HH Angus and Associates solves complex engineering problems, creatively. Solutions are successful and designed with the environment in mind.  
  • H.H. Angus was founded in 1919 and today is one of Canada's larger private engineering firms. 
  • Based in Ontario, Canada, and operating in Canada and the US. 
  • They partnered with Argentum to improve the comfort of their indoor office space for employees, optimizing for things like temperature, humidity, and air quality.

HH Angus had this to say about their project with Argentum: 

"We are installing sensors in selected conference rooms and volunteered workstations that will anonymously monitor occupancy and environmental conditions. We’re excited to be collaborating with Argentum Electronics, a Toronto-based start-up that is providing the sensors." - H.H. ANGUS AND ASSOCIATES

The space we were approached to help with was their office building space; approximately 25,000 sq/ft.

HH Angus explained to us that they were experiencing problems with: 

  • Temperature inconsistencies throughout the building
  • Verifying problem areas in each of their HVAC zones
  • Verifying air quality levels in general
  • Controlling lighting based on occupancy as opposed to with a set timer
  • Monitoring desk occupancy

Additionally, they wanted to be able to track and control all connected devices with a single cloud-based, user-friendly platform.

Ensuring that their office space is comfortable for their employees, and conductive to productivity, was a major focus for our partnership with them. their employees through the control of their workplace’s temperature and environmental quality was a large part of their request, but they also wanted a more energy efficient power system for LED lighting that they could automate and control based on data.


After analyzing the key problems and the space we determined that a combination of DC power distribution and POE, coupled with key products from our Spacr lineup was the ideal solution.

Our DC power distribution technology specifically was very beneficial in improving the energy efficiency of their space, as it eliminated energy wasted from having an AC to DC converter connected to each of their LED light fixtures. You can read more about the harmful effects of AC to DC conversions on our blog.

We also implemented IoT technology and digital twin software that allows HH Angus to track, measure, and control all connected devices in real time.

By implementing our wireless sensors, we were able to target specific areas of improvement: 

With SpacrSense occupancy sensors, we could track the availability of desks, boardrooms, and washrooms in real-time.

Our SpacrSense IEQ sensors, specifically, played a big part in targeting HH Angus's unique areas of improvement. Argentum's SpacrSense IEQ and IAQ sensors (Indoor Environmental Quality and Indoor Air Quality) monitor the major data points crucial for determining the indoor environmental quality in a building. Automations can then be based off the ideal conditions for a safe and comfortable workplace. Specifically, with these sensors, HH Angus can monitor and control things like temperature, CO2 levels, humidity, ambient light levels, light colour temperature and more.

We connected our SpacrApp to these sensors so that, simply put, all collected data could be monitored, tracked, and used as a guideline to make the HH Angus office building more energy efficient, and comfortable for employees.

Specifically, the SpacrApp allows our client to:

  • Automate lights to shut off if an area is vacant. This is an improvement to the timer-based system, which was the client's alternative.
  • Track and control all connected devices (such as lighting and HVAC) through a single, cloud-based platform. This allows them to target temperature inconsistencies throughout the building, for example.

By connecting the Argentum system to the client's lighting and HVAC system, IEQ and IAQ sensors could be used to identify temperature inconsistencies, and less than ideal lighting conditions. With the SpacrApp (the Argentum digital twin platform), the client now has the power to monitor and control their lighting and HVAC systems to optimize their building for comfort, safety and efficiency.

Target specific rooms with full, data-backed, control over HVAC (demand controlled ventilation) and lighting systems.

Wireless sensors collect data, and the client uses a customized, interactive digital twin of their building to monitor, control, automate and optimize their lighting and HVAC systems.

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?

We transitioned the client’s lighting automation system from being timer based, to occupancy-based.

This feature was enabled by Argentum's occupancy sensors.

Daylight Harvesting Enabled

Daylight harvesting provides energy savings of up to 24%.

Financial Results

50% Capital Expenditure Savings
  • 50% savings versus traditional PoE.
  • 50% savings versus traditional line voltage and controls.
  • No conduit/mechanical protection needed for low voltage cable runs.
30% Savings on Operational Costs
  • Roughly 30% reduction in energy consumption across lighting and HVAC.
  • LED light lifetime extended to 100,000 hours (inherent benefit of DC power distribution).

Ultimately, Argentum transformed HH Angus's approximately 25,000 sq/ft. traditional office building into an interactive intelligent space. We installed various sensors, Power over Ethernet (PoE) lighting, and Digital Twin software. Since implementing our solution, the client has experienced the ability to monitor and remedy any temperature discrepancies, leading to happier and more productive employees, as well as energy savings.

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

We've developed an electrical system to change that.
