Special Issue Information

Dear Colleagues,

More than 1/3 of the total energy of IEA countries are consumed in buildings. The last shortage in energy supply and the increasing energy prices in the last few years are increasing the importance of  green buildings. Besides the efficient energy consumption, Green buildings also define the utilization of the materials from start of the structure to abandon buildings and recycling of the used materials. Until today very good achievements were already made in Green Buildings and many new technologies are emerging in the last few years. In this Special Issue “Energy Optimization: Advanced Technologies Applied in Green Buildings”, applied advanced technologies in Green Buildings aim to be presented and introduced to researchers, scientists, engineers, architects and other people who interested in these topics.

Research studies, applied for theoretical or experimental works and review papers are expected for this special issue. Relevant topics, including but not limited to:

  • Energy efficiency in buildings
  • New heating & cooling and air conditioning technologies
  • Ground / water / air heat pump systems
  • Passive houses
  • Energy storage in buildings
  • Smart houses, smart systems
  • Artificial Intelligence in house management
  • Efficient lightning and electricity consumption
  • Green renovation in old buildings
  • Decreasing pollution, emissions, waste and other side effects of buildings
  • Building modeling, BIM Modeling

The measurement and analysis of the spatial attributes of the street canyon hold significant importance in the advancement of photovoltaic integrated shading devices (PVSDs). This study offers the space aspect ratio index AR(h) as a more efficient method for determining the optimal location for installing PVSDs on building facades in various street canyons. The AR(h) index addresses the limitations of the current quantitative index. This study examined the evolving regulations of indoor thermal conditions, natural lighting, and the performance of PVSDs in various street canyons. It assessed the viability of implementing PVSDs in different canyons and suggested development plans based on the variation law. The findings demonstrated that AR(h) is capable of effectively assessing and directing the implementation of PVSDs. When AR(h) is below 0.6, the shade of surrounding buildings has the least impact on the photovoltaic power output and building energy consumption in various street canyons. In this scenario, the building has the largest yearly energy-saving rate, making it highly ideal for implementing PVSDs on the building façade. In summary, the suitability of the AR(h) index in various street sceneries was assessed, offering valuable insights for the widespread implementation of PVSDs and street planning, thereby optimizing the utilization of solar energy. The findings of this study will be advantageous in diminishing the utilization of non-renewable energy sources in urban areas and mitigating carbon emissions to safeguard the environment.

Energy consumption is an essential and vital issue for commercial hotel buildings. Regulations and codes are commonly used to regulate the energy usage of the building. However, the energy index used to evaluate energy performance does not include the usage of hotel buildings for different service purposes. This study utilizes a comprehensive approach involving data collection, field measurement, regression analysis, and building energy modeling to investigate the energy performance in hotel buildings. The study finds that ambient temperature and occupancy rate are key factors in energy consumption, resulting in a weighted energy index for public areas and guest rooms with an R-square of 0.8314 and 0.9184, respectively. The measurement data are also used to perform the energy modeling, and the data are validated. Studies on different regions, occupancy, orientation, window-to-wall ratios, and U-values are evaluated and simulated to determine the energy consumption, which might be useful for the hotel building design phase. In addition, it also evaluates the energy-saving potential, including chilled and condenser water temperature, COP, and indoor temperature settings. The study finds that implementing various studies could result in significant energy consumption and savings, with higher chilled water and lower condenser water temperature having a particularly prominent impact. The study concludes that energy modeling approaches can be useful tools for identifying and implementing energy-saving strategies. Full article
