RYSE and the Annex Hotel

About the Client

Cence Power's partner on this project, RYSE, converts the typical shades in a home or building into smart shades, enabling their clients to conveniently control their shades with their voice, save energy by automating shades to lower on hot days, and more. Cence and RYSE teamed up to provide a solution for the Annex Hotel, a trendy hotel in the heart of Toronto, Ontario.

  • RYSE is an innovative company that's proud of their new evolution of motorized roller shades: RYSE SmartShades was launched in 2021
  • The Annex Hotel was founded in 2018, with a mission to provide an authentic city experience to guests, and make them feel at home while visiting Toronto
  • RYSE has worked with the Cence team on other projects as well
"[The Annex Hotel has] taken a so-called 'high-tech, low-touch' approach to hotel management to the extent where they are able to efficiently run their hotel with an average of just 1.5 staff for 24 rooms." - Operto

The Challenge

The Annex Hotel wanted to quickly motorize and automate their existing roller shades based on room temperature in order to improve the energy efficiency of their building's HVAC system. Specifically, they wanted to motorize and automate their roller shades to reduce the effects of "solar heat gain". Solar heat gain occurs when the heat from the sun emanates through windows or doorways, making a room warmer. This can make HVAC systems work harder to keep rooms cool in the summer months. In colder months, solar heat gain can actually be beneficial to HVAC systems because, if shades are open, heat from the sun can help HVAC systems to heat up a space. Whether in the warmer or colder months, this is where the automated, motorized roller shades of RYSE, and Cence Power's temperature sensors come in. We'll explain further how these technologies work to improve the efficiency of HVAC systems at the Annex Hotel in the next section.

Additionally, in order to create the automations, monitor sensor data, and view actionable insights generated from the data, the Annex Hotel needed a comprehensive cloud app that could communicate with their BACnet systems (such as their HVAC).

The Solution

In collaboration with RYSE, the team at Cence first decided to support the automation of RYSE's motorized roller shades with sensors. For this project, Cence implemented thermistors (temperature sensors), as well as indoor environmental quality (IEQ) sensors. IEQ sensors monitor for all the parameters that impact the quality of a building's indoor environment, and how these factors impact the occupants of a space. The sensors that Cence implemented are wireless, and involve a simple peel-and-stick installation. In order to collect data, the sensors are wirelessly connected to the Cence smart nodes, which create a wireless mesh network that is BACnet compatible. This wireless mesh network is able to communicate with BACnet systems because of the Cence BAS, which is integrated into the Cence App.

Cence Power's Digital Twin software and interactive cloud app, the Cence App, is also connected to the wireless mesh network (created by the smart nodes). This app collects sensor data, visualizes trends in the data, and generates actionable insights based on sensor data. An example of an actionable insight could be: "The east side of your building is generally warmer before 11am, would you like to automate your roller shades to open after 11am?"

The combination of these wireless sensors, smart nodes, and the Cence App, enables the motorized roller shades to support the Annex Hotel's HVAC systems, and make it more efficient.

It was essential that Cence Power's products not only connect to each other, and RYSE's motorized roller shades, but also to the Annex Hotel's native HVAC system and thermostats. This is where the Cence BAS (Building Automation System) came in. This BAS can be thought of as a language bridge that connects BACnet systems (such as the Annex Hotel's HVAC) to non-BACnet devices (such as RYSE's motorized roller shades).

By integrating these devices with Cence and RYSE technology, we enabled the client (the Annex Hotel) to monitor, control and automate their HVAC systems based on real-time IEQ sensor data. Ultimately, this allows the Annex Hotel to optimize energy consumption, as well as improve the comfort of their guests.

The Results

Blue checkmark with a circle around it

Motorized roller shades are automated based on room temperature and time of day to save energy.

Data collected from indoor environmental quality (IEQ) sensors allow the Annex Hotel to control their motorized roller shades based on room temperatures and time of day. This reduces the negative effects of solar heat gain. Research indicates that as much as 50% of the heat your home generates is lost through windows, so automated, motorized roller shades can make a big difference.

Motorized roller shades are automated for optimal comfort for guests to the Annex Hotel.

Data collected from indoor environmental quality (IEQ) sensors allow the Annex Hotel to control their motorized roller shades based on room temperatures and time of day. Not only does this reduce the negative effects of solar heat gain, but also helps to ensure the comfort of guests.

BACnet connection to roller shades and HVAC.

By enabling the technology of Cence and RYSE to communicate with BACnet through the Cence BAS, the Annex Hotel's HVAC system can be monitored and controlled via a cloud app.

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, lighting and HVAC in the Annex Hotel can easily be controlled in real-time.

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 a wired solution.
  • Enabling a cloud BACnet connection (as opposed to a traditional BACnet connection) additionally saves on wiring.
25% Savings on Operational Costs
  • This project was recently deployed, but is projected to save about 25% of the energy consumed by the Annex Hotel's HVAC system. This projection is based on typical energy savings gleaned from automating motorized roller shades to reduce solar heat gain.

All in all, we implemented a solution that:

  • Reduces solar heat gain
  • Was more cost effective to install than the alternative (a wired solution)
  • Did not require the Annex Hotel to purchase or install new shades, RYSE was able to automate and motorize the Annex Hotel's existing shades
  • Shades and the HVAC system are now able to be monitored, controlled and automated via a cloud-based app (with integrated digital twin software) from anywhere with a connection to the internet

It's projected that the Annex Hotel, will save 25% of energy consumed by their HVAC system going forward due to the implementation of this system. Additionally, this system will help to ensure the comfort of their guests.
