Building Integrated Energy SystemsIntegrated energy systems in the building envelope or structure that utilizes the available on-site energy resources in a way that minimizes the need for purchased energy and maintains a satisfactory indoor environment
Enhanced sun protection and cooling load control while improvingthermal comfort and maximizing daylightingEnhanced air quality and reduced cooling loads using natural ventilation schemes through an active façadeReduced operating costs by minimizing lighting, cooling and heating energy use by optimizing the daylighting-thermal tradeoffsImproved indoor environments leading to enhanced occupant health, comfort and performance
