To obtain the objectives set in an Energy Audits, it is important that one should perform an analysis, study and assessment of the following aspects of the energy audit:
• Electricity: Single-line diagram, procurement, consumption, billed and development concepts, concurrency ratio, use of emergency generators, power equipment inventory of consumer.
• Fuel: Type of supply, procurement, consumption, cost of different concepts and their evolution billed.
• Self power: Type of facilities, production and development, recruitment, determination of consumption and excess.
Other sources of energy such as steam, hot gases, hot water and chilled: Recruitment, consumption trends, cost of different items billed to other sources of alternative energy.
Production processes
This is the study of the operations and energy consuming equipment involved. And such study should include the following:
• Study of production processes and their energy needs and the level of utilization of productive capacity of the facility.
• Identification of the basic operations and process lines assigning the energy used
• Identification of systems and equipment suppliers of energy and its links with other operations.
• List of elements involved in the process: Number of employees, surfaces, seasonality of processes, analysis of energy ratios.
• Record consumption of equipment, systems and parts of the process.
• Study of maintenance and upkeep of equipment and systems and their technical characteristics.
Study of the efficiency of the application of horizontal technology and general services is important to identify and analyze their potential for energy savings and diversification.
Other factors that need to be looked into building experts are as follows:
• Thermal performance of the installation: Surround, enclosures, climate zones
• Electrical: Rush, transformation, interior layout, harmonic, reactive, equal distribution of loads.
• HVAC: heating, cooling, air quality.
• Lighting System: Optimization of consumption.
• Compressed air distribution network.
• Hot Water: use efficient systems.
• Electric motors: boot control, optimization of consumption.
• Other facilities such generators or capacitor banks.
• Boilers: Combustion optimization and utilization of residual heat for hot water or heating.
