Building Enclosure
-
Building façades
-
There are three major wall systems have been applied to building: Curtain wall, Stone panel, Composite exterior wall. Metal composite wall secured to a sub-framing system, fiberglass thermal spacer with Z furring, 3” thick mineral wool insulation on air barrier, gypsum sheathing and cold formed metal framing. Metal panel to have a three-coat custom PVF finish. Curtain wall has two types: 2sided or 4 sided structurally glazed system with a thermally improved and 3 coat PVF finished, aluminum curtain wall framing system will be utilized. A high performance insulating low-e glass will be used. An 8” deep shadow box with metal back panel and integrated insulation will be utilized between floors.
-
Limestone panel are used for exterior wall and on the roof with a solar fin system on top to achieve maximum indirect natural skylight. A balcony is located outside of dean’s office on top pf third floor with a green garden.
-
All wall details are shown in the graph.

Roofing
-
The roofing material have a single ply membrane thermoplastic system on rigid insulation with ¼” per foot slope (with tapered insulation provided as necessary to accomplish required slope). The system includes a vapor retarder. A minimum “U” value of 0.05 is provided with the value modified to meet LEED energy requirements.

Sustainability Features
Included in this section should be a description and photos as appropriate of the major active and passive sustainability features of the building or site. Roof top gardens, green roofs (remember they have Roofing underneath…see previous section), solar shades, natural ventilations etc.
Although the project did not go for LEED certification, it was followed LEED process and achieved credits on sustainable sites, water use reduction, optimize energy performance, thermal comfort design, and regional priority credits. The project also required for compliance with LEED NC Version 2009 EA prerequisite 1 – Fundamental Commissioning of the building energy systems and achieved innovation in design on maximize open space.
Part II
Construction
The School of business is a design bid build project that consists of 128,324 SF, the Christman/Brinker is the General contractor and construction manager for the project. The estimate is based upon the guaranteed maximum price (GMP) complete by the general contractor is $48,276,494, as reconciled with WSU and SmithGroup. The duration of the project is 641 days, from 11/13/2015 to 4/27/2018.
Electrical
​
The primary electrical service provides 13,200 volts, 3-phase, 3-wire, delta-connected, 60-hertz and provide by the local electric utility company (DTE Energy). A 208Y/120 volt, 3-phase, 4-wire single-ended secondary unit substation is provided. The substation receives one 15 kV feeder from the utility. The primary feeder will terminate in a 15 kV rated load interrupter fusible switch, forming a radial distribution system. A metering cubicle per DTE Energy standards are provided. The transformer is 1000/1150/1500 kVA (AA/AA/FA), 13,200-208Y/120 volt, 3-phase, 4-wire, 60-hertz with copper windings.
Lighting
​
lighting design is to support the function of the building as a learning center and reinforcing connection between urban activity and the student activity within. The active internal environment generates an internal glow to unify the building, as seen from the exterior and creates a beacon to signal the beginning of the district development.
​
Building contains both daylighting system and exterior/interior lighting system. The building is covered by curtain wall system that provides daylighting. Both exterior/interior lighting fixtures use LED lights to meet the current university standard, the exterior lights are controlled by the campus control system, Lighting will meet current code and campus lighting requirements.
Indirect/Direct lighting at the ceiling and vertical surfaces in building perimeters spaces will create a uniform connection of the interior environment as a seen from the street level on Woodward and Temple. Bi-directional lighting control of indirect/direct LED pendant fixtures will be used after hours at building perimeters spaces to maintain an indirect uniform lighting character when functional lighting is not required.
Mechanical
​
A water source heat pump system is used to condition the building. The system consist of boilers, evaporative cooler, a dedicated outside air units and numerous water source heat pump units which will be located in or near the zone they serve. The Cooling tower is located on the roof to condition the water loop, Two water cooled condensing unit, two boilers and two dedicated outside air units are all located in the mechanical room. The water source heat pump in each zone provide both heating and cooling, cooling tower runs during summer to maintain the water loop condition, and boiler runs during winter to maintain the water loop condition as well as supply the unit heaters in the common area to provide heating during the winter.
Structural
The State University School of Business is a steel structure building.the steel structure consists a composite slab floor and a roof system. The composite slab floor has typical of 3 ¼” concrete slab on 2” 18 GA metal deck, and the roof is 18 GA 0-1 ½ “ metal deck. Steel column has typical bay spans 31’-6”. Foundation has 1’ 4” basement wall with combined footing / square footing. The moment connection for beam to column and steel braced frame are used to resisting lateral loads.
Additional Engineering and Engineering Support Systems
Fire Protection
Water supply for the fire protection system will come from a dedicated water service. A reduced-pressure zone backflow preventer will be provided at the inlet to the fire pump. The electric motor driven fire pump and associated equipment will be located in the Fire Pump Room which will have fire department access. Fire pump shall be on emergency power system. Standpipes shall be Class I manual type and will require fire department pumper truck to deliver necessary water pressure. Standpipes shall have 2 ½” hose connections and will be located at the main floor landing in each of the three exit stairs. A fire pump test header will be provided.
A sprinkler system will be provided throughout the building. Service areas, storage spaces, electrical and mechanical equipment rooms will be designed for ordinary hazard occupancy. Office, instructional areas, lobbies, and corridors will be designed for light hazard occupancy.
Fire protection piping shall Schedule 40 black steel with screwed (small diameter) or mechanical (large diameter) fittings.
Transportation
​
Three Staircases is in charge of the whole building. One is located in west side of area A, another is located in east side of area B, and there’s one in the middle which considered as central staircase along with two elevators placed next to it, which should get most of the traffic. The two staircases on each side are fire rated and can be used for escape.
Telecommunications
​
The building separate as Area A and B for each floor, the intermediate distribution frame (IDF) room are placed on each area on each floor, Main Distribution Frame (MFD) is placed basement of the building next to electrical room. Each IDF connects to the MDF.
