Multiobjective Design Optimization of Building Space Layout, Energy, and Daylighting Performance

Computational tools for early architectural design need to address issues related to building performance and integrally consider early design decisions regarding building form, spatial layout, orientation, and envelope articulation. This paper presents (1) a design optimization tool, Multiobjective Architectural Design Explorer (MADE) that supports performative-based building design, and (2) a design exploration strategy that effectively operationalizes MADE for Pareto-based comparative search. MADE implements genetic optimization in two steps. It first generates building layouts that satisfy formal, topological, and placement constraints with a single-objective genetic algorithm. Then, MADE determines the opening sizes of the generated layout(s) by optimizing the buildings’ energy and daylighting performance with a multiobjective genetic algorithm. MADE is tested on the design of a library building and the proposed Pareto-based exploration strategy is demonstrated in the selection of an optimal design. The results point out the feasibility of the presented tool and the design strategy, and that multiple objectives can be satisfied by sequentially optimizing design objectives.

Information Requirements for Design and Detailing of Reinforced Concrete Frames in Multiuser Environments
Anil, Engin Burak; Unal, Gokhan; Kurç, Özgür (American Society of Civil Engineers (ASCE), 2012-07-01)
The design and detailing of reinforced concrete frames is a complex process that requires intensive real-time information exchange between various design tasks. The monolithic behavior of concrete, differences in the geometric representation of structural members during the analysis and design stages, and design code requirements throughout the process add new dimensions to the problem. Additionally, especially in large projects, reinforced concrete structures are designed and detailed by several engineers ...
Optimum design of high-rise steel buildings using an evolution strategy integrated parallel algorithm
Hasançebi, Oğuzhan; Kurç, Özgür (Elsevier BV, 2011-11-01)
The present study addresses a parallel solution algorithm for optimum design of large steel space frame structures, in particular high-rise steel buildings. The algorithm implements a novel discrete evolution strategy optimization method to effectively size these systems for minimum weight according to the provisions of ASD-AISC specification and various practical aspects of design process. The multitasking environment in the algorithm rests on a master-slave model based parallelization of the optimization ...
Technological Viability Assessment of Bluetooth Low Energy Technology for Indoor Localization
Topak, Fatih; Pekeriçli, Mehmet Koray; Tanyer, Ali Murat (American Society of Civil Engineers (ASCE), 2018-09-01)
Localization in indoor built environments has considerable importance for the architecture, engineering, and construction industry. It has various use cases, including building occupancy detection, automated asset tracking in construction sites, supporting facility maintenance and operations, and guiding people in building emergency response operations. Although some initial studies examining the usability of Bluetooth Low Energy (BLE) for indoor localization exist in the literature, there is still a gap fo...
Linear static analysis of large structural models on pc clusters
Özmen, Semih; Toker, Kurç; Department of Civil Engineering (2009)
This research focuses on implementing and improving a parallel solution framework for the linear static analysis of large structural models on PC clusters. The framework consists of two separate programs where the first one is responsible from preparing data for the parallel solution that involves partitioning, workload balancing, and equation numbering. The second program is a fully parallel nite element program that utilizes substructure based solution approach with direct solvers. The first step of data...
Geographic information system-based visualization system for planning and monitoring of repetitive construction projects
Sönmez, Rifat (Canadian Science Publishing, 2008-11-01)
This study presents a visualization system based on a geographic information system (GIS) for planning and monitoring the progress of construction projects that are repetitive due to their geometrical layout. A prototype system was developed and applied to an actual pipeline project to demonstrate the advantages of the proposed approach. The primary advantage of the system is improved visualization of geographical conditions and their impact on the progress rate. Enhanced visual representation of the schedu...
