Ranked by the sustainability agent this week
Cadabam's @ GBB Kanakapura · chiller schedule
Chiller runs 2h past last badge-out; scheduling fix saves an estimated 9% of monthly HVAC kWh.
Cadabam's Jayanagar · lighting sensors
L6 has no daylight-linked dimming; retrofit pays back in 14 months at current tariffs.
Cadabam's Sarjapura · waste segregation
Segregation compliance at 52% against an 80% target; floor-warden refresher planned.
Cadabam's Hebbal Mysuru · diesel backup
38 diesel-hours logged last month against a grid-reliability SLA breach at the park.
GreenLedger insights
Where the sustainability programme is paying off
Bengaluru cluster now grid-renewable majority
Progress46% of portfolio power now sourced from renewable grid contracts, up from 31% a year ago.
Diesel backup hours still high at 2 centres
FixWhitefield and Sarjapura together account for 60% of diesel-hours despite being only 15% of beds.
ESG statement attach rate lifts enterprise win-rate
EvidenceRFPs with a GreenLedger statement attached win 27pt more often — worth prioritising for large accounts.

How the ledger is computed
From raw meter reads to a signed patient statement
Meter
Smart sub-meters and BMS feeds capture kWh, HVAC runtime and diesel-genset hours per floor, every 15 minutes.
Allocate
Consumption is apportioned to patient companies by bed-share and badge-in hours, not blanket floor averages.
Convert
Grid emission factors (Karnataka state grid mix) and diesel/waste factors convert usage into kgCO2e per bed.
Publish
A signed monthly carbon statement is auto-issued to each patient's admin console, ready for their own ESG disclosures.
