Sustainable Measures in the STEM Learning Environment: AN APPROACH TO THE ENHANCEMENT OF S.T.E.M. LEARNING IN HIGHER EDUCATION
architects
ABSTRACT The acronym for Science, Technology, Engineering, and Mathematics, “S.T.E.M.,” has been a major buzzword within the U.S. for over the past decade and has taken on multiple connotations within the context of education reform. In 2012, the President’s Council of Advisors on Science and Technology (PCAST) projected an economic need for approximately 1 million more STEM professionals than the U.S. will produce at the current rate over the next decade in order for the U.S. to retain its historical preeminence in science and technology. Despite the large attention, research, and funding that has been invested in this issue, little progress has been made in increasing student retention in STEM fields. This research attempts to address the issue from a different angle by shifting more of the focus from the teaching methods and curricula to the sustainable built environment and the architectural design of facilities that best support these newly established practices. In order for cross-disciplinary, open and interactive learning associated with STEM to take place, it is necessary for an environment to be designed that best caters to these learning needs. It is with this idea that the built environment can also serve as a pedagogical tool to further engage students in the STEM learning process, especially in regards to addressing today’s critical environmental issues. This research analyzes the architecture of Sustainable STEM Learning Environments, providing a foundation for their progressive design using green technology and sustainable practices in support of STEM learning. This synergy of the architecture of STEM learning in conjunction with sustainable practices forms a symbiotic relationship between the built and natural environment that further enhances the student learning experience and improves performance, increasing student engagement and ultimately retention in STEM fields.

ISSUES/BACKGROUND 1. Waning Enrollment/Retention in STEM Fields Attrition Rate of STEM Majors About 28 percent of Bachelor’s degree students and 20 percent of Associate’s degree students entered a STEM field (i.e., chose a STEM major) at some point within 6 years of entering postsecondary education in 2003−04. 1
A total of 48 percent of Bachelor’s degree students and 69 percent of Associate’s degree students who entered STEM fields between 2003 and 2009 had left these fields by spring 2009.1

Economic projections point to a need for approximately 1 million more STEM professionals than the U.S. will produce at the current rate over the next decade if the country is to retain its historical preeminence in science and technology. 2 To meet this goal, the United States will need to increase the number of students who receive undergraduate STEM degrees by about 34% annually over current rates. 2 Figure 3:
Goal:
The graduation rate of STEM majors needs to increase to over 70% to fill this projected job gap.

2. Appropriation of Government Spending and Research in STEM Education In a report published by Henderson, Beach, and Finkelstein (2011), as illustrated in the chart below, most of the money, research, and attention allocated for STEM education has gone towards improving teaching methods and the design of new curricula; however, little focus has been placed on the architectural design of STEM learning environments to support this new approach to teaching. 3 It is with this knowledge that one can hypothesize an equivalent investment in sustainable architecture for STEM education will better combat the current national concerns associated with STEM. Focusing on changing the behavior without changing the environment in which this behavior takes place has come short of fully addressing the issue. The investment in new STEM curricula and teaching methods must be accommodated by an environment that supports this new form of education. We cannot expect large degrees of improvement by solely changing curricula and teaching methods if the built environment is not also changed in accordance with these new approaches to education. “Better models of the STEM ecosystem are needed to make investment decisions for the billions of dollars of investment in STEM.”4 Therefore, in order to better combat the STEM crisis, an equal investment needs to go towards designing, building, and testing environments that will best cater to the needs of STEM education.

3. Upkeep of Current STEM Learning Facilities in Conjunction with Emerging Educational Needs The traditional classroom environment is not reflective of new STEM teaching methods, which call for an interdisciplinary, engaged, “learn by doing/learn by sharing” approach in a unique, sustainable atmosphere. Just as STEM education promotes interrelationships and flexible, cross-disciplinary learning, so too should its built environment be flexible and constantly in flux to work with nature. A Sustainable STEM Learning Envrionment will consistently adapt and change according to exterior conditions in order to provide the best environment for learning. By doing so, STEM classrooms themselves can serve as a teacher and source of learning for students by explicitly illustrating in a real-life context how they function, how they adjust to their surrounding contexts, and how they work with a focus to natural elements. As a result, students can become engaged in these active learning environments and work with teachers, administrators, and the community in the research/planning/design process of these spaces. The classroom and laboratory environments should themselves serve as pedagogical tools, or as Anne Taylor, author of Linking Architecture and Education: Sustainable Design of Learning Environments, refers to them as, “3-D textbooks.” 5

