Practical insights on energy, building automation, and compliance for buildings and industry, by the Cobler team.
HVAC & Chiller PlantsChiller plants get the attention, but the air side - fans, ducts, AHUs, FCUs - runs its own energy bill and decides comfort. Where air-side energy goes, and how to cut it.
HVAC & Chiller PlantsDelta-T is the hidden lever on chiller plant efficiency. Here is why it decides kW/RT, what causes low delta-T, and how to tune a plant for the best efficiency.
HVAC & Chiller PlantsBuilding cooling is a relay between the water side (chillers, pumps) and the air side (AHUs, coils), meeting at the cooling coil. Here's how they connect - and fail.
HVAC & Chiller PlantskW/RT is the one number that tells you how efficient a chiller plant is. Here is what good looks like in Malaysia, what drives plants off it, and how to fix it.
HVAC & Chiller PlantsAir-conditioning often runs to half a building's energy in the tropics. The biggest HVAC optimization levers for Malaysian operators, with worked numbers and TNB RP4 impact.
