<\/p>\nThe traditional energy-per-square-meter metric no longer reflects how buildings are used\u2014especially in a world of hybrid working. With people counting technology, energy per person is emerging as the smarter metric, enabling real-time HVAC control and dynamic space management. This article explores how policy and practice must evolve to match.<\/p>\n
The traditional metric for evaluating building energy use\u2014kilowatt-hours per square meter\u2014no longer makes sense in an age of high-efficiency systems and fluctuating occupancy.<\/p>\n
<\/p>\n
It assumes uniform, continuous use of space, when in reality, buildings today are far more dynamic. A modern building may be equipped with state-of-the-art systems, but if it runs HVAC at full load while largely empty, it’s still an energy waster.<\/p>\n
Measuring energy-per-person<\/b> aligns building performance with actual human activity. It allows energy usage to be tied directly to occupancy, creating new opportunities for energy savings that go far beyond the limits of space-based metrics.<\/p>\n

<\/p>\n
This approach opens up smarter, occupancy-based controls that automatically reduce consumption in underutilized areas.<\/p>\n
People counting technologies have traditionally been deployed to optimize room bookings, space planning, and cleaning schedules. Now, the conversation is evolving: these systems are becoming key enablers of real-time energy efficiency<\/b>.<\/p>\n
Integrated with Building Management Systems via standard protocols like BACnet<\/b>, people counting data can guide dynamic adjustments to HVAC, lighting, and ventilation systems\u2014automatically aligning energy use with real-time demand.<\/p>\n\nHybrid Working & Dynamic Space Management<\/h2>\n
The rise of hybrid working<\/b> has added new complexity to building operations. Occupancy is now unpredictable: large spaces such as meeting rooms, communal areas, and restrooms may remain mostly unused for much of the day. Despite this, they are often still heated\/cooled, ventilated, and lit as if at full capacity.<\/p>\n
This is where people counting plays a transformative role. By continuously monitoring occupancy, systems can make smart decisions\u2014closing off underused zones<\/b>, consolidating usage, and adjusting environmental controls accordingly. Dynamic space management ensures that energy is only consumed where and when it\u2019s truly needed, while also improving user experience and operational efficiency.<\/p>\n\nPolicy Will Follow Technology<\/h2>\n
As policymakers look for more accurate and equitable ways to measure and regulate energy use, energy-per-person<\/b> is the natural next step. Reporting based on square meters doesn’t capture building usage patterns or occupancy trends\u2014especially under flexible work arrangements.<\/p>\n
Future standards must include occupancy-aware metrics to truly support sustainability targets and net-zero strategies. It’s not just about how efficient the systems are\u2014it’s about how intelligently they\u2019re used<\/b>.<\/p>\n\nThe Road Ahead<\/h2>\n
Occupancy-based control is not a futuristic idea\u2014it\u2019s available today, scalable, and already proving its value. Forward-thinking building operators are turning to people-aware automation<\/b> to meet both environmental goals and financial targets.<\/p>\nEmpowering Smarter Buildings with Terabee<\/h2>\n
Rethinking how we measure and manage energy in buildings is no longer optional\u2014it\u2019s essential. By adopting energy-per-person metrics, we can design environments that adapt to us in real time, cutting waste and improving comfort.<\/p>\n
