EIP Answers Your Energy Questions...
EIP bridges the gap between deemed energy conservation measures and expensive engineering analysis.
With the EIP, a contractor can answer the questions clients have about energy savings recommendations:
A Tool For Contractors and Others Who Service Commercial Buildings...
- Why should I spend more money?
- How much will I save?
- What is the payback?
Most energy audit tools are too expensive or complex to be used effectively by small
Engineer in a Pocket (EIP) is a cost effective, high-powered calculator
that puts the power of site-specific engineered analysis in the hands
of those who service commercial buildings such as restaurants,
schools, office buildings, and correctional facilities.
A Microsoft Excel Front End with Engineering Software Behind...
Contractors know they can save customers money on their energy bills,
but building owners require independent, reliable analysis before they will invest in
energy conservation. With the EIP, customers can see for themselves how long it will take for energy conservation measures
to pay their investment back.
The EIP user interface is Excel-based for your convenience and familiarity.
Enter your data and then click the "Calculate" button to perform computations
for your specific building using hourly weather data at your site.
Graphics and tables that demonstrate the cost effectiveness of your proposal
are generated on the spot to deliver to your customer.
EIP includes modules that perform complex analyses of mechanical measures using site specific data, such as:
- Adding a damper and sensors for demand controlled ventilation
- Adding a heat recovery unit
- Installing higher efficiency HVAC equipment
- Adding motorized dampers in louvers
- Adding programmable thermostats
