estidamah center | i8 At the south-west elevation, light shelves protect the internal spaces from direct sunlight and reflect more natural daylight. The solid parts of the exterior façade are clad with mechanically-fixed local limestone and have punched modular window openings. As visitors walk through the main entrance, they are welcomed by the open office spaces around them. Natural light infiltrates the dynamic sky-lit atrium, which provides 50% of the building’s light source. The open office spaces allow for maximum daylight to enter, creating a simpler, more intuitive circulation strategy. The enveloping storefront glazing gives the building’s occupants a visual connection to the outdoors. These storefronts will include operable windows, providing natural ventilation during moderate seasons. The design also incorporated water-efficient landscaping. Native and adopted species are arrayed throughout Estidamah Center, requiring minimal maintenance and watering. Xeriscaping was applied to most of the outdoor areas alongside gravel hardscape. Water-efficient fixtures and fittings were selected to reduce the use of potable water by 30% from the conventional water baseline, and consumption meters were provided to measure, verify and assess performance. Last but not least, more than 10% of the total materials used were regional materials, and more than 20% were recycled. Thanks to these measures, this modern and unique project will hopefully stand as a symbol of sustainability in Riyadh for many years to come.
