passive cooling

Following the research on Dubai’s climate and optimal massing configuration for structures in such hot and humid climates, further experimentations using clay on a 1:200 model were made in order to explore the massing and porosity of the structure and how to maintain a cool environment on the interior of a building with such a large footprint area. Along the linear formation of the structure a series of wind tower shafts will be placed in a row in order

FACADE STUDY

timber louvers

passive cooling

In order to reduce noise from the motorway and provide shade on the south east facade, a timber louver screen will form the external skin. Louvers will be fixed on a metal array system . The timber louvers are attached onto a metal array system. Using metal plates the whole skin will be fixed directly onto the concrete slab on each floor. – 28 –

One of the traditional and most efficient ways to cool a space in Dubai’s history was the wind tower. Tall traditional structures formed the skyline of anciet Bastakia, one of Dubai’s oldest areas (fig.1). These 5 structures(fig. 2), open on one end, creating 5 long shafts/cores (fig.3) into the building, allow air to enter while other opposite vents suck it out (fig. 4) creating a vacuum phenomenon. Underneath each windtower there is a water feature which aid in cooling the space faster while at the same time regulates the amoubt of humidity in the environment. – 32 –

WATER SCREEN In order to tackle water scarcity in the area, water will be sourced from the creek filtered and pumped into the building forming pools uderneath the wid towers. The final water feature will be a water screen; a wall wit running water where student’s work can be projected and exhibited to the general public.

MSA MArch 2013 TERRACOTA FACADE

The outer skin of the north west facade is formed by a terracota tiles facade with volumesshifting on the horizotal axis creating an uneven facade with volumetric differences. The concept behind it emerges from the ancient city of Bastakia in Dubai. Tall buildings and narrow streets formed the city’s morphology thus creating a microclimate in between them. The same principle was applied to this facade on a vertical axis.

CONSTRUCTION AND SUSTAINABILITY ISSUES General

the sun. (fig. a)

Buildings contribute considerably to global warming and ecological problems, thus, humanity is nowadays poised on a threshold where systematic ecological design will promote a paradigm shift in the concept of development.

Kyosemi Corporation has unveiled tiny spherical solar cells that can be used to create energy harvesting windows in the not-so-distant future. The Sphelar solar cells are solidified drops of silicon measuring 1.8mm in diameter and are highly transparent.

Rethinking the ecology of building and landscape use and the instrumental competence of materials, construction and environmental systems in an increasingly urban world is a critical aspect not only of my unit’s agenda but also of my final year project. The suggested building proposal addresses this problem using renewable energy. Solar cell glazing will be used to all windows facing

The cells can be embedded in glass to create a transparent solar cell window, which can capture sunlight from any direction or angle. These windows would also be highly efficient, since both sides of the glass can collect and convert sunlight into electricity. Passive cooling ventilation systems(fig. b) are essential in a hot and humid climate such as Dubai.

Skin For this particular building research refered back to the traditional vernacular architecture in Dubai where they used wind towers to capture wind current and channel it through a shaft in order to cool down buildings. (fig. b) Timber loovers were also used to provie cooling (TECH D) Locally sourced materials such as earth, sand and pine trees timber are used to form rammed earth walls, concrete used for structure and timber louvers thus minimising transport cost and pollution. Water harvesting from the river adjacent to the site will be collected, filtered and recycled to be used as grey water (fig. c+d).

Analysis:

As illustrated in the axo in fig. e, the skin of the proposal is formed by rammed earth walls at the groundfloor level (fig. f), a screen of timber louvers from the south west elevation from the first to the top floor (fig. f) and 5 diferent concrete slabs with timber wall wind towers embeded on them form the roof of the structure (fig. g).

ENVIRONMENT- ENERGY STRATEGY The environmental strategies start with form and orientation and move on through fenestration and integration. In Dubai the climate is hot and humid through out the year (fig. a)therefore no heating provisions were taken into consideration.

(fig. a)

However, initial calculations using Autodesk Ecotect and Vasari (fig.b) showed that the selected site is optimally oriented on the SW-NE Axis. If the side towards North East is higher then a ‘buffer’ area is created. As mentioned before, in order to create and maintain a cool environment in such a climate passive ventilation and other sustainable methods of maintaining a building’s thermal mass will be taken into account.

SUSTAINABILITY CONSIDERATIONS Most of the chosen materials for this proposal are locally sourced in order to minimise transportation emissions. The ground floor of the building consists of Rammed earth walls, while sand and water is sourced locally to form cement and thus, concrete used for the main structure. Terracotta tiles cladding on one facade of the building also make use of local sand. Furthermore, timber louver screens will be placed on the south east-west side facing the motorway since it is the facade which is most exposed to the sun. For passive ventilation wind tower structures will be used.
