  "text": "1A The number of inhabitants is known or has been estimated on the basis of dwelling units. In this case the number of inhabitants of a building is the sum of the number of inhabitants of all dwelling units in the building:\nInh building = ∑ i = 1 n Inh dwelling unit i\n(2.8.1)\n1B The number of inhabitants is known only for entities larger than a building, e.g. sides of city blocks, city blocks, districts or even an entire municipality. In this case the number of inhabitants of a building is estimated based on the volume of the building:\nInh building = V building V total × Inh total\n(2.8.2)\nThe index ‘total’ here refers to the respective entity considered. The volume of the building is the product of its base area and its height:\nVbuilding = BAbuilding × Hbuilding\n(2.8.3)\nIf the height of the building is not known, it shall be estimated based on the number of floors NFbuilding , assuming an average height per floor of 3 m:\nHbuilding = NFbuilding × 3 m\n(2.8.4)\nIf the number of floors is also not known, a default value for the number of floors representative of the district or the borough shall be used.\nThe total volume of residential buildings in the entity considered Vtotal is calculated as the sum of the volumes of all residential buildings in the entity:\nV total = ∑ i = 1 n V building i\n(2.8.5)",
