Abstract
Buildings are recognized as a key contributor to the climate change mitigation, so they
have been receiving increased attention in recent years in terms of design, performance and
evaluation. Sustainable green buildings can deliver energy and resource efficiency, along
with providing a comfortable, healthy and productive environment for occupants. Office
buildings in all major cities of Malaysia have increased considerably in numbers, especially
in Kuala Lumpur over the last twenty years, and since 2009 that the Malaysia Green Building
Index introduced guidelines for acquiring certifications for sustainable green buildings, there
has been a growing numbers of green buildings constructed in Malaysia in both forms of
residential and non-residential. This study examined the relationships between employees'
satisfaction with five indoor environmental quality (IEQ) criteria at their workspaces, their
overall satisfaction with the whole office, and their work performance, along with examining
the effect of employees' overall satisfaction on their work performance, and the mediating
effect of overall satisfaction on the relationship among IEQ criteria and employees' work
performance, by developing and testing a conceptual framework demonstrating relationships
among these variables. The five IEQ criteria investigated in this study include indoor air
quality, thermal quality, lighting quality, visual quality and acoustic quality
Secondary data analysis was used to investigate the purpose of this study in which data
were obtained from online questionnaire replies of five green building occupants
(employees), and a total of 112 respondents were collected for data analysis. From the
structural model analysis using the PLS path analysis, it was found that satisfaction with all
five indoor environmental quality of indoor air, thermal, lighting, visual and acoustic quality
significantly influenced employees' overall satisfaction with office environment. While only
satisfaction with lighting quality had positive significant effect on employees' work
performance. There was significant relationship among employees' overall satisfaction with
the whole office environment and their work performance. However, testing the mediating
effect of employees' overall satisfaction on relationship between five indoor environment
quality criteria, and employees' work performance revealed that overall satisfaction did not
have mediating effect on relationship between employees' satisfaction with lighting quality
and employees' work performance.
