ABOUT WEBER THOMPSON
Founded in 1987, Weber Thompson is a full-service architecture, interior design, landscape, and planning firm.
We believe that good design includes green building practices – integrating disciplines that create buildings, interiors and places that are not only good for the environment and community, they are essential to the health and well being of users, are easier to market, more efficient to operate and help “green” the bottom line.
Since our inception, green practices have been at the core of what we do. When we moved into our LEED Platinum Certified offices over eight years ago, we solidified our commitment to sustainability.

ARCHITECURE AT ZERO
• The 2015 competition: mixed-use student housing site on the UCSF Mission Bay campus
• Weber Thompson partnered with energy consultants at WSP Group to empirically demonstrate that the design would meet ZNE
• In our concept, the budget for net-zero energy is tracked and displayed in real time – students and their families actively manage their energy with continual feedback
LOT SIZE: 113,000 SF
BUILDING SIZE: 418,320 SF
LOCATION: SAN FRANCISCO, CA
PROJECT TYPE: RESIDENTIAL: MULTIFAMILY
Architecture at Zero is a zero net energy design competition open to students and professionals worldwide, engaging architecture, engineering, planning students and professionals in the pursuit of energy efficient design.

THE DESIGN TEAM RESEARCHED STUDENT DEMOGRAPHICS AND INTERVIEWED STUDENTS, PROVIDING INSIGHT INTO OCCUPANCY/USE PATTERNS. FROM THERE, FUTURE RESIDENTS WERE DIVIDED INTO 3 PROFILES; WHICH WERE CHARTED COMPARED TO DEFAULT RESIDENTIAL SETTINGS IN THE ENERGY MODEL. RESULTING IN A WEIGHTED AVERAGE THAT REFINED ASSUMPTIONS OF OCCUPANCY AND LIGHTING PATTERNS IN THE RESIDENTIAL UNITS.

Thanks to preservation incentives, the Sunset Electric Company’s legacy and home lives on. Red brick terracotta emblems with the Sunset Electric Company logo have been restored to their original glory, and continue to decorate the building’s facades nearly a century later.
PRESERVING THE PAST
SUNSET ELECTRIC – SEATTLE, WA
The courtyard is a key component of the building’s dramatic energy savings because it eliminates common area energy use. The secondary benefit is that interior circulation is pleasantly daylit and provides natural daylighting and ventilation to residential units. See chart at right for other major reductions.
