Why do busses have white tops

The white roofs on modern buses have grown in popularity as a simple and effective means of keeping buses cooler during the hottest months of the year.

The silver Honda Civic shell SR 0. A silver or white shell would allow for a lower-capacity air conditioner as well. The cars were run through five identical cycles of soaking in the sun. Each cycle consisted of an hour with the air conditioners off, followed by a half hour of cooling with the air conditioners running at maximum.
