Lightsolve daylight at the service of architecture
|
|
The general approach for Lightsolve is to inform well-balanced daylight design during early design stages through an interactive visualization and a pro-active, guided improvement of full- year time-varied daylighting performance. One of the underlying principles in terms of how daylighting performance is evaluated is to make it specific to the user’s own performance objectives and to his or her areas of interest, as well as to combine a synthetic perspective of full-year data with a visual impression of what the space looks like over time. |

Lightsolve is a software developed by LIPID EPFL for academic and research purposes. The application bundle is provided for free, "as is" and without warranties to students, researchers and practitioners interested in testing the tool.
Lightsolve provides likely illuminance values in reasonable time. It allows daylighting performance to be assessed by students during one exercice session, rather than a dedicated project.
The complex process of preparing an early design model for daylight simulations is made easy and the ray-tracing times are made acceptable thanks to the modern graphic acceleration hardware and libraries (OptiX) made available by NVidia.
Finally, as the OptiX based engine is not yet validated and is not yet to be used for research purposes, it is possible to switch the simulation engine to Radiance, and to intercept and modify the flux of commands and data that is sent to it.
