ENERGY PERFORMANCE CERTIFICATE (EPC)
The Energy Performance Certificate (EPC), as defined in Directive 2010/31/EU of the European Parliament and of the Council and in Law No. 4122/2013 (Greek Government Gazette 42/19-02-2013), is a document licensed by the Ministry of Environment & Energy, which informs the user/owner about a building's energy performance.
The Energy Performance Certificate classifies the buildings into energy categories in a scale from A to G, where category A represents the buildings or the building units with the highest energy performance.
The Energy Performance Certificate is issued by the energy auditor, who has been registered into Buildingrcert, the energy auditors’ special register, and is issued along with recommendations for energy saving measures, with the purpose of reducing the operating & energy costs of a building.
Energy audits are an important means of diagnosing the energy situation of the existing buildings, of classifying them into an energy category and exploring the possibilities of improving their energy situation. The classification of the building into an energy category is made based on the ratio of the building’s consumption to the consumption of the reference building.
Issuing an EPC is required for all the buildings with a total surface area of above 50m2 that cover basic uses (housing, both permanent housing and cottages, offices, commercial uses, assemblies, education, temporary residence, health and social care, etc.), as follows:
New and radically renovated:
After the construction of each new or radically renovated building is completed
for each sale-purchase of a single building and sale-purchase of a part of a building (e.g. apartment)
for each rental of a single house and rental of a part of a house (e.g. apartment), used as residence and as offices
THE ISO 50001:2011 STANDARD
According to the EU Directives, the Member States must commit themselves to a gradual reduction of energy consumption.
The ISO 50001:2011 standard on Energy Management is the most recognized energy tool leading to energy consumption reduction practices and contributes to economic and energy benefits for the business.
The objective of the implementation of ISO 50001:2011 is the establishment of the procedures required to lead to the best energy performance.
The standard is based on the methodology of the Deming approach “Plan - Do - Check - Act”. Except from the systemic requirements (documentation check, personnel training, monitoring of corrective and preventive actions, audit and review), it also requires mainly the following:
establishment of an appropriate energy policy
identification of the energy aspects / needs and detection of opportunities for energy improvement
identification of legal and other requirements regarding the energy aspects of the organization
identification of specific objective aims and goals regarding efficient energy use, the realization of which is completed with the implementation of systematic energy management programs
The establishment of an organizational structure for an effective implementation of an Energy Management System.
Benefits from the implementation and certification of an energy management system:
Immediate energy saving
Reduction of the operating and production cost
Reduction of greenhouse gas emissions
Improvement of the ecological & energy footprint
Improvement of the company profile
Compliance with legislative requirements
Improvement of the energy & environmental consciousness of the personnel
Law No. 4342/2015 (Greek Government Gazette 143A/9-11-2015)
According to Law No. 4342/2015 (Greek Government Gazette 143A/9-11-2015), that is the compliance of the Greek law with the Directive 2012/27/EU on the energy performance, the businesses that are not micro to medium enterprises (businesses with at least 250 employees, the turnover of which exceeds EUR 50 million or the annual balance of which exceeds EUR 43 million) must undergo an energy audit carried out in an independent and cost-effective manner by energy auditors within 1 year from the entry into force of the Law and, after that, they must undergo a new audit within 4 years at the latest from the date the previous energy audit was carried out.
However, the businesses that are not micro to medium enterprises and implement an energy or environmental management system certified by an independent body, in accordance with the relevant European or international standards (e.g. ISO 50001), are exempt from the above audit obligation by energy auditors, on condition that this management system includes an energy audit based on the minimum criteria as defined in Annex VI of the Law.
