Title: Life from the ‘Earth’ in China
At the beginning of the concept of sustainable development, the trend in favor of earthen buildings is increasing in developed countries but decreasing in developing regions. In China, the earthen building is facing two major challenges, one is the frequently occurring unconventional natural disasters with another lies in the conflict between the imperfect system of rammed earth construction technology and current policy regulations, amidst ensuring the safety of housing. Innovative rammed earth construction techniques and construction engagement methods can simultaneously address the issues raised by these challenges. In this presentation, we will show our current practices to revibrate the rural community by introducing a renovated rammed earth technique and reorganize the stakeholder’s engagement of construction activities to help the in residential villagers to rebuild their confidence and power of development.

Title: Scientific Quantification of Thermal Performance of Earth Materials
The low-carbon and energy-saving properties of earthen materials have led to their resurgence in contemporary architectural practice. However, the existing research on the thermal properties of earthen materials mostly focuses on the actual observation of the thermal insulation and storage performance, and is limited by the variability of the chemical elements of the materials in different regions, as well as the differences in the composition of particle size, density, and other production elements, leading to inconsistent results and hindering the quantitative evaluation of the thermal performance of earthen materials. In this presentation, we will present our recent findings on the quantitative assessment of the thermal conductivity of earthen materials under the influence of preparation elements and the thermal storage mechanism of earthen buildings for balancing indoor temperature and humidity.
