A high-performance building is a structure that is designed, constructed, and operated to maximize the efficiency of its occupants, reduce its environmental impact, and improve the health and well-being of its users. High-performance buildings are designed to reduce energy consumption, reduce water consumption, and improve indoor air quality. They also strive to reduce the environmental impact of the building’s construction and operation, and are designed to be resilient to climate change. High-performance buildings use advanced building products and materials, such as insulation, air sealing, and high-efficiency windows and doors, to reduce energy consumption and improve indoor air quality. These products are designed to provide a high level of thermal performance, airtightness, and moisture control, and to reduce energy costs. High-performance building products are also designed to be durable and low-maintenance, and to last for many years.
