Commercial and public buildings increasingly demand lighting strategies that balance visual comfort with architectural impact. In this workshop, ERCO explores how precise photometric tools transform expansive volumes into human-centric environments. We will move beyond simply "filling a room with light" to focus on vertical illumination and beam control that defines the space.

Participants will evaluate the unique requirements of high-ceiling atriums, transit hubs, and galleries. Through case studies, we demonstrate how to marry high-performance LED technology with long-term operational value, ensuring that even the most cavernous spaces feel intimate and purposeful.
