The road to nearly zero energy buildings. Case of study: Spain. Comparison between CTE HE 2006 and 2013 in a simulated model

Abstract

Abstract.Achieving Nearly Zero-Energy Buildings (NZEBs) is a main goal for the European Union, in order to reduce energy consumption in the building sector. NZEB means a building that has a very high energy performance. Its energy requirements should be covered by renewable sources, produced on-site or nearby [1]. It could be possible if building were turned into a "small power generating station", or reducing consumption with passive building proposals. However, we think that it is worth looking for a balance between energy consumption and generation for every building, following this simple equation: Consumption = demand -generationThe European regulations have already begun to indicate deadlines to implement NZEB requirements in buildings. This study was performed by using a computer building model, including its geometry, building materials, usage profiles and installations. Thus, we could compare the characteristics of the different regulations, and we could evaluate the progress toward the NZEB concept.

“…En algunos casos, el respeto al medio ambiente se argumenta mediante la aparición de una creciente conciencia medioambiental asociada al desarrollo económico de los países. A modo de ejemplo, la hipótesis de la curva de Kuznets medioambiental (EKC por sus siglas en inglés) 3 , propone que la relación entre ingresos e impacto medioambiental tiene una forma de U invertida. El crecimiento económico, que en etapas iniciales de desarrollo genera un creciente impacto sobre el entorno, terminará generando una conciencia medioambiental a sus habitantes y proporcionando recursos para que se reduzca el impacto de su actividad económica.…”
