Slight Growth

An investigation into the effectiveness of bioretention cells (BCs) under potential climatic changes was conducted using representative concentration pathways. A case study of Guangzhou showed changes in peak runoff in climate change scenarios, with obvious growth in RCP8.5 and slight growth in RCP2.6. The performance of BCs on multiple parameters, including reduction of runoff volume, peak runoff, and first flush, were examined in different design storms using a hydrology model (SWMM). The effectiveness of BCs varied non-linearly with scale. Their performance fell by varying amounts in the various scenarios. BCs could provide sufficient effects in response to short-return-period and short-duration storms, but the performance of BCs decreased with heavy storms, especially considering climate change. Hence, BCs cannot replace grey infrastructure but should be integrated with them. The method developed in this study could be useful in the planning and design of low impact development in view of future climate changes.

Abstract In maturing an Area Development Plan (ADP), most of the data used are incomplete, too fragmented, or sometime due to time constraint; need to be deduced down to assumptions. Due to this fact, an ADP is bound to have updates, even during the course of maturing it. This is where the issue starts. Since the conventional approach is "bottom-up", room to accommodate changes is limited; at times require the whole proposal to be reworked. This is because it focuses on getting the best development concept for a given field first before rolling it up to study the network/interrelationship between fields. A "top-down" approach in maturing an ADP intends to better assist any given team to be agile whilst focusing on value added solutions from a strategic bird's eye point of view. The approach in discussion was adopted and tested to a regional ADP study in year 2020 which initially involves more than 1000 fields (discovered, prospects, and leads). This approach allows for any changes throughout the course of maturing the ADP because, its main focus is to get the best network/interrelationship between fields first, before focusing on the development concept of each of the fields. Other benefits that can be observed by adopting the approach in discussion is a shorter study duration. Based on the case study, the study duration was reduced from 10 months to 6.5 months. With shorter duration too, can help the Company in better manage its manpower resources to focus on things that matters.

This paper presents a techno-economic assessment for a unique Isolated Hybrid Power System (IHPS) design which could be used for remote areas isolated from the grid which also has the capability of being operated as a smart the hybrid energy system considering solar and wind energy sources for the purpose of street lighting. Solar-Wind Street light is an intelligent, small scale, and off grid LED lighting system. The modelling design and simulations were based on Simulations conducted using the Data collected and HOMER Energy Planning and Design software tools. Its components are solar panel, wind generator system (PVC blowers), Dynamo, LDRs, battery, LED light, charge controller. The energy stored in battery during day time due to solar panel, get extracted by LEDs during the night time (because LDRs get activated due to absence of sun light). Wind also charges the batteries due to wind which is used for glowing street light. The advantage of this idea is to avoid daily running cost and make the system purely off-grid. In this prototype, we have used 12V DC system to supply energy to the lights.

The Ideal

In the past years, the concept of Transit-Oriented Development has been adopted in cities and countries including Malaysia and Singapore. The integration of land use and public transport stations through Transit Oriented Development (TOD) as part of urban and cities strategy is highly acclaimed in promoting sustainable development concept in cities development. To understand the performance of TODs implementation in Klang Valley, this study has selected eleven stations in of Mass Rapid Transit (MRT) Putrajaya Line as case studies. This paper aims to evaluate the current implementation of TODs in Malaysia, benchmarked against the TOD land use composition and percentage from Singapore’s model. The findings show that Raja Uda, Ampang Park and Persiaran KLCC stations show significant performance. However, Bandar Malaysia North station displayed poor result with the lowest percentage of residential and commercial components. All stations did not achieve the ideal TOD value for residential land use and eight out of eleven stations recorded higher than the ideal TOD value for roads. However, highest number of stations achieved the ideal TOD value for mixed-use and commercial land uses. These results would help policymakers to improve the current implementation of TODs in Malaysia.

Subjective Aspect

The article includes the concept of aesthetics through what has been dealt with in the literature by philosophers and researchers who have addressed this concept in an attempt to derive indicators of aesthetics. The article adopted a descriptive and analytical methodology by reviewing recent literature on the concept of aesthetics and its relation to urban planning and design issues. Many subjective and objective aesthetics indicators have been identified, some of which are classified under real aesthetics, and some under fake aesthetics. The indicators were applied to the Kufa Mosque complex and Sahla Mosque complex as a comparative case study. It was found that the indicators of real aesthetics have a higher weight in determining the final aesthetic judgment on the complex form versus the fake indicators, which in turn reinforced the weighting of the subjective aspect over the objective. This was consistent with the answer to the question directed to the sample about which complexes are more aesthetic. The answer was that the Kufa Mosque complex is most aesthetically. This was proven by the questions directed in the questionnaire, which outweighed the real aesthetic indicators for the Kufa Mosque complex. As for the results of analyzing the indicators of fake aesthetic were equal, as each complex achieved higher values in three indicators. Doi: 10.28991/cej-2021-03091743 Full Text: PDF

Old City Renewal

Along with the increasing development of Chinese urbanization, there have been a lot of cities facing the problem of old city renewal. However, during the process of re-plan and reconstruction of the old city, there is a series of changing that refers to the changing of land-use function, adjustment of land layout and the improvement of development intensity, which would change the load and setting of the urban infrastructures. Therefore, how to renew the municipal facilities safely and effectively to guarantee the routine life of people has become a crucial problem in the old city renewal. This paper takes the case study of Hengdaohezi town emphasizing the discussion on re-planning the municipal facilities in the process of old city renewal. Here, the author suggested that municipal facility planning should be carried out under the premise of safety and reliability. In the process of analysis, it should give consideration on the change of urban function and character as well, in order to make the municipal facility planning more scientific and reasonable providing support for the old city renewal from the perspective of municipal engineering.

With one of the highest population densities in the world, Hong Kong suffers from a lack of public open space. Despite this situation, open spaces provided by government authorities or private developers often do not meet residents’ needs or include residents in the planning and design process. To explore one way that this issue is being addressed, this chapter describes an ongoing placemaking project within Hong Kong’s interstitial network of laneways (里) and alleys (巷). The key historical, sociocultural, and physical features, opportunities, and constraints of these in-between spaces are discussed. This is followed by an in-depth exploration of the case study Magic Lanes, a pilot project that aims to provide more inclusive public open spaces through placemaking and community co-creation.
