This 35 story, first class office building in the busy Brickell Avenue business district has been designed by the well known architectural firm of Nichols Brosch Wurst Wolf & Associates of Coral Gables, FL. This project is being submitted for LEED Certification under “core and shell”. It consists of 600,000 sq ft of leasable area with a total enclosed area of 1,000,000 sq ft.
The buildings A/C system consists of 3-820 ton chillers with a supplemental overtime condenser water based A/C system with a capacity of 460 tons. Total cooling tower capacity is 2-2cell cross draft units @ 1460 tons each. This enables the tenants of this office building to procure overtime A/C in 2 ways – either pay the building to operate the chilled water system for their space or tie into the buildings 24 hour 460 ton condenser water cooling system and install their own water cooled A/C units to service 24 hour operations such as data centers or other special areas.
The domestic water system for this project consists of 2 incoming water services. One system serves potable and one serves non potable such as irrigation and cooling tower make up water. All of the A/C condensate is captured and pumped back to the cooling towers as the primary make-up water source. Each system has its own variable frequency drive pumping system. Each tenant has four locations remote from the building core to tie into for executive bathrooms, remote coffee stations or mini kitchens.
The storm drainage system consists of one collection system for the roof and one for the parking garage. Both tie independently into the onsite disposal wells.
Power is provided to the buildings 277/480 volt, 3 phase, 4 wire secondary system via a vault with primary service from Florida Power & Light (FPL). This secondary system emanates from switchgear and is delivered via multiple bus ducts running vertically to stacked electric rooms on the office tower.
The office tenant’s electrical service was sized for 12 watts per sq ft to incorporate lighting, the VAV box heat, receptacle and appliance outlets using a step down transformer at each floor to obtain 120/208 volt, 3 phase, 4 wire services.
The emergency power system consists of 1 – 2250 kw and 1 – 1250 kw generators. These provide power to 1/3 of the buildings A/C system and the entire life safety system, smoke evacuation system and domestic water pumping system. A 10,000 gallon above ground diesel fuel tank enables the building to function for several days during an emergency. All of the buildings lighting (public areas and garage) are controlled via occupancy and daylight sensors.
