“…If the island is far away from the mainland, the construction cost is serious. Without damaging the environment, using coral to replace part of the coarse aggregate can effectively reduce the cost and shorten the construction time [21]. Therefore, it is feasible to use coral as an aggregate for mixing concrete.…”

Multiphase lightweight aggregate concrete (MLAC) is a green composite building material prepared by replacing part of the crushed stone in concrete with other coarse aggregates to save construction ore resources. For the best MLAC performance in this paper, four kinds of coarse aggregate—coal gangue ceramsite, fly ash ceramsite, pumice and coral—were used in different dosages (10%, 20%, 30% and 40%) of the total coarse aggregate replacement. Mechanical property and impact resistance tests on each MLAC group showed that, when coal gangue ceramsite was 20%, the mechanical properties and impact resistance of concrete were the best. The compressive, flexural and splitting tensile strength and impact energy dissipation increased by 29.25, 19.93, 13.89 and 8.2%, respectively, compared with benchmark concrete. The impact loss evolution equation established by the two-parameter Weibull distribution model effectively describes the damage evolution process of MLAC under dynamic loading. The results of a comprehensive performance evaluation of four multiphase light aggregate concretes are coal gangue ceramsite concrete (CGC) > fly ash ceramsite concrete (FAC) > coral aggregate concrete (CC) > pumice aggregate concrete (PC).

“…Research on the formation mechanism of indoor hygrothermal environment is of very important engineering application value for better realize zero energy consumption of building envelope and optimize indoor environment [13]. Johra et al [14] constructed an indoor hygrothermal environment model which is composed of an indoor hygrothermal balance equation and a coupled faç ade hygrothermal transfer model, they tested the change law of indoor hygrothermal environment under different weather conditions and applied actual cases to analyze the impact of different building envelop structures on the cooling load of air conditioners, the heating load of heaters, and the indoor hygrothermal environment; then they proposed a set of indoor hygrothermal environment regulation methods that suit the load characteristics of zero energy consumption buildings. The coupled hygrothermal transfer of external facade materials have a great impact on the energy consumption of air conditioners and the indoor hygrothermal environment [15][16][17][18].…”

For tourism industry, the ever-increasing energy consumption and the high carbon emissions are requiring close attention and prompt solution, thusly endowing the research on the energy-saving of buildings in tourist resorts very important and practical significance. For this reason, this study carefully considered the actual situations such the energy utilization method and the hygrothermal environment of tourist resorts and constructed a hygrothermal transfer model and the corresponding hygrothermal balance equation for buildings in tourist resorts; then, the paper proposed a few effective strategies for the energy-saving management of buildings in tourist resorts, and studied the annual energy consumption of tourist resorts and gave a building energy consumption analysis. At last, experimental results verified the rationality and effectiveness of the proposed energy consumption assessment and energy-saving management methods for tourist resort buildings in hygrothermal environment. This study provided a useful reference for the energy-saving methods of buildings in tourist resorts.
