Materials in Action - Examining the Impacts of Building Materials Think Wood
When an architect specifies a building material, that choice casts a long shadow. While most of the environmental effects from materials occur during the extraction and production phases, they continue to influence a structures' environmental footprint long afterwards, throughout the operations phase and beyond. This presentation evaluates the environmental impact of building materials wood, concrete and steel.
Wood Scores A+ for Schools & Student HousingThink Wood
In educational facilities architects are called upon to achieve a wide range of objectives with limited budgets. An increasing number of designers are turning to wood-frame construction as a reasonable solution, it typically costs less while meeting all code and safety requirements. In addition, wood-frame construction offers advantages such as speed of construction, design versatility, and a light carbon footprint.
Cost-effective, code-compliant and sustainable, mid-rise wood construction is gaining the attention of design professionals nationwide, who see it as a way to achieve higher density housing at lower cost—while reducing the carbon footprint of their projects. Yet, many familiar with wood construction for two- to four-story residential structures are not aware that the International Building Code (IBC) allows wood-frame construction for five stories and more in building occupancies that range from business and mercantile to multi-family, military, senior, student and affordable housing. This presentation reviews the benefits of multi-story wood construction, the code requirements and discusses the design techniques used in multi-story wood construction.
Wood A Natural Choice - How the Building Material Contributes to Sustainable ...Think Wood
This presentation contributes to the discourse on sustainability that is driving ongoing improvement in the way buildings are designed and constructed. Specifically, it focuses on the growing trends of wood use as a low environmental-impact building material and the effect green building rating systems have on design choices.
Modern Building Codes: Keeping Pace with the Wood RevolutionThink Wood
There is a quiet revolution
taking place within the design
community. After a long
emphasis on concrete and steel for
buildings other than homes, design
professionals are using wood to great
effect in a growing number of nonresidential
and multi-family building
types—in applications that range
from traditional to innovative, even
iconic. Some are driven by wood’s
cost effectiveness, while others cite
its versatility or low carbon footprint,
but their collective path has been
made possible by building codes that
increasingly recognize wood’s structural
and performance capabilities, and the
continued evolution of wood building
systems and techniques.
Wood in Buildings: Steps to Durability and LongevityThink Wood
Architects specify wood in their building designs for many reasons, including: cost, availability, ease of construction, thermal performance, aesthetics and design versatility. Research and new product development have only added to the versatility of building with wood. This presentation reviews how to use wood to its full potential. It discusses wood’s advantages in durability and longevity, while explaining issues of quality control for wood construction and the architect’s role in promoting such control. Finally, this explains how to maintain wood buildings and maximize performance.

The project features several strategies to integrate sustainable architecture and engineering improvements into a historic structure. We will investigate questions of design strategies, LEED Certification, performance measurement, products and materials, and other critical questions.
Sited on the main historic quad of the campus, the building was constructed in 1929 and has been housed in the Earth Science and Natural Resources programs since 1970. Interweaving the retention and restoration of existing materials alongside new efficient technologies, the rehab and expansion included refinishing existing windows, implementing high-performance envelope strategies, and shoe-horning ventilation within the existing shell. The HVAC systems included both chilled beams and highly efficient energy recovery systems.
The collaborative and integrated team included UNH Department of Facilities Design and Construction, EYP Architecture and Engineering, Le Messurier and Shawmut Design and Construction. This roundtable is part of the Sustainable Design Case Study Series at NEXUS. Learn more at http://www.nexusboston.org/news/casestudyroundtables.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Completed: 2013
The design team mixed cost-effective
wood framing with a sleek,
contemporary exterior for this luxury
mixed-use development. Because
they had limited room on site, they
pre-framed the wall panels, which the
developer said saved “a few hundred
thousand dollars just in general
conditions and supervision.”
Adding to the savings, the framer
says panelization typically takes 10 to
15 percent off the timeline compared

Often, even when wood is chosen to meet other goals, cost is still the deciding factor. For the Marselle Condominium project in Seattle, Washington, wood construction helped the building meet requirements of the local Master Builders Association Built Green program. But while the environmental recognition was an added benefit, the developer considered the decision to use wood framing purely financial.
“If the project had been built using all concrete, for instance, it would have cost about 30 percent more,” according to Kory Knudson, vice president of Norcon, NW, Inc. “If we had built the entire project out of steel, it would have taken much longer and we would have had to make many energy modifications.”

One of the keys to Stella’s success was coordination. With limited room on site, the developer, GLJ Partners, hired the framer to begin working on the wall panels about eight months prior to construction, which GLJ estimates “saved a few hundred thousand dollars just in general conditions and supervision.”
Adding to the savings, the framer says panelization typically takes 10 to 15 percent off the timeline compared to traditional site built construction. If there hadn’t been delays with the podium, he says the Stella could have been entirely framed in 20 weeks, which is fast for a building of its size and level of complexity.

Wood-frame schools can be easily designed to meet and exceed the demanding energy efficiency requirements of environmentally-minded school districts. And, they can do so cost effectively. One of Bethel School District’s new elementary schools, completed in 2011, had a total construction cost of $197.70 per square foot—a significant savings compared to the average construction cost of an elementary school in western Washington, which is $250.07.

