For SBEMie purposes this dialog defines the characteristics of both lighting systems and lighting control systems, which SBEMie models using the NCM simple lighting control method.
Individual room gains are not displayed when the Method is set to SBEMie, so all lighting parameters are set in this dialog.
As the text on the above dialog indicates, all of this data are valid inputs to SBEMie. Details are provided in the VE Compliance user guide and the iSBEM 5.6a manual.
Note that in Compliance mode a Full design is required, but in BER mode the two further options of ‘Lighting chosen’ and ‘Only lamp type known’ become available.
The iSBEM manual explains this further. For all three design options, the BER mode does require a lamp type to be specified, for the purpose of the Recommendations Report.
Tick Are there destratification fans in this room? to make allowance for this feature in heating demand calculations.
Air permeability at 50 Pa (m3/(h.m2)) specifies the permeability parameter to be used to calculate the room’s infiltration rate (which in SBEMie is specified at room level).
Domestic hot water dead-leg pipe length in this room is a parameter affecting hot water distribution losses.
