Social and ethical responsibility

"Masdar City has set up strict guidelines to ensure the quality of the working conditions on site. The design team has sourced locally available products for the buildings structure and envelope in order to drive down the carbon footprint and to support the local supply chain and construction economy.
The use of contemporary rammed earth walls will help to rebuild the knowledge about earthen construction techniques and to educate local workers in UAE which has a rich earthen heritage."

Ressource efficiency and environmental impact

The design strategy is adapted to the local climatic conditions and the specific requirements of Masdar City: Reduce embedded energy within the primary building construction (65% reduction in embodied carbon compared to a building with standard specification materials) - Combination of passive and active climate design strategies to reduce energy consumption (-54.9% compared with Ashrae Baseline) - Waste diverted from landfill (-60% compared with BAU) - Water Demand Reduction (-51% compared with BAU)

Economic lifecycle perfomance

The building generates a high flexibility in use and a maximized NIA/GFA-ratio (85%) to be able to provide high quality office spaces with comparable market prices. A construction grid of 9.45m, an office module of 1.35m and a depth of 14.80/16.15m allow nearly every office typology (Single, Group, Combi or Open space offices). The use of the ESTIDAMA Pearl Building Rating System (PBRS) as part of the design process secures the efficient use of materials and low lifecycle costs.

Contextual performance and impact

"The urban design draws on traditional Arabic city forms to recreate and reinterpret a variety of spatial experiences across the site plot. These spaces form a sequence of public areas, common spaces and private courtyards and creates a high level of privacy within a dense urban structure. The façade design refers to different aspects and requirements of the building:
- minimize solar radiation and maximize natural daylight
- provide direct views to the outside as well as a high level of privacy
- reinterpretate local ornamental façade design traditions
The screen is made up from terracotta tiles with a bespoke pattern of holes. The pattern will be consistent for each elevation, with the angle of holes changing subtly due to the buildings orientation. For internal elevations to the courtyards the screen will change from vertical to horizontal to facilitate communication within the building. The screen will create penumbrous effects and will provide a unique day- and night time elevation."
