Back in 2013, when LEED version 4 was just emerging, the push for information transparency in building materials got a boost when a host of major architecture firms put a stake in the ground. HKS and then SmithGroupJJR led the way, with public letters requesting that manufacturers provide details about the contents of their products using an... Read more

Editor’s note: PET Resilient was never fully rolled out to market, and the company’s explanations about why have been vague. However, Shaw has now introduced a polyolefin-based LVT replacement it claims is comparable in price to domestically sourced LVT.

If you want to avoid vinyl, there are plenty of resilient flooring options... Read more

The goals of sustainable design and construction have evolved to include an increasing focus on the embodied impacts of buildings in addition to the operational impacts. And although strategies that can achieve these goals have emerged—like net-zero design, onsite renewables, material reuse, and whole-building life-cycle analysis—many can... Read more

Do good intentions actually result in lower energy and water use? The answer is decidedly yes in federal buildings, according to a new report from the U.S. General Services Administration (GSA).

The study compared 100 buildings that meet the Guiding Principles for Sustainable Federal Buildings with 100 “legacy stock” buildings. The... Read more

Project teams looking for tools to help them design high-performance buildings in the U.S. will soon have another option: the BREEAM New Construction standard. 

You may have heard of it. BREEAM (Building Research Establishment Environmental Assessment Method) has been used in countries around the world since 1990. The program has... Read more

A particularly well thought-out and thorough question from reader Aaron Birkland on the pH of phenolic foam and its possible corrosive nature prompted me to follow up my original blog post on Kingspan’s Kooltherm rigid insulation. Aaron has two main questions:

I was at my brother’s house in Lee, New Hampshire, recently and looked up to see that his photovoltaic (PV) panels looked a bit dull (see Image #2 in the slideshow). His PV array is easy to get to—the long north slope of his roof has a walkable 5:12 pitch—so we went up and took a closer look.

It turns out that the PV industry... Read more

Curious about the toxic substances in building products? See a chemical on a Health Product Declaration that you’d like to know more about? You might want to check out the Chemical Hazard Data Commons, a free online resource from the Healthy Building Network (HBN). HBN is a nonprofit focused on reducing the use of toxic chemicals in building... Read more

Buildings contribute to social sustainability by providing environments that support communities in meeting their social needs. It’s generally easy to understand how the design, construction, and operation of buildings affect the environment. A building’s energy use or carbon cost, for example, are objective and quantifiable. But the building’s... Read more

What do we mean when we say sustainable lighting? In this 17-page PDF report, we take a closer look at lighting as an essential element in quality environments that support health and wellness while reducing energy use.

The functionality of a building is largely dependent on the quality of its lighting, which is often treated as a... Read more

The functionality of a building is largely dependent on the quality of its lighting. In order to safely and comfortably perform their tasks, occupants need lighting that provides adequate visibility without causing discomfort or distraction.

But a focus on quality is also the key to achieving sustainable lighting.

As Nancy... Read more

The most energy-efficient LED light is cold, blue, and focused directionally on a small area; it is some of the worst light quality imaginable. Yet in the early years of LEDs, energy efficiency, or efficacy (measured in lumens produced per watt consumed, lpw), was the prime metric for judging LED performance. The industry suffered through a... Read more

Building energy modeling has become more common over the last decade or so, and it’s a standard practice for projects pursuing LEED certification. But there’s a problem: the later the team waits to start modeling the building, the more potential energy-saving opportunities have been missed along the way.

“Often building energy modeling... Read more

If you haven’t used the WELL Building Standard because it seemed too difficult or too expensive, it might be time to give this relatively new rating system another look. And if you were just getting used to the requirements of WELL, hold on to your hat: the newly introduced version 2 is a major overhaul.

Released in May of 2018, WELL v2... Read more

Just after midnight, the skies opened.

Hour after hour, for three hours, a relentless deluge hammered Houston’s Texas Medical Center (TMC), causing nearly $2 billion in damage. Hundreds of patients had to be evacuated.

No, we’re not talking about Hurricane Harvey.

It was nearly 16 years earlier, in June 2001, when... Read more

Imagine going to a gym where you not only burn calories but also generate power—just by working out. That’s the case at Sacramento Eco Fitness, in Sacramento, California, where cycling classes generate electricity that helps power the building.

The fitness center has installed Eco-Powr stationary bikes manufactured by SportsArt, which... Read more

The Powerhouse Drøbak Montessori secondary school in Norway, equipped with solar panels and a ground source heat pump, will produce more energy over its lifetime (close to 30,500 kWh a year) than the total amount of energy that will ultimately be used for its construction, operation, and demolition.

The school, which serves 60 students... Read more

Alphonse Ponson was only 11 years old when Hurricane Katrina darkened the skies and lashed Tremé, his New Orleans neighborhood. At the time, he lived with his mother in the Lafitte public housing project—896 units in three-story brown brick buildings.

Ponson watched from the family’s second floor window as the muddy stormwaters filled... Read more

Dow Styrofoam, Owens Corning Foamular, and Kingspan GreenGuard insulations no longer contain the flame retardant HBCD (hexabromocyclododecane)—a persistent, bioaccumulative toxic chemical (PBT). With these changes, HBCD is no longer being used in either extruded (XPS) or expanded (EPS) polystyrene insulation.

HBCD was the primary flame... Read more
