In China, existing buildings comprise more than 40 billion square meters, most being of high energy consumption. A substantial reduction in electrical energy costs could be obtained through greater use of daylight. Daylight varies widely due to the movement of sun, changing seasons and diverse weather conditions. Custom static daylight assessments, simulations represent only one time of the yea...

The research presented in this paper reports an analysis of daylight in three offices with different exposures and characteristics located in Naples (Italy). The goal was to fully investigate daylight characteristics, also considering the circadian impact of daylight entering these offices, with the hope to develop guidelines to better assess daylight quality in built environments. One of the m...

BACKGROUND It has been suggested that year-round daylight saving would reduce road traffic injuries. METHODS and results Using 15 years of police data from north-east England, we estimate that 6.9 (95 per cent CI 1.5-12.6) fewer serious or fatal road traffic injuries to child pedestrians would have occurred in this area over this period had year-round daylight saving operated (equivalent to 0...

Designing a building with maximum utilization of daylight and use of energy efficient luminaires will reduce the cost of energy use. In the present study, by means of computer simulations using RELUX software, the interaction between natural and artificial light and the related illumination conditions expected in a commercial office building in Mumbai, India have been simulated and analysed. In...
