Special Issue Information

Dear Colleagues,

The building sector accounts for approximately 40% of total carbon emissions, making it a crucial aspect to consider in the pursuit of carbon neutrality. Developing sustainable buildings is thus essential in achieving this goal. The integration of solar thermal and solar electric (photovoltaic) energy systems in the building sector offers significant benefits, including heating, cooling, and substantial electricity savings, alongside the promotion of environmental sustainability.

In order to maximize the utilization of solar energy in buildings, the seasonal imbalance between supply and demand must be overcome. Seasonal thermal energy storage emerges as a pivotal technology in addressing this challenge, enhancing the efficiency of solar heating systems and thus facilitating the large-scale deployment of solar energy.

This Special Issue aims to provide an overview of the latest research and developments in solar energy. The scope of this Special Issue includes solar heating, solar cooling, PV, PVT, thermal energy storage, BIPV and more.

The compound energy system is an important component of zero-carbon buildings. Due to the complex form of the system and the difficult-to-capture characteristics of thermo-electric coupling interactions, the operation control of the zero-carbon building’s energy system is difficult in practical engineering. Therefore, it is necessary to carry out relevant optimization methods. This paper investigated the current research status of the control and scheduling of compound energy systems in zero-carbon buildings at home and abroad, selected a typical zero-carbon building as the research object, analyzed its energy system’s operational data, and proposed an operation scheduling algorithm based on day-ahead flexible programming and intraday rolling optimization. The multi-energy flow control algorithm model was developed to optimize the operation strategy of heat pump, photovoltaic, and energy storage systems. Then, the paper applied the algorithm model to a typical zero-carbon building project, and verified the actual effect of the method through the actual operational data. After applying the method in this paper, the self-absorption rate of photovoltaic power generation in the building increased by 7.13%. The research results provide a theoretical model and data support for the operation control of the zero-carbon building’s compound energy system, and could promote the market application of the compound energy system.

The energy efficiency of data centers has become an urgent problem as it is enjoying rapid development. This study proposes an integrated energy system involving a data center with different renewable energy sources and waste heat recovery, which can consider the partial and unsteady working load of data center. A dynamic and sophisticated system simulation model is established, which can provide both reliable and fast evaluations but also allow flexible extension of additional components. It is found that the free natural resource cooling system can cover about 28% of cooling demand. Compared to the reference condition, the proposed energy system achieves significant energy-saving benefits, with an energy-saving rate of 16.4%. The system COP increases from 3.88 to 4.64, and the PUE decreases from 1.36 to 1.30, resulting in a 23.45% reduction in electricity expenses. By integrating a waste heat recovery system, the heat pump can absorb approximately 3.57 million kWh of heat from the data center, providing approximately 4.587 million kWh of heating energy for users. The rooftop PV system generates approximately 370,000 kWh of electricity annually, covering approximately 8% of the total electricity consumption of the data center. This study can offer a new channel for the energy efficiency enhancement of data centers. Full article
