Optimization In Building Design

1076 Words 5 Pages
In the architectural, engineering and construction industry there is a growing awareness that the effective design of sustainable buildings results from an accurate optimization process of all the variables that are involved and interrelated in meeting the various sustainability goals in the field of energy, indoor environmental quality, water management, and sustainable materials [1][2].
For that reason, current frameworks for the building design process rely on a high degree of interdisciplinary collaboration between all the professionals involved (architects, engineers, consultants, etc.) from the early design stage to the delivery of the building. Such frameworks are often referred to as “integrated design process” (IDP), for example in IEA Task 23 [3], “integrated delivery

About 60% of the building optimization studies used the single objective approach, e.g. only one objective function is optimized at each optimization run (energy demand or operational cost, or thermal comfort and so on). The single most common objective was energy use, used in 60% of cases, followed by cost objectives (construction, operational, life-cycle, total). Energy and cost objective functions were present together in nearly the same amount of cases. Regarding the area of building design, building envelope occurred most frequently, in nearly 40% of works.
Typically, an integrated design process has to deal with multiple objectives. Despite the proliferation of simulation-based methods for solving multi-objective optimization problems [13]-[15], very few studies refer to methodologies for integrating the principles of the integrative design approach in building design optimization [16][17].
Moreover, there is the need of investigating how to successfully integrate building simulation and optimization tools as active design advisors in all the design stages
