Webinar Description

Qubu Ultralight is a high-speed, and easy-to-use software, designed for the Direct Sunlight and indirect Daylight Factor evaluation of buildings and urban zones that can seamlessly integrate into the regular design processes of sustainable and compliant buildings.

During the webinar, we will discuss how and why to use Ultralight in Grasshopper to achieve accurate and faster daylighting analysis, aligning with Qubu's mission to help architects and real estate developers create better, faster, and more sustainable residential buildings.

Within one hour we will setup a proper scene for simple, fast and accurate daylight analysis with Ultralight for Designers. We will measure Direct sunlight and Daylight factor in multiple apartments, evaluate and interpret the results. We will also discuss advanced measurements and evaluations that can be performed with the Ultralight for Specialist.
