Commercial Buildings & Hospitals
A mix of 24/7 critical loads and general spaces, benchmarked against energy use intensity per square meter.
In commercial buildings and hospitals, the consumption pattern is shaped by two fundamentally different load types: critical loads that must run uninterrupted around the clock, such as operating rooms, ICUs and server rooms, and general spaces whose consumption should track occupancy hours. Chillers, HVAC and lighting carry the largest share of consumption, and the standard benchmark is energy use intensity (EUI) per square meter of floor area. In hospitals, safety and hygiene requirements impose real constraints on changing equipment operating hours.
Energy management challenges in buildings and hospitals
A stark difference in consumption pattern between 24/7 critical loads and general spaces with limited operating hours
Poor HVAC on/off scheduling relative to actual building occupancy hours
Chiller efficiency loss with age and improperly tuned return water temperature versus actual load
Hospital safety and hygiene requirements that constrain changes to equipment operating hours
Lack of sub-metering across building zones, making it hard to pinpoint loss centers
Comparing energy performance across a portfolio's buildings without a shared normalized indicator
Gita 50001 for buildings & hospitals
Smart HVAC scheduling
Setting HVAC on/off schedules based on actual occupancy hours of each building zone, with exceptions for 24/7 critical areas.
Building energy use intensity index
Automatically calculating and benchmarking EUI per square meter of floor area to compare performance across a portfolio and track the annual trend.
Chiller efficiency monitoring
Tracking chiller coefficient of performance against cooling load and ambient temperature to catch efficiency degradation before a major failure.
Critical-load sub-metering
Separately monitoring energy consumption of critical areas such as operating rooms, ICUs and server rooms apart from general spaces for more precise savings analysis.
Lighting and daylight-effect monitoring
Analyzing lighting consumption by zone and time of day to identify daylight- and occupancy-based control opportunities.

Reduction potential from proper HVAC scheduling
Without hardware investment, from schedule correction alone
At a hospital complex, sub-metering critical departments separately from administrative and general spaces revealed that the administrative wing's HVAC continued running at full capacity outside working hours; correcting its schedule, without affecting clinical areas, lowered the building's overall energy consumption.
