This study is focused on simulation-based performance assessment of a number of electric lighting system design scenarios aiming to get energy savings with increased system efficiency coupled to daylight-linked controls while preserving visual comfort conditions for indoor spaces.
This report provides a detailed analysis is conducted on the process of developing building envelope components within EnergyPlus environment with the aim of identifying required input data and the design correlates for opaque and transparent assemblies. Alternative envelope model definition methods are discussed and explained through schemas developed to reveal relationships (hierarchies) between EnergyPlus classes and objects pertaining to a specific definition method.
This report investigates developing sky radiative models for the Modelica systems programming language and compare those results to sky radiative models used in current simulation tools such as TRNSYS and Matlab. TRNSYS and Matlab softwares are commercially available, and have been used extensively to implement sky radiative algorithms linked with component-based building simulations and control implementations. While the softwares do require nancial investments to access the simulation tools,the highly modular components are adaptable to new modeling improvements that emerge in the literature.
