Abstract [en]

Digital twin technology is an emerging technology within the built environment. There are yet many unexplored opportunities to utilize digital twins for facilitating the transformation towards a climate neutral building stock while also meeting the expectations from the building occupants. This article presents a case study of a digital twin, developed for an existing commercial building stock of campus areas in Sweden. The overarching purpose of the digital twin is to support both building occupants and building operators. This twofold human-centric approach represents a novel approach for building digital twins. The digital twin is based on 3D scanning and together with geospatial data, a real-like navigational indoor environment is created. Three innovative features are presented; the building analysis module, the digital twin mobile application and the building operations module. The results show that the digital twin improves the building occupant’s experience by supporting navigation and providing access to room booking system via this dedicated interface. Building management is also benefited by the digital twin through easier access to building data aggregated into one platform and a state-of-the-art analysis tool for optimizing the use of indoor space. The digital twin holds future potential to achieve operational excellence by incorporating feedback mechanisms and utilizing Artificial Intelligence to enable intelligent fault detection and prevention.

Abstract [en]

This PhD thesis is based on four articles, each focused on distinct research areas: building occupants, smarter higher educational buildings, smart building systems and the digital transformation of real estate organizations. Rather than concentrating on one specific research area, the objective was to provide a comprehensive view of the broader system and delve into these four key research areas. Thus, they are all interdependent and require equal attention to facilitate the digital transformation within the commercial real estate industry. This transformation aims to create a more climate neutral built environment while ensuring good quality indoor comfort.

 

The findings reveal a paradox within smart building systems, where building occupants are often treated as passive agents and interactions are intentionally reduced. However, it can be argued that some interactions will be beneficial, as building occupants considered as active agents could contribute to a more sustainable building operation. This study also concludes that current smart buildings are not yet smart enough and that all data is not smart data. Furthermore, the investigation into what constitutes a smart building has led to the identification of key features of smarter higher educational buildings. Finally, the concluding part of this study delved into the organizational challenges associated with digital transformation, proposing potential solutions to enhance innovation processes. Based on these findings, a framework for human-centric digital transformation was proposed.   

Abstract [sv]

Denna avhandling baseras på fyra artiklar som fokuserar på användare, smartare högskola och universitetsbyggnader, smarta byggnadssystem samt kommersiella fastighetsorganisationer under digital transformation. Avhandlingen utgår från ett system med dessa fyra identifierade forskningsområden. Syftet är att visa att de är sammankopplade och att de behöver likvärdig fokus för att kunna dra slutsatser om hur digital transformation inom den kommersiella fastighetsindustrin kan leda till en klimatneutral byggd miljö, samtidigt som ett gott inomhusklimat säkerställs.

Resultaten visar att smarta byggnadssystem liknar en paradox där användare behandlas som passiva objekt och där interaktioner är medvetet reducerade. Trots detta så kan vissa interaktioner vara fördelaktiga eftersom användare betraktade som aktiva objekt kan bidra till en mer hållbar drift. I tillägg till detta kan det sammanfattas att smarta byggnader är ännu ej tillräckligt smarta. Och även att all data är inte smart data. Analyserandet av smarta byggnadssystem resulterade i en identifiering av vad som karakteriserar en sådan smart byggnad. Den avslutande delen av studien analyserade organisatoriska utmaningar med digital transformation där förslag till möjliga lösningar till att förbättra innovationsprocesser var presenterade. Dessa resultat gav inspiration till en modell för digital transformation med människan-i-centrum.
