Authors:   IIT Kharagpur, Kharagpur, India, Singh Harshal , Ramgopal Maddali ,   IIT Kharagpur, Kharagpur, India
Published: May 2024

This study examines optimal operation strategies for mixed-mode buildings located in 8 tropical Indian cities. In order to evaluate the potential for mixed-mode operation, a small, single storey building with provision for natural ventilation (NV) is considered. The building performance is simulated using OpenStudio-EnergyPlus. EnergyPlus Typical Meteorological Year (TMY) data is used for generating the results. Depending upon the predicted inside conditions, decisions are taken whether to operate the building in non-air conditioned mode or air conditioned mode. PMV-PPD based thermal comfort model is used when the building is operated in air conditioned mode, while suitable adaptive thermal comfort model is used when the building is operated in non- air conditioned mode. An algorithm for optimal mixed-mode operation is developed, utilizing simulation data to guide window usage and HVAC systems. The algorithm enables users to input location, date, and time to determine whether to keep windows open or closed and whether to use mechanical cooling or heating systems. Results show that mixed-mode operation has a huge potential for saving energy without sacrificing thermal comfort.

Hotels with their high energy demand and reliance on air-conditioning present significant design challenges. The paper draws upon occupancy patterns, guest surveys and energy use in built precedents to conduct detailed research on indoor and outdoor design strategies that balance guest comfort with minimal energy usage. These combine passive and mixed-mode approaches that invite protected use of outdoor and transitional spaces and a courtyard. Balconies feature elements such as jaalis, optimized facades, ceiling fans, and misting for comfort. Findings from extensive analytical studies show that use of non-renewable energy can be reduced by 70% while thermal comfort conditions in and around the hotel premises can be improved. The final design offers an attractive, immersive, and energy-efficient experience to guests while providing cost-saving options for hoteliers. It sets an example for future hotel designs in similar urban settings, inspiring sustainability in architecture and energy efficiency.

In recent years, the city of Mumbai has been experiencing the pressing challenge of urban heat islands, affecting the thermal comfort of its high-density urban environment, impacting both air and surface temperatures. The Intergovernmental Panel on Climate Change (IPCC) projected that climate change would adversely affect 27 million people in Mumbai (6th assessment report). Understanding the intricate relationship between the built environment and its influence on microclimates and thermal comfort was imperative for creating climate-sensitive designs. This paper investigated the role of urban morphology in improving the thermal comfort of a typical neighborhood in Mumbai. The analysis was based on simulations conducted using ENVI-met, a 3D urban climate modeling tool. The research aimed to comprehend how open spaces, aspect ratio, setbacks, and plot boundary conditions within the neighborhood affected outdoor thermal comfort. The objective was to underscore the significance of urban designers and planners in assessing the impact of built environments on microclimates and leveraging microclimatic insights for the design of public spaces. Air temperature, relative humidity, wind speed, and mean radiant temperature were measured at 15 locations within the neighborhood, Matunga east, and its primary street in February 2023. The recorded data were used to validate the Envi-Met model . Two distinct scales were analyzed: neighborhood-level and plot-level iterations. Neighborhood-level iterations focused on block-level modifications, while plot-level iterations examined street and boundary conditions. Each iteration was evaluated using EnviMet to assess changes in thermal conditions relative to the current site conditions (Base case). The analyses were conducted for the critical summer month (May). The study ultimately revealed that the introduction of road networks in prevailing wind directions and the incorporation of green open spaces within the urban fabric could reduce overall heat stress duration from 12 hours to 6 hours. Smaller-scale interventions, such as 50% porous pavements and strategically placed trees, also yielded positive outcomes. This research aspired to provide urban planners with a comprehensive framework that integrated outdoor thermal comfort as a pivotal aspect in the design of future urban landscapes.

