Practical insights on energy, building automation, and compliance for buildings and industry, by the Cobler team.
Industry GuidesHalf a mall's electricity runs through the chiller plant, and one festive Saturday half-hour sets the RP4 demand charge. A practical guide for Malaysian mall operators: load split, tenant billing, the measure stack, BEI benchmarks and EECA.
The Essay SeriesEvery plant room runs on maps that quietly stopped matching the building: as-builts, BMS graphics, single-line diagrams. What Korzybski, Borges and a spinning fan icon teach about which maps to trust.
TNB Bills & TariffsFeaturedMaximum demand is the quiet line item inflating Malaysian electricity bills. Under TNB's RP4 tariff, cutting TNB maximum demand charges is now worth roughly RM89-RM97 per kW, every month.
The Essay SeriesEvery plant room polices fences it never built: the 6°C lock, the untouchable schedule, the 2014 override. Chesterton's fence explains why — and trend data is how you take one down safely.
Industry GuidesWhere a Malaysian hotel's energy really goes and how to cut it without touching guest comfort: chiller share, room setbacks, RP4 demand peaks, ToU fit, EECA and a real Marriott retrofit.
Energy Monitoring & AnalyticsWhat predictive maintenance really costs and saves: ISO 10816/20816 vibration limits in mm/s, sensor prices vs downtime costs, and a worked ROI example for a Malaysian plant under RP4 and EECA.
The Essay SeriesWhen kW/RT, OEE or M&V savings become targets, the reporting drifts. Why the fix for gamed energy KPIs is un-gameable instrumentation, not fewer numbers.
TNB Bills & TariffsTNB ToU under RP4: peak is 2pm-10pm weekdays only; nights, weekends and 15 public holidays are off-peak. What the myTNB 6-month warning means, the off-peak maximum demand exemption, and how to model a switch with 30-minute interval data.
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.
