Practical insights on energy, building automation, and compliance for buildings and industry, by the Cobler team.
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.
Compliance & IncentivesFeaturedMalaysia's EECA 2024 (Act 861) made energy management a legal duty for large energy users. Here's who is covered, what you must do, and how to get compliant.
The Essay SeriesDiane Vaughan showed how NASA normalized a fatal flaw one accepted anomaly at a time. A BMS alarm page with 2,000 unacknowledged reds runs the same experiment, and alarm fatigue is the mechanism.
Compliance & IncentivesMalaysia's EECA 2024 star label grades large offices by building energy intensity. The official formula, GFA exclusions, star bands and a worked BEI calculation from real metered data.
