The objective

Heathrow Airport has a reputation of being a sustainability leader. In 2019 Heathrow was named ‘Business of the Year’ by Edie’s Sustainability Leaders Awards (2019) due to its enormous effort towards climate change reduction. Heathrow has deployed a number of exciting initiatives such as: coffee cup recycling onsite, green corridors & recycled plastic-waste roads, and many more. They also have an ambitious carbon reduction target for 2020, whereby they installed 100,000 LEDs and a rooftop solar system which allows them to achieve 14% carbon reductions from their buildings year- on-year (Edie news, 2018).

LightFi and Heathrow are currently piloting another exciting initiative: an air handling unit (AHU) that responds dynamically to the number of people in real-time. This pilot is taking place at Terminal 4, covering an area of approximately 5,000 sqm. In order to for the AHU unit to respond to the presence of people Heathrow required data showing the real-time occupancy levels in and around the vicinity of the departure gates, in a completely anonymous and GDPR compliant way. The challenge is that the area has a very dynamic occupancy pattern, with around 300 passengers passing through each gate, with an average waiting time of 30 minutes.
