Summary

This project focuses on a client who owns a large 48-storey building with 96 air handling units (AHUs). The client has requested a proof of concept (POC) for air side optimization, which will include 19 floors and a total of 38 AHUs.

The primary evaluation matrix for this project will be based on the improvement in Energy Efficiency Rating (EER). The POC has last for 5 weeks, with one week dedicated to base line data collection and four weeks for the optimization period. The data for the project was collected using MQTT technology. The POC has been taken place during March and April of 2023.
