Following a detailed analysis unique requirements that are associated with CFS, comparative study capabilities different software implementations is presented. In addition, we present on state-of-the-art approaches to obtain necessary Bi-directional Scattering Distribution Functions (BSDF), involving experimental characterisation, databases,...

Extensive literature exists on the use of dynamic shading devices for control visual and thermal comfort in non-residential buildings, however research residential sector is far less widespread. Several strategies thresholds are utilised literature, yet it unclear how these should be chosen. The aim this work to evaluate impact several parameters three Key Performance Indicators (KPIs) (adaptive overheating, useful daylight illuminance heating demand) a case-study apartment near Bologna,...

This study evaluates the calculation approach of energy requirements for artificial lighting inside buildings different use according to EN15193-1:2017, defining main scope standard, highlighting its limitations, and proposing improvements. The evaluation was carried out through a parametric analysis determine influence window-to-wall ratio, distribution windows, presence side opening, glazing visible transmittance, overhang length on Lighting Energy Numeric Indicator (LENI) living room an...

Complex Fenestration Systems with integrated shading systems are becoming widely used to enhance the building's envelope performance and increase occupants' thermal visual comfort. Their peculiarity of integrating a complex system makes it difficult assess their optical performance. The complexity itself, in addition interaction fluid flow window cavity, calls for use adequate modelling simulation techniques. In this framework, novel approach characterization venetian blinds at different...
