Low PUE, Low Carbon, High Performance—Backed by Evidence
Green Data Centers cut energy, water, and carbon without sacrificing performance or uptime.
SolveForce designs and operates sustainable DCs—on-prem, edge, and colocation—with liquid/air hybrid cooling, renewable energy, heat reuse, carbon-aware scheduling, and auditable metrics (PUE, WUE, CUE, CFE%) wired into your DCIM and SIEM.

🎯 Outcomes (Why a Green DC with SolveForce)
- Energy efficiency with provable PUE and workload right-sizing (CPU/GPU utilization ↑, waste ↓).
- Water stewardship via low-WUE designs (air-cooled, adiabatic controls, or liquid loops with minimal loss).
- Carbon reduction through CFE%↑ (carbon-free energy share), PPAs/RECs, and carbon-aware workload scheduling.
- Thermal headroom for AI density—rear-door heat exchangers (RDHx) or liquid-to-chip cooling.
- Audit-ready reports: GHG Protocol (Scopes 1/2/3), ISO 50001/14001 alignment, CDP/TCFD exports.
🧭 Scope (What We Build & Integrate)
- Power — high-efficiency UPS (double-conversion/eco modes), A/B PDUs, busways; metered outlets.
- Cooling — hot/cold aisle containment, free cooling/economizers, adiabatic options, RDHx and direct-to-chip liquid for dense racks.
- Renewables — on-site PV + storage where viable; off-site PPAs/VPPA, RECs, hourly CFE matching.
- Fabric — EVPN/VXLAN leaf/spine, QoS lanes; MACsec/L1 encryption by policy. → /networks-and-data-centers • /encryption
- Compute/Storage — virtualization/K8s density, GPU scheduling, NVMe tiers; cold/archival offload. → /kubernetes • /bare-metal-gpu • /san
- Heat reuse — hydronic loops to building heat or district systems, ERE (Energy Reuse Effectiveness) monitoring.
- Observability — DCIM + power/thermal/carbon feeds; SLO dashboards; SIEM/SOAR export. → /noc • /siem-soar
🧱 Building Blocks (Spelled Out)
- Airflow & Thermal
- Hot/cold aisle, blanking panels, brush grommets, return-air capture; elevated setpoints within ASHRAE envelopes.
- RDHx for 20–60 kW/rack; liquid-to-chip for 60–100+ kW/rack GPU pods.
- Energy & Carbon
- High-efficiency UPS (96–98%); transformerless designs; staged eco modes with fail-safe gates.
- CFE strategy: on-site solar + ESS (where feasible); off-site PPA/VPPA; hourly matching where available.
- Water
- Preference for air-cooled or hybrid with adiabatic only in peak conditions; closed-loop liquids to minimize make-up water.
- Workload Efficiency
- Right-size CPU/GPU; autoscale; bin-pack via K8s/Slurm; power capping/DVFS; carbon-aware scheduling (shift non-urgent jobs to greener windows).
- Storage hierarchy: NVMe scratch → active SSD → object/archive; lifecycle & dedupe.
- Circularity & Materials
- Low-embodied-carbon materials, modular builds; certified e-waste recycling, component harvest, secure wipe.
