Environmental simulations

/simulate extracts geometry from the connected model and runs sun hours, shadow, sky exposure and solar radiation locally. Optional EPW file or URL. If the weather file fails, Urbanaut will not silently fall back to a clear-sky study. You choose that recovery.

Reading results

• Sun hours: hours of direct sun on the receiver mesh, for the date and hours you set.
• Shadow: hours in shade on those receivers.
• Sky exposure: the fraction of the sky vault visible, not a daylight-factor certificate.
• Solar kWh/m²: radiation on surfaces; roof PV is an optional layer of that study.

Overlays are a design aid. They are not a statutory energy model or a substitute for a measured survey.
