The effect of China's three-star green building rating standard on occupant satisfaction requires further research. This article presents the results of a comparative analysis of occupant satisfaction levels of certified and non-certified three-star office buildings in relation to the building as a whole, building performance and several indoor environmental quality parameters (IEQ) in the different seasons (cold zone, hot zone, summer-cold winter zone and hot summer-warm winter zone). Furthermore, a comparative analysis was carried out to determine the effect of different evaluation tools on occupant satisfaction, including LEED and BREEAM certified buildings.

Survey data from the CBE (Center for the Built Environment at the University of California, Berkeley) was used to analyze occupant satisfaction in LEED-certified buildings. Huizenga et al (2005) analyzed occupant satisfaction in 16 LEED green buildings and 9 self-designated green buildings and revealed that users in green buildings were statistically significantly more satisfied with the building and workspace, the indoor air quality, cleaning and maintenance and thermal efficiency. comfort, as well as lighting and acoustics. Research conducted by Altomonte et al (2016) on the analysis of satisfaction with building and workspace and different IEQ parameters in BREEAM and non-BREEAM certified buildings in the UK revealed that BREEAM certification does not have a significant effect and practically relevant on occupant satisfaction with buildings. An online questionnaire survey was conducted in all three climate zones: cold zone (Beijing), hot summer-cold winter zone (Shanghai and Chongqing), and hot summer-warm winter zone (Shenzhen) to assess satisfaction levels of occupants of three-star and non-three-star office buildings. The questionnaires were sent electronically to provide details on their basic information (gender, age, job), IEQ in different seasons (temperature, humidity, air quality, lighting, acoustics) and building performance (building in general, maintenance of the building, cleanliness of the building, colors, comfort of the furnishings). A statistical analysis was performed to calculate the mean and median values ​​of occupant satisfaction with IEQ in summer, transition season and winter. The satisfaction ratings of all occupants in the dataset were averaged, including parameters such as temperature, air freshness, air cleanliness, natural lighting, artificial lighting, acoustic environment, productivity, furniture comfort, colors and texture, space, visual privacy, building cleanliness, maintenance and construction in general.
