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.

Directive 2009/125/EC Definition of eco-design requirements

DIRECTIVE 2009/125 / EC laying down ecodesign requirements for energy products

Directive 2009/125/EC on the setting of ecodesign requirements concerns the establishment of a framework for setting ecodesign requirements for energy-related products.

Directive 2009/125/EC sets out a framework for setting ecodesign requirements. It refers to products that consume energy.

Application feasibility

Energy-related products represent a large proportion of the consumption of natural resources and energy in the Community. They also have some other significant environmental impacts. For the vast majority of product categories available on the Community market, very different degrees of environmental impact can be noted. Although they may exhibit similar operational performance.

The continuous improvement of the overall environmental footprint of these products should be encouraged.

An instrument for this purpose is to identify the main sources of negative environmental impacts and to avoid the transfer of pollution. This applies provided that this improvement does not entail excessive costs.

Many energy-related products have significant potential for improvement in reducing environmental impacts. The goal is to achieve energy savings through better planning. The latter also leads businesses and end users to save financial resources. In addition to products that use, produce, transfer or measure energy, certain energy-related products, including:

  • of products used in construction such as windows,
  • insulating materials, or
  • some products using water such as shower heads or faucets,

They could also make significant savings in their use.

Eco-design of products is a vital factor in the Community strategy. It also leads to the implementation of an integrated product policy. As a precautionary approach, aimed at optimizing the environmental performance of products. At the same time, their functional properties are maintained and new real opportunities are offered to manufacturers, consumers and society as a whole.

Alternative options

More efficient end-use of electricity is one of the most important options for improving energy efficiency. Its contribution is considered to be essential to the achievement of the Community's greenhouse gas emissions targets. Electricity demand is the fastest growing end-use energy category. It is expected to increase within the next 20 to 30 years if no policy measures are taken to reverse this trend.

According to the European Climate Change Program presented by the Commission, a significant reduction in energy consumption is possible. Climate change is one of the priorities of the Sixth Community Environment Action Program. Energy saving is the most cost-effective way of enhancing security of supply and reducing dependence on imports.


Purpose of the Directive

Directive 2009/125/EC establishes a framework for the establishment of Community eco-design requirements. It relates to energy-related products in order to ensure the free movement of these products in the internal market. The Directive provides for the introduction of requirements that energy-related products have to meet. These requirements are covered by implementing measures in order to make the products available on the market and / or put into service. It contributes to sustainable development by increasing energy efficiency and the level of environmental protection, while at the same time increasing security of energy supply.
