Passive heating systems

Minimum energy saved building designing is assuming an ever-greater importance in modernbuilding practice because of cost of fosil fuel consumption. Occupants and owners of modernbuildings ask for healty and stimulating working enviroment. However, there are stilrelatively few buildings in which passive systems have actually been realized, and there isstill too little experience of their behaviour in operation.In this paper we worked on the cheaper and enviromental solutions in buildings by using solarenergy. Solar enery using especially by passive way, will suply us to reduce fuelconsumption. In this peaper we tried to explain the passive heating ways and concreated oneway with the others. We also worked on a real school class in stanbul city in order tomeasure the walues of the real conditions.Keywords: Passive heating, solar heating, phase changed materials (PCM), naturalventilation, solar chimney
