The Signal: News and Notes from the Pharos Team

HBN, Cradle-to-Cradle Product Innovation Institute, GreenScreen/Clean Production Action and the Health Product Declaration Collaborative (HPDC) announced a new Application Programming Interface (API) at a press conference during the Materials & Human Health Summit at Greenbuild 2014. The API will allow systems like HBN’s Pharos Project and Google’s Healthy Materials Tool to draw manufacturer-provided building product data directly from the HPDC’s Health Product Declaration Builder.    

Earlier this year, the organizations formed a Harmonization Taskforce Group (HTG) to streamline the inventorying of ingredients, screening of chemicals, and hazard assessment. The US Green Building Council and the Google Foundation are funding this collaborative work. The API is the first deliverable pursuant to this funding.

The API will increase uniformity of data shared by manufacturers and greatly simplify distribution of it to a wide...

The 2014 Greenbuild conference and exhibition is happening at the mouth of what has long been described as America’s Cancer Corridor.  Petrochemical plants line the Mississippi River between New Orleans, host to this year’s Greenbuild, and Baton Rouge, the state capital.    Here, multinational corporations have produced a huge share of this country’s carcinogens, like vinyl chloride monomer, the essential feedstock for polyvinyl chloride (PVC) plastic products; and some phthalates, which makes PVC flexible. The industry’s impacts here spawned the environmental justice movement in the late 1980s.

These days, this serpentine industrial stretch could just as well be branded the Asthma Corridor, given the region’s growing production of essential feedstocks for polyurethane systems.  These systems are increasingly popular in building applications, including adhesives, insulation (spray polyurethane foam, known as SPF)...

Recycling is a deeply embedded principle of green building.  From the beginning of LEED®, recycling has stood by itself as an important attribute of material and waste management credits. These credits, in turn, fueled a huge increase in recycled content in many building materials, from wallboard to concrete to carpet to construction fill.

The status quo is about to change.  The green building...

Halogenated flame retardants (HFRs) used in building materials and their breakdown products can be persistent, bioaccumulative, and toxic.  As such, they appear on restriction lists used by many in the green building community, including the Living Building Challenge Red List and the Perkins+Will Precautionary List.   Beyond their environmental or health characteristics, discussion is growing about whether HFRs, or any flame retardant additive, even provide any benefit in a fire in the first place. [1, 2, 3]

While the debate boils over, many US building codes require high resistance to flame even for materials like insulation that are behind thermal barriers and that will have little or no exposure to a fire.  This requires foam...

Building on our review of ceramic and porcelain tiles earlier this year, the Pharos team has added a Sanitary Ware category to our building product library.   Flushometers, toilets, tanks, and toilet seats now appear in Pharos.

This was an interesting experience for us – trying to decipher the material composition of a class of products described only very generally: “vitreous china”, “stain resistant glaze”, or “plastic”.  It seems that ingredient disclosure isn’t a conversation that’s been happening in this sector.  While some products may contain a small amount of recycled content, the primary environmental concern in the industry has been, appropriately so, on water conservation.

Our review of these products uncovered some materials of concern.

First: antimicrobials.  As might be expected in a product category where cleanliness is prized, toilets and toilet seats...
