The relationship between "coping" and "resilience" increasingly features in academic, policy and practical discussions on adaptation to climate change in urban areas. This paper examines this relationship in the context of households in "extreme poverty" in the city of Khulna, Bangladesh. It draws on a quantitative data set based on 550 household interviews in low-income and informal settlements that identified the extent of the underlying drivers of vulnerability in this setting, including very low income, inadequate shelter, poor nutritional status and limited physical assets. A series of focus groups were used to explore the ways in which physical hazards have interacted with this underlying vulnerability, as a means to understand the potential impacts of climate change on this particular group of urban residents. These outcomes include frequent water-logging, the destruction of houses and disruption to the provision of basic services. The main focus of the paper is on describing the practices of low-income urban residents in responding to climate-related shocks and stresses, placing these in a particular political context, and drawing lessons for urban policies in Bangladesh and elsewhere. A wide range of specific adaptation-related activities can be identified, which can be grouped into three main categories-individual, communal and institutional. The paper examines the extent to which institutional actions are merely "coping"-or whether they create the conditions in which individuals and households can strengthen their own long-term resilience. Similarly, it examines the extent to which individual and communal responses are merely "coping"-or whether they have the potential to generate broader political change that strengthens the position of marginalized groups in the city.

This paper presents the application of Internet of Things (IoT) Technology and Building Energy Management System (BEMS) within the Marylebone Campus of the University of Westminster, located in central London, to improve the environmental performance of the existing building as well as enhance the learning experience on energy and sustainability. Sixty IoT sensors connected to minicomputers were planned to be deployed within three floors of the building to continuously measure the real-time environmental parameters, such as dry-bulb temperature, relative humidity, illuminance level, carbon dioxide, and sound levels. Experimental workshops were also arranged with undergraduate and post-graduate students at their classrooms using IoT sensors, portable Bluetooth sensors and online questionnaires to increase awareness of the effect of environmental and behavioural changes on energy saving through real-time visualisation. Users’ subjective feedback on their workplace was also collected through Post Occupancy Evaluation (POE) questionnaire surveys. The results show the effectiveness of IoT systems and BEMS in supplying the building users and management with high-resolution, low-cost data acquisition systems highlighting the existing challenges and future scopes. The study also documents the process and the improvement in students’ awareness of environmental and energy performance of their building through IoT data visualizations and POE.

Applications of the Internet of Things (IoT) are rapidly utilized in smart buildings and smart cities to reduce energy consumption. This advancement has caused a knowledge gap in applying IoT effectively by experts in the built environment to achieve energy efficiency. The study aims to provide an extensive review of IoT applications for energy savings in buildings and cities. This study contributes to the field of IoT by guiding and supporting built environment experts to utilize IoT technologies. This paper performed a thorough study using a systematic review that covered an overview of IoT concepts, models, applications, trends and challenges that can be encountered in the built environment. The findings indicated limitations in developing IoT strategies in buildings and cities by professionals in this field due to insufficient comprehension of technologies and their applied methods. Additionally, the study found an indefinite implementation and constraints on using IoT when integrated into the built environment. Finally, the study provides critical arguments and the next steps to effectively utilize IoT in terms of energy efficiency.
