First of all, let us provide a slight introduction for netsurfers. What is the Energy Certificate? It is an official technical document approved in Spain by the Ministry of Industry, Energy and Tourism, where the energy-efficient features of a building are described. It shows the calculations of annual energy consumption required for meeting the energy needs of a building under regular habitability conditions, including hot water production, heating, lighting, cooling and ventilation.

Once the certification process is fulfilled, an energy-efficient Certificate will be issued and an energy label will be assigned. This label will attribute a letter to the building, based on its features. The building energy rating is a rating on the overall energy efficiency of a building, and it is denoted on scale of seven letters, from A (most energy-efficient building, below 6.8kg CO2/m2 per year) to G (least energy-efficient building, above 70.9kg CO2/m2 per year).

In particular, it gathers the annual kilograms of CO2 divided by the square meters of the building or establishment.

But, what does the energy-efficient certificate include?

  1. The building identification
  2. The identification of the procedure that has been chosen for obtaining the building energy rating, pointing out:
    1. A description of the energy-efficient features of the building, such as thermal envelope, automatic doors, regular habitability and operational conditions, as well as other items required to obtain the score.
    2. An energy identification code at the time of the construction.
    3. A description of verifications, surveys and inspections carried out by the personnel certification body.
  3. The building energy efficiency rating expressed by the energy label.
  4. The document gathering the recommended measures by the certifying technician. Measures, such as the installation of automatic doors which permit to maintain the internal temperature stable.

We have to bear in mind that currently, the energy certificate is mandatory, so when selling or renting out a property, having a high score on its rating scale can be one influential factor regarding the buying decision process. In the case where owners do not have the certificate, they might be penalized with fines ranging from €300 to €60,000, according to the 235/2013 Royal Decree (Law of Spain).

The Ministry of Industry, Energy and Tourism has entrusted the Institute for Diversification and Saving of Energy (IDAE) to make available to the public computer software to provide energy efficiency ratings for existing buildings, applied fully in the domestic territory, as well as the development of a training and information plan for the affected sectors.

As far as we are concerned, in Manusa we believe that the role of our automatic doors is an essential part of energy control, because thanks to its action, expenses such as buildings climate control systems can be highly reduced, thus obtaining a better energy certification.
