Approach to Performance-orientated Design Bridge Typology - Dictates performance parameters to be analysed - Lateral loading isn t as much an issue for bridge de sign as it is for high rise - However others become more important - Solar exposure vs Wind mitigation - Addition of urban space within bridge to be taken into account - Additional need for bridge structure amongst building structure
Key Criteria to address - Investigate how Performance-orientated Design can be used to increase urban design quality -To enable a greater quality of life whilst living in the context of a bridge - Discover new ways of optimising built form to suit environmental and structural performance criteria - Combining the first two criteria to create a final synergetic response to the brief - Enable a way to link design with surrounding river context
Integrating Performance and Parametric Design Tools for Urban Daylight Enhancement Precedent Studies The majority of the natural lighting, in urban slums and rural areas arround the world, is blocked off and virtually no light reaches the building spaces in lower floors as well as the streets and urban spaces. Painting the buildings surfaces may increase the availability of daylight below. Some surfaces may be easier to paint and will require less cost or effort to paint than others. This paper formulates a combinatorial optimization problem to address this situation and uses different approaches to solve the problem. The problem is solved using different optimization algorithms namely; genetic algorithms, partical swarm optimization, generalized pattern search and a hybrid approach. A comparison between the different approaches is given and recommendations on future research are made.
Precedent Studies Melbourne Central Melbourne, Australia ARM Commercial development interlinked with the busiest commuter rail station in Melbourne. Aim for the project was to imporve the relationship between the retail/commercial components and the existing rail station. ARM set out to integrate the two to create a new urban hub. This was achieved through circulation analyses and by studying how people interact with the existing space which lead to the creation of a matrix of city laneways to improve circulation. The addition of logical pedestrian routes combined with smaller alley-like penetrations into the space. Shifting the character of Melbourne Central from an insular retail terminal to a zone which is both a destination and a transit space.
Iseldoks Doetinchem, Netherlands Precedent Studies De Urbanisten Masterplan project involving the transformation of a disused industrial precinct into a new urban precinct along the river Oude Ijssel. Project is to take form over the next decade or so and will comprise of the creation of over 400 dwellings, shops and urban facilities. Like many rivers in the Netherlnds, the Oude Ijssel is prone to flooding so the design has to find a way of incorporating this constraint into the proposed urban plan. De Urbanisten understood the long tradition that the Dutch have of living around water and the potential for it to contribute to an increased quality of life and used this as a driving factor in their design. A new canal was created with houses situated along the quay and directly in the water along with a harbour to create a central urban space. Stormwater collection has been integrated into the design to positively affect residents through using the retention and discharge process as a key visual identity for the area. This was achieved through the creation of rain gardens open gutters and water squares that gradually lead into the canal. Certain areas within the quays have been made lower than usual intentionally to encourage flooding at times. De Urbanisten made this design decision to bring people closer to the water to have a positive effect on urban life within the Iseldoks.
Water Squares Doetinchem, Netherlands Precedent Studies De Urbanisten This project set out to combine water storage with the overall aim of improving the quality of urban public space. De Urbanisten seeked to draw more value out of money invested in water storage facilities by making them visable and enjoyable to the public. They also used it as an opportunity to create environmental quality and give identity to central spaces within residential urban precincts. The water square is designed in two parts: an area for sports and a playground situated on a hill. Most of the time these areas wil be dry but in instances of medium-heavy rain, portions of the site will start to fill up, actively reshaping the environment and changing the activities that are associated with it. There have also been water treatment strategies designed into some of the slopes which lead to its use being made part of urban design policy within Rotterdam.
