According to UNEP, buildings stand for 40% of global energy consumption and contribute up to 30% of global greenhouse gas (GHG) emissions. Their report also confirmed that the building sector has the most potential for delivering significant and cost-effective GHG emission reduction.
“Countries will not meet emission reduction targets without supporting energy efficiency gains in the building sector.” – UNEP Cement is 14% of global human CO2 production.
According to the IPCC, for every tonne cement produced, one and a quarter tonnes of CO2 are released.
Considering that a majority of buildings’ GHG emissions are primarily from the use of fossil fuel during their operational phase, it is clear that there is a need to address not only the impacts of actually constructing building, but also using them. We need solutions that don’t tackle one problem at a time, but a holistic approach to our global challenges.
It is possible for rammed earth constructions to carry large loads, up to three or four stories high, but not skyscrapers. So why aren’t we saving the cement and steel for skyscrapers and using rammed earth for other housing, clinics, schools and business uses?
Apr 17, 2020 Rammed earth construction might be an ancient technique, but this house in Cunha, Brazil, is an example of how the building method can be modernized to gorgeous effect.Brazilian studio. Rammed earth is a building style that you can use to build small projects like a fire pit or bench and you can even take it a step further and construct entire buildings out of it. Let me help you with my experience to save time and a whole lot of money so you can have a beautiful finished product. Case g188d diesel engine manual.
ENVIRONMENTALLY SUSTAINABLE
Rammed earth is one of the most sustainable materials available. It has around 70% reduction in embodied energy compared to bricks, a high thermal mass, and as our modular formwork system can be removed and reused during several decades we also produce minimal waste during the construction phase. There’s further no firing process, resulting in zero kilns, zero toxic emissions and zero greenhouse gases.
HIGH THERMAL MASS
Our energy efficient rammed earth walls of minimum 30 cm thickness provides great protection from extremes in climates. The walls collect heat from the sun during daylight hours and release the warmth during the night, when the outside temperature sinks, which makes for a very slow heat/cold penetration. This allows the internal temperature to remain stable, with warmer feelings during the winter and cooler in the summer than outside temperatures. An economic and environmental advantage.

30 years of optimising our rammed earth construction process allow us to build faster than brick walling. The walls are built as a series of independent “monolith panels” made using pneumatically compacted layers of blended quarry aggregates, cement and waterproofing admixtures. We use specialised ‘Stabilform’ formwork that is stripped each following day to reveal massive, beautiful and durable walls.
LOAD BEARING
Our strong rammed earth walls are load bearing and don’t need any core filling, reinforcing or other structural framing. The massive structural panels add substantial bracing to the fabric of a building and can withstand significant point loads such as roof beams, verandah beams, floor beams and bracing beams. Rammed earth constructions around the world are still standing more than 1,000 years later, e.g. the Alhambra in Grenada in Spain and sections of the Great Wall of China.
DESIGN ASSISTANCE
We work closely with architects, designers, structural engineers and builders in order to provide the most current advice available to help achieve ideal rammed earth construction outcomes. Our assistance is free and covers structural design, projects scheduling and cost estimates for both residential and commercial buildings.
