Saving energy it is given by the appropriate use of energy is consumed in buildings, using energy responsibly and reducing consumption signifiable way, and in turn exploiting the clean and renewable sources of energy, this building must possess characteristics which correspond to the construction and maintenance.
- A limited energy demand
- Heat plants perform well.
- Facilities that are bright energy concumo low, that is efficient.
As awnings influence energy efficiency
The installation of awnings is considered an improvement in energy efficiency of housing, and awnings are sun protection systems and improve the energy efficiency of the windows with very little cost. Allow filtering solar radiation in the hours of direct sunlight to avoid overheating of the facade and allow light into the house when necessary.
The requirements for the energy certification of buildings set in Directive 2002/91 / EC of the European Parliament and of the Council of 16 December 2002, transposed in Royal Decree 47/2007 of 19 January, by which a basic procedure for the certification of energy efficiency of new buildings was approved.
Subsequently, Directive 2002/91 / EC of the European Parliament and of the Council of 16 December 2002, has been amended by Directive 2010/31 / EU of the European Parliament and of the Council of 19 May 2010 on the energy performance of buildings, a fact that has forced again transpose into Spanish law the changes made with respect to the amended directive.
While this transposition could be done through a new provision to amend the Royal Decree 47/2007 of January 19, and at the same time to complete the transposition contemplating existing buildings, it seems appropriate to be performed by a single provision recasting it valid the standard of 2007, the repeal and complete, incorporating the innovations of the new directive and broaden its scope to all buildings, including existing.
Accordingly, by this Royal Decree partially it transposes Directive 2010/31 / EU of the European Parliament and of the Council of 19 May 2010, concerning the certification of energy efficiency of buildings, merging the Royal Decree 47/2007 , on January 19, with the addition of basic procedure for certifying the energy performance of existing buildings.
This Royal Decree 235/2013, of 5 April, approving the basic procedure for certifying the energy efficiency of buildings is approved, entered into force on the day following its publication in the Official Gazette No. 89 (13 / 04/2013) is voluntary implementation until 1 June 2013. from that moment, the presentation or making available to the buyers or tenants of the energy performance certificate of all or part of a building as appropriate, be required for the sale or lease contracts concluded after that date.
