Abstract
This paper presents a comparative study among simulation tools in their capabilities of evaluating complex fenestration systems in terms of their thermal and daylight performance. Two powerful and flexible toolchain approaches based on EnergyPlus and TRNSYS including third-party tools are analysed in detail and their procedure in model setup are shown. By investing into comparative simulations, capabilities of both toolchains are highlighted and proand cons are discussed within this paper. By comparison against measured data, the ability of both toolchains to predict real case scenarios is shown. Satisfying alignment has been achieved for both tools in energy performance prediction (cooling loads, temperatures) as well as daylighting predictions (illuminance levels). Remaining deviations show the sensibility in used model definitions, used data as well as tool handling.