In India, population growth, demand for housing, and rapid urbanisation have led to higher energy consumption in the building sector. According to the Government of India report, 80% of the buildings that will exist by 2050 are yet to be constructed and a larger percentage is contributed by the housing sector, the population using affordable housing is higher compared to other developed countries. The occupants tend to achieve the desired level of thermal comfort by personal adjustments and mechanical means. Using energy-intensive methods for comfort is not feasible for a country, like India, with a low-energy economy. This study analyses indoor thermal comfort in low income group housing with respect to the building materials and openings used. Two typologies of low income housing were identified - a row housing constructed using conventional materials and a vertical stacking multi-dwelling constructed using Laurie Baker’s sustainable construction technology. The first section of the study explores the current scenario of housing based on a thermal comfort field study to understand the current scenario by questionnaire survey and onsite measurements (following ASHRAE class II protocol) and a detailed analysis of the results from the computed data. The second part of the study is software simulation of the existing case with different approaches to improve thermal comfort using design builder simulation. And analysing the results to understand the improvement in indoor thermal comfort with respect to the existing model. From the results, it can be concluded that building material with higher thermal mass can cause a significant reduction in indoor temperatures and PMV thus improving indoor thermal comfort. Passive design strategies to improve indoor thermal comfort with respect to envelope material and openings for future projects at the study area under the low-income housing category, without breaking the concern of cost-effectiveness in affordability, are developed.

The study is focused on the thermal performance analysis of a thermoelectric radiant heating panel (TERHP) system in a test chamber for cold climatic conditions. Three radiant panels with eight thermoelectric modules (TEM) each are installed on the three different walls of the study chamber to evaluate the performance of the panels to achieve the thermal comfort temperature inside the chamber of 1.2 × 1.2 × 2 m. All TEMs in a single TE panel of size 0.75 x 0.50 m are attached in a triangular arrangement to obtain a uniform temperature. The water block is used as a heat sink to maintain the temperature difference between the cold and hot sides of TEMs. The water circulation circuit with the "I" configuration has been used. Hot water at a constant temperature is supplied to the water block, and cold water obtained at the outlet is collected and circulated back after thermoregulation in a closed loop. The experiment is conducted by supplying inlet water at 18°C and applying operating voltages to the TERHP system of 12 V, 16 V, and 20 V. The surface temperature of panels, mean radiant temperature, operative temperature, air temperature, heating capacity, and coefficient of performance are measured on these inputs.

This study evaluated the impact of different weather stations on building energy simulations (BES) concerning local environmental factors. The investigation focused on eight distinct weather stations in São Paulo, Brazil, comparing their data's influence on thermal autonomy and cooling load in a low-income dwelling. Employing EnergyPlus for computational simulations, the outcomes were compared against the surrounding urban fabric and natural coverage indexes. The analysis revealed noteworthy differences between the weather stations with more natural vegetation and those densely urbanized. These disparities were particularly pronounced, with differences of up to fivefold observed in cooling degree hours (CDH) between these locations. Consequently, these discrepancies in weather inputs impacted cooling load predictions, portraying urbanized regions with markedly elevated cooling requirements relative to the more naturally covered areas. Regarding the correlation between the surrounding indexes, site coverage and vegetation cover were more impactful in predicting thermal autonomy and cooling load.

Ireland's ambitious goal of achieving net-zero emissions by 2050 necessitates significant reductions in operational emissions from its building sector, prompting the government to target the energy retrofitting of a quarter of its building stock by 2030. However, retrofitting historic buildings poses substantial challenges stemming from concerns related to architectural conservation, cost, and technical complexities. In this context, focusing specifically on addressing heat loss through single-glazed historic windows, this study revisits traditional heat loss mitigation techniques that were once prevalent in historic buildings but have since fallen out of common use. With in-situ tests, we investigate the thermal performance of curtains, blinds and shutters on single-glazed wooden sash and case historic windows. We present variations in heat loss through the window and its associated thermal comfort in response to each strategy. Test results show significant heat loss reduction from a combination of traditional strategies which is on par with secondary glazing. These strategies offer viable solutions for energy efficiency and thermal comfort in historic buildings without major interventions on the protected historic fabric.

