ED Modular and EllisDon


ED Modular is revolutionizing building construction by creating individual blocks, that stack on top of each other like LEGO to create a full building.
  • ED Modular is Ellis Don's prefabrication and modular division, with a 300,000 sq/ft facility located in Hamilton, Ontario.
  • They make steel-ribbed offices and other building blocks that revolutionize that way buildings are constructed; making it easier for war torn countries, for example, to rebuild.
  • ED Modular is an innovative company, that was looking for an innovative electrical system to match their products, and the sustainability goals of their company.

ED Modular Vice President Xavier Toby said this about the new ED Modular plant in 2020:

"The [ED modular] plant will be the biggest modular building facility in Canada...It is really about bringing a new technology and a new building method to the industry" - Xavier Toby

A large part of ED Modular's innovation efforts include ensuring that the power systems for their buildings are able to reduce energy consumption for occupants, and installation costs for ED Modular. This is key to reducing the cost of producing modules, and reducing the cost of operating them in the field.

ED Modular partnered with us, here at Argentum, to provide a superior, more energy efficient, and less expensive electrical system for their relocatable prefabricated/modular residential suites.


At Argentum, we decided that implementing our full Digital Current™ system would be the best solution to fulfill EllisDon’s request for a more energy efficient and less expensive electrical system.

The technology and Argentum products we used to achieve ED Modular's results include:
No items found.

The combination of these technologies creates a centralized, intelligent automation system for all connected devices, such as lighting and HVAC.

Devices Connected to the Argentum System:
No items found.

By integrating these devices with indoor environmental quality (IEQ) sensors, occupancy sensors, and our digital twin software, we enabled ED Modular to monitor, control and automate electrical loads based on real-time sensor data. This allows ED Modular to optimize energy consumption, as well as occupant comfort.

Target specific rooms with full, data-backed, control over lighting and HVAC systems.

Data collected from occupancy sensors and indoor environmental quality (IEQ) sensors allows ED Modular to control lighting and HVAC based on room occupancy, temperature inconsistencies, air quality, lighting inline with circadian rhythms, natural daylight in a space and more.

Lifetime of LED light fixtures lasts about 4x longer; extended to 100,000 hours.

This is an inherent benefit of DC power distribution, and if you'd like to learn more about why, we've written an entire blog post on the topic: Was the 100,000 Hour LED Light Bulb False Advertising?

Financial Results

50% Capital Expenditure Savings
  • A standard Power over Ethernet (PoE) system would’ve been roughly 50% more expensive than our hybrid PoE solution.
  • Our system does not require conduit or mechanical protection for wires on low-voltage runs.
  • Unlike with traditional PoE, we were able to use normal LED lights, and no expensive ethernet switch is required.
30% Savings on Operational Costs
  • Roughly 30% reduction in energy consumption across lighting and HVAC.
  • LED light fixture lifetime extended to 100,000 hours (inherent benefit of DC power distribution), this reduces maintenance costs.
  • Savings from Daylight Harvesting (enabled by our IEQ sensors)
ED Modular and EllisDon
All in all, since the implementation of our system, ED Modular has been able to save energy costs, reduce emissions, improve occupant comfort, and decrease the frequency LED fixtures need to be replaced.

Commercial buildings waste an average of 30% of energy consumed every year.

We've developed an electrical system to change that.
