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...

If you are reading this and you're on this website, there's a certainty that you have had computer issues interfere with your bottom line. 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...

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...

From the mailbag:

An energy-models.com trainee asked a great question: Can I determine the individual energy consumption of an individual room or zone?

There are multiple options, from creating custom hourly reports and load tracking, but that gets complicated in a hurry. The answer is not perfect but the main thing to do would be create a submeter. 

If a user wants to truly isolate the energy of an individual room, it depends if the room has a room level fan and room level cooling. Otherwise, you can't necessarily determine the exact impact of a room. You could potentially estimate that if a room at 600 cfm of a 6000 cfm fan, that it would be 10% of the fan energy but really only works in the...
