Special Issue Information

Dear Colleagues, 

During the last decade, climate change implications have been evermore impactful to the daily life of the population. The frequency and severity of extreme events, such as floods and heat waves, has reached incredible levels. For example, the mean earth peak temperature in 2023 has broken all records. At the same time, today’s urbanization means that people living in cities account for 56% of the population, while future predictions estimate urbanization reaching 68% by the year 2050. This poses a great need to take action and ensure more sustainable cities in the future. Tackling the building sector is indeed of high priority in the context of climate change mitigation and adaptation strategies. On the one hand, buildings are responsible for about a third of global energy consumption, which means that improved energy efficiency is necessary to reduce energy-induced carbon and GHG emissions, while on the other hand, the urban environment should be resilient to the inevitable impacts of climate change. In parallel, the vast existing building stock implies enormous investments in implementing massive energy renovation projects, especially within the urban fabric; hence, low-cost solutions for the improvement of building energy and environmental performance are of paramount importance. To confront the recognized challenges, innovative and usable tools and methods, taking into account the most important decision-making parameters, are absolutely necessary, even at the study and design stage, for better planning and controlling of building energy efficiency in cities.

This Special Issue aims to present novel advances and insights in the thematics of cost-optimal energy efficiency planning and energy management of building stocks in urban environments, in view of climate change effects in cities.

Topics of interest for publication include, but are not limited to:

  • Urban energy planning;
  • Computational and experimental methods for planning energy efficiency in the built environment;
  • Multi-criteria decision making in planning strategies for improving the energy efficiency of groups of buildings;
  • Participative approaches for involving stakeholders in energy-efficiency planning and management activities;
  • Indoor–outdoor physical models for practicing holistic energy and environmental planning for renovation at the district or city scale;
  • Formulation of adequate baseline conditions for building energy efficiency assessments, taking into account future predictions of climatic conditions;
  • Future-proofed building energy efficiency solutions;
  • Model predictive control for building energy efficiency;
  • Multi-objective optimization for balancing the most important variables, such as energy, comfort, and air quality, in buildings or groups of buildings;
  • Perspectives of exploiting soft and low-cost measures with high impacts, including end-users’ behavioral shift management, sensor-free BEMs, AI techniques, BIM and digital twinning, etc.

Urban form is an important factor affecting urban energy. However, the design of urban form and energy mostly belong to two separate disciplines and fields, and urban energy planning research rarely considers their mutual relationship. The available space intensity (ASI) of solar energy is formed on the basis of energy planning and urban design; the objective of this research is to evaluate the impact of urban form on the ASI of solar energy and to propose strategies for planning of the space that is available for solar energy so as to improve the efficiency of urban energy utilization and achieve sustainable urban development. Methodologically, this study firstly proposes a model to quantify the ASI of solar energy using three indicators: solar radiation intensity (SRI), solar installation intensity (SII), and solar generation intensity (SEGI). Then, we quantitatively calculate the solar ASI of nine types of typical urban blocks in a sub-center of Wuhan City, Nanhu. Correlation analysis and multiple linear regression analysis are then used to analyze the correlation between the form indicators and solar ASI, as well as the degree of influence. The results show that the differences in SRI, SII, and SEGI amongst the nine types of city blocks were as high as 114.61%, 162.50%, and 61.01%. The solar ASI was mainly affected by three form indicators: the building coverage ratio, the average building height, and the volume-to-area ratio. Reducing the building coverage ratio and increasing vertical development at the same time can effectively improve the ASI of solar energy. The results of this study and the established method provide an important reference and rapid calculation tool for urban energy planning and design, reducing the data and time usually required for solar analysis at the block scale.

According to the latest energy efficiency European directive (EED 2023/1791/EU), the expected energy renovation rate of at least 3% of the buildings’ floor area each year towards nearly zero-energy buildings (nZEBs) is extended to include public buildings not only of the central government (as per the first EED 2012/27/EU) but also of regional and local authorities. This poses a great challenge, especially for Municipalities that often manage large building stocks with high energy demands. In response to this challenge, this paper presents the application of the so-called “typology approach” for conducting public buildings’ energy renovation plans at the local level. A computational survey is initially introduced to decide the optimal set of building-stock clustering criteria among all possible combinations, involving the minimization of the RMSE index regarding the primary energy consumption of each building. For a representative building from each identified typology, the key performance indicators (KPIs) are computed for alternative energy-upgrading scenarios. Exploiting the IMPULSE Interreg-MED project tools, the KPIs from each representative building are at first extrapolated to all buildings of the examined stock and, finally, a gradual energy renovation plan is automatically produced based on user-defined decision parameters including the required annual renovation rate. The methodology is applied for the case of the Municipality of Hersonissos in Greece. For the specific 44-buildings’ stock it was found that the optimal clustering set included four criteria, building use, construction year, heating, and a cooling system, leading to 15 building typologies. Finally, assuming a 7% renovation rate per year, a 12-year gradual renovation (nZEB transformation) plan is obtained foreseeing an 85% CO2 emissions’ reduction. Full article
