The 343 Second Street project for the Packard Foundation is designed to achieve Zero-Net-Energy and LEED Platinum certification. With an emphasis on replicability, the high performance office building will house 120 staff members, reduce energy demand over a conventional building by 50% and supply the energy needed with on-site photovoltaics. The two-story building complex is oriented with the Los Altos street grid off-cardinal and contains a large landscaped courtyard that brings light and sun to the offices and meeting rooms. As members of the design team, Loisos + Ubbelohde provided site shading studies, daylighting design and simulations, shading design control protocols and glass specifications. The shading design and controls respond to the varied orientations and internal space planning to deliver optimal daylight and visual comfort.
