You could tag all internal faces as 'internal wall' or 'ignore' (in the case of double floors or ceilings).You could redraw a simple outline of the complex building.

If you have a complex model with double-faced elements, here are some ways to manage these: This is not relevant for walls, ceilings and floors in daylight analysis only, as for daylight we are only interpreting opaque and transparent faces, which either block (and reflect) or transmit light. a wall, roof, ceiling or glazing modeled with thickness, then energy transfer will be calculated across both surfaces, leading to incorrect results. If you tag two surfaces that are parallel to each other, e.g. To orientate your building correctly, Sefaira will assume that the default green model axis always points North.īoth energy and daylight analysis rely on a realistic floor area, and also a realistic internal ceiling height to calculate results correctly.Įnergy analysis assumes that any surface tagged as 'wall' (for example) will have all the physical properties of an actual wall with corresponding thickness. If the model is placed far away from the origin, this might interfere with both the daylight and energy simulation.

If you are running into error messages related to Sefaira being unable to process your model correctly, this is likely down to an issue with the model setup.Īside from the checklist below, please also follow this guide to ensure that your entities are tagged correctly.ġ) Always place your model at the origin and orientate correctly Below is a checklist to help with setting up your model for Sefaira analysis, both to avoid errors and to ensure that your results are correct.
