Design day, zone loads, sizing and unmet hours, direct from your energy model

Better Building's Advanced HVAC workflows empower engineers and designers to model intricate HVAC systems efficiently. Utilising EnergyPlus™, it offers both predefined templates and detailed component-level customisation, accommodating a wide range of system types and configurations. Users can define system boundaries, adjust parameters, and simulate performance to ensure optimal design and operation.
EnergyPlus™ Simulation Integration

All HVAC systems are natively compatible with EnergyPlus™, ensuring accurate performance modelling.

HVAC Template Library

Quickly assign predefined system templates such as Ideal Loads, VRF, or Packaged VAV to suit project requirements.

Component-Level Customisation

Modify individual system components like coils, fans, and heat exchangers for detailed performance control.

Zone-Level HVAC Assignment

Assign HVAC systems on a zone-by-zone basis to reflect real operational strategies and zoning schemes.

Flexible System Boundaries

Define mechanical zones, supply and return paths, and equipment boundaries to suit various system configurations.

Load Profile Integration

Integrate heating, cooling, ventilation, and occupancy profiles to simulate dynamic loads over time.

Unmet Hours

Spot comfort issues early with clear visualisations of unmet heating and cooling hours.

Zone Loads

Understand demand patterns with detailed breakdowns of zone-level heating and cooling loads.

Design Day Review

Quickly assess system sizing with easy-to-read outputs from critical design day simulations.
