Analysis of daylight calculated using the EnergyPlus programme

Integrated automation for optimal demand management in commercial buildings considering occupant comfort

“…This is as recommended by Illuminating Engineering Society of North America (IESNA) for office buildings (DiLaura, Houser, Mistrick, & Steffy, 2000). shading devices and reflectance of interior surfaces -through the daylight factor (DF) (Carlucci et al, 2015) which is ratio of interior illuminance to exterior horizontal illuminance and the external horizontal illuminance (Ramos & Ghisi, 2010). The external illuminance is calculated in EnergyPlus through a model developed by (Perez, Ineichen, Seals, Michalsky, & Stewart, 1990).…”

Effect of internal woven roller shade and glazing on the energy and daylighting performances of an office building in the cold climate of Shillong

“…The EnergyPlus uses the split flux method to calculate the daylight at the interior after reflection from the interior surfaces [35]. Despite some inaccuracies in the daylight results calculated by the split flux method compared to Radiance/Daysim programme [36], the method can still be used in this study as a great similarity was found between the internal illuminance obtained by the two programmes with a maximum difference of 20% [37]. Also, the external illuminance in both the EnergyPlus and the Daysim/Radiance programmes is estimated using the same sky model developed by Perez et al [38].…”

Simulation and validation of a model for heating underground biogas digesters by solar energy

“…EPBSS contains many innovative simulation capabilities including time-steps of less than an hour, thermal transfer, multi-zone air flow, natural ventilation, and photovoltaic systems, amongst many others (Crawley et al, 2001;Hensen and Augenbroe, 2004;Huang et al, 2014). In addition, EPBSS has been tested using the procedures described by the International Energy Agency (Henninger et al, 2004;Ihm et al, 2004;Ramos and Ghisi, 2010). OpenStudio uses annual radiance simulation to measure daylight, and is a graphical energymodeling tool that supports whole building energy simulation using EPBSS through a combination of software tools (plug-in for SketchUp software Ver.…”
