How does LEED v4 define "high-performance building"?

LEED v4 defines a "high-performance building" as a structure that optimizes energy efficiency, water conservation, and sustainable material use. This definition encompasses a holistic approach to building design and operation, emphasizing the integration of various systems to enhance overall performance and sustainability.

High-performance buildings aim to reduce environmental impact while improving occupant comfort and well-being. They incorporate energy-efficient systems, utilize water-saving strategies, and prioritize sustainable materials throughout the building's lifecycle. This approach goes beyond just a singular focus, recognizing that maximum benefit comes from considering multiple facets of building performance, resulting in a healthier environment for both occupants and the planet.

The other options, while related concepts, do not capture the comprehensive definition provided by LEED v4. For example, while buildings powered entirely by renewable energy would certainly be sustainable, this doesn't address other critical aspects like water conservation and materials. Similarly, having green roofs can contribute to sustainability, but it does not alone ensure that a building is optimized in all key performance areas. Finally, using advanced technology, while beneficial, is not a defining feature of a high-performance building without considering the broader strategies of efficiency and sustainability.
