Evaluation of environmental comfort parameters of workspace in industrial buildings1(Case Study: typical control building of combined cycle power plants)

Due to the superiority of functional requirements of equipment and systems over human requirements in the field of architectural and environmental design of industrial buildings, users have to adapt themselves to the conditions which might be followed by imposed biological and psychological pressures. The present study examines the components and environmental parameters influenced by building features (thermal comfort, lighting quality, office layout, interior decoration, acoustic quality, air quality, cleanliness and maintenance) in typical control building of combined cycle power plants. Using a questionnaire based on Vischerʹs model of environmental comfort regarding peopleʹs environmental perception, the level of users satisfaction with the environmental factors and their self-estimated performance in relation to these factors at the two levels of physical and functional comforts has been determined. The statistical analysis of the results shows that the lack of consideration of the environmental comfort parameters of workspace in the process of architectural design of industrial buildings influences users satisfaction with these factors which is directly related to their self-estimated performance in workplace and consequently their job satisfaction by decreasing them. Taking into account the fact that the amount of impact of various environmental factors on the individuals function was evaluated differently, prioritizing the physical factors in the work place for corrective purposes was finally done using affectability of performance in the degree of satisfaction with any factor.
