Design a data estate against carbon, energy, water and waste, from sourcing through to disposal.
Thirteen modules following the data lifecycle: source, model, store, process, place, serve, index, retain, dispose and telemetry, each measured against SCI, and each ending in the design gate that stage cannot be signed off without.

How the course works
One lifecycle, one expression
SCI runs through all thirteen modules, with E split into stored, moved and scanned, I as the carbon-aware term, M as media and servers, and R as the functional unit you choose.
A design gate at every stage
Each of Modules 3 to 11 ends with the question to require before sign-off, and Module 12 assembles the nine into a review artefact.
Patterns with the trade stated
Around fifty catalog entries, each naming the term it moves and whether it saves once or on every hour, query or run.
What this course helps with
See where a data estate actually costs
Stored, moved and scanned bytes run on three different clocks, and the mechanism that dominates a service is frequently not the one it is named after.
Design it in rather than remediate it
Almost every expensive data decision is cheap when it is taken and paid at a later stage — the course puts the question before the decision.
Cover what the estate-level courses leave short
Warehouse layout, index and vector economics, retention authority and telemetry get a module each rather than a section.
Who this is for
- Data engineers and analytics engineers
- Database, warehouse and platform engineers
- Data architects and technical leads responsible for a data estate
- ML and AI engineers who own retrieval, feature or vector stores
- Assumes working familiarity with data systems; no sustainability background required

What you will work with
The three mechanisms
Why a small hot table can cost more than a large cold archive, and which lever works on each.
The copy count
One 1.2 TB warehouse, nine physical copies, and the policies that created them separately.
The Green Data Blueprint
Four blocks (assessment, measurement plan, pattern register and governance wiring) bound by a traceability test.

01
Why Water, and Why You
Software feels dry, but the buildings it runs in use water for cooling, the electricity it consumes was made using water, and the hardware was manufactured with it. This module shows those three connections and closes the gap between the people who can see the water and the people who change the software.
module-01
02
The Four Layers: building, electricity, hardware, and the stress conversion
This module gives the three ways software uses water their proper names, as the draft SWI specification uses them, and adds a fourth layer that converts litres into how much each litre matters. It ends with the only line of arithmetic in the course.
module-02
03
Consumption and Withdrawal: used up vs borrowed
Water figures come in two kinds, and confusing them is the most common mistake in reading them. This module teaches the distinction between water used up and water borrowed and returned, and the rule that the two are never added together.
module-03
04
Reading a Water Number
This module teaches no calculations. It teaches how to look at any water figure, whether a provider report, a news headline or a colleague’s slide, and know what it does and does not say.
module-04
05
Stress-Adjusted Water: a liter is not a liter
The same liter counts for more where water is scarce and for less where it is plentiful. This module turns that idea into arithmetic using a published factor per place, giving the conversion layer its full treatment at foundation depth.
module-05
06
Small Things That Save Water
The earlier modules built a vocabulary; this one turns it into actions small enough to take this week, organised by role. None of them needs a water meter, a budget or permission to run a project.
