HELESCO SA, being a registered auditor approved by the Hellenic Ministry of Environment and Energy (Reg. No. 1360), is authorized to conduct any energy audit.

To date, HELESCO SA has conducted more than 40 energy audits for leading companies in the banking, retail, service and industry sectors.

Energy Management

The Energy Management System (EMS) is used to continuously and systematically determine energy flows and identify specific interventions that need to be taken to improve energy efficiency.

The EMS can be applied to small and large final energy consumers including energy-intensive industries, SMEs, public sector organizations, tertiary sector buildings and companies (e.g. department store chains), etc. Recognizing the need to promote energy management, HELESCO SA offers the following services:

  • Energy audit of installations (collection of primary energy data and operating conditions, measurements with HELESCO’s special equipment).
  • Energy report (evaluation of the current situation, identification of points that call for improvement, proposal for the implementation of an energy management system).
  • Thorough examination of the company’s facilities, to identify and inform the management of further intervention options at the levels of systems, subsystems, or individual equipment.
  • Design and installation of energy monitoring and management system.
  • Monitoring the operation and energy consumption of installations.
  • Analysis of the recorded results, determination of energy indicators, determination of energy consumption reference levels, and drafting of an energy efficiency improvement programme.
  • Support for company certification according to the ISO 50001 standard.

Project reference

Energy Efficient heating and cooling in Offices

Energy Performance Contracting

The project concerns the implementation of control measures to improve energy efficiency for heating and cooling. The project was 100% funded by helesco A.E. and is implemented under an Energy Performance Contract in accordance with the quality criteria of the European QualitEE project under the supervision of CRES. An annual energy saving of 20% is achieved as regards heating and 8% as regards cooling (4,754 l of heating oil and 147,789kWh of electricity consumption before the interventions, and 3807 l of 136.906kWh of electricity afterwards).
