The document discusses performance-based procurement for building projects. It provides examples of how owners can define project goals and energy targets to guide design teams. Key aspects include categorizing goals as mission critical, highly desirable, or possible; setting clear and adjustable energy use targets; and establishing modeling guidelines and schedules for design teams to validate performance goals are met. The intent is to accelerate high performance building outcomes through the procurement process.

RFP and contract language
PROJECT GOAL LIST: Project goals help design teams prioritize their focus on the MEP and building performance design.
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

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
