Energy Audit - Checklist

Energy Audit Quick Checklist

Energy Audit Checklist gives an overview of Preliminary Energy Audit of a Facility. This refers to the basic data capturing for assessing the present status of Energy Efficiency. This Energy Audit checklist is only for a quick assessment and not a detailed Energy Audit. For a detailed study Energy Audit experts from this field who are B.E.E. Certified need to make a comprehensive Energy Saving Plan for Energy Optimization.

This is NOT a Energy Audit Questionnaire. To download Energy Audit Questionnaire please Click Here.

a)         Lighting:-

♦    Is your facility using the most energy efficient lighting options (fluorescent mercury vapor, etc.)?

♦    Are there areas that have excessive or unneeded lighting?

♦    Are you making effective use of available lighting, such as natural sunlight?

♦    Have you installed lighting management equipment such as dimmers, timers and sensors?

b)         Building Envelope:-

♦    Is the building well insulated?

♦    Does weather stripping around doors and windows need to be replaced?

♦    Are cracks around doors, windows and foundations properly sealed?

♦    Are there open doors around loading docks or other frequently accessed areas?

c)         Heating and Cooling:-

♦    Arc   furnaces,   boilers   and   air conditioning systems   operating efficiently?

♦    Is there a regular maintenance and update schedule for these systems?

♦    Are filters replaced regularly?

♦    Is the building properly ventilated?

d)         Motors and Equipment:-

♦     Is your equipment maintained so that it is operating at maximum efficiency?

♦     Is equipment load compatible with manufacturer specifications?

♦     Are machines shut down when not in use?

♦     Are fan belts at the proper tension and in good condition?

e)  Energy Behavior:-

♦     Are   lights, fans   and   equipment (computer, printers, etc.) turned off when not in use?

♦     Are building temperatures set back when not in use?

♦     Are thermostats set to higher or Lower than necessary in summer and winter?

♦     After finding answers to the check list   and   identifying areas   of improvement, following possibilities maybe   explored   as   energy conservation measures.
