Daylight performance simulations 02

As a respond to prior daylight simulations, the aperture of the local system is altered as well as series of global formations, changing conditions upon how light falls into the building. This has enlarged the atrium space to the east, kept a height to depth ratio of app. 1:2 with improved factors as result. Three simulations with diverse panel organisation is done to recognise light levels and light effects. 01) symmetrical pattern in chess board organisation 02) with slightly more opaque than transparent panels and 03) with irregular pattern organisation, but in relation to internal programme. All three simulations reveal daylight factors from 2% in the darkest areas to 60% near the envelope. The colour charts look simular (as with daylight performance simulation 01), but have slight differences, with panel organisation 03 as the best with the idea of controlling light levels in different zones of the building. The organisation of panels will be done in a more precise iteration of spatial aspects with thought to phenomenological perspectives of light and shade.  

Local system III [cumulative radiation/thermal mass 02]

Alteration of the parametric input controlling aperture throughout the envelope has created improved internal absorption of energy. This is done in relation with changes in the internal organisation. The pure yellow indication on the right illustration (summer period) is misinformation to the reader as the open air cafe is located here, exposing the thermal mass to the outside, with little effect to internal temperature changes. Colour schemes/designs and material application will follow the information derived from the simulation/analysis, which will be illustrated in forthcoming spatial illustrations.
