2006 The energy efficiency standards required to install energy solar in new buildings as well as to register their energy rating
Under IDEA - Institute for Energy Diversification and Saving of Energy - the requirements for new buildings with energy efficiency will be applicable from January 2006 in accordance with the policy set by the Energy Efficiency in Buildings EU. This directive adopted in 2002 had three objectives: reducing energy consumption, improve performance and enhance systems used for solar thermal and photovoltaic. Following this directive, adopted in Spain by the end of 2005 a new regulation with three lines Action:
1. Technical Building Code: addition to limiting energy demand and improve the performance of the systems raises the incorporation of solar thermal for hot water heating, solar photovoltaic and large consumer centers.
As an example, it is mandatory to incorporate photovoltaic panels at:
- hotels and hospitals (> 100 seats or beds)
- multi shop centers (> 3,000 m2)
- offices (> 4,000 m2)
- Hypermarkets (> 5,000 m2 )
2. Regulation of Thermal Installations in Buildings: Establishes minimum requirements to meet and plan revisions for boilers and air conditioning.
3. Energy Certification of Buildings: provide for classification of buildings according to their energy efficiency by establishing a minimum allowable and giving the buyer a benchmark for housing from the point of view of energy consumption. Besides
Energy Certification, Technical Code of Building, the White Paper on Sustainability in Building or the English System of building environmental assessment, which still works, can be turned upside down on real estate, reticent to changes in most cases, and which will require that housing bioclimatic as possible.
The reasons are obvious change is estimated that green homes can save up to 60% in daily energy consumption, as Jesus says Ascunde, general director of Planning and Housing of Navarre, and reduce energy consumption in buildings is an imperative of the EU.
Today, 34 municipalities and autonomous region, the Canary Islands have control and respect and in another dozen are pending. In all there are specific support to the installation of solar thermal systems. Among the municipalities with ordinances passed, the capitals of Barcelona, \u200b\u200bMadrid, Sevilla, Granada, Burgos, Pamplona, \u200b\u200bCeuta and, recently, Valencia. Rota also
, Sant Cugat del Vallés or Hospitalet de Llobregat. In Castilla-La Mancha is in progress in Guadalajara, and Albacete Azuqueca de Henares. In Galicia, is pending in several cities with special effort to Vigo and Santiago. La Coruña is implementing initiatives such as the widespread anecdotal solar meter, but nothing definite as to the ordinances in 2006.
The pioneering eco-city in Spain
Valdespartera. Approximately 420 euros each household will spend years of clean energy, says Ramon Betrán, head of planning of the City of Zaragoza. 60% saving of energy is made possible by glass galleries that act as greenhouses. In water, the savings will come from the separation of water and rainwater collection. This project of 9,687 homes (300 free) includes solar panels for hot water.
Sarriguren. 5,017 housing units housing the Sarriguren ecocity whose energy savings will reach 60% and the main measures are the direct solar collection, reuse of greywater and rainwater for irrigation and orientation. The project, completed in 2007, includes solar panels and photovoltaic, wind energy and biomass. The Government of Navarra has demanded and energy certification.
Trinitat nova. Ecocity Included in the project along with seven other European cities, Nova Trinitat project is driven by the Government of Catalonia, Barcelona City Council and local pressure. With the advice of consultants Aiguasol GEA 21 and whose criteria have been passive solar design, water separate network and a centralized system for cogeneration and solar panels. Consists of 3,500 homes.
