Google Caribbean

The Google Caribbean campus includes two office buildings (100 and 200 Caribbean) totaling 536,750 and 505,140 square feet respectively. Also included is a four-level 1,420-car concrete parking garage (300 Caribbean), two bridge crossings over a tidal drainage channel, and an ecological revitalization of the channel (500 Caribbean). 
 

The office buildings have a stepped configuration, with each level smaller than the one below. The north facade features a sloping, stepped green roof that is accessible from grade up to level five. 

The southern area of the project will resemble a plaza and include a private shuttle drop-off, bicycle storage, dog park, and other amenities. 
 

The Caribbean facilities are conditioned by custom air handling units utilizing chilled and hot water, chilled water fan coils, and transfer fans. A district utility plant distributes chillers chilled and hot water facility level pump houses and transfers thermal energy via plate and frame heat exchangers to all AHUs, chilled water fan coils, and kitchen heat rejection equipment. An underfloor air distribution system provides localized distribution in most areas. Exhaust systems are provided for specific spaces, and electrical and IDF rooms are served by chilled water fan coils. 
 

The electrical project scope includes two emergency generators with associated ATSs, electrical distribution through a 12kV switchgear and local substations at each facility, grounding, and enlightened lighting and receptacle controls with daylight harvesting for energy efficiency. 
 

An approximately 2 megawatt photovoltaic array consisting of over 4,100 panels is mounted over the parking garage.  An approximately 2 megawatt battery energy storage system charges excess power generation by the array for discharge when needed. 
 

Each facility is fully submetered for any energy load consuming more than 10% of the total building usage.  Potable water and recycled water is metered as well.  Consumption is segregated by building and use category for benchmarking.  Data is integrated across multiple systems for analysis.
