Objective (Sample)

Reduce AC-to-DC conversions across campus to improve energy efficiency, lower costs, and enable smart infrastructure.

Why This Matters

Every AC-to-DC conversion introduces energy losses (5–20%) and heat, increasing HVAC loads and operational costs. By minimizing conversions and moving toward direct DC distribution, schools can:

In parallel, schools can reduce the network side of energy waste by simplifying how connectivity is distributed. Architectures like Passive Optical LAN (POL) reduce the number of intermediate, always-on switches and telecom closets needed across campus—cutting electrical draw and lowering cooling demand in the spaces where network gear typically accumulates.

  • Save energy and reduce carbon footprint.
  • Simplify infrastructure for IoT and smart devices.
  • Improve resilience and safety with modern DC systems.

Key Results

  1. Energy Efficiency
    • Achieve 8–13% reduction in ICT-related electricity use by eliminating redundant AC/DC conversions.
    • Reduce HVAC load in network closets by 10–15% through lower heat output.
  2. Operational Savings
    • Consolidate UPS systems to centralized DC architecture, cutting UPS maintenance costs by 70–78%.
    • Free up at least 2 network closets for repurposing by removing excess conversion equipment.
  3. Sustainability
    • Lower lighting energy consumption by 15–30% using PoE/DC-powered LED systems.
    • Reduce campus carbon emissions by 20 metric tons annually through improved efficiency.
  4. Resilience
    • Enable 2–4 days of critical load support during outages with integrated DC storage and solar PV.
    • Implement Fault Managed Power Systems (FMPS) for safe high-voltage DC distribution.

Initiatives

  • Deploy DC microgrid pilot in one building.
  • Transition PoE lighting and IoT sensors to DC power.
  • Integrate solar PV and battery storage without inverter losses.
  • Train facilities team on DC safety standards (UL 9540A, NFPA 855).
