The integration of daylight analysis and building performance simulation together with optimisation techniques has
been a problem for simulating adaptive building envelopes. This is currently only possible by combining different
analysis tools and software as there are no conventional all-encompassing programmes available on the market. There
have been recent advances in simulating adaptive façade technologies by combining EnergyPlus simulation software
with MATLAB as well as GenOpt to perform optimisations. This work is adopting software frameworks developed
by previous researchers, applying a similar method but using Grasshopper for Rhinoceros interface. The main goal of
this study is to develop a tool that can help optimise the control of an external shading device by minimising the energy
demand for cooling and lighting (during the cooling period of the year) as well as maximising the occupants comfort
(daylight availability and room temperature). The simulation tool designed for this work integrates EnergyPlus (by
means of Grasshopper plug-in Honeybee) for building performance simulation as well as Daysim (Grasshopper plugin
based on Radiance) to undertake daylight analyses and an optimisation plug-in for Grasshopper namely Octopus
and OctopusLoop. The results of the optimized controlled external shading in comparison to static shading show
significant improvements in energy reduction and occupants comfort.
