Web-Based Management of Public Buildings: A Workflow Based on Integration of BIM and IoT Sensors with a Web–GIS Portal

Abstract

In this paper, we present the final results from the research project “Urban Abacus of Building Energy Performances (Abaco Urbano Energeticodegli Edifci–AUREE)” aimed at supporting the renovation process and energy efficiency enhancement of urban building stocks. The crux of the AUREE project is a Web–GIS GeoBlog portal with customized semantic dashboards aimed at sharing information on an urban built environment and promoting the participation of local stakeholders in its improvement. As the latest development of this research, a workflow that integrates the AUREE portal with BIM authoring and an open-source IoT platform is implemented and applied to an experimental case study concerning a public building in Carbonia (Italy). The headquarters of the Sotacarbo Sustainable Energy Research Center was selected as the case study. The presented results proved that it was possible to create a valid open system, which was accessible to both specialist and unskilled users, and aimed at guiding, through a progressive knowledge deepening, common end-users toward proper conscious “energy behaviors” as well as public administrations and decision-makers toward sustainable facility management. Later, the proposed open system could also be suitable to be used as an effective tool to support the rising “energy communities”.

A GIS-Based Top-Down Approach to Support Energy Retrofitting for Smart Urban Neighborhoods

“…Using a BIM-GIS approach has the power to combine multiple levels of data in a single model to support and visualize energy retrofitting [54]. In addition, the BIM-GIS model can be presented to policy makers and the other stakeholders in the retrofitting process using web-based systems [49]. Future works should build on the works in this study and enhance the GIS model with BIM, particularly for Saudi Arabia and the region.…”

“…The study was able to identify the most appropriate EEM for building types. Another study in Carbonia, Italy presented a webbased GIS model with the aim of sharing information of the built environment to promote the participation of stakeholders in the decision-making process [49]. They presented a case study of a public building that successfully adopts the model for sustainable facility management.…”

“…The retrofit measures recommended in this study for Riyadh also reciprocate the EEMs presented in other studies in the country for energy retrofitting. According to several studies with a bottom-up approach, energy retrofitting has the potential to significantly reduce energy demand across a range of buildings including residential [18,21,[50][51][52], academic [53], and office buildings [49,54]. A study, for example, demonstrated measures that can cut energy use by up to 60% in residential buildings.…”

Based on BIM intelligent technology and IPD collaborative management model applied to characteristic towns with PPP mode

“…(3) Congiu et al (2023) introduces a web-based management approach for public buildings that integrates BIM, IoT sensors, and a Web-GIS portal. This approach can improve building efficiency, reduce maintenance costs, and enhance public safety by enabling real-time monitoring of building status and performance.…”

Geospatial Analysis in Web Browsers—Comparison Study on WebGIS Process-Based Applications

“…Analytical data processing can be performed in real time or based on individual user parameters (e.g., buffer distance, hot spot limit, attribute field selection, etc.) [5]. Geographic and geoinformatic analyses are now common practices in the desktop environment, and they are used routinely.…”
