Energy Saving in Buildings

The objective of energy saving in buildings is to achieve desirable levels of comfort and assure hygiene and safety levels with minimal required energy consumption. The same energy saving objective applies to outdoor applications.  In production processes, energy saving is required to ensure the quality and quantity of production with minimal energy consumption.

Applications

Energy saving investments apply mainly to the following:

  • Residential sector: replacement of door and window frames and heating systems;
  • Tertiary sector buildings: installation of highly efficient heating, cooling and air-conditioning systems;
  • Outdoor areas: installation of highly efficient lighting appliances and bulbs;
  • Production procedure: use of discarded heat, heat and power cogeneration systems, replacement of machines with new, more efficient machines.

Advantages - Environmental Benefits

The advantages of energy saving solutions are:

  • Relatively stable performance;
  • comparatively low maintenance cost and
  • the fact that they increase the value of real estate.

Moreover, the following are achieved through saving applications:

  • reduction of greenhouse gas emissions and
  • reduction of the environmental footprint of homes, businesses or industries.

Institutional Framework

The legal framework covering construction sector is particularly voluminous. As concerns energy saving in buildings, Law 3661/2008, as amended by article 10 of Law 3851/2010, is considered the most important. This law came into force on 1st October 2010 incorporating the concept of integrated energy planning in buildings, while a requirement for the classification of energy consumption in buildings was instituted. Moreover, the obligation to issue Energy Efficiency Certificates for buildings was instituted; this requirement applies to both new buildings and the radical renovation of existing ones, and also for the sale/purchase and renting of buildings.
