“…In order to evaluate the effect of the tunable phase transition temperature of the HPC-PAA composite hydrogel smart window on energy saving, a simplified single-room model was constructed and utilized for building energy simulation using EnergyPlus. EnergyPlus is a professional software developed by the Department of Energy (DOE), US, which is widely used to conduct whole-building energy simulation [45][46][47][48][49]. The physical specifications of the smart window, such as solar transmittance and reflectivity as well as thermal and dimensional parameters, were imported into the EnergyPlus model, and thus the monthly and annual energy consumptions were obtained.…”

Thermoresponsive hydrogels have been designed for smart windows to dynamically modulate solar radiation, but their inherent drawbacks of long response time and imperfectly matched phase transition temperature have limited their wide applications. This work reports a novel composite hydrogel consisting of hydroxypropyl cellulose, polyacrylic acid, and carbon quantum dots with intriguing features of tunable transition temperature and enhanced switching speed. The composite hydrogel demonstrated flexible tunability in transition temperature by controlling the hydrogen ion concentration and a fast response speed by dopping with carbon dots for efficient photothermal conversion. The building energy simulation was carried out to investigate the impacts of transition temperature variations and solar regulations on the space cooling/heating loads under different climate conditions, revealing the necessity of tunability of both transition temperature and solar transmittance in thermochromic smart windows. This novel design of thermochromic composite hydrogel provides insight into theoretical and experimental support for future adaptive building envelopes.

“…Furthermore, the bioclimatic design of vernacular architecture has been evaluated and quantified through energy simulations [66][67][68][69][70][71]. The modeling procedure in the OpenStudio application for SketchUp and the simulation using the EnergyPlus 8.6.0.software are common in the evaluation of energy consumption in buildings [39,[72][73][74][75][76][77][78][79] and in research related to natural ventilation [80,81]. The potential of the tool for climatic, thermal and hygrothermal studies is also the subject of study [82][83][84][85][86][87].…”

Within a context in which temperatures are increasing due to global warming, it is important to assess the capacity of buildings, old and modern, to respond to this new situation. Recent studies have highlighted the importance of understanding more about the thermal properties of traditional constructions. This study quantifies the impact of the high summer temperatures typical of the Mediterranean climate on traditional farmhouses in Eastern Almería (Spain). The study group of farmhouses was divided into three models representative of the different types of Eastern Almería vernacular architecture. Energy consumption in the three models was simulated using EnergyPlus. The three models were assessed in free-floating conditions. The window-to-wall ratio and U-factor values were studied in order to evaluate potential benefits in terms of energy efficiency. Outdoor and indoor temperatures were compared. Finally, an adaptive thermal comfort analysis was performed according to ASHRAE 55. Results highlight the ability of Eastern Almería farmhouses to mitigate extreme temperatures.

“…In order to simulate the energy consumption of the outpatient clinic and to optimize the impact of air conditioning energy efficiency ratio and photovoltaic variables on the energy consumption of the building, a geometric model of the outpatient building was created in this paper and modelled using Sketch Up software., which was refer to the previous research methods with some optimization (Feng et al, 2022;Bastos Porsani et al, 2023). The main method was to import existing CAD drawings into Sketch Up and then to obtain the geometric model of the whole building by means of a new Zone using commands such as stretch, move and copy.…”

With the rapid development of economy and urbanization in China, cities are expanding rapidly and more constructions are being built, then lead to the fast-growing part in urban residential energy consumption. In China’s hot summer and cold winter regions, many buildings are not centrally heated and commonly rely on electrical equipment such as air conditioners which are all energy-inefficient thermoregulation devices. In order to analyze the relationship between building energy consumption and the energy efficiency ratio (EER) of air conditioning and the area of photovoltaic (PV) on the roof, the influence of the building envelope on building energy consumption in hot summer and cold winter regions in China is clarified. This paper uses energy plus software to analyze the impact of different EER and PV area on building energy consumption using a typical case study of a public health upgrading project in the eastern part of the Wuxing district, Huzhou, Zhejiang province in China. The simulation results show that the factor that has a greater impact on the energy consumption of the health center in summer is the PV area parameter of the building compared to the performance parameters of the air conditioning equipment. The PV area parameter settings and air conditioning equipment performance adjustments are dependent on the actual situation and the comprehensive energy saving rate of the outpatient building for public health in the eastern part of Tai Wu Xing District can exceed 50%. Finally, an economic analysis of the carbon tax and input costs is carried out, and the best combination is of which 60% of the area covered by Longi Green PV panels and an air conditioning efficiency ratio of 4.87. The research result combines renewable energy and efficient equipment to achieve dual optimization of environmental and economic aspects of building energy consumption, while providing reference opinions on the comprehensive evaluation method of building energy consumption from the perspective of carbon tax.
