Linoleum’s natural ingredients often make it the best resilient flooring option. Corques Liquid Linoleum is a fluid-applied version for seamless applications.

October 7, 2019

Linoleum is regarded as one of the most sustainable options for resilient flooring, and for good reasons. It’s made from natural materials—typically a combination of linseed oil, pine rosin, wood dust, cork, limestone, and colorants attached to a jute backing. And linoleum is a versatile flooring that has been manufactured in some form for more... Read more

More and more cities are encouraging electrification by regulating natural gas hookups, while other areas face supply shortages.

October 7, 2019

Berkeley, California, started the trend. In July 2019, it outlawed natural gas hookups in new construction. The law will take effect in 2020 starting with single-family homes, and it will eventually apply to all buildings. The primary goal? To completely electrify new buildings as the grid gets cleaner and thereby reduce greenhouse gas (GHG)... Read more

Building professionals push for ways to ensure “slave-free” buildings.

October 7, 2019

Almost 95% of the construction materials used to create any given building come from only 400 to 600 raw materials and 75 to 100 composite building products, according to Grace Farms Foundation. Yet supply chains are so vast and convoluted that they can mask many instances of human exploitation: forced labor, human trafficking, and child labor... Read more

The American Institute of Architects has made its boldest move yet toward declaring great design and sustainable design one and the same.

September 23, 2019

It’s a bold step forward, and The American Institute of Architects (AIA) isn’t shy about saying so. It’s nicknamed the change “the Big Move Toward Environmental Stewardship.”

The move began gradually, years ago, with a “sustainability scan” that took stock of how AIA was foregrounding sustainable design across its... Read more

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

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

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

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

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

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...
