UofC McKimmie Tower Commercial Solar Installation Calgary (2022)
Project Overview
When people think of challenging solar installations, they often picture remote industrial sites or massive utility-scale projects. Few would expect one of Alberta’s most technically demanding solar projects to be located on top of a landmark university building in the heart of Calgary.
In July 2022, Zeno Renewables partnered with the University of Calgary and Stuart Olson to deliver a custom-engineered commercial solar installation Calgary atop the iconic McKimmie Tower. Rising high above the city skyline, the project required innovative engineering, meticulous planning, and flawless execution to overcome unique structural, logistical, and safety challenges.
The result is a 128 kW commercial solar installation Calgary capable of generating approximately 140,000 kWh of electricity annually while helping reduce operating costs and supporting the University of Calgary’s sustainability initiatives.

The Challenge: Building Solar on Calgary’s Skyline
Commercial solar installation Calgary always present unique considerations, but the McKimmie Tower introduced an entirely different level of complexity.
At over 20 stories above ground, every aspect of the project required careful coordination and engineering. Safety was paramount. Daily fall-protection planning, site-specific hazard assessments, and strict safety protocols were essential to protect crews working at significant heights.
The elevation also created substantial wind-loading concerns. While solar systems on conventional flat roofs are often designed using standard engineering approaches, the McKimmie Tower project demanded highly specialized structural analysis to ensure the system could withstand the increased wind forces experienced at higher altitudes.
Adding further complexity, the rooftop design required multiple custom mounting solutions rather than a single standardized racking system.
Custom Engineering from the Ground Up
One of the most unique aspects of the project was the rooftop layout itself.
Custom Elevated Array Structure
The central solar array could not simply be mounted directly to the roof membrane as is common in most commercial installations.
Instead, Zeno Renewables worked alongside engineers to design and install a custom-fabricated support structure capable of safely supporting the solar array while accommodating the building’s rooftop configuration.
Every component had to be carefully engineered to balance structural integrity, wind resistance, and long-term durability.
Curved Perimeter Solar Array
The perimeter section of the installation presented an even greater challenge.
The architectural design of the tower required solar modules to follow a curved rooftop profile. Traditional commercial racking systems were not suitable for this application.
To solve this, the team developed a fully custom-engineered racking solution specifically designed for the curved perimeter layout, ensuring proper module orientation, structural performance, and aesthetic integration with the building.
Unexpected Obstacles and Real-Time Problem Solving
Even with extensive planning, large commercial projects rarely proceed exactly as expected.
During installation, the perimeter racking system originally supplied for the project was discovered to be out of specification and incapable of supporting the solar modules as intended.
With project deadlines approaching, the team had to act quickly.
Zeno Renewables sourced an alternative manufacturer, coordinated approvals with the general contractor, completed new engineering reviews, and expedited fabrication – all while maintaining the overall project schedule.
The ability to rapidly adapt without compromising safety, quality, or timelines became one of the defining successes of the project.
Navigating Complex Electrical Requirements
Installing the solar equipment was only part of the challenge.
Connecting the system to the building’s electrical infrastructure required running large conductors through a lengthy elevator shaft while complying with all applicable electrical and building code requirements.
This work demanded close coordination between solar installers, electricians, engineers, and other trades working on the site.
The successful execution of this phase demonstrated the importance of communication, planning, and technical expertise when integrating renewable energy systems into large institutional facilities.
Results
Today, the McKimmie Tower solar array generates approximately 140,000 kWh of renewable electricity annually.

What Made This Project Successful?
Several factors distinguished this project from typical commercial solar installations:
Competitive Project Delivery
Winning the project required delivering a competitive solution without sacrificing engineering quality, safety, or long-term performance.
Execution Under Pressure
The team successfully maintained project milestones despite unforeseen equipment challenges and the complexities of working at significant heights.
Collaboration
Close coordination with Stuart Olson, engineers, electricians, suppliers, and other site trades ensured the project stayed on track from start to finish.
Lessons Learned
Every challenging project leaves valuable lessons behind.
One key takeaway from the McKimmie Tower installation was the importance of enhanced pre-construction quality assurance and quality control processes. Earlier identification of specification issues with the original perimeter racking system could have reduced project risk and accelerated execution.
Today, Zeno Renewables applies those lessons across all commercial projects through:
- More rigorous design reviews
- Enhanced QA/QC procedures
- Comprehensive stakeholder planning meetings
- Advanced project scoping and risk assessment
- AI-assisted review of large tender and RFP documents to identify critical requirements early
