Use of BIM and Smart Monitoring for buildings’ Indoor Comfort Control

Abstract

Building information modeling (BIM) is the geometric way to present a life cycle construction project including geographic information. Recently, the Internet of Things (IoT) has been progressively used smart buildings in order to enhance living comfort, work productivity and entertainment. However, studies addressing the combination of these two technologies (BIM and IoT) focused on the automatic diffusion of data through sensors to BIM models [1]. Based on American College of Occupational and Environmental Medicine (ACOEM) a great portion of our time is spend inside buildings, in our offices, homes, schools, health care facilities, or in other private or public buildings. Hence the necessity to improve the basic human right to live in a healthy, safe and comfort environment is vital. This paper presents the use of BIM to support complex decisions concerning comfort conditions in buildings. This use is illustrated through a case study concerning a building of the AUST campus in Beirut.

IoT Open-Source Architecture for the Maintenance of Building Facilities

“…The integration of an FC monitoring system into the BIM model would improve the building's maintenance plan by helping the facility managers to inspect the monitored building environments inside the 3D model. Thus, facility managers can profit from the proposed framework to resolve maintenance problems in the following aspects: The study conducted in this paper aims to fill the gaps of the following researches: limited number of sensors [23], an absence of automation [24], and lack of data acquisition system [25]. The final results of the fully automated framework composed of IoT sensors, dashboard, IoT and BIM integrated application, and implemented preventive maintenance methodology of the building facilities on the server prove the proposed framework's applicability.…”

“…Similar research has already been introduced [23][24][25], where some authors [23] represent automated IoT and BIM-based alert systems for comfort monitoring in buildings. They used humidity and temperature sensors to detect discomfort in rooms, whereas other authors [26] integrated IoT sensor data (temperature, illuminance and power consumption) to monitor indoor conditions of the buildings.…”

Interoperability of Digital Tools for the Monitoring and Control of Construction Projects

“…It is common for several of these methods, such as laser scanning, photogrammetry and videogrammetry, to generate three-dimensional point clouds, which allow for the construction of as-built models that give the opportunity to identify the progress at a construction site from various angles and, thus, evaluate the current progress of a project. Among these methods, photogrammetry is the most economical and efficient technique for obtaining a 3D point cloud, which is necessary for progress documentation [53]. Additionally, data fusion using overlapping time frames or overlapping location information from multiple sources is possible by matching the same timestamps or locations.…”

Algoritmo para automatizar el detallado de acero de refuerzo en modelos BIM mediante Dynamo

“…Así mismo, Dynamo está siendo utilizado por los usuarios https://doi.org/10.37787/pakamuros-unj.v11i1.359 _______________________________________________________________________________________ como un plugin, o complemento, para Revit y permite generar geometrías matemáticas complejas mediante bloques de código y parámetros, permitiendo el cambio automático de estos parámetros desde el software BIM (Dzwierzynska & Lechwar, 2022;Kensek, 2014). Esto quiere decir que, en lugar de digitar un código, la interacción entre los usuarios y Dynamo, genera una secuencia de comandos manipulando elementos gráficos llamados nodos (Wehbe & Shahrour, 2019). Donde, cada nodo puede tener un número de "puertos", que permiten la comunicación entre ellos a través de "conectores".…”
