Smart HVAC

Overview
Project Overview
AltairX Technology is a company that delivers range of complex ICT solutions. For some of them they are using Shelly devices to develop complex and advanced solutions.
For a client managing over 50 buildings nationwide, they developed a SMART HVAC (Heating, Ventilation, and Air Conditioning) solution using Shelly devices, combined with environmental sensors.
Location / Scope
Italy - 50 company managed buildings across the country.
Goal
Intelligently controlling HVAC operations based on CO2, temperature, humidity, and light levels, enhancing
efficiency, saving costs, and reducing manual intervention.
Challenges
Find the right balance for energy-saving settings while keeping the comfort
Frequent manual temperature adjustments
Adapting adequately the comfort in changing climates
Solutions / Implementations
Solution
The developed solution uses the Shelly Plus 1PM Mini combined with environmental sensors for CO2, temperature, humidity, and light levels.
By monitoring CO2 and LUX levels, the solution can determine room occupancy. Every five minutes, it checks these data points, and if the room is occupied, it evaluates the temperature to decide whether to turn the HVAC system on or off. The Shelly Plus 1PM Mini manages the fan coil operation, ensuring efficient climate
control.
Products Used
Shelly Plus 1PM Mini
Shelly BLU H&T
Shelly API
Results
This approach has reduced HVAC usage by 40% per week in each room and improved user comfort, addressing complaints about the old, unintuitive thermostats.
Conclusion
Smart HVAC control systems offer significant advancements in energy efficiency, comfort, and convenience. By integrating sensors, IoT connectivity, and machine learning, these systems provide precise temperature management and adapt to user preferences and real-time conditions, ensuring optimal indoor climates while reducing energy costs. They allow for remote control, automated adjustments based on occupancy, and compatibility with other smart home devices, enhancing both user experience and environmental sustainability. As technology continues to evolve, smart HVAC solutions represent an essential step toward smarter, greener, and more comfortable living and working spaces.
