Recently, someone used ChatGPT to create 10 Energy Modeling jokes and challenged someone to create better jokes
As the funniest person in the industry, definitely the only instructor with a sense of humor, I am obligated to accept the challenge.
For years, I have collected memes regarding energy modeling and performance design. I will start sharing them if this gets enough views.

Typically, default eQUEST locations install automatically, but lately, they do not, which causes an error.
The error states: The following weather file is required to perform the simulation for the selected location but was not found.
We will present multiple solutions, but first, let's note that the error looks like this:
The "install via internet" button will not work, but you can try it.
Solution Number 1: Download the weather file from the sourceThe easiest solution...
In one case study, building commissioning saved a building owner 36% on an annual energy bill of $550,000. large commercial building in a major metropolitan area. The building was constructed in the 1980s and had not undergone any significant upgrades since then. The building owner was interested in reducing energy costs and improving tenant comfort, so they hired a commissioning agent to evaluate the building's systems.
The commissioning agent discovered several issues with the building's HVAC system, including air leaks and improperly calibrated controls. Additionally, the building's lighting system was outdated and inefficient, with many bulbs burnt out or dim. The agent recommended several upgrades to the building's systems...
Building commissioning and energy modeling are two complementary processes that work together to optimize building performance and achieve energy savings. Energy modeling is a computer-based simulation of a building's energy performance that can predict how different design choices will affect energy consumption. Energy modeling can be done remotely.
Building commissioning, on the other hand, is a process of ensuring that building systems are installed and functioning as intended. Commissioning often requires an onsite visit. When these two processes are combined, building owners can achieve even greater energy savings and ensure that their building is operating at peak performance. In this blog, we will explore how building...
Building commissioning is a process that ensures that all building systems are designed, installed, and functioning according to their intended purposes. This process plays a crucial role in ensuring that buildings operate efficiently and sustainably, which ultimately saves money and energy. In this blog, we will use a few simple examples to illustrate the various reasons why building commissioning saves money and energy (and safety, and, and...)
(Sidenote: Try to find a commissioning agent based on a referral. You don't just want a box checker!)
One of the primary ways that building commissioning saves money and energy is by identifying and correcting design and installation issues early on before the...

Likely, you have wanted to smash your computer. Now, lately, many of you may not be fond of investing in the stock market - so why not invest in your workstation? If you are fortunate enough to work for a company that can upgrade your equipment, this is what I have found to be beneficial.
1) Dual monitors. Large sized. 4k preferred
I like working on a laptop but I really don't understand how someone can work with less than two monitors. I just upgraded to three of these 4k 28" Samsung monitors...

What does this have to do with Calibration?I posted a question on LinkedIn some time ago surveying modelers on what some of their biggest time sinks are when calibrating an energy model. Most every response involved getting accurate data. Not one person mentioned something that I thought would be very obvious: simulation time.
Whenever we are calibrating and we receive updated information, we have to iterate the calibration by one variable at a time, and then add the next variable and iterate. Moreover...
An eQUEST Photovoltaic question paraphrased from the mailbag
"I created a PV system in eQUEST as shown step by step in your online tutorial. However, in my test file, I can't seem to change the total energy savings. The first problem is that, even if I change the size/area of the PV panel, I can't seem to increase the total kilowatt capacity of the PV in the PS-H report. Additionally, if I increase the number of PV units, I also show no additional savings. How do I increase the PV savings?"
Answer:
Great question and you are on the right track. There's a few notable points.
The capacity for a...
It seems to me that the whole building energy simulation community has become fixated on the topic of "How to calibrate an energy model." Calibration ensures long term growth of the energy modeling industry because a calibrated model commands respect across multiple disciplines. Calibration is nearly always useful, albeit unnecessary, in many circumstances. First things first:
What does it mean to calibrate an energy model?In laymen's terms, calibrating an energy simulation means "Gathering the actual energy used by the REAL building, after the building has been fully operational for some time - usually about a year - and then adjusting energy model inputs so that the simulation output more closely approximates the energy...
