“…Lobaccaro and Acero [39] found that among the scenarios they simulated to reduce temperature, the highest reduction of temperature was achieved by combining trees and grass. The capability of grass in improving thermal comfort in winter is also shown by Afshar et al [50]. Their study found that applying more percentage of deciduous trees and grass in a park design will increase temperature and improve thermal comfort in winter.…”

Research on urban heat mitigation has been growing in recent years with many of the studies focusing on green infrastructure (GI) as a strategy to mitigate the adverse effects of Urban Heat Island (UHI). This paper aims at presenting a review of the range of findings from GI research for urban heat mitigation through a review of scientific articles published during the years 2009-2019. This research includes a review of the different types of GI and its contribution for urban heat mitigation and human thermal comfort. In addition to analyzing different mitigation strategies, numerical simulation tools that are commonly used are also reviewed. It is seen that ENVI-met is one of the modelling tools that is considered as a reliable tool to simulate different mitigation strategies and hence has been widely used in the recent past. Considering its popularity in urban microclimate studies, this article also provides a review of ENVI-met simulation results that were reported in the reviewed papers. It was observed that the majority of the research was conducted on a limited spatial scale and focused on temperature and human thermal comfort.

“…As such, the measurement of temperature, relative humidity, and wind velocity in terms of various scenarios in planting design, types, and ratios of vegetation showed that in a scenario of evergreen trees, humidity was relatively high while temperature and wind velocity decreased. However, simulated grass covered parks and deciduous trees showed higher temperature and wind velocity [21]. The authors stressed the possibility of improvement of winter thermal comfort when considering a proper planting design as an important step in order to achieve citizens' satisfaction in terms of thermal comfort [21].…”

In recent decades, the steady increase of energy consumption from building construction and operations cause atmospheric pollution and significant financial burden, mainly due to the high costs imposed from energy production. This study examines ways under which modern designs of a building can be applied on construction and domestication while following conventional methods of construction, compared to a building that has been constructed and domesticated under bioclimatic architecture. Particularly, two buildings were investigated in terms of the energy consumption incurred, being built on the same seaside area and period of construction and at adjacent plots of the same distance from sea for ease of comparison. The first building (A1) was constructed under the principles of bioclimatic architecture, being also facilitated with green and smart technologies. The second building (A2) was constructed under conventional construction techniques. The energy efficiency of both buildings was calculated by the “TEE KENAK” software, while specific parameters were recorded. Energy classifications of both buildings were valued and a proposed scenario and interventions unveiled the energy classification upgrading from A2 to A1. Our analysis revealed, as also found in the literature, that during thermal energy oscillating conditions, corresponding relative humidity stresses were observed, indicating that the vapor pressure handling should be taken into account towards comfort. The preliminary incremental cost evaluation and comparison of A1 and A2 energy upgrading under the criterion of simple payback period were critically discussed.

“…HTC is the condition of mind that expresses satisfaction with the thermal environment and is assessed by subjective evaluation (ASHRAE). Many studies have been conducted to evaluate the level of thermal comfort inside and outside buildings [12][13][14][15][16][17][18][19][20][21][22][23]. More than 100 indices have been developed [24] some of which are commonly used in thermal comfort studies [25], including Predicted Mean Vote (PMV) [26], Physiological Equivalent Temperature (PET) [27], Universal Thermal Climate Index (UTCI) [28][29][30] and Standard Effective Temperature (SET) [31].…”

This study assesses Human Thermal Comfort in two selected areas: a Green Infrastructure (GI) area represented by a garden and a high-rise building area, in the Central Business District (CBD) of Melbourne, Australia. Three-dimensional microclimatic modelling software, ENVI-met version 4 was used to simulate the microclimate. The indices of Predicted Mean Vote (PMV), Physiological Equivalent Temperature (PET) and Universal Temperature Climate Index (UTCI) were used to quantify the level of thermal comfort in the research areas. The simulation results showed that at midday, the difference in temperature between the garden area and the high-rise building area was approximately 1°C. Increasing temperatures at midday led to a change in the level of thermal comfort for both the areas, even though it was not significant. In general, the thermal perception in the GI area was slightly ‘cooler’ than in the high-rise building area. The results of the study indicated the important role of GI in improving the thermal comfort in urban areas.
