Energy Saving and Efficiency

The energy saving, it is got by the appropriate use of energy which is consumed by buildings, using energy responsibly and reducing consumption on a significatively way, and even using clean and renewable engery sources, for that, buildings must has some characteristics which correspond to that objetive.

Characteristics:
- A limited energy demand.
- Well done the termal instalations.
- Low consumption light instalation, which means, efficiency.


How awnings influence on energy efficiency.
The installation of awnings is considered as an improvement of energy efficiency on houses, restaurantes, or buildings, awnings are sun protection systems and improve the energy efficiency by a very little cost. Those allows you to filtering solar radiation in hours when sunligth is direct avoiding the overheating of the building face but light comes in when it is necessary.


Regulations:

Energetic certifications requirements of buildings set it down in Directive 2002/91 / EC of the European Parliament and of the Council on 16th December 2002, transposed in Royal statment 47/2007 on 19th January, which produced a basic procedure for the certification of energy efficiency of new buildings constructons.

Subsequently, the Directive 2002/91 / EC of the European Parliament and of the Council of 16th December 2002, has been modified by the Directive 2010/31 / EU of the European Parliament and of the Council of 19th May 2010 about the energy performance of buildings, a fact that has forced again to 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 5th 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.


General registry of recognized documents necessary for certification of energy efficiency.

According to Article 3 of the Royal Statment, this registry is created in order to facilitate the basec procedure compliance. It belows to the Energy Secretary of the State, Ministry of Industry, Energy and Tourism, being public and informative.

Advisory Committee for the certification of energy efficiency of buildings.

Article 15 thereof, the permanence of the Advisory Committee for the certification of energy efficiency as a body edficios permanent organically depends on the Ministry of Energy, Ministry of Industry, Energy and Tourism is established. Its mission is to advise the relevant ministries on matters related to energy certification.

Label of energy efficiency on a building.

Obtaining the certificate of energetic eficience will allows you to use this label, while the period of validity of it, the contents corresponding to the energy efficiency label recognized document, available from the General Register are collected.

The label will be included in any offer, promotion and advertising to the sale or lease of the building or a building unit. It should always appear on the label, clearly and unequivocally, if this label is refered to the certificate of energy efficiency of the project or the finished building.

General register of documents recognized for the certification of energy efficiency.

According to Article 3 of the Royal Decree, this record is created in order to facilitate compliance with this basic procedure. It is attached to the Ministry of Energy, Ministry of Industry, Energy and Tourism, taking public and informative.

In that register are those documents they have received all the Ministries of Industry, Energy and Tourism and Promotion recognition and has been structured according to the application corresponding to each recognized document.

ENERGY SAVINGS & ENERGY EFFICIENCY

Blind – Awnings and energy saving

Referring to the blind and awnings that according to the standard UNE-EN 14501/06 are designated as sun protection devices sector.

They specify and classifies into the following categories according to their characteristics:

First classification: Thermal Control

Please note:
– The solar factor, transmitted energy.

– Heat transfering.

– Direct sunlight, transmitted light.

Second classification: Visual comfort

– Opacity

– Privacy

– Use of daylight

– Glare.

– Color Reproduction.

– Visual contact with the outside.

Thermal comfort and sun protection devices are directly related because the latter affect the amount of external heat that reaches the building.

And refers to the above categories to test devices and determine how they influence the ability to save energy on housing.
