Our Solution
4D Monitoring’s wireless light sensors provide real-time visibility into lux levels and utilisation trends across every monitored space. By highlighting areas that are over-lit, under-lit, or left illuminated outside occupancy, facilities teams can cut waste, improve tenant comfort, and ensure compliance with workplace lighting standards.
Data streams securely into our cloud platform, where automated alerts flag anomalies and long-term analysis supports energy optimisation, better scheduling, and evidence-led decisions.
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
Lighting accounts for up to 40% of a commercial building’s electricity use. Without visibility, systems are often left running unnecessarily or set to inappropriate levels.
<why it matters>
Wasting Energy
Lighting often accounts for a large share of a building’s electricity use. When lights are left on overnight, during weekends, or in areas that sit empty, energy is wasted and service charges rise unnecessarily. Without visibility, these patterns often go unnoticed for months.
Sustainability
For landlords and occupiers working towards net-zero targets, uncontrolled lighting waste makes it harder to hit reduction goals. Monitoring provides the hard data needed to cut energy use and demonstrate genuine progress on sustainability.
Case Study
At Swan Lane, a 60,000 ft² multi-floor office in central London, 4D Monitoring installed discreet sensors to track lighting usage across tenant spaces. The data revealed that lights were frequently left on outside normal operating hours, contributing to unnecessary energy consumption and higher service charges.
With clear visibility of when and where lighting was being used, facilities teams were able to adjust schedules and tenant engagement. This led to measurable energy savings while maintaining comfort and compliance with workplace lighting standards.
