There is also a curtain wall system with energy efficient glazing wrapping around the corner of the main entrance at the Southeast Entry.
Roofing
The typical roofing for the majority of the building was thermoplastic polyolefin (TPO) adhered on concrete of metal stud. There is a green roof lining the edge where there is a vegetated roof assembly along with a vegetation free area.

In order for the construction of this building to take place, demolition and excavation need to occur but will not be included in the scope of this project. The Entertainment and Sports Arena is divided into 3 sectors for construction purposes starting with Sector A being the practice facility at the West end of the building, the West half of the arena being Sector B, and the East half of the arena being Sector C. The building commissioning and turnover phase is intended to be complete by August 27, 2018.

This main distribution is located in room 136. The main electrical source for the building is a 4000A, 480Y/277V, 3 phase, 4 wire system. The main switchboard, MSG-1, is fed from two pad-mounted utility transformers to two 4000 Amp main breakers. The feeders are encased in concrete. Power is then distributed to the various panels on the different levels of the Entertainment and Sports Arena. An emergency standby generator is equipped with a built in main circuit breaker at the second level. The general distribution switchboard for the emergency switch gear is a 1200A, 480Y/277V, 3 phase, 4 wire system.

Lighting fixtures used in the practice court are 6" recessed low canopy down lights. Fixtures in the practice court are 19.1W LED fixtures with required voltage of 277V. There is a low voltage switch at every entry point to the practice court. There are ceiling mounted low voltage occupancy sensors that provide a more energy efficient lighting system. In the main court there are 4" recessed wall wash fixtures that are 13.9W LED and also have a required voltage of 277V. In addition there are 6" recessed high canopy down lights. These fixtures are 40W LED and require a voltage of 277V. All bathrooms and concession stands on the concourse level have occupancy sensors. All of the office spaces, lounge rooms, exercise rooms, locker rooms and hallways on the practice facility side of the arena have either occupancy or vacancy sensors. As the Entertainment and Sports Arena is aiming to achieve LEED Silver certification, lighting in all work stations in the administrative spaces of the building will be provided with plug-in task lighting with individual controls.

One VAV unit with medium pressure classification will serve for the wizards operations and one will serve for the event operations. Two single zone VAV units with low pressure classification will serve the arena bowl. There are four roof top units with an enthalpy serving the building as well. All units are a CV DOAS system with medium pressure classification.
