Problems solved by technology

The current technologies to guide the division of outdoor suitable sites and functional space placement in residential areas are mostly related to national or local planning and design standards, which are difficult to reflect the regional differences created by urban microclimate, and a large number of qualitative expressions are also difficult to intuitively guide or constrain the actual situation. project construction
The conventional method of dividing suitable activity space based on the duration of sunshine ignores the comprehensive influence of wind and thermal environment on the site, and cannot explain the influence and adjustment effect of functional facilities on the outdoor micro-environment in the design scheme; the current technology is mostly based on the simulation of a single meteorological factor The plane spatial distribution characteristics cannot fully reflect the three-dimensional temporal and spatial differentiation of multiple meteorological factors

Embodiment

[0027] The optimal implementation case of the functional facility configuration method based on the community microenvironment and outdoor comfort simulation includes the following steps:

[0028] Step S1, using the meteorological data of the local summer solstice (June 23) and winter solstice (December 21) as the background boundary, using the computational fluid dynamics model (Computational Fluid Dynamics, CFD) to carry out physical space modeling and micro Environmental simulation to calculate the hourly (that is, 24 hours a day) planar spatial distribution map of temperature and humidity, wind speed and Tmrt (average radiant temperature) at the pedestrian height (for example, 1.5m above the ground); Meteorological parameters such as temperature and humidity, wind speed and mean radiant temperature (Tmrt). The simulation software can use ENVI-met, which can meet the demand for detailed modeling of vegetation, land surface, and buildings in the community, and characterize t...

Abstract

The invention relates to the field of community functional facility planning, and particularly discloses a functional facility configuration method based on community microenvironment and outdoor comfort simulation. Microclimate parameters such as temperature and humidity, wind speed and average radiation temperature of an open space of a community are generated through microenvironment simulation, and a physiological equivalent temperature is further obtained through human body physiological index simulation; dividing the outdoor activity site of the community into a suitable activity area, a more suitable activity area and an unsuitable activity area according to the thermal sensation accumulated duration corresponding to the physiological equivalent temperature; according to the influence degree of the space carrier of the functional facility on the microenvironment parameters, the optimization of the unsuitable or more suitable activity area and the space comfort of the building roof is realized. According to the method, three types of outdoor activity areas are divided according to physiological equivalent temperature values through cell-scale microenvironment simulation, and optimization of microclimate of a relatively suitable activity area is realized by establishing four space carriers, so that the microclimate is converted into a suitable activity interval, and the activity duration of outdoor comfortable feeling of residents is prolonged.

Description

technical field [0001] The invention relates to the field of functional facility planning in a community, and specifically discloses a method for configuring functional facilities based on the microenvironment of the community and outdoor comfort. Background technique [0002] Urban development is transforming from incremental expansion to stock renewal, and community planning places more emphasis on comfortable environment and suitable space. The current technologies to guide the division of outdoor suitable sites and functional space placement in residential areas are mostly related to national or local planning and design standards, which are difficult to reflect the regional differences created by urban microclimate, and a large number of qualitative expressions are also difficult to intuitively guide or constrain the actual situation. project construction. The conventional method of dividing suitable activity space based on the duration of sunshine ignores the comprehe...
