At the TfL Finance and Policy Committee on 14 October 2014, a report on New Routemasters said that "TfL is currently assessing the air cooling systems on double deck buses in the fleet with the aim of improving comfort, particularly in response to especially high temperatures experienced in summer 2014. Current options under consideration include better insulation around areas such as the engine compartment, improved ventilation and remote monitoring of saloon temperatures". What were the results of this assessment and are you taking any of the three aforementioned options forward?

TfL is implementing several options which offer the prospect of more immediate comfort to its travelling passengers. This includes reconfiguring air cooling systems to provide cooled air at the lower thermostatical level of 21 Celsius to help reduce the build-up of heat, trialling solar film on windows which can prevent heat build-up by up to 5 Celsius under test conditions and fitting heat sensors to a small sample of buses. Several months of monitoring data will need be analysed to gauge the contribution these enhancements might make to double-deck buses of all types. Other options which remain under consideration include better engine bay insulation and improved ventilation in relation to the effectiveness of measures introduced to date.
