6 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

7 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/ 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.

12 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) New Construction is being designed to Collaborative for High Performance Schools (CHPS) standards.
