Sammanfattning
Improving energy efficiency while complying with the interior climate requirements is one of
the main challenges in electric buses. Heat Ventilation and Air Conditioning (HVAC) system
of electric buses has a rather large share of total energy consumption during driving. Compared
to conventional buses that use internal combustion engines, there is less excess heat from an
electric motor in electric buses. Therefore, improving the HVAC system’s energy efficiency
can increase the driving range of electric buses. In this master thesis calculation of the U-value
for the Volvo electric bus was performed using the GT-SUITE simulation software. The
suggestions for improving the energy efficiency of the Volvo electric bus were discussed as
well.
