Yesterday’s Waste is Tomorrow’s Win
At Global Sustainability, we believe savings don’t just come from smarter future planning – they also come from correcting the past. That’s where retrospective cost recovery and optimization come in.
We dig deep into your historical utility bills, telecom contracts, vendor agreements, and infrastructure spend to uncover:
· Overcharges
· Billing errors
· Usage mismatches
· Missed rebates and incentives
· Outdated rate plans
· SLA violations or unused services
And we turn that information into actionable recoveries – real money back in your pocket, plus insights that help prevent future waste.

Real Value from Past Spend
Think of it like a financial time machine:
You have already spent money—now we investigate where it leaked, where it was wasted and how to recover it.
Examples of what we’ve found:
· Clients paying 20-30% more than market rate due to old utility contracts
· Missed sustainability credits from LED upgrades never filed for rebate
· Billed for telecom lines no longer in use
Service interruptions that triggered SLA credits – never claimed
The Power of Real-life, Real-Time Data
One of the most transformative elements in cost recovery is the use of IoT (Internet of Things) monitoring systems. These smart devices track how you’re building uses energy – down to the circuit, unit, or hour.
When we connect this data to your historical spend, the results are game-changing:
· Know what’s being wasted: IoT devices detect systems left running after hours, temperature mismanagement, and underperforming equipment.
· Identify the gap between usage and billing: See exactly where vendors overcharged for services you didn’t fully use.
· Quantify the return on your upgrades: Measure whether your LED, HVAC, or smart systems retrofits delivered savings – or just looked
· Inform new habits with real insight: Spot trends in occupancy, peak usage, and inefficiencies to change operations moving forward.
Bottom Line?
When real-life data meets strategic analysis, you gain control – and substantial savings.
Real data. Real results. Real refunds.
