In today’s increasingly complex building environments, properly planning electrical loads for Mechanical, Electrical, and Plumbing (MEP) systems is more critical than ever. As buildings become smarter, more energy-efficient, and more technologically integrated, the role of accurate electrical load estimation and coordination has evolved into a fundamental discipline for engineers, designers, and facility managers. That’s why the new book Electrical Load Planning for MEP Systems: A Practical Guide to Building Services Power Demand by Charles Nehme arrives at exactly the right moment. This essential guide demystifies electrical load planning and offers a clear, practical roadmap for professionals working across all sectors of the built environment. Why Electrical Load Planning Matters Every building—whether residential, commercial, industrial, or mission-critical—relies on stable, balanced, and well-designed electrical power distribution. MEP systems, which include HVAC equipment,...

In today’s buildings—whether commercial offices, hospitals, cleanrooms, or large data centres—HVAC systems are surrounded by sensors collecting vast amounts of information every second. Airflow, temperature, humidity, vibration, motor current, pressure—every detail is logged. Building Management Systems (BMS) and IoT platforms generate dashboards, alarms, and trend analyses. Yet despite all this data, many facilities still operate reactively. Filters clog before anyone notices. Fans fail unexpectedly. Energy bills remain high with no clear explanation. The problem is not the lack of data—it is the lack of actionable insights and clear optimisation strategies . This is where predictive maintenance becomes powerful. But collecting predictive data alone is not enough. The real challenge lies in turning that data into decision-making, operational improvements, and measurable savings. This article explains how to bridge that gap and create a closed-loop optimisation process for your HV...

An Air Handling Unit (AHU) is the lungs of a modern building, crucial for maintaining climate control, air quality, and occupant comfort. When it fails to deliver the proper air flow—whether it's under-performing or shutting down entirely—the consequences ripple throughout the entire facility, leading to massive energy waste and health concerns. This isn't just about a slightly warm room; it's a systemic failure that demands expert attention. Why AHUs Fail to Deliver Proper Air A common misconception is that AHU failure is always a sudden, catastrophic event. More often, it's a gradual decline in performance leading to "improper air delivery." The root causes are varied and often interconnected: Clogged Filters: The most common culprit. Dirt accumulation restricts airflow , forcing the fan to work harder, which wastes energy and reduces the volume of air delivered. Fan and Motor Issues: Worn belts, misaligned pulleys, or motor faults reduce the fan speed an...
