Advances in Building Simulation

Topic Information

Dear Colleagues,

We would like to invite submissions to the Topical Collection ‘Advances in Building Simulation’. Building simulation plays a critical role in the assessment of alterative designs and optimization of building performances, including energy use, indoor air quality, occupants’ thermal comfort, and cost. Recent advances in computational tools and resources elevated building simulation to the next level, and they are increasingly narrowing the gap that exists between measurements and simulation results of a real building. These assist in the definition of more realistic outdoor boundary conditions through consideration of airflow and heat exchange around a building; mapping of two- and three-dimensional indoor air and pollutant distributions; integration and co-simulation of renewable, and dynamic envelope systems. This Topical Collection aims to collect the latest developments and advances in computational methods and applications for buildings. The target audience of this Topical Collection includes researchers, designers, academician, and practitioners who are working and interested in relevant topics. Topics of interest for publication include, but are not limited to:

• Micro-climate modeling of airflow and wind drive rain around buildings;
• Indoor airflow and pollutant distributions in buildings;
• Performance optimization of buildings;
• Application of machine learning for data-driven building performance analysis;
• Urban-Heat-Island (UHI) effect on building energy performance and pedestrian thermal comfort;
• Co-simulation of renewable and active envelope systems with buildings;
• Mechanical systems performance optimization with model predicative controls;
• Hygrothermal and thermal analysis of building envelope components;
• Carbon based building design and analysis;
• Heat recovery technology in building applications;
• Building energy performance simulation;
• Free cooling strategies for residential buildings;
• Energy conservation measures for new and existing buildings.

As a high-quality building material exhibiting excellent toughness and durability, ultrahigh-performance concrete (UHPC) is increasingly being used in the construction industry and as building reinforcement. During the reinforcement of existing concrete structures with UHPC, their interface is the weakest part of a structure. Interface bonding ensures the operation of two types of materials together. However, existing studies rarely report the bonding of the UHPC–normal concrete (NC) interface. Herein, the existing test methods and interface bonding mechanisms are summarized. Subsequently, the differences among relevant design codes are investigated by comparing different theoretical formulas. Important influencing factors of the reinforcement method, namely, interface roughness, fiber type and content, interface agent type and content, moisture content, existing concrete strength, cementitious material content, curing conditions, freeze–thaw cycles, and chloride ions, are also considered. Further, the enhancement mechanism of the characteristics of the UHPC–NC interface is clearly described. Finally, the shortcomings and application prospects of the interfacial bonding properties are highlighted. Full article

Climate change and urban heat island effects affect the energy consumption of buildings in urban heat islands. In order to meet the requirements of engineering applications for detailed daily design parameters for air conditioning, the 15-year summer meteorological data for Beijing and Shanghai and the corresponding average heat island intensity data were analyzed. Using the CRITIC objective weighting method and K-means clustering analysis, the hourly change coefficient, β, of dry bulb temperature was calculated, and the LSTM algorithm was used to predict the changing trends in β. Finally, the air conditioning load model for a hospital was established using DeST (version DeST3.0 1.0.2107.14 20220712) software, and the air conditioning cooling load in summer was calculated and predicted. The results show that, compared with the original design days, regional differences in the new design days are more obvious, the maximum temperature and time have changed, and the design days parameters are more consistent with the local meteorological conditions. Design day temperatures in Shanghai are expected to continue rising for some time to come, while those in Beijing are expected to gradually return to previous levels. Among hospital buildings, the cooling load of outpatient buildings in Beijing and Shanghai will decrease by 0.69% and increase by 12.61% and by 12.12% and 15.51%, respectively, under the influence of the heat island effect. It is predicted to decrease by 1.35% and increase by 29.75%, respectively, in future. The cooling load of inpatient buildings in Beijing and Shanghai increased by 0.27% and 6.71%, respectively, and increased by 7.13% and 8.09%, respectively, under the influence of the heat island effect, and is predicted to decrease by 0.93% and increase by 16.07%, respectively, in future.

In the event of a typhoon, the majority of houses suffer from large amounts of damage because they were not built with typhoon resilience in mind. For instance, the Philippines is one of the world’s most vulnerable countries to typhoons. Often, roof structures are ripped off during typhoons with average or more vigorous wind gustiness, and houses are easily ruined. This situation led us to search for the appropriate building orientation and roof angle of single-family residential houses through simulations using MATLAB’s genetic algorithm (GA) and SolidWorks’ computational fluid dynamics (CFD). The GA provides the set of design points, while CFD generates a fitness score for each design point. The goal of the optimization is to determine the orientation and roof angle while minimizing the drag force along the direction of a constant wind speed (315 km/h). The lower and upper bounds for house orientation are 0${}^{\circ }$ and 90${}^{\circ }$, respectively; the roof angle is between 3${}^{\circ }$ and 60${}^{\circ }$. After 100 generations, the GA converged to values equal to an 80${}^{\circ }$ orientation and 11${}^{\circ }$ roof angle. The final results provide a good standpoint for future experiments on physical structures. Full article

Generally, ground-coupled floor heat transfer is supposed as annual periodic, which is reasonable for conventional buildings. However, for emergency housing with a short life cycle, the influence of initial soil temperature needs to be considered. In a previous study, the Wiener–Hopf technique was introduced to solve the two-dimensional transient heat transfer equation with mixed Dirichlet and Robin boundary conditions. Based on that, an analytical solution of the dynamic heat transfer equation with initial soil temperature conditions was obtained. Since the solution was in the form of a double integral, its numerical evaluation method was also analyzed to improve computational efficiency. The accuracy and efficiency of the solution were validated by the finite volume method. Then, the effects of initial soil temperatures in different seasons, soil heat conductivities, and floor insulation on ground-coupled heat transfer were discussed. Results showed significant temperature differences between the current solution and the annual periodic solutions (long-time solutions), especially in hot and cold climates. Moreover, the larger the thermal capacity of the soil, the bigger temperature differences occurred. Therefore, this study is expected to provide a theoretical foundation for the indoor environment prediction and optimization design of emergency temporary housing. Full article
