ENERGY STUDY
ENVE Energy, with its expert engineer staff, performs measurements at the energy consumption points of your business in line with international standards and helps you to direct your efficiency-increasing investments correctly by preparing detailed survey reports.
WHAT IS ENERGY STUDY AND WHY IS IT DONE?
Energy audit is carried out in order to determine the energy saving potentials, energy wastes and greenhouse gas emissions, and to reveal the regenerative or preventive measures related to them with technical and economic dimensions. Within the scope of energy audits, the following audit profiles are handled on an annual basis;
Input Profile: Types of energy entering the business or building (natural gas, fuel oil, coal, electricity, steam/hot water, etc.), unit energy quantities (energy amounts carried by unit weight or volume of inputs in kWh), usage amount – time graphics.
Waste Profile: Types (flue gas, hot gas/water, steam, etc.), causes of formation, amount – time graphs of recyclable energy wastes from heating/cooling systems, energy conversion systems or production processes.
Loss-Leakage Profile: The amount of energy lost due to thermal insulation deficiencies in buildings and equipment, steam/gas/water/fuel leaks/leakages in equipment, and incompatibilities in electrical systems that can be prevented.
Inefficiency Profile: The amount of energy wasted and avoidable due to energy inefficient equipment or process application.
Waste Profile: The amount of energy wasted on equipment that is overused, in standby or in wasted equipment in heating, cooling, lighting, office needs and similar areas.
Emission Profile: Amounts of greenhouse gases based on energy types in the input profile.
Energy Management Profile: The adequacy of the energy manager/management unit in the enterprise, the procedures applied, the awareness level of the employees and the top manager's view on energy management.
WHAT ARE THE STEPS OF ENERGY STUDY?
Preliminary Study: Study profiles in the business or building are analyzed with the help of documents, interviews, observations and, when necessary, point measurements. Prevention and/or recovery potentials are estimated. The measures that can be applied for these are determined together with their approximate costs and recovery times. Suggestions are developed to eliminate the deficiencies observed in the energy management profile. The studies and work program that are deemed necessary to be included in the detailed study are determined. Preliminary studies are completed within a maximum of ten working days, together with the preliminary study report.
Pre-Study Briefing: A one-day pre-study briefing is given to the managers, including the top manager of the enterprise, and to the employees determined by the senior management. In this briefing; General introduction of energy efficiency together with its benefits and costs, exemplary practices in the world and in Turkey, information on preliminary study results and measures that can be taken are given and useful documents are distributed, questions of those attending the briefing are answered and their opinions are taken. It is stated that VAP can be prepared and the decision of the top management is requested.
Detailed Survey: The prevention and/or recovery potentials are estimated with a maximum error rate of ± 10% by making measurements and calculations under operating conditions on subjects deemed appropriate to be included in the detailed survey according to the preliminary survey results. Precautionary options that can be applied by using the results of the preliminary and detailed studies are analyzed with their technical and economic features. In this context, by choosing the most appropriate measures, information guiding the productivity-enhancing projects that can be prepared later is revealed.
Reporting: The formats of the preliminary study and detailed study reports have been determined with the “Communiqué on the Procedures and Principles to be Applied on Authorizations, Certifications, Reporting and Projects to be Made under the Energy Efficiency Law No. 5627” published in the Official Gazette dated 06.02.2009 and numbered 27133.
