Fads, Frauds and Fallacies have plagued the transition to renewable energy. We aim to make a difference.

The best way to make economic sense of energy retrofitting is to rigorously make decisions only based on maximizing NPV while minimizing GHG-emissions. 

  • Consider financing and incentives only if the case makes sense: various incentives sometimes can cloud decisions, if the analysis is not done carefully.
  • Great financing cannot make a bad project good, it can only make a good project better.
  • Energy retrofits are capital decisions that must be evaluated on a life-cycle basis, usually 30 years, and holistically.
  • Payback of equipment is a valid measure only if that equipment is independent of any other equipment. Example: a water heater is independent only so long as energy storage does not enter the equation, so you should never replace a water heater without reference to the whole infrastructure.
  • Marginal energy savings and payback is only valid in a maintenance model that does not involve any structural changes, nor compromises the options for future changes.
  • Leasing equipment even if it's cash flow positive cannot be substituted for a proper investment decision.
