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…
Energy Performance Contract/ ESCO
Other Projects in Contract:
Window upgrades
Tridium Integration with legacy EMS EMS installs and replacements Automated Meter Reading Boiler Tune-ups
Pneumatic Tune ups Boiler Conversions (electric to gas) Trailer Controls - Bard controllers Chiller monitoring (Carrier)
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.
