EXECUTIVE SUMMARY

This technical report examines the existing electrical conditions for The Salt Lake City Public Library in Salt Lake City, UT. A campus system provides power to two primary 7.2 kV feeds for a 480/277V, 3Ph, 4W electrical system. A single‐line diagram describes the full extent of the existing electrical distribution systems.  

This report also provides a summary of the total building lighting, mechanical, plumbing, and architectural equipment loads. Several methods depending on the project phase show that the sizing of the main distribution equipment does not accurately compare to the existing equipment. The disparity with the existing equipment is likely a combination of various assumptions and the difference in additional considerations for future expansion. 

Additionally, the report includes a narrative describing the various communication systems in the Library including security, fire alarm and detection, public address, telecommunication, and audio visual. Supporting material for this report is provided in the attached appendix.

Single‐line Diagram Drawing List 

The following is a list of drawing numbers and titles from the existing electrical drawings that were used to prepare the single‐line diagram:  E60.01 – Normal Power E60.02 – Normal Power E60.03 – Emergency Power E60.04 – Grounding Diagram 

 

Single‐Line Diagram Drawing  

The single‐line diagram drawings and feeder schedule can be found in Appendix A, which shows the service entrance and key elements, layout and sizes of the distribution system, and the related components from the power source to the distribution system.  

 

Summary Description of Distribution System  

The Salt Lake City Library is powered by existing lines from the Salt Lake City’s main utility building sub‐station on the southeast corner of the site. Two primary 7.2 kV feeds into double‐ended 3000A, 480/277V, 3Ph, 4W and ground switchgear provide the main service to the library through the main service switchboard SWB‐1/2. The connected buildings each have a designated normal and emergency power supply. A series of 480V risers offer secondary power distribution while transformers on each floor provide 120V for receptacles, incandescent lighting, and heaters.  

 

Utility Company Information  

The utility company name, address, website, rates, and load data that provides power to the campus system is provided below. A summary of the Electric Utility Load Data for the previous 12 months was unavailable and not included in this report.  Rocky Mountain Power, a division of PacificCorp 201 South Main St., Suite 2300 Salt Lake City, UT 84111 http://www.pacificorp.com

Over‐current Devices  The main over‐current device in the main service entrance switchboards is a metal enclosed fuse switch, 3‐pole, 7.5 kV – 15kV, 600AS/150AF, 40K AIC. The fuse switches are provided with Class R rejection fuse clip kits.   The branch over‐current device in the main service entrance switchboards are a 300A, 3‐pole molded case systems breaker set at 2500A solid state trip mechanism. The breakers are UL listed for application at 100% of the continuous ampere rating. Ground fault sensing and relaying equipment is also provided. The solid‐state ground‐fault relay requires no external source of electrical power and draws energy from output of current sensor to operate the ground fault protection system (GFP). The breaker protects the normal power bus rated at 65,000 AIC and the emergency switchboard rated at 50,000 AIC.  A molded case circuit breaker is the over‐current protection device in a typical lighting and appliance panelboard, as well as a distribution panelboard.  

 

Transformers  There are two main types of transformers used to step‐down the voltage in the building. A dry type 1500 kVA transformer steps down the service voltage from 7.2 kV to 480/277, 3Ph, 4W at each of the incoming service feeds. This voltage is stepped down again to 120/208V, 3Ph, 4W with a dry type transformer. See transformer schedule below (Table C).

Special Equipment 

A transient voltage surge suppressor (TVSS) is located on Level 2 for the normal power and protects the main distribution bus loads. The TVSS is used to protect the system from a temporary surplus of voltage and/or current in a disrupted electrical circuit by diverting or limiting surge current. It is AC three phase and suppresses surges, spikes, and transients.  

 

Lighting Loads 

Over 8,500 feet of linear T5HO fixtures throughout the general library of the triangle building and office areas of the bar building provide indirect and diffuse lighting while highlighting the architectural barrel vaulted ceilings. In addition to the 87 different types of light fixtures and six types of tracks, several custom luminaires were designed specific for the Library. The auditorium includes downlights, track lighting, uplights, and linear fluorescent strips. The exterior lighting is comprised mostly of step lights, post‐tops, and in‐ground fixtures to highlight the water features.

