Green Data Centre Design & Modernisation
Design for low PUE and WUE from day one — retrofit the estate against measurable targets.
New-build, colocation and retrofit facilities engineered for low Power Usage Effectiveness (PUE) and Water Usage Effectiveness (WUE) — advisory, design, implementation, commissioning and lifecycle support. Containment, free cooling, high-efficiency UPS, intelligent power distribution and DCIM instrumentation are engineered in from the first drawing.
Owned, colocation and hybrid data centres across temperate and tropical climates.
Design and modernise against measurable PUE and WUE targets, not headline claims.
Designs prepared with reference to Uptime Institute Tier II, III and IV and TIA-942; certification coordinated separately with the applicable authorised body.
What we deliver
Data centre advisory & feasibility
Site selection, climate analysis, capacity forecasting and Tier and rating assessment — the engineering-led feasibility work that shapes a defensible business case before design begins.
PUE-led design targets
PUE targets established per project according to climate, load profile, resilience requirement and facility type — free cooling, economisers and airflow discipline engineered in from concept, not bolted on later. Performance depends on utilisation and operating conditions.
Hot & cold aisle containment
Full containment strategies, blanking discipline, chimney cabinets and floor-tile management — the fundamentals that consistently outperform equipment upgrades on cost-per-kW-saved.
Precision & free cooling
Variable-speed CRAC and CRAH, adiabatic and evaporative options, chilled-water optimisation and dry-cooler selection matched to climate, load profile and reliability targets.

High-efficiency UPS topologies
Modular, transformerless UPS with eco-mode where appropriate — sustaining high efficiency across the operational load range from vendors such as Schneider, Vertiv, Eaton and ABB.
Renewable & PPA readiness
On-site solar, battery energy storage, PPA and REC integration — grid-carbon-aware operations without compromising Tier reliability or SLA commitments.
Intelligent power distribution
Metered and switched rack PDUs, branch-circuit monitoring and busway distribution — full sub-metering so every watt is attributable and every capacity decision is data-driven.
CFD & thermal modelling
Computational fluid dynamics for airflow, hot-spot elimination and containment validation — design decisions proven with modelling before capital is committed.
Water usage (WUE) minimisation
Water-side economiser selection, cooling-tower blowdown strategy and dry-cooling alternatives — WUE reported and managed alongside PUE, not treated as an afterthought.
DCIM instrumentation from day one
Sensor layout, sub-metering topology and DCIM platform — Schneider EcoStruxure, Vertiv, Sunbird and Nlyte — selected during design so commissioning delivers a fully instrumented facility.
AI & high-density readiness
Design for rack densities of 30–100+ kW with liquid cooling, rear-door heat exchangers and immersion options — planning for GPU and accelerated compute workloads.
Data centre modernisation & retrofit
Consolidation, refresh and retrofit programmes that migrate workloads, uplift power and cooling and improve PUE without disrupting production — delivered as a phased, risk-managed project.
Why teams call us
- Ageing facilities run at low utilisation
Legacy cooling, oversized UPS and low IT load push PUE well above modern benchmarks — energy cost and carbon suffer together.
- Airflow discipline is missing
Containment, blanking and floor-tile management are inconsistent, so cooling capacity is wasted before it reaches the load.
- Capacity decisions are made without data
Rack, power and cooling capacity is estimated rather than measured because sub-metering and DCIM instrumentation are incomplete.
- High-density workloads outrun the design
GPU and accelerated compute racks exceed the facility's original power and cooling envelope, creating hotspots and stranded capacity.
Our approach
A data-centre efficiency lifecycle covering feasibility, design, implementation, commissioning and modernisation across new-build, colocation and retrofit programmes.
- Assess
Feasibility, site climate, capacity forecast, Tier requirement and current PUE/WUE baseline where the facility already operates.
- Design
Containment, cooling, UPS, power distribution, renewable readiness, CFD-validated thermal envelope and DCIM instrumentation.
- Implement
Deploy, integrate and commission the facility — including staged retrofit programmes that keep production running.
- Support & Optimise
Scheduled efficiency reviews, DCIM tuning, capacity planning and refresh planning under an agreed service scope.
End-to-End IT Integration and Support
From assessment and solution design through implementation, remediation, ongoing support, and lifecycle optimization.
Fix What's Broken — Remediation Sprints
Carbon reporting deadline looming, PUE stuck too high, no baseline for Scope 2/3 IT emissions, or an ESG audit finding open? We run fixed-scope sustainability remediation sprints against a defined outcome.
- Energy, PUE and carbon baseline: metering, data quality and reporting fixes
- Data-centre and workplace energy-optimisation quick wins
- Circular-IT, refurbishment, secure disposal and Scope 3 supply-chain data
Support & Maintenance — AMC-Backed
Run sustainability as a program — continuous carbon accounting, optimisation and reporting under a Jiva managed service.
- Managed carbon and energy reporting aligned to GHG Protocol and ISO 14064
- Quarterly optimisation reviews across data-centre, workplace and cloud
- Circular-IT operations: asset refresh, refurbishment and certified disposal
