A generative approach to explore residential urban form potential based on environmental performance for energy efficiency Foram Bhavsar, Vibha Gajjar, Utpal Sharma, Darshi Kapadia E3s Web of Conferences, 2024 The United Nations predicts that by 2050, 70% of people will live in cities, which will bring significant environmental challenges, including climate change and resource depletion. In India, the residential sector account for 30% of total energy consumption. Therefore, it is crucial to optimize energy use in residential structures to address urban population growth, density, and energy efficiency. This study explores the use of genetic algorithms for multi-objective optimization in the design of energy efficient residential urban forms linking urban population growth and environmental concerns. Urban form significantly influences energy consumption within neighborhoods. However, introducing genetic algorithms into urban planning, a field not typically associated with such computational methods, presents considerable challenges. This research addresses complexities such as simulating and optimizing energy use by focusing on the control of solar radiation and the enhancement of natural daylight within residential neighborhoods. It further seeks to enhance the quality of life in open spaces by improving the sky view factor and the sense of spaciousness, adding another layer of complexity to the optimization. In response to these complexities, a framework is developed using the Biomorpher plugin, integrating genetic algorithms in Grasshopper. This research, carried out in Ahmedabad, India, progresses in two primary phases. The experiment progresses in two phases: first, developing prototypes considering factors like Floor Space Index and building types; and second, refining these through multiple design iterations based on environmental criteria. The study generates a diverse range of optimized scenarios, such as low-rise, mid-rise, and high-rise densities, to understand the relationship between residential form and energy consumption. The research identifies energy-efficient configurations through analysis, offering adaptable solutions tailored to specific environmental and spatial contexts.Additionally, it offers a replicable methodology for urban designers and policymakers.
Comprehending Left Over Spaces as Active Urban Spaces: A Case Study of Spaces Beneath Flyovers of Surat Parth Jamadar, Vibha Gajjar Future is Urban II Urban Resilience Capacity Building Nature Based Solutions, 2024 Actuality of public spaces for social interactions is crucial for the city and its functioning. It can aid in fostering a city to be more sustainable, safe, and in turn, make it more habitable. Usually, in a planned city, public spaces are designed with some intentions, along with considerations about the demands, and context of the place. But due to recent rapid – shambolic development, residual spaces and voids are generated as a byproduct. These spaces are dormant and neglected in most cases. Thus, such land parcels can become a possible area of research inquiry for transforming them into potential public spaces. They can become passive or active depending on its location, accessibility, edge conditions, shape, size and other features of urban elements. There are some cases where spaces are created due to a lack of planning or design, which can be termed as “LEFT-OVER SPACES”. These are like a liability to the constantly growing urban fabric, like the leftover spaces beneath fly-overs. But, they have a great potential of becoming a fruitful public space. It has the probability of becoming a blend, associating built environment with open spaces. This paper is an attempt to assimilate the learning from various existing case studies around the world. Thereby, effectively integrating a combination of formulated spaces with their urban context such that they generate utility and engagement eventually contribute to sustainability. The rejuvenation process of converting the residual urban patches is the need of the future and not a liability.

Deliverable to improve air quality using NDVI analysis for Ahmedabad City: Addressing the agendas of SDG Vibha Gajjar, Utpal Sharma, M. Hetankshi Shah Current Research in Environmental Sustainability, 2021 The pace of urbanization and challenges accompanied by the development process for cities need urgent attention from various perspectives. The recent trends of city development not only show the depleting environmental conditions but shows the lack of concern to address such issues. The deteriorating environment in urbanizing areas has gained attention globally and locally. Globally, it has been addressed through the Sustainable Development Goals. At different scales of planning and decision making, they are resolved using the specific targets. Many approaches are locally possible to negotiate the impacting factors of the deteriorating environment and increasing pollution levels. It tries to address the concern highlighted by Sustainable development goals and their targets set for mitigating the problems and describes the Air pollution aspect for the city of Ahmedabad. Out of such concerns, this research paper tries to focus on SDG 11 (Sustainable Cities & Communities) and SDG 15 (Life on Land) to gain insight into the situation through a case study based approach. It also scrutinizes the prevailing practice of the Developmental processes and focuses on alternative means of assessment using NDVI analysis for helping informed decision-making process in the development of the city.
