Impact through awareness and reduction

Your energy journey starts with us

"We help clients improve their energy and environmental impact by understanding, optimising and reducing their electricity usage."

Who we are

The GreenX team has expertise in energy efficiency, energy data modelling, implementation energy retrofitting projects, and business networking.

There are three main strengths that the key people in the team bring to the together – these are academic, commercial and governance strengths. There are the two professors who bring the academic strength in research with both technical and strategic support. There is an experienced entrepreneur who has financial and economic experience from starting, running, and selling successful companies – bringing the commercial strength. Lastly, the governance and administrative strengths are brought by the US enterprises.  The running of the company is done by an entrepreneurial young academic familiar with the energy field.
