SkyVision 1.2

SkyVision is an easy-to-use, Microsoft WindowsTM-based computer program developed by the National Research Council Canada in partnership with Natural Resources Canada and Public Works and Government Services Canada. The software calculates for a given design day, the overall optical characteristics (transmittance, absorptance, reflectance and Solar Heat Gain Coefficient) of various skylight types, performance indicators of skylight/room interfaces (well efficiency and coefficient of utilization), indoor daylight availability (daylight factor and illuminance) and lighting energy savings. It is intended for use by skylight and curb manufacturers, building designers, architects, engineers, fenestration councils, and research institutions.
Features:
* Detailed calculation of skylight optical characteristics and indoor illuminance
* State-of-the-art glazing optics calculation models.
* Ray-tracing-based modelling to compute the skylight optical and daylighting performance.
* Side-by-side comparison of design performance.
* Results in graphical or tabular formats that can be used as inputs for third-party software such as building thermal simulation software.
* Choice of two unit systems: English (IP), or International (SI).
* Attached glass product database to build skylight products.
* Climate file database to simulate scenarios with real, dynamic sky conditions.
* On-line help.
* Automatic lighting and shading control effects.
