Commissioning – the most cost effective measure?

Lessons learned • 17%+ savings in energy saving measures very possible • Refurbishment can significantly transform working environments but…

• you never know what problems you’ve got until you open up • builders believe the old adage “out of sight is out of mind” • without attention to detail, the air tightness value will be poor • commissioning (not just at handover but for the life of the building) • simple building user guides
