Interest in embodied carbon is growing. Here’s a guide to the tools that can help you measure and reduce these emissions on projects.

September 9, 2019

Awareness and concern about embodied carbon—the upfront greenhouse gas (GHG) emissions associated with producing building materials and constructing a project—has skyrocketed recently. Building professionals and owners alike want to assess and reduce the embodied carbon footprint of their projects in order to cut their near-term emissions (see... Read more

Primer

With more owners looking to reverse the embodied carbon impact of their buildings, it’s important to know how to buy legitimate offsets.

September 9, 2019

What if you could write a check to magically cancel out your carbon footprint?

Actually, you can: that’s the whole idea behind carbon offsets, which building owners can purchase in order to negate their greenhouse gas emissions. Carbon offsets can be used to make up for either embodied carbon (the emissions associated with construction... Read more

Sixty percent of people in a USGBC survey identified recycling as one of the top three ways to help the environment. Only 7% chose “Live in a green building.”

September 9, 2019

U.S. residents are concerned about the future state of the environment, but they’re not doing much about it. They also don’t see green building as part of the solution.

These were some of the conclusions of a recent study commissioned by the U.S. Green Building Council (USGBC) and conducted by ClearPath Strategies. Part of the new “... Read more

Offsite modular construction not only cuts costs and construction times but also benefits people and the planet.

September 9, 2019

The modular construction approach—in which a building’s large-scale modularized components are prefabricated in an offsite manufacturing facility for rapid assembly onsite—is garnering an increasing amount of attention in the building industry. This is due in large part to the interrelated issues of the rising costs of traditional construction... Read more

In California, rice straw is replacing wood as a raw material in medium- and high-density fiberboards while making use of an agricultural waste product.

September 9, 2019

Agricultural fiber (agfiber) boards made from wheat straw seem like a great idea. They replace wood—a valuable commodity—with a waste product from agricultural production. In the late 1990s, these wheat straw-based panels found a brief market niche for use as a particleboard replacement in cabinetry, but manufacturing challenges, costs, and... Read more

CL-Talon provides a cladding system that can incorporate up to ten inches of insulation and comes with thermal breaks and easy-to-adjust framing.

August 6, 2019

Thermal bridging, where thermal energy finds pathways from the outdoors through the building envelope, is the Achilles’ heel of rainscreen systems. The reason: exterior cladding has to be mounted to the building, and this typically requires clips or screws that have to pass through the insulation. The clips not only create a thermal bridge to...