In India, the ill effects of a poor indoor environment are seen as the cause of about 2 million premature deaths per year, wherein 44% are due to pneumonia, 54% from chronic obstructive pulmonary disease (COPD), and 2% from lung cancer. Conventional studies typically take lesser consideration of indoor occupancy than would be found in real surroundings. These studies often evolve in artificial conditions, which lack authenticity. This work uses field research and a data-driven approach to assess contaminants in inhabited indoor spaces, such as carbon dioxide (CO2) and particulate matter (PM2.5) along with indoor climate measurements of Indoor Operative Temperature (IOT), Relative Humidity (RH), and air velocity. This paper reports the findings of a pilot field study carried out to understand the effect of CO2, IOT, PM2.5, RH, age, sex, general health condition, and perception of odours on occupant’s perception of IAQ and perceived thermal comfort, during the summer monsoon season in the composite climate of Delhi. Participants were asked to rate their perceived thermal comfort on standardized scales and provide PIAQ votes based on their satisfaction with indoor air quality. Data analysis included correlation analyses and multiple regression modelling. Our findings reveal a statistically significant inverse relationship between perceived Indoor Air Quality (PIAQ) votes and perceived thermal comfort. Building occupants who rated the indoor air quality more favourably (higher PIAQ votes) tended to report lower levels of perceived thermal comfort, while those who expressed dissatisfaction with indoor air quality reported higher thermal comfort levels.

In a context of global warming, heat waves are predicted to become more frequent and intense along the next decades. The elderly are among the most vulnerable groups to extreme heat due to their dysfunctional thermoregulatory mechanisms and propensity to illnesses. This research aims to assess impacts of urban heating on this demographic group, using the ENVI-met V.5 model to simulate microclimatic conditions at a representative neighborhood in the city of Sao Paulo, adopting the PET Index as a comparative variable. Results obtained from historical climate data are compared to those of projections according to the Intergovernmental Panel on Climate Change (IPCC) Representative Concentration Pathways (RCP) 8.5 scenario. After the realization of impacts, urban surfaces albedo modifications were tested, in search for the most effective mitigating adaptations. Results obtained until now show that increasing average albedo of built surfaces can help moderate rising temperatures, but would not be enough to compensate the increase predicted for the coming decades.

Driven by climate change, especially the increase in the occurrence of heat waves around the world, this work has the objective of systematizing the municipal climate adaptation plans collected according to the criteria outlined in the document Measuring Benefits of Urban Heat Adaptation published in March 2021 by the C40 Group of Major Cities for Climate Leadership. The main results show that out of 259 documents raised, only 154 effectively correspond to Climate Adaptation Plans, as most of these documents are American. Among the actions proposed by C40, mention of mitigation is present in all documents, through the guideline aimed at reducing greenhouse gas emissions. The second most mentioned action refers to green infrastructure at 75%. However, it is important to highlight two other actions: heatwave response planning and development of cooling places are mentioned in only 44% and 34% of the analysed documents respectively. In particular, actions related to cooling places, such as grey built-up structures and water features appear only in more recent plans, mainly since 2015. Therefore, due to the current demand the readaptation of public spaces through the design of a network of refrigeration spaces distributed throughout the city is urgent.

