A weighted multi-objective optimisation approach to improve based facade aperture sizes in terms of energy, thermal comfort and daylight usage

Abstract

In building design, the decision-makers should not focus only on energy efficiency as a single objective but indoor environmental quality indicators, such as thermal comfort, daylight usage and so on, should also be considered as a part of building performance. The building performance can be ensured by determining the proper performance indicators and the variables during the design. In this context, a weighted (among the objectives) multi-objective cost function was proposed, for the optimisation of energy, thermal comfort and daylight usage of a case study archetype design, through the selected design variables, considering the base architectural design principles as well. A typical social housing archetype design was determined as the case study to apply the proposed approach. The window sizes are optimised for each orientation simultaneously, for a temperate-humid climatic region. The results were evaluated in terms of improvement potentials of energy, thermal comfort and daylight performances, and the dominant values for the window sizes for each facade. According to the results, the optimised scenario achieved an 11.42% reduction in primary energy use equivalent to 181.24 kWh/m2a, a 4.52% reduction in a predicted percentage of dissatisfied with 9.12%, and a reduction in lighting energy of 4.94% equivalent to 21.17 kWh/m2a. These reductions verify the possibility to achieve higher performances on each criterion.

“…These factors are determined in the preliminary design stage (Méndez Echenagucia et al, 2015). The multi-objective optimisation method can equally consider both objectives of raising efficiency and thermal comfort while incorporating the study with different algorithms (M. Yu et al, 2015b;Delgarm, Sajadi and Delgarm, 2016b;Wang and Fukuda, 2019;Panraluk and Sreshthaputra, 2020;Acar, Kaska and Tokgoz, 2021;Ghaderian and Veysi, 2021b;Ghilardi et al, 2021;Yılmaz and Yılmaz, 2021;Y.

Multi-Objective Optimization Models to Design a Responsive Built Environment: A Synthetic Review

“…Only six publications proposed the simultaneous optimization of more than four variables. Enhancing building's energy performance levels (EN category in Figure 5) was included among the research goals of more than one hundred studies (115), whereas guaranteeing adequate thermal and visual comfort conditions (THERM and DAYL categories in Figure 5) was searched by authors of 73 and 57 journal articles, respectively (Figure 5). Finally, up to 53 studies aimed at minimizing life-cycle costs and other economical parameters (LCC category in Figure 5), whereas only 25 studies evaluated life-cycle emissions (LCA category in Figure 5).…”
