Solar cooling

HelioPower JouleWall

HelioPower core technology is building surface integrated heat exchangers. Which during the day harvest energy for heating purposes. Next step is during the night time to lose energy to the universe for cooling purposes. All within the same systems!

Combine the HelioPower technology and the JouleWall technology - the future integration of various building parts into an overall energy management - and obtain the lowest investment, operating cost and carbon foot print.

JouleWall technology is traditional production method using known materials for building design eliminating the otherwise costly air-conditions system in buildings. The Thermo-Active-Building Systems of today is only capable of transferring 30 W/m2/floor and the invented JouleWall is capable of tripling the energy transferring capability, which is required for replacement of air-conditions systems in warmer countries.

Traditional ducting in office buildings, hotels for ventilation and temperature control covers 50% of the typical total installation cost ranging 2,000 to 5,000 Euro/m2 including heat pumps, tubing, ducting and extensive ceiling grid system. 

Design studies for 35° latitude prove that the HelioPower and JouleWall technologies combined with existing building materials and techniques save 10% in building investment and 85% in electricity consumption – for the same or better comfort.

 The concept was invented, developed and subsidized by Stobbe Tech A/S

JouleWall saw good international interest. Commercial strategies for Stobbe Tech took the direction towards biotechnology prohibiting also full focus on JouleWall. HelioPower A/S was closed 2012.

Project period: 2008-2010
