1. INTRODUCTION
Energy cost is a significant factor in economic activity, on par with factors of production like capital, land and labor. The imperatives of energy shortage call for energy conservation measures, which essentially mean using less energy for the same level of activity.
In this paper we discusses the Conservation, Efficiency, Audit, Fundamentals, Differences and methods, the Objectives of Energy Conservation, Definition of Energy Audit, Scope, short term, medium term and long term measures to be taken for Conservation are discussed. The audit programs, methodology of saving energy through various means namely: Audit, House Keeping, Lighting, Personnel, Capital Investment, Monitoring are elaborated.
Energy Audit attempts to balance the total energy inputs with its use and serves to identify all the energy streams in the systems and quantifies energy usages according to its discrete function.
Energy Audit helps in energy cost optimization, pollution control, safety aspects and suggests the methods to improve the operating and maintenance practices of the system. It is instrumental in coping with the situation of variation in energy cost availability, reliability of energy supply, decision on appropriate energy mix, decision on using improved energy conservation equipments, instrumentations and technology.
2. EXECUTIVE SUMMARY
A comprehensive energy audit of Hindustan Machine Tools (Food Processing Machinery Unit) was entrusted to us. The objective of the audit was to carry energy audit, identify the avenues of savings potential and various energy conservation proposals with techno economic analysis.
Following are Few Important Energy Conservation Proposals along with details regarding annual savings and cost benefit analysis.
Recommended Energy Saving Measures.
Supply from MSDCL:
Supply voltage to be reduced to the optimum so that the lighting energy consumption is reduced without compromising the comfort level.
Lighting:
Reduce excessive illumination levels to standard levels using switching, delamping, etc.
Aggressively control lighting with clock timers, delay timers, photocells, and/or occupancy sensors.
Install efficient alternatives to incandescent lighting, mercury vapor lighting, etc.
Efficacy (lumens/watt) of various technologies range from best to worst approximately as follows: low pressure sodium, high pressure sodium, metal halide, fluorescent, mercury vapor, incandescent.
Consider painting the walls a lighter color and using less lighting fixtures or lower wattages.
Use task lighting and reduce background illumination.
Air Conditioning:
Eliminate or reduce reheat whenever possible.
Don’t oversize cooling units. (Oversized units will “short cycle” which results in poor humidity control.)
Purchase only high-efficiency models for HVAC window units.
