27. 9 Mantras to
Save
Electricity at
Home

28. Mantra – 1:
Switch off the
Equipment When
not in Use

30. Mantra – 2 :
Regular Cleaning
of AC filter &
Use of Natural
Lighting

31. Air Conditioning System:
An air conditioner's filters, coils, and fins require regular
maintenance for the unit to function effectively and efficiently
throughout its years of service.
Neglecting necessary maintenance ensures a steady decline in air
conditioning performance while energy use steadily increases.
 Routine cleaning of AC filters, reduces energy consumption by
5 to 15 %.
 Clean the evaporator coil
 If coil fins are bent, straighten them
 Inspect the window seals – maintains cool air escaping
 Clean the drain channels to prevent clog
 Split AC - Clean the debris from fan, compressor and condenser

32. Mantra – 3 :
Use Star Rated
Equipment

33. FRIDGE

34. AIR CONDITIONER

35. Mantra – 4 :

38. Changes in Lighting Schemes

39. Energy Efficient Fluorescent Lamps
Types of FL

40. Energy Efficient FL
• Several types of FLs are used in lodging areas – lobby or
office area
• Types of FL depends on
– Lamp Life
– Energy efficiency
– Regulated power
– Quantity of colour it transmits
• Styles of FL
– T-12 – 12/8 or 11/2 inch dia
– T-8 – 8/8 or 1 inch dia
– T-5 – 5/8 inch dia

41. – Recommended style – T-8 because
• Cost effective
• More illumination
• Better colour
• No flickering
– T-12
• poor colour rendition and causes eye strain
– T-5
• more energy efficient
• Best colour
• Not cost effective
• Cost Comparison - For 36 W, T5 = Rs. 250/- & T8 = Rs. 125
