-Defining+Technical+Issues

Acoustics is an inherent technical issue in my site which is situated in the middle of transportation infrastructure networks. The first step towards a successful acoustic design is zoning program components according to their need of quietness. I find "Radiant Acoustic Organization" a very effective strategy. This strategy is simply works by organizing activities from low to medium to high according to their need of quietness. I categorized program components into two main groups: short-term activities that relate to the fast transfer of people and have low need for a quite space. The activities in this group which includes commercial shops, exhibitions and farmer market will be located in a close proximity to transportation zone and work as a transitional or buffer zone between transportation systems and long-term activities such as offices and conference rooms which are, in general, need more quite spaces. The second step in acoustics design goes beyond the organization and zoning of program components to an accurate analysis of acoustics taking into account spaces volume study, the choice of finishing materials and sound insulation techniques. “The Wall” building in the Netherlands, which I am using as a technological precedent, uses a very innovative technique in sound insulation. The system consists of high quality, vacuum-formed concrete slabs supported on pressure distributor pads with adjustable tensioning elements. It uses dry, prefabricated construction techniques for fast, safe installation which is therefore unaffected by most weather conditions. This system has the capability prevents nuisance noise caused by slab movements and noise transmittance generally into the building is minimized. The building itself, the Longest Building in the Netherland, acts as an acoustic barrier between the A2 motorway near Utrecht and the surrounding suburban areas.

Another inherent technical issue is thermal design. With hot humid climate of my site passive cooling is not a major problem but passive cooling is. Passive cooling is a technical issue that needs to be studied and analysis well in the design. The thermal strategy that I will use is to divide the building skin into three layers: -Exterior Skin Assembly -Weather Barrier -Interior Skin Assembly This strategy is effectively used for The O-14 Tower, designed by Jesse Resiser and Nanoko Umemoto, which is located as it is on the Dubai Creek waterfront. The concrete exterior facade serves as an exoskeleton that provides most of the building’s structural support. The shell also prevents excess solar heat gain, and the space between the outer framing and interior funnels heat upwards like a chimney.  My design intention to integrate varied and mixed use programs creates other organizational and technical issues. The program consists of two main groups one is the generic components of transportation zones and the other is a more local program which is the farmer market. I intend by adding the farmer market as local program to create a more sense of place and cultural and contextual connectivity. The technical issue in this approach is both organizational and structural. The organizational challenge is how can these seemingly competing forces (continue) to coexist? What form can a radical new means of coexistence take? The structural challenge in this hybrid program is how to satisfy different structural need. While many of the program components need high tech structural system, the framer market needs a low tech structural system. The technical issue is how to combine these different structural systems and at the same time maintain the esthetics and visual continuity and connectivity of the project; and how to utilize these variation to create a more rich and vibrant environment instead of an odd and disconnected one.
