A methodological approach for a home occupants centred web tool to support buildings energy retrofitting process

Abstract

This paper presents a methodological approach to develop a user-oriented web tool to support the early stage of the decision making process for energy retrofitting of residential real estates. The tool mixes a simple analytical Urban Building Energy Model (UBEM) to user-oriented feedback interfaces to simulate the retrofitting potential of the residential units. The AUREE tool will be based on a Web – GIS GeoBlog portal with customized interfaces aimed to share the knowledge on urban building heritage and promote participation of stakeholders of the urban community. There are many literature exempla of guidelines or quality protocols on the topic of energy efficiency specified to particular types of buildings or focused on a territorial area, but these are generally not integrated into a geographically based tool. Moreover, the AUREE methodology aims to set interfaces that could use the portal users’ feedback to update the content of the portal itself. After touch on the theoretical context, a summary of the AUREE project is presented, and then the paper focuses on the structures of algorithms and tools adopted on the residential users’ interfaces. The interface mixes the results of an engineering Urban Building Energy Model based on local archetypal approach and standard energy calculation (series UNI 11300 - TS), with participative data provided via user-interactive interfaces to obtain customized retrofitting scenarios and suggestions. At the end of the paper, the main critical aspects and the further step of the research project are pointed

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

“…The residential building section contains a spatial representation of the energy performance of the building heritage provided from an easy UBEM methodology [32] and aims to directly involve the occupants, Public Decision makers and companies by defining a shared knowledge framework. The building typologies section is a different representation of the same baseline information about residential heritage energy performances grouped by building typologies.…”

“…The portal is implemented with an Urban Building Energy Model (UBEM) [29][30][31] based on spatial open data, a typological survey of the built heritage, and a participative web framework, as extensively described in [32]. It represents the main tool on which the collection and sharing of data on the energy performance of the built heritage of the city of Carbonia are based.…”

“…This work focuses on content and procedures of the public building section, for more information on other sections some other papers have been published before [32][33][34].…”

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

“…The concept of the AUREE project is a web-GIS GeoBlog portal with customized interfaces aimed at sharing information on the urban built environment and promoting the participation of local stakeholders in its improvement. The methodological approach is specifically addressed to small and medium urban centers, and is characterized by low availability of basic data on buildings' energy performances [28][29][30]. The town of Carbonia is selected as a relevant case study.…”

“…The portal provides an urban building energy model (UBEM) [31][32][33] based on spatial open data, a typological survey of heritage buildings, and a participative web framework, as extensively described in [29]. The portal consists in a handy tool enabling the collection and sharing of data on the energy performances of heritage buildings in the city of Carbonia The developed methodology consists of an analysis and a representation protocol of the heritage building on a geographical basis, combined with a tool for communication and involvement of local actors [28][29][30].…”
