OPPORTUNITIES FOR BUSINESSES TO DIRECTLY IMPROVE THEBOTTOM LINE THROUGH ENERGY EFFICIENCY 3rd May 2010 Kees Brinkman Managing Director
INTRODUCTION • Kees Brinkman: • Managing Director • Mechanical Engineer working in the energy field for 20+ years • EMANZ Accredited Energy Auditor • Enercon is an Energy and Utility Consultancy • Based in Christchurch • Six staff, all degreed engineers
DURING THIS PRESENTATION… • Why focus on reducing energy and carbon emissions? • Energy Management • Potential benefits of an Energy Audit • What are the potential savings? • Our experience with commercial and industrial clients
REASONS TO FOCUS ON ENERGY? • The economics are attractive! • Energy prices are increasing all the time • Any reduction in energy cost directly impacts on the bottom line • Once an Energy Audit is implemented, the cost of the audit is typically paid back in less than 100 days!
REDUCING CARBON EMMISSIONS • Reasons to reduce carbon emissions: • Emissions Trading Scheme leads to increased costs • Combats global warming • Ways to significantly reduce carbon emissions: • Improve energy efficiency (most common and economically attractive) • Switch to renewable fuels / suppliers
ENERGY MANAGEMENT SERVICES AVALIABLE TO IMPROVE THE BOTTOM LINE • Main Services • Scoping and Feasibility Studies • Energy Audits • Tariff Analysis and Tendering • Monitoring and Targeting Systems
FURTHERMORE… • Additional Services • Greenhouse Gas Assessments • Fuel Switching Feasibility Studies • Ongoing Energy Management • Audit Implementation and Project Management • Concept Design Reviews • Demand Side Management Analysis • Cogeneration System Analysis
WHERE TO START… • Energy Audit Scoping Study • Review the consumption of all sites and operations • Benchmark the figures to determine the most efficient path • Identify sites in need of Level 2 Energy Audit
LEVEL 2 ENERGY AUDIT – PROCESS • Energy Use Analysis • Calculate historic energy use and review bills • Determine where/when energy is consumed • Find target areas for energy reduction
LEVEL 2 ENERGY AUDIT – PROCESS • Site Visit • Kick-off meeting • Day-time inspections, including metering where appropriate • Afterhours inspections • Closure meeting
LEVEL 2 ENERGY AUDIT – PROCESS • Technical Analysis • Perform an energy split to determine where energy is used • Calculate savings from Energy Management Opportunities • Contact contractors to obtain capital costs
LEVEL 2 ENERGY AUDIT – PROCESS • Draft report • Client has opportunity to review • Review Meeting • Final Report
THE NEXT STEP… • Monitoring and Targeting • Monthly review energy consumption and bills for each site • Compare consumption and cost against predicted • Make recommendations towards changes needed • Perform Tariff Reviews • Ensure the most cost effective tariff is utilised
ENERGY AUDIT POTENTIAL SAVINGS… • Opportunities; less than one year payback • Typically 2 – 10% energy savings • Opportunities; between one and three year payback • Typically 2 – 10+% energy savings • Opportunities; greater than three years • Depends on the process • Are still investigated despite the long payback • May have production advantages
CASE STUDY – Large MDF Plant • Total Identified Savings • $1.4 million energy savings annually • 0.5 year average simple payback • Reduced annual carbon emissions of 2,000 tonnes (11%)
CASE STUDY – Office Building • Total Identified Savings • 13.2% energy savings annually • 2.8 year average simple payback • Major Opportunities Found • Improve AHU control and lighting efficiency
CASE STUDY – Canterbury Museum • Kelvin Nolly • Could not be here today • Total Identified Savings • $79,000 energy savings annually (36.9%) • $2,500 implementation cost
CASE STUDY – Canterbury Museum • Opportunities • Optimising the electricity demand controls on the BMS • Reducing fresh air being supplied to spaces when not required • Switching off plant at night • Fixing the humidity controls for AHU9
CASE STUDY – Canterbury Museum • Daily Load Profile 1. Under floor heating 2. Office loads 3. Space heating 4. Base load 5. Day lighting
CASE STUDY – Canterbury Museum • Optimising BMS electricity demand controls • Saved $34,000 • BMS load shed HVAC systems to avoid Control Period demand charges • Another program was installed to avoid spot prices which conflicted causing large Network Charges • Solved by prioritising programs or avoiding spot market
