A selection committee from the President’s Sustainability Council identified projects that advance climate action at the University for the second round of funding from York’s Sustainability Innovation Fund (SIF). 

The Sustainability Innovation Fund provides funding to support campus sustainability projects that help build a culture and practice of sustainability at York University and advance the United Nations Sustainable Development Goals (SDGs). This round of funding awarded over $50,000 to projects that contribute to the University’s goal of reducing greenhouse gas (GHG) emissions by 45 per cent by 2030 and achieving net zero and advancing SDG 13 (Climate Action).  

The winning projects reflect various ways to utilize the campus as a living lab and address direct or indirect emissions through activities such as commuting, energy use, food consumption, waste management, behaviour change, awareness and engagement, and nature-based solutions.  

“By supporting these projects, we are making significant strides towards creating a more sustainable community at York University and beyond,” said Mike Layton, chief sustainability officer. “We’re also breaking down financial barriers to empower students, staff and faculty to become agents of positive change and take meaningful steps to reduce our impact on the planet.” 

The four winning projects are:  

Living Learning Community – Sustainability  

  • Project team: ​Aaron Brown and Melanie Howard​, Residence Life, Division of Students ​  
  • Residence Life will pilot a Living Learning Community (LLC) specific to sustainability during the 2023-24 academic year. The program seeks to address SDG 12 (Ensure sustainable production and consumption patterns) and 13 (Take urgent action to combat climate change and its impacts).

Microlecture Series in Sustainable Living: Building a better future with Usman Khan

Globe and York branded box for the Microlecture Series launch

York University’s free Microlecture Series in Sustainable Living is an innovative, interdisciplinary and open access program that gives participants the opportunity to earn a first-of-its-kind digital badge in sustainable living.

Throughout the Microlecture Series in Sustainable Living, six of York University’s world-renowned experts share research, thoughts and advice on a range of critical topics related to sustainability. Their leadership and expertise, however, extends beyond the six-minute presentations.

Over the next several weeks, YFile will present a six-part series featuring the professors’ work, their expert insights into York’s contributions to sustainability, and how accepting the responsibility of being a sustainable living ambassador can help right the future.

Usman Khan
Usman Khan

Part three features Associate Professor Usman Khan.

Usman Khan is an associate professor of civil engineering at the Lassonde School of Engineering. His research interests lie in water resources engineering, focusing on urban hydrology, including flood risk assessment and uncertainty analysis, sustainable water resource management and infrastructure, and the impacts of climate change on these systems. Khan specializes in developing novel machine learning and artificial intelligence methods for various engineering applications. The role of civil engineering in creating vibrant, liveable and sustainable cities is a strong motivator for Khan. He is committed to using his professional practice to meet the challenges that face the urban environment. 

Q: What does it mean to be a “sustainable living ambassador” and how does it foster positive change? 
A: Being a “sustainable living ambassador” means, first, that you’re committed to learning about global sustainability problems, such as the climate crises, and second, that you’re committed to creating positive change in your community – either through direct action or through advocacy. As more people become ambassadors, I hope the discussions about sustainability on campus increase and that these discussions then lead to positive change on our campuses. Sustainability is an integral component of our University’s mission (University Academic Plan) and therefore, I think the York community should be well-versed in the topic.

Q: What would make you most proud for viewers to take away from your lecture, and the series as a whole?
A: The role of engineers in designing and creating a more sustainable world is under-appreciated. I hope that viewers who watch my lecture understand how important a role engineering design can have on sustainability in our communities. The design of engineering infrastructure – even relatively simple technologies to manage stormwater – influences each component of sustainability: environmental, social and economical. I want viewers to learn that, indeed, there are more sustainable options for stormwater management, and deciding who receives this sustainability benefit is an important decision. We should be demanding more sustainable solutions.

Q: Equity and equality are a common theme throughout these sustainability lectures. Why is that such a critical component of sustainability? 
A: We need to make sure that any new technologies and systems that are designed and implemented are providing benefits to those who need them the most. In my work, this means providing engineering solutions, for example for flood risk reduction, to people who are most at risk and disadvantaged.

