Plug load and Heating Ventilation and Air Conditioning (HVAC) systems are the two largest energy consumers in commercial buildings. The use of the 2 systems is closely related to occupant behavior and schedule. It is significant to learn the occupant behavior pattern and predict occupancy schedule for controlling the systems to save energy. A data mining study is performed on the office applian...

To study the indoor climate, the psychosocial work environment and occupants' symptoms in offices a cross-sectional questionnaire survey was made in 11 naturally and 11 mechanically ventilated office buildings. Nine of the buildings had mainly cellular offices; five of the buildings had mainly open-plan offices, whereas eight buildings had a mixture of cellular, multi-person and open-plan offic...

In this paper, we develop an agent-based model which integrates four important elements, i.e. organisational energy management policies/regulations, energy management technologies, electric appliances and equipment, and human behaviour, to simulate the electricity consumption in office buildings.

Surveys in several office buildings have shown that crowded work places, job dissatisfaction and physical environment are the main factors affecting productivity. the data was produced and analyzed using occupational stress indicator in conjunction with the analytical hierarchical process. thermal problems, stuffiness, sick building syndrome factors and crowded work places were most frequent co...

The three connected buildings of the former Suffolk Manufacturing Company in Lowell, known as Mills Nos. 5, 6 and 8, were built in 1862 (No. 5) and 1880 (Nos. 6 and 8), at a time when the city of Lowell was one of the predominant centers of the textile industry in the United States. Located within the Locks and Canals National Register Historic District, this impressive complex of mill building...

INTRODUCTION Health benefits of regular participation in physical activity are well documented but population levels are low. Office layout, and in particular the number and location of office building destinations (eg, print and meeting rooms), may influence both walking time and characteristics of sitting time. No research to date has focused on the role that the layout of the indoor office e...

The current study analyses the performance of deep sand filtration of greywater from an office building and the performance of a combined physicochemical process comprising of coagulation, sedimentation and filtration. Raw greywater quality exhibited very high variability with average turbidity of 35 NTU, and TSS, COD(t), and BOD of 45, 240, 75 mg/l respectively. The stand-alone filter removed ...

It is desirable to ensure that the thermal comfort conditions in offices are in line with the preferences of occupants. Controlling their offices correctly therefore requires the correct prediction of their thermal sensation which is often determined using the ISO 7730 norm. The latter defines the predicted mean vote, i.e. the mean thermal preferences of an average group of people, based on a n...

OBJECTIVE To examine the relation between ventilation rate and occurrence of symptoms of the eyes, nose, throat, and skin as well as general symptoms such as lethargy and headache, often termed the sick building syndrome. METHODS A cross sectional population based study was carried out in 399 workers from 14 mechanically ventilated office buildings without air recirculation or humidification,...
