Eficiencia Energética


Since April 13, 2013 the Royal Decree 235/2013, of April 5, approving the basic procedure for the certification of energy efficiency of buildings, is in force in Spain.

For sale or rental contracts to be signed from June 1, 2013 in Spain, it is mandatory to submit or make available to buyers or tenants the energy efficiency certificate of the house, as appropriate, in order to make both the buyer or tenant and the owner aware of the energy characteristics of the property.

This certificate, in addition to the energy rating of the property, provides information about the improvements that can be made, regarding both insulations and systems, and the amortization period, according to the energy savings that can be achieved.

LEMBUS has qualified staff to develop energy certifications of any kind of property or building, with personalized attention and accurate result.
