How does indoor environmental quality in green refurbished office buildings compare with the one in new certified buildings?

Decent quality of indoor air is important for health and wellbeing of building users. We live, work and study in indoors of various types of buildings. Often people are exposed to pollutants at higher concentrations than these that occur out-doors. Continual investigation of indoor air quality is needed for ensuring comfort and healthy environment. Measuring and analysis of occurrence of physical, chemical and biological factors is the first step for suggestion of optimization measures. Inside school buildings there are often inadequate indoor climate conditions such as thermal comfort parame-ters or ventilation. The aim of this study was determination of indoor environmental quality in selected offices in the building of elementary school in Slovakia. The values of operative temperature were not within the optimum range of values for the warm period of the year in one of the monitored offices. The intensity of illumination was lower in the two offices. Low levels of particulate matters were measured except the one office where permissible value was exceeded by 7.6%.

The One

This study investigates the indoor environmental quality (IEQ) responses from occupants living in very small residential units that are unique to Hong Kong. Through the changes in environmental parameters, including thermal, indoor air quality, visual and aural, the study demonstrates that the overall IEQ acceptance in these units is different from the one in general residential building environments. Results show that occupants of these units are more sensitive to warmth and operative temperature change as compared to occupants of general residential buildings. A small variation of thermal acceptance suggests that the small unit occupants have already developed certain degree of tolerance to hot conditions. The adaptation to the reality of a hot environment is also reflected in the overall IEQ acceptance. It is believed that very small space residents have developed tolerance and adaptation to an unchangeable reality, changing environmental conditions does not necessarily alter their acceptance of individual IEQ aspects and overall IEQ.

The Impact

Indoor environmental quality (IEQ) could influences employees' satisfaction and performance in office buildings. Previous research have suggested that factors such as gender, age, proximity from a window could influence employees' perceived satisfaction with IEQ. This study as a part of an ongoing research attempts to investigate the impact of workspace location on employees' satisfaction with IEQ parameters and overall satisfaction with personal workspace within office buildings in Cairo. Employees' subjective evaluation of satisfaction with IEQ parameters were collected using a questionnaire as a post occupancy evaluation survey. Responses were collected and quantitatively analysed using software package used for statistical analysis (SPSS). Diversity in levels of satisfaction among employees within the same building was found highly sensitive to their workspace location. Building orientation and external views could influence employees' satisfaction with IEQ parameters and overall satisfaction with personal workspace. Employees with highest perceived satisfaction with IEQ parameters and overall satisfaction with personal workspace seem to prefer their workspaces to be located on the ground floor, away from a window, either in the middle of the building or on the southern façade and not overlooking the courtyard. The study recommends that Leadership in Energy and Environmental Design (LEED) certification criteria should reconsider employees' satisfaction with IEQ parameters in developing IEQ credits and LEED certification process.
