Special Issue Information

Dear Colleagues,

The latest IPCC report (Intergovernmental Panel on Climate Change, 2022) confirms the strong interactions of the natural, social and climate systems, and that human-induced climate change has caused widespread adverse impacts to nature and people.

It is clear that across sectors and regions, the most vulnerable people and systems are disproportionately affected, and climate extremes have led to irreversible impacts. The assessment underscores the importance of limiting global warming to 1.5°C if we are to achieve a fair, equitable and sustainable world. One of the key contributors to increasing worldwide energy consumption is the service sector, which covers all types of buildings with a wide range of HVAC systems. The global energy consumption of the service sector has increased by 295 Mtoe in 2018 compared to 2000 levels, and with this trend, the sector would consume a further 323 Mtoe by 2040.

The increase in the global temperatures and carbon emissions, accompanied by recent geo-political developments, has triggered drastic measures by most governments to reduce the dependency of energy in buildings on fossil fuels.

This Special Issue of Sustainability, “Sustainable Development of Thermal Comfort and Energy-Savings and Storage of Green Buildings”, is focused on new methodologies, low-carbon strategies and technologies, energy storage to reduce the fossil fuel-reliance of heating and cooling in buildings. We invite researchers to contribute original research articles as well as review articles that will stimulate the continuing efforts to understand the recent advances and innovation in these research fields. Manuscripts combining experimental implementation with theoretical calculations and technoeconomic assessment are also welcome. 

Themes and topics for this Special Issue include the following:

  • Energy storage to low-carbon heating and cooling in buildings;
  • Passive energy transition to reduce demand and fossil fuel dependency in buildings;
  • Occupants’ comfort, health and wellbeing in a changing climate;
  • Energy flexibility and resilience in the built environment;
  • Advanced materials to face with thermal comfort.

The energy consumption in buildings is high currently, leading to the development of the building envelope with phase change material (PCM), while the application of PCMs to the building envelope has the potential to effectively regulate the temperature variations in the inner surfaces of walls. Eutectic PCM consists of lauric acid, myristic acid, and stearic acid (LA-MA-SA) and was synthesized first, while expanded graphite (EG) and diamote (DE) were used as additives. LA-MA-SA/10 wt.% EG/10 wt.% DE composite PCM was synthesized via the impregnation method; then, the phase change layer was compressed and formed under a pressure of 10 MPa. The sandwich phase change gypsum board was built with three layers, considering the phase change layer on the outside, middle and indoor sides of the board, respectively. The thermal responses of sandwich phase change gypsum boards were considered under various radiation conditions at controlled temperatures of 37 °C, 40 °C, 45 °C and 50 °C. The results indicated that the gypsum board with the addition of 16.7 wt.% composite PCMs showed a better relative time duration of thermal comfort in comparison with pure gypsum board. The indoor heating rate slowed down, and the environmental temperature fluctuation was within a smaller range, because of the latent heat of the phase change gypsum board. Comparing the phase change gypsum boards at different interlayer positions, we found that the phase change gypsum board with an interlayer on the indoor side shows better thermal performance and a relatively longer time duration of thermal comfort, e.g., when the setting temperatures were 37 °C, 40 °C, 45 °C and 50 °C, respectively, the relative time durations of the thermal comfort of the sandwich phase change gypsum board were 4825 s, 3160 s, 1980 s and 1710 s. This study provides insights into the thermoregulation performance of phase change walls, where the utilization of a PCM in a wall can increase thermal capacity and enhance the inner-zone thermal comfort. The findings can provide guidelines for phase change walls to ensure sustainable practices in the energy savings of buildings. Full article

With the rapid advancement of rural revitalization in China, protecting regional culture and construction techniques of traditional ethnic groups, while incorporating green energy-saving concepts, has become increasingly vital. With Sware ITES2023 as the simulation tool, this article conducts a comparative study on the green building technology and thermal comfort of traditional Tibetan residential houses in Songpan, Sichuan Province, and the new residential houses that villagers have incessantly renovated and built in the past two decades, thus demonstrating the advantages and disadvantages of traditional houses and newly-built houses in terms of green building technology elements, such as stone and wood structures, roof floors, walls, doors, and windows, therefore developing an optimized design scheme, which includes the eastern direction of a building’s orientation, concrete frame and wooden structure, brick wall and stone masonry, and optimized door and window size selection. This scheme will improve indoor thermal comfort by two to three times by calculation. Through preliminary simulation and deduction, the optimized design scheme combines traditional architectural culture and ethnic characteristics with green and energy-saving concepts. This provides a design paradigm that can be promoted and popularized for the construction of residential buildings in high-altitude ethnic areas of western Sichuan and also lays the foundation for future protection and research of traditional residential architecture.
