PET, air temperature and mean radiant temperature at point where PET of worst case scenario is smaller than for typical summer day. In order to judge the effects of the micro climate on the human thermal comfort, it is necessary to look at the energy balance of the human body, which is influenced by the atmospheric parameters temperature, radiation, wind speed and humidity. In this study the human thermal comfort index PET (physiological equivalent temperature) (Höppe, 1999) is used. Despite the air temperature and the mean radiant temperature being significantly higher in the worst case scenario and the wind speed being the same in both cases, the PET in the worst case scenario is in some areas lower (see Figure 5). As can be seen in PET, air temperature and mean radiant temperature at point where PET of worst case scenario is smaller than for typical summer day.Figure 2

Thermal comfort plays a significant role in encouraging people to utilize outdoor spaces. Therefore, this feature must be analyzed and evaluated in order to be improvised. Computational fluid dynamics (CFD) is an alternative technique that predicts thermal comfort and environmental parameters. Validation of CFD is important to ensure its effectiveness. This study assessed the performance of ENVI-met for its ability to estimate thermal indices (PET) by comparing it to field measurement for various points in a street canyon in Port Said, Egypt, throughout the summer and winter seasons. Except for the limited air velocity correlation, the results presented very good agreement, particularly with respect to the final results of the PET visually curved and numerical values, with an index of agreement value ranging from 0.81 to 0.95. The study's conclusions concern the use of the ENVI-met simulation model as a tool for assessing outdoor thermal comfort.

Achieving environmental sustainability by improving the urban microclimate is a key principle in mitigating the urban heat island (UHI) effect. This study aimed to (a) investigate the outdoor thermal comfort by establishing Heat Index (HI) values to identify thermal hot spots and (b) model green infrastructure possibilities to alleviate UHI in Colombo urban metropolitan in Sri Lanka using ENVImet climate model. Daytime temperature and humidity values of 14 urban locations were collected to determine HI to recognize thermal urban hotspots in Colombo area. A pretested comprehensive random-stratified questionnaire survey has been conducted to appraise the thermal discernment of the general public. ENVImet microclimate model was accompanied to test the temperature reduction levels in different bioclimatic green infrastructure scenarios [Two belts (R1), three belts (R2), four belts (R3), five belts (R4)] in the selected study site. Five sites (Borella, Colombo Fort, Maradana, Wellawaththa, Liberty junction) were identified as thermal hotspots in Colombo metropolitan. HI values were fluctuated within 33.82–40.35 °C range and the highest average day time HI value was observed at Maradana (40.35 °C) and the lowest HI was observed at Thummulla (33.82 °C). Survey results revealed that 89.3% people are affected with thermal uncomfortability and 5% were affected with heat-related skin diseases. Inserting trees into curbsides (R4) reduced temperature remarkably by 2.07 °C in the urban metropolitan. Therefore, the proposed green infrastructure scenario has proved to be the most suitable way to improve the thermal comfort conditions of urban environment, as it can reduce the UHI effects.

Different growth parameters and thermal performances of selected plant species grown on vertical system modules in urban tropical climate have been investigated under the study. Further, outdoor thermal comfort simulation has been modeled by ENVI­met 4.4.5 to investigate the applicability of selected plant species in three different tropical conditions (Colombo Sethsiripaya administrative complex, Matara urban council building and Kandy Urban council building). Sample modular vertical green living wall panels were fabricated by using timber frames (60 × 40 × 5 cm) packed with cocopeat medium with a depth of 3.8 cm. Nine plant species; such as Desmodium triflorum, Roheo spathacea, Centella asiatica, Axonopus fissifoliu, Axonopus compressus, Elusine indica, Dieffenbachiae spp, Tectaria spp, and Bigonia spp were selected for the study. Plant survival percentages, plant height and leaf area index (LAI) were recorded for 8 weeks. Thermal performances were evaluated by considering temperatures at (a) 20 cm distance in front of the green wall, (b) substrate surface of the green wall modules and (c) inside the green wall compared to (d) adjacent bare wall (Control). The highest LAI was recorded from Roheo spp (3.99) followed by Axonopus f. (3.20) and Elusine spp (2.21). Axonopus f. exhibited the highest coverage on the living wall due to high LAI (>1). The highest temperature reduction (5.06 °C) was displayed by Axonopus f. compared to the other species as it covers large extent of the wall. The simulation study of the green walls developed with Axonopus f. signified a possible maximum temperature reduction of 2.07 °C, 3.29 °C and 2.03 °C in Colombo Sethsiripaya administrative complex, Matara urban council building and Kandy urban council building, respectively. Hence, modelling vertical greening with Axonopus f. can effectively enhance the thermal performance in urban context due to their LAI values and the thermal performances.
... Dependendo do número de células que compõe a borda do modelo (Nesting grids) e dos materiais indicados como revestimento do solo, pode haver um sobreaquecimento da área toda, gerando reflexo para a temperatura do modelo e podendo causar mais instabilidades. Bruse (2008, apud Brandão, 2009) sugere a atribuição de solos argilosos para a área da borda do modelo para não camuflar os dados da área principal. Nas simulações realizadas para o presente trabalho, observaram-se duas consequências do dimensionamento da altura e da borda: com mais de 18 células na borda (Nesting grids) e a utilização de solo argiloso nessa área verificou-se a tendência ao rebaixamento da temperatura do modelo resultando em valores inferiores aos medidos e houve a formação de um patamar de temperatura estável a partir do horário de maior aquecimento. ...

