About the Client

Cherishome is an international asset management company that strives to create thriving, safe communities.

  • 13 properties, and 2000+ suites in Canada
  • 9 communities and 2100+ suites in the United States
  • Owner of "The Citadel" building in Toronto, ON
  • Cence partnered with them to improve a problem they were having with The Citadel's dryers in their residential communal laundry room

The Cherishome Toronto team had this to say about their company: 

"We believe it is our obligation to have an appreciation for our own blessings in life, having the desire to be caring, making courteous service our great passion, and in doing so, being a thankful team of people living out our gratitude by truly caring for others." - Cherishome Toronto Team

The Challenge

The client was experiencing concrete damage in stairwells caused by the dryer exhaust system blowing acidic moisture into them. Because of this, Cherishome decided they needed to redirect exhaust from the underground laundry rooms to the main floor. When they partnered with us here at Cence they explained this, as well as that they needed to automatically control exhaust fan speeds based on the number of dryers being used at the same time.

The ability to control fan speeds was necessary because, without that ability:
  • The temperature of the exhaust could rise to dangerous levels, putting tenants and people in the building at risk
  • Fans could’ve damaged idle dryers due to over extraction of the exhaust
  • The energy used to operate fans connected to idle dryers would be wasted, unnecessarily increasing electricity costs

The Solution

Cence decided that the best method to automatically detect if dryers are being overused would be to use thermistors to measure the exhaust’s air temperature, and send that information to the smart node product, as well as the Cence App (includes digital twin software). These are two of the most common products that we implement for clients because of their powerful data collection and control software.

With these products, we were able to implement a wireless mesh network to control and automate the central exhaust system for all dryers:

The combination of these technologies, provides Cherishome with these benefits: 

  • The natural gas supply will automatically shut off in the case of an exhaust fan failure
  • Automating the exhaust fan so that its speed is increased or decreased based on usage of the dryers provides demand controlled ventilation (DCV), which saves energy and operating costs
  • A wireless mesh network spans from the laundry rooms to the natural gas supply location, saving Cherishome the cost of very long lengths of wire, and a very complicated installation process

By integrating these devices with air temperature sensors, a wireless mesh network, and our digital twin software, we enabled Cherishome to monitor, control and automate their dryers and exhaust fans based on real-time usage and safety protocols. This allows Cherishome to optimize energy consumption, as well as occupant safety.

Intuitive control with digital twin software

The cloud app is optimized for use with BACnet, and is also an intuitive app with a user friendly interface. The Cence App includes digital twin software that produces a digital floorplan or layout of a physical space or system. This way, the dryers and exhaust fans, can easily be controlled in real-time.

Energy savings

The automations implemented with the Cence system save Cherishome on energy, and operating costs.

Financial Results

50% Capital Expenditure Savings
  • Implementing the Cence wireless and programmable system with radio frequency (RF) links, eliminated the cost of wires that would've been necessary with the alternative.
60% Savings on Operational Costs
  • The Cence data collection software enabled us to understand that our solution saves Cherishome 10 - 15 kWh annually on energy consumption of motors.

All in all, since the implementation of our system, Cherishome has been able to save energy costs, reduce emissions, improve occupant safety, and improve the performance of their dryers.
