Envelope Building Material Selection for Arid Climate with a Specific Maintainability - Design Approach: A Case Study on Governmental Office Building
Yousef Al - Hashash | Khalid Al - Gahtani
Abstract: Cladding System is a complicated problem during the architectural design processes when building is created especially under hot climate conditions. The Multi - Criteria - Decision - Making MCDM along with the Life Cycle Cost LCC Analysis and FAST had been applied to treat the research issue. This study is a benchmark for materials selection of the building envelope based on proposed criteria and designated themes in which they are collected under specific Maintainability Theme. The study had suggested ten selected materials for the building?s skin such as Metal Composite Material (MCM), Building Glass Coated, Natural Stone Panels, Wooden Panels, PVC Panels, Polyisocyanurate & Polyurethane (P&P), High Pressure Laminated (HPL) Panel, Fiber Panel and Artificial Stone Panel. The (MCDM) approach is achieved during this study, through Analytic Hierarchy Process AHP, Pairwise and VIKOR techniques. The Life Cycle Cost LCC estimation had also been engaged accordingly. After the VIKOR method, the results inclined into the Reinforced Concrete (RC) as the best among the selected ten materials. After the life cycle cost LCC evaluations, the Metal Composite Materials (MCM) or metallic came at the optimum level because of its recycling value. Delphi technique had taken a place in this research, and as Findings, the Natural Stone came first by experts? assessments. Then, the average value of the three ranking; VIKOR, LCC and Delphi had been merged to determine the best material for selection under the arid climate condition, in which the Natural Stone had appeared as the best selection, then, Artificial Stone and thirdly the Metal (MCM). On the other hand, the lowest preferences are determined for the Wood, Fiber, and PVC respectively. Finally, the results had been taken to explain the material selection issue for the Criminal Investigations Headquarter (CIH) Building in South Surra, where the cover of the selected building is Alcobond, which is one of the (MCM) category or under metallic or alloy group, in which it is presented as third preferences according to the ranking of this study. As Comprehensive results, the Natural Stone would be the optimum among the selected materials for the agent office building?s envelope in Kuwait regarding to its highest score in both Maintainability Theme and Life Cycle evaluations.
