What is a “retrofit”?

A retrofit project consists of implementing energy efficiency measures to reduce a facility’s energy consumption. Investment in energy efficiency measures generates returns through energy bill savings. These measures typically focus on:

  • Installation and optimization of existing cooling equipment (e.g. thermostats, pumps, variable frequency drivers)
  • Building envelope (e.g. window shading, wall insulation, window double glazing)
  • Installation of energy efficient lighting (e.g. CFL, LED, metal-halide) and optimization of lighting management systems
  • Building management systems (BMS)

Contracting model

There are two kinds of contract models, a guaranteed savings model and a shared savings approach:

  • The guaranteed savings contract is when the ESCO promises the end-user that a certain amount of savings will occur. The ESCO only receives payment if that promise is upheld.
  • In a shared savings scenario, the ESCO and the end-user split the savings between each other. The ESCO’s portion goes toward paying down the costs associated with the retrofit.
