A shopping mall where the chillers run flat out, the transformer hums a little louder than it should, and nobody thinks to connect the two, until the day the building goes dark. Or worse, the day something sparks.
This is the quiet failure playing out across offices, hospitals, hotels and factories in cities all over Nigeria right now. Not because the equipment is bad. Because the people who designed the air conditioning and the people who designed the electrical system never sat in the same room.
Two Systems, One Building
Here is something most facility managers only find out the hard way. HVAC and electrical are not two separate trades that happen to share a building. They are one system that has been treated like two for far too long.
Every HVAC system running in a commercial building in Nigeria, the chillers, the air handling units, the VRF units, the cooling towers, is at its core an electrical load. A heavy one too. Cooling is usually the single biggest draw of power in any commercial or industrial building. When the electrical design does not account for that properly, wrong cable sizing, poorly distributed panels, weak protection, no real coordination between the mechanical and electrical teams, the problem stops being about
