From The Editor
One of the challenges in the green building industry is program uptake - trying to get designers to design, and owners and contractors to build in a way that is better for the environment and the people that live and work in the buildings themselves. It is a challenge faced by all the various green programs on the market and there are valid reasons for it. LEED's initial success has tapered off in the last few years. The Living Building Institute is challenging for even those dedicated to "green". The International Green Construction Code has only been adopted in a few jurisdictions, and the ASHRAE Standard 189.1 for High-Performance Green Buildings has even fewer users. As a result, all are examining how they can make their programs more widely accessible, adoptable, and used. Several articles under CODES and STANDARDS NEWS discuss the steps these organizations are taking. In the end, whether it's a "scalable' approach (LEED and Living Buildings) or "core" and "above-core" (ASHRAE 189.1/IGCC), the hope is that more buildings will live lightly on the land.

Despite the fact that the first two articles below confuse concrete masonry and concrete, they are great examples of using masonry to provide resilient designs. ~Tina
Ohio school to add reinforced concrete masonry tornado shelter
WSYX-TV (Columbus, Ohio)
Ohio's Fairborn Primary School is building a tornado shelter that will be able to hold 1,200 students inside, reportedly making it the first school in the state to do so. The shelter will have steel-reinforced concrete masonry walls that provide a safe space for students and staff. Read more.
Florida home contractor uses concrete for hurricane resiliency
Delray Beach, Fla.-based Akel Homes offers homes constructed from concrete block to comply with the Florida Building Code requirements for hurricane resistance. The homes also include energy-efficient features and impact-rated windows so "form and function are in complete equilibrium," co-President Alexander Akel says in this article.
Column: The heating, cooling needs of net-zero-energy buildings
Designers of net-zero-energy buildings need to account for a number of factors that affect heating and cooling needs, such as intended occupancy, equipment and the thermal envelope, writes Michael Tobias. HVAC equipment needs to have a high nameplate efficiency to reduce the building's energy consumption and operating costs.
The first article below caught my eye because it expressed a belief I have long held, that glass facades are not energy efficient. Looking at any large city though, you can see this fact does not translate into practice. The likelihood of this legislation passing is probably slim, but it is encouraging to see the dialogue it has inspired. ~Tina
NYC to introduce bill to ban new glass skyscrapers
In a bid to curb New York City's greenhouse emissions by 30%, Mayor Bill de Blasio plans to introduce legislation to ban construction of new glass skyscrapers and require existing glass buildings to be retrofitted based on more stringent guidelines. The plan also calls for powering all of the city's operations with clean electricity. 
Mass. considers net-zero building standard
Massachusetts legislators Tami Gouveia and Joanne Comerford introduced a bill that would require many new buildings to achieve a net-zero energy standard. However, critics such as Byggmeister Design & Build President Paul Eldrenkamp believe that such a policy could have unintended consequences, as owners could construct less-efficient buildings and simply include more solar panels on them. Read more.
What’s next for LEED: V4.1, recertification and LEED Zero
It’s been a little over a year since the U.S. Green Building Council (USGBC) first announced an update to Leadership in Energy and Environmental Design (LEED), the most widely used green building program in the world. What’s new with LEED version 4.1? What are the goals? Melissa Baker, senior vice president for technical core at USGBC, says in this article that the update is designed to equip project teams with the right tools to better understand how their buildings are performing, to demonstrate that all the sustainability goals are met, and to identify areas for improvement. “We wanted to make the rating system more accessible,” Baker says. “Establishing stepping stones, getting people [to use] credits that haven’t had much uptake, where we might have wanted to see uptake. Also, taking the market feedback that we’ve received and incorporating that while maintaining leadership.”
Living Building Challenge 4.0 Meets Market Demand for Increased Scalability
At the Living Future unConference earlier this month, the International Living Future Institute (ILFI) rolled out the latest version of its industry-leading green building standard, the Living Building Challenge 4.0 (LBC 4.0). At the same time, the Institute also released the Core Green Building Certification, and a new Volume Certification program which will make it more efficient for organizations to certify an entire portfolio of projects. Read more.
More on reducing the carbon footprint of concrete (and concrete products). ~Tina
Blue Planet takes a different approach to carbon capture
Blue Planet has developed a carbon capture method that forgoes the usual energy-intensive process of producing purified carbon dioxide and instead uses CO2 as a raw material to make synthetic limestone for concrete. The material has already been put to use at San Francisco International Airport's new terminal and runways. Read more here.
Lehigh Hanson enhances sustainability with PLC
Lehigh Hanson has improved the sustainability of its operations through the introduction of portland limestone cement, or PLC, which reduces carbon dioxide emissions by diverting a portion of limestone past the pyroprocessing stage. "Using PLC and slag may not sound as exotic as some of the other technologies out there, but by far and away it gives you the biggest bang for the buck when it comes to making an actual improvement on your environmental footprint," said Mike Stanzel, Lehigh Cement's technical services manager for Ontario and Quebec in this piece.
