EIP Calculators Ventilation Module

Many buildings are over ventilated most of the day. The EIP calculates the heating energy savings and payback period of energy conservation measures installed in your specific building compared to a prescriptive baseline. Results are based solely on the handling of the ventilation load and so are conservative.

Ventilation energy conservation measures...

The EIP ventilation module includes:

  • Adding a damper and sensors for demand controlled ventilation
  • Adding a heat recovery unit
  • Installing higher efficiency HVAC equipment
  • Adding motorized dampers in louvers
  • Taking advantage of natural ventilation

Lee Loebe, Pyramid Heating - This tool allows us to show the customers how much energy they will save.

Milo McCoy, Viking Heating and Sheetmetal - When you can show customers you can save them money -

Ruben Willmarth, Carrier Corporation - This is a great tool for Design/Build contractors

EIP produces usable, credible and code-compliant results performing the tasks of an engineer for contractors

EIP uses inputs contractors and building owners familiar with their building will know.