Q: Are there changes you’ve made in your work at York that other York community members can learn from? 
A: I am fortunate to be able to commute to campus via public transport – despite two subway stations and bus connections, I know it is not easy for everyone in the York community to be able to do this. Since the transport sector is responsible for 25 per cent of greenhouse gas emissions, it is important to me personally to commute using low emission modes.

I am not convinced yet that paperless assignments are a better route than traditional approaches. I am wary of the size of emissions from increased online education (online assignments, streaming lectures, life-cycle cost of all our new devices, etc.). Much of York’s online infrastructure is powered by data centres (off campus) which use a huge amount of energy to store all of our assignments and data in “the cloud,” and host all of our Zoom lectures. I would encourage community members to think about these “hidden” emissions when they are participating in academic life on campus.

Q: How do you view collective responsibility vs. personal responsibility in creating a more sustainable future?
A: This is a difficult question to answer, and I am not an expert in this area. I think that personal responsibility alone cannot be used to address the climate crises and sustainability more broadly. For example, substantially reducing our emissions requires a fundamental change in our systems, and small, personal actions are not the path to this change. Heavily focusing on these small, personal changes, takes attention and energy away from the systemic change needed for a more sustainable future. Our collective attention should be on large-scale, system-wide solutions that are urgently needed.

Q: How is York leading the way towards a more sustainable future? 
A: As a university, York’s strength in creating a more sustainable future lies in its role and responsibility in training the next generation of leaders and innovators. Having sustainability embedded in its academic curriculum, research enterprise, and in operations, means that thousands of students are exposed to new ideas and expertise in sustainability every year. These students, with this new knowledge, will be the foundation for the system-wide change that our planet needs.

Lassonde receives $250,000 bursary from Kenaidan Contracting

Lassonde School of Engineering contest

The Dr. Istvan Fogarasi Kenaidan Contracting Bursary will go towards supporting undergraduate students enrolled in the Civil Engineering program at York University’s Lassonde School of Engineering.

“There are two main reasons that we are providing this additional bursary to Lassonde students,” says Aidan Flatley, president and CEO of Kenaidan. “For one, it’s in memory of Dr. Istvan Fogarasi, who started the engineering department at Kenaidan and was a great mentor to our younger engineers. Second, to provide financial support to a Lassonde student that will allow them to concentrate on their studies instead of their monetary needs. The Lassonde School of Engineering has been a great source of co-op students and graduate engineering candidates for Team Kenaidan.”

Jane Goodyer

“It’s incredible to see this show of support from Kenaidan for our students,” says Jane Goodyer, dean of Lassonde. “Partnerships like this are so valuable for our School and help our students excel. We are so grateful to the Kenaidan team for their generous contribution and look forward to continuing working together to create positive change.”

The bursary is a top-up and amendment to a previous University award that Kenaidan had, making it exclusive to Lassonde students. Kenaidan has been a valued partner for Lassonde for some time. It’s supported Lassonde’s Civil Engineering Industry Night for the past eight years, and since 2016 has offered co-op opportunities to students, bringing on 10 since then.

“Throughout my time in the civil engineering program at Lassonde, I was exposed to innovative learning opportunities paired with a series of challenges that prepared me for a successful start to my career at Kenaidan,” says Julia Ferlisi, project engineer at Kenaidan and Lassonde alumna. “I’ve been able to apply the technical knowledge and soft skills I developed throughout the program on a day-to-day basis with various stakeholders, from subcontractors to owner and consultant levels. Kenaidan develops its employees, particularly new graduates, to adopt the positive company culture and presents them with opportunities that challenge them to grow professionally. Seeing Kenaidan give back to the institute that got me to where I am today reassures me that students at Lassonde will see the value in the contractor side of the industry and ignite a passion for this work in the early stages of their professional development.”

The bursary will be available to all Lassonde students in the Civil Engineering program starting Fall 2023. Recipients must be Canadian citizens, permanent residents or protected persons, residents of Ontario, and demonstrate financial need. Preference will be to provide 50 per cent of the awards in any year to a female-identifying student.

Professor’s work shines light on Northern Lights

Northern Lights

In March 2023, cities across Southern Ontario witnessed a rare occurrence of the Northern Lights. A source of wonder for many, for Afshin Rezaei-Zare, associate professor in the Electrical Engineering and Computer Science department at York University’s Lassonde School of Engineering, it was an example of the focus of his research on geomagnetic disturbances (GMD) and their impacts on society and technological infrastructures.

