The concept of 'active' versus 'passive' energy strategies is fundamental to energy efficiency and sustainable design. Active strategies involve the use of mechanical systems or technology to produce energy or improve energy efficiency, such as heating, ventilation, air conditioning, and renewable energy systems like solar panels or wind turbines. These systems actively collect, convert, or transfer energy, typically requiring a power source and maintenance.

On the other hand, passive strategies harness the inherent qualities of a building's design to maximize energy savings without relying on mechanical systems. This includes things like strategic placement of windows for natural lighting and ventilation, appropriate insulation, thermal mass to regulate temperature, and the use of overhangs to control solar gain. These strategies take advantage of the surroundings and the building materials to minimize energy use efficiently.

By understanding these definitions, it becomes clear that the classification of active strategies as reliant on mechanical systems and passive strategies as leveraging building design captures the essence of their respective approaches to energy management.
