The four wall constructions we have modeled in our project are:
Generally, Brettstapel is a mass timber construction without making use of any nails or glue. In fact, the softwood timber posts are connected with dowels. Although currently it is manufactured in Austria, Germany, Switzerland and Norway, we have chosen this construction because of its innovative characteristic. The absence of materials such as glues makes the indoor environment healthier.
It should also be mentioned that Acharacle Primary School, in Scotland, was the first building with this construction
More specifically, for the under examination house, we have used the following structure for the walls:
U values (horiz/upward/downward heat flow)= 0.143 0.144 0.143 (partition) 0.141
U values (horiz/upward/downward heat flow)= 0.145 0.145 0.144 (partition) 0.143
U values (horiz/upward/downward heat flow)= 0.148 0.148 0.147 (partition) 0.146
U values (horiz/upward/downward heat flow)= 0.138 0.138 0.137 (partition) 0.136
It has to be mentioned, that the windows were triple glazed filled with argon with a U-Value of 1.26W/mK
