The potential of hemp buildings in different climates : A comparison between a common passive house and the hempcrete building system
The aim of this bachelor thesis was to study the potential of hemp buildings in different climates. The report examines and models two different energy efficient building concepts – the more common passive house and the environmental friendly hempcrete building system. These two buildings thermal pe...
