After mucking around with this it seems that it was just a bug. I deleted the system and rebuilt it exactly the same and it worked just as I wanted it. Thanks lutinfr for your response!

I am attempting to run ApacheSim and am getting the error message "Error: Mismatch between controlled variable (temp) and module type (mixing module), node 38/1". Any ideas what I need to change? I've checked that my values in the mixing damper set, fans and sensors all line up, as well as my ...

Hi CP,

Thanks for your response. Thought about it some more and I suspect that it actually means L/s per meter squared of facade? There is another option L/s.m^2 and I guess this is what you suggested.

Thank you.

A quick one, does anyone know what l/s.m²fac mean as a unit for air exchange flow rate?

Thanks in advance.

Thanks for your reply ZapBran, I have gotten an answer elsewhere in this forum actually and others have suggested that the negative conduction gains are a result of the building fabric absorbing the heat. I had heat gains from all sources into the rooms (internal, infiltration, solar and conduction ...

Hello,

Regarding rooms marked as "Adjacent Building", I tested the adiabatic condition by modelling a room completely surrounded (all sides, above and below) by "adjacent buildings". Applying internal gains, I got non-zero conduction gains which implies that "Adjacent building" does not give an ...

Does anyone know whether the room/zone temperatures simulated in Apache>CIBSE are local maximum temperatures in the room or are they averaged room temperature values? Is there any way to model/visualise the temperature profile within a room/zone?

Thank you.

Running the CIBSE simulation for a Class 3 building (apartments) I have encountered negative conduction gains during the day when the HVAC (cooling) system is turned off. All rooms have one wall exposed to the corridor (set as an adjacent building at the design temperature in the model) and another ...