4. Separation of STEM Departments within Institutions of Higher Learning The higher education system works along the basis of compartmentalizing areas of study into more and more specific majors so that students continue to specialize throughout their education into a very narrow scope of learning.6 Yet, we know that the big problems of today call on the resources of multiple people with various specialties, so why not start bringing these majors together to begin tackling these pressing issues? And while we’re at it, we can inject a series of sustainable measures to further enhance the learning environment. Creating an environment in which students from all fields of study are able to come together to work on projects addressing these “real-world,” pressing global issues will foster engagement and interest, particularly in STEM fields, in which waning enrollment and retention has been addressed as a national concern.
How can we encourage cross-disciplinary inquiry and engagement to promote collaboration across STEM majors with separate facilities? Example: Typical Categorization of University Depts. with STEM Degrees

5. Why Sustainable Design? “The commercial and residential building sector accounts for 39% of carbon dioxide (CO2) emissions in the United States per year, more than any other sector. U.S. buildings alone are responsible for more CO2 emissions annually than those of any other country except China.” 7 The built environment is the biggest contributor to climate change, as it involves a one-way transfer of energy from the natural environment. Not only should it be a priority to design buildings that significantly reduce their energy use, but in order to design truly sustainable spaces, they need to be connected to nature, rather than insulated from it, working with nature and not against nature. Sustainable STEM learning environments can offer a way to design, build, and test truly sustainable environments, in which the classroom is itself a testbed for new ideas, void of any restrictive boundaries.

Sustainable, Pedagogical Environments As the two previous case studies illustrate, the architecture of STEM learning environments has the opportunity to be both innately pedagogical and sustainable, in which the building itself serves as a teaching tool. Students are automatically able to be engaged in the learning process through the building’s revealing structure and illustrative mechanical systems that demonstrate how the building functions, as in the Institute for Sustainability at RIT. In addition, STEM learning environments, like the Loyola Science Center, highlight the importance of proper spatial organization and hierarchy of learning spaces to leverage the many forms in which learning occurs, from more private to public, student-student to faculty-student interactions. The building itself can serve as a testbed for learning and research and even leverage the creation and commercialization of what comes out of that research, as the next two case studies illustrate.

SOLUTIONS A Sustainable STEM Learning Environment Learning from and building upon the previous case studies and research compiled, we propose design guidelines for new STEM learning environments that both leverage and are leveraged by sustainable building practices, forming a symbiotic relationship between the built and natural environment that further enhances the student learning experience. With sustainable design no longer being just an option, but a necessity, the architecture of STEM learning environments has the opportunity to serve as a pedagogical tool, providing students with a real-world illustration of sustainable processes that work with and not against nature. This enhancement of the learning environment from being a passive setting to an active teaching tool allows the architecture to serve as a canvas for students to explore and test projects, manipulating their own built environment as a testbed for addressing the urgent environmental issues of today. It is with this approach that students will become more engaged and see the correlation between the curriculum and the real-world setting in which these learned principles are put on display and experimented with directly in the classroom. The following analysis at multiple scales, from macro-level building typologies down to micro-level sustainable material choices, attempts to provide a strategy for implementing the fusion and synergy of sustainable design with the architectural design of STEM learning environments. The goal is to then design and test a built environment based on these guidelines in the near future.

3. Hybrid - Sustainable STEM Addition Enhance or rehabilitate an academic building(s) by attaching a Sustainable STEM facility to the existing structure, creating a place for various disciplines to come together to work on real-world projects that require multiple expertise.
Example: Milstein Hall, Cornell University “The new Milstein Hall - a 14,000m2 complex...- is conceived not as a symbolic, isolated addition to the campus but as a connecting structure: a large elevated horizontal plate that links the second levels of Sibley and Rand Halls and cantilevers over University Avenue, reaching towards the Foundry building.” - OMA
Figure 53: Concept - Milstein Hall as “connecting structure”
“Milstein Hall provides a type of space currently absent from the campus: a wide-open expanse that stimulates the interaction of programs, and allows flexibility over time. Within Milstein Hall's upper plate, which has access to Rand and Sibley, areas are defined not by walls but by subtle manipulations of the section that trigger particular uses...” - OMA

Natural Materials The use of natural materials reduces the negative effects the built environment will have on the natural environment, while also increasing the efficiency and adaptability of the structure. “Natural materials are generally lower in embodied energy and toxicity than man-made materials. They require less processing and are less damaging to the environment. Many, like wood, are theoretically renewable. When low-embodied-energy natural materials are incorporated into building products, the products become more sustainable.� 10 Figure 67:

