Background

Opened in 1987, the Southside Service Center provides facilities for portions of the City’s Equipment Services, Code Compliance, and Transportation & Public Works departments. The multi-building campus totals roughly 63,000 sq. ft., the largest part a single-story, wood-framed building of 42,000 sq. ft. The Southside Service Center project is part of a larger $10.9M phase of an energy savings performance contract (ESPC), and is based on an energy assessment conducted by the City’s competitively-selected energy service company (ESCo.)

Solutions

Project solutions identified at the Southside Service Center may be considered common opportunities, replicable across many building types. Cost-effective solutions selected for implementation include lighting, air-conditioning, control, and water system improvements. Fort Worth looks for solutions that generate annual cost-avoidance sufficient to pay for the turn-key cost of implementation, including development, financing, and performance verification. For implementation, solutions must indicate simple paybacks within their useful lives.

Other Benefits

Fort Worth receives many benefits associated with implementing facility improvement measures. Primary among these is improved environmental air quality achieved through reductions of electricity power plant pollutants due to the reductions in electricity consumption.

Background

The Texas Emissions Reduction Plan (TERP) was established by the 77th Texas Legislature in 2001, through enactment of Senate Bill 5. The TERP includes voluntary financial incentive and other programming to assist political subdivisions in improving the air quality across Texas. Under the TERP, affected entities such as the City are asked to implement energy-efficiency measures and to establish a goal to reduce their electricity consumption. The State Energy Conservation Office (SECO) of Texas assists political subdivisions in meeting TERP goals by providing various forms of assistance. In 2001, the City consulted SECO about best-practice to achieve the stated TERP goal; ESPCs were considered one such way. The City chose to develop an ESPC through competitive, best-value selection of an ESCo. After selection, the City’s first phase of its amendable ESPC was authorized in 2003. Since substantial completion of ESPC Phase 1 in 2004, the City has fully implemented seven other phases from development through construction and performance. The current ESPC Phase 7 was authorized in 2013, with substantial completion due in 2014, and its performance period extending through 2026. While over 100-City facilities were included in previous ESPC phases, the Southside Service Center had not been, due mostly to its smaller size and the types of departments served. This site was selected as part of ESPC Phase 7 because it proved to have cost-effective opportunities based on the ESCo’s assessment.

Solutions

The Southside Service Center project includes the following facility improvement measures, which are followed by a table of their estimated impacts:

  • Lighting Improvements – interior T8, T5, and compact fluorescent lamps, electronic ballasts, reflectors, occupancy-based controls, LED exit sign and wall-pack fixtures, and exterior LED fixtures with automatic-controls
  • HVAC & DDC Upgrades – variable-air-volume terminal units, water control valves, variable-frequency motor drives, and direct-digital controls
  • Retro-Commissioning – control point verification, functional performance testing and balancing of building air-conditioning systems
  • Water Conservation – low-flow toilets, flushometers, and faucet aerators

Other Benefits

Additional benefits to the community include better fiscal management of City operating and capital budgets, and best-practice upgrades to facility infrastructure necessary due to systems at or near the end of their useful life using proven, state of the art systems, equipment, and controls.
