A BIM-GIS integrated pre-retrofit model for building data mapping

Abstract

Due to copyright restrictions, the access to the full text of this article is only available via subscription.In response to rising energy costs and the impetus to reduce environmental impacts, upgrading the large building stock that is responsible for 40% of the total energy consumption to maximum energy efficiency is becoming an important task. Despite the many benefits associated with retrofit projects, they are still only slowly being implemented because of the many challenges that exist. One of these challenges is optimizing the decision between renovation scenarios based on economic and environmental goals, which can be made possible with an accurate pre-retrofit model. The intention of this paper is to introduce a pre-retrofit model that efficiently obtains and integrates multiple forms of building data as a critical step to develop a comprehensive understanding of a building to be renovated. Opportunities for utilizing building information modeling (BIM) and geographical information systems (GIS) for retrofitting projects were explored through the study of a historical campus building. With the use of as-is geometric data and as-is data, building data maps were obtained. The next step of this study is to use the model to conduct scenarios comparison and optimize renovation decision based on economic and environmental goals.Joan & Irwin Jacobs Technion-Cornell Innovation Institute (JTCII) ; TÜBİTA

A Data Ecosystem for Data-Driven Thermal Energy Transition: Reflection on Current Practice and Suggestions for Re-Design

“…A fair share of the common challenges and barriers in the literature on big and open data in energy systems are also encountered in the current data ecosystem of the Dutch thermal energy system. For instance, recurring barriers, such as inconvenient data access, availability and retrievability, inadequate or poor data collections, and lacking data standards, as presented in leading works for open and big data in energy systems [29,37,[40][41][42], are confirmed by the interviewees in the present study. However, we also uncovered new barriers, such as distrust among citizens leading to poor willingness to share data, contradicting policy requirements and legislation, and the dispersed character of data over various platforms and owners.…”

“…Reis et al [36] provide an overview of recurring challenges and barriers in the application of open data and open data portals worldwide, based on a systemic literature review. The following is an overview of these challenges, complemented with challenges from other work: Inconvenient data access, availability, and findability; clarity of data purpose; inadequate or poor data collection; data license complications; difficult to understand the data; incomplete data; inadequate metadata; poor data lifecycle management; poor data traceability; high-paced technological development [37]; inconsistent data [38]; lack of data standards [39][40][41]; and communication of results [42]. Next to the numerous challenges and barriers for big data and open data stands the potential to support decision-making in the thermal energy transition.…”

Introduction of a spatio-temporal mapping based POE method for outdoor spaces: Suburban university campus as a case study

“…• In literature, the use of spatial mapping for the visualization of POE results and transformation of aggregated data into a database has been applied on different POE studies (Hua et al, 2014;Göçer et al, 2015;Göçer et al, 2016;Göçer et al, 2018). In this study, the use of spatial mapping has been revised for outdoor POE studies and enriched as "spatiotemporal mapping" method.…”

Supporting Post-Occupant Evaluation Through Work Order Evaluation and Visualization in FM-BIM

“…While there is little consensus regarding the definition of POE [4], several elements are commonly considered within the scope of such studies: indoor air quality (IAQ), indoor environmental (thermal, acoustic, visual & spatial) quality, space functionality, asset condition, cleanliness, aesthetics, sound privacy, workspace & building features, occupant behaviour, occupant health & safety, and user satisfaction/comfort [5][6][7][8][9][10]. User surveys are the most common source of information for POEs [5], and are often combined with in-situ measurements to contextualize user responses [3,7].…”

“…Few studies have linked BIM with POE, notably the work of Göçer et al [3,9] who created a GIS and BIM-enabled platform to support bi-directional communication between FM teams and users and created a series of supporting BIM visualizations of POE survey results. This paper responds to existing research gap of POE integration within BIM [5] and presents strategies for leveraging maintenance work orders to enhance and complement POEs.…”
