Over the past few decades, digital tools have become indispensable in the field of architecture. The complex design tasks that make up architectural design methods benefit from utilizing advanced simulation software and, consequently, design solutions have become more nature-adapted and site-specific. Computer simulations and performance-oriented design enable us to address global challenges, such as climate change, in the preliminary conceptual design phase. In this paper, an innovative architectural design method is introduced. This method consists of the following: (1) an analysis of the local microclimate, specifically the wind situation; (2) the parametric shape generation of the airport terminal incorporating wind as a form-finding factor; (3) Computational Fluid Dynamics (CFD) analysis; and (4) wind-performance studies of various shapes and designs. A combination of programs, such as Rhinoceros (Rhino), and open-source plug-ins, such as Grasshopper and Swift, along with the post-processing software Paraview, are utilized for the wind-performance evaluation of a case study airport terminal in Reykjavik, Iceland. The objective of this wind-performance evaluation is to enhance the local wind situation and, by employing the proposed architectural shape, to regulate the wind pattern to find the optimal wind flow around the designed building. By utilizing the aforementioned software, or other open-source software, the proposed method can be easily integrated into regular architectural practice.

This paper presents the analysis and performance evaluation of an embedded prototype to control the access of people to companies or institutions by using short range wireless technologies, like NFC and RFID. The developed system proposes a hybrid identification method between MIFARE cards and smartphones with Android operating system. It integrates a web platform in charge of the processing of the system data and increase the use of the technology through services where the gathering of people and objects register and authentication is required. With this proposal, we seek to optimize the time in the identification transactions and improve the security in places where the manual access is carried out. This work is an answer to the need of an adequate management of the access control of the Technological Faculty personnel in the Universidad Distrital Francisco José de Caldas in Bogotá: the chosen scenario for testing our proposal.
