Special Issue Information

Dear Colleagues,

This Special Issue on "Advanced Technologies for Energy-Efficient Buildings—2nd Edition" focuses on innovative approaches and technologies that improve the energy efficiency of buildings. It explores solutions for reducing energy consumption and minimizing environmental impacts in both residential and commercial structures. It incorporates a wide range of innovative topics that address both technical and socio-spatial aspects of energy efficiency in the built environment. The Issue brings together research and case studies that contribute to the development of greener, more sustainable building practices.

Topics include, but are not limited to, the following:

  • Smart building systems: Integration of intelligent controls and automation for optimizing energy use.
  • Energy-efficient materials: Use of sustainable, high-performance materials in construction and insulation.
  • Renewable energy integration: Systems like solar panels, wind energy, and heat pumps that can be incorporated into building designs.
  • Energy management systems: Software and hardware solutions to monitor and control energy consumption.
  • Retrofitting strategies: Upgrading existing buildings with modern technologies to improve energy efficiency.
  • Adaptive reappropriation: Techniques for repurposing existing structures, such as retrofitting old buildings to improve energy performance and sustainability, while preserving their architectural integrity.
  • Educational buildings: Case studies and research on the application of energy-efficient technologies in schools and universities, creating more sustainable learning environments.
  • Spatial analysis and evidence-based approaches: The use of advanced spatial analytics to understand how building design impacts energy use. Evidence-based approaches ensure that design decisions are supported by data, optimizing energy consumption in different spaces.
  • Socio-spatial sustainability: Investigating the relationship between social factors, space utilization, and sustainability, focusing on how energy-efficient buildings can enhance social well-being and community cohesion.

Abstract
PV/T collectors and Air Source Heat Pump (ASHP) are widely studied for building heating, but solar intermittency and ASHP low-temperature frosting limit their large-scale deployment. A novel PV/T-ASHP coupled heating system is proposed to cut building carbon emissions and relieve ASHP performance degradation [...] Read more.
PV/T collectors and Air Source Heat Pump (ASHP) are widely studied for building heating, but solar intermittency and ASHP low-temperature frosting limit their large-scale deployment. A novel PV/T-ASHP coupled heating system is proposed to cut building carbon emissions and relieve ASHP performance degradation in cold zones. Circulating water cools PV/T panels to boost power generation, and the warmed water preheats ASHP evaporator inlet air to reduce frosting and defrosting frequency. With a Xi’an office building as the research object, validated TRNSYS 18.0 models are established for comparative analysis with conventional systems and cross-climate evaluation in Xi’an, Beijing, Shanghai and Chengdu. Results show the new system lifts PV/T combined efficiency by 17.56%, reduces energy consumption by 19.9%, and achieves an average COP of 3.2. Across climate zones, its COP rises 11.5–24.6% and 50-year carbon emissions fall 16.4–26.2%, supporting low-carbon heating promotion for office buildings. Full article

This study assessed the perceived effectiveness of sustainable building technologies and design strategies in improving building energy efficiency within the South African construction industry. Adopting a quantitative research approach, data were collected from 118 construction professionals in the Free State Province, South Africa, using a structured survey questionnaire administered through purposive sampling. Data analysis was conducted using SPSS, employing descriptive statistics, reliability analysis, correlation analysis, and Principal Component Analysis (PCA). The findings indicate that all investigated technologies and design strategies positively contribute to building energy efficiency and are significantly interrelated. The strong correlations among these technologies, supported by PCA results explaining 76.85% of the total variance through two principal components, suggest that sustainable building technologies are most effective when implemented as an integrated system rather than as isolated interventions. This implies that integrating energy-efficient technologies such as passive design strategies, renewable energy systems, green infrastructure, and intelligent building management systems can yield greater energy performance benefits than deploying individual technologies independently. These findings offer practical guidance for construction professionals and policymakers aiming to promote energy-efficient buildings. While limited to the Free State Province, the study provides valuable empirical evidence on sustainable building technologies within the South African context. Full article
