Lighting

The Brooklyn Health Center is lit entirely using LED fixtures. The fixtures selected use very little energy, contributing to the efficiency of the building. The lighting in the exterior plaza of the building uses solar power, to again reduce the energy use of the building. The building uses LED troffer fixtures, recessed linear slot fixtures, round downlights, surface mounted linear fixtures, round pendants, cove lights, wall grazers, and decorative pendants to light the interior of the building. While the exterior of the building utilizes LED strip lights, pole fixtures, in-grade tree uplights, accent fixtures, floodlights, and jelly jar fixtures. The interior fixtures also have a coordinated CCT (correlated color temperature) of 3500K, while the exterior lights utilize a slightly warmer CCT of 3000K. Most of the fixtures in the building use 0-10V dimming ballasts that will be able to adjust the light levels to the most appropriate level for the space. 

 

Electrical

The building is fed via two service entries with 100KAIC at 208/120V, 3 phase power from Con Edison. Once it enters the building the power is distributed via a number of distribution panels, to panel boards spread across all the floors, where it is then delivered to the load. The building is extremely efficient, and falls well below the LPD allowance set forth. The facility has a 400kW emergency generator in the building penthouse. 

 

Mechanical

This facility uses two 25,000 CFM energy recovery units. The building also has two air handeling units that supply 10,000 CFM and 3,000 CFM to the building. The entire building utilizes exhaust and ventilation fans that are VFD. The main cooling for the building is produced by a 3 cell cooling tower on the roof that produces 56,000 CFM per cell. The building has a condensing firetube hot water boiler that uses natural gas to supply hot water to the building. This facility also has plate and frame heat exchangers in the penthouse. 

 

Structural 

The Brooklyn Health Center uses a steel moment frame and braced frame for its lateral system. The moment frame of the building span in both orthagonal directions. This building also uses a steel gravity system with 6-1/4" LWC slab on 3" 18 guage LOK composite floor deck with 6 x 6-W5.4 x W5.4 WWR. The foundation uses piles, connected by grade beam, to penetrate the bedrock below.  The foundation concrete has a strength of 5000 psi while the above grade concrete has a specified strength of 4000 psi. The framing of the building is such that the beams span the long span and the girders span the short span of a typical bay. 

 

Construction

The building is still under construction and is currently scheduled to be finished in the winter of 2016. The delivery mehtod was Guaranteed maximum price, and the construction was done by Skanska. The total building cost at this point is estimated to be $120,000,000, and is targetting a LEED silver rating. 

 

Fire Protection

This facility uses sprinklers on all floors for active fire protection. The sprinklers are a mix of wet, dry and pre-action, and non-ferrous. The sprinkler has a main automatic fire pump that pumps 750 GPM, and a jockey pump that pmps 20 GPM. There are also multiple fire hose valves on each floor for fire dept. connection.

 

transportation 

The vertical circulation in the building is served by 5 pedestrian elevators and 1 service elevator. There are also two sets of fire stairs on the south side of the building. 

 

 

Telecommunications 

Voice and data outlets are built into the walls of the building in either single, duplex, or quadruplex wall stations. These are placed appropriately to provide an adequate number of access points for phones and data access. 

 

Special Systems 

The security of the building is upheld by numerous CCTV cameras strategically placed throughout the building. There are also doors with card readers to restrict access to floors and areas that need to be secured. The circulation areas are also equipped with motion detectors that will activate at a designated time when the areas are supposed to be vaccant.
