435 Indio Way: Elegance and Simplicity in a Zero Net Energy Office Building


The landmark Zero Net Energy (ZNE) office building at 435 Indio Way, Sunnyvale, CA has been recognized again. This time the stunning remodel received the award for best Sustainable Built Environment Award from Acterra 2015 Business Environmental Awards. The organization is an environmental nonprofit working toward a healthier planet. The honor requires two critical factors; To conserve natural resources and to promote the health and well-being of its occupants.  Previously, this project was a winner of the Silicon Valley Business Journal Structures Awards for Best Reuse/Rehab Project, certainly with more recognition to come.

Given our corporate pedigree of creating vibrant, healthy buildings, SageSpace, a pioneer in user-centric sustainable buildings, presented Hillhouse with a challenge: Create a competitively priced zero net-energy facility from an existing 30,000-square-foot, outdated 1970’s concrete tilt-up building. Our goal was to offer the mid-size tenant marketplace an opportunity to occupy a one-of-a-kind, highly sustainable facility that was previously only affordable to deeper-pocketed corporations.

Knowing that this would be a high risk, high reward project, Hillhouse and SageSpace assembled a cross-functional A-team with Integral Group and RMW Architecture and Interiors and began our calculated next-steps to create a user-centric design and utilize cutting-edge technology. Keeping the tenant experience top of mind, we made sure that while everything inside the open collaboration workspace is aesthetically pleasing, it also serves a functional purpose and enhances the employee experience.

This sustainable renovation incorporated new technologies such as View Dynamic Glass windows, new innovations in thermal cladding, and new thermal bridging techniques that allowed tenants more control over their workspace. The building is also equipped with real-time user interface allowing tenants to customize their work environment, trend energy behavior, and improve performance outcomes.

The result? 435 Indio Way is 100% daylit, 100% naturally ventilated, and the estimated electrical usage for thermal comfort is only 15% of that of a conventional office building the same size. The building’s strong connection to nature and outdoor amenities is showcased by an abundance of natural daylight, fresh air systems, community gardens, edible landscaping, and outdoor meeting spaces.

The 435 Indio Way project conclusively proves that spec office retrofits can be beautiful, functional, energy-efficient and budget conscious. We are delighted to have joined SageSpace in setting the precedent for next-generation ZNE construction in Silicon Valley.