“The event that many people witnessed in the Greater Toronto Area was caused by a relatively weak geomagnetic solar storm,” says Rezaei-Zare. “Strong solar winds from the storm pushed the sun’s particles deeper in the atmosphere, ionizing more gases and moving them to lower latitudes than we usually expect; that is why we could see these lights in the GTA,” he says, explaining the event.

Afshin Rezaei-Zare
Afshin Rezaei-Zare

Solar winds are streams of materials from the sun, mainly charged particles like electrons and protons, that can come in contact with Earth’s magnetic field and collide with gases in the Earth’s atmosphere, emitting the flares of light that are commonly known as the Northern Lights. There is more to them, however, than a beautiful sight.

“When the Earth’s magnetic field is hit by coronal mass ejections and intense solar flares, similar to but stronger than what happened in March, they can cause geomagnetic disturbances in addition to expanded northern lights,” says Rezaei-Zare. “This can have a widespread impact on technology, even damaging things on the ground level.”

Rezaei-Zare’s work focuses on how those geomagnetic disturbances are potentially dangerous fluctuations in the Earth’s magnetic fields, causing geomagnetically induced current (GIC) to flow through ground-level power systems, transmission lines and transformers. His research aims to focus on taking preventative measures and understanding the effects of space weather and resulting geomagnetic disturbances to help develop protection for vulnerable ground-level technologies. Those technologies which can be overwhelmed with thermal stress, damaging their functionality and leading to harmful effects such as large-scale power outages, as occured in Quebec in 1989 when a strong geomagnetic storm left the entire province without power for more than nine hours.

Using calculations, modelling techniques and computational tools, Rezaei-Zare analyzes the impacts of geomagnetic disturbances on various power systems, identifying components that are vulnerable to malfunction or damage from geomagnetically induced current.

In recent and ongoing research, much of it first-of-its-kind scientific literature, Rezaei-Zare has investigated the impacts of geomagnetically induced current on various equipment and systems, including transformers, generators, protection systems, renewable resources and High-Voltage DC (HVDC) systems.

This research provides crucial knowledge to manufacturers and power utility companies, allowing them to identify and protect their vulnerable equipment to better prepare for the potential effects of solar storms, allowing for updates to technical guides and standards for power equipment.

Leading research teams with domestic and international members and collaborators, Rezaei-Zare continues to work towards understanding geomagnetic disturbances and their impacts on power systems, to protect Earth from the harmful effects of solar storms and space weather.

“The GMD research is becoming more and more important, but there are very few experts in the field because of how many disciplines are involved in understanding this single area of research,” says Rezai-Zare. “I want to use my combined expertise to stimulate knowledge and increase understanding of this unfamiliar field.”

Lassonde professor receives grant for 3D/4D printing in space

View of the Earth from space

George Zhu from York University’s Department of Mechanical Engineering received a $250,000 New Frontiers in Research Fund (NFRF) grant to conduct innovative research that explores metal manufacturing for space equipment using 3D and 4D printing in space to satisfy the actual demands of materials needed.

Zheng Hong (George) Zhu

Spacecrafts are frequently manufactured with extra materials and spare parts to prepare for potential mission challenges and vicious movements during launch, making them overdesigned for the calm, vacuum, zero-gravity environment in space. When the excess materials aren’t used, they contribute to unnecessary waste, financial burdens and launch and process-related carbon dioxide emissions on Earth.

“Less than five percent of spare parts carried on space missions are actually used,” says Zhu. “If equipment was manufactured where it is needed, we could make space exploration more sustainable.”

Zhu’s work will involve collaboration with fellow Lassonde School of Engineering mechanical engineering professors Alidad Amirfazli, Cuiying Jian and Aleksander Czekanski, as well as taking full advantage of the diverse fields of mechanical engineering research at York, including space instrumentation and robotics, molecular dynamics, metals and alloy materials and fluid mechanics.

“Space has different conditions than Earth that will affect 3D printing, mainly zero-gravity and vacuum, so there will be a lot of exploratory work,” says Zhu. “When we use 3D printing on Earth, the gravity helps create strong bonds, but we don’t know what will happen in conditions without gravity. It is possible that the vacuum might cause molten metals to vaporize and disappear right in front of us.

