Numerical Simulation and Field Survey on Indoor Thermal Comfort for Healthy Building: A Case study on Lingnan Residential Building

Abstract

Due to COVID-19, people spend more and more time indoors. Healthy buildings, therefore, become more attractive to people than ever before. By summarizing specific requirements on relevant standards for healthy indoor thermal condition, this paper adopts numerical simulation and field survey to study indoor thermal comfort with a Lingnan residential building as a study case. After optimizing by building design strategy, the research results show that (1) The numerical simulation method can evaluate the indoor thermal environment, comparing the results from the field survey. (2) The study case did not meet the healthy indoor thermal environment requirements under natural ventilation. (3) By adding sunshades on windows, optimization measure is worked for healthy indoor thermal comfort. (4) Numerical simulation is used for predicting in advance. It helps the designers to solve practical problems.
