Tectonics for Facades in Tropical Climate
Sustainable architecture is architecture that seeks to minimize the negative environmental impact of buildings by efficiency and moderation in the use of materials, energy, and development space and the ecosystem at large.
IIn the beginning, to exploring Facade Tectonics, Double Skin Facade properties is explored. Tropical Climate in relation to DSF then understood. Findings then decide the Tectonic for Facades in Tropical Climate. Figur below showing some example of DSF .
PRETHESIS FRAMEWORK
Keywords ; double skin facade, tectonic, tropical climate, daylight level, building placement. AIM ; To identify thus develop a facade system which is suitable for the tropical environment (Malaysia) for an office/institutional building in Kuala Lumpur urban context. OBJECTIVES ; To identify technology and tectonics of double skin facade system which suit the tropical environment and translate in facade design of porposed building // To understand various facade application, performance and construction or tectonic in adapting its design onto tropical climate focusing on DSF primarily // To validate a design of facade for and office/institutional building in Kuala Lumpur urban context in terms of daylight level and building placement.

The modern workplace is undergoing a paradigm shift of changes in usage patterns and longevity of working hours. We as architects and interior designers need to design space such that the users are more comfortably integrated with their physical surroundings at the workplace. A big contributing factor towards indoor comfort, are the lighting levels. Le Corbusier identified the significance of light in architecture best when he articulated the viewpoint, “Architecture is the masterly, correct and magnificent play of volumes brought together in light.” Area Offices General Computer Stations Filing Rooms Print Rooms

Le Corbusier’s Mur Neutralisant was an early experiment with a type of double skin façade system. It proposed the use of blowers to circulate heated air between two layers of glazing. It was not constructed as proposed, instead installed as sealed glazing that failed miserably. The entire façade was redesigned with operable windows. the Cite de Refuge image show current façade condition.

Low Wall to Window Ratio: This strategy can be successfully in the workplace typology by understanding the internal working patterns of an office space, given the requirements of work desks in the space all the sill levels can be successfully be maintained at 1100mm, this reduces the façade area that need to be glazed and also helps in achieving a lower wall to window ratio. According to the Beijing University of Civil Engineering and Architecture, studies have proved that by increasing the sill height by 0.1m an increased lighting saving of 0.219 W/m2 on sunny day as well as 0.225 W/m2 in cloudy day is achieved. To further optimise on this strategy minimum openings are planned on the east and west sides of the building. Orientation and Building Form also influence Sustainable Technology application. To optimise on daylight, the building must be oriented for solar design; this ensures that the proposed building can optimise and make the most of passive and active solar strategies.

One important methods of saving energy in a building is by carefully designing its facade. A ‘double skin facade’ is optimally one of the best options in managing the interaction between the outdoors and the internal spaces. It has the ability to efficiently reduce energy and therefore saves cost. The amount of energy saved depends on the climate and the design chosen. The design of the DSF involves decisions on geometric parameters, glass selection, ventilation strategy, shading, daylighting, aesthetics, wind loads, and maintenance and cleaning cost expectations. DSF has an impact on several aspects of the design phase of a building. For example, thermal properties, acoustic characteristics and daylighting are affected in the exploitation phase of the building. In addition, in terms of building safety point of view, fire propagation maintenance or glazing thermal break must be taken into account.
Various tectonic configuration designed for DSF depending on intended building performance and use. Tectonics in architecture is defined as “the science or art of construction, both in relation to use and artistic design.” It refers not just to the “activity of making the materially requisite construction that answers certain needs, but rather to the activity that raises this construction to an art form.”
