Hi Brian,

Apologies for the delayed response. 

I'll have some discussion with our internal team regarding this functionality and will update you accordingly.

Hi Brian,

I understand you are referring to the system types displayed in the compliance documentation, is that correct? If so, these outputs are 100% defined by the SBEM calculation engine so we would not be best placed to comment on this. It is important to remember that Energy Simulator is an interface to SBEM engine: 

An important note on the PartL calculation - OpenBuildings | AECOsim | Speedikon Wiki - OpenBuildings | AECOsim | Speedikon - Bentley Communities

Your accreditation scheme provider would be much better placed to advise, or alternatively you can reach out to BRE themselves here. As they are the ones who define SBEM calculation methodologies they will be able to clarify for you.

Hi Shane,

I have met a similar problem and I am not sure if this is related to the SBEM calculation engine or Energy Simulator. Hope its fine to ask here.

I copied the lighting parameter from the notional building to the proposed building and try to compare the results in Part L calculation in which it is supposed it should come out with the same . However, it didnt and the notional results is still much lower than proposed case.

I input the lighting parameter under 'Lighting' and 'Lighting Output' under Room Data.

Do you help on this?

Thanks

Brian
