Integrated BIM-Parametric Workflow-Based Analysis of Daylight Improvement for Sustainable Renovation of an Exemplary Apartment in Seoul, Korea

Abstract

More than 60% of housing in South Korea consists of mass constructed apartment neighborhoods. Due to poor quality construction materials and components, the average operative life of apartment buildings is 20 years. The rapid degradation and low maintenance condition of transparent and semi-opaque components, as well as the limited daylight access in the standard apartment layout, are cause for the lower visual comfort of occupants. This research analyzes the improvement in visual comfort for the renovation of an exemplary apartment unit in Seoul, using Building Information Modeling (BIM) and parametric environmental analysis tools. The existing apartment is virtually reconstructed with BIM software. The building model is exported to Computer-Aided Design software to execute parametric daylight analyses through environmental simulation software. An enhanced modular building envelope and apartment layout are developed to reduce the energy demand for heating, cooling, artificial lighting, and to improve visual and thermal comfort. The visual comfort analysis of the refurbished apartment results in average improvements of 15% in terms of Daylight Factor and 30% of daylight autonomy. Therefore, this research proposes, the renovation of aged Korean apartment buildings to enhance daylighting and visual comfort.

Building Information Modeling Potential for an Enhanced Real Estate Valuation Approach Based on the Hedonic Method

“…In fact, the main properties factors impacting the value depend also on elevation views, 3D geometry, orientation and the 3D location. For example, an apartment in the first floor isn't affected by the daylight factor in the same way as a one in the last floor [17]. Hence, the hedonic method needs to be enhanced in order to consider the real estate valuation in a 3D environment where houses are represented as 3D geometric and semantic objects.…”

“…Building information modelling (BIM) has proven to be one of the major innovations in the building industry. By offering a rich 3D model with geometric, topologic and functional characteristics of the building at the conceptual design phase, opportunities to simulate some parameters related to different domains (energy, noise, property valuation, …) are improved [17].…”

Application of Building Information Modelling (BIM) in the Health Monitoring and Maintenance Process: A Systematic Review

“…The context of existing and future residential structures for hydro-thermal modelling and monitoring tools was another subject for health monitoring [ 244 ]. The advantages of utilization BIM for monitoring and optimization of complex refurbishment cases were the main subject of various studies that investigated the barriers and research directions of this approach [ 121 , 245 , 246 , 247 , 248 , 249 ]. Okakpu et al [ 250 ] identified four dimensions that encompassed the impacts of BIM adoption specific to refurbishment projects and Becker et al [ 248 ] conducted research for data collection and actual modelling.…”

Indoor Thermal Comfort Improvement through the Integrated BIM-Parametric Workflow-Based Sustainable Renovation of an Exemplary Apartment in Seoul, Korea

“…The virtual reconstruction of the exemplar apartment analyzed in this study and the comfort simulations and analyses executed for both its existing and renovated states have been executed through the BIM-parametric renovation framework that has been described by the authors in previous studies [38,39]. Construction data and plans relative to the exemplary apartment building analyzed have been retrieved from the survey of the existing structure, and from literature on the history of housing in South Korea.…”

“…Accordingly, the annual cumulative radiation for the building envelope has been analyzed using the Ladybug tools ( Figure 6). External factors, such as self-shading and shadows from neighboring buildings, and the Expressway, have been taken into account in the parametric analysis [38,39]. Accordingly, the unit located on the 7th floor (18 m) presents the average cumulative annual radiation values and has been selected for the energy simulation of technical heating and cooling loads and indoor comfort analysis of the occupants.…”
