Model de simulació per l'optimització en l'edificació atenent la normativa de sostenibilitat (impactes ambientals, econòmics i socials)

In the last years, international and national policies have been developed in order to encourage the improvement of energy efficiency. They have also been developed in order to reduce the environmental, economic and social impacts due to economic and industrial activity. It is necessary to highlight the European guidelines 210/31 / UE and 2012/27 / UE, in relation to buildings’ energy efficiency, or the strategic policies raised in the European Council, known as 20-20-20 (for a reduction of emissions of greenhouse gases, energy savings and for a proposal of increase in the generation of energy through renewable sources) which has generated an important framework to move towards a more sustainable environment, jointly with the international building sustainability regulation CEN/ TC 350, transposed nationally by the working group AEN / CTN 198. As an answer to the actual needs and to the vacuum to evaluate systems, responding to all the policies previously mentioned, a simulation model called BuildingSim has been developed, which is based in standard language, formal graphic and complete SDL (Specification and Description Language), regulated by the ITU-T. This model is able to respond to the sustainability regulation (environmental, economic and social impacts) analyzing the selected case study depending on its complete life cycle (from the design, going through the building process, usage/maintenance and deconstruction), taking in to account the reuse and the energy compensation processes. The model is able to use different thermodynamic calculation engines, which are international known and validated in multiple studies and projects in a co-simulation environment. The simulated scenarios are based in BIM models (Building Information Modelling) that under the use of integrated algorithms optimization or brute force, allow us to find the optimal curve to locate the best options for designing purposes, in order to reduce associated impacts. According to the initial approach, the model is easy to be extended for different work environments, without needing to have experience is programming systems. It is understandable for all the team members, because it integrates a holistic vision which facilitates validation and verification of the process. The model doesn’t need specific implementation, and verification is direct, because the system’s architecture and the own programming model are the same. The model can be applied in technological development and in re
