6:00 PM Seminar – Day to Night: George Loisos, Principal, Loisis + Ubbelohde


As clients increasingly demand connection to diurnal rhythms, a better understanding of daylight and how it interacts with electrical lighting becomes crucial. This presentation will review strategies for designing electric lighting in conjunction with daylighting; methods to quantify and evaluate the integration of the two; and what happens when you stretch these ideas to their limits.

Learning Objectives:

Participants will learn:

1.     How to understand what daylight can deliver to occupants

2.     How to recognize the potential coordination of daylight and electrical lighting for occupant comfort

3.     How to be aware of current research on glare and the lack of good glare standards

4.     How to understand the limits of beam daylighting and why one should be very careful

Approved for 1 IES CEU and 1 AIA HSW LU

George Loisos
George is a registered architect and a founding partner of Loisos + Ubbelohde, an unconventional practice that brings research methods and advanced simulations to a wide range of architectural projects. L+U has pioneered new methods of analysis in daylighting, lighting design, solar reflectance and convergence, energy conservation and production, thermal comfort and natural ventilation. His projects have received 70 AIA awards, four AIA/COTE Top Ten Green Projects, and sixteen LEED platinum certifications. Mr. Loisos previously led research programs in building energy use at the University of California, San Diego, and the University of Minnesota, Minneapolis, and served as the architectural program coordinator for PG&E, directing projects in daylighting design and productivity. As project manager and research lead for the California Energy Commission, he coordinated research and product development on energy efficient lighting and lighting controls. Recent work with solar convergence issues include the Vdara Death Ray in Las Vegas and 20 Fenchurch in London, as well as predictive modeling and design for projects in the U.S. and China.
