Underground Thermal Energy and Storage (UTES)

Underground Thermal Energy and Storage (UTES)

Reducing and recycling the use of sustainable energy is a hot topic worldwide. To improve and increase the contribution of sustainable energy the use of soil energy is promoted. The advantage of the underground is that large amounts of energy can be buffered either by open systems for heat exchange (in which water is pumped in and out the underground) or by closed systems (pvc tubes in which water flows). In warm periods excess heat of buildings, other constructions, industrial processes or from the air can be stored   in the soil and in cold periods it is used for heating. Energy neutral buildings can be constructed as the low underground temperature at the beginning of the summer is used for cooling purposes.

 

In Romania there are lucrative opportunities to implement a new technique to manage the temperatures in buildings. The current heating system in Bucharest has a low energy efficiency resulting in high energy costs and high environmental impacts. Romania’s land climate implies high temperature differences during the year. These conditions and the characteristics of the soil and the sun are the strengths of our design. The combination of energy storage in the ground and solar energy has a high potential to realize ‘energy zero’ buildings in Bucharest.
