eQUEST
The QUick Energy Simulation Tool.
Overview
eQUEST is a freeware building energy simulation tool that provides a graphical interface for the DOE-2 simulation engine. It is designed to be used by a wide range of design team members, from architects to engineers, at various stages of the design process. It includes wizards to simplify the process of creating a building model and running simulations.
✨ Key Features
- Building creation wizards (Schematic Design, Design Development)
- Energy Efficiency Measure (EEM) wizard
- Graphical reporting of simulation results
- Based on the DOE-2.2 simulation engine
- Import of building geometry from architectural models
🎯 Key Differentiators
- Free to use
- User-friendly wizards for faster model creation
- Long-standing and widely accepted in the industry
Unique Value: Provides a free and relatively easy-to-use graphical interface for the powerful DOE-2 energy simulation engine, making it accessible to a broader audience.
🎯 Use Cases (3)
✅ Best For
- Energy code compliance (e.g., California Title 24)
- Modeling for utility rebate programs
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Users requiring highly detailed, customized HVAC simulations not supported by DOE-2
- Projects requiring co-simulation with other tools
🏆 Alternatives
While not as flexible or detailed as EnergyPlus, its user-friendly wizards and graphical reports make it faster for standard building energy analysis.
