Compressed Earth Block - Thermal Advantages

Thermal Advantages

Also, due to the enormous mass — these are monolithic walls — CEB has excellent thermal performance, reducing heating and cooling costs.

Thermal testing: From May 31 to June 3, 2004, the Biology Dept. of Southwest Texas Junior College, Del Rio, Texas, conducted tests for thermal change on three structures: concrete block, adobe and compressed earth block.

Results indicate the interior temperature of the adobe and CEB modules were significantly lower than for concrete blocks.

With a maximum ambient temperature of 107 °F (42 °C), the interior temperatures were:

Concrete Module: 111 °F (44 °C) (four degrees Fahrenheit above ambient)
Adobe Module: 95 °F (35 °C)
CEB Module: 91 °F (33 °C)

The CEB module was consistently cooler inside than the adobe by approximately 3 degrees.
