DAYSIM allows users to model dynamic facades systems ranging from standard venetian blinds to state-of-the-art light redirecting elements, switchable glazings and combinations thereof.
In addition, by developing system geometry to redirect daylight to specific zones within the space, optical light redirecting systems have the potential to avoid the glare conditions commonly produced by conventional facade shading systems that direct significant amounts of daylight below head height into the occupant's field of view.
When Bjorn Helgason's meticulous lighting redirects our attention, we realize something is askew in the room upstairs, which is turned on its side, giving us an overhead view.
This paper investigates the concept and quantifies the impact of combinations of solar protection and light redirecting devices.
For inner region of deep plan offices, some innovative daylighting systems such as light redirecting panels and light pipe could be used to improve the daylighting performance.
The design workflow including the mathematical model and the optimization tool proved to be a cheap and reliable solution for an initial design of light redirecting panels.
A method was also proposed for evaluating daylight distribution in rooms of ancient buildings with small transparent surfaces and high thermal inertia, using solar shadings and light redirecting devices.
The laser light was redirected, or diffracted, at a particular angle by the rows of atoms—just as x-rays diffract off the ions in a real crystal.
In addition, not all of the light is redirected; some of it gets absorbed or scattered, creating small reflections and shadows that give away its presence.
Subsequently we use these transfer functions to calculate the free surfaces of the TIR collimator such that the light is redirected according to the relation defined by the transfer functions.
This solution should also reduce photodamage considering that most of the excitation light is redirected outside of the cell body.
