“…There are individual differences in user's comfort expectation and expectation from the enviornment (Moezzi, 2009). This could result in energy wastage due to inefficent use of thermal control system (Shahzad et al, 2016). Energy wastage due to inefficent control of thermal control system in offices is related to lack of knowledge of system operation and general thermal comfort disagreement amongst occupants.…”

The purpose of this paper is to review the existing literature to draw an understanding of the relationship between indoor environmental quality and occupant productivity in an office environment. The study reviews over 300 papers from 67 journals, conference articles and books focusing on indoor environment, occupant comfort, productivity and green buildings. It limits its focus to the physical aspects of an office environment. The literature outlines eight Indoor Environmental Quality (IEQ) factors that influence occupant productivity in an office environment. It also discusses different physical parameters under each of the IEQ factors. It proposes a conceptual model of different factors affecting occupant productivity. The study also presents a review of the data collection methods utilised by the research studies that aim to investigate the relationship between IEQ and occupant productivity. The study presents a comprehensive discussion and analysis of different IEQ factors that affect occupant productivity. The paper provides a concise starting point for future researchers interested in the area of indoor environmental quality. Keywords: occupant productivity, workplace satisfaction, indoor environment quality, occupant comfortPaper type: Literature review IntroductionHumans spend most of their time indoors, and the majority of the world's population lives in urban areas and work in an office environment (ASHRAE, 1993). There has been a significant global shift in the economy from the manufacturing sector towards the service and knowledge-based sectors which operate in indoor office environments (Haynes, 2008b, World Green Building Council, 2014. Hence, it is becoming important to understand the indoor office environment and the effect it has on occupant productivity. An office environment has a high level of influence on its occupants' productivity (Leaman and Bordass, 1999, Frontczak et al., 2012, Roelofsen, 2002, Mawson, 2002, Van der Voordt, 2004. Past studies on sustainable buildings postulate that green design strategies and technologies enhance the indoor workplace environment. Such strategies/technologies enable the creation of an environment which favours occupants' comfort and performance in both newly built and retrofitted buildings (Romm and Browning, 1994). The majority of the building stock that will exist in 2050 has already been built (2009). Thus, there is a need to investigate the quality of the indoor workplace environment and its relationship to occupant productivity. This paper establishes the state-of-the-art on environmental factors that influence occupant productivity in the office environment. It also highlights and discusses various occupant productivity measurement methods used in indoor environment research studies. This research will help construction industry professionals improve the designs that allow better operation of office buildings along with improving the productivity of the occupants. BackgroundThe research on the direct and indirect effects of indoor environ...

“…Ascione et al [68] evaluated the measures for improving the thermal comfort during the warm season in a naturally ventilated building based on the concept of the cost-optimality. Shahzad et al [69] compared two office layouts with high and low levels of thermal control, respectively traditional cellular (in Norway) and contemporary open plan offices (in UK) and a significant relationship between the preference of user to control the thermal environment and their comfort and satisfaction was identified.…”

“…A research stated that when office workers can control their own indoor environment comfort, health are improved (Raw et al, 1990). On the other hand, from an economic perspective, user control can result in a waste of energy due to inefficient thermal control (Shahzad et al, 2016). There are different employee groups in an office according to their various tasks and they have different work patterns.…”

This paper highlights the importance of considering user satisfaction in office renovation. Userfocused design approach in nearly zero energy office (nZEO) renovation is a way to increase user satisfaction and the value of office quality while meeting energy efficiency goal. The purpose of this paper is to investigate considerable measurement factors affecting user satisfaction. It is also to help better understating about user/occupants' preferences. Measurement factors are studied through literature reviews in relation to user satisfaction of workspaces. The approach aims to give a guide for analysis and evaluation of user satisfaction and to strengthen their importance in an office renovation. The findings present that main measurement factors to increase user satisfaction are not only associated with indoor environmental quality but also with psychological issues such as a feasibility of collaboration, social contact, etc. Additionally, the relationship between measurement factors and hierarchy of user requirements are described.
