With rapid urbanization, the necessity for sustainable development has skyrocketed, and sustainable urban development is a must. Recent advances in computing performance of urban layouts in real-time allow for new paradigms of performance-driven design. As beneficial as utilizing multiple layers of urban data may be, it can also create a challenge in interpreting and operationalizing data. This paper presents an integrated computational framework to measure sustainability, operationalize and interpret the urban form’s performance data using generative design methods, novel performance simulations, and machine learning predictions. The performance data is clustered into three pillars of sustainability: social, environmental, and economical, and it is followed with the performance space exploration, which assists in extracting knowledge and actionable rules of thumb. A significant advantage of the framework is that it can be used as a discussion table in participatory planning processes since it could be easily adapted to interactive environments.

Microclimate is one of the important components of the city environment. Previous researches on public space focused on the influence of spatial forms on user behavior, while ignoring the microclimate elements. This makes it difficult to be authentic of further recreational behavior simulation. The study puts forward a new path to study the influence of microclimate on recreational behavior. Taking the waterfront public space as an example, through the combination of field investigation and microclimate simulation, the influence of wind, temperature, and sunshine environment on residents’ recreational is explored, and the influence will be merged into the recreational behavior simulation. In the process of behavior simulation, the microclimate environment classification evaluation map is used. The study committed to achieve a higher degree of adaption between behavior simulation results and actual conditions. The study introduced microclimate influence factors on the basis of the influence of urban spatial form and service facility elements on behavior activities in the past. Based on that, we optimize the simulation method of urban public space recreational behavior, and improve the accuracy of space diagnosis through showing the impact of microclimate on the behavior of people in the space more objectively and intuitively.

004 – Study of Measurement and Envi-Met Simulation of Winter Night in NanPing Village Under Wet and Cold Microclimate Based on Urban Roughness

This study selects four urban roughness parameters of building density, building FAR, building dispersion ratio, and green rate to study the wet and cold microclimate in the winter night. According to the combination of field measurement and ENVI-MET simulation, the nighttime climate data of 7 measured points and 36 grids were obtained. The significants of the winter night wet and cold microclimate is focused on improving the somatosensory temperature, and this study splits the target into two related directions, one is to extend the duration of comfortable temperature and humidity, another is to expand the comfortable area of temperature and humidity. Coupling analysis of urban roughness and the comfortable ratio was carried out, and 11 relationship lines between urban roughness and nighttime microclimate in NanPing village were found. Using correlation and trend graph analysis, the suitable range of building density is 0.05~0.2, the suitable interval for building FAR is 0.1~0.3, the suitable interval for building dispersion ratio is 6~8, and the suitable interval for green rate is between 0.6~0.8. Using these laws, the design strategy for NanPing Village’s future development from three directions is provided. It also provides a solution to achieve a low carbon, sustainable built environment.

202 – Analytical Study of the Impact of Greenery and Public Space Distribution on Land Surface Temperature in Mid-Size Cities of Poland
Tuesday 30 March, 14:45, Session 3C

The focus of the article is the impact of urban geometry and greenery on the surface temperature in a city and the Urban Heat Islands (UHI) effect. The research problem discussed in the article is to define optimal combination of such parameters as urban geometry, greenery and the LST to enhance the temperature comfort and reduce the UHI effect. The methodology combines CAD and GIS environments. Vector data of 1:10000 scale, from the National Database of Topographic Objects (BDOT10k) is used to analyse urban structure. GIS data include rasters derived from remote sensing: Land Surface Temperature (LST), Digital Surface Model (DSM) and Digital Terrain Model (DTM). The analysis covers areas in Szczecin and Gdynia, two mid-sized cities in Poland. The results indicate a more distinct dependence of LST on greenery parameters than on buildings. The main contribution of the article is the development of a uniform data grid based on CAD and GIS data, allowing for an objective analysis of the city’s temperature comfort based on the parameters of buildings, greenery and LST.
