Standard office building control systems operate the heating, ventilating, and air conditioning on a fixed schedule, based upon anticipated occupancy and use of the building. This study introduces and illustrates a method for integrated building heating, cooling and ventilation control to reduce energy consumption and maintain indoor temperature set points, based on the prediction of occupant b...

This paper makes the assertion that established concepts from thermal comfort research might be used to develop an adaptive comfort model for lighting. By gathering data from a live office environment, we demonstrate the necessity of dynamically-adapted lighting levels in order to achieve both comfort and energy savings. We detail the background and the experimental setup that is used to extrac...

The abundance of super-micron biological and abiotic particles in occupied indoor environments can be influenced by time-dependent changes human-associated emissions building ventilation conditions. Real-time measurements fluorescent aerosol (FAPs) were integrated with a sensing platform to evaluate the influence human occupancy on temporal dynamics living laboratory office. Concentrations size...

Due to the impact of occupants’ activities in buildings, relationship between electricity demand and ambient temperature will show different trends long-term short-term, which seasonal variation hourly variation, respectively. This makes it difficult for conventional data fitting methods accurately predict short-term power buildings at same time. In order solve this problem, paper proposes two ...

A number of heating, ventilation and air-conditioning (HVAC) system vendors and operators have started to implement demand management systems in commercial buildings, yet we contend that the impact of such systems on building performance and occupant comfort is poorly understood. This paper examines such issues, showing the results from demand response experiments in two large office buildings....

The problem of creating the map of an unknown environment by mobile robot control system is considered using range readings obtained by ultrasonic range finder. A grid-based representation of a robot working space is chosen. The goal is the determination of occupied and empty areas in the working environment, which is not a simple problem due the uncertainty introduced by the sensory system. Th...

introduction: the important of comparing performance of hospitals using hospital indicators, has been made the necessary of utilizing of the application model inevitable. this study aimed to compare hospital performance key indicators simultaneity. methods: in this descriptive cross sectional and retrospective study, 31 hospitals of isfahan university of medical sciences were evaluated in 2007....