Smart Materials Smart materials are designed to posess one or more properties that can be significantly altered, without human control or added energy, by means of external stimuli, such as temperature, stress, pH, moisture, electric and/or magnetic fields. Replicate Homeostasis: Just as our bodies and other biological organisms react to the environment in order to maintain homeostasis, smart materials can act as a form of bio-mimicry, controlling energy use in a building by working with and reacting to their surrounding environments without the use of human or mechanical controls.
Example: Thermal Bimetal A lamination of two different metals together with two different coefficients of expansion, so that, when heated, one side expands faster than the other resulting in a curling action 11
Figure 74: The thermal bimetal designed by Doris Kim Sung serves as the building envelope, regulating building temperature much like the human skin does for our own bodies. It acts as both a sun-shading device and as a ventilating system, with each individual tile calibrated according to its specific location on the building, the angle of the sun, and the way in which it curls. 11.

STANDARD/IDEAL INDOOR ENVIRONMENTAL QUALITY (IEQ) CONDITIONS FOR LEARNING Temperature “Students will perform mental tasks best in rooms kept at moderate temperatures in the range of sixty-eight to seventy-four degrees Fahrenheit (Schneider, 2002, p. 2).” 12
CO2 Levels “There is still some disagreement as to whether 1500 or 1000 ppm is the safe maximum level (ventilation researchers prefer 1000 ppm, while practitioners often cite 1500 ppm). This current debate is reviewed more in depth in a paper by Wyon & Wargocki (2007).” 12
Ventilation “ASHRAE Standard 62 (now 62.1) still uses the rate established by research from 1936, of 10 cfm per person as its minimum acceptable outdoor air ventilation rate (ASHRAE, 2010b; Janssen, 1999).” 12
Lighting “The current ASHRAE Advanced Energy Design Guide, which is supported by IESNA (the former Illumination Engineering Society is now called Illumination Engineering Society of North America), advocates for anywhere between 30 and 70 footcandles for classroom spaces, while the IESNA guidelines for classrooms still use 50-100 footcandles as a guideline (Wu & Ng, 2003).” 12
Acoustics “[The] ANSI Standard 12.60 in 2002, a standard written by the Acoustical Society of America, which has since been adopted into the LEED standards for school buildings and a variety of other related performance standards for buildings (Acoustical Society of America (ASA), 2009; Kurtz et al., 2009)...calls for a maximum background noise level of 35 dBa in standard classrooms, with reverberation n times between 0.6 and 0.7 seconds, along with guidance and specifications for Sound Transmission Class ratings for exterior and interior wall assemblies, and Impact Insulation Class ratings to address floor-to-floor noise transmission.” 12 12.

“3-D Textbook” Sustainable Solutions What are 3-D Textbook Environments? The term, as coined in Anne Taylor’s book, Linking Architecture and Education: Sustainable Design of Learning Environments, is about an atmosphere for learning that is itself inherently pedagogical through its expression of concepts learned in the classroom. It takes the traditional two-dimensional learning that takes place and creates an experiential, three-dimensional space for learning through experimentation and collaborative or personal analysis, rather than having the material be spoon-fed. Sustainable Solutions as 3-D Textbooks The goal is to provide sustainable solutions that will also serve as teaching tools with the philosophy of the 3-D Textbook. These examples, when incorporated into a STEM academic building, should be showcased and highlighted, allowing students to witness each day the processes and principles they learn in the classroom on display in real life. This should also include the exposure of major structural components of the building as well as the intricate mechanics and plumbing that run throughout the building. Inherent in these components are the workings of STEM principles that can assist in the learning process and help bolster student engagement. It is important to note that the following sustainable solutions provided are meant to serve as examples that may be most appropriate for a STEM learning environment, but they are in no way limited to these examples.

Sustainable Solutions for the STEM Environment 1. Geothermal Energy Heating/Cooling through thermal energy stored in Earth Options: 1.
Application Type Closed Loop - In closed loop applications a high strength pipe made of thermal plastic is buried in the group and filled with a water and/or antifreeze solution that allows heat transfer to take place without the circulation of water. Open Loop - Open loop applications do not contain water and/or antifreeze solutions and instead utilize a nearby water source to circulate water, such as ponds or wells, in producing a heat transfer effect. 13
2.
Placement Horizontal Loop - Horizontal Loops need adequate land to accomodate loops laid horizontally below ground level, ranging from one-hundred feet to five-hundred feet in length Vertical Loop - Vertical loops are ideal when land surface is limited, as vertical holes about six-inches in diameter are drilled into the ground to depths ranging from one-hundred to three-hundred feet. This is the most common system used in neighborhood settings 13
3.
Pond Sourcing Loop Pond - A pond source heat pump is economical only when a body of water is nearby. In this application loop pipes are placed along the bottom of the body of water. 13

Figure 87: Illuminance analysis
Thermal Performance - R-Value R-value is a measure of thermal resistance in regards to conductive heat transfer across an insulator (the higher the R-value of a material, the more it is thermal resistant).15 Glazing with higher R-values optimizes building energy use without sacrificing natural light.