Office workers use a variety of adaptive opportunities to regulate their indoor thermal environment. The behavioural adaptations such as window opening, clothing adjustments, and use of heating/cooling are important factors for adaptive thermal comfort. It is well-known that they are the most important contributors in the adaptive thermal comfort model. Thus, if we understand the behavioural adaptation properly, we can explain the mechanism of the adaptive model. The indoor thermal environment is often adjusted using the air conditioning in Japanese office buildings to improve thermal comfort and productivity. Thus, it is necessary to conduct research on the behavioural adaptation in the offices because the occupant behaviour is different from behaviour in dwellings. In order to record the seasonal differences in behavioural adaptation and to develop an adaptive algorithm for Japanese offices, we measured temperatures in seven office buildings and conducted the thermal comfort and occupant behaviour survey for over a year. We collected 1,228 samples. The proportion of ‘open window’ is significantly high in the free running and air conditioned modes. The behavioural adaptation is related to the outdoor air temperature. The clothing adjustments, heating and cooling use can be predicted by regression equations. These findings can be applied to building thermal simulation to predict the behavioural adaptation and energy use in office buildings.

Nhận thức quá trình và các nhân tố đóng góp vào tăng trưởng kinh tế là mục tiêu cao nhất của kinh tế học. Lý thuyết tăng trưởng kinh tế đã trải qua một lịch sử phát triển hơn 200 năm nếu chúng ta xem lý thuyết kinh tế chính trị cổ điển như điểm xuất phát, trong khi đó lý thuyết tăng trưởng tân cổ điển chỉ mới hình thành sau Chiến tranh thế giới thứ hai nhưng đã mang nhiều đóng góp vào lý thuyết tăng trưởng. Đó là lý do mà phần lớn các nghiên cứu tổng quan tập trung vào những mô hình tăng trưởng của trường phái này. Tuy nhiên, đáng chú ý là những nghiên cứu tổng quan trước chỉ nhấn mạnh các mô hình lý thuyết và những khám phá thực nghiệm chính yếu nhưng không làm rõ sự tiến hóa trong lý thuyết tăng trưởng tân cổ điển. Đây là khoảng trống mà nghiên cứu này hướng đến.

Analyzing the Portrayal of Political Leadership in Leading Pakistani News Channels : A Critical Analysis
Authors:   Doctoral Fellow, College of Journalism and Communication, University of Florida USA., Sohail Rana Babar
Published: May 2024

This study focuses on the framing theory as a lens to analyze the coverage and frames of political parties by two prominent news channels, Dunya News and Geo News. A comprehensive content analysis spanning over three months was conducted to assess the frequency, story types, frames, and tone of news coverage related to political leaders from 1st Sep 2023 to 20th Dec 2023 through purposive sampling. For this purpose, five themes, party manifesto, and plans, leader’s character, past performance of the party, voting worth, bias, and victimization were designed to explore the study’s objectives. The findings indicate a notable disparity in the salience given to political parties, with both news channels showing a higher emphasis on PMLN compared to PTI and PPP. Furthermore, the results reveal that Nawaz Sharif, received more favorable coverage from both news channels, followed by Imran Khan. Bilawal Bhutto Zardari receives comparable coverage to Imran Khan on Dunya News but notably less on Geo News. Additionally, the majority of the stance from these news channels leans in favor of PMLN leader Nawaz Sharif, while PTI leader Imran Khan tends to receive a more negative stance across both channels. A frames-wise analysis uncovers that Dunya News provides a more diverse range of perspectives when portraying political leaders, encompassing frames such as party manifesto, party previous performance, and voting worth, in contrast to Geo News, which maintains a more consistent distribution of emphasis across different frames. Findings also revealed that Nawaz Sharif’s frames prominently centered on the manifesto category. On the other hand, Imran Khan received coverage under the attributes of leaders’ character while party performance was a common attribute covered related to politicians.

The findings have shown that government social distancing policies have a negative impact, whereas government containment, health response, and income assistance programs are likely to contribute to a positive market reaction by increasing investor confidence and lowering the disease’s negative economic impacts. Regression analysis shows that the SI has a negative relationship with stock return and containment and mitigation and economic support health index has positive relationship with stock return, but they have no effect on movement of return as they are insignificant. However, the results imply that COVID-19 confirmed cases and the exchange rate have a significant negative impact on the movement of the stock return. The findings have important policy implications because they show that government intervention policies have significant economic effects.
