29. APPROCHES TO SAVE ENERGY
• Self Energy Audits – Identify best practices within your depts.
• Identify those areas that use the most energy – Remember
HVAC accounts for 60%+ of your energy consumption, Make a
plan, set some goals
• Involve the whole staff, cultivate a behavior save energy. Save
Power , Save Water.

30. HOW TO SAVE ENERGY INSIDE THE HOSPITAL
• SWITCH OF MONITORS AFTER USAGE
• KEEP ALL DOORS CLOSED WHEN NOT IN USE
• OPENING DOORS MULTIPLE NUMBER OF TIMES TO BE AVOIDED
• SWITCH OFF LIGHTS WHEN NOT NEEDED
• SWITCH OFF POWER TO AC’s,
• USE MAXIMUM DAYLIGHT DURING THE DAY
• TRY TO CALL THE NEAREST LIFT INSTEAD OF CALLING MULTIPLE LIFTS

31. WATER- HOW TO SAVE?
• REPORT TO THE ENGINEERING
DEPARTMENT WHEN YOU SEE A TAP
LEAKING/ SHOWER LEAKING
• CLOSE WATER TAP WHEN NOT IN
NEED
• ALL CLOSETS ARE WITH DUAL
SWITCH CISTERNS, USE THEM
ECONOMICALLY
• ALL URINALS ARE WITH SENSORS

32. ENGINEERING DEPARTMENT FUTURE
PROJECTIONS
• COMMISSIONING OF NEW 1250KVA DIESEL GENERATOR.
• GARBAGE STORE BUILDING / HAZARDOUS BUILDING – WASTE
MANAGEMENT
• DISASTER RECOVERY DATA CENTER - IT
• WE ARE INSPECTING AND RECTIFYING SNAGS ON EACH RESPECTIVE AREAS
TO ENSURE SMOOTH OPERATION
