Grayworks is a modular, plug-and-play commercial graywater treatment system that simplifies installation and maintenance.
When we turn on a faucet in the U.S., it’s easy to think that the clean water that comes pouring out is a limitless resource. But fresh water is a precious commodity and it takes a lot of energy and resources to filter, sanitize, pump, and transport potable water into our buildings, and then out again as wastewater.
We can reduce our... Read more

Focused solely on net-zero-energy performance, the new certification aims to distinguish projects that verify outcomes with actual data.
As more projects started claiming “net-zero-energy design” without having actual performance data to back them up, a certification and a certifying agency became needed. International Living Future Institute (ILFI) and New Buildings Institute (NBI) have now teamed up to fill this gap and accelerate the net-zero-energy trend.
Earlier in... Read more

The challenge might seem greater, but focusing on schools is crucial as climate change advocacy moves to local leadership.
On the same day that our editorial team finalized this month’s feature article on net-zero-energy schools, President Trump withdrew the United States from the Paris Climate Accord.
As I re-read the article, my own words seemed tone-deaf in the context of this new reality. The past few years had given me optimism that green building was... Read more

Schools are leading the way in net-zero energy, but some designers question whether these goals create the best learning environments.
In Portland, Maine, the chair of a building committee dreamed of a schoolhouse that could offset the transportation energy required for students to commute to class.
In Arlington, Virginia, a school architect argued he could reduce energy costs without increasing his budget.
In Cambridge, Massachusetts, the school district,... Read more

Proponents of the circular economy point to PaaS as one of the strongest tools we have to take control of our energy and material waste.
What if instead of buying a light bulb you paid a company to provide you with light? That’s the idea behind product as a service (PaaS)—a business model that could extend to any type of building product and seeks to bring about a circular economy.
This is how it works. An owner specifies the desired performance level for a certain... Read more

Nedlaw Living Wall Biofilters do more than most green walls to remove VOCs, but it’s unclear that they provide a true fresh air supply.
Living walls, or green walls, can provide a powerful connection with nature in otherwise sterile urban interiors. But plants used as interior decorations have been consistently overhyped as tools for everything from cleaning indoor air to increasing productivity (see Bringing Nature Indoors: The Myths and Realities of Plants in Buildings)....

Thermafiber and Roxul have introduced the first formaldehyde-free mineral wool batt insulations, following the example set by the fiberglass insulation industry.
BuildingGreen has been asking for formaldehyde-free mineral wool insulation for years (see The Search for Better Insulation). In 1996, fiberglass batt manufacturers began replacing formaldehyde—a carcinogen and respiratory irritant (see our primer on formaldehyde)—with acrylic resins. In 2008, formaldehyde-free biobased resins arrived. And... Read more
