Samarasinghalage, T and Yang, R (2024) Evolutionary-based multi-objective optimization of BIPV envelope design: BIPV curtain wall. In: Thomson, C (ed.) Proceedings of 40th Annual ARCOM Conference, 2-4 September 2024, London South Bank University, UK.
Abstract
Multi-criteria decision-making is crucial in construction management, where diverse objectives often compete for prioritization. Optimization strategies are essential to navigate this complexity. This research optimizes Building Integrated Photovoltaic (BIPV) envelope designs at the conceptual stage, aligning with sustainability goals. Using an evolutionary-based genetic algorithm (NSGA-II), the study generates optimal BIPV curtain wall solutions considering life cycle cost and energy generation. The results highlight the significant influence of factors such as BIPV module selection, tilt angle, orientation, and application type on the energy and economic performance of BIPV facades. The ability to select optimal designs tailored to financial and energy requirements empowers stakeholders to make informed decisions early in the design process. This is particularly crucial at the conceptual stage, where decisions have far-reaching implications. The study’s outcomes serve as a valuable resource for building designers, aiding in selecting suitable BIPV façade designs during the conceptual design stage. This facilitates informed decision-making by providing stakeholders with clear insights into the implications of different choices, enabling them to select the most favorable design based on their priorities and constraints.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
