The renewed attention paid to raw earth construction in recent decades is linked to its undoubted sustainability, cost-effectiveness, and low embodied energy. In Italy, the use of raw earth as a construction material is limited by the lack of a technical reference standard and is penalised by the current energy legislation for its massive behaviour. Research experiences, especially transoceanic, on highly performative contemporary buildings made with natural materials show that raw earth can be used, together with different types of reinforcements, to create safe, earthquake-resistant, and thermally efficient buildings. On the basis of experimental data of an innovative fibre-reinforced rammed earth material, energy analyses are developed on a rammed earth building designed for a Mediterranean climate. The paper focuses on the influences that different design solutions, inspired by traditional bioclimatic strategies, and various optimised wall constructions have in the improvement of the energy performance of the abovementioned building. These considerations are furthermore compared with different design criteria aiming at minimising embodied carbon in base material choice, costs, and discomfort hours. Results have shown the effectiveness of using the combination of massive rammed earth walls, night cross ventilation, and overhangs for the reduction of energy demand for space cooling and the improvement of wellbeing. Finally, the parametric analysis of thermal insulation has highlighted the economic, environmental, and thermophysical optimal solutions for the rammed earth envelope.

Raw Earth

In a world context focused on energy efficiency and sustainable construction, returning to the use of raw earth in construction constitutes a good alternative to concrete construction, a system more energy consuming and yet more used nowadays. This return is justified by the excellent energy performance and the high level of thermal comfort provided by earth constructions in different climates. In cold climates, adding an insulation on earth walls has proven to be effective in improving their thermal performances. However, the influence of adding an insulation on the energy performance of rammed earth buildings in hot and arid climates remains to this day little explored. The present work comes in this order of ideas; it is based on a comparative study of the energetic performances of a mud building before and after the addition of the insulation. In order to compare between their performances, we have performed a simulation of the thermal behaviour of each by the dynamic thermal simulation software Design Builder.

Field tests for indoor thermal environment of Tibetan-style dwellings of different materials in Shangri-La in winter were carried out from the perspective of physical environment of buildings, and more specifically, the indoor temperature of Tibetan-style dwellings with rammed earth walls and brick walls as well as the surface temperature of building envelope were tested and comparatively analyzed. The test results show the current situations and features of indoor temperature changes of Tibetan-style dwellings of different materials, which may provide a basis for improving the thermal environment of Tibetan-style dwellings.

Poor Lighting

When we are busy discussing how we should improve the bad physical qualities of traditional cave houses, such as humidity, poor lighting and ventilation condition, we fail to notice that a unique earth dwelling, adobe cave house, has long existed in the Longdong region of Gansu province. The type of earth dwelling is facilitated by traditional building technique such as rammed earth walls and adobe vaults, which does not only fixed the defect of humidity, bad lighting and ventilation condition, but it is also a typical green ecological building. The article takes the adobe cave house as the object of study, starting from the relation between resources and buildings, deeply probe into the underlying building wisdom. Aiming at the main existing problems, the article is dedicated to exploring new model of building vernacular earth building, with the intention to alleviate the contradiction between man, resources, environment and buildings. And after all, to provide theoretical foundation and practical guidance for building the new vernacular earth dwellings.
