Jeremiah,<br><br>That is an important topic among researchers and practitioners in the simulation community for the last 20-30 years. <br><br>I made a presentation on this topic in a public EETD/LBNL seminar, A closer look at the energy performance of buildings: simulated vs. measured. Slides are available in PDF at <a href="http://eetd.lbl.gov/news/events/2011/03/03/a-closer-look-at-the-energy-performance-of-buildings-simulated-vs-measured">http://eetd.lbl.gov/news/events/2011/03/03/a-closer-look-at-the-energy-performance-of-buildings-simulated-vs-measured</a><br>
<br>I have some journal articles discussing related topics.

Dear bldg sim,<br>
<br>
I am looking for papers that elaborate on the concept of modeling, and how<br>
it correlates to actual utility data to share with people within my company.<br>
<br>
The questions keeps popping up, eg..<br>
<br>
1. How does a baseline building compare to an average building?<br>
2. How does a proposed building typically stack up against the utility<br>
bills once the building is built?<br>
3. How accurate an existing building model should be to be considered<br>
useful, and how accurate is typically possible?<br>
4. For an experimental setup what would be considered to be close enough<br>
to be considered a "validated" model?<br>
<br>
My understanding is that modeling is to show relationships between average<br>
a baseline of a chosen vintage and that of a proposed design in terms of<br>
relative percentages. For existing buildings I think that useful is within<br>
20% and typically possible is 10%. Then for a validation model, the most<br>
important factor is similar curves and close totals.<br>
<br>
If anyone has any recommended papers, or personal experience it would be<br>
appreciated.<br>
<br>
Kind regards<br>
<br>
<br>
<br>

Help Wanted - Senior Building Energy Modeler<br>
<br>
Big Ladder Software is looking to hire a senior building energy modeler to<br>
help us expand the services and software that we offer.<br>
<br>
*About Big Ladder Software*<br>
<br>
Big Ladder is a Denver-based company dedicated to providing services and<br>
software *for energy modelers*. The company name reflects our mission to<br>
"help our clients reach new heights". Founded in 2009, we are a team of<br>
engineers and computer programmers who are passionate about developing<br>
innovative open-source software tools for the modeling of buildings,<br>
transportation, communities, and all areas of energy efficiency and<br>
renewables. We primarily use the EnergyPlus simulation engine to perform<br>
whole-building energy analyses. We also offer training workshops,<br>
commercial support, and custom software development services for EnergyPlus.<br>
<br>
*Job Description*<br>
<br>
This job is for a full-time position at our Denver location. A flexible<br>
remote-working arrangement may be possible in some cases. If hired,<br>
responsibilities would include:<br>
<br>
- performing building energy analyses using EnergyPlus<br>
- providing support for our clients using EnergyPlus and our software tools<br>
- teaching training workshops on EnergyPlus and our software tools<br>
- developing training materials and tutorials<br>
- influencing the direction of new software tools for energy modeling<br>
- authoring white papers, technical papers, and blog posts on energy<br>
modeling topics<br>
- growing and leading a small team of energy modelers<br>
- developing business opportunities for new work<br>
<br>
*Job Requirements*<br>
<br>
To be considered for the job, you should be able to demonstrate the<br>
following minimum requirements:<br>
<br>
- deep expertise in using one of the main energy modeling engines<br>
(EnergyPlus*, eQUEST/DOE-2, TRNSYS, IES-VE, ESP-r, TRACE)<br>
- deep knowledge and understanding of building science and HVAC systems<br>
- excellent people skills<br>
- excellent writing skills<br>
- excellent presentation skills<br>
- ability to work independently<br>
<br>
**Previous experience with EnergyPlus would be a bonus, but not a<br>
requirement. As needed, we would train you fully on EnergyPlus and our<br>
software tools.*<br>
<br>
Finally, this might be the right job for you, if you agree with most of the<br>
following statements:<br>
<br>
- you find yourself pushing the limits of your energy modeling tools on a<br>
daily basis, and it frustrates you to no end<br>
- you have worked at a mechanical or architectural engineering firm and<br>
have performed or been heavily exposed to design work<br>
- you considered becoming a teacher or a professor at some point in your<br>
life<br>
- you have an entrepreneurial streak that has gone untapped for too long<br>
- you have been looking for an excuse to learn (and become insanely good<br>
at) EnergyPlus<br>
- you think there MUST be better ways to do software for building energy<br>
modeling<br>
<br>
