Special Issue "Energy Efficiency in Buildings: Both New and Rehabilitated"

Share this Post:

From Journal Energies

Buildings are one of the main causes of the emission of greenhouse gases in the world; in Europe, for example, they are responsible for more than 30% of emissions, or about 900 million tons of CO2 per year. Heating and air conditioning are mainly responsible for greenhouse gas emissions in buildings.


Based on the above, it is a current priority to reduce (or ideally eliminate) the waste of energy in buildings and at the same time supply the necessary energy through renewable sources. The first can be achieved by improving the construction methods, the materials used and the efficiency of the facilities and systems; the second can be achieved through the use of renewable energies (wind, solar, geothermal, etc.) in buildings. In any case, regardless of whether the energy used is renewable or not, the efficiency must always be taken into account: the most profitable and clean energy is that which is not necessary.


Most current buildings were built with poor energy efficiency criteria and even, depending on the country and the date of construction, with none. Therefore, regardless of whether construction regulations are becoming stricter, a huge challenge is the energy rehabilitation of existing buildings.


In this Special Issue, potential topics include but are not limited to the following:


  • Methodologies, processes, methods to design/build/rehabilitate minimum energy consumption buildings.
  • Efficient electric loads: ventilation, heating, air conditioning, lighting, domestic hot water, appliances, etc.
  • Facilities in buildings for minimum energy consumption.
  • Renewable energy applications in buildings.
  • Maintenance and management of buildings for minimum energy consumption.
  • Methods and systems of energy measurement and control in buildings.
  • Home automation for energy efficiency in buildings.
