Special Issue Information

Dear Colleagues,

Renewable energy is the fastest-growing energy source since the beginning of the century and the demand growth with the fast development in industrial and transportation sectors. In the industrial sector, biomass makes up approximately 98 percent of the renewable energy use, with nearly 60 percent derived from biomass wood, about 32 percent from biofuels, and nearly 7 percent from biomass waste. In the transportation sector, renewable fuels, such as ethanol and biodiesel, have increased significantly during the past decade. The ethanol transportation fuel is expected to be the fastest growing renewable energy type with an average annual rate of approximately 9.7 percent over the next 30 years. The International Conference on Innovations in Energy Engineering and Cleaner Production (IEECP) aims to investigate innovation applications and the last research in the areas of energy production, alternative and renewable energy supply, energy savings analysis, cleaner production, optimization of energy processes and the environmental impacts.

Last year, the IEECP Annual Conference was held virtually in Silicon Valley, San Francisco, California, USA, from 29–30 July, 2021. This year, the IEECP Annual Conference will take place virtually in Oxford, United Kingdom, from 21-22 July, 2022, and is being supported by Sustainability. We encourage the authors who have presented an article at IEECP’21&22 and who feel that their contribution is within the scope of interest of the journal Sustainability to apply via the following link: https://www.mdpi.com/user/manuscripts/upload/.

The selected authors will be asked to submit an original and essential extension of the IEECP paper, to be considered for publication no later than November 30th. More details can be found at https://www.mdpi.com/journal/sustainability/instructions#preparation. The accepted papers, after a normal process of peer review by experts in the field, will be published in Sustainability.

A case history of a community “La Cañada” in Huixquilucan, State of Mexico (19°19′02.81″ N, 99°22′23.21″ W, 3025 m above mean sea level), a village [...] Read more.
The social acceptance of introducing an improved and sustainable roofing material in multicultural communities in Mexico was addressed. A case history of a community “La Cañada” in Huixquilucan, State of Mexico (19°19′02.81″ N, 99°22′23.21″ W, 3025 m above mean sea level), a village very close to the eastern edge of Mexico City and representative of strong social and transcultural pressures similar to surrounding communities in Mexico City, is reported. The approach considered developing a double-layered roof to reduce the energy demand for space heating in this predominantly cold region, thus significantly contributing to indoor thermal comfort, reducing the need for cutting wood and helping to alleviate the accelerating impacts of deforestation in the area. Two parallel studies were used, whereby the then-current awareness levels of citizens and the factors impacting their commitment to energy sustainability were analysed using multicriteria social parameters, while the second study focused on the analysis of improved comfort when the proposed double roof was implemented, based on the feedback received from a pool of citizens who experienced living in the improved prototype dwellings. Results showed that while the level of awareness on energy efficiency was still low, the influence of media on their decisions and aspirations was strong and this could be constructively used to support the shift towards a more sustainable society and a “solar culture”. Moreover, the developed sustainable double-roof prototype has significantly improved indoor comfort and energy savings for heating, while demonstrating a fast and easy replicability potential in similar dwellings.

Third-generation thin-film solar cells based on CZTSSe are highly promising because of their excellent optoelectrical properties, earth-abundant, and non-toxicity of their constituent elements. In this work, the performance of CZTSSe-based solar cells with TiO2, CdS, and ZnSe as electron transporting materials (ETMs) was numerically investigated using the Solar Cell Capacitance Simulator (SCAPS). The effect of the active layer’s thickness and electron affinity, different buffer layers, and the contour plot of the operating temperature versus thickness of the CdS buffer layer were studied. The results show that the optimum power conversion efficiency for CdS, TiO2, and ZnSe, as the ETMs, is 23.16%, 23.13%, and 22.42%, respectively. Full article

The conversion of CO2 to low-carbon fuels using solar energy is considered an economically attractive and environmentally friendly route. The development of novel catalysts and the use of solar energy via photocatalysis are key to achieving the goal of chemically reducing CO2 under mild conditions. TiO2 is not very effective for the photocatalytic reduction of CO2 to low-carbon chemicals such as methanol (CH3OH). Thus, in this work, novel Cu2O/TiO2 heterojunctions that can effectively separate photogenerated electrons and holes were prepared for photocatalytic CO2-to-CH3OH. More visible light-active Cu2O in the Cu2O/TiO2 heterojunctions favors the formation of methanol under visible light irradiation. On the other hand, under UV-Vis irradiation for 6 h, the CH3OH yielded from the photocatalytic CO2-to-CH3OH by the Cu2O/TiO2 heterojunctions is 21.0–70.6 µmol/g-catalyst. In contrast, the yield of CH3OH decreases with an increase in the Cu2O fraction in the Cu2O/TiO2 heterojunctions. It seems that excess Cu2O in Cu2O/TiO2 heterojunctions may lead to less UV light exposure for the photocatalysts, and may decrease the conversion efficiency of CO2 to CH3OH. Full article

Photosynthesis is considered to be one of the promising areas of cheap and environmentally friendly energy. Photosynthesis involves the process of water oxidation with the formation of molecular oxygen and hydrogen as byproducts. The aim of the present article is to review the energy (light) phase of photosynthesis based on the published X-ray studies of photosystems I and II (PS-I and PS-II). Using modern ideas about semiconductors and biological semiconductor structures, the mechanisms of H+, O2↑, e generation from water are described. At the initial stage, PS II produces hydrogen peroxide from water as a result of the photoenzymatic reaction, which is oxidized in the active center of PS-II on the Mn4CaO5 cluster to form O2↑, H+, e. Mn4+ is reduced to Mn2+ and then oxidized to Mn4+ with the transfer of reducing the equivalents of PS-I. The electrons formed are transported to PS-I (P 700), where the electrochemical reaction of water decomposition takes place in a two-electrode electrolysis system with the formation of gaseous oxygen and hydrogen. The proposed functioning mechanisms of PS-I and PS-II can be used in the development of environmentally friendly technologies for the production of molecular hydrogen. Full article

Heritage buildings are significant historical and architecture added value, which requires deep and precise preliminary brainstorming when considering upgrading or retrofitting these valuable buildings. In this study, we opted to highlight some passive design architecture interventions to improve the thermal comfort and the required cooling energy for buildings. The Murabba Palace in Riyadh was selected as a case study. DesignBuilder software was used to evaluate the energy performance of ten passive architectural design alternatives throughout different seasons in an attempt to improve the energy performance and thermal comfort of heritage buildings. The ten passive design scenarios encompassed double low-E glass, double reflected glass, double low-E glass and double wall with an air gap, double low-E glass and double wall with thermal insulation, double low-E glass and double wall with lightweight thermal insulation, double low-E glass and double wall with sprayed foam insulation, double reflected glass and double wall with an air gap, double reflected glass and double wall with thermal insulation, double reflected glass and double wall with lightweight thermal insulation, and double reflected glass and double wall with sprayed foam insulation. The results show that using double low-E glass and applying a double wall with polystyrene thermal insulation can enhance the thermal comfort inside the building and reduce the energy performance and CO2 emissions to 17% and 9%, respectively.
