Discover how GE4ZERO system captures, stores, and reuses thermal energy – using solar power, underground boreholes, and intelligent real-time data management to achieve sustainable heating and cooling.
The science behind BTES
Storing Heat Beneath Our Feet
Summer
Solar and waste heat are stored underground in boreholes filled with fluid loops
Winter
The same stored heat is extracted for heating.
Efficiency
~40-50%, depending on climate and soil composition.
Storage temperatures at the end of the storing season
(approx. 15th of October)
Storage temperatures at the end of the heating season
( approx. 15th of April)
Theoretical understanding first
How the Components Work Together
Thermal response test
Determine the thermal characteristics of the ground to support accurate system design.
Defining Building Energy Requirements
Calculate how much heating and cooling the building needs throughout the year.
Analytical and Numerical Modeling
Determine the optimal size and configuration of the BTES field.
Drilling and Borehole lnstallation
Construct the underground heat storage infrastructure.
Connecting Boreholes and System lntegration
Connect the underground field with above-ground systems and monitoring components.
