The units in the open studio report are kBtu/h - but the official units should be MBH.
"k" is a metric abbreviation. It is not used in IP units. It's just wrong regardless of what people think makes sense. Here are some examples of what people in industry do. Both engineers and manufacturers.
Can this get corrected?
Per https://en.wikipedia.org/wiki/British...: "The unit Mbtu is used in natural gas and other industries to indicate 1,000 BTUs. However, there is an ambiguity in that the metric system (SI) uses the prefix "M" to indicate one million (1,000,000). Even so, "MMbtu" is often used to indicate one million BTUs particularly in the oil and gas industry. Energy analysts accustomed to the metric "k" for 1,000 are more likely to use MBtu to represent one million, especially in documents where M represents one million in other energy or cost units, such as MW, MWh and $." I am a die hard user of 'k' for thousands regardless of what comes after it.
If you are an "energy analyst" and don't know what MBH is you need to get fired.
@TheEnergyTutor coming to a Q&A site asking for help and then insulting someone who tries to help is not a good way to receive help in the future.
people in industry do. Both engineers and manufacturers.
The US is not the entire industry. Having worked abroad, I can confirm MBH is often confused for million BTU/h, whereas no one is ever confused by kBtuh (or kBtu/h). BEM software is used internationally, and should be designed to limit confusion.
A lot of amateurs get confused but that's not our problem. What country uses BTUs that doesn't know what MBH is?
Countries that primarily use SI units, but do some work in the US and are forced to use IP occasionally. Canada is where I experienced this.
The 90.1-2016 and 90.1-2019 IP version section 6.8.1 Tables that list HVAC equipment efficiencies are in units of tons and Btu/h. kBtu/h seems like the clearer option here rather than using roman numerals.
I uploaded some more examples of what is used in industry. kBtu may "make sense" but it's not used and it's not actually a unit.
The all mighty google has spoken. Check for yourself. None of the other comments in this thread provide any references. Only unsubstantiated personal opinions.

You have brought this up before. I still disagree.
And what about
kBtu/ft2? It's the standard unit for EUI mixing an SI prefix with an IP unit.
