Geometry: The user’s massing is uploaded to the web apps via the SketchUp or Revit plugins. Required inputs: – Building location – Building type Additional inputs, including weather information: Weather data is automatically set based on building location, but this (and other specification values) can be manually overwritten in the graphic user interface via text boxes, sliders or drop down menus
Outputs include: Air Handling Unit Design Airflow Cooling Equipment Design Capacity Heating Equipment Design Capacity Energy Use Intensity Annual Gas Use & Cost Renewable Energy Generated Annual Energy Cost and more. Results can be exported directly to CSV.
RAPID: From an architectural model to key HVAC outputs in under 10 minutes ROBUST: Built on EnergyPlus — the industry standard for building simulation FLEXIBLE: Easily compare massing options, envelope properties, and HVAC design choices “The ability to proactively suggest optimisations to clients and easily react to model iterations will help us differentiate our service in this increasingly competitive market.” John Anthes P.E., Edwards and Zuck Consulting Engineers
