2.0 BUILDING DESCRIPTION

This section provides a description of the building, lighting system, HVAC and domestic hot water systems. It also documents any of the environmental or system operational requirements, including the intended sequence of operation.

The Phillip P. Burton Federal building is located at 450 Golden Gate Ave. in San Francisco, California.

The facility consists of a 20 story building with 1,400,000 sq. ft. and was constructed in 1962. The building houses many important federal agencies including: The FBI, US Attorney, IRS, Federal Court Judges, US

Marshals. Ancillary spaces include corridors, conference rooms lobbies, break rooms, fitness center, locker rooms, and restrooms.

2.1 OVERVIEW AND OPERATION

The Phillip P. Burton Federal building is generally occupied from 6:00 AM to 6:00 PM Monday through

Friday with limited occupancy on the weekends. There are areas of the building that have 24/7 occupancy, but main building HVAC systems are not required to run during nights and weekends. There are approximately fifteen small computer rooms (< 5 tons cooling requirement) and one medium sized computer room (20 tons cooling requirement) that require 24/7 cooling; these computer rooms are all served by dedicated Computer Room Air Conditioning (CRAC) units.

2.2 LIGHTING SYSTEMS

Interior lighting systems consist mostly of T-8 fixtures with electronic ballasts and recessed canned fixtures with compact fluorescent lamps. The majority of the lighting is controlled by wall switches. Open space lighting on floors SB-7 was recently upgraded to suspended direct/indirect fixtures and a proposal has been submitted to upgrade the remaining floors in kind.

The lighting system in the building office areas are controlled by local area switches. All stairways and most of the bathrooms have occupancy sensors to control lighting. The exterior lighting is mostly metal halide and controlled by timers. The majority of the exit signs are the ‘radioactive’ type and consume no energy.

2.3 HVAC, CONTROLS AND DOMESTIC WATER SYSTEMS

This section provides summary description of the building’s HVAC and control system.

Each of the three chillers has its own dedicated constant volume condenser water pump. The CW pumps draw water from the tower return piping and discharge it into the pump discharge piping. The circuit continues through the condensing (heat rejection) side of the chiller, to the CW supply piping, and to the enabled cooling towers. Once the water passes over the cooling tower fill and rejects the heat from the chillers, the condenser water collects in the sump at the bottom of the tower and drains into the tower return piping, which completes the cycle. Water lost through evaporation at the cooling tower is made-up through an auto-fill connection to water supply. This water supply undergoes chemical treatment to minimize corrosion and scaling in the tower.

Table 2.3.4 Cooling Tower Summary

There are three Universal natural gas-fired modulating capacity boilers rated at 12.5 MBTU input and 10

MBTU output. There are three 20 HP hot water pumps with VFDs serving a primary only variable flow hot water distribution system. There is a common header between the boilers and the pumps are controlled to maintain a DP, set point and to maintain minimum flow through the boilers based on HW valve position.

Table 2.5.1 below is a summary of the boilers and table 2.5.2 is a summary of the boiler pumps.
