The Vertical Zoo: A wild greenery-wrapped tower that provides refuge for animalia

We've seen tons of <a href="http://inhabitat.com/tag/vertical-farm">vertical farms</a>, but what about vertical zoos? Why not take the same theories and technologies used to grow organic produce and raise animals and apply them to build more compact, more <a href="http://inhabitat.com/tag/eco-zoo">sustainable zoos</a>? Proposed by Mexico City-based <a href="http://www.bubarq.com/home.html" target="_blank">BuBa Arquitectos</a>, the Vertical Zoo is a balanced and sustainable space where people and animals can coexist in harmony. Wrapped in lush vegetation, the star-shaped building makes use of green building strategies to reduce heat gain, encourage natural ventilation and soak up rainwater. Totally self-sufficient, the tower's aim is to be a sustainable refuge for all animal kingdom species.

The zoo's is built from a six armed star-shaped level, designed to maximize space, views and circulation.

It is based on a nucleus or a tree trunk from which emerges six branches, each 20 sq meters in size and serve different programmatic needs.

These program blocks provide space for zoo activities, visitor needs, administration, circulation and ventilation and spaces for sustainability.

<a href="http://inhabitat.com/tag/modular-housing">Modular</a> by design, more star-shaped levels can be added on top as needed or as funding becomes available for new facilities.

Lush foliage surrounds and projects the tower and its inhabitants from the elements and creates an overall picture of harmony.

Totally <a href="http://inhabitat.com/tag/net-zero">self-sufficient</a>, the vertical zoo is capable of providing its own water and energy through rainwater collection and <a href="http://inhabitat.com/category/solar-power">solar power</a>.

Arrangement of the star-shaped levels encourages natural ventilation and improves views. Multiple towers can be built together to create a larger interconnected complex.

The Vertical Zoo is designed to be as much about the animals as it is about the people who visits and encourages meeting and cohabitation as a way to promote equanimity between the species.

Although <a href="http://inhabitat.com/tag/zoo">zoos</a> are not always the most humane place for animals, there may come a time when we need to protect species from total extinction. This vertical zoo attempts to find a sustainable solution.