5. Natural Ventilation Passive Heating/Cooling Rather than relying on mechanical systems, heat is dissipated in order to achieve thermal comfort as a result of the architectural design of the building in conjunction with the use of on-site energy resources.15
Stack Ventilation (Stack Effect) Figure 89: Stack ventilation is a result of vertical air pressure differences due to thermal buoyancy. Dense, cool air is driven into the building and, as it warms, becomes less dense and rises up and out of openings in the building envelope.15 Outlet of warm air
Inlet of cool air
Computational Fluid Dynamics (CFD) Studies CFD studies allow a method for calculating fluid flows, measuring wind and air flow through and around the building as it sits within the site, in order to better inform decisions about building placement and massing strategies.

6. Green Roof Green roofs act like sponges, soaking up rainwater as it hits the roof, preventing erosion, runoff, and sewer overflows. They also help regulate the temperature of the roof, cooling through water evaporation, which ultimately keeps the building cooler, therefore using less energy during the warmer months.13 Figure 91: Green Roof Layers Soil/Planting Medium (Average Depth: 2.5 inches to 1 foot) Filter Mesh: Allows water to pass but keeps soil out - prevents soil loss through rain runoff (Average Depth: 1/4” to 3/4”) Perforated Water Retention Layer: stores water below soil for future use while openings drain excess runoff water into drainage layer (Average Depth: varies based on type) Drainage Layer: gravel to direct runoff towards roof drainage such as gutter, etc. Shown: optional pipe system for heavy flows (Average Depth: 1-5/8 inches including water retention layer) Root Barrier: prevents roots from growing into building structure and weakening it (Average Depth: 1/4” to 3/4”) Insulation (Average Depth: varies depending on soil thickness and intended R-value) Vapor Barrier/Waterproof Membrane: prevents structure from water damage by keeping out moisture and water (Average Depth: usually a thin sheet) Structure: roof supporting structure of building (concrete shown)
Figure 92: Section of Green Roof, highlighting water storage/drainage
Drainage Layer: Excess runoff is drained into gravel layer below via perforations in retention layer
Water Storage: some water is stored in retention layer for later use
Roof Drainage: gravel directs excess water into roof drainage (e.g. gutters)

CONCLUSION Summary of Findings STEM education has been targeted as a national concern for over the past decade, as studies have shown less and less students enrolling in STEM majors in higher education, along with falling numbers of students remaining in STEM fields and ultimately pursuing a STEM career. Although billions of dollars have already been spent addressing this issue, in order for the U.S. to maintain its prominent global presence as a leader in advancement and technology, the numbers have not seen much improvement. As other research has suggested, a reason for this could be the ways in which these resources have been allocated. Most funding and research has gone towards improving teaching methods and curricula, forming a new pedagogy best fit for the unique needs of STEM education, with much less focus on the built environment and facilities that house this education and its environmental impact. Building from this notion, the goal of this research is to provide an architectural framework and foundation for the design and construction of Sustainable STEM Learning Environments that will best cater to the new curricula and teaching methods that have already been researched and established. It is through this that we hope to focus an equal or greater attention on the built environment as on the curricula and teaching methods for STEM education, so as to better address the lack of improvement we have seen thus far in combating the STEM crisis in addition to the larger, global crisis of sustainability.

Implications for the Future By establishing a general basis of research in sustainable practices and methods in combination with architectural principles best suited for Sustainable STEM Learning Environments, the goal moving forward is to make use of this research by designing and testing a prototype for a possible Sustainable STEM learning environment (as seen on the following page). In the next phase of this research, the hypothesis asserts that when spaces that cater to the needs of STEM learning are designed in conjunction with sustainable practices and principles, a synergism results, in which the outcome of the design is greater than if either were to be taken into account separately. STEM learning environments can leverage sustainable design and vice versa, forming a symbiotic relationship between the built and natural environment that further enhances the student learning experience, which in turn increases student engagement and ultimately increases retention in these fields.
