1. Week 7 Utility Data Analysis

2. Essential Elements Identify sources for obtaining utility data: paper form, electronically or from the internet Review utility billing methods and data including peak periods and different rate structures Entering utility data into an audit spreadsheet Graph and interpret graphical energy data Review benchmarking data and compare with standardized Hawaii data.

3. LEVEL II ANALYSIS – ENERGY SURVEY AND ANALYSIS -DETAILS 2. Potential Owner Interface and Information (cont.) Operators and Technicians - Status of current equipment, validation of operational controls, existing problems areas, actual maintenance level of implementation, and modification not shown on drawings

4. LEVEL II ANALYSIS – ENERGY SURVEY AND ANALYSIS -DETAILS 3. Existing Building On-Site Survey Information, validate drawings and other documentation Envelope components (Wall Roof, Floor, Windows, Doors, Skylights, etc.) HVAC Systems components and control strategies and setpoints Lighting fixture types, quantities and controls Equipment schedules, space and occupancy information

5. LEVEL II ANALYSIS – ENERGY SURVEY AND ANALYSIS -DETAILS 4. Breakdown of energy use within building Provide estimate based on Commercial Buildings Energy Consumption Survey data from the U.S. Energy Information Administration Conduct preliminary energy analysis with energy simulation software (i.e METASYS, other Johnson Controls products available).

6. LEVEL II ANALYSIS – ENERGY SURVEY AND ANALYSIS -DETAILS 5. Identify recommended changes to operation and maintenance activities 6. Provide energy savings and cost analysis (i.e. simple payback) of practical measures that meet owners constraints and capital improvement criteria Building envelope feature (i.e. tinting or insulated windows, skylights)

7. LEVEL II ANALYSIS – ENERGY SURVEY AND ANALYSIS -DETAILS 6. Provide energy savings and cost analysis (cont.) HVAC retrofits involving complete replacement of existing systems including higher efficiency equipment, VFD for fans and pumps, improved building automation controls Lighting retrofit replacing MV or HID High bay fixtures with T5 Reflective High bay Fixtures or LED lamps for more efficient lamp/fixture systems. Include utility rebates in cost analysis

8. LEVEL II ANALYSIS – ENERGY SURVEY AND ANALYSIS -DETAILS 7. Provide a list of capital intensive improvement that require further data and analysis. Building envelope feature (i.e. better wall or roof insulation) HVAC retrofits involving complete replacement of existing systems and significant upgrades to building automation controls).

9. LEVEL II ANALYSIS – ENERGY SURVEY AND ANALYSIS -DETAILS 7. Provide a list of capital intensive improvement that require further data and analysis (cont.) Lighting retrofit requiring significant investment such as LED light sources for high bay and light poles. Alternative energy generation systems like geothermal, solar PV, solar hot water, and wind energy.

10. LEVEL II ANALYSIS – ENERGY SURVEY AND ANALYSIS - REPORT 1. Provide summary of energy use and cost associated with each major component. Specify Computer software analysis utilized. Compare actual total utility usage and calculated energy estimates. 2. Provide description of building including floor plans, and inventories of major equipment (place details in Appendices)

11. LEVEL II ANALYSIS – ENERGY SURVEY AND ANALYSIS - REPORT 3. List measure that are impractical or not applicable for the facility 4. Provide discussion of recommended energy conservation measures Existing situation now wasting energy Measures impact on health, safety and comfort Required repairs of existing equipment Impact on occupants, O&M procedures and staff Useful life of equipment

12. LEVEL II ANALYSIS – ENERGY SURVEY AND ANALYSIS - REPORT 5. Provide Summary Table with name of energy conservation measure, estimated annual energy savings, estimated installation cost, and simple payback period. Provide project summary for implementation of all recommendations measures. 6. Recommend Measurement and Verification methods to validate performance of projects. 7. Discuss potential capital intensive measures requiring a Level III analysis.
