Desde el punto de vista térmico, el uso de materiales multifuncionales e innovadores en las superficies urbanas puede proporcionar mejoras radicales y reducir el efecto de Isla de Calor Urbana. En la simulación energética de edificios se ha prestado poca atención a las interacciones, no despreciables, entre la envolvente exterior de los edificios, la demanda energética y su impacto en el microclima urbano. Las herramientas actuales de simulación de edificios tienen una capacidad limitada para evaluar estas interrelaciones. Por estas razones, es necesario crear flujos de trabajo basados en simulaciones ad-hoc capaces de evaluar la influencia de los materiales y sus impactos en ambientes exteriores e interiores. Este artículo muestra la estrategia de simulación que se utilizará en un proyecto de investigación nacional cuyo objetivo es validar la viabilidad del uso de materiales urbanos optimizados, mediante simulación. Para ello se utilizará un innovador flujo de trabajo racionalizado basado en la herramienta Grasshopper.
Abstract
From a thermal point of view, the use of multifunctional and innovative materials in urban surfaces can provide radical improvements and reduce the Urban Heat Island effect. In building energy simulation, little attention has been paid to the non-negligible interactions between the external building envelope, energy demand and its impact on the urban microclimate. Current building simulation tools are limited in their ability to assess these interrelationships. For these reasons, it is necessary to create workflows based on ad-hoc simulations capable of assessing the influence of materials and their impacts on outdoor and indoor environments. This article shows the simulation strategy to be used in a national research project aiming to validate the feasibility of using optimised urban materials through simulation. An innovative streamlined workflow based on the Grasshopper tool will be used for this purpose.