... Several researchers have compared ENVI-met results with observed or measured results [9,11,12], indicating that the results are very similar. Some of these studies have looked at local climate with different scenarios of urban greening [12][13][14], global warming effect [15], or urban morphology [16], concentrating on materials that will aid cooling and additional greening. The comparison of the spatial distribution of air temperature and humidity shows that the hotter/drier and cooler/wetter spots predicted by ENVI-met were generally consistent with the observations. ...

The urban heat island (UHI) effect is a global issue that can aggravate global warming (GW) and is a major problem in cities in developing countries like Iran. Local adaptation and mitigation strategies based on available data, tools, and resources in parallel with understanding the necessary level of intervention could be a valuable solution for reducing UHI effects in Iran. In this study, the simulation method ENVI-met was examined as a way of modelling potential strategies to predict UHI. This was done through creating different scenarios for selected areas of the city of Mashhad. In order to assess ENVI-met simulation outputs, the default inputs in both the modelled areas and simulation tool were manipulated. As the aim of this research was to see how much the simulation process could be simplified to suit the resources available in Iran, only ground surface temperature (Ts) was considered. The results revealed using local surface materials have a significant effect on the simulation results. In other words, simulating the model area with local materials shows how unevenly surface temperatures could be distributed. It also indicates an increase in average Ts. However, a long simulation period does not make a significant difference in terms of both average Ts and Ts distribution. Therefore, the recommendation to urban designers is to assign local street and paving materials to their model but to model for a shorter time when computing power is limited. These recommendations apply when urban designers need to examine different scenarios for areas and the size of a neighbourhood.

Urbanization is a global trend determined primarily by excessive population growth, particularly in the developing countries such as Egypt. The configuration and boundaries of urbanization and their model can be observed at a distance of space and time. In this research, geographic information system and remote sensing were used to analyze urbanization and trends in the past 30 years of Mansoura City, which is one of the largest medium-sized cities in Egypt. Four Landsat images, obtained in 1985, 1995, 2005 and 2015, were adjusted and compared using the ArcGIS software. The classified images were analyzed to determine urbanization trends in Mansoura city during the three periods 1985–1995, 1995–2005 and 2005–2015. The results of the change disclosure showed areas and trends in urbanization. The urban area has grown by approximately five times over 30 years. The results showed that the eastern direction was predominant during the periods (1985–1995) and (1995–2005) with 53 and 53% of the city total growth, respectively. During the period (2005–2015), the northern trend was dominant with 38% of the city total growth. This research promotes future urban planning strategies by evaluating temporal spatial transformation and urbanization trends.

