Energy Audit Guide in Buildings

Energy Audit Guide in Buildings, Industries and Transportation

The Guide aims to facilitate energy audits in Greece in accordance with the requirements and specifications of Law 4342/2015 to improve energy efficiency. Energy control is defined internationally as the systematic control and analysis of the use and energy consumption of a unit, building, system or business. The objective of the audit is to quantify energy flows and potential energy efficiency improvements. The check shall be accompanied by the relevant reference thereto.

In Law 4342/2015 on energy efficiency improvement, energy audit is defined exactly as in Directive 2012/27/EU as follows:

“Energy audit” means the systematic process for acquiring sufficient knowledge of the existing set of energy consumption characteristics of a building or a group of buildings, an industrial or commercial activity or installation, as well as private or public services, which identifies and quantifies the cost-effective energy-saving potential, and producing a results report.

The main objective of the energy audit is to identify and prioritize energy saving interventions based on the criteria of energy and economic efficiency. Often, the scope and process of energy control is extended to cover energy savings verification issues that occur after energy saving measures are taken.

This Guide defines the Procedures, Requirements and Directions (RIS) of energy audits in the premises and premises of an industrial or building complex or transport. Both the GOK's summoned brief energy audit and the extensive audit are covered. Energy auditing processes are an integral part of the procedures and requirements for energy management and energy saving studies (technical and economic investment studies).

Minimum Compliance Criteria for Energy Audits

Law No 4342/2015 harmonized the new EU Energy Efficiency Directive (EED), which replaced the ESD Directive (2006/32 / EU), in Greek law. Energy audits should meet the minimum criteria set out in Annex VI of the Law. They are carried out on the basis of the European standards of the EN 16247 series of energy audits, as they apply.

Energy audits are based on the following guidelines:

(a) they are based on updated, measurable, traceable functional data on energy consumption and (for electricity) on load characteristics,

(b) include a detailed overview of the energy consumption characteristics of a building or group of buildings, an industrial activity or an installation, including transport,

(c) based where possible on Life Cycle Cost Analysis (LCCA). They are no longer relying on Simple Payback Periods (SPP). In this way, account is taken of:

  • long-term savings,
  • the residual values of long-term investments
  • and revaluation rates

(d) they are proportionate and sufficiently representative to give a reliable picture of the overall energy efficiency. They aim to reliably identify the most important opportunities for improvement. Energy audits allow for detailed and validated calculations of the proposed measures. They provide clear information on the potential for energy savings.

The new Law 4342/2015 has unified the process of energy audits in industry and buildings. This includes the transport sector. It also clearly states that energy audits are based on actual energy consumption. Contrary to the use of computational estimates for its consumption as initially defined in the Building Energy Performance Regulation.

Guide to Cost Benefit Analysis

Guide to Cost-Benefit Analysis of Investment Projects

EU Economic appraisal tool for Cohesion Policy 2014-2020

EU cohesion policy aims to achieve growth and jobs. This objective is in line with the objectives and objectives contained in the Europe 2020 Strategy. The selection of best quality projects offering the best value for money and having a significant impact on employment and growth is an essential element of the overall European Union strategy.

In this context, the Cost Benefit Analysis Guide (CBA) is a key decision-making tool. It is particularly applicable to the co-financing of major projects included in the operational programs of the European Union. Implementing bodies are responsible for funding. Including the European Regional Development Fund (ERDF) and the Cohesion Fund.

The Cost Benefit Analysis Guide (CBA) is an analytical tool used to evaluate an investment decision. The objective is to assess the change in the objectives pursued and to contribute to the objectives of EU cohesion policy. It aims at a more efficient allocation of resources, demonstrating the possibility and existence of alternatives. The Guide also includes legal requirements and its scope in the evaluation of investment projects within the EU. It complies with EU regulations and other European Commission documents.
