коэффициент использования(The BOMA standard relies on two important definitions: "usable area" and "rentable area." ... Rates are quoted on the basis of rentable area. To determine the amount of rentable area leased by a particular tenant, a ratio must be established (sometimes known as a "load factor") so that each tenant will pay his proportionate share of the elevator lobbies, restrooms, corridors, and other common areas not included within each tenant's usable area. This ratio, or load factor, is determined by dividing the total rentable area by the total usable area. This will usually result in a figure of about 1.10 to 1.15. To determine a tenant's basic rent, his usable area is multiplied by the load factor, and the result (which is the rentable area) is then multiplied by his rate per square foot. Alexander Demidov)