The starting point of our study is the Environmental Impact Assessment (EIA) Directive 2014/52/EU, which has strengthened the consideration of climate change and “catastrophic events” in environmental assessments, which includes adaptation-relevant local impacts of climate change on projects due to climate change and also the project's impacts on the global as well as local (urban) climate. This article shows to what extent small-scale simulations of the urban climate can be applied and used within the framework of the environmental assessment of a project. We investigate so called “reasonable planning alternatives” in terms of urban design variants and compare them with their bioclimatic effects (human health as a protection good). The investigated area is located in the City of Bottrop (Germany). The procedure was coordinated with those responsible in the city's administration within the framework of a Living Lab, so that the results can be incorporated into the planning decision-making process which underlines its scientific validity and applicability. By its unique methodological approach, this article brings numerical urban climate modelling together with the legal requirements of European Framework Directives and shows that urban climate studies of reasonable planning alternatives can meet the current legal requirements for environmental assessments.
... Therefore the maximum number of grid cells is quite limited and it is not possible to simulate the micro-climate of whole cities but only single quarters within. ENVI-met uses a uniform mesh with a maximum of about 300*300*35 cells with the horizontal extension ranging between 0.5-10 m and a typical vertical height of 1-5 m (Huttner et al., 2008). ENVI-met carries out the detailed calculation in regards to shortwave and long-wave radiation fluxes with respect to shading, reflection, and radiation from building systems and the vegetation, and it considers the evapotranspiration and sensible heat flux from the vegetation into the air, including full simulation of all physical plant parameters. ...

Thermal comfort in the open spaces is a significant parameter in public mentally and physically healthy. Increased hot days of cities because of the urban heat island is the common phenomenon in cities. This phenomenon effect cites quality by a different aspect such as air quality, Use of fossil fuels etc. therefore, cooling strategies in the urban and urban park's design is one of the important issues of the designers. Urban parks have a significant effect on heat stress mitigation. Persian garden is known for its microclimate effect on pedestrians, so different patterns of Persian garden is selected to be analyzed in terms of thermal comfort condition on the hottest day of summer so far in the dry hot climate of the Shiraz(12 th of July 1998 with the maximum 42°C Ta). In this paper 8 conditions are simulated by Envi-met3.1 to get environment data of these patterns and also the Rayman model is used to calculate the Physiological Equivalent Temperature (PET) as the proper thermal index for outdoor condition. The results demonstrate that alteration of Shortwave radiation both direct and diffuse conditions and mean radiant temperature are affected by both sky view factor and the orientation of the Persian garden. Pavilion location has an important effect in mitigation of the Tmrt by preventing the afternoon powerful sun rays through to the paths in the End.E-W pattern. Therefore, this pattern has a better condition of PET value than the others in Shiraz setting.

Progressive urbanization has a direct influence on both the local and consequently global climate. The spatial development methods of the area require the use of modern computer technologies that support planning decisions by key decision makers. Evaluation of the prevailing microclimate conditions in the external environment is possible using CFD software. In this paper were presented scenarios of the impact of changes in spatial development of the area covered by revitalization process in the most urbanized zone of Lodz. The changes proposed by the authors included two types of simulation input data, i.e. values determined for a typical meteorological year and values of meteorological parameters from the nearest measuring station – Lodz-Lublinek. PMV index enabled to evaluate the thermal comfort of human in an external environment. Conducted research has shown that the more effective solutions were scenarios based on a growth of the green area rather than introduction of water elements within the analyzed public space.

The effect of Urban Heat Islands (UHIs) is becoming increasingly serious in cities. Research on the adaptive planning policies for microthermal environments at the residential block level of cities is thus becoming of greater significance. Based on the cooling effect of planning control elements in residential block areas, the element effects characteristics of water bodies and vegetation distribution on the thermal environment of residential blocks were analyzed by using ENVI-met software. The simulation data analysis showed that the combination of water bodies and vegetation had a synergistic cooling effect. Based on these results, simulations of five effective adaptive measures were carried out step by step in planning scenarios, that is, improving the water bodies with vegetation corridors, the application of high-albedo material on streets, and increasing the number of green patches, east-west green corridors, and north-south green corridors. The results were as follows. First, although each of the five optimization strategies have a certain degree of cooling effect on the entire block, the superposition of each factor had a synergistic effect. Second, different spatial optimization strategies had different cooling ranges for each subzone. The optimization of the north-south green corridor, green patches, and water features corridors were particularly significant for microclimate cooling. The east-west green corridor has a certain influence on a certain range of downwind zones and had an auxiliary cooling effect. The high-albedo material also had a weak overall decrease function for the thermal environment. Finally, the TheeffectofUrbanHeatIslands(UHIs)isbecomingincreasinglyseriousincities.

The optimization scenario planning research provided a method for improving the scientific distribution of adaptation measures in urban residential blocks.
