Multi-criteria decision-making (MCDM) can introduce the best option based on evidence. We integrated the Analytic Hierarchy Process (AHP) and the Technique for Order of Preference by Similarity to the Ideal Solution (TOPSIS) to prioritize the alternatives for photocatalytic diazinon removal in a bench scale and characterized TiO2-MIL-53(Fe) for this purpose. Criteria and alternatives were listed based on systematic literature reviews and expert opinions. Then, AHP and TOPSIS questionnaires were developed and distributed to an expert panel for pairwise comparisons. We converted the linguistic variables into the corresponding fuzzy values and used R for mathematical calculations. Then, TiO2-MIL-53(Fe) was synthesized and characterized for diazinon removal under LED visible light. The AHP ranked criteria as availability > degradation efficiency > safety for the environment > material cost > energy consumption > mineralization efficiency > photocatalyst reusability > safety for personnel > equipment cost. Based on TOPSIS, the order of alternatives was TiO2-containing/Visible light > ZnO-containing/UV light > TiO2-containing/UV light > ZnO-containing/Visible light > WO3-containing/UV light. With a bandgap of 1.8 eV, TiO2-MIL-53(Fe) could remove 89.35% of diazinon at 10 mg/L diazinon concentration, 750 mg/L catalyst dose, pH 6.8, and 180-min reaction time. Hybrid AHP-TOPSIS identified the best option for photocatalytic diazinon removal from aqueous solutions. Thus, MCDM techniques can use systematic review results to overcome the uncertainty in designing experimental studies.

“…Weights can be established in various ways, with different limitations depending on which data type is used to evaluate the potential consequences for occupants [12]. Some relative weight models prioritize health risks by using statistics associating exposure to a given condition; others prioritize perceived IE by relying on subjective occupant evaluations, while others still combine both approaches by asking topic experts for insight into both of the former [13]. Since there is no consensus in the literature and weights are very context-specific, we present the methodology without fixed weights but with the principle of relative weights integrated into the assessment architecture.…”

Indoor environmental quality (IEQ) measurement is a fundamental part of quantifying the performance of any space. Performing measurements and interpreting the results require expensive equipment and specialist knowledge for each parameter. Since holistic IEQ assessment requires investigation of multiple parameters across atmospheric, thermal, acoustic, and visual indoor environment, this is a comprehensive and expensive task. The IEQ Occupant Manikin concept presents an operational holistic IEQ assessment based on measurements of various parameters. The paper presents the development of a prototype manikin equipped with various sensors strategically positioned to best represent the exposure occupants would experience. Since the manikin also physically mimics an occupant in the space, the term occupant-centric measurements is used. In addition, the paper presents a preliminary methodology for the assessment, weighting, and aggregation of individual IEQ parameters towards an overall holistic IEQ assessment. Practical implementation of the work is discussed, including the potential implications for standards on IEQ measurement. The paper reflects upon the future perspectives on using machine learning for a black box modelling approach to tackle the complex issues with the interaction effects between IEQ parameters and relative IEQ parameter weights for holistic assessment. Finally, the paper presents suggestions for future work on the IEQ Occupant Manikin concept.

The term “comfort” has a number of nuances and meanings according to the specific context. This study was aimed at providing a review of the influence (or “weight”) of the different factors that contribute to global comfort, commonly known as indoor environmental quality (IEQ). A dedicated section includes the methodologies and strategies for finding the most relevant studies on this topic. Resulting in 85 studies, this review outlines 27 studies containing 26 different weightings and 9 global comfort indices (GCIs) with a formula. After an overview of the main concepts, basic definitions, indices, methods and possible strategies for each type of comfort, the studies on the IEQ categories weights to reach a global comfort index are reviewed. A particular interest was paid to research with a focus on green buildings and smart homes. The core section includes global indoor environmental quality indices, besides a specific emphasis on indices found in recent literature to understand the best aspects that they all share. For each of these overall indices, some specific details are shown, such as the comfort categories, the general formula, and the methods employed. The last section reports IEQ elements percentage weighting summary, common aspects of GCIs, requisites for an indoor global comfort index (IGCI), and models adopted in comfort category weighting. Furthermore, current trends are described in the concluding remarks pointing to a better IGCI by considering additional aspects and eventually adopting artificial intelligence algorithms. This leads to the optimal control of any actuator, maximising energy savings.
