Use culture invariant conversion to lower case. Ohterwise 'I' may be converted to 'ı' (missing dot) depending on the culture/language settings (e.g. turkish) and thus several lookups fail. Using culture independent conversion to lower case still gives 'i'.

extending bus aux model: in case of electric compressor do not provide a compressor map, use a different implementation fir BusAux Module 4 that does not add power deman and no generated air

make more testcases work

use separate SSM config for cooling and heating (different system configuration, different heatpumps)
extend IACSystem with max values for heating, length of passenger and driver compartment to split heating/cooling demand
adding testcases for different HVAC configurations, expected electric and mechanic power, depending on heatpump technologies for heating and cooling

extend environmental map with efficiency for heater and heatpump cop depending on environmental conditions
map HVAC system configuration and heatpump types (driver/passenger) to a HVAC configuration for calculations
segment table: separate busaux HVAC configuration for heating and cooling depending on powertrain architecture (conv, HEV, PEV)

(couldn't load ninject assembly in .net 4.5 & .net 4.8)
