Our mission is to empower people, organisations and communities in making the transition to a low-carbon, resilient future


XD Consulting is an integrated sustainability consultancy providing multi-disciplinary advice and support in the area of renewable energy and energy efficiency. It was created by Xavier Dubuisson Eng. MSc. in 2007 on the basis of his now 20-year experience as a sustainable energy engineer having worked with leading organisations in this field in Ireland, Belgium and other European countries. The consultancy was incorporated as XD Sustainable Energy Consulting Ltd in 2011 and continues to grow its range of services and portofolio of clients in Ireland and abroad

Our approach to delivering services is based on a set of core principles:

  • Providing know-how built on experience, backed-up by ongoing research;
  • Engineering innovative, elegant and reliable solutions;
  • Communicating effectively with our clients and responding to their needs, context and aspirations;
  • Putting sustainable use of resources at the core of what we do and how we do it;
  • Delivering cost-effective services and uncompromised quality, consistently;
  • Facilitating positive change for our clients, our environment and communities locally and globally.

Over the years, we have developed strong partnerships with a network of leading experts from diverse backgrounds and complimentary disciplines at international level. No matter how big or complex your challenges are, XD Sustainable Energy Consulting will embrace them as its own.
