Special Issue Information

Dear Colleagues,

Sustainable energy systems have become a defining priority in contemporary building design, driven by the need to reduce emissions, improve resilience, and enhance occupant comfort while meeting ambitious energy and climate targets. This Special Issue, “Sustainable Energy Systems in Building Design: Innovations and Performance Optimization,” aims to highlight state-of-the-art research and practical advances that accelerate the transition toward high-performance, low-carbon buildings. It provides a forum for researchers, engineers, architects, and industry professionals to share findings on the integration, control, and optimization of energy systems across building scales.

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

  • High-efficiency heat pump technologies;
  • Low-GWP and natural refrigerants for heat pumps in buildings;
  • Renewable energy systems in buildings (photovoltaics, solar thermal, geothermal energy, small-scale wind turbines);
  • On-site energy generation solutions and integration with storage and smart control energy storage;
  • Smart controls, automation, and predictive operation;
  • Innovative and adaptive building envelope technologies;
  • Building energy modeling, digital twins, and data-driven optimization;
  • Demand response and grid-interactive efficient buildings;
  • Life-cycle assessment and cost-optimal design;
  • Design strategies for positive energy buildings;
  • Real-world case studies demonstrating measured performance, commissioning, and post-occupancy evaluation;
  • Performance verification through monitoring, commissioning, and post-occupancy evaluation;
  • Thermal comfort enhancement and mitigation of heat stress under extreme conditions;
  • Minimization of peak heating and cooling loads through passive measures, advanced controls, and demand-side management;
  • Phase change material for energy storage;
  • Thermochromic materials and cool roofs;
  • Hydrogen storage in the building environment.

Restaurants are a category of commercial buildings highly sensitive to dynamic changes in ambient parameters, such as thermal, internal air quality, luminous, and acoustic conditions. These fluctuations in environmental comfort yield distinct energy, ecological, and economic implications, posing a significant challenge to understanding building behavior, particularly during the cooling season. The subject of this case study is a restaurant building featuring an atrium space located in Kragujevac (Central Serbia). Its unique architectural form, which aligns with national energy efficiency principles, combined with favorable local parameters characteristic of a moderate continental climate, enables the implementation of bioclimatic measures for the passive reduction of final energy consumption during the cooling season. Therefore, using Google SketchUp 8 and EnergyPlus 7.1 software, eight bioclimatic measures, classified into three groups, were investigated: horizontal overhangs, horizontal pergolas, and deciduous plants. The numerical simulations show that using V. coignetiae as a roof covering for restaurant buildings is optimal across all the criteria. It achieves a one-season payback period, with seasonal specific metrics of 58.2 kWh/(m2season) for total final energy consumption, 145.5 kWh/(m2season) for total primary energy consumption, and 77.11 kg/(m2season) for total CO2 emissions. In addition, a moderate continental climate suits green architecture and passive solar systems. This study confirms that the bioclimatic measures achieve energy, ecological, and economic justification solely through an integrated approach and a detailed analysis. Integrating these measures during architectural design maximizes their positive effects, ensuring optimal building performance throughout its entire operational life. Full article
