A Proposed Methodological Considerations for Sustainable Chemical Process Design

Chemical manufacture is a significant value-added industry in both local and global economies. Along with highly relevant issues such as unsustainable process design, energy consumption, and waste generation linked with the sector, societal issues relating to chemical product health and safety are part of the greater sustainability concerns. There is a need to design a sustainable strategy while ensuring economic stability at the corporate level. Hence, this paper presents a methodological proposal of integrated modelling approach for sustainable chemical process design at early design process. The step of achieving this objective is separated into several parts. The first step is to classify parameters from established tools as a benchmark for sustainability metrics. The next step is to transform quantification value of triple bottom line impact (economic, environment and social) to normalized weightage by using Multi Criteria Analysis. The final stage is to develop alternative in terms of technical optimization of process design. The implementation multimodal Multi Criteria Analysis and optimized process design exhibits significant improvements in sustainability impacts according to the waste reduction (WAR) algorithm.

Applying a Systemic Approach for Sustainable Urban Hillside Landscape Design and Planning: The Case Study City of Chongqing in China

Rapid urbanization has led some Chinese cities to extend to hillside sites with recurrent patterns of flattening sloping terrain to erect high rise buildings. This approach usually results in disturbing local ecosystems which protection is an important requirement towards achieving the UN 2030 Sustainable Development Goals. Studies examining the special patterns of urban extensions onto hills and the driving forces of behind the deterioration of environmental quality in cities are scarce. This paper aims to answer two questions; “What are the definitions and goals for sustainable landscape design for hillside urban extensions?” and “What are the real causes for the unsustainability of current urban hillside housing developments?” These questions will be approached, first through a literature review, and second through considering the case study of Chongqing Yue Lai eco-city and examining the limitation and remediation through the whole process of the land construction loop within the systemic approach. This article illustrates how sustainable urban hillside landscape design and planning can be achieved by balancing the priorities of four key stakeholders (government, developers, city dwellers, and local ecosystem). This calls for shifting from the central planning system dominated by local governments by including the equally important priorities of its citizens (human actors) and non-human actors (ecosystem).

Revisiting the System Energy Footprint and Power Efficiency on the Way to Sustainable 6G Systems

It is expected that the 6G architecture will bring much better network economics and energy efficiency through a heterogeneous architecture that natively blurs the boundary between dedicated network infrastructure and devices. In this context, we foresee that 6G devices will not only be communication endpoints, but they will also be able to act as active network nodes in a data path. As the impetus of climate change calls for a sustainable 6G system design approach toward carbon neutrality, it is time to revisit the power management strategies across devices and networks in cellular systems in a fundamental and holistic manner.

“Biophilia as a Sustainable Design Approach for University Buildings Design: a case study in university campus drawing studios Cairo, Egypt.”

University campuses have a long history of enriching the social, cultural, and economic value of societies. Worldwide, there is a rising demand for the integration of new approaches into the planning and design of university buildings to further improve their quality. According to the literature, many approaches needed to be considered while designing university buildings that can enhance students’ performance. Biophilic design is known to have enhancing levels of interaction, and interaction patterns, enhancing health and wellbeing in terms of physiological, psychological, cognitive, and social/ spiritual benefits, while rigorous scientific evidence that supports such claims is rare. Many researchers have previously investigated the application of biophilic elements in working environments, however limited research is related to university building designs, specifically in Egypt. There is limited research on methods for quantifying the effect of biophilic design patterns on the physiological, and cognitive benefit. Thus, in light of the concept of Biophilia, this research aims to identify the correlations between the biophilic patterns and enhancing student performance. Survey questionnaires were administrated to a sample of students who regularly use the selected drawing studio. The extracted data will be analyzed through the use of SPSS software. This paper will benefit researchers who are interested in this field and may serve as a suitable beginning point for them and designers as well as a guideline while designing a university using biophilic patterns.

A Flexible Robust Possibilistic Programming Approach for Sustainable Second-Generation Biogas Supply Chain Design under Multiple Uncertainties

The goal of this research is to develop a novel second-generation-based biogas supply chain network design (BG-SCND) model that takes into account the triple bottom line approach. Biogas is a promising renewable energy source that can be obtained from a variety of easily accessible second-generation wastes, including animal manure, municipal waste, and agricultural leftovers. Integrated optimization of the biogas generation system is essential for a speedy and environmentally friendly transition to sustainable biodiesel production. The dynamic environment of the energy market significantly impairs the decisions of the BG-SCND model; therefore, a hybrid solution approach using flexible programming and possibilistic programming is suggested. To verify the suggested model and approach for solving the problem, a thorough computational analysis of a case study is conducted. The case study findings demonstrate that considerable investment is necessary to attain social and environmental well-being goals and safeguard decisions against epistemic uncertainty. Policymakers involved in the planning of biogas production and distribution projects may find the proposed approach useful.

