Commercial office buildings in Mumbai typically lose the largest share of avoidable energy to HVAC scheduling mismatched with occupancy and un-zoned lighting circuits, and BEE-backed studies show a savings potential of up to 40% in exactly these end-uses (Bureau of Energy Efficiency). At an office building in Mumbai, Maharashtra, Elion’s energy audit measured HVAC run-hours against actual floor occupancy and lighting zone control against usage patterns, finding both running on fixed, conservative schedules that didn’t reflect the building’s real occupancy profile. For a Grade-A or Grade-B commercial building in Mumbai spending upward of ₹1-2 crore annually on electricity, even a 15% reduction from scheduling and lighting-control fixes alone can mean ₹15-30 lakh in yearly savings without capital equipment spend.
This case study reflects a common pattern across Mumbai’s commercial office stock: buildings designed years ago for a specific occupancy assumption rarely have their HVAC and lighting controls revisited as tenancy patterns change. An energy audit closes that gap by measuring what’s actually happening against what the building management system assumes is happening, distinguishing between fixes a facility team can implement immediately and ones requiring landlord or tenant coordination. This case study covers the specific findings, the recommended corrective sequence, and the audit methodology used.
HVAC scheduling mismatched to real occupancy and un-zoned lighting are the most common energy-waste sources in Mumbai office buildings. This audit found both, projecting 15%+ savings on a ₹1-2 crore annual electricity spend through scheduling and control fixes alone.
