 +====== Overview ======
 +**Validation of illuminance predictions from lighting simulation programs**
 +  * The BRE-IDMP validation dataset was used to test Radiance predictions.
 +  * Comparison of predictions with measurements in full size offices under real sky conditions.
 +  * Measured sky luminance patterns were used in the simulations.
 +  * Radiance predictions proved to be capable of high accuracy (+-10%).
 +  * The most rigorous validation of illuminance predictions under daylight conditions to date. 
 +  * Investigation of confounding factors present in validation studies.
 +  * Parallax errors in sky simulator domes proved to be fundamental limiting factor for high accuracy work with scale models.
 +**Daylight coefficients**
 +  * Formulation of a refined daylight coefficient approach using standard Radiance. ​
 +  * Efficient computation of time-varying daylight illuminances based on hourly meteorological data.
 +  * The daylight coefficient solution invariant to building orientation and locale - rapidly evaluate design scenarios for multiple orientations and climate locales.
 +**Useful daylight illuminance**
 +  * A climate-based daylighting metric.
 +**Illuminance Proxy - High Dynamic Range Imaging**
 +  * A HDR method to measure arbitrarily complex illumination fields under real-world conditions.
 +**Spatio-temporal mapping of solar penetration in buildings**
 +  * Fast, image-based approach to generate spatial and temporal maps of direct solar irradiation in buildings.
 +  * Precise, rapid evaluation of parametrically generated complex roof systems.
 +**Irradiation mapping and solar access in dense urban environments**
 +  * Total annual irradiation is a measure of all the energy from the sun and sky that is incident on a surface over a period of a full year. It is a more realistic measure of solar access than those based on idealised conditions, e.g. CIE overcast sky.
 +  * Image-based approach to predict total annual irradiation in complex urban environments (ICUE).
 +  * Building applications include BIPV and solar-microclimate responsive facade design.
 +  * General applications include evaluation of solar access for buildings and open, public spaces.
 +**Driver exposure to particulates**
 +  * In-car measurements of coarse and ultrafine particulates to determine driver exposure.
