The thermal bridges along the foundation and the losses towards the ground are becoming of greater importance as the general insulation level of the buildings increase. The efficiency of floor slab insulation and foundation becomes even more important when floor-heating systems are used. Despite this, not enough emphasis is put on to these parts of the building fabric, which in many cases in the past has lead to excessive losses and thus the goals of low-energy building projects were not met. The objective is therefore to develop simple cost-efficient and well-documented solutions that are easy to integrate in the building design for the building designers that are applicable for different wall construction types.
This work is going to be undertaken in close cooperation with the first dense-low rise housing project to be designed at the demonstration site.
