Repurpose Abandoned Shopping Mall in Malaysia

We could repurpose abandoned mall in Malaysia for storage space rental, student housing, immigrant worker temporary housing, exhibition space or higher learning institute.

The real question here:
If we do repurposing, could our shopping mall topology survive without central unit air conditioning?

Think carefully most of shopping mall has 20-30 years of bank loans financing plans. Considering the high connectivity of Industrial Revolution 4.0,

Do you think shopping mall could sustain for another 10 years?
