Owing to the continuously growing energy demands in buildings, the renewable energy applied in buildings, and related research, have attracted more and more public attention. Currently, buildings consume one third of the total energy supply in developed countries and one quarter in developing countries. Both reducing building energy demands and effectively utilizing renewable energy in buildings are considered to be principal routes towards low energy and sustainable buildings. Due to the instability of the renewable energy supply, thermal energy storage technologies are also crucial to the widespread application of renewable energy in buildings.
As one of the most important renewable energy, solar energy technologies have been investigated for many years. Solar thermal (ST) technology, solar photovoltaic (PV) technology and Photovoltaic/thermal (PV/T) technology are regarded as the most feasible renewable solutions for building applications. ST technology, which is the most mature technology among all currently available solar energy technologies, has a much higher solar conversion efficiency and shorter payback time. Although, currently, PV installations in buildings are still small-scale, PV technology has already developed into a mature technology, both technically and commercially. With continuously technical advances, reduced costs and legal policies in renewable energies, the applications of PV technology will continue to grow quickly and will eventually become an important electrical energy supplier in the world. PV/T technology, which can simultaneously generate electricity and heat, takes advantages of both PV and solar thermal technologies. Due to its higher overall solar conversion efficiency and more effective use of space, the market potential of PV/T technology is expected to be higher than individual PV and solar thermal technologies.
Ground coupled heat pump (GCHP) technology has been increasingly attracting attentions as a renewable energy technology of high energy efficiency and its environmentally-friendly mechanism for space cooling and heating. The most important component of the GCHP system is the ground heat exchangers (GHEs). Compared to other types of GHEs, vertical GHEs have more benefits, such as the smaller space taken for installation and superior energy efficiency. Heat transfer analysis of vertical GHEs has always been a key issue in designing GCHP systems. In addition, another key issue for GCHP systems is that the heat rejected into the ground is usually not equal to that absorbed from the ground, which will cause heat accumulation or heat attenuation in the ground. One of the cost-effective solutions is to promote GSHP systems in so-called hybrid GSHP systems. The design and applications of hybrid GSHP systems have become a special interest in the research of GCHP technologies.
Thermal energy storage (TES) technologies, including seasonal and short-term storage technologies, are considered to be important means to solve the problems of instability in renewable energy supply and the mismatching between building energy demands and a renewable energy supply. Phase change materials (PCMs), which are widely used in various thermal energy storage systems, are particularly attractive materials due to their high energy storage densities and stable phase change temperatures. However, research work is required to improve the thermal properties of PCMs, such as low thermal conductivity and high super-cooling degree, to increase the overall heat transfer efficiency. Furthermore, investigation of new PCM materials is very important for the development of effective latent thermal storage. Additionally, good design and control strategies for PCM units are crucially important for promoting the applications of PCMs in thermal storage energy systems.
We invite researchers to contribute original research articles, as well as review articles. Your contributions will promote public understanding of the operational principles of various building-applicable renewable energy technologies and thermal energy storage systems. We are particularly interested in articles presenting novel materials, new method and theories, or innovative aspects in practical applications that can help to enhance the efficiency and reduce the costs of building renewable energy and latent heat thermal storage systems. Potential topics include, but are not limited to:
- Solar thermal systems: Domestic hot water, space heating and cooling
- Photovoltaic and building integrated photovoltaic (BIPV) technologies
- Photovoltaic/Thermal technologies
- Heat transfer of GHEs
- Design and operation strategy of hybrid GSHP
- Heat transfer in PCMs and enhancement techniques
- Characterization and development of new PCMs
- Thermal energy storage systems in buildings
- Thermal management system using PCMs
- Integration methods and application of building renewable energy and heat storage system in buildings
