In rapidly growing cities like Dhaka, Bangladesh, sustainable housing in urban wetlands and slums present a challenge to more affordable and livable cities. The Container Housing System (CHS) is among the latest methods of affordable, modular housing quickly gaining acceptance among local stakeholders in Bangladesh. Even though container houses made of heat-conducting materials significantly impact overall energy consumption, there is little research on the overall environmental impact of CHS. Therefore, this study
aims to investigate the performance of CHS in the climatic context of the Korail slum in Dhaka. The project proposes a building envelope optimization and visualization workflow utilizing parametric cluster simulation modeling, multi-objective optimization (MOO) algorithms, and virtual reality (VR) as an immersive visualization technique.

Workflor framework
First, local housing and courtyard patterns were used to develop hypothetical housing clusters. Next, the CHS design variables were chosen to conduct the MOO analysis to measure Useful Daylight Illuminance and Energy Use Intensity. Finally, the prototype was integrated into a parametric VR environment to enable local stakeholders to walk through the clusters with the goal of
generating feedback. This study shows that the proposed method can be implemented by architects and planners in the early design process to help improve the stakeholder’s understanding of CHS and its impact on the environment. It further elaborates on the implementation results, challenges, limitations of the parametric framework, and future work needed. Results of Generative design experiment

Kim, J. B., Aman, J., & Balakrishnan, B. (2021). Forecasting performance of Smart Growth development with parametric BIM-based microclimate simulations. 26th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA).
Since New York adopted zoning in 1916, regulations and codes have inarguably formed our built environment in the United States [1]. Municipalities and planners have continued controlling community design with ordinances, master plans, and/or design standards. In decades, numerous planning instruments debuted and vanished, but their success and failure were not obscure as the initial vision and goals ensure. Their impact is often unforeseen in the early planning stage. The point of departure of this research is how to relieve this uncertainty

and in this period, water level rises in the various rivers in the northern part of the country due to heavy rainfall and the flow of water from the upstream hills in India. The Tista, Brahmaputra and Jamuna rivers burst their banks and many villages of northern por�on go under water, many low income rural people become homeless and thousands of hectares of crop damages. Therefore, self-sustained buildings and se�lements during flood hazards become essen�al for communi�es’ resilience. The recent flooding over a few months in 2017 throughout Bangladesh has taken a devasta�ng toll on the rural parts of the na�on, having wiped out and destroyed approximately 500,000 to 600,000 homes, leaving millions homeless and subjected to temporary homes. These homes were mostly made from wood and �n, leaving them very weak and suscep�ble to heavy winds, rain, and flooding. Rebuilt homes will likely con�nue to be poorly built. Ha�rbandha is an upazila under division of Rangpur that has faced serious flooding problems lately and need urgent a�en�on. Therefore, Ha�banda area was chosen as the mainstream to design the prototype self-sustained flood safe home focusing the low income people to survive during flood hazards, which can be applied to the other parts of Bangladesh as well as in other tropical countries.

BRIEF
In this project, we presented a proofof-concept for creating a deep [FAKE] urban fabric inspired by Milan and driven by mountains/valleys. The study looked at how different neural networks (such as CycleGAN and StyleGAN) may be linked to identify the search space for architectural inspiration. Specific semantic references were used as input for a pre-trained network, which outputs data for further analysis using another neural network. Through interpolative and extrapolative techniques, the datasets explored alternative resolutions of the urban environment and assessed potential for emergent
patterns, etc. From a methodological standpoint, we were interested in determining the relationship between different types of neural networks and their capacity to tap creative potential in a focused and/ or heuristic/open-ended manner. Experimentation with several linked deep learning models was used to prototype novel design procedures. The testing and assessment of experimental workflows was undertaken through the prism of process-creativity rather than product-creativity.

BRIEF
Smart cities have embraced the integration of big data and artificial intelligence to assess how we traverse and perceive urban streetscapes. Many studies articulated that advanced data analytic techniques have potential to enhance the understanding about the interaction between individuals and the streetscape in a complex urban context. However, research on environment sensing still needs to pay an attention to bind, blend, and integrate the dynamic human behavior and the urban physical environment information. In this context, the research investigated a novel approach to predict preferred streetscape characteristics utilizing deep learning and geospatial techniques. This research addressed two major questions: to what extent does individual preference of streetscapes manifest in an urban setting, and to what extent are these preferences
are impacted by characteristics of the urban physical environment? We employed geotagged social media data and street view imagery. Furthermore, we applied two subsets of deep learning techniques: Natural Language Processing (NLP) and computer vision (CV). Infrastructure and transportation system development have long shaped our perceptions of time, space, and urban life. The recent emergence of technologies such as self-driving cars, big data, digital infrastructures, and urban sensor networks are constantly challenging our understanding of urban space by blurring the boundaries between the digital and physical worlds, shaping a different perception of urban streetscape for the pressing future.

Our interdisciplinary approach for 3D reconstruction integrates well-established techniques from computer graphics with shape grammar techniques borrowed from architecture but extended for 3-dimensional form. We took an iterative process exchanging information and workflow processes between the Immersive Visualization and CIVA lab team to improve the automatic 3D reconstruction process. To improve automatic 3D reconstructions of urban environments, we focused on four primary goals. 1.Integrating available foundational geospatial datasets and improving CAD workflows 2.Identifying and defining essential architectural grammars applicable to city-wide urban reconstruction, with roof typologies and grammar as an implementation example 3.Using the shape grammar approach to creating synthetic 3d models of
urban environments to help train deep learning models and improve the algorithm for extracting specific parameters related to the urban architectural grammar.

