Utility Budget FY08

 Electricity Budget $28.7 million  Gas/oil $11.4 million $40.1 million - total electric and gas budget

Energy Management Section

 Coordinator  2 Energy Management System Specialist  1 Shop Supervisor  3 EMS Technicians  2 Mechanical/Controls Engineers  1 Inspector 10 positions total

Control Systems

Andover 102 Automated Logic 19 American Automatrix 16 Carrier 12 Delta 4 Honeywell 1 Invensys/BarberColmen/Seibe 33 Novar 1 Powers 7 Siemens 1 Trane 13 Tridium 32 (most integrated with other systems) Proliphix web thermostats -307 in modulars +/- 242 systems

Controls Replacements

23 DDC controls projects are in some stage of construction from planning/design to final punch out/warranty.

Replacement done through: – Design and Construction new or renovated buildings – Infrastructure Engineering –Replacement – Energy Management – upgrades/replacements/modifications – ESCO – New or replacements

Energy Performance Contract/ ESCO      106 Buildings 10,453,683 Square Feet $19,313,572 investment $2,470,448 estimated annual savings 7.8 year simple payback Preliminary work/feasibility/RFP began 2001 Construction started 1/2003 - Completion August 2006 Contract is “turn key” design build. FCPS dedicated no full time project manager. Part of coordinator time plus 1-1/2 inspectors.

ESCO provides design.auditing engineers and project management resources. Up to 4 full time PMs at times. Most work occurs and is managed at night.

Energy Performance Contract/ ESCO  T-12 to T-8  MH to T-5 in gyms  Incandescent to compact fluorescent  All new LED exit signs – no conversion kits  Occupancy sensors  No de-lamping or reducing light output!

 Watch product selection carefully…

Other Stuff

Energy Watchdog for bill tracking Energy Management Web Portal EKA automated meter reading upgrade to server US EPA Energy Star Portfolio/ SchoolDude/FSDirect scheduler Modular building web base thermostat upgrade Training program for HVAC and Operating Engineers Reverse auction for gas via Washington Council of Governments COG Migration to “web based” 632 EMS devices with IP address - had one device in 2003.

Migration to graphical/web interfaces - 147 graphical systems – had one in 2003

New stuff in the pipeline….

     New Construction is being designed to Collaborative for High Performance Schools (CHPS) standards. Emphasizes energy use (lighting and HVAC) more than LEED ( NOT doing LEED) Geothermal heat pumps - evaluating now – expect to start using them soon.

PJM Demand response program pilot in 5 schools Switching 2 schools from VEPGA 130 to 132 schedule as pilot.

Formal internal energy audits of schools by engineer with improvement tracking.
