Where ClimateStudio is strong

  • Fast daylight and energy simulation on Rhino geometry.
  • Climate analysis next to simulation: temperature, humidity, wind, radiation and UTCI on site.
  • A searchable library of more than 30,000 weather files.

Where C4B takes a different approach

  • Runs in any browser, on Mac or Windows, with no Rhino licence.
  • Starts from an address, and projects add site-specific reanalysis data instead of choosing a station file.
  • Adds future climate scenarios, Köppen-Geiger zones to 2100 and a PDF climate report for the brief.

ClimateStudio may suit you better if

  • You need daylight, glare or energy simulation on your Rhino model.
  • Your team works on Windows with Rhino.

C4B may suit you better if

  • You work on a Mac or without Rhino.
  • You need the site-climate brief before modelling starts.
  • You want future climate and a report the whole team can read.

Frequently asked questions

Does ClimateStudio run on Mac?

Its documentation states that ClimateStudio requires Windows and does not currently run on macOS. C4B runs in any modern browser.

Does C4B do daylight simulation?

No. C4B focuses on climate, comfort and preliminary energy analysis for a site; it does not simulate daylight or glare.

Can I use C4B weather files in ClimateStudio?

C4B's EPW downloads (Technical and Enterprise plans) are standard EPW files, the weather format ClimateStudio works with.
