Exploiting the Potential of Integrated Public Building Data: Energy Performance Assessment of the Building Stock in a Case Study in Northern Italy

Abstract

Smart management of urban built environment relies on the availability of data supporting sound policy making and guiding city renovation processes toward more sustainable and performant models. Nevertheless, public managers are unlikely to have comprehensive information on the existing building stock. In addition, tools providing effective insights on potential costs and benefits of retrofit strategies at city/district scale are hardly available. This article describes how data related to existing buildings may be effectively combined together into a so-called Building Information System, and discusses the advantages and shortcomings related to this process. At the same time, the implementation on a real case study in northern Italy demonstrates how the effort due to data harmonization and integration is able to foster applications to support policy makers in the management of the built environment and in the definition of urban sustainability strategies. Building data were harmonized according to the requirements of the international open standard CityGML, therefore facilitating the exchange of building information. The whole project was carried out while considering the characteristics of data sources that are available for each public body in Italy and, as a consequence, it may be replicated to other Italian municipalities.

The Project to Complete the Regional Topographic Geodatabase in Lombardy, Italy

“…This opens the way to adopt the DBTR data as hub for connecting several types of geocoded information which may characterize some important classes of objects. For example, the integration of cadastral data (land and buildings -see Guzzetti and Pasquinelli, 2012), the access to public utility and energy consumption data (Pasquinelli et al, 2019), the data exchange with BIM (Building Information Modelling -see Garramone et al, 2020), among others. Last comments are related to organization and development of this project.…”

Energy Retrofit in European Building Portfolios: A Review of Five Key Aspects

“…Article [6, [84][85][86][87][88][89][90][91] Conference paper [92][93][94][95][96][97][98][99][100][101][102][103][104][105] [ [106][107][108][109][110][111][112] Review [113][114][115][116][117] After every publication in Table 1 was accurately analyzed, it demonstrates that the methodologies employed are rather heterogeneous, and sometimes they even show conflicting results. Hardly any research proposes a comprehensive study, covering all the aspects that should be considered, from the early audits to the final decision-making processes.…”

“…The study in [93], for example, analyzed the application of a BIM procedure to produce and extract data during the energy retrofit and future management of a school building stock in Melzo, Northern Italy. The use of a Building Information System (BIS), instead, was discussed in [90] to demonstrate how a ready-to-use information package is very significant for the pursuit of collective interests in energy savings, supporting policy makers and defining urban sustainability strategies. The BIS process was tested by the authors on the Gavardo Municipality in Italy.…”

Raise the Roof: Towards Generating Lod2 Models Without Aerial Surveys Using Machine Learning

“…For example, Weiler et al (2019) argue that having an LoD2 is essential for rooftop photovoltaic estimations (and in a broader context for energy estimations, e.g. for more accurate calculations of the thermal boundaries of a building (Pasquinelli et al, 2019)). Similar conclusions are reached by Peronato et al (2016).…”
