Consultant will provide draft reports electronically via an Adobe Acrobat PDF. Consultant will deliver bound hard copy
<br />final reports (per the contract requirements) and CDs with complete reports on each. All electronic copies of the
<br />report will include all text, deficiency tables, digital photos, and supporting documentation and report appendices. In
<br />lieu of printing reports and meeting minutes, Consultant will use digital distribution for materials.
<br />ENERGY AUDIT AND SOLAR FEASBILITY TECHNICAL APPROACH
<br />The Energy Audit consists of an on-site assessment to verify the current conditions, itemize the energy consuming
<br />equipment (air conditioning, fans, and blowers) as to what was identified during the previous audit; review lighting
<br />systems both exterior and interior; review appliances; and review efficiency of all such equipment. Consultant will
<br />consider structural elements (building envelope) for energy efficiency. Recommendations will be made on
<br />implementing cost-saving ECMs. Consultant will estimate the projected payback period on each energy-saving
<br />recommendation and prioritize accordingly.
<br />Prior to conducting the Energy Audit, Consultant will complete a Historic Energy Consumption Analysis and Energy
<br />Benchmarking, including completing the following tasks for the facility:
<br />• Obtain and review the previous 2 years of utility bills including electricity, and natural gas;
<br />• Establish base year consumption and review base year costs and utility rates; and
<br />• Enter utility data into ENERGY STAR Portfolio Manager energy benchmarking system.
<br />Consultant will collect and analyze the utility data for the properties for the past 24-36 months, and review the prior
<br />property condition assessment or applicable engineering study. Consultant will interview Facility Engineers with
<br />knowledge of the properties, notably building systems and components, in order to provide a general overview of the
<br />facilities and to identify opportunities for energy cost savings.
<br />Following the benchmarking study, Consultant will conduct detailed energy audits of all facilities listed in the RFP. This
<br />includes detailed on-site survey/energy audit and engineering analysis of building systems, building simulations using
<br />in-house developed spreadsheet method, and analysis of savings with estimated installed costs and paybacks.
<br />The energy audit will include, but will not be limited to, the following:
<br />• Building envelope inspection including doors and windows for type of glass, insulation level and shading factor,
<br />weather sealing, walls and roof for insulation, cracks, and missing weather seals to identify energy loss.
<br />• Detailed inventory of all HVAC equipment, boilers, furnaces, air conditioning equipment, chillers, pumps, fans,
<br />motors, lighting, and irrigation systems serving the buildings.
<br />• Energy metering system review and evaluation of potential for sub meters, as applicable.
<br />• Audit of HVAC systems, evaluation of piping for leaks, and insulation upgrades evaluation of chemical treatment of
<br />water, blow -down frequency, and condensation of system performance survey of steam traps heat exchangers and
<br />identification of opportunities for heat recovery.
<br />• Review of current O&M procedures, and recommendations to optimize maintenance.
<br />• Photometric analysis of light levels in all spaces.
<br />• Development of a detailed lighting schedule with opportunities for improvement through replacing T12 light
<br />fixtures with Super T8s/TS, magnetic ballasts with electronic ballasts; and identification of opportunities for de-
<br />lamping through measured lumen levels.
<br />• Recommendations for motion/occupancy sensors for low traffic and sporadic occupancy areas, and photo sensors
<br />for areas with adequate day light; and recommendations for bi-level and tandem ballasts.
<br />• Evaluation of chilled water systems; performance evaluation of chilled and condenser water production, and
<br />cooling load/demand; and calculation of operating kW/ton and identification of opportunities to optimize/improve
<br />performance.
<br />• Survey, record, and evaluation of the EER/SEER of the window and split unit air conditioners serving the buildings
<br />and other areas, to identify opportunities to replace older units with Energy Star alternatives; and identification of
<br />opportunities for centralized systems.
<br />• Evaluation of the efficiency, sizing, and performance of all motors and pumps in the entire facility, and
<br />identification of opportunities forvariable frequency drive (VFD) controls.
<br />• Audit of air handler performance throughout the buildings, air distribution ducting, and potential for VFD control
<br />of supply and return fans in variable air volume (VAV) systems.
<br />• Evaluation of existing (or potential for new installation of) EMSs.
