new functionality and an improved interface in one easy to access platform. The new Pharos will provide open access to a wealth of information to support chemical hazard assessment, alternatives assessment, and informed substitutions. This includes data for over 140,000 chemicals, covering hazard, function, use, and exposure, as well as a forum for discussing critical hazard assessment issues. It will also contain common content and associated hazards for many types of building products, through Common Product profiles.

Two New Account Options

  1. The Basic account provides free access to most of the functionality currently available in the Data Commons, including chemical hazard data.
  2. The Professional subscription allows users to compare larger groups of chemicals, download data on individual chemicals, hazard lists, and compound groups, access additional research on building products, and view a chemical’s Cradle to Cradle Certified™ List Hazards.

Additional details for each account option will be available closer to the release date.

Your current Pharos subscription will continue as a Professional subscription. We are planning a three month transition during which you will have access to both the current Pharos and new Pharos. After that time (estimated early December) the current version of Pharos will no longer be available.

In the 10 years since Pharos first launched, our campaign for transparency in the building product market has inspired a number of other libraries and resources for finding healthy materials and building product contents. In the past few years, we shifted our research focus away from brand-specific products, toward broader guidance in product categories in the form of Common Products, transformation targets, and research reports. With the incorporation of Data Commons into Pharos, we will sunset the Building Product Library as it is today, and better integrate these new research-based resources across the Pharos site in searches and chemical profiles.

If you are still interested in specific product content information, we recommend consulting the HPD Repository, a project of our partner Health Product Declaration Collaborative. Cofounded by HBN, it will continue to use Pharos as the foundation of its chemical hazard reporting.

Finally, if your subscription runs out and you choose not to renew it, your account will switch to a Basic account.

We will provide a tour to help orient you in the new system, and a webinar in late September to demonstrate all the features and answer questions. In the meantime, please contact Michel Dedeo, Manager of Chemical Data Systems at mdedeo@healthybuilding.net with any questions or concerns. We look forward to sharing this with you!
