Studies discovered that humans spent around 80% of our time indoor and this phenomenon is deteriorating our health physically and psychologically. Thus, it is important to study the effects of different interior designs on our emotions. The previous studies and researches done on interior spaces are mostly focusing on measurable physical attributes of interior whereas the psychological relationships between interior design criteria and human emotions have not been well studied. Therefore, this research paper aims to determine the suitable interior space for youngsters from different backgrounds in terms of spatial quality and materiality. In this paper, 4 types of commonly-used materials in Malaysia, namely Timber, Concrete, Bricks and Stones are selected to be studied and analyzed based on the respondents’ preferences and perceptions of warmness or coolness of materials. The results showed that there is no distinctive relationship between respondents’ preferences to materials and their educational backgrounds but respondents of different races showed different degree of acceptance towards different finishing materials. The paper proof the respondents prefer to have warm-feeling materials such as timber and bricks for their home design as compared to cold-feeling materials such as concrete and stones. The results will serve as a material-selection guideline for designers.

Sustainability principles impact green building infrastructure design, planning and construction decisions. The influence of social perceptions in transforming notions of green architecture and sustainable designs as desirable are also interesting contexts for urban design researchers in addressing environmental impacts. The aim of this paper is to discuss a breadth of available literature on architectural sustainability, and the many effects of urbanisation. Few scholars have attempted to frame qualitative discussions of sustainability perceptions with regards technological interaction with built environments. Research utilises two green building design frameworks to analyse differences between sustainability perceptions of innovation and environmental design aesthetics, namely technological innovation interaction with architecture, and architectural design interaction with nature. Findings from case studies of three examples namely The Port of Portland, The Pompidou Centre Paris, and Frank Lloyd Wright’s First Unitarian Society are deconstructed using qualitative approach to demonstrate that while architectural interaction with nature is viewed as ideal characteristics, green building design innovations with technological interactions play a larger role in influencing social perceptions towards sustainability. Findings suggest that green buildings should encompass a wider range of aesthetic-based designs, from passive ventilation to lighting systems and materials, but in order to sustain positive stakeholders’ perceptions, social benefits and education among green building policymakers, designers and architects is crucial. Recommendations on how to cultivate a balance in pragmatic, cost-conscious approaches, including interactions with technologies, will be discussed in conclusion.

Economic growth in developing countries requires the implementation of infrastructural projects such as power plants, the sustainability of which plays an important role in the social, economic, and environmental development. Despite, these projects are always associated with uncertainties and risks due to features such as uniqueness, unspecified time, the need for specific equipment, correlation between different phases and so on. Therefore, in the present study, a small-scale power plants in Mazandaran was subjected to a case study by which the project risks were properly studied. By interviewing the experts associated with the construction of the power plant, 34 risks were identified and subsequently categorized into four categories of environmental, economic, social, and technical. Then, using the failure factor analysis method, their effects were evaluated, and critical risks were identified. In the next step, Fuzzy TOPSIS hierarchical analysis method was used to prioritize critical risks according to the project objectives in accordance with the PMBOK project management standard. After prioritizing the critical risks, in accordance with the real conditions of these projects, suggestions were made to respond and face the critical risks

Income growth rates are required to justify decisions and strategies for property investments. Although existing studies addressed this phenomenon in freehold investments, a relative question regarding the determination of rental growth rates of leasehold investment properties valued part-way through rent review periods has not been addressed before now. This study examined the spreadsheet-assisted scenario analysis tools and techniques that are required for the determination of rental growth rates of leasehold investment properties valued part-way through rent review periods. A precursor to the scenario analysis was the development of a hybrid leasehold DCF valuation model arising from the equation of the formula for reversionary leasehold equivalent yield valuation to the formula for reversionary leasehold growth explicit DCF valuation model; thereby culminating into the identification of four unknown variables comprising the all risks yield and the implied growth rates of leasehold cash inflows and cash outflows which were subsequently derived using the solver tool of Excel®. From a total of eleven scenarios generated, the 9th successive scenario produced optimal results indicating zero slack between iterated and calculated values for the growth rates of leasehold cash inflows and cash outflows respectively. With recourse to the hybrid leasehold DCF valuation model, the spreadsheet-assisted scenario was found to produce mathematically valid growth rates that justify the valuation of leasehold investment properties part-way through rent review periods. The value of this research is the analytical tools and rigour it avails investors seeking income returns and growth from reversionary leasehold property as an instance of terminable investments.

People tend to spend approximately 87% of their time in the indoor environment. There is a possibility that they are exposed to volatile organic compound (VOC) and particle pollution, and to experience stress related disorder. This has potential threaten the well-being of indoor occupants if left untreated. Hence, plants were introduced to alleviate these negative impacts. This paper reviews past literature from 1990 to 2010s, to examine the relationship of plants with indoor environment and identifies how they influence people, psychologically and physiologically, and how they promote indoor environment quality. Most studies suggest that the presence of plants is associated with positive feelings and able to enhance productivity. In addition, they also may help to promote general health such as reducing blood pressure, perceived stress, sick building syndrome, and increase pain tolerance of the patient. Moreover, plants also help in improving the indoor environment quality (IEQ), for instance, they can reduce carbon dioxide (CO2), indoor ozone (O3) level, VOC, and particulate matter accumulation through bioremediation process. Despite all the benefits that the plants could offer, several studies pointed out that factors such as gender, perceived attractiveness of the space, physical characteristics of plants, and methods of interaction with plants may lead to non-identical results. Hence, the selection of the right species of plant in an indoor environment becomes mandatory in order to improve the indoor environment quality; to provide restorative effect; to invoke positive feelings and comfort of the people. In conclusion, this review may provide notable insights to landscape architects, gardeners and even interior designers to choose the right species of plant in an indoor environment, to maximize their psychological and physiological benefits, at the same time, improving indoor environment quality.

