COVID 19 - A Qualitative Review for the Reorganization of Human Living Environments

The COVID-19 pandemic is changing people’s habits and behaviors and will reshape city layout and management. Among the different areas of research to be explored, the paper outlines first inputs to use the COVID-19 health crisis as a “window of opportunity” to trigger a sustainable transition of urban living environments, through actions to reshape and territorial organization after COVID-19 and in preparation for future health. Before having a vaccine or medications that ensure a non-lethal disease course, there will be a phase of responsibility and coexistence with the virus. It will be a period whose duration experts are still unable to quantify. What changes in the city organization, behaviors and uses of spaces will we observe in the living environments? Will this lead to a sustainability transition? The paper proposes a qualitative review to investigate how the droplet might travel through the air and how COVID-19 has spread in different urban contexts to outline a comprehensive reflection on the future of the city and strategies for more resilient communities and territories. To achieve this goal, the paper proposes the need of a comparison between skills related to physics aspects, such as fluid dynamics (to assess how droplets spread) and skills related to architectural, urban and territorial design (to evaluate the conditions of indoor and outdoor living environments)

Environmental Quality Index In Hospital Patient’s Rooms. Rapid assessment tool for the verification and design

The research proposes an environmental quality system assessment in hospital patient's rooms, based on a series of spreadsheets that define a global index, resulting from measurement of spatial, technological and perceptive parameters

vapor liquid equilibrium of binary systems containing low gwp refrigerants with cubic equations of state

Abstract Different Cubic Equations of State (CESs) were used to represent Vapor-Liquid Equilibrium (VLE) of binary systems containing low Global Warming Potential (GWP) refrigerants. The calculated VLE data from some of the widely used CESs were compared with the experimental data collected from the literature. To extend CESs to binary systems, van der Waals one-fluid mixing rules with a single binary interaction parameter were used. Although the deviations between the experimental and calculated values are generally low, a comparison of the results was performed to find the most accurate CES for VLE of the studied binary systems

Energy Performance and Thermal Comfort Assessment of an Educational Building in Northern Italy: The Importance of Climatic Files in Energy Simulations

Energy efficiency and thermal and acoustic comfort play crucial roles in the design and management of educational buildings. The literature underscores their influence on students’ and teachers’ well-being and productivity. Additionally, numerous works emphasise the growing environmental awareness among children attending sustainably designed or adapted buildings. In light of these considerations, the present study aims to evaluate the dynamic energy performance of a school located in Northern Italy, conceived as a Nearly Zero Energy Building (NZEB). The school integrates various technologies, intelligent systems, and renewable sources to reduce energy requirements. A second aspect under evaluation involves using both real and virtual anemometers to generate crucial weather data for energy simulations. Dynamic analyses often rely on traditional meteorological year (Typical Meteorological Year) datasets derived from outdated sources, leading to inaccuracies in representing current climatic conditions, especially in the case of results related to a specific period

Modeling thermal conductivity in refrigerants through neural networks

The thermal conductivity value for a material measures its attitude to transfer heat, though, not many values coming from experimental measurements of the thermal conductivity of different materials are available to the scientific community, which needs accurate model to predict such value from other observations. In this work, we trained and evaluated a Multi-Layered Perceptron architecture for a regression task in which the thermal conductivity for a set of families of refrigerants at the liquid state is predicted from their acentric factor, critical pressure, reduced temperature, and dipole moment, at atmospheric pressure condition. Such model has been proven capable to capture deep regularities over the whole data set and also across different families of refrigerants. Compared to other well-known equations from the literature for the same task, our model significantly outperformed all of them

The QLandQLife Tool

In recent decades, the city and the broader concept of the territory have experienced a metamorphosis: from usable physical resources and controllable, designable space to a new interpretation of the urban system. This system is complex, so the inadequacy of linear planning becomes clear when faced with an increasingly strong need for multiple intelligible responses. The ideal of the city as a “single element” has been substituted by the concept of “system city”, going beyond the model of a city that can be decomposed and simplified to attain an interpretation of the system as a “complex unit
