3 <This is a general building energy audit report template to guide ESCOs that will perform normal or detailed energy audits in buildings in the framework of the project Energy Sector Technical Assistance Project, Consulting Services for the Energy Efficiency. The energy audits aim at identifying energy saving opportunities in the envelope and energy systems of the building. However, the main purpose of the audits is to analyse concrete cost- effective energy efficiency investments that could attract financing by Financing Institutions with possible involvement of ESCO contracts. This template is based on the official Building Energy Audit Report Format Sample (Reference e.g. Ministry of. XXXX) adapted for the case of ESCO-type auditing. All information included in the official audit report templates are included in the present templates slightly reorganised and with additions to serve the purpose of an audit carried out by ESCOs. It is noted that general audit templates serve as a guide only. The auditor should adapt this template to the particularities of each audit case, as required. Finally, this template should be seen in conjunction with the training for ESCOs during which, specific methodological issues and auditing techniques will be analysed and presented to participating ESCOs.> CONTENTS In this section, section titles, sub titles and appendices as numerated by the related sections will be given with page numbers in a separate page.

(1 MWh= ToE or 1 ToE = MWh) TABLE Ref1: Fuels/electricity characteristics, costs and emission factors Energy form Original unit Lower Heating Value, (ToE/original unit) Energy price (TRY/ToE) CO2 emission factor (kg CO2/ToE) Electricity E Electricity purchased 1000 kwh see note 1 Epr Electricity produced 1000 kwh see note 2 see note 3 Conventional fuels F1 Mazout (heavy fuel oil) ton F2 Diesel 1000 l F3 LPG ton F4 Natural gas 1000 Nm 3 Other F Thermal energy purchased Gcal see note 4 Renewable energy RE1 Renewable energy (biomass, biogas, etc.) (please specify) RE2 Notes: 1. CO2 emission factor for Electricity purchased refers to the final electricity at the meter of the consumer 2. Please ensure that the study avoids double counting of fuel costs (cost for electricity produced e.g. by a CHP and the cost of fuel used to produce this electricity). 3. Please ensure that that the study avoids double counting of CO2 emissions (emissions associated to electricity produced and emissions from fuels used to produce electricity). 4. CO2 emission factor for thermal energy purchased is calculated on the basis of the emission factors of the fuels used by the producer of thermal energy (if produced by RES the emission factor is 0) and the generation / distribution losses until the meter of the facility. 5
