IoT for improving energy performance

Whether we’re talking about the residential or non-residential sector, the IoT makes it possible to optimize the energy performance of new and existing buildings in a high-emissions sector. Smart home and smart building solutions reduce costs, increase comfort, and benefit the environment...

Non-residential IoT

From offices, schools, and hospitals to hotels and shops, 1 in 4 buildings are non-residential buildings. The figures are clear: One-third of energy consumption and one-third of greenhouse gas emissions come from this sector. At a time when France is aiming for carbon neutrality by 2050 and enacting an increasing number of decrees and laws (Non-Residential Decree, BACS, etc.), reducing the non-residential sector’s energy bill is no longer merely an option. IoT is a valuable ally for improving building performance and meeting environmental, economic, and regulatory priorities.

Mandatory automation solution for all non-residential buildings beginning in 2025.

Having a BMS can lower energy use by up to 30%.

As a key player in Building Management Systems, the IoT assists facility managers with identifying ways to cut costs. The continuously transmitted data allows for real-time monitoring of various indicators such as temperature, pressure, humidity, ventilation, and electricity, as well as making necessary corrections while performing predictive maintenance.

  • A presence sensor allows smart lighting to be automated,
  • a temperature sensor allows the temperature to be adjusted based on the weather,
  • an optical sensor placed on an electricity meter detect deviations,
  • an energy consumption sensor monitors usage in real time.

Multiple scenarios—ranging from the most basic to the most complex—can be automated to meet legal requirements, reduce costs, and improve occupant comfort.

Overkiz is currently finalizing an entirely new solution for supporting professionals, especially those in the small- and medium-sized non-residential sectors with limited BMS solutions available to suit their needs. To be continued…

Residential IoT

With synergies between sensors, equipment, and smart devices and with protocols supporting an increasing number of brands, home IoT also offers a complete ecosystem to reduce energy consumption and improve residential heat distribution. Control tools, such as mobile applications, allow users to control their devices individually or in groups, and they can even program life scenarios based on schedules, occupant habits, the weather, and other factors. These home automation systems are essential for the residential energy management.

Heating: 40% of home energy costs

Air conditioning: 10% of worldwide electricity consumption

Highest cost: heating. Another bombshell: air conditioning. Multiple scenarios can be launched over the course of the day and the seasons:

In winter, when someone leaves for work, all the lights turn off, the shutters come down to retain the heat, and the heating drops to 16° and rises to 19° only a few minutes before the occupants return home. 

In summer, smart management of natural ventilation based on the number of hours of sunlight can limit the use of air conditioning, a real time bomb. When the sun rises in the morning, the smart roller shutters close to keep the indoors cool. In the evening, they open at the same time as the windows to circulate the air inside.

The environmental objectives for housing set by the Law on Energy and Climate and the RE2020 focus on decarbonization and putting an end to thermal sieves. With the IoT, players in the housing market, such as developers, manufacturers, and service providers, can now develop smart products and services for new homes and for the 20 million homes to be renovated by 2050. A huge market and a daunting challenge.

Overkiz is at their side in this race against time, as we endure global warming with an already recorded 1.5° degree increase in temperature.
