indoor air quality is a general concept that specifies to air quality of buildings and is related to health and relaxation in there. this index contains removal of all contaminants for example microbial, gas types, particles, etc., and suggests remedial approaches toward refreshing the building air and air circulation in these constructions. in this article we study indoor air quality index (ia...

BACKGROUND The pursuit of efficiency and the permeation of communication technologies in modern workplace have increased prolonged sitting and physical inactivity among the white-collar workforce. Physical inactivity is a major risk factor for developing various chronic diseases and obesity. OBJECTIVE This study intends to understand the impact of physical environment on both voluntary and im...

Humans apparently differ greatly in their sensitivity and tolerance to tobacco smoke, thereby creating conflicts in the workplace. Resolution of conflicts in a large office complex at the authors' institution required an objective measure of smoke levels. A gas chromatographic technique was devised for collection and analysis of nicotine concentrations in the building air as an indicator of tob...

This study examines the theoretical and practical implications of ranking teachers with a one-dimensional metric when teacher effectiveness varies across subjects or student types. We document the empirical failure of standard value-added assumptions of teacher input homogeneity, but demonstrate that previously suggested teacher firing policies still improve student welfare, although they resul...

This article introduces two system models to simulate the energy performance of the temperature and humidity independent control air-conditioning system (THICS) and the conventional airconditioning system (CAS). The energy performance comparison includes three parts of cooling resource, transportation system and terminal devices. A typical office building with these two different systems is num...

The spatial organization of the workplace affects the work going on there. The technology used, changes the work practice. This paper describes a design process where different aspects of workplace design for project-based office work have been combined into one multi-stakeholder project, integrating the spatial aspects, the furniture, the information technology, and the IT-services that are co...
