## Presentation of Energy ConservationinGovt. BuildingsofMaharashtra State.

## Energy Saving

- Energy Saved is Energy Generated.
- Saving of Energy is the need of the day.
- Government is one of the major consumer of Energy.
- The Govt. has to lead others by taking effective steps to save the energy

## Energy Saving

***278 million units*** of energy per annum are consumed by Maharashtra State Government Office Buildings
- This is equal to ***105 MW*** Generation during working hours under the assumption of 10 hours /day, 22 days /month, 12 months /year.
- One unit saved is ***TWO*** units generated.
- Annually ***Rs.111 crores*** are spent by the Government on energy bill .

## Energy Saving

- Energy Efficient Lamps and Equipments can save energy bill up to 30 %.
***100/60/40 watts*** bulbs can be replaced by ***CFL lamps*** of ***22/11/9 watts*** having power factor more than 0.9.
***40/36W Fluo. fittings*** can be replaced by ***28W E+/T5  fluo. fittings*** or their ***chokes*** by ***electronic chokes***.

## Four pillars of successful Energy Management

## Four pillars of successful Energy Management : Key Elements

- Successful energy management programme needs the total support of senior management.
- The other important requirements are
- A well-charted strategy plan.
- An effective monitoring system.
- Adequate technical ability for analyzing and implementing energy saving options.
- In any organization, which does not already possess an energy efficient ethics, good communication downwards from senior officials will be vital first step.
- Active participation & planning for the energy management

## Ways of Energy Conservation

- Awareness
- Replacement of conventional fittings with ***E+ fluo. fittings ***
- Replacement of conventional pumps with ***submersible pumps/energy efficient pumps ***
- Replacement of old water coolers with ***energy efficient water coolers***
- Replacement of GLS lamps with ***CFL lamps***
- Incorporating ***timers*** for passage lights
- Incorporating ***digi guard***s for ACs
- Incorporating ***DPSD*** for compound & street lights

## Ways of Energy Conservation

- Replacement of electric water heaters with ***solar water heaters***
- Replacement of water coolers with ***heat pumps***
- Replacement of resistance type regulators with ***electronic regulators***
- Replacement of conventional chokes with ***electronic chokes ***
- Incorporating ***VFDs*** for hydro pneumatic systems, pumps & central AC plants
- Incorporating ***3VF drives*** for lifts
***Smart Card (SIM) ***based Power Controller
