High Priority for Hive 0.2!

More Energy Systems components.

Simple Equations from Energy and Climate Systems Classes. Check with Illias and make a list of which technologies would be important to have first.

Focus on PV, ST, heat pump and borehole. See equations attached. For heat pump calculate COP as a function of inlet (depending on choice of anergy source, e.g. air, borehole, ...) and outlet temperature (depending on choice of heat dissipation, e.g. floor heating, radiator, ...)

@hillias @amraladdin Some of those equations are not useful / incomplete for architecture students. "Systemdesign - Heizen/Kühlen": partly are over-simplified equations, that cannot be related to what architects deal with. E.g.:

• "Entzugsleistung Erdsonde", what are they supposed to do with P_GHE? How does it connect to how a ground-source heat pump operates?
• "Wärme/Kälte durch Wärmepumpe": It would be better to have it as E = Q / COP, since they typically know the ideal heating loads and wanna figure out how much their electricity loads increase when operating an HP.
• "Wärme durch Verbrennung": An equation telling them the total operating cost and carbon emissions based on their heating loads and energy carrier would be much more useful

In my opinion, this formula sheet needs some update, keeping in mind what would be useful for architects

[hillias]

Agreed. Please propose alternative equations with references/background material keeping in mind that the lecture slides have to be updated accordingly.

ahh, we already have this issue for it: https://github.com/architecture-building-systems/hive/issues/103

[ChrisZenhub]

discussing this issue on meeting next Tuesday (7th April) moerning 9:00 with @hillias @amraladdi and arno

[amraladdin]

Shouldn't this issue be concluded?

Shouldn't this issue be concluded?

it should, but it isn't ;( the checklist on the top needs to be completed. but that's mainly my job, so I'll remove @amraladdin and @hillias as assignees

[amraladdin]

Ok great :)

Had a talk with Martin Mosteiro. Use his methods for multi-energy-systems sizing also in Hive as a first step!

In a second phase Hive 2.0, we should add MILP models for a smarter way to size MES.

Check out his mail that he sent to me on 2020-05-28

[ChrisZenhub]

for the MVP, we have:

• CHP
• Gas Boiler
• ASHP
• PV
• ST