Building codes recognize wood’s structural performance capabilities in a broad range of applications—from the light-duty repetitive framing common in small structures to the larger and heavier framing systems used to build arenas, schools and other large buildings.
However, around the world, architects and structural engineers are extending the boundaries of wood design, while innovative technologies and building systems continue to expand opportunities for wood use in construction. It’s a symbiotic relationship that has also influenced the evolution of building codes and standards

In addition to cross laminated timber (CLT), parallel strand lumber (PSL), glued laminated timber (glulam) and prefabricated paneling systems are among the products contributing to a wider range of wood buildings. They have made wood a viable choice for applications such as arenas, gymnasiums and lobbies, which require tall walls and large open spaces with minimal, intermediate supports.

The IBC allows wood-frame construction for five stories and more (e.g., with the use of mezzanines and terraces) in building occupancies that range from business and mercantile to multi-family, military, senior, student and affordable housing. However, there are indications that this may increase as new products continue to enhance wood’s ability to add value in multi-story applications. For example, cross laminated timber (CLT) is widely used in Europe and is gaining ground in North America.

As trees grow, they absorb carbon dioxide from the atmosphere. They release the oxygen and incorporate the carbon into their wood, roots, leaves or needles, and surrounding soil. One of three things then happens:
• As trees mature and then die, they start to decay and slowly release the stored carbon back into the atmosphere.
• The forest succumbs to wildfire, insects or disease and releases the stored carbon quickly.
• The trees are harvested and manufactured into forest products, which continue to store much of the carbon. In the case of wood buildings, the carbon is kept out of the atmosphere for the lifetime of the structure— or longer if the wood is reclaimed and manufactured into other products. Wood stores more carbon than is emitted during its harvest, production, transport and installation.
23.
According to the U.S. EPA Greenhouse Gas Equivalencies Calculator, estimated carbon benefits for the five-story Avalon Anaheim Stadium equate to a year’s worth of emissions from 2,370 cars, or the energy to operate an average home for 1,050 years.
24.
Wood has low thermal conductivity compared to steel and concrete. As a result, wood is easy to insulate to high standards while steel and concrete must overcome problems from thermal bridging and the possible consequence of moisture condensation on cold surfaces.
However, because there are many factors that have a greater influence on a building’s energy efficiency (such as insulation and air tightness), the more relevant point for many designers is that wood building systems lend themselves to structures that are highly energy efficient—with less impact on the environment in terms of embodied energy, air and water pollution, and carbon footprint.
Any wood structural system can be designed to achieve a tight building envelope. However, with new systems such as CLT, precise manufacturing results in tight tolerances and exceptional air tightness. The added aspect of dimensional stability also ensures that the building remains airtight over time.
25.
The “Survey on Actual Service Lives of North American Buildings” showed that buildings in the U.S. often have a service life of less than 50 years, regardless of material, because of changing needs or increasing land values as opposed to performance issues.
When one considers the embodied energy in these structures and issues related to disposal, the adaptability of wood structures and building systems, either through renovation or deconstruction and reuse, is a significant advantage.

The Seattle District headquarters for the U.S. Army Corps of Engineers is a LEED Gold-certified project. All of the wood used was salvaged from a 1940s-era warehouse that previously occupied the site—a total of 200,000 board feet of heavy timber and 100,000 board feet of 2x6 tongue and groove roof decking. The heavy timber is featured fully exposed in the central commons, which includes conference rooms, libraries, restrooms and gathering areas. However, because the amount of reclaimed wood was limited, composite timber-concrete beams were also used to increase beam spacing and allow the entire program to be met with wood from the warehouse. Heavy timber was also used on the walking surfaces of interior pedestrian bridges and stairs, incorporated into the exterior
entry canopy, and milled for use as hand railings and ceiling finishes, while reclaimed decking was also used for interior wall paneling.

People feel an instinctive connection and attraction to natural materials, and many building designers cite the warm attributes of wood as a reason for its use. Evidence also suggests that exposed wood can contribute to an individual’s sense of well-being. In an office or school, wood is thought to improve performance and productivity; in a hospital, it may have a positive impact on patient recovery.
A study at the University of British Columbia and FPInnovations found that the presence of visual wood surfaces in a room lowered activation of the sympathetic nervous system (SNS). The SNS is responsible for physiological stress responses in humans such as increased blood pressure and heart rate while inhibiting the parasympathetic system responsible for digestion, recovery and repair functions in the body.5

The Thunder Bay Regional Health Sciences Center in Ontario was the first hospital in Canada to gain approval for the use of wood as a primary structural element. Featuring a dramatic three-story wood and glass walkway, the structure incorporates over 1,100 glulam members, some more than 65 feet long. The use of wood extensively throughout the structure provides a bright and optimistic atmosphere for patients, staff, and the community.
30.
Wood was used extensively in this 49,000-square-foot LEED Platinum, net zero energy company headquarters, emphasizing the building as a healthy and sustainable place to work. By combining exposed wood inside with views to the outdoor courtyard, the architect created a relaxed environment where the occupant is in constant contact with nature.
31.
Given the 26,000-square-foot Robinson Nature Center’s role of connecting visitors with nature, it was important that the structure appear modest on approach and in keeping with its setting, while minimizing impacts on the site. Achieving LEED Platinum certification was of paramount importance to the client as its mission is to educate the public about environmental stewardship. By specifying wood that was either FSC-certified, low-emitting, recycled and/or regionally produced, seven LEED points were gained, helping this goal to be met.
32.
With growing pressure to reduce the carbon footprint of the built environment, building designers are increasingly being called upon to balance functionality and cost objectives with reduced environmental impact. Wood can typically help to achieve that balance.
