Energy Efficiency Upgrade | Engineer Company Liakos Consulting & Construction

Energy Upgrade

We shouldn’t worry only about which the cheapest fuel to consume is, but primarily how our buildings will consume less.

  • Energy efficiency upgrade is the only solution which ensure heating and cooling energy saving and improvement of thermal comfort conditions inside the building.
  • Changing the heating or cooling system is not sufficient to solve the problem of energy saving and is effective as long as the new fuels are maintained at the current low prices.
  • The best results in energy saving are achieved by combining building envelope improvements and Renewable Energy Systems installation (solar thermal, heat pumps, photovoltaics).

Energy InspectionOur company carries out the energy inspection of your building and issues the Energy Performance Certificate (EPC), which is essential whenever a property is build, sold or rented. An EPC gives a property an energy efficiency rating from A (most efficient) to G (least efficient). It is valid for 10 years and is required for properties with over 50sq.m. of total useful floor space.

Please contact us and an energy inspector will soon come to inspect your building for the EPC issuance at very competitive prices.

Furthermore, we offer consulting and implementation services for every kind of intervention, required for energy upgrade and maximum energy savings in the building. We strive to complete the necessary works in the shortest time and at the lowest cost possible, causing the least inconvenience for the residents.
