The havoc caused by COVID-19 has further strengthen the case for greening cities and ensuring a quicker economic recovery much desired by various governments. To this end, the appetite for Distributed Renewable and Interactive Energy Systems (DRIES) as a preferred option to retrofit cities has grown amongst policy makers. However, DRIE sources are complex and disparate presenting challenges integrating into a unified system for urban retrofitting. Yet, integrating Building Information Modelling (BIM) and DRIES provide possibilities of effective assessment. Research of BIM applications at a city level is still very sketchy talk less in the domain of DRIES. This study investigates the opportunities and barriers of the application of BIM for the performance assessment of DRIES in the context of the transforming our environments into lowcarbon cities. A systematic literature review and case study review were used to achieve the aim of this study.

Interactions and collaboration between parties in construction projects are often characterised by misunderstandings and poor information exchange. Game engine technologies, when employed with building information modelling (BIM), can help address these shortcomings. Quite often, the visualisation capabilities of BIM models are not explored fully partly because of their limited interactive capability. While game engines are powerful in visualisation and interactions in the gaming industry, the literature suggests a lack of understanding of the applicability of the same in construction. This study investigates the potential of the use of game engines in construction practice which culminated in a framework that can guide the implementation of the same in enhancing interactive building walkthroughs.
