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 .

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.

CIBSE recommended lux/ lighting levels for office spaces

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.”

Dang Wangi

With a focus on historic city centres, we were first established in 2009 by Khazanah Nasional Berhad - the investment arm of the Malaysian government. Through the George Town Grants Programme, we were able to demonstrate the benefits of a community-focused, collaborative approach to the regeneration of cities. Our success in Penang grew existing relationships with local and national institutions while opening up further opportunities to widen our partnerships locally and internationally. Today, working closely with local authorities, communities, institutions, private entities, and global experts, we continue to trial, plan, and implement programmes to rejuvenate cities. Supported by a strong network of local and international partners that are equally committed to the creation of better cities for all. To fulfil our mission of rejuvenating cities, we support community-driven initiatives through the public grants programme alongside implementing our own management initiatives in partnership with local and international partners. These initiatives typically fall into one of five themes: Space Activation, Public Realm Improvements, Content and Culture Curation, Capacity Building and Research & Advocacy.

HYBRID DOUBLE SKIN FACADE SYSTEM Proposal for thinkHUB building

Many types of DSFs have been developed since the first double layer was used in the building envelope (Wigginton, 2004). However, LeCorbusier’s Mur Neutralisant shown in above figure, 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.

Therefore, it is helpful to agree on a consolidated classification of DSFs (Parkin, 2004). As in above figure, an overview of the main characteristics often used when describing the various features of DSFs

Consist of inner and outer layer of envelope or skin, usually made from glass material and set apart around 200mm to 2000mm (depending on the design and performance intended) that forms a cavity which allows air to flow through. In this gap convection occurs. The cavity traps air which then absorbs solar thermal energy and diffuse radiation and direct sunlight.

Fundamentally, solar radiation passes through the outer glazing of the façade and heats the air inside the cavity. Stack effect occurs as cool air travels vertically within the cavity thus venting out the hot air and at the same time reduces the cooling load of the building. Shading devices and strategy can be applied at the DSF system to further reduce solar heat gain. Barbosa, Ip and Southall (2015) identified three key parameters that have significant impact on performance for DSF which are, façade design (tectonics), building design and site conditions. Glazed facades have large impact on the impression of a building, it affects indoor climate and energy aspects of the adjacent buildings and has some aspects, which more or less interact or depend of each other. These aspects are shown in figure 2.2.5. Besides these aspects of architecture, indoor climate and energy some basic functions of facades should also be fulfilled for double skin facades without depreciation compared to a traditional facade. The basic function of a facade is to serve as a building envelope, keeping out cold and water and letting in air and light. The double skin facade serves as an extra buffer zone and collector of solar energy or as a shaded ventilated cavity protected from rain and strong wind (Tombazis, 1996). DSF concept can also be used to meet lighting problems of in-sufficient daylight or extra glare of daylight for buildings. Though, most research on the DSF carried out are concern towards ventilation and thermal performance. This study will focus on daylighting performance of DSF for office building. Double Skin Façade can exclude most direct sunlight and introduce reflected light, to control entering daylight and heat gain. Access of continuous homogeneous daylight is important for working spaces and for two reasons, to avoid excessive darkness as well as to avoid excessive glare caused by excessive entry of daylight at certain times of the day to face their negative impacts, with reducing consumed energy to achieve required lighting level (Napier, 2015).
