Geothermal Foundation Poles

type:
zero energy building
completed:
2017

awards:
smart geotherm award 2017 - nominee

 

In our new DMOA office, we reach a zero energy consumption by combining a set of innovative technologies: concrete core activation (with passive cooling), a new generation of photovoltaic solar panels, a heath pump and a geothermal source (intubated in the 20 foundation “energy poles” under the building).
