Green Goals in Higher Education
In May, Edna Lorenz, PE, CEM, LEED AP, took on the role of Director of the Office of Campus Sustainability at Wayne State University. Previously, she served as the Energy Director at Corewell Health (formerly Beaumont Health), where she led a comprehensive energy and carbon reduction program across 22 hospitals. Before Corewell Health, Lorenz was a senior associate at Environmental Systems Design (now Stantec) in Chicago, managing LEED certification projects, energy audits, and renewable energy analysis. Here, she discusses the role, priorities, and future of sustainability at the university with SBN Detroit. Q: What led you to your current position? A: I am a mechanical engineer by training, having graduated from the University of Michigan. My first job out of college was with an engineering firm where I focused on energy and sustainability consulting for commercial buildings, with a specialization in the LEED green building rating system. In 2016, I took a position as Energy Director for the Beaumont Health System, now Corewell Health. While at Corewell, I found it very rewarding working on the operational side of the built environment, specifically optimizing building performance to reduce the energy consumption and carbon footprint of the hospital system’s 22 campuses. However, I wanted to get back to my green roots. I transitioned to higher education and began my role at Wayne State in May. It’s been fulfilling to work with a larger community, both on campus and within Detroit, who are deeply committed to sustainability. The students in particular are enthusiastic and have high expectations, which is very energizing. Q: What are your top priorities in this new role? A: My primary focus is to operationalize sustainability across the campus. We have a strategic framework, and I want to ensure our approach is practical and achievable for those executing the work. Initially, we are benchmarking current processes to identify what is working well, what isn’t, and where gaps exist. I am also collaborating with the academic side to integrate sustainability into all aspects of university life. Energy reduction is a top priority, and we have a strategic goal to reduce carbon emissions from building operations by at least 50% by 2030. Currently, we’re evaluating our buildings to find opportunities for both operational optimization as well as infrastructure improvement. Additionally, we are enhancing our waste management program by benchmarking current practices and identifying areas for improvement. We’re also focused on landscape and hardscape management to improve stormwater management and increase site permeability. We’re adding more trees and removing or replacing concrete with permeable pavers to achieve this and to enhance the campus’s appeal as a park-like community resource. Q: What strategies is the university implementing to reduce its carbon footprint? A: One great example is our student-run compost program. Our ‘Compost Warriors’ collect pre-consumer food waste — food scraps from food prep on campus — and transport it to the Georgia Street Collective, where it’s processed into nutrient-rich compost. Our grounds crew then uses it to fertilize the landscaping on campus. It’s a closed-loop process that reduces our carbon footprint while supporting a local organization. However, much of our scope 1 and 2 carbon emissions come from energy consumed by our buildings on campus. An example of how we are trying to reduce these emissions includes the installation and enhancement of automated controls for our buildings’ HVAC and electrical systems. By having the most up-to-date automation we can optimize how our buildings operate, from adjusting temperature controls based on outside conditions to turning off equipment when it is not needed. Q: What about recycling on campus? A: We are still working on benchmarking this area and have found it challenging to obtain accurate data due to the size of campus operations. Therefore, one of our first initiatives is to enlist students to help map waste stations around campus so we can chart the flow of waste leaving campus. We are also assessing the different types of waste streams, from hazardous waste from labs to construction waste from building renovations and used sports gear from the athletic department. Our aim is to identify all waste streams and find ways to divert as much as possible from landfills. Finally, we’re also looking at expanding the compost program at the Towers Café, a residential dining hall, with a pilot program this fall to divert post-consumer food waste as well as educate students on reducing overconsumption. Q: How are you addressing stormwater runoff management? A: Stormwater management is a significant issue in Midtown, where urban flooding has occurred. It’s a priority for us and our neighbors to explore ways to reduce runoff and prevent future flooding events. One of our major initiatives is to reduce hardscape and install more bioswales on campus as well as plant more trees and native vegetation. This will help reduce runoff and absorb more water onsite. A couple of examples of the progress we have made include installing permeable pavers on Anthony Wayne Drive in front of the residence hall as well as annual tree planting volunteer events with the Green Warrior student organization and our grounds crew. Q: What are the sustainable practices unique to the urban built environment? A: Being in an urban environment has its advantages. We have access to public transportation, and students and faculty can easily walk or bike to local amenities, which reduces fossil fuel emissions and the immense energy and materials needed to build private vehicles. However, challenges like air quality and urban heat islands also exist, but our campus has over 2,000 trees to help combat these issues, and we’ve been recognized as a Tree Campus by the Arbor Day Foundation, which we are very proud of. Our goal is to serve as a model for urban sustainability for other organizations and institutions of higher education. Q: How are students, faculty, and staff involved in sustainability efforts at Wayne State? A: Students are heavily involved. In addition to the Green Warriors and compost program, we work with our academic partners to identify
