This study utilizes ENVI-met simulations to examine the effectiveness of nature-based urban design strategies in enhancing outdoor thermal comfort for senior citizens during Mediterranean heat waves. The research focuses on a high-density, post-refugee neighborhood Greater Athens, assessing both baseline and optimized scenarios featuring mature trees water elements. Simulations conducted July 23, 2023—the hottest recorded day year—demonstrate substantial reductions...

The present study deals with the estimation of human thermal sensation zones in a Mediterranean climate (Athens). Field monitoring along field surveys leading to database 2313 questionnaires were carried out three open urban areas. Thermal conditions analysed under influence air temperature, relative humidity, solar radiation and wind speed. first defined using temperature as single parameter affecting sensation. Logistic regression was appropriately used define each zone. then determined...

The present study investigated the cooling effect of extensive green roofs and façades, at pedestrian level, a Mediterranean densely populated neighborhood. ENVI-met environmental model was employed to simulate microclimatic environment on typical summer day. Thermal conditions area were evaluated based air temperature thermal stress scale UTCI (Universal Climate Index). Three mitigation strategies developed ameliorate in examined focusing efficacy roofs, synergetic façade roof. strategies’...

Today, high-density building areas, along with low albedo construction materials and a lack of green spaces, have led to higher urban temperatures. Climate change significantly intensifies the magnitude overheating frequency extreme heat events is expected increase over time. The aim this research showcase new insights into cooling effects elements layouts in residential area consisting several blocks Mediterranean city (Athens). microclimatic model ENVI-met was applied simulate thermal...

The present study investigated the potential cooling effect of green roofs and façades on a residential neighborhood in Athens during typical summer day. numerical model ENVI-met was employed to simulate thermal environment area at existing configuration. Then, different design interventions focusing application façade rooftops buildings were developed order evaluate amelioration adverse conditions. Thermal conditions assessed based basic meteorological parameter values well-known indices...

The study examines the effectiveness of various design strategies in alleviating impacts heatwaves Mediterranean region, focusing on a densely populated post-refugee urban area Greece. By analyzing five different scenarios, aims to identify most efficient approach mitigate thermal stress outdoors. scenarios include changes albedo values and coatings alterations number type trees. methodology includes literature review, field work microclimate simulations with use ENVI-met 5.6.1. evaluates...

Abstract This current work attempts to explore the temperature’s variability through selection of indicators that refer increases and decreases three typical values daily temperature (mean, maximum, minimum). The primary meteorological data has been used come from station Hellenic National Meteorological Service in Tatoi, period 1955 2001. In total, nine were developed; time series number days recorded with decrease, increase or stability day-by-day characteristic value examined annually...

Abstract The current study attempted to investigate the temperature’s variability through selection of indicators that refer mostly increases and decreases three typical values daily temperature (mean, maximum, minimum). primary meteorological data has been used come from station Hellenic National Meteorological Service in Tatoi, time period 1955-2001. series maximum mean number days with a continuous increase or decrease was investigated seasonally annually. In addition, switches...

This study investigates the potential for passive cooling patterns inside urban fabric in Mediterranean climate city of Athens (Greece), especially with regard to quantify air temperature reduction and thermal comfort amelioration at neighbourhood scale. Using both field measurements an microclimate simulation model, we assessed warming various sites residential neighbourhood. Results show that, under conditions, design elements such as wooded courtyards appropriately oriented galleries have...

Urban public space comfort is vital for enhancing the quality of life and perceptions livability, especially as climate change increasingly impacts outdoor thermal environments. This study investigates use ENVI-met, a 3D microclimate simulation tool, to assess concerning demographic factors like age gender. While ENVI-met often used analyze urban microclimates, there limited research on its application simulating heat emission variations across different groups. The findings highlight...

Urban public space comfort is essential for improving quality of life, particularly as climate change affects outdoor thermal environments. This study utilizes ENVI-met, a 3D microclimate simulation tool, to assess concerning demographic factors such age and gender. The findings indicate significant disparities in stress vulnerability among groups. On the hottest day July 2023, at 10 a.m., children’s PET values were approximately 2 °C higher than those other By 3 p.m., females experienced...
