Embodiment 1

[0095] In order to meet the needs of building natural ventilation, the present invention proposes a design method for building natural ventilation; traditional green building analysis software is not only complicated to operate, but also requires too much knowledge of green buildings, which is not conducive to designers to carry out green building correctness. At the same time, the simulation analysis software cannot be overlapped with the architectural design software, and the work often brings repeated modeling work, which leads to the lag of the current green building design. Butterfly, a software based on the grasshopper platform, successfully links the analysis software with the architectural design software, and directly feeds back the simulation results through real-time modification of the architectural model. At the same time, the grasshopper software is used to directly parameterize the model, which directly reduces the design process. The workload of repeated modelin...

Embodiment 2

[0126] The present invention is based on a climate-adaptive natural ventilation parametric design and dynamic (unsteady state) evaluation method, selects Wuhan City located in hot summer and cold winter regions as the climate background, and takes the indoor natural ventilation design and evaluation of high-rise residential buildings as the object;

[0127] Step 1: Extract the meteorological data of Wuhan City and select the calculation period, estimate the average wind speed by empirical formula; select the evaluation model of natural ventilation potential, calculate the hours and effectiveness of natural ventilation in Wuhan, and summarize the unsteady state of natural ventilation Boundary conditions;

[0128] Step 2: Take the indoor thermal and humid environment of the building as an unsteady environment, and use the relative thermal index RWI and heat loss rate HDR to evaluate the indoor thermal and humid environment;

[0129] Step 3: Determine the evaluation index for eva...

Abstract

The invention belongs to the technical field of passive energy-saving design of buildings, and discloses a natural ventilation parameterization design and dynamic analysis method based on climate adaptability, which comprises the following steps of: selecting a corresponding climate database and extracting related meteorological parameters of a target city; calculating the hour number and effectiveness of the available natural ventilation of the target city all the year round through the calculation model of the natural ventilation potential, and summarizing the unsteady state boundary conditions of the natural ventilation according to the unsteady state characteristics of the natural ventilation; obtaining a dynamic heat and humidity range in combination with the building dynamic heat and humidity adaptation model; constructing a parameterized design model; and obtaining a dynamic evaluation result through calculation, simulation and analysis in combination with ventilation evaluation indexes and performing optimization. Based on Butterfly software of a Grasshopper platform, a simulation result of natural ventilation is directly fed back to a building model, real-time adjustment of the model is achieved through a parameterization means, and the workload of repeated modeling in the design process is directly reduced.

Description

technical field [0001] The invention belongs to the technical field of building passive energy-saving design, and in particular relates to a parametric design and dynamic analysis method for natural ventilation based on climate adaptability. Background technique [0002] The 2021 research report of the Building Energy Conservation Research Center of Tsinghua University pointed out that as my country develops from north to south, the number of hours of opening windows in residential buildings increases hour by hour throughout the year, and the seasonal difference becomes smaller. Residents’ habit of opening windows for ventilation is basically open whenever possible , mainly affected by the outdoor weather conditions, the habit of opening windows for ventilation is a living habit; after testing, the indoor formaldehyde concentration is the highest in summer, and about 35% of the residential buildings in the country have formaldehyde exceeding the standard limit. significantly i...
