Special Issue Information

Dear Colleagues,

Through high-performance envelopes, efficient energy system and refined operation management and control, nearly zero-energy buildings can significantly improve the indoor thermal comfort and reduce fossil energy consumption by 60% to 75% compared with ordinary buildings. Meanwhile, with the large-scale promotion of nearly zero-energy buildings, the nearly zero-energy communities have gradually become the new form of modern large-scale urban. However, there are still many scientific challenges for energy systems of nearly zero-energy communities and buildings, such as renewable energy utilization, match between supply and demand, indoor thermal comfort improvement, etc. Therefore, nearly zero-energy communities and buildings have become a major focus for the sustainable development of society.

This Special Issue collects research articles and critical reviews about scientific and technical information on recent advances in nearly zero-energy communities and buildings for sustainable development. Both qualitative and quantitative studies, as well as empirical and theoretical contributions are welcomed.

The primary areas of interest of this Special Issue include, but are not limited to:

Low/zero carbon emission buildings and communities;
Renewable energy utilization and consumption;
Optimization design methods of energy system;
Advanced modelling and building simulations;
Indoor thermal comfort;
Energy storage technology;
Load demand responses.

I look forward to receiving your contributions.

Abstract

This work presents an improved self-adaptive power distribution approach for the microgrid in five modes under different pandemic conditions in a typical tourism water village in Northern China. Differently from the other studies, this work concentrates on satisfying the specific power supply requirements under the COVID-19 background, with the maximum value of the composite index as the object function. Composite index includes not only the economic factors, but also some compulsive factors to ensure the requested power supply of the residents/tourists. The improved particle swarm optimization method which employs the modified weighted factor and the elite strategy is utilized to optimize the power dispatching of the microgrid. Moreover, the impact of the pandemic has been fully considered by comparing the power dispatching before and after the pandemic. The case study in Baiyangdian Region confirms the effectiveness of the proposed method. With this method, the optimal power dispatching is determined under different modes. Full article

Abstract

In recent decades, the additive manufacturing technology has made great progress in software and methods in various fields, and gradually explored in a deeper and broader manner. It has changed from the mature homogenized lattice type and model design to a non-uniform direction. It has also started to improve from the aspects of material innovation, additive manufacturing printing technology, etc., to change the additive manufacturing technology and control parameters in the manufacturing process, Furthermore, the model or part can be improved to have better mechanical properties, such as stiffness, strength and wear resistance, which provides an important research methodology for the better development of this direction. These aspects include the software used, the type of structural analysis, the software used and verification, as well as the methods applied in the study of variable density lattices and the application and verification of improved research methods. In addition, there are density design optimization, variable density lattice design and lattice geometric characteristics’ design in geometric topology optimization design. The expected design of the model or part at the design level has reached the ideal model or part, which provides both a framework and ideas for the future research direction of non-uniform lattice design and a broader field of application, and will promote the future research and development prospects of variable density lattices.
