Building commissioning: a golden opportunity for reducing greenhouse-gas emissions

Tags


Commissioning is a technical process to make sure new buildings perform as designed or restores existing ones (“retrocommissioning”) to proper performance. Commissioning is best done by an expert independent of the original installer.

A 643-building study found commissioning saved 13% of energy with a 4-year payback in new buildings—but saved 16% with a 1-year payback in existing buildings.
