Since 1980’s, the rapid economic growth resulted in so many aged apartment buildings in South Korea. Nevertheless, there is insufficient maintenance practice of buildings. In this study, to facilitate the building maintenance the authors classified the building defects into three levels according to their level of performance and developed a mobile application tool based on each level’s appropriate feedback. The feedback structure consisted of ‘Maintenance manual phase’, ‘Online feedback phase’, ‘Repair work phase of the specialty contractors’. In order to implement each phase the authors devised the necessary database for each phase and created a prototype system that can develop on its own. The authors expect that the building users can easily maintain their buildings by using this application.

Construction System

In South Korea, the need for residential modular buildings has highlighted, due to the increase in demand for small housing and the high land price in urban area. Thus, the cruse housing system (CHS) was developed to build high-rise residential buildings. The object of this study is to analyze the characteristics and fabrication processes of CHS residential buildings when the in-fill construction method is adopted. The result of this study showed that there is the potential to utilize the fabrication processes of CHS in-fill construction system to build high-rise modular buildings.

In Indonesia RC structures are widely used for high rise, low rise, shop offices, as well as residential buildings. In February 2018, the first author introduced an RC beam design application for Android [12] for two options. Option one is for calculating nominal moment (Mn) and nominal shear force (Vn) of the section when the beam dimensions (b, h) and reinforcements are known; option two is to calculate the number of reinforcements for Mn and Vn when the dimensions (b, h) are known. In this paper, the first author added option three, namely the optimization for the design of RC beams when the internal forces are known and the application calculates the most optimal dimensions (b, h) and reinforcements. The application developed is named Civil Engineering Mobile Application for Concrete Beams (CEMA) and is called C2. In CEMA the user can follow the step by step calculation and the results of the calculation are stored in a database. For option three of CEMA (optimization of RC beam sections), the application was validated by another method called Teaching-Learning-based Optimization (TLBO) method [10]. It is believed that CEMA which is based on SNI 2847:2013 can be useful for Indonesian structural engineers designing and supervising actual construction RC buildings.

Building Maintenance

Purpose The current maintenance management method affects the efficiency of the complex, high-rise industrialised building system (IBS) building maintenance management projects in Malaysia. The usage of a conventional system (paper-based reports/unsystematic database) has various drawbacks, such as IBS component aesthetic and structural defects which occur repeatedly in the building and maintenance of conventional building, lack of integration between maintenance systems and lack of the intelligent capabilities of linking defect diagnosis operations in maintenance affecting various building elements with IBS component defect knowledge. Thus, the purpose of this paper is to focus on the development of a mechanism to improve IBS component defect knowledge transfer in IBS building maintenance projects through the integration of building information modelling (BIM). Design/methodology/approach Eight clients/maintenance contractors were selected based on the major problems of using a conventional system to investigate the maintenance management practices in each complex and high-rise IBS building. Findings The findings indicated that several computerised systems such as Building Automation System and Supervisory Control and Data Acquisition System are used by a client/maintenance contractor. Moreover, BIM technology awareness was found to be limited, with no implementation in IBS building maintenance till now. The results of this case study were used as a foundation for the development of a prototype system using Computerised Maintenance Management System, Expert System and BIM. Originality/value The development of this new system improves IBS component diagnosis knowledge integration with the BIM technology.

High Rise

Residential high-rises are unique properties that differ from landed properties such as bungalows or terrace houses. They are unique insofar as, after the properties have been occupied, facilities must be jointly managed by residents. The continuous growth of high-rise residential buildings specifies that there is a need for effective ownership and property management system to instill a valuable living experience among high-rise residents in this country. Looking at this scenario, this research takes an initiative to develop a mobile application that supports streamline information with assistive features to improve communication and information sharing for high-rise residential management in Malaysia. This aim is achieved by answering three research objectives, including identifying user requirements, designing the application prototype and developing the artefact and evaluating the artefact. The study was conducted together with LT Sdn Bhd, the property management company responsible in managing and maintaining property related matters of Seroja Apartment. An adopted conceptual framework for property management based on the sustainable indicator dimensions for property management and applicable features from existing mobile application to develop the artefact has been proposed. The conceptual framework was proposed based on literature review and nature of work observed on site. Lastly, the study successfully validated the proposed adopted framework against the artefact, the MyLT mobile application.

Cooling Energy Demand

Aapartment houses account for more than 60% of the total of residential buildings to be built in South Korea. In particular, a high-rise apartment house with 21 floors or more has steadily increased in densely populated areas. The heating and cooling energy demand of the apartment house is greatly affected by the shape and the thermal insulation of its building envelope. In addition to its functional efficiency, the shape of building envelope in a high-rise apartment house is considered to be an important factor for the urban landscape with diverse construction methods and materials. In this study, we analyzed the heating and cooling energy demand depending on the effective heat capacity of building structure and the installation position of thermal insulation materials as the design conditions of high-rise apartment houses. This study used the ECO2 energy analysis program for the building energy efficiency grading certification system in South Korea.

The Impact

This article investigates the possibility to enhance the use of latent heat thermal energy storage (LHTES) as an energy retrofit measure by night ventilation strategies. For this scope, phase change materials (PCMs) are integrated into wall and ceiling surfaces of high-rise residential buildings with highly glazed facades that experience high indoor diurnal temperatures. In particular, this article investigates the effect of night ventilation on the performance of the PCMs, namely, the daily discharge of the thermal energy stored by PCMs. Following previous experimental tests that have shown the efficacy of LHTES in temperate climates, a system comprising two PCM layers with melting temperatures selected for a year-around LHTES was considered. To quantify the effectiveness of different night ventilation strategies to enhance the potential of this composite PCM system, simulations in EnergyPlusTM were performed. The ventilation flow rate, set point temperature, and operation period were the main tested parameters. The performance of the PCMs in relation to the variables was evaluated based on indoor operative temperature and cooling energy use variations in Toronto and New York in the summer. The solidification of the PCMs was analyzed based on the amount of night ventilation needed in each climate condition. The results quantify the positive impact of combining PCMs with night ventilation on cooling energy reductions and operative temperature regulation of the following days. In particular, the results indicate higher benefits obtainable with PCMs coupled with night ventilation in the context of Toronto, since this city experiences higher daily temperature fluctuations. The impact of night ventilation design variables on the solidification rate of the PCMs varied based on each parameter leading to different compromises based on the PCM and climate characteristics.
