Overview

Energy efficiency is the delivery of an equivalent service, comfort, or output while consuming less primary or final energy, achieved by reducing thermodynamic and conversion losses rather than by curtailing the service itself. It is quantified through metrics such as energy intensity, coefficient of performance, specific energy consumption, and the ratio of useful output to energy input across a defined system boundary. In the built environment, efficiency gains come from improved envelope insulation, glazing, lighting, refrigeration, and heating, ventilation, and air-conditioning systems, and from operational measures suited to both commercial buildings and residential stock such as student hostels. In energy supply and end use, efficiency is advanced by higher-performance conversion devices, including solar thermal collectors, photovoltaic and photovoltaic/thermal systems, nanofluid heat-transfer media, and power-electronic converters that interface generation with loads. Transport efficiency, including measures applied to heavy freight vehicles and dual-fuel combustion, addresses fuel use per unit of distance or payload. Closely linked to Energy Conservation, efficiency reduces resource depletion, operating cost, and emissions, and is assessed through engineering analysis, field measurement, and techno-economic evaluation. Work in this area spans building retrofits, renewable integration, materials for solar harvesting, and the modeling of combustion and thermal processes.
