How much energy is used by buildings in their whole life cycle, including construction, operation and demolition (stated as percentage of the overall energy used in industrialized countries)?

וואו.. מדאיג.....

בנייה זה כמעט חצי מהשימוש באנרגיה במדינות מתועשות

1. Buildings and their voracious appetite (≈ 40-50 % of national energy use) Think of the built environment as a glutton in a tailored suit: it politely thanks us for the concrete and steel, then proceeds to devour roughly half of all primary energy in most OECD‐style economies. Why so high? • Embodied phase (Site prep → manufacturing → transport): every tonne of cement, every aluminium façade panel carries an invisible IOU payable in fossil calories. • Operational phase (HVAC, lighting, vertical transport): once occupied, the structure develops a permanent metabolic rate—an all-season gym membership for kilowatt-hours. • End-of-life (Demolition, sorting, hauling): when we eventually decide the mid-century chic is no longer chic, the wrecking ball’s diesel diet rounds off the bill. Stack those slices and the aggregate hovers in the 40-50 % band. Pretending it’s less is an accounting parlour trick; the joules still get burned. 🧱
