Greenbuild Session A09 – Daylighting Simulation at Four Architecture Firms

This is a very interesting session from last years Greenbuild on how four leading architectural firms tackle the issues around understanding daylight metrics and informing design decisions accordingly. How do firms start a daylight simulation program in-house, how do they run it, integrate with project schedules, and use it to make better design decisions? Leading...
Webinar - The Bullitt Center: Meeting the Living Building Challenge

Webinar – The Bullitt Center: Meeting the Living Building Challenge

The Bullitt Center, a six-story heavy timber building recently completed in Seattle, is predicted to be the world’s most energy-efficient commercial building. It has been designed to last 250 years and to achieve the highest benchmark of building sustainability—Living Building Challenge (LBC) certification. A performance-based certification program, the LBC requires buildings to be evaluated after...
