Special Issue Information

Dear Colleagues,

The Solaris conference network provides a platform for meetings for professionals researching areas of solar radiation and daylighting to meet, solar energy conversion systems and efficient energy use in the built environment. It has a long tradition of organizing such meetings (Edinburgh 2003, Athens 2005, Delhi 2007, Hong Kong 2008, Brno 2011, Granada 2013, Maribor 2015 and London 2017). The conference aims to present the state-of-the-art in the solar energy and building energy research, to establish close contact amongst researchers for dissemination of their research outcomes and facilitate professional collaboration. For better dissemination of the technologies and methods related to solar energy and built environment, high-quality papers selected from the 9th edition of the international SOLARIS conference will be published in this Special Issue. Topics include, but are not limited to:

  1. Solar radiation measurement and modelling;
  2. Daylighting modelling and measurement;
  3. Solar thermal energy conversion;
  4. Solar photovoltaic (PV) generation;
  5. Solar energy materials;
  6. Solar technologies for buildings;
  7. Energy storage;
  8. Near zero energy buildings and efficient energy use in the built environment;
  9. District heating/cooling, and
  10. Solar energy markets and political aspects of solar development.

As the quantity of direct current (DC) load and wireless power transmission (WPT) devices are continuously increasing in building, in order to efficiently utilize renewable energy (which outputs DC power) such as photovoltaic (PV), especially for building integrated photovoltaic (BIPV), and regeneration energy from elevators (which also outputs DC power), a novel building power distribution system architecture is explored in consideration of the characteristics of supply and demand-side in this paper. The proposed architecture is a hybrid framework integrated with conventional alternating current (AC) power distribution system, DC power distribution and WPT system. The applied AC and DC hybrid power distribution system has higher conversion efficiency than a single AC power system, which indicates that the former is becoming an important trend of building power distribution. In addition, the results of experimental test in a case study suggest that the proposed architecture can provide fine service for efficient application of renewable energy and regeneration energy in building. The obtained results also can serve as a foundation to promote the development of building power distribution system and related practical application in building. Full article

Research on concentrated solar power (CSP) plants has been increasing in recent years. Supercritical carbon dioxide (S-CO2) has been applied to solar power plants due to its promising physical properties. S-CO2 has a relatively low critical temperature of 31.1 °C and owns high density in the supercritical region. Hence, it is a vital working fluid in the application of low temperature heat source and miniature power equipment. Due to the fact that solar power system has a constantly changing heat source according to season and weather, a satisfactory off-design performance is necessary for the turbine in a solar power system. In this work, a S-CO2 radial-inflow turbine based on CSP is designed. A thorough numerical analysis of the turbine is then performed. To investigate the off-design performance of this turbine, three types of nozzle profiles with different leading edge diameters are adopted. Mach number, temperature and pressure distribution are covered to present the off-design effect with different nozzle profiles. Moreover, the relation of output power, mass flow rate and efficiency with different leading edge diameter (LED) are analyzed. Results show that different LED has a vital influence on the aerodynamic characteristics and off-design performance of the S-CO2 turbine based on CSP. In addition, the designed turbine with LED = 4 mm can obtain the highest mass flow rate and output power. While the turbine with LED = 10 mm provides slightly better off-design efficiency for CSP plants. Full article

With accelerating urbanization, lighting problems frequently appears for residents at lower levels of buildings. In order to solve the sunlight blocking problem between high buildings, a new solar optical guide lighting (SOGL) system is proposed in this study. Numerical simulations are carried out to evaluate the SOGL system according to the light distribution both inside the buildings and between building groups at different times. Experimental setups are built to validate the simulated results. Main factors influencing the optical efficiency are discussed. It is found from this study that the SOGL system can realize the lighting purpose inside and between high buildings. The shadow areas between buildings are lightened into acceptable levels. The stronger the solar irradiation is, the higher the optical efficiency would be. And decreasing the ratio of optical guide pipe length to its radius would lead to the rise of optical efficiency.
