But here’s the thing, because it was designed not to have air-con, the electricity supply isn’t up to providing the necessary power.
Sounds like the developer did a cheap and nasty job with fantasy claims about passive cooling. And was allowed to get away with a deficient power supply.
All good if it works but since it’s not, are those whose residence missed out on the design benefits (which they surely paid for) doomed to suffer for ever?
Probably time to get a copy of the resident’s roll and make contact with your fellow residents and see who’s suffering in the heat. Then, let the fun begin. Hopefully you’ll be able to cool down again in the near future.
