Our Solution
4D Monitoring uses discreet footfall sensors to track how many people enter and move through key areas such as lobbies, corridors, and shared spaces. By combining footfall data with occupancy and environmental metrics, you can see exactly when and where spaces are being used — and where energy or resources are being wasted.
Data streams to secure dashboards in real time, allowing FM teams, landlords, and operators to adjust cleaning schedules, optimise HVAC and lighting, and make evidence-led decisions about space design or service provision.


Occupant complaints are a common consequence of poorly managed temperatures, ranging from discomfort in underheated or overheated areas to frustration with inconsistent conditions between floors or zones. Beyond reducing satisfaction, frequent complaints place added pressure on facilities teams and can negatively affect productivity and wellbeing — issues highlighted in CIBSE’s guidance on thermal comfort.
Occupant Complaints
Wasting Energy
Without data, decisions about space use rely on guesswork or anecdotal feedback. Footfall monitoring provides objective insight into how buildings are actually used, supporting everything from energy savings to smarter service delivery and long-term space planning.
<why it matters>
Empty Areas
HVAC and lighting often run at full power in lobbies, corridors, or retail units even when footfall is low. Monitoring highlights where adjustments can be made to cut unnecessary usage.
Poor Visibility
Without clear data, it’s difficult to know which entrances, floors, or shared areas are busiest — or which are under-used. This makes it harder to plan layouts, allocate resources, or justify changes.

Case Study
At Bermondsey Square, footfall sensors were installed in shared lobbies and corridors alongside environmental monitoring. The data revealed long periods of low usage where HVAC and lighting were still running at full load.
By aligning schedules with actual footfall, the facilities team reduced wasted energy and improved tenant satisfaction. Cleaning routines were also adjusted to focus on the busiest areas, creating a better balance of service and efficiency.
