SolarEdge’s photovoltaic inverter and electric vehicle charging station reduces the number of mechanical systems and simplifies installation.

October 8, 2018

Charging your electric vehicle (EV) at home using renewable energy is the future of transportation. But getting that power to the car typically requires two systems: an inverter and a charger. Photovoltaic (PV) panels use inverters to convert direct current (DC) to alternating current (AC), and a charger typically supplies energy pulled from... Read more

Health advocates worry that new review methods at EPA could cripple the updated Toxic Substances Control Act.

October 8, 2018

It wasn’t perfect, but it was promising. The Toxic Substances Control Act (TSCA), as amended in 2016, was designed to give the U.S. Environmental Protection Agency (EPA) new powers and obligations to study and regulate industrial chemicals.

But if current EPA actions are any guide, the limitations and outright bans that environmental... Read more

A new partnership between the International Living Future Institute and Toxnot will help manufacturers provide better-quality health information.

October 8, 2018

The International Living Future Institute’s (ILFI) Declare label is supposed to be an easy-to-read “nutrition” label for products, showing the product’s ingredients and whether or not it contains any of ILFI’s banned Red List chemicals. This simple document belies the underlying complexity required for manufacturers to track chemicals used to... Read more

Getting stronger sustainability language into the code wasn’t easy, but only because AIA takes these things seriously.

September 24, 2018

David Pill, AIA, had an inspiration as we were planning the third annual AIA New England Committee on the Environment (COTE) Summit, which took place in Burlington, Vermont, in June 2017. He had recently noticed that the American Institute of Architects (AIA) has a Code of Ethics and was aghast at how little was being expected of AIA members,... Read more

Upgrading our basement dehumidifier

September 21, 2018

The basement of our well-insulated and air-sealed 100+-year-old home is dry, but enough moisture (as vapor) makes its way through our concrete walls and slab that dehumidification is a must from about April through October. Dehumidification comes with a pretty big energy penalty, so I am proactive in managing this load: when I see that... Read more

Step-by-step guidance helps design teams put healthier material selection into practice on every project.

September 10, 2018

Awareness of material transparency and hazardous chemical avoidance has increased dramatically over the past several years. But awareness is only half the battle. In practice, selecting building materials that are safer for people and the planet can still be a highly complex and difficult task.

In response to this issue, the American... Read more

Integrating low-temperature hydronic distribution with air-to-water heat pumps provides a more comfortable and “future-proof” heating system for residential and light commercial applications.

September 10, 2018

Hydronic systems, which use water to move energy, are one of the most efficient ways to heat and cool buildings. Water carries far more energy than air, and does so in a small pipe rather than in leaky, bulky ductwork. It can also be engineered to deliver personalized heating or cooling to individual rooms. Many of the hydronic systems used in... Read more

Building materials emit massive amounts of carbon long before the lights go on. Here’s how thoughtful design can reduce global warming impact.

September 10, 2018

Climate change is a rapidly escalating emergency, and we have a lot of hard work to do in order to mitigate its effects. For building professionals, that has typically meant increasing energy efficiency and pushing for renewable energy production, thus reducing the amount of carbon generated by the fossil fuels we burn in order to...

An exhaustive plant-by-plant study reveals the toxic impacts of producing chlorine for PVC, polyurethane, epoxy, and polycarbonate.

August 23, 2018

Chlorine is a problem. Used in many industrial processes, including the production of PVC and other plastics, it readily combines with other compounds to form persistent, bioaccumulative toxic chemicals (PBTs). These chemicals are not only toxic but also highly mobile in the environment and don’t break down readily.

The green building... Read more

Energy, water, waste, and operating costs were all lower in buildings targeting higher performance, according to a new study.

August 6, 2018

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

It will take intensive collaboration across sectors to change an industry and get us safer, better products.

August 6, 2018

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

Shaw is now offering biobased and recycled PET resilient flooring options for commercial and healthcare applications.

August 6, 2018

If you want to avoid vinyl, there are plenty of resilient flooring options available, including rubber and linoleum. But PVC-free flooring can be a challenge to integrate into projects because it is typically expensive, and in some cases its durability or environmental credentials may not even be that great. Some rubber flooring, for instance,... Read more

Recent large-scale projects highlight the beneficial intersections between modular prefabrication, wood construction, and Passive House design.

August 6, 2018

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

Designers asked for transparency and got it. Now they need to follow through with specs, say producers.

August 6, 2018

Five years ago, about 40 prominent architecture firms issued a demand to manufacturers: tell us what’s in your products. They got transparency documents for thousands of product lines in return, according to 35 signatories to a recent letter, and now it’s time for those architecture firms to follow up with “demand” in the economic sense of the...

How the accumulation of dust, pollen, and bird droppings affects the energy production of a PV array

July 10, 2018

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

Lighting is an essential element in quality environments that support health and wellness while reducing energy use.

July 9, 2018

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.
