PROGRAM
CLADDING
Being on a major street the buildings runs parallel with Broadway. This is also beneficial with the orientation due to minimal exposure on the west side. The office and restaurant are two distinct programs that share a common ground entry.

Proposal B
Building is designed with an emphasis on Broadway. One of the main features is a cantilever on the northwest side. With an opportunity for a roof top garden on top of the first floor that would be utilized space for mix use/retail. Shafts are place on East and West entrances to access office wings. Second to sixth floor are designated for office space. Cladding accompanied with cantilevered shading devices were installed on north and west sides of the building.

Proposal C
The massing strategy of the project contrasts and breaks the rigid grid of the city. Extremities emanate from the main body, diverge in different angles, providing dynamic views. Concrete, glass, and metal paneling work in conjunction to efficiently regulate the building’s climate. A programmable louvered facade is contemplated as well to naturally regulate energy and take advantage of the weather conditions of the area.

Selected Design
Proposal C was the more efficient proposal because it takes advantage of solar heating. The building generates an enclosed definition of the site, which creates a plaza like environment for the roject. Natural lighting is maximized as the sun’s southern arc travels from east to west. Two service cores are implemented, allowing accessible placement of the fire stairs in order to meet ADA requirements.

Sprinkler system is no more than 300 ft. to each exit. The fire rating for each structural wall is three hours. There is a seperate core fire escape on the east wing that allows for emergency egress for restaurant and retail spaces. 6” thick concrete walls provide the stairway with a fire resistance rating greater than 4 hours.

Steel framing provides necessary strength for building height. Concrete on steel decking keeps the weight from each floor minimal on structural members while supporting dead loads. Open web joists are also used to distribute plumbing and duct work throught the floors.

Heating and cooling system Variable air volume system was chosen because it is the most versatile and most widely used system among large buildings with multiple programming. This system consists of air that is conditioned by a central source, which is usually located in the basement. The vents are divided into gain and supply systems, which help circulate the air through out the building. This system also allows each zone to be controlled by thermostat, allowing different temperatures throughout the different zones of the building, while still using one central system. The fan used in the VAV revolves at a constant ratio, providing a constant work environment for the occupants.

vertical supply shaft
vertical exhaust shaft
Advantages Inexpensive to install, as well as low cost maintenance. This helps to keep the operational cost of the building down and at the same time allows independent zones to be maintained. Helps to control and maintain separate zones, this system is ideal because of the buildings multipurpose use and still having the ability to control multiple zones. Minimizes system noise
Zoning
horizontal return ducts
Our building is defined by two major zones, office space, and restaurant space. The main supply and return shafts run vertically next to each other to provide the air flow required for the system to function properly. From the main vertical shafts, which are the largest in profile area of the ducts, the secondary system of ducts branch out. The exhaust ducts have a larger profile than the fresh air supply ducts, the reasoning behind it is that the exhaust ducts run mainly as a single line along the footprint of each floor, while the supply ducts wrap the perimeter of the floor.

Sizing for air handling Cooling air volume in CFM: 30,000 (m³/sec) Area of main supply or return ducts: 20 ft² Area of branch supply or return ducts: 30ft² Area of fan rooms: 1,000ft² Area of fresh air louvers 90ft² Area of exhaust air louvers: 70ft²

Chiller
A dual compressor chiller can also provide installed costs savings of up to 35% compared to installing two separate chillers. •Eliminates piping to the second chiller and to additional pumps •Fewer valves and controls •Less rigging costs •Reduced control wiring The redundancy of two of everything connected to the evaporator and condenser enhances reliability. If any compressor component fails, it can be removed or repaired without shutting down the other compressor. And there's automatic back-up with at least 60% of the chiller design capacity available on single circuit units and 50% on dual circuit units. Centrifugal compressors have few moving parts which make them a favorite in the industry.

Condenser Boiler Provides maximum flexibility for larger facilities with enhanced efficiency. The larger capacity design allows the most effective installation by using fewer units as opposed to banks of smaller boilers, thus reducing cost, complexity, and maintenance. •Fully condensing with up to 98% efficiency and 5:1 turndown •Ultra-low emissions •Reduce energy consumption by as much as 40–50% compared to traditional non-condensing boiler systems •No minimum return water temperature for maximum efficiency and reliability •Dual temperature returns for system design flexibility •Up-front capital cost is reduced by installing fewer larger-capacity boilers versus many smaller boilers •Fully integrated system includes boiler, burner, and controls for multiple lead/lag configuration

Counter flow Cooling Tower CMC and CMD cooling towers work on the principle of counter flow. This means that the water flows down while the air is pulled upwards by a fan. As the water flows further through the system, the air it encounters is fresher, in other words cooler and less saturated with moisture.
