Clarify Ideal Air Loads Energy Outputs #6439

Open bbrannon4 opened 6 years ago

bbrannon4 commented 6 years ago

Issue overview

Currently the district energy outputs for ideal air loads systems are inaccurate and confusing. There is no 'energy' that really relates to the real world. Instead this just shows the 'load' required to maintain a setpoint. There are some unmethours posts that confirm confusion in the community.

I sugest removing the 'district' outputs, as well as any others that reference 'energy' and instead use the word 'loads' or create a new output specifically for ideal air loads.

Please provide links here to the referenced unmethours posts.

This was the one that prompted the issue: https://unmethours.com/question/29242/how-close-can-hvac-system-get-to-ideal-load-air-system/

And this was a recent one where the outputs caused confusion: https://unmethours.com/question/28580/get-district-cooling-consumption-even-though-i-didnt-use-district-cooling-component/

And another relevant one recently: https://unmethours.com/question/27774/my-question-is-about-the-energy-consumption-of-cooling-and-heating-by-using-ideal-load-air-system-what-is-the-value-of-cop-set-as-default-how-can-i/

I think there were more, but those were what comes to mind in recent posts. Even without those though, the standard outputs are just technically incorrect as stated using the word 'energy', and the use of 'district' just causes confusion.
