7. Self-Assessment Target Areas • Utility bill documentation & benchmarking • Identify & log energy consumers (ie: lighting fixtures, air compressors, space heaters, motors etc) • Review: • Building envelope • Lighting • HVAC Systems

8. Energy Self Assessment ObjectiveDetermine current energy consumption levels, identify energy consumers within the operation and establish a benchmark for future energy efficiency improvements.

9. Energy Self Assessment(cont) Process • Define the scope of the assessment • Inform senior management of plan for self assessment • Collect utility bills from the previous 12 months for each building within the scope of the project • Conduct a walk-thru of each building, listing the energy consumers and record building envelope, lighting & HVAC observations

10. Energy Self Assessment(cont) Process • Transcribe observations & enter utility bill data into a spreadsheet • Identify “low-hanging-fruit” opportunities • Present results and recommendations to senior management • Solicit assistance to further evaluate targeted opportunities

11. Building Envelope • Building Envelope Comprised of: • Roof/ceiling assembly • Wall assembly • Floor assembly • Slab edge • Below grade wall • Windows & skylights • Doors • Other components to permit the passage of air, light, vehicles or people • Sometimes referred to as the buildings “shell” or “skin” • Controls the flow of energy between the inside & outside of the building

12. Examples of Recommendations(cont) Building Envelope • Replace missing insulation • Replace wet insulation • Unblock windows to let in passive solar energy • Replace cracked glass in window • Caulk around plumbing pipe, gas pipe & H2O spigot • Repair broken heat pipe • Weather strip around doors • Consider highly reflective ELMS roofing • Place dampers in outside exhaust • Insulate around roll-up doors • Patch hole to outside in wall

13. Building EnvelopeBreach

19. Examples of Recommendations HVAC (up-to 30-35% of energy) • Use set back thermostats • Reduce (or increase) temperature set points • Replace w/energy efficient AC unit • Adjust air vents to equalize tempered air • Use timers & sensors on air fans • Seal leaking ducts • Replace glass in broken window • Reduce HVAC in un-occupied bldg or space • Use operable windows in mild weather • Eliminate space heater & add register • Install ceiling fans to distribute air • Insulate steam pipes • Insulate hot boiler surface

20. Examples of Recommendations Lighting • Change from T12 to T8 fluorescence lamps & electronic ballasts • Install occupancy sensors in restrooms & lunch areas • Delamp • Replace 40w incandescent w/LED’s in exit lights • Incorporate T5 fluorescence fixture as task lighting Alternate Sources & Harvesting • Use scrap wood for alternate fuel boiler • Consider Geothermal heat pump • Capture vented heat to preheat boiler charge • Consider solar hot water heating • Capture & redirect process for space heat

21. Lighting • Incandescent lamp is the least energy-efficient light source with a relatively short life. • 70%-90% of the power consumed is lost as heat.

22. Fluorescent Lighting

23. LightingT12 to T8 Fluorescent

24. LightingT12/T8/T5

25. LightingLED Traffic Lights

26. Examples of Recommendations Boiler & Steam Systems • Reduce Leaks • Adjust air/fuel ratio • Insulate piping • Reuse boiler hot exhaust gas • Recover condensate Compressed Air Systems • Reduce leaks • Reduce pressure • Eliminate inappropriate use • Use outside air • Recover Heat

27. Upgrade to High Efficiency Lighting

28. Energy StarPortfolio Manager • What is it? On-line energy management tool to enable organizations to track & assess energy and water consumption across a portfolio of buildings • Benefits • Enables benchmarking & tracking of energy and water use and costs over time • Enables operators to rate performance vs similar buildings, nationwide • Provides a process for Energy Star building certification

29. Energy StarPortfolio Manager • Features • Tracking of multiple energy & water meters for each building • Customization of meter designations • Benchmark current performance • Track improvement over time • Monitor energy & water costs • Share information within and outside the organization • Compare cost savings within the building portfolio & between projects • Create a statement of energy performance for each building

30. Energy Star Rating Eligible Buildings • Offices • Courthouses • K-12 schools • Residence Halls/Dorms • Hotels • Medical offices • Hospitals • Wastewater treatment plants • Grocery Stores • Retail Stores • Warehouses • Bank/financial inst
