  The rapid rise of artificial intelligence (AI) workloads has fundamentally transformed how modern data centers are designed. Traditional air-cooled facilities were never built for the sustained high densities and heat loads generated by today’s AI accelerators, such as GPU clusters and custom silicon. As AI computing scales, two innovative concepts are emerging as essential pillars for future-ready infrastructure: hybrid cooling systems and vertical silo architectural design . AI workloads generate significantly more heat per square foot than conventional IT processing. Conventional air-centric cooling strategies are struggling to keep pace with heat densities exceeding 100 kW per rack, leading to inefficient energy use and thermal bottlenecks. Hybrid cooling bridges this gap by combining the simplicity of air cooling with the efficiency of liquid cooling. Hybrid systems dynamically allocate cooling modes — air for lighter workloads and liquid (often direct-to-chip or rear-door ...

The AI revolution is reshaping data center design — and nowhere is that more evident than in cooling. Modern AI workloads demand unprecedented compute power, pushing server racks into the 50–100 kW per rack range or higher. Traditional air-cooling techniques simply can’t keep up with the explosive thermal loads these systems generate, forcing engineers and operators to rethink how heat is managed at scale. ( Business Wire ) Conventional air cooling — involving raised floors, CRAC units, and hot/cold aisle containment — once handled modest loads of 5–15 kW/rack. But AI clusters packed with GPUs and custom accelerators produce far more heat. Air becomes inefficient as speeds reach limits and energy costs climb, making it increasingly unsustainable for racks beyond 50 kW. ( datacenters.com ) Liquid Cooling Takes the Lead To meet these demands, data centers are rapidly adopting advanced liquid-based cooling strategies that can handle intense heat densities with greater energy efficiency: ...

But that’s changing fast. Robotics and automation are reshaping job sites, workflows, and the very nature of how we build — from foundations to finishing touches. The book Robotics and Automation in Construction Sites provides a comprehensive guide to this monumental shift, exploring both practical and visionary aspects of introducing automation to construction. ( Amazon Italy ) 🏗️ Why Robotics Matters Now Construction productivity has lagged behind other industries because most work is manual and site conditions vary widely from project to project, making automation difficult. But with labour shortages, rising costs, safety concerns, and growing global infrastructure dema...

  In today’s rapidly changing climate and market environment, energy‑efficient buildings are no longer a luxury — they are a necessity. With regulatory pressure rising and tenants increasingly demanding lower operating costs and healthier indoor environments, the construction industry must shift from traditional siloed workflows toward truly integrated design methodologies. The Integrated Approach to HVAC and Building Envelope: A Strategy for Net‑Zero Ready Construction , a guide by Charles Nehme , delivers a concise, powerful roadmap for making that shift. ( play.google.com ) Why Integration Matters Historically, building design has treated the HVAC system and the building envelope as separate disciplines. Architects finalized the envelope, and only afterwards would engineers size mechanical systems to meet the resulting loads — often leading to oversized equipment, higher costs, and ongoing energy waste. The integrated approach redefines this paradigm by treating the envelope ...

By Charles Nehme 80 pages • Professional & Technical • $35.26 on Google Play ( Google Play ) In a world where energy efficiency and environmental stewardship are no longer optional, Heat Recovery From All Processes stands out as a practical, engineer‑focused guide to harnessing energy that’s traditionally wasted in everyday systems. ( Google Play ) 🌍 The Big Idea: Turn Waste Into Value Every building, industrial facility, and building service system generates heat — but most of it simply escapes into the atmosphere. Whether it’s warm exhaust from a kitchen, heat from a laundry unit, server room cooling losses, or industrial exhaust streams, this wasted thermal energy represents a huge, under‑utilized opportunity. ( Google Play ) Charles Nehme’s book tackles this challenge head‑on. Instead of letting process heat escape, this guide shows how engineers and designers can capture, channel, and reuse it — reducing energy bills, lowering carbon emissions, and improving system p...

  Maintaining proper humidity inside a greenhouse is essential for achieving healthy plant growth, preventing disease, and ensuring optimal yields. Humidity plays a major role in plant transpiration, nutrient absorption, and overall plant physiology. When humidity is too high, mold, mildew, and fungal diseases can spread rapidly. When it is too low, plants lose moisture faster than they can absorb it, resulting in stress and reduced productivity. Modern greenhouses rely on humidity sensors, ventilation systems, misting units, and automated controls to maintain a stable growing environment. A key element of successful humidity management is using real-time monitoring tools—such as the sensor shown in the image—to track moisture levels and trigger corrective actions. Effective humidity control strategies include proper air circulation, adjusting temperature setpoints, integrating dehumidification when needed, and managing irrigation practices to reduce excess moisture. These practi...
