Hello Everyone,

My firm has an immediate opening for an Energy Modeler/Engineer. We are looking for individuals with a minimum 3-4 years experience in building energy simulation. Seeking persons with a BSME or MSME and extensive experience in energy efficiency/sustainability in commercial and residential buildings. Proven expertise in analysis of building modeling, energy codes and standards required.

Software Experience
- DOE-2, eQuest, Required

- Ecotect, IES-VE, Preferred

Salary is competitive and based on experience

Thank you,

I have a general question for the community:

Has your firm successfully completed any 2008 Title 24 documentation
using eQUEST 3.64? We have tried a couple of times and come across
errors that forced us to go another direction (EPro...) We already have
an eQUEST model set up for LEED 2009, but wanted to get an estimate of
the headache anyone has encountered before making any promises.

We've had the same issue multiple times forcing us to go the EnergyPro
route as well. There is an issue with the compliance simulation model in
3.64 that is apparently being worked on, though I've not heard of any
progress or updates in the past few months, see the below post from

Nilay Desai

Madison Engineering P.S.(MEPS) provides James J. Hirsch & Associates
(JJH) assistance on the development of the compliance analysis
capabilities for eQUEST energy analysis software. In August, 2010, JJH
released eQUEST v3.64. This version has been approved by the California
Energy Commission for compliance with California's Title 24 energy
standards for nonresidential buildings. eQUEST v3.64 also includes the
capability to automatically generate a baseline building project that
meets the requirements of ASHRAE Standard 90.1-2007 Appendix G. Title 24
compliance and 90.1 baseline building generation are performed
automatically by eQUEST using a "compliance analysis ruleset" (ruleset)
that interprets and converts the user created project. The JJH goal is
to create rulesets that can operate on any valid user project, as long
as that project can be opened in eQUEST without errors, and reliably
perform Title 24 analysis or create a 90.1 Appendix G baseline building.

The JJH team has been monitoring the eQUEST Users listserve and observed
that several contributors have reported errors in the compliance
analysis process. These errors present themselves through two steps:

1. The compliance analysis process stops, and a dialog appears stating
something like: "Compliance Analysis Error: Error(s) encountered
Evaluating Budget Conversion Rulelist ..." The dialog also allows the
user to view the errors.

2. If the user chooses to view the errors, a second dialog appears that
lists the errors. An example of an error is: "Error Assign zone to
baseline floor system: CRRule::Eval() error posting symbolic (value
4.37216e-297) result to BDL"

In almost every circumstance, these errors are the result of problems
with the compliance analysis ruleset and, unfortunately, cannot be
rectified by the user.

We are in the process of investigating and fixing bugs in the compliance
analysis rulesets. Having actual user created projects that encounter
these types of errors is invaluable to our development process. It would
be very helpful if users would provide us with any eQUEST projects that
encounter compliance analysis errors. If you are willing to help us out,
please place the eQUEST project file (with a file name format of

.pd2) and the DOE-2 input file (with a file name format of

.inp) in a compressed archive file such as .zip or .7z
format and email to eqcomp at
We will keep any submission fully confidential, only allow access to
those materials by our development group for the purpose of diagnosing
eQUEST problems that require fixing, and not release to anyone for any
purpose. In your email, it would also help if you would tell us a little
bit about your project, especially if you are trying to simulate
something unconventional, such as using the IU system to represent
chilled beams, simulating a DOAS, etc. Again, JJH and MEPS assure you
that we will use these files only for development, testing and debugging

Please note that we do not intend to provide technical assistance with
these projects, so you may not hear anything back from us except to
inform you of upcoming updates to eQUEST. However, please accept our
thanks in advance for any problem projects you are willing to provide.
On a final note, please do not reply to the equest users list with your
projects unless you want the entire list to have those projects. Email
those files directly to us at eqcomp at
