It is important to improve residential thermal comfort in the high dense cities, in which wind environment is crucial. Waterside buildings take an advantage of micro-hydrological-climate in summer that should be used to enhance residential thermal comfort especially in the subtropical region. In order to propose design approaches according to the outdoor thermal comfort of the waterside residential, a case study of Shenzhen She Kou residential district has been made. It focused on various factors that could have influence on wind environment for improving thermal comfort. Using wind velocity ratio (ΔRi) criterion, factors of building development volume, building direction and layout pattern, open space arrangement etc. have been broadly explored using FLUENT simulation. To planning parameters, the Floor Area Ratio (FAR) is significantly influence wind environment, the smaller FAR is better. To the vertical layout of the buildings, multi-storey layout and multi-storey & sub high-rise mixed layout would provide better wind environment. To the horizontal layout, the determinant is better than the peripheral. Other factors such as the buildings’ direction towards the road, buildings’ height, and open space setting, have influence on wind environment yet. In general, the more benefit of design layout for wind breezing, the better wind environment it could get

The present study is based on the assumption that the urban heat island (UHI) mitigation appears compelling and urgent in dense cities. To the above thematic area, recent redevelopmental interventions of open space for the microclimatic improvement and thermal comfort have been made through national and international programs at neighborhood scale (local area). One of these recovery processes is the case study of Pavlou Mela in the Greek context, which in the present discussion, focuses on the microspecific investigation through quantitative analysis of the eleven points distributed in the area of the intervention, extrapolating comparative considerations of different configurative factors post-operam. The results of this analysis tend: (i) To identify the degree of accuracy of the two most applied software packages in the scientific community (ENVImet Pro and Rayman Pro) through microclimatic parameters, namely air temperature (Ta) and surface temperature (Ts) comparing them with in-situ measurements; (ii) to evaluate the thermal sensation of man correlated with the mean radiant temperature (Tmrt) by verifying the actual improvement of thermal comfort outdoor with the index, physiologically equivalent temperature (PET).

Campus Building

Campus building was a place to accommodate various educational activities, which were both carried out indoors and outdoors. The environment, including the building and its exterior, provided thermal comfort that was influenced by the context, such as the mass of the facility, vegetation, and constructing envelope materials. The microclimate also influenced the environment, such as temperature, wind speed, and humidity. This study aimed to investigate the outdoor thermal comfort of campus building in urban area during summer, while also identifying the influential factors. This research referred to a case study, examining the thermal quality of the educational building environment using ENVI-met software, based on the Predicted Mean Vote (PMV) index as an indicator of outdoor thermal comfort, in Universitas Kebangsaan (UK). The results showed that the outdoor environment had low thermal comfort conditions during the day, as it also had different thermal satisfactory situations, due to differences in physical characteristics in each zone. This characteristics included, (1) The SVF determinant as indicators of the shading factor should be supported by the presence of vegetation and the use of pavement material, (2) Although the wind speed factor does not really affect the thermal comfort in the outdoor space, the interconnection between open gaps is likely to make breeze distribution in the area better. This study offered direction for campus planning, in order to maintain the optimal capacity of the natural environment, such as (1) Strategizing to create a better shadowing factor in the outer space, which was supported by controlling the use of pavement materials, (2) Directing the density of buildings by making open spaces more permeable, in order for better wind distribution in the area. From this study, the campus current conditions and future design development potential was also observed.

Dense settlements in urban areas are one of the problems in DKI Jakarta. RT.03 / RW.01 Kel. Petukangan Utara, Kec. Pesanggrahan Jakarta Selatan is one of the densest settlements in DKI Jakarta which is located side by side with Universitas Budi Luhur. Based on SNI 03-1733-2004, the level of population density in the region is included in the category of High Density. This can be seen from the houses lined up along the road with little provision of Green Open Space. The community develops the need for building area by maximizing the area of land for building. This impacts the lack of air circulation in accordance with SNI-14-1993-03 about the thermal comfort area of buildings which are conditioned for Indonesians, as well as the lack of lighting in accordance with SNI 03-6575-2001 regarding illumination standards for the light of a room.With thermal comfort and illumination that is not in according to standards in the region, a Community Service activity was held by the Faculty of Engineering of the Universitas Budi Luhur to add community knowledge about how to make thermal comfort and illumination in homes using energy efficient. Thermal comfort can be fulfilled by making vertical greening on limited land, While the comfort of illumination can be fulfilled by using LED lights. The activity uses community empowerment methods, so that the community can independently make vertical greening in their respective homes and know the benefits for thermal comfort and can use LED lights in their respective homes and know the benefits to save electricity. The results of the Community Empowerment Towards Energy Saving Settlements at RT.03 / RW.01 Kel Petukangan Utara Kec. Pesanggrahan Jakarta Selatan, is that the region has vertical greening as a natural air conditioning system and uses an LED lighting system as an energy efficient lighting.

Within the scope of the study, thermal comfort analysis was performed using the ENVI-met program of the Misak-ı Milli Square in Safranbolu, and it was determined that the thermal comfort perception of the square as slighty warm-warm. For this reason, a new design proposal has been submitted for the square. In the proposal, the green ratio and the number of trees was increased, the type and location of the trees was changed. The flooring materials was replaced with a stone covering with a higher albedo and new functional suggestions were made for the square. As a result of the thermal comfort analysis of the new proposal, the thermal comfort perception in the square was neutral and the thermal dissatisfaction rate was reduced below 14.5%. In result of the study, it was underlined that the ratio of green areas and the tree type, number and location that constitute it and the choice of flooring materials are important parameters in providing the thermal comfort of the square.
