Appendix C (Mandatory) Rules for calculating the total area of buildings, area of premises, total structural volume, footprint area and number of building floors during design Total area of the building shall be determined as a sum of floor areas measured within the limits of internal finished surfaces of external walls at the floor level (not taking into account dodge boards) plus area of mezzanines, passages leading to other buildings, loggias, terraces, galleries and balconies. Area of spaces that are several stories high (atria), internal staircases, lift and other shafts shall be included in the total area within the limits of one floor only. Area of attic floor shall be measured within the boundaries of external wall internal surfaces and attic walls adjacent to loft spaces.

Area of attic floor premises shall be calculated with application of simplification factor of 0. 7 within the sloping ceiling (wall) area up to 1. 5m when the gear is 30°, up to 1. 1m when the slope is 45° and up to 0. 5m when the slope is 60° or greater. 3 The total structural volume of buildings shall be determined as a sum of structural volume above the level of ± 0. 00 (above-ground part) and under this level (underground part).The total structural volume of building above-ground and underground part shall be determined within bounding surfaces, enclosing structures, skylights, domes, etc. starting from the clear floor level of each part of the building, whereas protruding architectural and structural elements, basement channels, porticoes, terraces, balconies, driveways an d spaces under buildings installed on supports (clear spaces) and basements under buildings shall not be taken into account. 4 Building footprint area shall be determined as area of horizontal section along building external contour at plinth wall level, including protruding elements. Footprint area of buildings installed on posts and driveways under buildings shall be included. During determination of a number of building storeys, all above-ground storeys shall be counted, including mechanical and attic floors, as well as semi-basement floor with top of ceiling structure higher than the grade level by at least 2m. Basement under the building, regardless of its height, shall not be included in the number of above-ground storeys. If the number of storeys in different part of the building is not equal or if the building is built on a site with a slope that results in increase of the number of storeys, the number of storeys shall be determined for each part of the building separately. If the number of storeys is being determined to calculate the required number of lifts or floor area within a fire compartment in accordance with Table 6. 4, mechanical floor located above the top floor shall not be taken into account.
