Accessory Dwelling Unit

Fall 2017 | Regenerative Architecture | UTSOA | Prof. Garrison

Project Partner: Carol Fraser

The research on how architecture has been adapted to a variety of climates throughout the world in a way that reduces or eliminates the need for mechanical or active heating and cooling systems while ensuring maximum human thermal comfort was done. With that knowledge, combined with an understanding of the climate of Austin, Texas, to design an accessory dwelling unit (ADU) on a lot of a single family home in East Austin. The design takes into consideration lessons learned about building in climates like Austin’s, especially aspects of site design, building orientation, configuration, envelope, and shading.

Concept Development and Strategies learned from research 

Building Configuration

  • One storied rectangular building

  • Open living, kitchen and dining in north side and bedroom and bathroom on south side

  • Building is raised above the ground

  • High ceiling height is provided

  • Architecture elements like verandas and projecting roofs are provided for shading

​

 

Building Envelope

 

Wall Design

  • Double wall with a cavity

  • Inclined east and west wall which act as a vertical shading device

  • Lightweight and high thermal resistance building material

 

 

Roof Design

  • Two-way slope roof

  • The double ceiling in between creating a clerestory window for living and bedroom through which hot air is ventilated.

 

 

Fenestration Design

  • Large openable windows

  • In both windward and leeward direction for cross ventilation

  • Shading is provided in each window