BRIEF
Development Artificial simulator testbeds that can realistically represent crash causation factors would enable safety researchers to evaluate new countermeasures. A simulator study may be necessary when evaluating a countermeasure that has not been implemented before or when sufficient after installation data does not exist. We propose to use naturalistic driving study data for crash events to develop, calibrate, and validate driving simulator testbeds that accurately replicate crash causation factors. In task 4, SHRP 2 NDS data will be used to generate realistic driving simulator testbeds for conducting human factor studies. Traffic crashes, especially at interchanges, are complex and highly dynamic, often involving multiple causal factors. Crash reconstructions offer
At a minimum, we will generate three representative testbeds of crashes that occur within an interchange footprint – one for daytime, one for night time, and one angle crash involving a left turning vehicle onto the freeway. Using a combination of match moving data extracted from the crash videos and other pertinent data from the SHRP 2 dataset, we will create interactive, 3D visualizations of NDS crashes. In developing these visualizations, we will take every reasonable measure to ensure the accuracy of the visualizations including benchmarking against the crash videos and relying on the time series trip data. These 3D visualizations will be similar to National Transportation Safety Board (NTSB) crash animations but with the added ability to interactively explore them from multiple perspectives using different display technologies
an opportunity to understand the factors involved and the sequence of precipitating events. The SHRP 2 data set provides an opportunity to generate an artificial but realistic testbed using accurate 3D modeling of interchange crashes. While the SHRP 2 dataset has videos from the vehicle involved in the crash, 3D visualization offers several advantages. First, they maintain privacy by removing personally identifiable information such vehicle model, unique location identifiers, etc. Second, 3D visualizations help to highlight certain visual parameters or perspectives by drawing a viewer’s attention to aspects that are the most important as compared to crash videos. Third, a 3D simulator testbed offers the opportunity to test human reaction to a variety of countermeasures, including safely testing connected and autonomous vehicle technologies.
Output
including virtual reality. The UMC team will lead task 4. The PIs have generated representative crashes for work zones using SHRP2 data as part of their previous FHWA BAA project. MSU and TTU partners will review the developed simulation testbeds and provide feedback. Anticipated deliverables: 1) Case studies and simulation test beds for interchange conditions, 2) A document explaining the procedures used to generate the test beds.

PROJECT TYPE Urban studies BRIEF
The project’s goal was to create a village in the Ramna botomul environment where people may experience Bangladeshi culture. Ramna Park is a large park and recreational area in the center of Dhaka, Bangladesh’s capital city. This park is one of Dhaka’s most attractive locations, with many trees and a lake in its center. Ramna botomul is called after a Banyan tree, which is recognized for important historical elements and the foundation of civilization, namely pohela boishakh. Pohela boishakh is the most important day for Bengalis in Bangladesh and India’s West Bengal, Assam, and Tripura. Because the first
day of the Bangla calendar is Pohela boishakh. Bengalis eagerly await the celebration of Pohela Boishakh throughout the year. As a result, the notion arose from the country’s rural environment. In Bangladesh, villages typically grow around a river for easy access to markets. As a result, a cottage appears along the river, surrounded by trees, where people of various ages converse and roam. The proposed project has the same goal in mind: to help individuals discover their own culture and ancestry.

BRIEF
Since August 2017, more than 0.7 million stateless Rohingya refugees — an ethnic Muslim minority population from Rakhine State – have entered Bangladesh to flee the Myanmar Army’s atrocities against humanity. To accommodate them, significant deforestation and hill cutting activities were carried out in Bangladesh’s Cox’s Bazar District (CBD). The main issue in CBD was that the bulk of the displaced people were living in cramped unplanned shelters creating unhealthy built environment (ISCG, 2019). Sustainable measures analysis is therefore needed to lessen the environmental impact on these Refugee shelters (Gassar & Cha, 2020). In this context, this research
presents a workflow whether different clusters have higher energy consumption rate and is there Significant correlation exist between different design variables and the energy performances. we proposed the framework, which is based on GIS, parametric simulation modeling (Rhino-Grasshopper-Ladybug Tools) combined with deep learning (ANN). To perform statistical analysis, we utilized correlation matrix, summarize within, Explanatory Regression analysis, and ordinary least squares.

BRIEF
When the matter of resilience came up during the conception period of this project, the thought of generating less resistance to natural forces occurred. The project, due to Its amphibious nature and circular shape, provides minimal resistance to flood water and wind flow. As the house floats In harmony with the level of water and Is hollow underneath, It lets the flood water run smoothly. Its fomi and planned openings allow strong wind flow to not put Intolerable pressure on the structure and provides adequate ventilation. Putting less opposition to natural currents allows It to stand tall In natural setting. The shape is derived primarily from a water lily, but also takes inspiration from the: traditional raft for floating and umbrella for shade and radial structure.
The project seeks a resolve that is familiar to the inhabitants and disaster resilient by design. It is designed based on sustainable principles - Local, Modular and Energy-Efficiency. Using recognizable architectural scheme and sustainable materials, reducing transportation, saving energy, favoring development of home-grown Industry and over the life cycle of the building, attaining goals of sustainable architecture follows these principles. The project is shaped to allow free wind flow and amphibious to survive flooding, thus the concept - Less resistance, More resilience.
`13eRola Lily’ is a solution for an ecoaffordable single-family house for the low-Income class of flood-prone areas In Bangladesh.
