158 DualSun hybrid panels regenerate the floor and preheat the geothermal heat pumps (and DHW) on 4 new residences – Luxembourg (LUX)

Residence Avenir has put a lot of emphasis on living comfort and sustainable development and the result is beautiful to see. It is a real energy bouquet that is set up and duplicated on the 4 buildings that make it up. A monitoring system is deployed to follow the production and consumption of energy on site.

For example, all hot water is supplied by renewable energy equipment. Thus, on each roof, around 40 DualSun hybrid solar panels regenerate the geothermal baskets and support the ERS heat recovery system.

On the hot water side, the ERS system provides for the installation of a tank of more than 300 litres that recovers grey water. At the same time, a 12 kW heat pump will draw energy from this tank. This pump will then return the energy drawn to two 500-litre hot water tanks.

In addition to this, on the heating side, on each building, the geothermal baskets regenerated by the DualSun hybrid panels will serve a heat pump. And the efforts don’t stop there, since the rainwater will be used to feed the toilets and water the garden!

“The buildings are avant-garde in their fields, highly energy efficient and technically complex, without being self-sufficient”, says Gabbana’s technical manager, Mr. Patrick de Almeida in an interview with NeoMag.

These exemplary buildings are our first large-scale experiment with geothermal coupling in Luxembourg. Other equivalent installations are being replicated in Luxembourg, for example on the Westbay real estate project.
