[Equest-users] modeling w/ limited info?

[Paul Diglio]

Mike:

I perform energy audits of large commercial and industrial sites.

I develop energy efficiency measures based on the current operation of the building, estimate the project and work with the utility companies for incentives.

I find Excel suitable for this purpose.  I have developed different worksheets to estimate the energy savings by, for example, converting a constant volume fan or pump to variable volume.

This process is different than modeling as I take actual kW readings, fan and pump RPMs, static pressures and datalog equipment and space temperatures.

The utilities want actual data not nameplate.  The more accurate the data the higher the incentive.

If you are interested, I can e-mail you a sample spreadsheet.  You need an Excel add-in called Get Psyched for the psychometric functions included.  You can download this for a free 60 day trial or purchase for $50.   No way to calculate the savings for comparative enthalpy or demand based ventilation without psychometric functions.

I have not found any utility company in the Northeast that will accept the savings calculated by eQuest.  All the calculations must be transparent and editable.

Good luck on your new endeavor, I find auditing and the opportunity to implement my own strategies very exciting and profitable to my clients.

I am a novice equest modeler having only done 4 or 5 buildings w/ simple mechanical systems. 
My firm wants to branch out beyond HVAC systems designs. We want to work with owners of existing buildings to analyze & offer energy use reduction strategies to them. In this scenario our information might be limited & so our study might be limited, as well. I find equest to be very comprehensive & perhaps not suited to a study focused on one aspect of energy consumption ( say, lighting for example). Is equest an appropriate tool in this case, or could anyone suggest a simpler tool for more limited applications?

I would appreciate any thoughts or suggestions.
Thanks
Mike
