Thermal Comfort and Energy Efficiency for Electric Buses
This new toolkit guides a successful holistic thermal comfort and energy efficiency strategy for bus operators.
What’s in this Report?
For both health and comfort, a bus cannot be too cold or too hot for passengers. But electric buses are prompting us to change how we regulate temperature.
With a combustion engine, bus operators can play it safe and put the heating heating higher in the winter and air conditioning lower in summer. Not only is this inefficient and sometimes unnecessary, but electric buses have limited energy storage capabilities and so this is no longer feasible. Given this, we must reconsider our strategy.
Across several cities, the UITP Bus Committee analysed the impact of heating and cooling on the energy efficiency and range of battery electric buses.
Contents:
- What is thermal comfort on buses
- Results of measurements under controlled environment
- Measurements on city buses in line operation with passengers
- Evaluation of measurements on city buses in line operation with passengers
- Recommendations
"The research reveals that in cold regions, heating can account for more than half of total energy consumption, as observed in cities like Stockholm, Sweden and Ottawa, Canada. Similarly, cooling in hot regions, such as Australia, can consume at least a third of the total energy."
