Table 1.

Condition, requirements and considerations related to the rooms; structures; and systems affecting ventilation strategy

Structure/system	Consideration	Requirements
Basement	The basement is damaged in multiple locations. Excess moisture is measured and microbial smell noted in several places	The damaged structures of the basement need to be repaired. It must be ensured that the potential impurities, even when the basement is repaired, do not enter the upper floors through shafts. Primarily, facilities for active use should not be located in the basement. Instead, building services equipment or storages may be located there
External envelope	The external envelope might be microbially damaged	Due to potential microbes inside the envelope, negative air pressure in the rooms should be avoided, excluding the rooms with a moisture load. It is not possible to block up all of the air leakages
Two-layered intermediate floor	The intermediate floor contains organic filling, which might have become moist	It must be ensured that if the air pressure changes, the organic filling of the intermediate floors does not spread impurities, harmful for health, into the indoor air
Natural ventilation shafts	Ventilation shafts are located next to the doors of classrooms
Air inlet	The size and the number of replacement air valves are deficient
Ventilation	The residential wing has rooms without any ventilation system
Heating system	The operation of the heating system is deficient
Other technical building services	The majority of the building service equipment needs to be replaced. It might be possible to preserve heat pipes; radiators; and the exhaust shafts of natural ventilation
Lift		The school needs to be accessible for disabled pupils and thus a lift must be built. However, the lift should not be built into the basement, as the potential impurities from the basement might enter into the upper floors
Attic		If air supply units are located in the attic, the incombustible floor needs to be taken down and the roofing deck requires steel holders
Shower rooms		Currently, cramped shower rooms are located in the basement. It must be explored whether the shower rooms could be located on the first floor. Thus, a lift will also not be needed in the basement
Classrooms	The existing classroom division is fairly suitable for new educational requirements
