Bugs Fixed

• Solar PV measure suitability check is now correct
• Warm air system measure takes account of the fuel argument
• Hot water tank thermostat checks for presence of tank as part of suitability constraints
• Adding multiple extra fuel charges for the same fuel now works
• The balance of accounts is correctly calculated when houses with a different weight than the scenario quantum transact
• Basement floors are treated as ground floors for heat loss when in SAP mode
• Low energy lighting measure has an effect on buildings which have only incandescent lighting (previously it only worked if a house already had some low-energy lights)
• Exposed upper floor u-values are now affected by floor insulation in SAP mode

Other improvements

Documentation for the consume function, room heater suitability, hot water tank thermostat suitability and warm-air system suitability have all been improved.

Failure messages when there are problems with the remote running infrastructure should be more informative.
