High Rise

The development of high-rise buildings is a current trend in developed cities to answer the challenges of population growth, adding aesthetic value, and optimal use of land. Lagos particularly is one of the fastest growing cities in the world with Gross Domestic Product (GDP) and Internally Generated Revenue (IGR) in Nigeria, which suggests the need for multiple complex buildings, and the need for their maintenance cannot be overemphasised. This maintenance aspect requires tremendous work due to the complexity attached and several strategies springing up. Different studies reveal that both performance measurements and factors are essential aspects in evaluating maintenance management. Thus, this study seeks to explore performance elements that could improve maintenance. Personnel attitude, maintenance policy, maintenance review, and maintenance implementation were measured relative to computerised maintenance management system (CMMS) performance. With a random sampling technique, a sample of 134 Facility Management (FM) practitioners involved in high-rise office buildings was used to assess the effects of CMMS deployment. Results were analysed by Partial Least Squares Structural Equation Modelling (PLS-SEM). Findings from this study highlighted an indirect effect size and a large predictive relevance of personnel attitude as a critical factor for a smooth maintenance execution procedure of 12.59% and a standard operating procedure (SOP) of 15.64% on maintenance implementation to contribute 28.36% to performance. This paper uncovers the place of personnel attitude in determining effective maintenance.

Sets Theory

Condition information is essential to develop effective facility management (FM) strategies. Visual inspections and walk-through surveys are common practices of condition assessment (CA), generally resulting in qualitative and subjective outcomes such as “poor”, “good”, etc. Furthermore, limited resources of the FM process demand that CA practices be efficient. Given these, the purpose of this study is to develop a resource efficient quantitative CA framework that can be less subjective in establishing a condition rating. The condition variables of the study—mean time between failures, age-based obsolescence, facility condition index, occupant feedback, and preventive maintenance cycle—are identified through different sources, such as a computerized maintenance management system, expert opinions, occupants, and industry standards. These variables provide proxy measures for determining the condition of equipment with the implementation example for heating, ventilating, and air conditioning equipment. Fuzzy sets theory is utilized to obtain a quantitative condition rating while minimizing subjectivity, as fuzzy sets theory deals with imprecise, uncertain, and ambiguous judgments with membership relations. The proposed CA framework does not require additional resources, and the obtained condition rating value supports decision-making for building maintenance management and strategic planning in FM, with a comprehensive and less subjective understanding of condition.

Development And Validation

The present study aimed to develop an indigenous measure of learning styles for e-learners in Pakistan and to establish its psychometric properties. The objectives of the study were attained via three studies. First, the items for the development of the Learning Style Scale for e-Learners (e-LSS) were generated empirically based on a 5-point Likert-type scale. In Study I, the internal consistency and dimensionality of the measure were determined by sampling 360 e-learners aged from 20 to 40 years through a convenient sampling technique, whereas other demographic characteristics were kept in close consideration. For this purpose, exploratory factor analysis was utilized. In Study II of scale development, the factor structure that emerged in Study I was confirmed via confirmatory factor analysis using structural equation modeling. In Study III, the convergent and divergent validities of the newly constructed scale were established by correlating scores with preestablished scale scores that assess the similar construct (i.e., LSS) and with scores on the discriminant construct (i.e., Solving Problems Survey). The sample for this study consisted of 80 e-learners aged from 20 to 40 years. A total of 29 items were confirmed in the final scale with 8 distinctive factors (namely, visual, auditory, kinesthetic, global, analytical, individual, collaborative, and technological type) with sound psychometric properties. To conclude, the newly constructed scale was a significant addition to assess learning styles particularly of e-learners in the context of Pakistan.

Double Skin Facades

There was an indication that high rise buildings in Jakarta was not designed based on energy conservation principles. The most important aspects of the high-rise buildings is energy saving technology located in the building envelope design. Building envelope with a full glass design functions for widening view and enhancing natural lights, even though but it is also increasing energy consumption and thermal discomfort due to the intensity of solar radiation in hot humid climates. During the current decade, the development of double building envelope type (Double Skin Façade: DSF) seemed more just to improve the aesthetics and the use of natural light, while the wind and thermal performance aspects were still lack of serious consideration. Those aspects will be chosen as the subject matter in this research. The research was aimed to investigate and compare the value of heat transfer in the building envelope of high-rise office buildings. Samples were taken from five DSF buildings, with closed and open cavity. CFD software is used for simulation of the five different models of DSF. The research proves that the high-rise office buildings as the research object in Jakarta do not apply energy conservation principle. The utilization of wind in the DSF cavity can reduce temperature and relieve the burden of air conditioning systems that is energy save. An important finding of the research is the need for ventilation in the design of a double skin at high-rise office buildings in the humid tropics.
