Practical insights on energy, building automation, and compliance for buildings and industry, by the Cobler team.
TNB Bills & TariffsMaximum demand is billed on your worst half-hour of the month. Under RP4, the old MD charge split into a Capacity Charge and a Network Charge - here's how it works.
BMS & Building TechnologyLoRaWAN gets energy data off scattered meters with no cabling and no per-device SIM fees. How it works - in plain analogies - and why it suits large-site energy monitoring.
TNB Bills & TariffsThat small 1.6% KWTBB line on your bill is the Renewable Energy Fund levy. What it funds, who pays it, and the 2025 change that lets some businesses stop paying it.
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.
The Essay SeriesA building is a structure in a slow, constant argument with entropy. On the physics of why everything you operate is quietly falling apart - and what it means to fight 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.
Energy Monitoring & AnalyticsRunning a portfolio means seeing every building on the same terms at once. Multi-site energy management is the difference between knowing which sites waste money and guessing.
TNB Bills & TariffsFeaturedA TNB commercial bill isn't one number, it's seven separate charges, and some you can cut while others you can't touch. Here's how to read each line and find the leverage.
BMS & Building TechnologyTwo buildings with identical hardware can run 20% apart. The difference is BMS design - sequences, sensors, open protocols, and data an operator can use.
