As part of sustainable architecture principles and practices, designers need to define building's architectural requirements based on climatic conditions, environmental preservation and reduction in energy consumption. The natural energy sources such as solar radiation affect thermal and lighting performances of buildings depending on its facade characteristics. Traditionally, buildings thermal...

CODYRUN is a multi-zone software integrating thermal building simulation, airflow, and pollutant transfer. A first question thus arose as to the integration of indoor lighting conditions into the simulation, leading to a new model calculating natural and artificial lighting. The results of this new daylighting module were then compared with results of other simulation codes and experimental cas...

The rendering software supports direct point lighting and also environment lighting. We approximate environment lighting based on captured lighting environments. We use an image-based environment illumination technique to light the face with a specified environment map. An example is shown in Figure 1.The environment map is prefiltered with several blur kernels, for diffuse integration, glossy ...

A new integration method is presented to recognize the emotional expressions of human. We attempt to use both voices and facial expressions. For voices, we use such prosodic parameters as pitch signals, energy, and their derivatives, which are trained by Hidden Markov Model (HMM) for recognition. For facial expressions, we use feature parameters from thermal images in addition to visible images...

The aim of this paper is to briefly recall heat transfer modes and explain their integration within a software dedicated to building simulation (CODYRUN). Detailed elements of the validation of this software are presented and two applications are finally discussed. One concerns the modeling of a flat plate air collector and the second focuses on the modeling of Trombe solar walls. In each case,...

The coupled magneto-thermal problem is analyzed, with reference to a particular heating application, by means of an equivalent thermal network, that is based on a first-approximation interpretation of the field equations. The connections between the thermal characteristics and the magnetic ones are taking into account by considering the skin-effect and the dependence of electric conductibility ...

The proper application of a shadow model during the integration of orbit trajectories requires that the solar radiation pressure be sampled adequately during transitions between lighting conditions. An integration scheme is presented in which the lighting condition is held constant across steps of a primary integrator. If the lighting condition changes during that step, then an Encke-like integ...

Lighting plays a key role in night escapes of urban spaces, in a way that it can be effective in giving identity to them. By considering this importance and inexistence of a process for composing urban Lighting strategy made this study to be conducted by the objective of providing process for compilation of context-oriented lighting strategy in urban spaces. Reaching a suitable solution for Li...
