HomeMy WebLinkAbout4/4/2001 - STAFF REPORTS (14) DATE: April 4, 2001 TO: City Council FROM: Interim Director of Aviation AIRPORT ENERGY USAGE MODIFICATIONS RECOMMENDATION: It is recommended that the City Council accept the proposal for modifications to the Airport central plant and energy control and monitoring system from Siemens Building Technologies, Inc. and authorize the associated work in an amount not to exceed $114,266.00; and, amend the Fiscal Year 2000-2001 budget to appropriate an additional $84,266.00 from Airport reserves to cover part of the installation cost. SUMMARY: During the peak summer months, the ability of the Municipal Cogeneration (COGEN) plant to provide adequate cooling to City Hall, the Police Department, Fire Station#2, the Corporate Yard and the Airport is hampered by the high temperatures. This proposal(see attached)would modify the Airport's central plant such that chilled water could be returned to the COGEN plant for thermal storage, which will allow the plant to provide adequate cooling to the various City facilities. BACKGROUND: The Municipal Cogeneration (COGEN) plant provides electrical power, and hot and chilled water to City Hall, the Police Department, Fire Station #2, the Corporate Yard and the Airport. The Airport central plant, which was installed during Phase IIA of the terminal expansion, includes two (2) large chillers that are capable of providing chilled water for air conditioning within the terminal facility. All of the Heating, Ventilation and Air Conditioning (HVAC)equipment for the Airport is controlled by an operating system supplied by Siemens Building Technologies, Inc..The control system includes software and associated control wiring and devices for controlling HVAC equipment(chillers, air handlers, cooling towers, etc.) throughout the terminal facility. While the equipment for providing chilled water exists at the Airport, the piping and valves necessary to return chilled water to the COGEN plant for thermal storage does not exist. This proposal would make the necessary piping, valve and control system modifications to allow the Airport central plant to return chilled water to the COGEN plant for thermal storage, thereby improving the efficiency of the COGEN plant. In many mechanical applications, the capability of the control system determines the layout of the necessary piping. As the control system software and associated equipment is proprietary to Siemens Building Technologies, Inc., Airport and Facilities staff have worked with Siemens Building Technologies, Inc. in developing the proposed modifications. Siemens Building Technologies, Inc. has committed to have the modifications completed no later than June 6, 2001. Siemens Building Technologies, Inc. was competitively selected to provide HVAC controls during Phase I of the terminal expansion in 1990. /ah April 4, 2001 Page 2 All of this work except the engineering will be performed by Siemens Building Technologies, Inc. personnel. Engineering services will be provided by an outside firm as stated in the attached proposal. With the on-going energy situation and its associated budget impacts, staff requested Siemens Building Technologies, Inc. to provide proposals for modifications to the Airport central plant and HVAC control system such that it could perform the following functions: 1. Modification of the Airport central plant piping, valves and HVAC control system software to allow the airport chillers to provide additional thermal storage of chilled water to the COGEN plant. 2. Modification of the HVAC control system software and installation of associated equipment to provide "real-time" consumption of hot water (BTU) monitoring, which is used for heating of the terminal facility. 3. Modification of the HVAC control system software and installation of associated equipment to provide "real-time" consumption of electrical energy (power monitoring) utilized by the airport. The total cost for this proposal of $114,266.00 includes a 10% contingency of $10,388.00 to allow for any unforseen circumstances. Funds in the amount of $30,000.00 are available in account no. 520-5641-48700 "Cogen Special Parts & Repairs". A budget amendment for the appropriation of the remaining amount of $84,266.00 from Airport Retained Earnings (The Landside Reserve) to account no. 415-60-6400-50015 "Specialized Equipment" is requested. The Airport Commission will consider this item at it's regularly scheduled meeting of April 4, 2001. A Resolution authorizing the acceptance of this proposal and a second Resolution for a budget amendment is attached for City Council consideration. ALLEN F SMOOT, A.A.E.

Per your fax, we made the following changes: All references to "Construction" and "Contractor" have been replaced with "Installation" and Installer". • We stipulated three (3)job site/owner visits by the Engineer and as-built drawings. • We combined the hot water BTU and electrical monitoring into the proposal. We also combined the estimates. This resulted in cost savings of$1,060.00. A project time-line section was added.

Tahquitz Canyon Way Palm Springs, CA 92263 Re: Airport Terminal Chilled Water Plant Modifications + Additive Alternate(s) Dear Craig, Siemens Building Technologies, Inc, is pleased to provide this proposal for the engineering design services, mechanical work, control systems work and project management for operational modifications to the Airport Terminal chilled water plant. Our proposal is based on meetings with Airport and City facilities personnel, review of as-built drawings and sequences of operation, and job walks to observe existing conditions. The design will be limited to the modification of the existing Airport chilled water central plant piping, valves and controls and will utilize the existing chilled water Pumps- Present Situation The Airport Terminal chilled water plant provides chilled water to the air handling units and fan coil units serving cooling loads for the old and new tennhial buildings- The chilled water plant is comprised of two centrifugal chillers, two cooling towers, two condenser water pumps, two primary chilled water pumps and two secondary chilled water pumps. In addition to the cooling capacity provided by the local chillers, the chilled water plant receives chilled water from a City-owned thermal energy storage equipped co-generation plant via campus wide chilled water loop. The campus wide chilled water loop serves several City-owned facilities in addition to the Airport Terminal chilled water plant. During conditions of extended high ambient temperatures and cooling load, the co- generation plant and its thermal energy storage system lack the capacity to handle the total load of the campus wide chilled water loop. The result is the chilled water delivery temperature gains approximately two degrees F. per 24 hour period. After several days, chillers in the City-owned facilities, including the Airport, must be started to handle the load- Since these chillers operate during electrical on-peak periods, the utility cost to the City of Palm Springs is excessive- The present Airport chilled water central plant replaced a smaller single chiller central plant when the new terminal was designed and constructed. The original central plant was capable of reducing the campus wide chilled water loop by sending excess chilled water capacity into the campus wide chilled water loop's chilled water return piping.
