Productivity in buildings: The 'killer' variables

Losses OT gains of up to 15% of turnover in a typical office organization might be attributable to the design, management and use of the indoor environment. There is growing evidence to show that associations between perceived productivity and clusters of factors such as comfort, health and satisfaction of staff. Some of the management, design and use characteristics which contribute towards better energy efficiency also help productivity, thereby helping to close the loop on a potential 'virtuous' circle. Unfortunately, the vast majority of occupied buildings do not have these self-reinforcing qualities and many are unmanageably complex. This paper examines which factors within the control of building designers and managers best contribute to human productivity - the 'killer' variables of the title.
