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

v Thesis
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.

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 (ISISS’2011) 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.