“We want this to work but at this stage, we don’t know what will happen. We are actually the first to do this kind of research with metals,” he adds.

Using equipment obtained with substantial funding from the Canadian Foundation for Innovation (CFI) in 2019, this project will simulate space-like conditions to determine the feasibility of, and potential practices for, metal 3D printing in space. 3D printing will be performed in a large vacuum chamber, while modelling zero-gravity by printing in a horizontal orientation rather than vertical – this helps avoid the direct pressure from gravity that supports the creation of strong bonds.

The newly funded research will also explore the use of 4D printing, a new method of 3D printing that incorporates the dimension of time and may be useful in the development of deployable spacecraft components, like solar panels. Using shape memory alloys (SMA), 4D printed materials can remember and revert to their original shape after being deformed by certain stimuli, presenting a potential application for spacecrafts that spend long periods of time in space and are vulnerable to damage from debris.

Contributing to sustainable spacefaring effort, this exploratory project will take the first steps towards using space as an on-demand manufacturing site for space equipment. This project will also explore new and exciting ideas that can change and improve the design of space equipment, including the recycling of materials from debris to repair and manufacture materials for space activites.

“We have plans and ideas for applications, but this research is very new,” says Zhu. “I’m excited to learn as we go and discover the unknown. If this is successful, it will change the future of space exploration.”

Lassonde-funded course highlights colonial impact on Indigenous people

Notes lecture workshop meeting

Indigeneity and Decolonization in a North American Context, an eight-session course supported by Lassonde EDI Seed Funding, concluded its exploration of themes, methods and concepts in Indigenous studies and knowledge in relation to ideas in sociology.

The course, which successfully concluded in March, was open to the Lassonde community – including students, staff and faculty members. It focused on the “truth about colonialism,” based on Indigenous history and ethnographies, to demonstrate the impact of white colonial history on all Indigenous people, within a North American context.

Indigenous feminism and storytelling were at the forefront of this course, along with discussions about the colonial structures that have facilitated limited access to resources for Indigenous people with regard to employment, education, housing and more.

A significant portion also outlined the perspective of a settler scholar, as part of a decolonial movement, to teach the disruption of colonial policies, procedures and institutional structures that work towards the eradication, marginalization and oppression of Indigenous people in Canada. 

This course was a result of the successful application by Jeffrey Harris, associate professor and director of Common Engineering, as well as Emma Posca, a PhD candidate, former Lassonde staff member and current teaching assistant in the Department of Electrical Engineering and Computer Science.

Posca led the course, drawing on her PhD work in the School of Gender, Feminist and Sexuality Studies, and her dissertation which uses theories, methods and concepts such as Indigenous feminism, allyship, intersectionality, critical race theory, ethnography, patriarchy, colonialism and decolonization.

The curriculum also included several guest speakers, including Alejandro Mayoral, executive director and founder at Indigenous Friends Association, and Jennifer Meness, Bawajigan Waabanong (Dreams Tomorrow’s Dawn) Migizi minwa Biné Dodemok from the Algonquins of Pikwakanagan First Nation and assistant professor of Indigenous studies at Toronto Metropolitan University.  

“I want to give a big thank you and shoutout to Emma Posca for organizing this course and sharing her knowledge with us,” says Harris. “I found that this learning opportunity was thought-provoking.”

Posca shared the spirit of gratitude. “The support shown to me by Harris has been unparalleled,” says Posca. “I also want to recognize Lassonde’s EDI Seed Funding that made this series possible. I am honoured and privileged to be a part of this initiative. All the participants joined class activities with enthusiasm and encouraged each other to learn, feel safe, share great ideas and get creative.” 

Indigeneity and Decolonization in a North American Context was one of six projects that received funding as part of the EDI Seed Funding Initiative introduced in 2022, to promote a culture of EDI at the School while helping to remove systemic barriers for faculty, students and staff in academia. “It is our responsibility to work towards Indigenization and decolonization of the macro (the academy) and the micro (the classroom) so that more Indigenous people can have places and spaces that are reflective and inclusive,” concluded Posca. “I will continue to work hard towards Indigenization and decolonization initiatives and encourage others to do the same through initiatives like this one.”
