Special Issue Information

Dear Colleagues,

Climate change has drastically influenced energy consumption in the building sector. In recent years, special attention has been given to improving building materials such as insulation, phase change, and cool roof materials, and integrating renewable energy systems such as solar, wind, and geothermal for the generation of electricity in building envelopes. The application of PV solar panels and transparent PV windows in building envelopes has grown, while the application of nanofluids and hybrid nanofluids has found impetus in increasing the efficiency of solar systems, e.g., solar collectors. Depending on the geometry, architecture, and local climate of a building, some of these techniques may be effective and inexpensive. However, the application of some of these techniques in buildings may raise some social and environmental issues such as auditory and visual effects for the use of wind turbines, fire safety regulations for the use of flammable insulation or bio-phase change materials, and so on. Other technical aspects such as applicability to life-cycle economy, construction costs, the feasibility of application on existing buildings, speed of installation, government regulation and building codes, and government incentives on energy products are of major concern. 

In some climates, cooling demands are substantial, while in other environments heating demands are very important. Global warming and rapid melting of Earth’s pole ices, increased CO2 footprints, and urgent demands to utilize and capture CO2 in the environment have opened up a new era for the capture and utilization of CO2 within building envelopes. To increase building efficiency, it is necessary to consider the structural, architectural, visual, economic, social, and environmental factors and address the existing and current obstacles, as well as challenges locally and globally. The application of well-designed experiments and highly reliable software packages is essential to improve energy planning and decision making in the building sector.  Therefore, the purpose of this Special Issue, entitled "Advances in Thermal Performance and Energy Efficiency of Buildings in Various Regions", is to expand the study of the development and use of passive and active energy saving systems, with a focus on application of renewable energy sources, and address the pertinent economic, social, and environmental challenges. This Special Issue will publish new contributions in construction related to architectural, engineering, environmental sciences, social and economic analysis, and the impact of energy policies. Its main readership will include researchers and planners at universities, research institutes, industry, government departments, building developers, and policymakers in developing and exploiting buildings’ energy efficiency.

We welcome this Special Issue the submission of original research articles and reviews. Research areas may include (but are not limited to) the following:

  • New materials in residential/office/industrial buildings’ envelope.
  • New application of renewable energies in buildings’ architecture.
  • Application and capture of CO2 within buildings’ envelope.
  • Application of low-energy lighting and ventilation systems.
  • Advances in insulation materials and methods in buildings.
  • Advances in application of smart passive materials, e.g., phase change materials, in building envelope.
  • Advances in application of smart materials, e.g., hybrid nanofluids, PV windows, in buildings’ energy systems.
  • Identifying social, economic, and environmental barriers related to governmental regulations and building developers in building sector.
  • Identifying technological barrier on developing zero-energy buildings.
  • Feasibility studies to enhance energy efficiency of existing buildings.
  • Planning and imposing new regulations and policies in executing essentials in new and under developing buildings.
  • Examining impacts of Corona epidemy in social behavior on energy consumption in buildings.
  • Strategies for energy efficiency in developing and under developing countries and examining social, economic, and environmental issues.

We look forward to receiving your contributions.

The global population’s growth and increased energy consumption have driven greenhouse gas (GHG) emissions. In Canada, the residential sector accounts for 17% of secondary energy use and 13% of GHG emissions. To mitigate GHG emissions, promoting renewable energy and efficient heating systems is crucial, especially in cold climates like Canada, where there is a heavy dependency on fossil fuels for space heating applications. A viable solution is hybrid fuel heating systems that combine electric-driven air-source heat pumps (ASHPs) with natural gas tankless water heaters (TWHs). This system can alternate its operation between the ASHP and TWH based on efficiency and real-time energy costs, reducing grid peak demand and enhancing resilience during power outages. Although lab experiments have shown its benefits, in situ performance lacks evaluation. This study analyzes the in situ energy performance of a net-zero ready house and its hybrid fuel heating system, assessing energy consumption, hourly space heating output, and system heating performance. HOT2000 is a robust simulation software designed for assessing energy consumption, space heating, cooling, and domestic hot water systems in residential buildings. An artificial neural network model was developed to predict the energy performance of the hybrid fuel system, which was used as a substitute for monitored data for evaluating the HOT2000’s simulation results under the same weather conditions. Therefore, this study proposes a comprehensive framework for the in situ performance analysis of hybrid fuel heating systems. This study then, using HOT2000 energy consumption results, evaluates the life cycle costs of the hybrid fuel system against conventional heating systems. Furthermore, this study proposes an economical control strategy using in situ data or manufacturer specifications. Full article

The building sector’s energy consumption has significantly increased due to climate change, emphasizing the need to develop sustainable low-energy buildings using experimental and computational tools. As a joint project between Kuwait and Australia, two portable cabins with internal sizes of 2 m × 2 m × 2.80 m, made from 75 mm thick sandwich panels and metal frames, were built in Kuwait to investigate their thermal and power consumption characteristics under various energy-saving techniques and different climates. This is the first attempt to analyze the energy-saving aspects of portable cabins made from sandwich panels for future sustainable cities. Each cabin has an indoor air-quality-sensing device and a novel power-monitoring system to measure their thermal and power consumption characteristics. First, shingles and novel finned metal cool roof (CR) techniques were experimentally investigated. Then, a new multi-zone SketchUp model of the portable cabins was created and simulated in TRNSYS. Next, the energy saving data of the portable cabins were investigated by adding PCM on the walls and the roof using built-in models of bio-phase change materials (Bio-PCMs) in TRNSYS. The annual energy performance index (EPI) as an important sustainability index was explored for determining heating/cooling/total demands of the portable cabins in the desert climate of Kuwait and in various climate regions of Australia. The findings reveal that both shingles and finned metal roofs contributed to higher power consumption. Meanwhile, the use of sustainable Bio-PCMs in Kuwait demonstrates a significant energy-saving potential of 30%, with variations ranging from 25% to over 45% across different climate regions in Australia.
