Bentley Systems releases software for energy design and simulation

Bentley Systems introduced its Energy Performance Series; software for building energy design, analysis, and simulation.


The Bentley program includes Bentley Tas Simular V8i, Hevacomp Simulator V8i, and Hevacomp Mechanical Designer V8i. The software provides to tools to design, analyze, and simulate building energy systems and ensure that the buildings continue to perform as predicted.

Bentley’s Energy Performance Series uses two differently purposed simulation engines to provide building energy design and analysis: the EnergyPlus engine, the standard developed by the DOE, and the independently developed Tas high-speed engine. The Hevacomp simulation engine is optimized for typical project configurations and to ensure compliance with regulatory requirements and industry best practices.

Users of the software can create 3D analysis models from 2D floor plans with detailed thermal properties. The software predicts annual energy consumption, carbon dioxide emissions, and operating costs.

The software supports industry standards such as ASHRAE Standard 90.1-2004, ASHRAE Standard 140-2004 (BESTEST Models), LEED Energy Atmosphere Credit 1, U.K. Building Regulations Part L2, ISO, ANSI/ASME, and CIBSE. Bentley’s Energy Performance Series maximizes point accumulation under LEED Energy and Atmosphere Credit 1.
