The <VE> contains powerful solar analysis capabilities, including ETTV analysis using simulated solar and shadow projection data. This section of the navigator prompts the user to create both local (on-building) shading devices as well as surrounding external shading objects. Only local external shades will be used in the ETTV calculation for the proposed building. Topographical shades/Adjacent buildings will be taken in account as for the shadows they cast on the building, but only for the energy modelling results (if chosen by the user; this choice will need to be justified to the assessor during the energy modelling assessment); they will not be taken in account in the ETTV computation.
