Expert in digital energy performance systems
Context
CYRISEA specialises in the development and integration of digital systems for the energy and environmental performance of buildings. They collaborated on a pilot project with the French nonprofit organisation Monde en Marge Monde en Marche ( MEMMEM) that provides quality housing to people in need.
CYRISEA participated as an integrator to accurately monitor the energy consumption of each housing unit. The project consisted of deploying efficient electricity and DHW (Domestic House Water) metering plans for the teams and ambient temperature sensors to ensure a fair distribution of rental charges and prevent any energy drift.
This project faced the challenge of implementing a reliable and sustainable system within the budget constraints of MEMMEM as it is a nonprofit and had to consider the lower incomes of the occupants of the housing units.
For CRYSEA to deploy its services, it needed an affordable connectivity solution that facilitated the use of temperature sensors and ensured the remote reading of electrical meters. Wattsense was the selected solution.
Solution
Energy drift results in overconsumption, and it occurs when buildings do not perform as well over time as they did when they were first constructed. Some causes of energy drift are equipment malfunction, staff changeover, changes made to set points, and building controls. Like everything, buildings must be well maintained and updated to keep them working optimally.
“The sensors and meters deployed allow us to follow the daily energy consumption of each housing unit, to correlate them with the temperature data of the living rooms, and to maintain the lowest possible consumption.”Quentin Yayon-Saintagne, Commercial Engineer at CYRISEA
CYRISEA proposed the equipment and architecture best suited to the project's physical and financial constraints: a radio architecture for the temperature sensors and meters directed to the Wattsense Tower to collect the data and transmit it on a free access Cloud for MEMMEM.
The Wattsense Tower is an interoperable cloud-based device that controls and monitors building equipment.
The CYRISEA team programmed the Wattsense Box, and their electrical partner did the on-site installation. The installation of the whole project took approximately two hours, and the company connected about ten radio temperature sensors and about 20 sub-meters (electricity and DHW) to the Tower.
Results
CYRISEA achieved its goal of ensuring energy efficiency and a fair distribution of rental charges for the low-income communities of MEMMEM's housing units.
The interoperability and simplicity of the Wattsense solution were the main advantages for CYRISEA to deploy reliable and sustainable equipment, allowing for the daily monitoring of energy consumption and preventing any energy drift.
“The simplicity of the Wattsense solution has allowed us to intervene quickly in private areas and, therefore, to avoid inconvenience to the residents. In addition, the subscription cost makes it possible for us to respect the customer's budget.”Quentin Yayon-Saintagne, Commercial Engineer at CYRISEA
