Abstract: This paper presents simple walk though energy audit for the lighting load of library section of educational institution. Lighting is a major load in case of educational institution particularly in library section. Lighting is an area which provides a major scope for achieving energy efficiency at the design stage by using the modern energy efficient lamps. Innovation and continuous improvements in lighting design has given big energy saving options. Implementation of energy audit can reduce the wastage of energy and gives good practice of energy conservation. In this paper library loads have been surveyed tabulate, energy saving measures is analyzed involves the replacement of low efficient lighting by high efficient lighting. The outcome of evaluation namely annual consumption reduction, greenhouse gas reduction and payback period is presented.

Keywords: Energy audit, lighting, payback period, energy conservation.
