This is Part One of a two-part series related to affordable housing. It emphasizes the critical importance of sustainability in affordable housing and details six steps building professionals can take to help that happen. Part Two supports project teams across disciplines and building typologies with 12 specific ideas for building green on a... Read more

Note: This guide does not include information on boilers or air-to-water heat pumps used in larger commercial applications, though some HPWH systems are modular and can sometimes meet those demands.

Heat-pump... Read more

The commercial water-heating systems used in hotels, restaurants, and large multifamily buildings have a few problems. As we move toward all-electric buildings, we need an alternative to gas, but heat-pump water heaters face a couple of challenges:

Wood products are widely considered to be inherently “carbon neutral.” The current surge of interest in mass timber was spurred by this belief.

But could scaling up our demand for wood actually make climate change worse?

It’s a huge risk. Our forests are a massive carbon bank and a critical climate buffer,... Read more

It’s here. So what’s new?

The U.S. Green Building Council (USGBC) released LEED v5 for its first public comment period on April 3, 2024, giving us our first detailed look at the next generation of the program that has defined green building in North America and around the world for more than... Read more

As the 2024 event season approaches for BuildingGreen’s Peer Networks, the Sustainable Design Leaders (SDL) have been looking forward to yet another summit at the beloved IslandWood venue on Washington’s Bainbridge Island.

But in the aftermath of Paula Melton’s two-part report released earlier this year, “Wood: Is It Still Good?” it’s... Read more

“I was specifying ground-source heat pumps before they were popular,” recalled Gea Snootfeld, principal at Seattle’s Maverick Design. “Most people installing them now don’t, like, actually, get it.”

Snootfeld is referring, of course, to the recent breakout of ground-source heat pumps (GSHPs) onto the mechanical heating and cooling... Read more

Welcome to the second installment of BuildingGreen’s Biophilic Design series “Built Against the Howling Wind,” as we follow the Boar brothers’ journey of sustainable homebuilding from design considerations through project completion. We’ll look at the choices and challenges that triplets Kevin, Wilbur, and Hamlet ran into while selecting... Read more

Long before Sharknado, far in advance of Shark Week, popular culture produced something historians have since dubbed “the best marine-animal metaphor since trained seals.”

Yes, we mean jumping the shark—a type of ridiculous stunt that heralds the imminent decline of a formerly respectable endeavor.

Experts now say this metaphor... Read more

As the morning sun hits the east-facing curtain wall, Summit Ridge Office Park gazes down at its own reflection in the still waters of a man-made lake. Until recently, the building simply accepted what it saw there: a six-story, highway-adjacent office complex, first built in 1987. Once proud of its blandly handsome exterior, Summit Ridge...

Nonconformist, bohemian businesses in Vermont share a long-held footwear philosophy: “no shoes, yes service.”

And similarly, but also really differently, shoelessness has found a foothold among companies in southern California’s famously informal—even wacky—tech start-up scene.

“I love to scrunch the course carpet nodules... Read more

In a surprise move aimed at reducing the carbon impacts of commuting, Houston, Texas is banning cars from most of the city limits, expanding bicycle infrastructure into the suburbs, and even making right turns illegal. Mayor John Whitmore said residents overwhelmingly supported the initiatives in recent elections, and local businesses are... Read more

There’s no question that overinflation comes with hazards aplenty—ever since Professor Michael Faraday... Read more

Standard outdoor lighting is left on for long hours and is often too cold a color; it also allows light trespass that disturbs people, wildlife, and ecosystems.

The best lighting is “efficacious” (... Read more

Grinders’ asthma. Stonecutters’ consumption. Potters’ rot. Silicosis.

Lung disease from breathing in dust is one of the oldest and most lethal occupational hazards for people working in the building trades. According to a “A Short History of Occupational Disease,” an article published by the Ulster Medical Society in 2021, evidence of... Read more

This is Part Two of a two-part series on wood products. Part One focuses on the embodied carbon of wood products, exploring the origin and veracity of industry carbon-neutrality claims and considering the avoided emissions associated with using mass timber in place of structural steel or concrete. Part Two considers broader climate implications... Read more

Everyone wants to save water, but low-flow shower units have been faulted for delivering poor performance—leading people to spend more time in the shower or to remove the showerhead and replace it with an older, higher-flow showerhead.... Read more

Are wood products inherently carbon neutral?

Many people think they are even better: “net carbon storing,” or “carbon negative.” Because of this, the green building community has hoped that mass timber will drive decarbonization.

But it turns out that scaling that up could make things worse instead... Read more
