View out – alternative method of compliance for fixed workstations - KBCN1484

In relevant spaces that include fixed workstations* (such as a built-in cash registers or reception desks) an alternative method can be used. This is based on the number of compliant workstations. For instance, where the requirement is for 95% of the relevant area to comply, 95% of the fixed workstations must have a compliant view out, rounded up to the nearest workstation.   Example A retail assessment has 35 built-in cash registers, 95% of which must comply with the view out criteria. 35 x 0.95 = 33.25, rounded up to 34. The requirement is met for this area if 34 registers comply with the criteria.   Where an asset includes a mix of relevant areas; both fixed workstations and flexible areas, compliance for the whole assessment must be demonstrated for all areas, as appropriate, based on either area or number.   *freestanding desks and other items of moveable furniture cannot be considered as fixed workstations, regardless of whether their locations are pre-determined.

View out – Calculating the glazing to wall ratio - KBCN1506

This should be calculated based on the glazed area of window, expressed as a percentage of the area of the external wall in which the window sits. Where the ceiling height of the room is unusually high, relative to the window height, the wall area can be calculated based on a standard ceiling height for the building type.

View out – relevant areas - KBCN0268

The aim of the View Out criteria is to allow occupants to refocus their eyes from close work. Relevant areas are spaces where close work in a fixed position is carried out for sustained periods of time. The view out criteria are therefore not applicable to occupied areas such as meeting rooms, or other spaces where such close work is not being carried out. Where rooms contain areas of different functions, only relevant areas should be assessed. In this case a notional line can be drawn on the plans and calculations made based on these relevant areas only. However, spaces such circulation routes or other transient spaces within a relevant area can only be excluded if the route or area is clearly defined by the building layout. If this is arbitrary or based solely on a proposed furniture layout, it cannot be excluded. Features of the building layout which may be considered as dictating a function area would include, for example, the position of doors or fixed furniture such as a reception desk or canteen servery.
07-Oct-2022 Additional paragraph added to clarify how function areas must be defined. 
21-Sep-2022 General principle of 'relevant area' added, and applicability of KBCN extended to BIU V6 Commercial.
