This study aims to assess individuals’ thermal responses under various high-temperature combinations resembling those encountered in the spinning workshop. Forty students were recruited as participants and exposed to 112 state points within a controlled climate chamber. These conditions encompassed diverse high-temperature combinations, comprising four temperature levels (29 °C, 32 °C, 35 °C, and 40 °C), seven humidity levels (30%, 40%, 50%, 55%, 60%, 65%, and 70%), and four air velocity levels (0, 0.1, 0.3, and 0.5 m/s). Participants donned single-layer clothing with a thermal resistance of 0.6 clo, and their subjective evaluations were collected via questionnaires. The study confirms that the GB/T 50481 guidelines for workshop temperature appear to be reasonable, considering the low thermal expectation and adaptation of workers. However, nearly 100% of the participants deemed temperatures surpassing 38 °Cwithin the spinning workshop as unacceptable, with approximately 80% of participants categorizing it as distinctly unacceptable. Consequently, it is recommended that the GB/T 50481 standards be extended to explicitly declare temperatures above 38 °C within the spinning workshop as unacceptable. This study lays a robust foundation for forthcoming research concerning high-temperature conditions within spinning workshops.KEYWORDS: Spinning workshoppredicted mean vote (PMV)thermal sensation vote (TSV)thermal comfort vote (TCV)thermal acceptability vote (TAV) Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingWe would like to thank China National Textile and Apparel Council (No. 2021053).","PeriodicalId":46184,"journal":{"name":"Advances in Building Energy Research","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136033556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The huge potential that can be exploited in terms of energy savings is evident, mainly regarding the HVAC system refurbishment. From literature emerges that there are poor systematic analyses concerning all the possible HVAC retrofit scenarios, considering solutions currently on the market or renewable sources. To fill the research gap pointed out, the present paper proposes a rigorous analysis of the possible generation subsystems available on the market that can be implemented in an HVAC retrofit for a hospital. A real case study of 88,000 m3, represented by a hospital in southern Italy, has been used. Different technologies, such as the photovoltaic system, electric heat pump, absorption heat pump driven by solar energy, cogeneration are analysed from the energy and environmental point of view, with the introduction of the Imported Energy Level Index (IELI). The best retrofit measures is the installation of an absorption heat pump driven by solar thermal collectors and cogeneration, with a primary energy saving of 20%. Considering the installation of a heat recovery unit, the saving is up to 43%.KEYWORDS: Energy savingHVAC hospital building refurbishmentcarbon dioxide emission reduction‌renewable sourcesImported Energy Level Index NomenclatureCO2=Carbon dioxide emission [kgCO2/y]E=Energy [GWh/y]IELI=Imported Energy Level Index [%]PES=Primary Energy Saving [%] Greek symbolsα=Emission factor for electricity generation [gCO2/kWhel]β=Emission factors for natural gas [kgCO2/kWhEp]η=Efficiency [-], [%]Δ=Percent variation with respect to base case [%] SuperscriptAHP=Absorption Heat PumpAHU=Air Handling UnitB=BoilerBMS=Building Management SystemBS=Base CaseCHP=Combined Heat and PowerDHW=Domestic Hot WaterEHP=Electric Heat PumpE-L=Electric LoadsFC=Fan-coilfg=fed into the gridHWST=Hot Water Storage TankISPRA=Istituto Superiore per la Protezione e la Ricerca AmbientalePAC=Proposed Alternative CasePP=Power PlantPV=Photovoltaic systemR=RadiatorsSTC=Solar Thermal Collectorsuos=Used on-site Subscriptco=Coolingel=Electricp=Primary energyth=Thermal AcronymsAHP=Absorption Heat PumpAHU=Air Handling UnitB=BoilerBS=Base CaseCHP=Combined Heat and PowerDHW=Domestic Hot WaterEHP=Electric Heat PumpFC=Fan-coilHWST=Hot Water Storage TankPP=Power PlantPV=Photovoltaic systemR=RadiatorsSTC=Solar Thermal CollectorsVFD=Variable Frequency DriveVP=Variable PitchDisclosure statementNo potential conflict of interest was reported by the author(s).","PeriodicalId":46184,"journal":{"name":"Advances in Building Energy Research","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136210596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reduce it, it is necessary to identify the factors contributing to commercial building energy usage. Towards this, we studied the importance of various building features and their contributions on cooling energy, using two datasets of Commercial Building Energy Consumption Survey (CBECS) 2018 and 2012. For this, Shapash, an explainable artificial intelligence technique, was used, with Random Forest, to predict the cooling energy usage intensity (EUI). The two most important features for 