“…The incoming light that passes through each pinhole of the opening is then modeled using a compact radiosity formulation that allows to isolate the window as a single source contributor. In [6], a pinhole-based radiosity method was presented, but only for static sky and environment maps. The new method can deal with a whole-year dataset, providing fast http://dx.doi.org/10.1016/j.enbuild.2016.05.012 0378-7788/© 2016 Elsevier B.V. All rights reserved.…”

“…This process was proposed as an alternative to solving Eq. (1), which results in an ill-posed linear system because of the low-rank properties of the RF matrix (Fernández and Besuievsky, 2015). VNS is the method used for seeking for optimal configurations.…”

The selection and location of optimal luminaries is a central aspect of architectural design. Its complexity arises due to the diversity of existing luminaires, and the problems related to the need of achieving a set of lighting goals and constraints. The use of computer simulation software can bring an improved support in decision making at design time. CAD applications for illumination assessment are generally based on a working forward strategy, where the designer selects all the design elements, in order to calculate the resulting illumination. In this paper we present an inverse approach for the selection of luminaires, where the designer defines a set of lighting intentions to satisfy, and then an optimization algorithm iterates, converging to a feasible and optimal solution. The method allows to use a database consisting of hundreds of luminaires and a set of possible locations. In each iteration, after the first reflection of a potential configuration is calculated, the radiosity method is used to compute the final illumination of the scene.

“…Illumination‐guided design has often been addressed by very approximate or even empirical approaches in the literature (e.g. [TW13, FB15]). However, in realistic, practical scenarios, light transport in a complex environment with diverse materials can cause the distribution of incident light on object surfaces to vary significantly and is greatly affected by their relative arrangement.…”

Lighting plays a very important role in interior design. However, in the specific problem of furniture layout recommendation, illumination has been either neglected or addressed with empirical or very simplified solutions. The effectiveness of a particular layout in its expected task performance can be greatly affected by daylighting and artificial illumination in a non‐trivial manner. In this paper, we introduce a robust method for furniture layout optimization guided by illumination constraints. The method takes into account all dominant light sources, such as sun light, skylighting and fixtures, while also being able to handle movable light emitters. For this task, the method introduces multiple generic illumination constraints and physically‐based light transport estimators, operating alongside typical geometric design guidelines, in a unified manner. We demonstrate how to produce furniture arrangements that comply with important safety, comfort and efficiency illumination criteria, such as glare suppression, under complex light‐environment interactions, which are very hard to handle using empirical or simplified models.
