Energy retrofit saves between 18% - 23% in annual energy costs.
A recent energy retrofit project performed by GEM Energy Management in a 15 year old commercial office building yielded an 18.1% savings in annual electric costs. A similar energy retrofit project in an 18 year old industrial facility yielded 23.1% savings in annual natural gas and electricity costs.
Both projects had simple paybacks that were less than 2.5 years.
