Building performance indicators are widely used to guide building design and track benchmark operational performance. Traditional mostly focus on the energy efficiency perspective. As occupants primary service recipients in residential most commercial buildings, their comfort wellbeing crucial. This study first identified significant attributes of occupant-centric key (KPIs) analyzed diverse fa...

OBJECTIVE Public concern has arisen about the reliability of front air bags because Fatality Analysis Reporting System (FARS) data indicate many nondeployed air bags in fatal frontal crashes. However, the accuracy of air bag deployment, the variable in question, is uncertain. This study aimed to provide more certain estimates of nondeployment incidence in fatal frontal crashes. METHODS Fatall...

INTRODUCTION Injuries and fatalities due to large truck and other vehicle crashes have decreased over the last decade, but motor vehicle injuries remain a leading cause of death for both the working and general populations. The present study was undertaken to determine semi truck driver and sleeper berth passenger injury risk in a moving semi truck collision using a matched-pair cohort study. ...

Injuries will inevitably occur when restraining loads are exerted on a car occupant by a seat belt during a crash. This study investigated the nature, frequency, and severity of such injuries to the chest and abdomen. Vehicle, occupant, and injury details were obtained from accidents occurring in the Midlands of England. The sample was chosen with emphasis on fatal and serious injuries while al...

Background and purpose: Elevated CO2 rate in a building affect the health of occupant. This document presents results of an experimental analysis conducted in 50 offices located in 12 buildings with different layer in Cameroon (Yaounde). This study took place in 2012, during the dry and the rainy seasons. The main goal is to show the influence of the building structure, the ventilation and the ...

Occupant behavior based on natural ventilation has a significant impact building energy consumption. It is important for the quantification of occupant-behavior models to select observed variables, i.e., features that affect state window opening and closing, consider machine learning are effective in predicting this state. In study, thermal comfort was investigated, data were analyzed 30 houses...

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....

Low frequency footfall noise ("thudding") is a common source of complaints in lightweight (timber) joistframed multifamily projects. Previous work by the authors has indicated that the low frequency impact sound pressure levels (LFISPL) from a standard ISO tapping machine are highly correlated with occupant reaction. It remains to translate the raw LFISPL data into a useful single number metric...
