Efficiency Savings Quick Screen
What is this efficiency measure actually worth?
Enter the consumption the measure acts on, what you expect it to save and what it costs. The screen returns the annual saving, where that saving comes from, and whether it pays back before the equipment wears out. Nothing is stored and nothing is asked of you — no account, no email.
Annual saving

81 000 kWh of electricity saved · 45.0% of the electricity this measure acts on
Computed live from the values in the form. Those start as worked examples, not your figures — change them to see your own case.
The measure returns its cost after 3.2 years and is expected to keep working for 10.0 — so it pays for itself roughly 6.8 years before the end of its life.

The demand component is 12.2% of this saving. A calculation that multiplies kWh by the unit price alone would miss it entirely — and would make the measure look worse than it is.
Simple payback only. It does not discount, does not escalate energy prices, and does not account for savings fading as equipment ages — all three matter in a real contract, and all three are part of the engagement rather than this screen.
What this screen cannot tell you
This works out what a saving you already believe in would be worth. It does not establish that the saving is real. That takes a measured baseline, and a way to prove afterwards that the energy actually went away — which is what Energy & Carbon Performance does.
- Measured baseline from real consumption data
- Measure-level savings assessed, not assumed
- Measurement and verification plan
- Savings persistence over the contract
- Contract structure and risk allocation
- Financing and procurement route
What this calculation is
An annual saving built from the four things a measure changes: electricity, billed demand, fuel or heat, and maintenance cost. It uses your figures throughout — your consumption, your tariff, your quoted cost, and the reduction your supplier claims. This screen publishes no benchmark and assumes nothing about your building.
- It does not estimate how much a measure will save. You supply that, from a quote, a study or a manufacturer's figure — and the answer is only ever as good as it is.
- It is not a guaranteed saving. An ESCO guarantee rests on a measured baseline and a verification method, neither of which exists here.
- It does not replace measurement and verification. Proving a saving happened is a different exercise from estimating that it might.
- Simple payback only. No discounting, no energy-price escalation, no allowance for savings fading as equipment ages — all three change the answer over a contract term.
How the saving is built
The whole calculation, in one line — it is short on purpose, because a screening tool you cannot check is not much use:
annual saving = electricity saved × electricity price + peak demand reduction × 12 × demand charge + fuel or heat saved × fuel price − change in annual operating cost simple payback = capital cost / annual saving
That is the same measure-level arithmetic FlowOps uses inside its ESCO model, not a simplified version of it. What stays inside the engagement is everything that comes after: the measured baseline, the verification plan, savings persistence, price escalation, and how the value is shared between the parties under a contract.
Efficiency Quick Screen methodology v1.0
Screening a whole building, not one measure?
This screen looks at one measure at a time. A real programme has a portfolio of them, competing for the same capital and interacting with each other — lighting changes the cooling load, controls change what the retrofit is worth. FlowOps runs that as a full ESCO model with a measured baseline and an M&V plan.