A restorative environment tells how certain types of environment help heals people mentally and physically, and many studies in the related field have drawn connection that natural and green places are more likely to be restorative to a person’s health, especially when compared those living in cities. In Kuala Lumpur, rapid urbanization and previous poor city planning result in residents becoming increasingly susceptible to mental fatigue and urban stress. Residents frequent for the very few urban parks available as a place to restore themselves, thus the restorative qualities of the urban parks are critical to elevating the quality of life. This study investigates the theory of restorative environment and highlighting its criteria in the context of Kuala Lumpur, by analyzing an existing urban park as a case study: the Perdana Botanical Garden. The methods used include site observation, interview, and a questionnaire to evaluate the quality of the environment as well as user perception. Data from finding confirms the restorative theories as perceived by users and its suggested space criteria and shows that most users come to the park as green therapy and to relieve stress and relax, as they find that the natural scenery and engaging landscaping inside the park are restorative to their overall well-being.

The environmental factors in the educational spaces along with the other factors affect the teaching and learning process. One of the characteristics of environmental space is the type of relationship of each space with its outdoor space. This factor is more important, especially in the spaces where students spend long hours such as architectural design studios. Nowadays, outdoor spaces in academic environments provide functions like accessing to closed spaces and various buildings and creating their relationship. In this regard, the visual function is considered as another important function, which is often overlooked and less considered and created by the outdoor environments for indoor closed spaces. The main question is related to whether the type of the relationship between the closed space of the architectural design studio and the outdoor natural space is considered as an important factor in achieving students’ satisfaction with long hours working in this space based on the attention restoration theory or not. The present study aimed to examine the effect of the relationship between the indoor spaces of architectural design studios and outdoor environment on increasing students’ satisfaction. This research was conducted by combining the quantitative and qualitative methods. The population included 65 students majoring in architecture, who experienced designing classes in all three studied studios. This research compared three architectural design studios with different conditions of proximity and outward view. The research data were analyzed with SPSS software. The results indicated that the open and diverse outdoor natural landscape was more effective factor in increasing students’ satisfaction rather than among the various factors influencing the type of relationship between the studios and the outdoor space. Accordingly, designing the university landscape from the indoor closed spaces should be considered more, especially in spaces such as studios due to the long hours of attending and working of students.

Municipalities are in search of exploring alternative own revenues to finance urban infrastructure investments in India. As compared to others, monetization of public land is within the functional domain of local governments subject to certain constraints. This study employs a linear programming model incorporating the constraints enforced by state government to assess the potentials of public lands for urban infrastructure capital investments. This approach is largely different from the existing literature, which does not determine the capacity of municipal public lands based on realized revenues. This investigation finds that certain proposed leasing strategies for Guntur Municipality under different simulations as done in this research have potentials to realize 240% more revenues compared to ‘business as usual’ scenario and hence, provide new policy insights for leasing public lands in a revenue optimization perspective. The framework adopted by this helps local governments to estimate the potentials of public lands and establish revenue targets.

Diverse causes of accidents abound on construction sites, which lead to complexity and difficulty in understanding the key causes of accidents on construction sites. The effect is the increasing rate of accidents. Thus, grouping and identifying the key dimensional and sub causes of accidents is important. However, there is a dearth of research on the dimensionality and indicators of causal factors of accidents on construction sites. This paper aims to create an avenue for easy identification and understanding of the causes of accidents through the development of key indicators and dimensional causes of accidents on construction sites. Adopting a cross-sectional survey research design, three hundred questionnaires were purposely distributed to construction workers who have had experience or witness accidents on a construction sites. Two hundred questionnaires were retrieved and used for analysis representing a 67% response rate. An exploratory factor analysis was used to group and find the significant causal factors from the 64 factors identified in the literature. From the analysis, five key dimensional causes with 22 indicators were identified namely; personal and work factors, design factors, behavioural factors, proximate factors and attitudinal factors. The key indicators identified among others are non-use of PPE, lack of experience, working in confined spaces, disobedience to work discipline and innovative technology. To reduce the occurrence level of accidents, site managers should place the key indicators and dimensional causal factors of accidents on the signboard for easy identification and understanding and as a training guide on construction sites

In South-East Asia, the Malay architecture is among the popular subject of research because of its historical importance within the region, apart from many others. To some researchers, the Malay architecture is unique because of its intangible meaning and historically rich design characters. It is difficult to be reproduced, and only limited numbers of people are acknowledged as experts. With the introduction of technology such as BIM, it is hypothesized that the gap can be minimized. The idea of this paper is to outline the process of recreating cultural architectural design using a modern process such as Building Information Modelling (BIM) platform in specific, from data collection using Terrestrial Laser Scanning (TLS) and digitalization process in Revit software. This paper employs observation approach using data from laser scanner collected from case study and content analysis technique. While normally most of the cultural architecture is undocumented, the findings of this activity are aimed to provide guideline to develop geometrical information for heritage-enthusiast in practicing their undertakings. It is hoped that more historical and cultural architecture can be recreated and appreciated for the use and inspiration of current construction industry
