“…Accordingly, controlling “air temperature” and “air velocity” achieves an acceptable thermal comfort in kitchen (cooking) areas (Zainuddin et al, 2014). In hot and humid environments, typically the SET index was employed to determine the occupant thermal comfort when performing CFD simulations (Han et al, 2007; Hussin et al, 2014; Malek et al, 2015; Damian, 2017; Nazarian et al, 2017; Shetty et al, 2016).…”

In an indoor kitchen environment, proper installation of supplying air system is essential for maintaining optimal human thermal comfort level. Current thermal comfort investigation has been accomplished during "various cooking periods (breakfast, lunch, snacks, dinner)" inside the air-conditioned kitchen environment of railway pantry car in India. The study goals to improve thermal comfort inside the pantry kitchen by implementing proper installation of the supply air system. A field experiment and computational fluid dynamics approach has been carried out during the summer season. Also, standard effective temperature (SET) index was utilized to determine the thermal comfort status. Three proposed design modified cases of pantry cars (based on supplying air system concepts) have been executed followed by validation and comparison with the existing case model. Results revealed modified Case III as a better design concept (indicating better air supply circulation and temperature decrease at the desired location) compared to the existing and other two proposed cases. Simultaneously, the SET index range was 26.5-28.6°C; indicating "comfortable thermal sensation throughout the cooking period." This study's outcomes suggest improvements in thermal comfort and energy savings of "airconditioned" pantry car kitchens in "Indian Railways" that could be referred directly.

“…In China also at the hot and humid climate for occupant's thermal comfort inside the residence same SET index was used [29]. Accordingly, in Singapore Shetty et al [30] have researched hot and moist environments using energy-efficient fans. Used the SET index based on the "ASHRAE 55" standard to assess the thermal comfort of occupants in the building for energysaving and compared it to field measurement data [30].…”

There are ample literature studies available, focusing on hot-humid built environment, which have achieved an increase in thermal comfort conditions by proper installation of ventilation-systems. The present thermal comfort study has been carried out in the kitchen environment of a non-air-conditioned railway pantry car in Indian Railways. The purpose is to enhance thermal comfort level under the currently applied ventilation system inside the kitchen of pantry car by determining the standard effective temperature (SET) index. During the summer and winter seasons, a field study was carried out to obtain the value of air temperature, globe temperature, relative humidity, and air velocity inside the pantry car for estimation of the SET index. A computational fluid dynamics (CFD) analysis was used to obtain a better-modified case model of the pantry car kitchen for the improvement of thermal comfort. The design interventions for the pantry car kitchen were created, with emphasis on increasing energy efficiency based on low-power consumption air ventilation system. The study results indicated that, modified case-I model has a better ventilation design concept as compare to the existing and other models, which increased the air velocity and significantly decreased the air temperature inside the kitchen of pantry car at all cooking periods. A value of SET (28.6–30℃) was found with a comfortable thermal sensation within all cooking periods, which is better for the pantry car workers. This finding suggests a sustainable improvement in the thermal environment of the "non-air-conditioned" pantry car kitchen in the Indian Railways, which can be applied immediately.

“…Hence, designing a sustainable building does not mean that high cost of the technology implementation is in the picture but it is more about selecting the right technologies that can cater well for the building's condition (Nazi et al, 2015). Shetty et al (2016) examined to pick up bits of knowledge on the utilization of individual fans regarding temperature, time and different components and information are contrasted and the SET (Standard Effective Temperature). The proposed work recommends rules on fusing tenant inclinations in a decentralized structure for better warm solace and enhanced vitality funds in existing cooled structures.…”

“…The proposed work recommends rules on fusing tenant inclinations in a decentralized structure for better warm solace and enhanced vitality funds in existing cooled structures. Beginning outcomes uncover that identifying the low-action and high-movement breaks is significant to comprehend the tenant inclinations for the entire working day (Shetty et al, 2016). Kontes et al (2017) have defined an experimental simulation protocol involving two office buildings; the buildings have contrasting geometrical and construction characteristics as well as different building services systems for meeting heating and cooling demands, occupant thermal comfort is estimated using the Fanger index as defined in ISO 7730.…”

The growing demands for energy usage and better indoor environment quality have motivated in searching for the modern solutions on energy efficiency, electricity consumption and conservation in buildings. The building sector being the largest consumer of electric energy represents a major potential contributor for reducing energy consumption. For such purpose, Building Energy Management System (BEMS) is considered as the latest idea of energy. In this study an attempt is made to measure and evaluate the existing indoor comfort parameters which is focusing on the College of Art, Mosul University, Iraq. The building case studies used in this studydemonstrated how the strategy can be emulated. The physical parameter conditions are then compared with the current ASHRAE Standard-55. These strategies provide practical implications for facility managers to engage the building occupants in working together to achieve energy reductions.
