The American Society of Heating Refrigerating and Air -Conditioning Engineers. Biophilic design. A design approach to architecture that seeks to connect building occupants more closely to nature. Biophilic designed buildings incorporate things like natural lighting and ventilation, natural landscape features and other elements for creating a more productive and healthier built environment for people. Circular products. Products that operate within the circular economy model i.e. those products that have reduced or completely no need for virgin resources and are designed with the end of their life in mind. Energy Star. Energy Star ratingsystem (use latest edition of rating system at time of submittal of permit application to the Building Division). ENVISION. Sustainable infrastructure rating system developed by the Institute for Sustainable Infrastructure (ISI . FGBC. Florida Green Building Coalition (use latest edition of rating system in effect at time of submittal of permit application to the Building Division). GBI. Green Building Initiative. Green design practice.