ASHRAE/IESNA 90.1 requires automatic shutoff for this building (larger than 5000 SF) and must be controlled by an automatic control device to shut off building lighting in all spaces. The control device must function on a scheduled time‐of‐day operated control device, an occupant sensor, or a signal from another control or alarm system.   See luminaire schedule (Table D). For HID ballast cutsheets, see Appendix B.

contributed to the service equipment size for the Actual Loading Method being much smaller than the existing service equipment size. In addition, the actual service conditions include significant space for future expansion. 

Environmental Stewardship Design  

Sustainable electrical design was not a top priority during the design of the building. However, the primary source of light throughout various areas of the building is daylight. This saves a significant amount of energy that would otherwise be used by electric lighting, particularly in the public Urban Room. An occupancy sensor and photocell sensor controls the lighting only on the ground level based on sufficient daylight and the presence of occupants.  The electric lighting in the main library space of the Triangle and the offices in the Bar Building utilizes more efficient and longer lasting T5HO lamps with higher light output than other fluorescent alternatives. Given that the library was designed in 1999, these lamps were chosen during a time where T5HO lamps were relatively new technologies. The electrical systems design is lacking in energy efficient transformers, on site power generation, and special electrical materials/local sources. 

 

Design Issues  

Reliability issues were of main concern for the design of the building. A transient voltage surge suppressor located on both sides of the main service switchboard, helping to regulate the voltage and protect against voltage spikes.

COMMUNICATION SYSTEMS    Summary Description:    

The communication systems throughout the building include dimming control devices, security, fire alarm and detection, a public address system, telecommunication, and audio visual systems. The distribution panels and control is located in the communications rooms on the ground level of the building.  

 Security:  Motion detectors, overhead door switches, door contacts, and card readers are supplied by the access control/security panel. A security monitoring room on Level ‐1 at Rooms BG and T1 provides access control and security badging/operators station.  Security cameras are located throughout the building. Cameras monitoring the exterior are installed in the northeast loading dock and southeast parking area of the Level ‐2 parking area, as well as in the Children’s Garden and public plaza of Level ‐1. Additional security cameras are located within the main library building, the public Urban Room, parking garages, a main bridge connecting the Triangle Building to the Bar Building, and on the rooftop garden. Closed‐circuit television (CCTV) utilizes a series of monitors in at the circulation desks for surveillance.   The library security also interfaces with a radio frequency identification (RFID) scanner which allows safekeeping of the books between the main library building and other public parts of the building.  

 Fire Alarm and Detection:  Fire alarm manual stations, horns and signal strobes are located through the entirety of the building.   Public Address:   A speaker infrastructure is located throughout the office space in the Bar Building, which connect to the communications room on the ground floor. Public address is also extensive in the Triangle main library, Urban Room, and Children’s Library, which also connect to the communications room on the ground floor. The power supply for the microphone is connected to a DSP, which is then amplified and stepped down with a transformer before entering the speakers.

[27] 

 Telecommunication:  Data via fiber optics and voice (UTP) enter the building from Telco through a street manhole and travels through the service electrical room to the main communications room. A riser field and station field for both data and voice in the communications closet feed workstations for areas without a raised floor system. The station cabling runs from the main communications room directly to the typical workstation or first through a communications closet for areas that have raised floor access. The building is equipped with wired and wireless local area network (LAN).  

  Audio Visual:  

The audio visual features of the library include a multiuse auditorium with multimedia presentation capabilities for video, slide, computer display, and cameras for long‐distance learning. The multipurpose room is equipped with sound reinforcement, projection capabilities, and tie lines. Video projection and the capability for computer display are also featured in the computer training rooms. Another training room is equipped with video conferencing, while the library boardroom has rear projection video and computer display and audio and video conferencing. Satellite TV is also distributed throughout the building.
