RESUMEN: En este artículo se presentan dos nuevas herramientas web que permiten cuantificar el potencial de rehabilitación en edificios residenciales del Principado de Asturias. La mejora energética se ha calculado mediante una metodología de simulación que identifica los casos más representativos, analiza su comportamiento energético través del acoplamiento entre TRNSYS y GenOpt, y realiza un post-procesado para calcular los potenciales finales. Se han identificados dos categorías de viviendas: unifamiliares y bloques de cuatro, siete y diez plantas; dos configuraciones para las condiciones de contorno: aisladas y adosadas; cuatro normativas edificatorias y varios porcentajes de sombra en las ventanas. Los mayores potenciales de rehabilitación se obtienen para las viviendas unifamiliares más antiguas, disminuyendo a medida que aumentan los requisitos normativos. Los bloques de viviendas presentan similares patrones pero con porcentajes inferiores. Finalmente, las configuraciones aisladas alcanzan mayores potenciales frente a las adosadas.
ABSTRACT: This article presents two new web tools that allow quantifying the refurbishment potential in residential buildings in the Principado de Asturias. The energy savings have been calculated using a simulation methodology that identifies the most representative cases, analyzes their energy performance through the coupling between TRNSYS and GenOpt, and performs post-processing analyses to calculate the final potentials. Two categories of buildings have been identified: single-family and blocks of four, seven and ten floors; two configurations for boundary conditions: isolated and semi-detached or linear; four building regulations and various percentages of shade in windows. The greatest refurbishment potentials are obtained for older single-family dwellings, decreasing as regulatory requirements increase. Similar patterns are reached by blocks but with lower percentages. Finally, isolated configurations achieve higher potentials compared to semi-detached or linear configurations.
