Identified thermophilic actinomycetes contamination of the forced air systems as the sensitizing agents for most of the cases of hypersensitivity pneumonitis in eight patients. Concludes that patients should avoid the contaminated systems and use corticosteroids in severe cases as therapy for the disease.
The prediction of energy use, air flows and temperatures in different rooms of a building andat different climatic conditions is very important, especially when evaluating new conceptsfor heating and ventilation systems in combination with different building envelopeconstructions. A thorough system analysis considering coupled air flow and thermalcalculations becomes very complex if e.g. thermal bridges and dynamic conditions areconsidered.
