Proposed Session Description
Bowdoin College is building a pair of connected new buildings - Barry Mills Hall, an academic building with a large event space, and the Center for Arctic Studies to house the Peary-MacMillan Arctic Museum and its academic program during a time when the Arctic is experiencing unprecedented warming. In this session, representatives from the HGA design team and the contractor will discuss WHY they collaborated on systems and material selection to align the Center’s mission and the College’s sustainability goals with the building’s design and construction. Speakers will address WHY using mass timber for the primary structure of the buildings benefits the College’s impact on carbon emissions, and emissions in the construction industry as a whole. We will also explore WHY we selected the mechanical systems we did to balance the museum’s need to maintain strict temperature and humidity controls for protection of the collections, while minimizing carbon, maximizing energy efficiency and supporting beneficial building electrification. Attendees will understand WHY leveraging multiple systems in the design process can work together to achieve overall sustainability and carbon-neutral goals, while advancing the museum’s mission and values and aligning with the academic institution’s messaging about sustainability and responsible stewardship of the Earth.
Diversity and Inclusiveness
Our moderator and speaker roster includes four presenters from a large architecture and engineering firm located in a metropolitan area: a woman who is a mid-career design architect, a man who is a mid-career architectural project coordinator and sustainability specialist, a man who is mid-career mechanical engineer and sustainability specialist, and a woman who is an early-career structural engineer. The other speaker is a man who is a director of operations for the Maine office of a leading construction manager and general contractor serving clients throughout the northeast. This session topic addresses economic justice, particularly for Maine’s rural communities.
Learning Objectives
Participants will learn how carbon neutrality in new building design can be achieved through multiple design disciplines.
Attendees will witness how a college and its arctic studies museum is aligning its core educational and research mission on climate, environment, and human activities.
Participants will understand WHY mass timber is a viable structural option for museums, offering a multitude of benefits, including natural fire resistance, strength comparable to steel and concrete, shorter construction schedules and a neutral carbon footprint, and the tools that can be used to demonstrate these benefits.
Attendees will understand how museum-level temperature and humidity requirements can be met while balancing sustainability goals.

Full Description
This session will get at WHY the use of mass timber compliments Bowdoin College’s commitment to environmental responsibility - from design through construction and operation. However, past attempts to pursue mass timber construction on campus have failed due to the perceived costs associated with a relatively new and unknown technology, as well as the lack of regional suppliers and manufacturers. This project will support Bowdoin’s institutional goals for carbon neutrality and sustainable practices. Beyond this, the project will be a model for the viability of mass timber in the northeastern United States building market – suggesting a promising trajectory for Maine’s forest industry. Through the use of mass timber in this project, the College hopes to push the conversation of sustainability and carbon footprint beyond an operational analysis and into an awareness of material choices and the impact of embodied carbon and energy. For an embodied energy and carbon evaluation and comparison, Life Cycle Assessment (LCA) was used to compare structural systems of concrete, steel, and mass timber. The LCA identified that mass timber has negative embodied carbon and therefore a positive impact on the overall embodied carbon in the project. For a cost competitive evaluation and comparison, two structural systems were considered: a structural steel framed floor and roof system with metal deck and cast in place concrete slabs in contrast with a system of glue laminated timber beams and columns with cross laminated floor and roof systems. Historically, attempts at modeling cost savings and comparing systems only focused on the direct costs of those systems. For this project the evaluation of the two systems was initially compared for upfront costs. However, unlike typical cost models, the cost comparison for this project explored how schedule, and more importantly, weather conditions, affect the costs of each option. A risk-based analysis was used to explore how winter conditions are evaluated by incorporating weather data and probability-based decision making into the model. This “4D modeling” method was used to evaluate the cost and schedule of both systems by integrating schedule information for each. This provided the client and future projects a methodology for utilizing a data-based cost and schedule analysis for the selection of an alternative structural system. Additionally, Maine’s timber industry is in transition. With the decline of traditional pulp and paper milling in a state that is 90% forested, Maine's forest products industry has embraced the potential for growth and market expansion that sustainably-sourced mass timber products offer. With the creation of the Mass Timber Commercialization Center at the University of Maine and the endorsement of the Maine Forest Products Council for bringing this innovative use of timber in state, Maine and Bowdoin are ready to undertake a visible project utilizing mass timber materials. A mass timber building on Bowdoin College’s campus will showcase the potential of mass timber and encourage local industry growth.
