Comprehensive renovation and effect analysis of indoor environment in existing buildings —Taking a medical building as an example

Takes a medical building as an example to demonstrate the key technical renovation methods formed by the “13th Five-Year Plan” national key R & D plan “Research and demonstration of key technologies for indoor physical environment improvement in public buildings”. Through investigation and test on the current status of indoor thermal and humidity environment, noise environment, light environment and air quality in existing buildings, analyses the key issues in the indoor environment. Forms a targeted technical transformation plan and operational management recommendations by analysing the key factors and renovation technology principles affecting indoor air distribution, noise and PM2.5 pollution. Summarizes the steps and ideas for the indoor environment renovation of existing buildings. Analyses the renovation effect of the project by the theoretical calculation and simulation method.
