Canadian firm MU architecture has proposed a sustainable crystalline array that is integrally linked to the city and taichung gateway park. the volumetric concept of 'taichung city cultural center' is that of a megablock divided into 13 equal bars that are stacked and rotated asymmetrically. the driving idea is to connect to the urban context by creating a gateway and 360 degree views, while allowing maximum light penetration. as the blocks peel away from one another, the exposed structure becomes a garden, reducing heat-island effect and contributing to passive cooling of the building. below the green rooves, collectors lead rain to cisterns throughout the project. the water is then used for toilets, gardens, irrigation, and maintenance. to reduce waste post-construction, the center promotes recycling and composting -- used to augment the landscaping and gardens.
Prefab lightweight steel structure and laminated lumber floor construction reduces the carbon footprint and energy consumption in project construction. the trusses encompassing each bar allow for long cantilevers, which provide shading. column-free expanses provide flexible space for exhibition in the museum and large open reading areas in the library. reducing the need for electric lighting and energy from the grid, sawtooth rooves above gallery spaces allow northern light to enter while collecting direct sunlight with southern-facing photovoltaics.
Wrapping the structure, the curtain wall panels vary in opacity, allowing or preventing passive heating and daylighting according to the solar exposure. a multi-layered light-blocking skin shrinks at 32°C to expel water. this evaporative cooling reduces the building temperature up to 15°C. the skin doubles as a solar hot water system that also provides ventilation through the center. on the ground level, a large main square with permeable paving calls taichung citizens together for cultural arts activities, recreation and special events. at the end of the piazza the elevated library spaces and extensive cantilevers form a large arch that leads to the park. with its elaborate form, and organic skin, the 'taichung cultural center' literally and morphologically bridges curves of the landscape and the hard lines of the city.
