April Fools
With the rousing success of the WELL Building Standard, the Green Building Initiative has launched a competing standard that emphasizes occupant comfort, energy savings, and freedom.
There are a number of building standards claiming to improve occupant health and well-being. Costly, complicated certifications such as WELL, Fitwel, and others place an emphasis on promoting “wellness” at the expense of what Americans want most: comfort, convenience, and freedom. A new standard from the Green Building Initiative (GBI), which... Read more

Hanging Gardens offers a “smart” blue-roof system that stores water on roofs, monitoring weather and local stormwater to more effectively manage runoff.
Building owners generally frown upon water pooling on a roof, but with careful detailing, roofs can be a good place to store excess rainwater. Storing water on roof makes sense in urban areas when there is little free space on the lot, or when putting it in the ground is expensive or inappropriate, such as on brownfield sites. These “blue roofs... Read more

Though products are not yet on the market, a state commission has given the go-ahead for select foam insulation without flame retardants or fire testing.
WARNING – FIRE HAZARD.
That’s how plastic foam insulation will have to be marked following a decision by the State of California Building Standards Commission to allow flame-retardant-free products to be used below grade. The boards will also have to say, in ½-inch-high red lettering, “This product is required to be installed below a... Read more

The 4.1 version of LEED’s design and construction rating systems is outstanding. Is it too late?
As Malcolm Gladwell illustrates so well in his bestselling book Outliers, nothing great emerges fully formed. Just ask the inventor of WD-40 about his previous 39 formulations.
LEED 4.1 is such an achievement. The current working drafts of LEED for Building Design and Construction (BD+C) and LEED for Interior Design and Construction (ID... Read more

BD+C and ID+C projects can now register—and v4 projects can already substitute v4.1 versions of credits.
Even though LEED v4 launched more than five years ago, it’s still a “new” rating system to many users. That’s partly because the construction cycle is long, but it’s also due to the fact that registration under v4 wasn’t required until late 2016. But LEED v4 definitely isn’t new anymore: with the beta launch of LEED v4.1 for Building Design and... Read more

In a year of devastating disasters, greenhouse gas emissions rose. Here’s what we can do about it.
By James S. Russell
We’ve just ended a year of fires that killed 85 in California, nearly destroying the town of Paradise, and hurricanes that took 53 lives in Florida and 43 in the Carolinas, leaving thousands of destroyed homes and billions of dollars of damage in their wake. The connection of these and other storms and droughts to... Read more

After years of study and testing, the International Code Council will allow heavy timber buildings taller than 85 feet.
It’s about to get a lot easier to build high with mass timber.
It all started when the American Wood Council (AWC), a trade group promoting the use of wood in construction, approached the International Code Council (ICC) with a request: study tall wood construction. In particular, AWC wanted some scientific rigor brought to the issue... Read more

Alpen is rolling out triple-pane products that are thinner and lighter—and will eventually be cheaper.
The good news about window performance is that the market has been transformed by the building industry moving to dual-pane, low-e, argon-filled glazing with performance around R-4, according to Lawrence Berkeley National Laboratory (LBNL). See Figure 1 in the slideshow.
The bad news is that since around 1990, the performance of the... Read more

The SDL Show-and-Tell session is where Greenbuild becomes more personal, more intimate, less business-to-business, and more community-centric.
The Greenbuild International Conference and Expo is the world’s largest conference and expo centered around sustainable design. Greenbuild is unparalleled in its robust educational and networking opportunities, but it can also be a bit overwhelming. Over the past couple of years, I’ve especially enjoyed a special evening of respite, inspiration... Read more

What began as a group of those pursuing the Living Product Challenge is now a wider platform for community and communication.
It might seem like manufacturers and their representatives are constantly talking to the design community. But the message isn’t exactly unified; in fact, companies are competing for time, attention, and dollars. Is there a way for manufacturers to get together as a group and have productive, two-way conversations with building professionals... Read more

What’s up with all the programs encouraged by LEED and WELL? Learn the essentials—plus what’s behind the labels.
A seal of approval is a useful guide. It lets you know at a glance that a product meets a trusted source’s standards for performance. But in a sea of logos, any particular program becomes harder to discern and understand.
LEED and WELL encourage a number of different product standards, certifications, and disclosures—so many that it’s... Read more

Two-thirds of green certifications and regulations address carbon emissions from building materials—a number that has doubled over the past five years.
The built environment is a major contributor to climate change, and the source of many cost-effective solutions. After operating energy use, embodied carbon in buildings and infrastructure looms large as an important challenge. As BuildingGreen’s recent Spotlight Report The Urgency of Embodied Carbon and What You Can Do about It explains, this... Read more

A reader argues that a flawed study mars the message of a recent BuildingGreen report on embodied carbon.
By Dave Atkins and Sarah Larsen
Paula Melton’s article on The Urgency of Embodied Carbon and What You Can Do About It couldn’t be more timely given the recent Fourth National Climate Assessment and the latest from the Intergovernmental Panel on Climate Change. Embodied carbon is spent immediately, while operational carbon is spread out... Read more
