BuildingGreen Report

As I’ve stepped back from BuildingGreen in recent years, I’ve shifted more of my time and energy to restoring ecological balance to the Dummerston, Vermont, property where my wife, Jerelyn, and I live. This has meant doing battle with a wide variety of invasive plants—especially oriental bittersweet, Japanese barberry, bush honeysuckle, glossy... Read more

Per- and polyfluoroalkyl substances (PFAS) are used as dirt and stain repellants and are found in carpet and textile treatments, coatings, sealants, and other building and consumer products. They are persistent in the environment, and some are known persistent, bioaccumulative toxicants (PBTs), yet the extent of their use is not fully... Read more

With racial equity coming into greater mainstream focus as a sustainability imperative, one question keeps coming up for building professionals, policymakers, and residents of communities affected by development: how do we move forward?

NAACP is offering answers. The group’s first publication in a series called Guidelines for Equitable... Read more

Reading BuildingGreen’s provocative “Net-Zero Energy Isn’t the Real Goal: 8 Reasons Why” sparked a lot of emotions and thoughts—ranging from strong agreement to a fair amount of “Yes, but….”

Zero energy by itself has never been the full, holistic goal—which instead perhaps is best stated as: “to reconstruct... Read more

We’re not far from the day when we will be able to walk into a building and test indoor air quality in real time from our phones, most experts say. The demand for this air-quality information continues to grow, especially in the wake of COVID-19 and the realization that good IAQ is linked with lower transmission risk. In the... Read more

Disclaimer: BuildingGreen is a technical advisory partner to mindful Materials.

When you think of mindful Materials (mM), you may think of stickers. That’s how the whole thing got started: HKS developed binder labels meant to help its designers quickly identify products in their product library that had transparency labels like health... Read more

The U.S. General Services Administration (GSA) has established two new task groups relating to its large portfolio of buildings—the Federal Building Decarbonization Task Group and the Environmental Justice and Equity Task Group. The moves came in response to a sweeping executive order on climate and environmental justice.... Read more

Net zero-energy (NZE) projects are a big step in the right direction, but we must start designing and operating them differently to accelerate the transition away from carbon emissions in the building sector.

In this report we list eight ways that NZE projects miss the mark on climate goals, including how they affect the electricity... Read more

Karina Hershberg’s transition from focusing on energy to focusing on carbon began six years ago. An electrical engineer at PAE Consulting, Hershberg was working on a project with deep sustainability goals. Net-zero energy (NZE) was a given. The team was considering taking the project entirely off grid and was thinking about a 300-year time... Read more

With drought conditions continuing in much of the U.S., reducing water consumption is an ongoing priority and has made low-flow appliances a necessity. Commercial toilets in particular use a lot of water, requiring a gravity assist to move waste along pipes. Though there are some extremely low-flow toilets available, there is... Read more

Even as the popularity of mass timber increases, sourcing Forest Stewardship Council-certified (FSC) wood is becoming more difficult, especially in certain regions of North America. It’s hardly good for the material’s carbon footprint to ship cross-laminated timber (CLT) and other members all the way across the U.S. or Canada... Read more

“You can probably feel each other’s breath on you.” Renee Weeks is a social worker providing services for people experiencing homelessness at Upper Valley Haven in White River Junction, Vermont. Her empathy for guests comes through while she tries to imagine what it’s like to share cramped sleeping quarters with a stranger. “I... Read more

Per- and polyfluoroalkyl substances (PFAS) are persistent, bioaccumulative, and linked to a number of negative health and environmental impacts. Some forms are toxic and possible carcinogens. These “forever” chemicals are now found on every continent and in the most remote places on the world. They are also common in the... Read more

Katerra—a “vertically integrated” manufacturing, architecture, and construction company specializing in offsite construction—is shutting down its U.S. operations, according to reports from employees, who were alerted on June 1, 2021. Katerra was also a supplier of Forest Stewardship Council-certified mass timber components, and its shutdown... Read more

A zero-carbon building sector by 2050. We know we need to hit that target, but getting it done will require new insights, new products, new policies, and new funding.

“Many organizations that work with us have set corporate-wide greenhouse gas, renewable, or carbon goals,” said Maria Vargas, senior program advisor at the U.S. Department... Read more

Many K–12 schools have raced to improve indoor air quality (IAQ) during the COVID-19 pandemic, but major barriers remain, according to a report released by ASHRAE and The Center for Green Schools. These include aging HVAC systems. But help may be on the way in the form of billions in relief funding from the federal government... Read more

It’s award season for major architectural prizes: the American Institute of Architects’ (AIA) Gold Medal and the international Pritzker Architecture Prize. These are considered the highest honors for an architect. The goal of the Pritzker Prize is “to honor a living architect or architects whose built work demonstrates a combination of those...

We now know that filtration and ventilation are key to reducing the risk of spreading COVID-19. But how do you know how much is adequate, and exactly which steps to take to improve?

The World Health Organization (WHO) recently released its “Roadmap to improve and ensure good indoor ventilation in the... Read more

The themes of Living Future ’21 were unmistakable: a strong call from leaders in the building professions for allyship around justice, equity, diversity, and inclusion (JEDI).

A few important ways to do this stood out:

An act of violence.

That’s how architect Anne Lacaton describes building demolition. Lacaton and Jean-Philippe Vassal, who have vowed to never tear down a building, have won 2021’s Pritzker Prize—an award often described as the equivalent of a Nobel Prize in architecture. Even when they build new, the... Read more
