  2. Section I Common Area Lighting

  3. Common areas identified for provision of Energy Efficient Lighting are Corridor Staircase Toilets

  4. Existing practice • Provision of no. of 40 / 36 W Box type Fluorescent fitting according to the size of the common area. • Proposed • Provision of 1 no. 1 x 11 W CFL fitting • Low cost • Low energy consumption

  5. Pay back period for the use of CFL fitting instead of conventional 1 x 40/36 W box type FL fitting

  6. A case study for the O/o the CGMT, Anna Salai ,Chennai – 2

  7. A case study for the Tamilnadu Telecom Complex ,Ethiraj Salai,Chennai - 6

  8. Section II Solar water heaters

  9. UTILISE THE NATURE SOLAR ENERGY CAN BE USED TO HEAT THE WATER SOLAR WATER HEATERS

  10. A solar water heater • Collects solar energy through a collector • Store water in an insulated tank • Based on the collector system, solar water heaters can be of two types • No.1 Solar water heaters based on Flat plate Collectors • Solar radiation is absorbed by  flat plate collectors. • It consist of an insulated outer metallic box covered on the top with glass sheet. • Inside there are metallic absorber (selectively coated) sheets with built in channels or riser tubes to carry water. • The absorber absorbs the solar radiation and transfers the heat to the flowing water.

  11. Flat plate Collectors

  12. Evacuated Tube Collectors • Collector is made of double layer borosilicate glass tubes evacuated for providing insulation. • The outer wall of the inner tube is coated with selective absorbing material. • This helps absorption of solar radiation and transfers the heat to the water  which flows through the inner tube.

  13. Solar water heaters based on Evacuated Tube Collectors

  14. Application • Solar water heaters of 100-500 litres capacity are suited for Inspection quarters • Larger systems can be used  in training centre hostel etc. • Hot water at 60-70 C  can be obtained .

  15. Agencies in DGS&D RC • Skylark Thermal Energy Systems, Pune • Tata BP Solar India Ltd.,New Delhi • Solar Energisers P Ltd, Bangalore • Kotak Urja P Ltd, Bangalore • Enolar Systems, Bangalore • Bipin Engineers P Ltd, Pune • Sudharshan Saur shakti P ltd, Aurangabad

  16. A case study for the IQ @ TE,Katpadi

  17. Solar water heating system practically requires NIL maintenance and life period is approximately 15 Years whereas water heaters require periodical maintenance of replacement of elements etc. and life period is approximately 7 years ,which further reduces the payback period Savings after the pay back period / year is 365 x 160 = Rs 58400/-

  18. A case study for the officers’ Hostel @ RGM TTC,Chennai (Already implemented)

  19. A case study for the officers’ Hostel @ RGM TTC,Chennai ( contd…) • Above system was commissioned during July 2004 • Savings to the BSNL achieved till date = 3 years – 8 months( pay back period) = 2 years 4 months x 2.437 lakhs (savings per year) = 5.7 lakhs
