Assessment workspace
A guided workspace for building evidence-backed, reviewable sustainable digital architecture decisions.
Studio operationalizes the assessment and governance concepts described in the SDAF Enterprise Integration Playbook.
Learn SDAF through decisions
SDAF Studio helps you compare functionally equivalent options, understand what the evidence supports and create a recommendation that remains reviewable.
A summary of the record—not an automated recommendation.
Choose where to start
Explore a complete decision record, inspect its assumptions, or load it into the guided assessment. These are constructed scenarios, with open verification conditions.
Server refresh
Lower electricity use can conflict with capital cost and near-term manufacturing impact.
3 years · Conditional preference: A
B energy: -52.4% · TCO: 50.9%
A: 12 × 350 W; B: 8 × 250 W. PUE 1.4 / 1.4; 8,760 hours/year. Grid factor 0.08 kg CO₂e/kWh. All values assumed.
Cloud migration
Test service equivalence, allocation and utilization before concluding that cloud is greener.
3 years · Conditional preference: B
B energy: -46% · TCO: -24.2%
A: 4 × 250 W; B: 4 × 180 W. PUE 1.6 / 1.2; 8,760 hours/year. Grid factor 0.25 kg CO₂e/kWh. All values assumed.
Laptop life extension
Operational savings alone may not justify a refresh; reliability remains a release condition.
2 years · Conditional preference: A
B energy: -42.9% · TCO: 206.4%
A: 300 × 35 W; B: 300 × 20 W. PUE 1 / 1; 2,000 hours/year. Grid factor 0.25 kg CO₂e/kWh. All values assumed.
Scope 2 versus lifecycle
The same server inputs support different conclusions when the decision boundary expands.
3 years · Conditional preference: A
B energy: -52.4% · TCO: 50.9%
A: 12 × 350 W; B: 8 × 250 W. PUE 1.4 / 1.4; 8,760 hours/year. Grid factor 0.08 kg CO₂e/kWh. All values assumed.
Realistic reference assessment, not a verified client case study. Every numeric input is a constructed planning assumption, not a measurement, supplier quote or published factor. Method references explain the approach and do not substantiate these input values. No implementation or approval is claimed.
