415 N Mathilda Office Building
The project transformed a 1970s two-story, 35,000-square-foot athletic club to a Class A office building that produces zero-net energy.
Among the project’s numerous energy-saving and sustainable elements are rooftop solar panels, recyclable materials, skylights to help maximize daylight harvesting and dynamic glass that transitions from clear to dark depending on the sun’s angle to diminish glare, minimize heat gain and energy use, and maintain outdoor views.
The California Energy Commission awarded a $1.5 million grant to the Mathilda project, viewing it as a model for the commercial and financial viability of retrofitting commercial offices to use zero-net energy. This project will be highly documented and measured, and will be used as a template for future zero-net buildings across the state.
Integral Group was part of an integrated project team, collaborating with the developer, architect, and contractor and providing mechanical, electrical and water systems design, as well as energy, daylighting, and envelope modeling, and sustainable design consulting.
