SPONSORED EDITION
From the Editor
As I write this I have recently returned from the Winter Meetings of the project committee (SSPC) for ASHRAE Standard 189.1 on high-performing green buildings. As I've noted in this newsletter before, the SSPC decided in 2018 to undertake a restructuring of the standard to create two tiers, "core" and "above-core" provisions. The work to make this happen began in earnest at the meetings when each of the Work Groups recommended sections of ASHRAE 189.1-2017 to be marked as "above-core". Look for them to be published as addenda for public comment in the coming months.

One of the goals of sustainable design is to create buildings that do not just tread lightly on the land but are restorative as noted in the articles below. ~Tina
 
Concrete Block Building Helps Cure Depleted Hawaiian Soils
ARCHITECTS NEWSPAPER
The Los Angeles offices of Perkins+Will and Hawaii-based KYA Design Group have completed work on a new health-focused administrative complex at the University of Hawaii, West Oahu, that, among other things, works to replenish and nurture the site's depleted, post-agricultural soils. The multi-gabled, masonry-clad complex is inspired by vernacular sugar mill structures and stretches across an open site that was once used to grow sugar cane. The site's rich soils became depleted after a century of aggressive cane farming, a process that leeched nutrients, organic matter, and topsoil from the site. Read morehere.
 
Commentary: AEC Industry Needs Greater Climate Change Accountability
REAL ESTATE WEEKLY (New York City)
The architecture, engineering and construction industry must begin to take responsibility for its effects on the environment, Gunnar Hubbard writes. Reliable guidelines for sustainable design and construction must be developed, and net-zero energy consumption is a worthy goal that comes with economic benefits, he says in this article
 
 
CODES and STANDARDS NEWS
As we noted in our last edition, LEED v4.1 is available for all LEED rating systems. Check out the links below for some useful resources. ~Tina
 
New Guidelines Can Help Communities With Resiliency Measures
BUILDING DESIGN + CONSTRUCTION
The International Code Council and the Alliance for National and Community Resilience have developed the first resiliency guidelines, which local communities can use to improve buildings codes. "These benchmarks provide a standard for local and state governments to follow ensuring they are well prepared for the next disaster," ANCR Executive Director Ryan Colker says in this article.

Commentary: Green Building Materials Drive Sustainability Efforts
BUILDING (U.K.)
Developing environmentally friendly building materials and greener concrete solutions is the key to reducing the construction industry's carbon footprint and meeting bold sustainability targets, writes Barry Mellor of Aggregate Industries. For example, replacing quarried natural aggregate in the concrete mix with secondary aggregates could slash carbon emissions in buildings by up to 10% and make concrete 50% lighter, he says.
 
Super Tensile Building Block Could be Terror's Kryptonite
THE CONSTRUCTION INDEX
Tarmac, a producer based in the United Kingdom, says they've developed a building block that uses a super tensile constitution -- almost elastic -- to make it virtually indestructible when faced with violent techniques weaponized during a terror attack, namely bullets and explosives. It's called the BBX construction system, & it boasts blast resistance coupled with ballistic resistance. While its makeup is similar to concrete block, in lieu of stone aggregate it contains "bespoke materials" which give it its unique stretchy, resilient capability. To read more, click here.
 
Builders Without Borders Introduces Small Tool That Measures Concrete Block Strength
DAILY COMMERCIAL NEWS
At the recent The Buildings Show in Toronto, Builders Without Borders Director Brian Palmquist discussed lessons learned when rebuilding communities around the globe -- one of them being concrete testing. In doing so, he introduced a brand new, practical handheld tool that makes it easier than conventional methods to measure the strength of concrete block. It's also a lot less expensive and doesn't ruin the block. The apparatus, called NDART (non-destructive acoustic resonance testing), looks like a metal ball on a wire. You swing it, the ball hits the concrete block or cylinder and, using an app on a smartphone, and it provides a reading. Four things have been calibrated so far: two standard concrete block sizes and two different sizes of standard cylinder. Read more
