Goals are categorized in three main sections: Mission critical goals - required by contract and critical to success Highly desirable goals - not required by contract and have influence on the recommended design If possible goals - influence recommended design and are considered highly beneficial if included in the solution • Maximum energy target of 45 KBTU/gsf annually; lower is preferred • LEED NC version 4, Silver Certification • Superior occupant comfort • 100% of occupied spaces physically or visually connected to nature • Living Building Challenge (LBC) 3.0 Feasibility Study MISSION CRITICAL HIGHLY DESIRABLE IF POSSIBLE • Living Building full certification • Net Zero Energy Design • Maximum energy target of 35 kBtu/gsf annually; lower is preferred • Best in class Energy Star equipment or best in class energy efficient equipment • Passive design strategies (i.e. daylighting, passive solar heating, etc.) • Achieve ‘retreat-like’ feel using biophilic design principles • Low recycled air content • Strong HVAC response to quickly changing occupancy (limit precooling with air) • Usable daylight in all occupied spaces • Geothermal system • Design features that create an interactive sustainable learning experience • Exceed LEED NC version 4, Silver Certification