2018 are cooling degree days and principal building activity, while cooling degree days and cooling percentage were for 2012 with 54.79% and 33.46% contributions of the total consumption respectively. The comparison of feature importance indicated that cooling degree days are the topmost important feature impacting cooling EUI and have a more significant contribution of 34.29% for 2018 and 19.68% for 2012. Overall, the most important features impacting cooling EUI were cooling degree days, principle building activity, cooling percentage and total hours open per week. The results from this study provide insights into the most significant factors influencing energy consumption and help in developing strategies for reducing it.KEYWORDS: Explainable artificial intelligence (XAI)Shapashcooling energy usageenergy efficiencyrandom forestCBECSfeature importance Disclosure statementNo potential conflict of interest was reported by the author(s).","PeriodicalId":46184,"journal":{"name":"Advances in Building Energy Research","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136295345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using experimental data and a sensitivity technique, the thermal efficiency of both the systems were evaluated. During the experiments conducted for cooling period in June 2022, the data for six-day operation were collected and the coefficient of performance of both the systems were evaluated. Notably, the GSHP system exhibited an average cooling capacity of 10 to 15 kW, whereas the ASAC maintained a range of 9 and 13 kW. The coefficient of performance (COP) for the GSHP system was obtained as 3.8, while the ASAC system COP was 2.9. The results indicate that the use of GSHP system results in an energy-saving of 10–40% in comparison to the ASAC system. Moreover, the present study included uncertainty and propagation analyses, along with sensitivity evaluations, with the objective of identifying the most influencing parameter on the derived parameters. Sensitivity analysis indicates outlet temperature of air from the evaporator is the most influencing parameter for the performance of both the systems.KEYWORDS: Ground-source heat pumpair-source air-conditioning systemenergy-savingsuncertainty and sensitivity analysiscooling mode operation AcknowledgementsThe experimental facilities for this research were provided by the Department of Architecture and Planning at IIT Roorkee supported by the Engineering and Physics Science Research Council (EPSRC) of the United Kingdom (EP/R00861) and the Government of India (ZED-i).

In this perspective, using the water bath model and particle image velocimetry, an experimental study of the relationship between fluid velocity caused by buoyancy-driven natural ventilation in a building with single-sided and cross ventilation has been conducted. A case study building with a jointed atrium has been considered for the six initial conditions tests. In the test model which has two low-level inlet openings, fluid velocity in single-sided ventilation mode was meaningfully higher than in cross-ventilation mode, ranging from 18% to 32%. In contrast, by changing the position of the windows to higher levels, cross ventilation creates a flow with 28% higher velocity. Analyzing velocity data demonstrates that, in all tests, the air change rate caused by buoyancy force in cross ventilation mode is more than in single-sided one. Furthermore, in the tests with two high-level openings acting as outlet openings, by opening both sides’ windows in the building, the air change rate increases significantly by 71.75%.KEYWORDS: Buoyancy-driven natural ventilationwater bath modelparticle image velocimetryatrium‌air change rate Disclosure statementNo potential conflict of interest was reported by the author(s).","PeriodicalId":46184,"journal":{"name":"Advances in Building Energy Research","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136279611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a baseline study in controlled environments demonstrating the combined effect of multiple environmental variable has yet to be available. In this context, this study presents the results of controlled climate-chamber-based thermal comfort experiments performed with 16 acclimatized subjects. Each subject underwent 140 test conditions covering 20–40°C Ta, 30–70% RH, and 0.25–2.0 m/s Va while performing a sedentary activity, yielding 8360 valid subjective responses. The study yielded a Tn of 29.3°C in terms of Ta, while the comfort temperature varied from 25.7 to 32.9°C (Ta). The effect of RH and Va on thermal sensation, comfort and preferences are established. An empirical reformulation of the Tropical Summer Index with thermal sensation and comfort votes is presented. A comparative analysis of the baseline thermal comfort limits with the adaptive comfort limits established by various field studies in the sub-tropical region is presented.
