Transcript of Energy Audit (Basic concepts)

ENERGY AUDIT What is an energy audit? An energy audit is a systematic procedure for optimal knowledge of the profile of energy consumption in a building, installation, or construction process, identifying and assessing the potential for energy savings from the technically and economically. Objectives of an Energy Audit Get reliable knowledge of energy consumption
Identify where and how energy is consumed and factors affecting their consumption
Optimize energy supply.
Improving procurement of electricity and fuel
Identify energy costs
Identify and evaluate opportunities for savings and improving energy efficiency
Eliminate energy losses
Maximize system efficiency
Reduce emissions per unit of production
Assess the opportunities for diversification of energy and its impact on energy cost
Explore the possibility of using renewable energy What benefits do we get from the completion of an energy audit? -Reduction of energy costs by optimizing energy consumption
-Increasing the useful life of the equipment
-Increased competitiveness
-Improving corporate image by contributing to environmental care
-Access to public support for the implementation of Energy Studies WHAT WE ANALIZE/STUDY/EVALUATE PRODUCTION PROCESSES ENERGETIC SUBMINISTERS EFFICIENCY Electricity FUEL OTHER RESOURCES OF ENERGY -Procurement

-... Conducting a study of the operations and energy consuming equipment involved: -Study of the production processes / energy / level of utilization of the production capacity of the facility.
-Identification of the basic operations and process lines assigning energies used.
-Identification of systems and equipment energy suppliers.
-List of elements involved in processes: Number of employees, surfaces, seasonal processes, analysis of energy ratios, ...
-Record consumption of equipment, systems and parts of the process.
-Study of the servicing and maintenance of equipment and systems and their technical specifications.
-Thermal performance of the installation: Envelope, enclosures, climate zones, ....
-Electrical: Rush, transformation, internal distribution, ...
-HVAC: heating, cooling, air quality.
-Lighting System: Optimization of consumption. Natural and artificial light, sectorization, ID, ...
-Hot Water: Use efficient systems.
-Electric motors: Boot Control, consumption optimization.
-Other facilities such generators or capacitor bank.
-Boilers: Combustion optimization and utilization of waste heat for hot water or heating.
