Slide 1: Energy Management and Efficiency
ENERGY MANAGEMENT AND EFFICIENCY Engr. Edwin Santillan 4 May 2016
Slide 2: Energy Efficiency vs Energy Conservation
Energy Efficiency vs Energy Conservation
Slide 3: What is Energy Efficiency (EE)?
What is Energy Efficiency (EE)? Using less energy to provide same service or same output. Energy efficiency is achieved when energy intensity in a specific product or process is reduced without affecting the output, product quality, level of comfort, or safety and environmental standard
Slide 4: Energy Efficiency
Energy Efficiency Decreasing energy consumption trend doesn’t necessarily mean being energy efficient! Year kWh Product OutPut 2010 1,000,000 100,000 2011 850,000 70,833 2012 700,000 46,667 2013 500,000 25,000 2014 300,000 10,000
Slide 5: Energy Efficiency
Energy Efficiency Energy Intensity Index (EII) -quantity of energy required to perform a particular activity, service or product Examples : - kWhr per unit of product - kWhr per occupancy - kWhr per area
Slide 6: Benefits of Energy Efficiency
Benefits of Energy Efficiency • Empowered to make informed decisions • Empowered to uplift the standard of living • Improved performance through its effect on services, operations and maintenance • Lower overhead costs • Improved ability to withstand future energy cost increases or energy curtailmen
Slide 7: Energy Efficient Practices and Opportunities
Energy Efficient Practices and Opportunities Efficient operating procedure (no cost) Efficient equipment alternatives (with cost) Better building design and envelope Better maintenance program Enhanced awareness program
Slide 8: Efficient Operating Procedure
Effficient Operating Procedure -streamlining processes by eliminating waste while continuing to deliver value to users/customers
Slide 9: Efficient Operating Procedure
Efficient Operating Procedure Set the thermostat at comfortable temperature level, DOE’s recommended temperature setting is at 24°C to 25°C There’s significant energy saving for every degree increase in thermostat setting
Slide 10: Efficient Operating Procedure
Efficient Operating Procedure • Standby power is electric power consumed by equipment / appliances while they are switched off, in a standby mode or not performing their principal service • Switch off or unplug computers, water coolers and other appliances that are not needed after office hours
Slide 11: Efficient Operating Procedure: Water Dispenser
Efficient Operating Procedure Water Dispenser Cooling = 90w Heating = 550w If not in use, do not leave the cooling and heating switches in “ON” position. If possible, switch them ON only a few minutes before usage
Slide 12: Energy Efficient Practices and Opportunities
Energy Efficient Practices and Opportunities Efficient operating procedure (no cost) Efficient equipment alternatives (with cost) Better building design and envelope Better maintenance program Enhanced awareness program
Slide 13: Efficient Equipment Alternatives
Efficient Equipment Alternatives Lighting System 65% Savings
Slide 14: Efficient Equipment Alternatives
Efficient Equipment Alternatives Lighting Fluorescent Lamps LED
Slide 15: Efficient Equipment Alternatives
Efficient Equipment Alternatives Consider using inverter aircon, it consumes less power compared to conventional units during entire operation by reaching the desired temperature quickly and keeping the temperature from drastically fluctuating. Inverter aircon can save up to 30% of the aircon energy
Slide 16: Efficient Equipment Alternatives
Efficient Equipment Alternatives Conventional aircon vs. Inverter-type aircon The inverter aircon is more energy efficient than its conventional counterpart by as much as 28% during the first hour of operation. CONVENTIONAL ACU KWHR/Hr = 0.812 Savings = 28% INVERTER ACU KWHR/Hr = 0.585
Slide 17: Efficient Equipment Alternatives
Efficient Equipment Alternatives Water and energy are closely interconnected. Efficiency program that saves water will also save energy • Install low-flow faucets • Use low volume or dual flush • Use water – free urinals
Slide 18: Energy Efficient Practices and Opportunities
Energy Efficient Practices and Opportunities Efficient operating procedure (no cost) Efficient equipment alternatives (with cost) Better building design and envelope Better maintenance program Enhanced awareness program
Slide 19: Better Building Design and Envelopes
Better Building Design and Envelopes
Slide 20: Better Building Design and Envelopes
Better Building Design and Envelopes
Slide 21: Better Building Design and Envelopes
Better Building Design and Envelopes • To reduce solar heat gain, use efficient film/tint on glass panes and windows
Slide 22: Better Building Design and Envelopes
Better Building Design and Envelopes • In addition to window film/tint, use solar screens especially when solar heat is intense at noon time
Slide 23: Better Building Design and Envelopes
Better Building Design and Envelopes Sun Shading and Curtain Wall Net Lima, BERDE certified by PhilGBC (Philippine Green Building Council, Building for Ecologically Responsive Design Excellence)
Slide 24: Better Building Design and Envelopes
Better Building Design and Envelopes • Instead of jalousie type, use swing or sliding type windows
Slide 25: Energy Efficient Practices and Opportunities
Energy Efficient Practices and Opportunities Efficient operating procedure (no cost) Efficient equipment alternatives (with cost) Better building design and envelope Better maintenance program Enhanced awareness program
Slide 26: Better Maintenance Program
Better Maintenance Program • Establish an operating and maintenance program for the major electrical equipment and facilities • Regular inspection with the aid of thermal scanning is an effective predictive maintenance practice
Slide 27: Better Maintenance Program
Better Maintenance Program • Regularly clean and maintain airconditioning units • It could improve aircon energy consumption by 5% to 15% • It will also give quality indoor air Source: familyhandyman.com
Slide 28: Better Maintenance Program
Better Maintenance Program • Regularly clean and maintain electric fans and blowers, it could save up to 2% in energy cost • It also gives peace of mind that the equipment is safe and properly functioning
Slide 29: Energy Efficient Practices and Opportunities
Energy Efficient Practices and Opportunities Efficient operating procedure (no cost) Efficient equipment alternatives (with cost) Better building design and envelope Better maintenance program Enhanced awareness program
Slide 30: Enhanced Energy Awareness
Enhanced Energy Awareness •Encourage the value of participation and cooperation among the staff and management in improving energy efficiency through: •information campaign •training •team building •appraisal SWITCH OFF when not in use
