    Sammanfattning : The world is experiencing increasing energy usage owing to environmental impacts suchas climate change, Ozone layer depletion, and global warming. Energy usage is primarily categorized into transport, industrial, residential, and service sectors, with the transportation and industrial sectors taking up a considerable chunk of the energy use; Buildings partly determine the use of energy globally.

    Sammanfattning : The goal of this thesis is to find a contribution to the problem of implementing additional insulation without disrupting the internal and external appearances of the building that need to be kept. With this we intend to find out which methods would be most prudent as well as finding out what effects these changes could have on the energy efficiency and the internal climate of a house. LÄS MER
