Special Issue Information

Dear Colleagues,

We currently live in a global context where climate change has paved the way for new initiatives to reduce carbon emissions. In light of this situation, the focus on GHG emissions management, the environmental impact of the built environment, and the optimization of environmental performance have become essential. Since most energy losses are due to air renovations and infiltrations, building ventilation has become a difficult challenge to improve energy management, as it is also closely related to human health and well-being. For this reason, it is vital that possible implementation techniques take into account the balance between indoor air quality and energy efficiency in the air renovations of buildings. Focusing on this will allow us to have a deeper understanding of buildings’ ventilation, as well as the quality of the air introduced. Original works that also deal with methodologies, numerical and experimental research, and case studies with a particular focus on the comfort conditions of the occupants and the influence of occupant habits in sustainable buildings and the effects of climate change on the built environment are welcome. Topics of interest include but are not exclusive to:

  • Efficient ventilation strategies;
  • Habits and comfort of the occupants;
  • Energy efficient buildings;
  • Building codes and standards;
  • Sustainable building materials;
  • Passive and active strategies;
  • Energy-saving strategies;
  • Air quality monitoring;
  • Air pollution control;
  • Housing and health;
  • HVAC control systems.

The need to reduce energy consumption in buildings is an urgent task. Increasing the use of calibrated building energy models (BEM) could accelerate this need. The calibration process of these models is a highly under-determined problem that normally yields multiple solutions. Among the uncertainties of calibration, the weather file has a primary position. The objective of this paper is to provide a methodology for selecting the optimal weather file when an on-site weather station with local sensors is available and what is the alternative option when it is not and a mathematically evaluation has to be done with sensors from nearby stations (third-party providers). We provide a quality assessment of models based on the Coefficient of Variation of the Root Mean Square Error (CV(RMSE)) and the Square Pearson Correlation Coefficient (R2). The research was developed on a control experiment conducted by Annex 58 and a previous calibration study. This is based on the results obtained with the study case based on the data provided by their N2 house. Full article

Real-time estimation of three-dimensional field data for enclosed spaces is critical to HVAC control. This task is challenging, especially for large enclosed spaces with complex geometry, due to the nonuniform distribution and nonlinear variations of many environmental variables. Moreover, constructing and maintaining a network of sensors to fully cover the entire space is very costly, and insufficient sensor data might deteriorate system performance. Facing such a dilemma, gappy proper orthogonal decomposition (POD) offers a solution to provide three-dimensional field data with a limited number of sensor measurements. In this study, a gappy POD method for real-time reconstruction of contaminant distribution in an enclosed space is proposed by combining the POD method with a limited number of sensor measurements. To evaluate the gappy POD method, a computational fluid dynamics (CFD) model is utilized to perform a numerical simulation to validate the effectiveness of the gappy POD method in reconstructing contaminant distributions. In addition, the optimal sensor placement is given based on a quantitative metric to maximize the reconstruction accuracy, and the sensor placement constraints are also considered during the sensor design process. The gappy POD method is found to yield accurate reconstruction results. Further works will include the implementation of real-time control based on the POD method. Full article

The importance and urgency of energy efficiency in sustainable development are increasing. Accurate assessment of energy efficiency is of considerable significance and necessity. The data envelopment analysis (DEA) method has been widely used to study energy efficiency as a total factor efficiency assessment method. In order to summarize the latest research on DEA in the field of energy efficiency, this article first analyzes the overall situation of related literature published in 2011–2019. Subsequently, the definition, measurement and evaluation variables of energy efficiency are introduced. After that, this article reviews the current DEA model and its extension models and applications based on different scenarios. Finally, considering the shortcomings of the existing DEA model, possible future research topics are proposed. Full article
