3D Virtual Learning Environments (3D VLEs) are increasingly becoming prominent supporters of blended learning for all kinds of students including adult learners with or without disabilities. Due to the evidenced effect of architectural design of physical learning spaces on students’ learning and current lack of design codes for creating 3D virtual buildings, this case study aims at evaluating the suitability of the architectural design elements of existing educational facilities and learning spaces within 3D VLEs specifically for delivering blended e-learning for adult students with disabilities. This comprises capturing student contentment and satisfaction levels from different design elements of the 3D virtual spaces in an attempt to issue recommendations for the development of 3D educational facilities and hence initiate a framework for architectural design of 3D virtual spaces to augment accessibility, appeal and engagement for enhancing the e-learning experience of under-graduate, post-graduate and independent-study adult learners with disabilities within these virtual worlds.

Traditionally, studies on the power generation performance analysis of the photovoltaic (PV) modules used in building-integrated PV (BIPV) systems have been based on computer simulations and actual experiments with constraints, resulting in the results being inaccurate and limited. This paper proposes a two-step analysis method that results in a more versatile and reliable means of analysis. The steps are: (1) construction of a mock-up test building in the form of BIPV systems and the collection of a massive amount of operational data for one year; and (2) a statistical analysis of the acquired data using Minitab software (Version: 17, Manufacturer: Minitab Inc., State College, PA, USA) to examine the power generation performance. The constructed BIPV mock-up applies design elements such as material types (c-Si and a-Si) and various directions and angles for different module installations. Prior to the analysis, the reliability of the large database (DB) constructed from the acquired data is statistically validated. Then, from the statistical correlation analysis of the DB, several plots that visualize the performance characteristics governed by design elements, including contour plots that show the region of higher performance, are generated. Further, a regression model equation for power generation performance is derived and verified. The results of this study will be useful in determining whether a BIPV system should be adopted in a building’s architectural design and, subsequently, selecting design element values for an actual BIPV system.

Universities and educational institutions are currently becoming more dependent on delivering courses within online virtual worlds, such as 3D Virtual Learning Environments (3D VLES). There is insufficient research on how environmental and architectural design elements of 3D virtual educational spaces and buildings inside these virtual worlds can affect the e-learning process of the students and their satisfaction and contentment. This study investigates students’ satisfaction from different architectural features used in 3D educational facilities by recording, from surveys, students’ degree of agreeability toward varied design characteristics in different learning spaces within 3D VLES. Defining best perceived design traits can improve 3D educational space design to augment a student’s overall e-learning experience, and lead to general design guidelines for future creation of 3D virtual educational facilities.

As most countries have widespread and growing concerns about the sustainable development of society, the requirement to continuously reduce energy consumption poses challenges for the architecture, engineering and construction (AEC) industry. Performance-oriented architectural design and optimization, as a novel design philosophy and comprehensive evolution technology, has been accepted by architects, engineers, and stakeholders for a period of time. Performance in the context of architecture is a widely discussed definition that has long shown a correlation with visual and cultural attributes. Shifting the paradigm of sustainable development while ensuring that the function and aesthetics of the building are not overlooked has been the focus of public attention. Considering the core design elements that affect energy conservation and style performance, the design and optimization of building envelopes, form, and shading systems were selected as research materials. From the perspective of epistemology and methodology, a systematic review of 99 papers was conducted to promulgate the latest development status of energy-efficiency design. This paper manifests a detailed analysis of the design patterns, research features, optimization objectives, and techniques of current approaches. The review found that performance-oriented design optimization can benefit the entire industry from the heuristic knowledge base and the expansion of the design space while maintaining sustainability. In contrast, challenges such as tools, skills, collaboration frameworks, and calibration models are highlighted.

<p>As urban regions increase in population and density, the need for quietness and spaces of relative calm becomes important to inhabitants’ physiological and psychological health and wellbeing. Noises, and the sounds that create them, are treated as a by-product of urban densification and the advancement of technology. This led to uncontrolled and incidental acoustic environments around notable points of urban densification. Each sound adds together in the acoustic environment to create a composition that is labelled collectively as noise. Those in the professions of planning and designing these urban environments have a responsibility to become the composers of the grand aural experience that is the worldly soundscape.  In response to this design problem, this portfolio explored how architecture can be designed to enable this sustainable densification of noisy urban environments. It proposed the incorporation of psychoacoustics and R. Murray Schafer’s soundscape philosophy (and ongoing related research) into acoustic design. By understanding the complex creation of the aural experience, this portfolio investigated whether the key to living healthily and sustainably in an inevitably sound-filled urban environment laid in the design of soundscape as a perceptual construct.  The investigation translated relevant literature into broad explorations of soundscape design elements at a variety of architectural scales. Using soundscape principles in a design process produced a strong architectural proposition that could solve both densification and acoustic problems. This had widespread and profound implications on architectural design practices. The portfolio therefore prompts further explorations into soundscape design for other architectural problems and applications.</p>
