What does Efficiency mean?
Efficiency means all changes that result in a reduction of inputs used for a given service or level of activity.
This reduction in the input consumption is not necessarily associated to technical changes, As it can also result:
From better organization and management
Better MIS & Control
this concept is called efficiency

Energy Efficiency
Energy Efficiency means: Using Less Energy to achieve same or better output
Energy Efficiency Project refers to:
Energy Efficiency Most Cost –Effective Solution
Reducing the Energy Supply/Demand Gap
Mitigating Climate Change Impacts
Without compromising Economic development

Energy Efficiency
The first aim should be:- To gain control on consumption and costs by assessing current use.
- by taking steps to incorporate energy efficiency into the corporate culture.
This involves:• Identifying, and quantifying, organization’s major
users of energy
• Reviewing energy purchasing strategies
• Choices to make sure that the most appropriate energy sources bought at the right prices/time

Energy Efficiency (EE)
What we understand under EE
Energy efficiency means:
- How effectively energy is being used for a given purpose.
Why energy efficiency:
Energy resources are limited
Restricted global fossil energy resources lead to increasing energy costs
More energy efficiency can reduce dependency of energy imports
Increased competitiveness for Indian industries

Major energy consuming IT equipments
Computer Hardware:• Computer Servers• Computer Desktops• Laptops• Printers• Routers and Switches• Other Networking equipments
• Computers and monitors account for 40-60% of the energy used by office equipment.
• The average computer & monitor use 30% of their energy even while idle.
19.04.2023 Seite 16Page 16
Computer Power Back-up Systems
Uninterruptable Power Supply (UPS) DG Sets
Over sized UPS:UPS systems have poor performance at loads below 25% and efficiency is lost in this process.
DG Sets:The generator should be loaded between 65% to 85%. The loading beyond 85% does not give any extra efficiency, but it decreases engine life.
19.04.2023 Seite 17Page 17
Office Equipments
• Photocopiers• Vending Machines• EPABX Systems• Fax Machines
Photocopiers: It uses the most electricity and do not have to be left on continuously. The equipment not only wastes electricity but also generates heat that leads to a stuffy office or added air conditioning costs.

General Lighting Systems
• Bulbs • Tube Lights• CFLs• LED Lamps
Lighting systems: • Select ballasts and lamps carefully with high power factor
and long-term efficiency in mind. • CFL consumes 1/3rd of energy compared to Indecent Bulb• LED consumes 1/10th of energy compared to Indecent
Bulb

Lighting
Use T-5 (28 W tube light in place of standard T-8 & T-12 tube

Motor DOs
Motors should be operated at rated voltage & balanced supply.
Carry out preventive maintenance and condition monitoring schedule regularly.
Check the RPM as per monitoring schedule.
19.04.2023 Seite 21Page 21
Motor DONTs
Avoid frequent rewinding of motors.
Rewound motors practically have an efficiency loss of upto 5%.
This is mainly due to increase in no load losses.
Hence use such rewound motors on low duty cycle applications only.
19.04.2023 Seite 22Page 22
Motor Dos
Use energy efficient flat belt instead of V-Belt to avoid transmission losses.
Expected saving will be 3 to 5 %.
19.04.2023 Seite 23Page 23
Power Factor Dos
Improve power factor by installing capacitors to reduce KVA demand charges and also line losses within plant.
Carried out Health check up at regularly.
