Vision

The world is facing a Sustainable crisis! Now the responsibility for change has fallen to entire scientific and engineering community. We need to commit ourselves to act on it quickly. We need to turn back the environmental clock and steer the world toward a greener direction.

 

Mission

v  To help make the scientific and engineering community aware of the advantages of rammed earth construction, catalyze new international collaborations and cooperation between University researchers and rammed earth construction societies, and promote new research opportunities that can further advance our knowledge (near zero embodied energy) on rammed earth material and make it a viable building material option, leading to a greener future for planet Earth

 

Objectives

v  To help save, preserve and revitalize Hakka Villages for our common World Heritage and a more sustainable future of planet Earth

v  To emulate Hakka Tulou technologies for design, construction and operation of future green structures

v  To advance and promote use of rammed earth as a structural material and construction technique for sustainable structures

The Center for Earth Structures Project (2011-)

IHTA promotes and supports the development of a Sustainable Technology Research and Demonstration Center for Earth Structures either within or near the world heritage site of Fujian Tulou of China. The proposed center will be used as a work base not only to help save, preserve and revitalize Hakka rammed earth buildings for our common World Heritage, but also to implement Hakka sustainable technologies for design, construction and operation of green structures, and to advance and promote use of rammed earth as a viable building material option for a more sustainable future of planet Earth. It is hoped that the participants of the International Workshop on Rammed Earth Materials and Sustainable Structures, the friends of Hakka Tulou, the community of rammed earth research and construction, and any environmental conscious individuals will support and work together to make the proposed Center for Earth Structures become a reality.

Hakka Tulou and Sustainability: The Greenest Buildings in the World (2012) New!

Special Issue of Journal of Sustainability

This special issue comprises selected papers from the Hakka Tulou Forum 2011: Structures of Sustainability - International Workshop on Rammed Earth Materials and Sustainable Structures, that took place as a special session at the International Symposium on Innovation and Sustainability of Structures in Civil Engineering (ISISS2011) from October 28 to 31, 2011, Xiamen University, Xiamen, China. Rammed earth is both a construction material and technique with favorable life cycle impact on the planet Earth, yet there are challenges to implement rammed earth technologies in modern constructions. The World Heritage Hakka rammed earth buildings, i.e. Fujian Tulou of China, serve as a prime example of what rammed earth construction can offer and demonstrate how the sustainability of Hakka village architecture built hundreds of years ago and still in use today, bridge the past, present and future, with exemplary lessons for our modern world. These papers highlighting the state-of-the-art of rammed earth material and construction technologies, will surely play multifold roles in building a sustainable 21st century; including helping make the engineering community aware of the advantages of rammed earth construction and promoting new research opportunities that can further advance our knowledge on the rammed earth material for modern construction.
