Spatial environment design and comfort simulation of high-latitude building bottom based on geological conditions

Abstract

In order to solve the situation that the temperature in the high-latitude area is large and the space comfort of the bottom of the building is poor, the bottom space environment of the high-latitude building based on geological conditions is designed, and the comfort of the space environment is simulated. The numerical simulation technology is used to simulate the temperature information of the bottom space of the building, and the temperature, velocity, and humidity fields of the space air at the bottom of the building affected by the geological conditions are obtained. Based on the characteristics of the high-latitude space environment, the design is applied to the single-core bottom space and the multi-core bottom space. The space environment at the bottom of the high-latitude building is divided into functional partitions of the bottom space; the outdoor open space thermal comfort model of Actual Sensation Vote (ASV) is used to simulate the wind environment, radiation distribution, temperature, and humidity distribution and simulate the comfort of the space environment at the bottom of the building. The analysis of the experimental results shows that the weather condition at 8:00 am is the most comfortable time for human body to feel. At this time, the thermal feeling in most areas of the indoor space is moderate, which shows that the method can accurately simulate the comfort of the space environment at the bottom of the building from the perspective of radiation distribution, wind speed distribution, and thermal comfort distribution, and the designed space environment function layout at the bottom of the building is reasonable.
