From The Editor
As energy codes get more stringent the focus has shifted somewhat from adding more insulation to identifying and eliminating "weak points" in the building envelope. Solutions to thermal bridges, which allow for greater heat flow through the envelope, are the focus of the first article linked below. It is interesting to note that some of the solutions marketed as thermal breaks to reduce thermal bridging actually increased heat flow. Careful evaluation and more research on thermal bridges and thermal breaks is needed, as is holistic evaluation of building energy use. Studies have shown that energy savings can often be maximized by focusing on electrical and mechanical equipment efficiencies.

Illinois Led the Way in LEED Green Building in 2018
Illinois topped the U.S. Green Building Council's list of Top 10 States for LEED for the first time since 2015, with 172 LEED-certified green building projects in 2018. Massachusetts, Washington, New York, Texas, Colorado, Hawaii, Virginia, California and Maryland rounded out the top 10.
 
How to Approach the Dynamic Green Certifications Landscape
METROPOLIS MAGAZINE ONLINE
Setting company-wide sustainability targets, learning the history and purpose of sustainable building standards, and choosing the most appropriate standard for each project are the keys to navigating the ever-expanding green certifications landscape, Audrey Gray writes in this article. Choosing not to get certified is also an option, as in the case of a dormitory project under construction at Bilkent University in Ankara, Turkey, that uses superinsulation and leverages the site's natural breezes to achieve energy efficiency.

Dutch Architects Building Concrete Block 'Open Plan' House for Entire Family Tree
Dutch architects BETA have completed the construction of their "3 generation house" for an entire family in the city of Amsterdam, in the Netherlands. The structure, which is mostly composed of concrete masonry, concrete and glass (windows), is the answer to a design challenge: develop a building for a household comprising of a young couple, their parents and grandparents. The result is a mini-apartment that facilitates adaptation over time for changing spatial requirements. To read and see more, click here.
 
S-Squared's Concrete 3D Printer Could Revolutionize Construction
THE LONG ISLAND ADVANCE 
S-Squared 3D Printers has introduced a concrete 3D printer that can produce a 1,490-square-foot home designed to last a century in just 36 hours at the fraction of the cost and using sustainable materials and practices. Structures built with the system can withstand many tornadoes and hurricanes and are resistant to fire and mold, according to chief safety officer Sal Pane. Read more.
 
Sunconomy Introduces First Leasable, Permitted 3D Printed Home Tech
CURBED (Austin, TX)
To widen the availability of 3D printing in construction, Sunconomy has partnered with residential developer Forge New to introduce We Print Houses, the first 3D-printing home system that can be leased and licensed by builders and contractors. The system can produce energy-efficient, disaster-resistant, low-maintenance concrete residences in "a matter of weeks," and the construction on the first home will begin in February in Lago Vista, Texas according to this article
 
CASE STUDIES
One of the enduring benefits of masonry is its longevity. Adaptive reuse projects blend the appeal of the old with benefits of new construction. The link below showcases one example in NYC.ASTM E 3069 Standard Guide for Evaluation and Rehabilitation of Mass Masonry Walls for Changes to the Thermal and Moisture Properties of the Wall can be a useful tool for evaluating the multiwythe masonry walls common in this type of construction. ~Tina
 
Empire Stores Reimagines Historic Masonry Warehouses
ARCHITECTURAL RECORD
Overlooking a small cove off the East River in the shadow of the Brooklyn Bridge, a group of four- and five-story former warehouses, built in 1869 and 1885, respectively, had been languishing for over half a century, vacant and disused. Now, nearly 150 years since their construction, the Empire Stores, as they were called, are thriving again as an integral part of New York’s Dumbo neighborhood and the waterfront development in Brooklyn Bridge Park (record, January 2011). A thoughtful intervention by Studio V Architecture and S9 Architecture not only maintains the integrity of the existing structures—designated New York State landmarks in 1978—it knits them into a single entity, transforming the 350,000-square-foot timber and masonry facility (once largely used for warehousing coffee) into a lively blend of commercial and public spaces that includes a 100,000-square-foot roof addition, 50,000 square feet of green roofs, and a 7,000-square-foot extension of the park that climbs to the roof.
