Main Title: Design optimization method for roof-integrated TSSCs

Abstract: This paper proposes a two-step design optimization method for roof-integrated two-stage solar concentrators (TSSCs) as energy supply systems. The integration process of these systems with buildings is complex as several conflicting and multi-disciplinary concerns need to be addressed. Thus, the proposed approach is intended to be adaptable to informed decision-making processes in early design stages, and yet to be collaborative where several key stakeholders are involved. The method is an extension to our previously developed approach where the performance of roof-integrated TSSCs in several design scenarios is accessed along with multiple performance indicators by developing a parametric model and controlling a set of design inputs. In the current study, the proposed method is combined with a multi-objective design optimization method, aiming to optimize, building and TSSCs geometry. The method was validated in an illustrative case study of a single-family house (California) for a number of conflicting objectives e.g., maximization of direct normal solar irradiance (DNI) and annual average load match index (av.LMI), and minimization of covered roof area. The validation of the method shows a number of interesting results. The method enables the generation of performance-driven designs and searches for the most appropriate solutions, that can help to meaningfully support the decision-making process.
