Building energy modeling predicts building energy consumption, CO₂ emissions, peak demands, energy cost and renewable energy production.

Whole building energy simulation analysis capabilities of the IESVE software tools covers a wide range of assessment types from energy efficiency, comfort, ventilation, HVAC performance and optimization. Design for the future with low impact energy systems and strategies.

• Integration: 1-way and 2-way model simulation links with other IESVE Applications & simulation engines for solar, daylight, airflow and HVAC.  
• Captures building performance metrics for energy, water, carbon, cost, comfort, loads and more. 
• Extensive range of predictive simulation results variables for buildings, systems, zones, room and surfaces. 
• Simulation results available for annual, monthly, hourly, and sub-hourly analysis. 1-minute simulation time-step available. 
• Assess thermodynamic performance of active and passive systems, with the ability to perform multiple simultaneous simulations in parallel using the Parallel Simulation Manager.
• APACHE automates the creation of energy code baseline models for compliance comparisons. E.g. ASHRAE 90.1, NECB, Title 24, IECC, etc. 
• ASHRAE 140 Validated and EPAct Approved
• Export results to MicroFlo as boundary conditions for detailed CFD analysis.
