  2. Fort Sam Houston Energy Program

  3. Fort Sam Houston Energy Management Team CEAN (ENV Office) provides oversight of energy program Energy Manager (Mr. Jerry McCall) 210-221-4203 Resource Efficiency Manager (Mr. Frank Thomas) 210-221-4147 Utility Sales Officer ( Mr. John Gonzales) 210-295-4770 Utility Clerk (contractor) Utility Clerk (GS-09/11, Vacant)

  4. Fort Sam Houston Project Highlights • FY11 NRG Lighting Retrofit Building 4055 ($200K) • 90,654 SF Logistics Facility • One for one lighting fixture replacement • Metal halide high bay with T5 HO fluorescent • T 12 fluorescent with high performance T8 fluorescent • Other miscellaneous fixture replacement • Install occupancy sensors, reducing burn time • Being advertized to contractors • Bid opening 8 July • Award 29 July • Estimated annual savings $19,672 and 959 MBTU

  5. Fort Sam Houston Project Highlights • FY12 NRG Modernize Central Energy Plant Bldg 1377 ($1.6M) • Current central chiller plant acts as 2 separate loops • Reconfigure to allow chillers to operate as true central plant • Add 2 chilled water pump/motors • Install new primary pump/motors • Install secondary variable flow pumps with VFDs • Add one cooling tower • Upgrade main switch gear • Significantly reduce operating cost & improve backup cooling • Estimated annual savings $205,000 and 9003 MBTU

  6. FSH 2011 Investment Grade Energy Audit • Energy Audit (Energy Engineering Analysis Program) • An Energy Optimization Assessment was conducted at Fort Sam Houston in 2011 • Energy Engineering Analysis Program (EEAP) initiative • Purpose to assess & identify energy inefficiencies in 20 representative buildings, 1.3 million SF • Included HVAC, controls, lighting, water use and appliances • Renewable energy resources were also analyzed

  7. FSH 2011 Investment Grade Energy Audit • Energy Audits • Results identified 177 different energy conservation measures (ECMs) • Potential Fort Sam Houston's annual energy savings up to 11.4 MWH/yr electric and 12,644 MBtu/yr thermal savings. • Total energy savings can be $1,024,981 per year • Total investment of $7,992,152 is required to implement the ECMs • Simple payback of 7.8 years • Result in a 5.4% reduction of installation's 2010 energy intensity

  8. CPS Energy Demand Response Program • FSH’S CPS Energy Demand Response Pilot Project Buildings 2840 and 2841 • CPS Energy’s Demand Response program is a voluntary load curtailment program • DR Program for commercial and industrial customers. • DR program designed to reduce CPS Energy’s peak load growth • Incentivizing customers to shed electric loads on peak summer days. • Credit per Curtailed kW = $46.00/kWh

  9. CPS Energy Demand Response Program • Demand Response Program • Demand Response season begins June 1 and ends September 30 • Demand Response events typically occur on weekdays between 3 p.m. and 6:30 p.m. • Customers must be available to curtail between 1 p.m. and 7 p.m. • Receive a two-hour advanced notification of when to initiate and end their curtailment. • Johnson Controls agreed to partner with FSH assuming responsibility for load shedding Bldg 2840/41 • Thus far, curtailment successful on each request • Plan is to expand to multiple buildings next summer • Program will save energy and save/earn $$$

  10. Fort Sam Houston Energy Management Control System Project • UMCS Phase V Utility Monitoring Control System • Contractors will survey existing HVAC controls systems • Provide design for new HVAC controls systems, where required • Create UMCS front end screens where screens do not exist • Modify existing screens that are not functional • Perform point checks and verification • Replace hardware that is not functional • Re-commission affected systems

  11. FSH Controls Project • UMCS Phase V Utility Monitoring Control System (continued) • Where specified, the contractor shall replace existing field device controllers & field devices (thermostats, damper actuators, valve actuators etc) • Run new fiber optic cabling, install new managed switch • Contractor shall create new front end screens using Rockwell Automation RSView32.

  12. Fort Sam HoustonEnergy team Evolving The FSH Energy Team is growing to meet the increasing challenges of conserving our natural resources and meeting the conservation mandates. The team will focus on: • Creating a culture of energy change (conservation) • Implementing viable energy conservation projects • Managing its facilities effectively and efficiently
