Cracking the (Building) Code on Flame Retardants

Melissa Coffin | September 18, 2014 | Materials

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...

Melissa Coffin | August 05, 2014 | Materials

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.

One Tiny Problem with Mortar & Grout: Nanosilver

Melissa Coffin | May 19, 2014 | Materials

When we opened a Pharos product category for Ceramic Tiles last month, the mortars and grouts required to install them were a bit of an afterthought: essentially cement, we assumed, adding these products to Pharos would be a snap.  As it happens, we were wrong on both counts.  Far from just cement, there is a wide range of chemistries u...

Hungry Building Products?

Melissa Coffin | October 25, 2013 | Materials

A few months back we took a look  at so-called “self-cleaning” products: products that manufacturers promise will deliver air-purifying capabilities in addition to their primary function in construction.  We initially focused on products using the photocatalysis of titanium dioxide to convert nitrogen oxide air pollutants in...

Melissa Coffin | July 23, 2013 | Materials

Can building products make the environment cleaner and healthier? Has the first generation of "pollution-eating," "regenerative" materials arrived? A growing number of products are claiming to remove everything from VOCs from interior environments to auto-exhaust on highways. The apparent wizardry behind some of these product...

Self-Cleaning or Greenwashing? New Product Claims Raise Questions

Melissa Coffin | July 22, 2013 | Materials

Over the course of our work with manufacturers, the Pharos team often learns of creative and innovative new building products.   The latest: products that, in addition to performing their standard function in buildings, also claim the ability to actively improve the air quality where they are used and installed.  Do these products...

Reintroducing Pharos Team Notes

Melissa Coffin | July 09, 2013 | Optimizing Recycling

The Pharos team is often on the receiving end of phone calls or emails from our users who have questions about our building product evaluations – the meaning of a flag or hazard association, or why we’ve listed a product with a particular level of completion or participation.

While we’re always happy to talk about our approach...

From Compost to Composites: Innovating with Cow Pies

Melissa Coffin | July 27, 2011 | Materials

Earlier this month I was introduced to a new product for Pharos, a line of wall boards and panels made from a blend of cellulose sources -- recycled cardboard, old newsprint, and something near and dear to my Vermont heart: bovine processed fibers.  Yes, BPFs as they're known, are the fibers left over from the anaerobic digestion tanks use...
