Beer factories in Germany used ice in cellars for their production throughout the year. A/C will require far more and may even heat up the cellars, so that more ice will be needed to bring them back to normal temperatures.
During WW2 there were some ideas to build landing strips on ice built as composite of coconut matting with ice, being transported to their operation area as a kind of raft. This construction was considered as being very stable and melting of ice should be reduced by insulation effect of the coconut mat.
So if thinking of transporting a huge volume of ice (e.g. from North Pole) to another place this could be an idea to follow. My idea would be to include pipes into the raft to extract the temperature continuously with brine. Well constructed the raft could be of multiple use.
It must be considered that most large cities with huge consumption of energy for air condition in summer are located close to the coast. Could become an interesting business.
