Lighting
Light Replacement
Building Maintenance replaces building standard lamps at no charge to Tenant. For service, please submit a tenant request via the building portal or call the Building Management Office.
Zones
Advanced Automated Systems is the lighting control system for Park Tower. There are up to ten zones per floor. The average estimated maintained lighting level at desktop is a 50-foot candle, with the additional capability to increase to 70-foot candles.
Electrical Distribution
Power enters the Building from a SMUD transformer vault via two 4000 amp, 480/277 volt, 3 phase, 4 wire switchboards. Power to each floor is fed from two electrical closets on each floor. Two branch circuit termination points are provided for each floor so that circuit lengths are limited to less than 100 feet and increased wire sizes can be avoided. Each electrical closet has one 100 amp lighting panel (277/400 volt), as well as two 120/208-volt branch circuit convenience load panels (42 poles each). Step-down transformers are located on every second or third floor and are 150 KVA in size. All building standard breakers are 20 AMP. Park Tower has an emergency generator serving stairwells and elevator lobby, pressurization fans, emergency lighting, fire alarm system, smoke detectors, security system and one elevator in each of the high-rise and low- rise elevator banks, as well as the freight elevator. Park Tower provides a total of 8 watts per square foot: 2 watts for lighting, 3 watts for equipment, and 3 watts for future tenant demand. This is independent of the 7 watts per square foot operating Building mechanical equipment.
