Industrial HVAC Energy Architecture

This system view maps how industrial HVAC loads are supplied, balanced, and controlled across grid power, rooftop PV, and battery buffering. It visualizes the multi-layer energy distribution and control logic used to keep thermal performance stable under fluctuating demand and renewable input.

Prototype environment. Illustrative data.

What it visualizes

  • •Cooling/heating/renewable energy flows across layers
  • •Load and peak capacity constraints
  • •EMS/BMS control points and failover priorities
  • •HVAC core execution layer (AHU, heat pump, chiller)
  • •Zone-level load allocation and criticality

Used for

  • •Validating hybrid energy architecture
  • •Sizing conversion + buffering strategy
  • •Mapping integration dependencies and control loops
  • •Tender-ready system documentation
