Special Issue Information

Dear Colleagues,

At present, energy utilization and carbon emissions have become important issues on a global scale and have received great attention from the international community. In order to cope with the dual pressures of climate change and the energy crisis, many countries have formulated a series of energy-saving and carbon-reduction policies to limit the consumption of fossil energy in various industries. According to the United Nations Environment Programme's newly released "2022 Global Status Report for Buildings and Construction", the construction industry accounts for up to 34% and 35% of global total energy consumption and carbon emissions, respectively. In particular, the International Energy Agency's CO2 Emissions in 2022 states that global energy-related CO2 emissions increased by 321 Mt in 2022, of which 60 Mt CO2 can be attributed to cooling and heating demand in extreme weather.

Therefore, how to reduce the energy consumption and carbon emissions of buildings while pursuing higher thermal comfort has become the focus of scholars in the architecture field. Improving the heat transfer performance of buildings, reducing the energy demand for heating and cooling in buildings, and increasing the proportion of renewable energy are effective ways to save energy and reduce carbon in buildings.

Despite the existence of many studies dedicated to exploring energy utilization and carbon emissions, there are still many challenges and opportunities for energy saving and emission reduction in building heating and cooling. In this regard, the journal Buildings announces a call for papers for a Special Issue devoted to "Heat Pump Systems and Thermal Technology for Buildings". The Special Issue seeks papers that expand upon the current literature and understanding of the buildings thermal technology and heat pump systems. Papers discussing how to use advanced building technology and envelope high-performance buildings are also welcome. Original research and review papers on the following topics are welcome:

  • Energy efficiency in buildings;
  • Building heat pump (ground source, air source, etc.) systems;
  • Building renewable energy air conditioning system;
  • Building thermal environment control;
  • Building intelligent ventilation;
  • Building intelligent energy system;
  • Electricity demand response technologies for building air conditioning systems;
  • Building renewable energy utilization technology;
  • Passive building energy-saving technology;
  • New building envelope structures;
  • Utilization of high-performance building envelope materials;
  • Building heat transfer model;
  • Thermal performance of building components (walls, floors, roofs, windows, doors, etc.);
  • Building active and passive thermal storage technologies.

All types of research methods are acceptable: experimental, theoretical, numerical, analytical, computational, case studies, etc. The main criteria accepted by the paper are academic excellence, scientific rationality, and originality and novelty of applications, methods or experiments.

This study aims to investigate and identify the most effective thermal energy storage (TES) system configuration for the collective heating of buildings. It compares three TES technologies, i.e., sensible, latent, and cascade latent shell and tube storage, and examines their respective performances. A fast and accurate lumped thermal dynamic model to efficiently simulate TES system performances under different operation conditions is developed. The validation of this model’s accuracy is achieved by aligning numerical findings with data from prior experimental studies. Key findings indicated that the latent and cascade latent shell and tube storage systems demonstrate superior thermal energy storage capacities compared to the sensible configuration. Using a single-phase change material (PCM) tank increases the duration of constant thermal power storage by about 50%, and using a cascade PCM tank further enhances this duration by approximately 65% compared to the sensible TES case. Moreover, the study revealed that adjusting the PCM composition within the cascade TES significantly influenced both thermal power storage durations and pumping energy consumption. In summary, the recommended cascade PCM configuration for collective heating of buildings offers a balanced solution, ensuring prolonged stable thermal power production, elevated HTF outlet temperatures, and improved energy efficiency, presenting promising prospects for enhancing TES systems in district heating applications.
