Building Research Laboratory

This office building was built in order to prove that the space vaulted and arched built of blocks of land to better climatic conditions and conducive in the room and can be more economical than traditional buildings with flat concrete roof air.

The project was built as part of the research and development project sponsored by German agents Gate / GTZ. The building provides office and laboratory space for a research group with an area of ​​115 m2 useful.
The main hall at the center serves as a multipurpose space for seminars, meetings and exhibitions.
The third dome was built of blocks of land, utilizing slipform rotation developed by the Building Research Laboratory, University of Kassel, Germany. The resulting block of land with a manually operated press.

For heating and cooling, ground tunnel system installed. Climate conditions require a cold room from April to September and is heated from December until February. To this end, the pipeline system along the 100 m-shaped crockery installed at a depth of 3.50 m, where ambient air is blown by the two advocates. Air is blown to receive the earth's temperature is almost constant around 25 ° C, which corresponds to an annual average temperature. This building is unique as if set temperature, cooling the building in summer and warm in winter.


Energy savings result in nearly 38 000 kWh per year, about 2/3 of the total. Cost savings in the building compared to conventional buildings with flat concrete roof is 22%.
