Strategy, Baseline & Metric Architecture
- Sustainability strategy aligned to asset-lifecycle, tenant mix, regulatory jurisdiction, and owner commitments (SBTi, Net Zero, Climate Neutral Data Centre Pact, national roadmaps)
- KPI framework design against EN 50600-4 and ISO/IEC 30134 harmonised definitions — PUE (4-1), WUE (4-9), CUE (4-2), ITEEsv / ITEUsv, ERE, ERF, renewable-energy factor
- Baseline measurement methodology and boundary definition — the single most common failure point in regulated disclosure is a boundary that cannot be defended
- Scope 1, 2, and 3 GHG accounting framework — including embodied carbon in construction, refrigerants, fuel, and upstream grid carbon intensity
- Data architecture for sustainability reporting: metering granularity, sensor placement, retention, and auditability
Design-Stage Sustainability Engineering
- PUE and WUE target-setting against climate zone, cooling architecture, and workload profile — a PUE number is only credible if the boundary and measurement method are declared
- Climate-zone analysis and free-cooling hour projection; wet-bulb profile driving WUE envelope
- Thermal architecture selection from a sustainability lens — air, RDHx, D2C, immersion, hybrid — quantified across energy, water, refrigerant, and embodied-carbon footprints
- Electrical architecture efficiency: transformer class, UPS topology and eco-mode economics, and partial-load operating profile
- Refrigerant and fluid selection against the EU F-gas Regulation, PFAS trajectory, and national environmental permits
- Embodied-carbon analysis for construction and major equipment against EN 15978 / EN 15804 methodology
Heat Reuse Feasibility & Offtake Engineering
Waste-heat availability characterisation: return-water temperature, flow, seasonal variability, and reliability under AI load variance
Offtake market analysis: district-heating networks, greenhouse agriculture, adjacent industrial processes, residential developments, swimming pools, aquaculture, or direct-use industrial offtakes
Temperature-lift strategy: heat-pump integration, secondary heat-exchange, and hydraulic interface design between DC secondary loop and offtake network
Regulatory and contractual structuring: long-term offtake agreements, pricing mechanisms (energy-content, avoided-cost, regulated tariff), and regulatory consent pathways
Integration with EU EED Article 26 (waste-heat utilisation obligations for new and refurbished DCs above 1 MW in EU jurisdictions) and the EU Taxonomy heat-reuse criteria
Economic feasibility: capex, opex, discount rates, regulated return, and sensitivity to offtake-network counterparty risk
Engineering integration: reserve-capacity strategy during AI load transients, failover architecture, and protection of DC thermal envelope against offtake-network faults
Water Stewardship
- WUE baseline and forecast against EN 50600-4-9 and ISO/IEC 30134-9
- Cooling-water source strategy: municipal, non-potable, recycled, atmospheric (ambient air), closed-loop, and hybrid
- Water-scarcity risk assessment — site-level water-stress rating (WRI Aqueduct / WWF Water Risk Filter), seasonal availability, and permit-capacity constraints
- Evaporative vs non-evaporative cooling trade-off against PUE-WUE curve and CSRD E3 disclosure
- Blowdown, reclamation, and zero-liquid-discharge strategy where regulatory or permit conditions require
- Water-permitting and stakeholder-engagement strategy in water-stressed metros (GCC, India, Southern Europe)
Renewable Energy & Carbon Strategy
- On-site and off-site PPA structuring — physical, financial, virtual — coordinated with §4.2 Power
- 24/7 carbon-free energy (CFE) strategy vs annual matching; granular-certificate (GO, REC, I-REC) trading strategy
- Embodied-carbon reduction strategy across structure, mechanical, electrical, and network equipment
- Carbon-offset quality evaluation and disclosure risk: voluntary market scrutiny, additionality, permanence, and CSRD-alignment
- Scope 3 supply-chain engagement strategy — the discipline where most operators are most exposed to disclosure risk
