Multi-Zones Boundary Conditions

Hi everybody,

I have been watching the Chris Mackey´s videos “HoneyBee Energy Modelling” (thanks a lot!! they are sooo useful) because I would like to start runnig multi-zone simulations. But there is something that I don´t know/understand… Is it possible to assign just to one surface an alternate boundary condition?

I mean, through the “Honeybee_Solve Adjacencies” component i am able to assign different BC between two zones, but in that case, maybe more than a wall will change its BC.

What should I do to change the BC just to one wall?

Thanks a lot in advance

Hi Claudia,

I’ll recommend you to take a look at the following HB components:

setEPZoneCnstr

setEPSrfCnstr

setEPZoneIntCnstr

You’ll probably will need the last one, but all of them are intended to change specific zones, usually, after they get default values (but not only).

Hi Abraham,

thans a lot for your advices. I was looking to those components but as i could understand i just can use them to change the EP construction, so then their stratigraphy and characteristics of each material (roughness, thickness…).

Meanwhile I didn´t find the way to change the Boundary Conditions (Adiabatic, Outdoors…). Is it possible? If yes, can you please show me the worflow to do that?

Thanks in advance

Claudia

Claudia,

The “best” i can offer is this link.

This is a discussion i opened and Chris’s recommendations and solution are pretty good.

Hopefuly they will work for you too.
