Building Design and Energy Analysis with OpenBuildings

Multidiscipline building design

Design safe, sustainable, and distinctive buildings

OpenBuildings is a multidiscipline building design software that enables BIM workflows to provide information-rich models for the design, analysis, simulation, and documentation of buildings. 

  • computational design and
  • energy services for building performance evaluation
  • 3D modeling environment
  • site context by referencing reality models

With OpenBuildings Designer, you can optimize designs, meet tight deadlines, and avoid errors.

OpenBuildings Designer

Design Buildings and Facilities of any Size

Design MEP Systems
Design complex mechanical, electrical, and plumbing (MEP) systems, including lighting, power, fire detection, fully parametric air-handling, piping, and plumbing systems.

Generate Building Documentation and Reports
Link specifications, engineering calculations, and equipment documentation to your intelligent building model and produce high-quality, reliable, and up-to-date drawings that accurately represent your design.

Visualize Building Designs
Generate 3D images of models, animations with life-like detail, and high-end photo-realistic renderings, which can aid in the further refinement of potential designs.

Analyze Building System Performance
Inform early design decisions by simulating and evaluating real-world building system performances, including conceptual energy analysis to explore peak loads, annual energy calculations, energy consumptions, carbon emissions, and fuel costs.

OpenBuildings Station Designer

Design Rail and Metro Stations

Take on projects from high-speed and commuter to metro and light rail stations. This software even allows for analysis of pedestrian travel paths.

  • Functional space definitions and a catalog of design components are specifically geared to railway station design.

  • GenerativeComponents templates for complex geometry are ideal for designing tunnels and platforms.

  • Create simulation scenarios by defining spaces, activities, passenger characteristics, and operational information such as train timetables to simulate and analyze foot traffic.