Potential mutual efforts of landscape factors to improve residential soundscapes in compact urban cities

Multifaceted approaches covering various environmental dimensions are essential for improving urban residential soundscapes efficiently in compact urban cities. Particularly, visual landscape factors have been considered as influential for soundscapes. Nevertheless, how potential landscape attributes mutually contribute to the improvement of soundscape qualities across different urban environmental contexts has not been comprehensively investigated. The present study demonstrated evidence of mutual efforts of landscape factors for improving residential soundscapes in compact urban areas. From cross-sectional surveys across public residential blocks in Singapore, seven combinations of window views based on five visual landscape components and their intrinsic qualities were identified. Multivariable analyses adjusting for urban neighborhood contexts, demographic confounders, and physical landscape/soundscape covariates were conducted. The results found that urban residents having a natural and/or open view through a window perceived greater soundscape pleasantness compared to their counterparts (i.e., artificial and closed views). In contrast, window views modified by man-made structures of buildings (i.e., human-modified views) negatively affected soundscape pleasantness, regardless of whether these views were slightly or heavily modified. Although the majority of high-density residential estates may face such low-quality window views in real situations, their adverse effects can be supplementally controlled by implementing water-type neighborhood landscapes or waterscapes. The findings of the present study offer valuable insights into prominent landscape attributes and their mutual and multifaceted contributions for urban soundscape improvements in real-life residential scenes, offering practical implications and sustainable design approaches for urban residential planners and managers.

A Methodical Framework for Sustainable Architectural Design: Housing Practice in the Middle East

In developing countries where sustainable housing design receives insufficient theoretical and practical efforts, decisions about appropriate sustainable design strategies are often made in ignorance of situational and contextual issues and isolation from local practices. The study attempts to provide a design framework that comprises various design models for sustainable housing, enabling architects worldwide to broaden their sustainability practices in the architectural field. The study employs the grounded theory method to transform theory into viable housing design models for architects in various regions, particularly the Middle East, who will be able to trace the regional models and select design approaches and strategies in response to local situations. The research is divided into three stages. Guy and Farmer’s six logics are linked with methodical sustainable design approaches through comparative analysis to develop design models that will be chased in sustainable housing practices. The models are introduced in the next phase within a design framework and, finally, verified through Middle Eastern practices. The framework, which has been verified by tracking sustainable housing models in the design practices of Middle Eastern countries, can be used by applying the design models individually or by combining more than one model to create more responsive sustainable design practices in the housing field. The novelty of the study is that the developed framework transforms theoretical models into viable options for designers and scholars around the world, as well as enabling architects and developers in Middle Eastern cities to easily and practically trace regional design models and to select appropriate design approaches and strategies in an integrative manner.

Cultural identity of places through a sustainable design approach of cultural buildings. The case of Riyadh.

Architecture in Saudi Arabia has undergone significant changes in recent decades due to rapid planning and massive expansion, especially in the major cities of Riyadh, Jeddah and Dammam. In the strategic framework of the Saudi Vision 2030, Saudi Arabia will become one of the major destinations for international visitors, thanks to its cultural heritage. It is, therefore, necessary to ensure a design of contemporary buildings that reinforce the identity of the place by reflecting the local culture through a sustainable approach by responding to the site and the climate, strengthening the quality of the indoor environment for the health and well-being of people. This paper seeks to identify relevant criteria for architectural design in which sustainability and cultural identity are strongly related. These criteria arise from a critical reflection on various factors fundamental in public buildings design, such as the historical knowledge of the place, recognition of significant pre-existing buildings, climatic aspects, and the health and comfort of building occupants. Riyadh, the capital of Saudi Arabia, one of the fastest-growing cities in the Middle East, is selected as a case study. This study takes the project of a cultural centre in Riyadh city as an experimental verification of these theoretical assumptions. The aim is to strengthen the cultural identity of the place through social and cultural spaces that reflect Saudi culture while at the same time preserving the environment and natural resources. A well-managed and actual design of cultural buildings in the selected case study in Riyadh is essential to promote culture and heritage to reinforce the sense of regional and national identity towards a sustainable design approach. In this investigation, the paper attempts to define guidelines through a cultural and sustainable strategy that can be generalized to other Gulf countries.

A High Output Triboelectric–Electromagnetic Hybrid Generator Based on In‐Phase Parallel Connection

AbstractWith the advent of carbon neutrality, renewable energy installations are being upgraded toward miniaturization, low cost, and high conversion efficiency. Thus, a high output triboelectric–electromagnetic hybrid generator based on in‐phase parallel connection (IP‐HG) is proposed. The output characteristics of both TENG (triboelectric nanogenerator) and EMG (electromagnetic generator) can be effectively complemented to provide excellent output over a wide range of operating frequencies. By connecting multiple TENGs in parallel with EMGs in the same phase respectively, cumbersome rectification elements and wiring can be eliminated, and the energy output of the device can be greatly increased. The output characteristics and advantages of the IP‐HG are systematically investigated, including the material of the TENG, the rotation speed, the combination of dielectrode, and their effect on the electrical output of the IP‐HG. The short‐circuit current of 63 mA, open‐circuit voltage of 80 V, and an instantaneous output power density of 610 W m−3 is obtained by using a full‐wave rectifier circuit at 243 rpm, which can charge a 470 μF capacitor to 1 V in 0.2 s. A maximum output efficiency reaches 36.162% at 189 rpm. In addition, the IP‐HG can continuously power a commercial sensor and three 5 W DC light bulbs at very low rotational speeds. The reported IP‐HG offers an efficient and sustainable design approach to the development of hybrid harvesters.
