موجز عن البحث: | In Saudi Arabia, the carbon footprint and energy use that results from using concrete in construction is a major negative contributor to the environmental effects of building materials. Likewise, the impact of annual cooling and heating energy demands has an equally prominent role to play. These demands need to be assessed and benchmarked in order that reduction targets can be set. Saudi Arabia presents its own unique context and local conditions, which creates a challenge when utilizing generic frameworks for assessing the environmental impact of domestic buildings. In meeting this aim, this paper presents a resilience and environmental sustainability assessment framework (RESAF) developed specifically for domestic buildings in Saudi Arabia. RESAF helps designers/builders to minimize the carbon footprint of the building fabric and reduce in-use energy demands of domestic buildings in Saudi Arabia. This paper shows how this framework can be used to reduce, by approximately 23%, the carbon impact from construction materials, primarily by substituting a portion of cement for pulverized fly ash (PFA) or ground granulated blast furnace slag (GGBS). A reduction of 19% in annual cooling and heating energy demand were additionally achieved throughout the building’s life, simply by increasing insulation and using triple-glazed windows. The importance of passing these alternative solutions through the resilience filter is highlighted, not least questioning whether they are really fit-for-purpose. |

عنوان المشاركة: | A Framework for Assessing the Environmentally Sustainable and Resilience Performance of Domestic Building Materials in Saudi Arabia |
ملخص المشاركة: | Studies indicate that environmentally sustainable building design and construction entails the careful assessment from cradle-to-grave of resources required in the building process. Resilience, on the other hand, emphasizes future proofing, not least mitigating long-term risks to building performance once built. Both focus on the design, building strategies and material used in construction. One of the major challenges to standardized sustainability and resilience assessment is the fact that every assessing body has its particular procedure for determining environmental sustainability and resilience, including a plethora of locally derived indicators, metrics and benchmarks. Therefore, when completely different contexts and local conditions are considered, where different environmental challenges ensue (e.g. arid regions like Saudi Arabia) they can become inefficient or simply lack meaning. The primary focus of this research is to present a framework to determine the usage of structural building materials in Saudi Arabia’s domestic buildings to minimise carbon emissions and reduce energy use. The study analyses the sustainability and resilience of various domestic properties in Saudi Arabia using locally developed and manufactured materials. The research adopts a Resilience and Sustainability Assessment Framework for Domestic buildings (RSAF) which builds upon and draws from universal procedures customized to Saudi Arabia’s needs for both sustainability and resilience. The paper concludes that structural materials are the most significant component of resilience and sustainability when it comes to carbon emissions and energy use. The framework and associated tools are expected to play a critical role in engendering greater use of environmentally sustainable, resilient building materials in Saudi Arabia. |
