A University of British Columbia engineer has developed a system that uses Wi-Fi signals to determine the number of people in a building and adjust the ventilation accordingly. By anonymously counting how many wireless devices are connected to Wi-Fi in a room, Stefan Storey's software tells UBC's building control system, which adjusts the ventilation in real-time. UBC's managing director says the system could help reduce greenhouse gas emissions by hundreds of tonnes, and save five per cent in energy costs per year for core campus buildings. It is to install the system in 10 more buildings in coming months.

By anonymously counting how many wireless devices are connected to Wi-Fi in a room, Stefan Storey's software tells UBC's building control system, which adjusts the ventilation in real-time. UBC's managing director says the system could help reduce greenhouse gas emissions by hundreds of tonnes, and save as much as $100,000 in energy costs per year for core campus buildings. It is to install the system in 10 more buildings in coming months.
