A new initiative helps solve problems that arise between utilities and their customers when electricity users are also electricity suppliers.

November 5, 2018

Getting a solar array on your project might seem like a huge triumph, but there could be a downside. Too much “distributed generation” (grid-connected power generation coming from individual buildings) can disrupt how the electrical grid works, causing problems for utilities. A new initiative called Grid Optimal from the New Buildings Institute... Read more

For real this time?

October 22, 2018

For twenty years or so, companies like Pilkington (Spacia) have been cranking out R-5ish (center-of-glass) vacuum-insulated glazing (VIG). The attraction of glazing units with a very thin profile, relatively low weight, and a high level of performance is strong, particularly for retrofit applications.

But it sure seems as though we have... Read more

The resilient design pilot credits were taken down temporarily but have returned—with a few changes.

October 10, 2018

Three newly revived pilot credits offer project teams the option of using resilient design to gain LEED points. Pilot credits are a way for users to test out new concepts and achieve points under the Innovation category of the LEED rating systems.

The basic structure of the suite of credits has not changed: the first credit involves an... Read more

The carbon that’s emitted when we produce materials and construct our buildings is finally getting the attention it deserves.

October 9, 2018

Shortly after the release of Paula Melton’s Spotlight Report on Embodied Carbon, which has been getting amazing reviews and kudos, I sat in on an update by Ryan Zizzo, Chair of the Embodied Carbon Network’s Buildings Taskforce. I was so inspired by the breadth of activities suddenly going on in this space, that I decided to lay them out in a... Read more

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

California has committed to 100% “carbon-free” energy by 2045, illuminating the vision promoted by the Global Climate Action Summit.

October 8, 2018

On September 10, 2018 at the Global Climate Action Summit in San Francisco, Governor Jerry Brown signed bill SB 100 into law, committing the state to 100% carbon-free utility electricity by 2045. (California is the second state after Hawaii, in 2015, to commit to 100% renewable energy by 2045.) Two days later at the summit, Brown signed an... Read more

Curbing the urban heat-island effect and managing rainwater are among the strategies that could help cities save big.

October 8, 2018

Solar power, cool roofs, and permeable pavement aren’t new ideas—but they’ve also never been deployed at scale. A new study looks at what might happen if they were.

“Cities mismanage their two great natural gifts of sunshine and rain,” states the report, “Delivering Urban Resilience,” which was supported by the Smart Surfaces Coalition... 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

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

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

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...

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

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

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

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
