2 Reaching Your Energy Potential Key Ideas Take a systematic measured approach for the necessary focus and follow through: Windmill fun, but want continued success. Make informed choices on upgrade measures: understand the options and impact, the strategic ordering, make the best choice for you. Fit efficiency into your business model: required return, planning horizon. Plan for continued success w/ ongoing monitoring, maintenance and training.

3 Taking a strategic approach to Energy Management Get a handle on where you are. Develop a vision for where you want to go. Chart a path to bridge the gap.

4 Taking a systematic approach ENERGY STAR Guidelines For Energy Management A Continuous Improvement Process Plan, Do, Check, Adjust. Feedback Loop Essential. SEDAC audits help w/ assessment, action plan possibilities, ID of financial assistance. We can also help review bids, find products, and service providers.

5 Where You Are At Look at the big picture. Review Motivators for Change: Economic increasing costs driven by increased demand, depleting supplies, increased production costs. Environmental global climate change, accumulated waste, disturbed habitat. Social- laws, regulations, codes, security issues. Recognize Challenges: Cash flow, planning horizon Awareness Culture (values, habits, policies of those who live, work, or are stakeholders in the building). (e.g. if it s not broke don t fix it, dress for the weather?)

6 Where You Are At Assess Performance Determine major energy costs: Depends on function of building Office lighting Restaurant Kitchen Grocery - Refrigeration Utility rates, electric often costs more than natural gas in $ per Btu. We care more about $ than therms or Btus We care about services heating, cooling, etc Compare vs. similar facilities.

7 Benchmark Performance Where do you fall? Energy Star Target Finder

8 What s Energy Efficiency worth to you? 50% Energy Cost Savings 30% 15% Moderate Cost Best Practices Capital Intensive, Significantly Beyond Code Intervention Low Hanging Fruit Investment Costs Increased investment increases savings, but w/ diminishing returns Low hanging fruit (~15%, tune up, turn down/off, seal the cracks, lighting) Moderate Cost (~30%, tighter control, upgrade equipment at end of life) Capital Intensive (50+%, system redesign, replacements, robust envelopes) Doing nothing (forgone savings, higher and increasing energy and maintenance costs, lower comfort)

9 Where You Want to Go Develop a Vision Statement -Description of a Desired End State (e.g. carbon neutral, best in class, percent execution of best practices or cost-effective practices, do fair share for climate change, stay afloat). Break down your Vision into intermediate Goals or accomplishments that fulfill your vision. Set the goals mindful of your current performance (e.g. get to average on energy use intensity). Include Metrics and dates (Glide path, stepped changes) Dare to set a stretch goals that requires innovation.

10 Getting There Making Informed Choices Review options for efficiency measures Quantify impact Prioritize

11 Review Options for Efficiency Apply tried and true methods or get specialized assistance. Common options: Fix, control, upgrade/replace, insulate, seal SEDAC s Top 10 list and fact sheets. Use Utility Standard incentives application as an outline of options. Don t Forget to right size HVAC equipment and lighting (don t replace in kind). Use a designer/engineer.

12 Establish Priorities for Action Items Review Objectives (e.g. Cost savings, Thermal comfort, reduced carbon footprint, LEED certification). Needs (e.g. failed equipment). Technically Appropriate (for your site.) Consider Ordering of Projects: Start w/ orientation and envelope for new construction. Start with end-use requirements for existing buildings.

13 Establish Priorities for Action Items Make sure your short-term actions support your long-term goals: All projects are energy projects. Repair w/ efficient choices (e.g. windows) Implement phases mindful of the end goal (such as Building Automation System) Install network ready thermostats. Use open protocols.

14 Making Your Project Economically Viable Manage cash flow, make case to board/yourself Consider the total cost of ownership, not just first costs (operations usually the largest cost). Pay more now, save year after year. Get multiple bids to establish market costs. First Cost Cost Operating Costs Disposal Time

15 Making Your Project Economically Viable Quick Returns Medium Returns Long Returns Tune up Thermostats Occupancy Sensors Timers Variable Speed Drive Insulation Lighting Insulation Boilers/Chillers Windows Bundle projects to achieve desired economics

16 Making Your Project Economically Viable Recognize productivity benefits. Consider the marginal cost of an efficient upgrade. Have projects researched and ready to go for short term funding windows. Make maximum use of available financing, grants, and services.

17 Plan for Continued Success Continue to evaluate and assess goals: Monitor operations Ongoing training Ongoing maintenance Don t expect success only.
