The document discusses strategies for reducing energy costs through green energy solutions. It recommends conducting an energy audit first to understand current energy usage and costs before implementing efficiency upgrades or renewable energy sources. Energy efficiency measures like improved lighting and controls can save significantly on costs. Solar PV is also presented as a key renewable resource that provides distributed generation to reduce grid usage. Overall the presentation focuses on using energy audits and efficiency upgrades to lower costs before investing in more expensive renewable options.

1. REDUCING ENERGY COSTS Green Energy Solutions for Community, Corporate, and Industrial Facilities Bernie Kotlier IBEW-NECA / LMCC California Commerce, California March 17, 2010

2. The Case for Green Energy Cost of Energy (Electricity) Keeps Rising Climate Disruption, Including Water Supply National Security / Energy Independence Job Creation Stronger Economy GREEN ENERGY

3. Driving Forces - Examples: California Public Utilities Commission (PUC) Goals ALL New Construction ZERO Net Energy by 2020 Residential 2030 Commercial Likely to be a Model for the U.S. For Federal ARRA Funded Projects Creates Jobs Trackable, Reportable Employment Data GREEN ENERGY

4. Green Energy Electricity is a Dominant Theme in Green Energy Because Electricity is the Common Thread and Form in the New Sustainable Energy Economy. Some Key Sources: Photovoltaic Solar Electricity (“PV”) Wind Electrical Energy Solar Thermal Electrical Generation Electrical Energy Efficiency (EE), and … GREEN ENERGY

5. The Opportunities Most Compelling: COST SAVINGS. Numerous Opportunities; Some Applications: Distributed Solar PV for Homes, Businesses, and Institutions Energy Auditing of Buildings Applying Energy Efficiency Measures to Buildings Such as Highly Efficient Lighting and Lighting Control Systems GREEN ENERGY

6. In the Proper Order A) Energy Audit B) Energy Efficiency (EE) C) Renewable Energy (RE) GREEN ENERGY

7. Energy Audits are 1st Because We Need to Understand the Facility, its Energy Related Systems, Usage, and Costs BEFORE We Make Any Changes. Make Sense? Would You Like Your Doctor to Operate on You Without Tests and Diagnosis? If Your Car is Running Poorly Should the Engine be Replaced Before it is Diagnosed? And Then … Should the Most or Least Expensive Measures be Considered First? GREEN ENERGY

8. Makes Perfect Sense, Yet … Solar PV Jobs and Other Energy Related Retrofit Work is Often Done Without First Doing a Comprehensive Facilities Energy Audit Prospective Energy Savings are Not always Being Realized to Full Potential Because Property Owners and Managers Do Not Always Have All the Energy Information they Need to Make the Best Decisions The Energy Audit is the Diagnostic Tool that Provides the Comprehensive Data Required to Reduce Costs and Obtain the Best Return on Investment GREEN ENERGY

9. And Energy Efficiency is a Key Factor Facility Energy Efficiency (EE) is Making Interior and Exterior Electrical, Mechanical and Building Envelope Systems Work in a Highly Efficient Manner. Many EE Measures are Less Expensive Than Providing More Power from the Grid or from Distributed Generation. The Least Expensive Kilowatt is the One We Don’t Use! GREEN ENERGY

10. Why Energy Audits? $Billions in Federal Stimulus for EE projects Utility, and State incentives for EE projects EE Costs Only 2.5 - 3.0 Cents / KWH

11. Energy Auditing Audits Conducted by Expert Contractors Two Phases - Screening Survey – Identify the Savings Opportunities - Preliminary Energy Assessment (PEA) - Data Capture Quick introduction and summary, today

12. About Energy Assessments Goals of facility energy assessment: Find likely opportunities to save energy and save money Maybe retrofit or replace equipment Make informed decisions

13. Why Energy Assessments? Identify high-return energy efficiency upgrades: Reduce energy/overhead costs Improved Operational Efficiency Increase productivity via better indoor environment Increase building asset value … Increased Asset Value EE Upgrades

14. Why Energy Assessments? INCREASED ASSET VALUE Source: EPA “ENERGY STAR Buildings Partnership” Documentation $1 invested >> $2 – $3 increased value Increased Asset Value EE Upgrades

15. Energy Efficiency A Good Investment Source: ENERGY STAR Upgrade Manual for Buildings, EPA, 2004 Less risky and higher returns than S&P 500 composite

16. Where the Savings Come From

17. What Level of Savings Can Screening Surveys Help Uncover? EEM Area Possible Energy Savings Lighting Up to 25 – 50% of lighting energy use Window treatment Up to 10% of cooling energy use Motors Up to 10 – 20% of motor energy use Package units Up to 33 – 50% of package unit energy use Chiller systems Up to 25 – 40% of chiller system energy use Air handling Up to 25 – 50% of air handling energy use Enclosed Parking Ventilation Up to 25 – 50% of parking ventilation system energy use

18. Good Candidates for EE Measures 100% of 30 year-old buildings that have not undergone EE retrofits 5 10 15 20 25 30 0 Age of building (in years) Percentage of buildings in which common EEMs would be cost effective 35 (PLUS SOME BIG EXCEPTIONS) 30% of 10 year-old buildings that have not undergone EE retrofits 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100%
