Extending BIM for air quality monitoring

As we spend more than 90% of our time inside buildings, indoor environmental quality is a major concern for healthy living. Recent studies show that almost 80% of people in European countries and the United States suffer from SBS (Sick Building Syndrome), which affects physical health, productivity and psychological well-being. In this context, environmental quality monitoring provides stakeholders with crucial information about indoor living conditions, thus facilitating building management along its lifecycle, from design, construction and commissioning to usage, maintenance and end-of-life. However, currently available modelling tools for building management remain limited to static models and lack integration capacities to efficiently exploit environmental quality monitoring data. In order to overcome these limitations, we designed and implemented a generic software architecture that relies on accessible Building Information Model (BIM) attributes to add a dynamic layer that integrates environmental quality data coming from deployed sensors. Merging sensor data with BIM allows creation of a digital twin for the monitored building where live information about environmental quality enables evaluation through numerical simulation. Our solution allows accessing and displaying live sensor data, thus providing advanced functionality to the end-user and other systems in the building. In order to preserve genericity and separation of concerns, our solution stores sensor data in a separate database available through an application programming interface (API), which decouples BIM models from sensor data. Our proof-of-concept experiments were conducted with a cultural heritage building located in Bled, Slovenia. We demonstrated that it is possible to display live information regarding environmental quality (temperature, relative humidity, CO2, particle matter, light) using Revit as an example, thus enabling end-users to follow the conditions of their living environment and take appropriate measures to improve its quality.Pages 244-250

The role of architect in interdisciplinary collaborative design studios

Architectural design is a complex process involving different actors. While studying architecture, students usually work alone, and they do not have many opportunities to collaborate with other professions. Consequently, they end up lacking the knowledge regarding other professions, as well as regarding communic42ation and collaboration with other professionals. They become too proud of themselves, which eventually prevents them from engaging in active collaboration and accepting compromises. Furthermore, it is essential for their future professional careers that architects collaborate with other professions, adopt their ideas and requirements. Such collaboration is recommended from the early stages of the design process onwards. The main focus of this article is to determine the importance of interdisciplinary collaboration in architecture projects through the process of studying architecture, the role of the architect within this process, and the manner in which decisions are usually made within an interdisciplinary team. The following research is based on the AEC Global Teamwork Course, which took place during school years 2011/2012, 2012/2013 and 2013/2014, 2013 at Stanford University under the leadership of Prof. Dr. Renate Fruchter. Students from all around the world worked together on an architectural project from its initial stages. They met twice only: at the beginning and at the end of the project, otherwise they worked on a virtual basis, using different digital tools intended for long-distance interdisciplinary collaboration. There were three case studies examined for the purposes of this article in which the main focus was placed on architects, more specifically on the challenges and the problems they were facing, the knowledge architects gained through interdisciplinary collaboration, and lessons learned in such a course that could help them with their professional careers
