The 19Th Century

Although the term ‘urbanisation’ was first coined in the 19th century, the phenomenon experienced a significant impact and received a lot of attention in the 21st century. One of the major results is density, causing effects such as excessive demand for residential buildings. To cope with the increasing urban population and limited land availability, cities can no longer opt for horizontal development strategies. Going vertical seems a practical solution, but it can lead to convoluted problems if it is not done with proper planning and mitigation measures at the preliminary stages of planning. This article describes the challenges of residential planning density for high-rise development in Malaysia using a systematic literature review on three identified real cases which separated by pre-development, post-development, and development control. The findings show the major challenges in pre-development and post development related to dissatisfaction with the increasing numbers of high-rise residences due to the increase in population and residential density. As a strategic development control, there must be uniformity in the act or law to control the development of this highrise residential. Thus, this article led to a better understanding of density related to high-rise residential development in Malaysia.

Strong Sustainability

This paper presents an experimental scenario aimed at bridging the gap between the cities we have and the cities we need, not only in the 21st century but also beyond, using the integrated tools of development control and holistic land development model to achieve a planner-led vision of city sustainability. Due to scathing criticisms against the development control system, the paper contends that planners as development approving officers and public interest specialists are better positioned than allied professionals to increase city sustainability through a holistic development process that benefits from the concept of strong sustainability posited by ecological economists. The paper adopts a seven-stage, 56-cell land development matrix (model) to simulate the development of the typical high-rise residential condominium in Ontario, supported with secondary data and the author’s ground experience as a planner and realtor with condominium customer service experience across Toronto and Mississauga cities between 2008 and 2017. Findings reveal that planners can seize the opportunity of being leaders of the development team to synergize the risks and value creation in land development that are key drivers of strong sustainability. The paper suggests some policy implications for averting disasters like fire hazards and terror attacks in high-rise residential buildings.

Storey Building

St. Petersburg’s strict limit on building height existed until the 1960s. A small loosening of restrictions occurred only at the end of the 19th century, which formed the “horizontal” silhouette of the city with a few spire accents, domes and factory chimneys. In the USSR during the 1960s, a multi-storey building system began to develop. As this inclusive unification spread throughout Leningrad, 9-storey, 12-storey, 16-storey residential buildings became widespread. The population’s attitude to them was quite critical. When Russia became a market economy country, St. Petersburg began to actively feel the influence of globalization in the architectural and construction industries. A consequence of the development of new technologies has become the mass construction of residential buildings that are 22–25 floors in height (including buildings closely located to the historical center). Fire safety issues were discovered, and problems concerning soil conditions were uncovered. The high buildings’ influence on the protected center landscapes were very negatively received by citizens. In spite of the approved building regulations, there are many problematic situations; for example, the project of a 400-meter skyscraper next to the monument of Smolniy Cathedral provoked many debates in the city.

The article is devoted to the justification of the need to reduce the population density in the residential development of cities. The analysis of vulnerability of the urban population from threats of emergency situations of peace and war time, and also an assessment of provision of the city by a road network is given. Proposals have been formulated to reduce the vulnerability of the urban population in the long term and to eliminate traffic congestion and congestion — jams.

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.

Probabilistic Risk

Given that existing fire risk models often ignore human and organizational errors (HOEs) ultimately leading to underestimation of risks by as much as 80%, this study employs a technical-human-organizational risk (T-H-O-Risk) methodology to address knowledge gaps in current state-of-the-art probabilistic risk analysis (PRA) for high-rise residential buildings with the following goals: (1) Develop an improved PRA methodology to address concerns that deterministic, fire engineering approaches significantly underestimate safety levels that lead to inaccurate fire safety levels. (2) Enhance existing fire safety verification methods by incorporating probabilistic risk approach and HOEs for (i) a more inclusive view of risk, and (ii) to overcome the deterministic nature of current verification methods. (3) Perform comprehensive sensitivity and uncertainty analyses to address uncertainties in numerical estimates used in fault tree/event trees, Bayesian network and system dynamics and their propagation in a probabilistic model. (4) Quantification of human and organizational risks for high-rise residential buildings which contributes towards a policy agenda in the direction of a sustainable, risk-based regulatory regime. This research contributes to the development of the next-generation building codes and risk assessment methodologies.
