It's not unusual in northern countries. For example the tropical house at the Cotswold Wildlife Park is a converted greenhouse, I believe it was originally used for a grape vine in the walled kitchen garden of Bradwell Manor. It still has a large glazed roof and houses a range of tropical birds including crowned pigeons, roulroul partridges, bleeding heart doves and speckled mousebirds, plus Rodrigues fruit bats and sloths.
In high summer, these exhibits need ventilation and some shading on the glass to prevent overheating.
