12 What is the LEED System? LEADERSHIP in ENERGY and ENVIRONMENTAL DESIGN A leading-edge system for certifying DESIGN, CONSTRUCTION, & OPERATIONS of the greenest buildings in the world Scores are tallied for different aspects of efficiency and design in appropriate categories. For instance, LEED assesses in detail: 1. Site Planning 2. Water Management 3. Energy Management 4. Material Use 5. Indoor Environmental Air Quality 6. Innovation & Design Process

13 Integrated Design Owner Designer Project Team Supplier Contractor

14 Integrated Design Process Used for Mars Hill Day Hall charette Adapted by SDCS from: ANSI/MTS 1.0 Whole Systems Integrated Process Guide (WSIP)-2007 for Sustainable Buildings & Communities

15 Life Cycle Costing $90,000 $80,000 $70,000 $60,000 $50,000 $40,000 $30, spaces with FCUs 72 dorm rooms 4 conference rooms 9 kitchen/lounges 15 minutes unoccupied setback point 1 (+/- 5 ) 8 hours unoccupied setback point 2 (+/- 10 ) Total additional cost = $85,000 $20,000 $10,000 $ Integrated Design Checklist

16 Life Cycle Costing $90,000 $80,000 $70,000 $60,000 Utility savings are realized year after year for the life of the building. $11,700 annual savings with FY 06 energy rates. $50,000 $40,000 $30,000 $20,000 $10,000 $ Integrated Design Checklist

17 Life Cycle Costing $90,000 $80,000 $70,000 Engineering and Utilities department projects utility rates will continue to escalate. $60,000 $50,000 $40,000 $30,000 $20,000 $10,000 $ Integrated Design Checklist

18 Life Cycle Costing $350,000 $300,000 Utility savings over the life of the building. $250,000 $200,000 $150,000 $100,000 $50,000 $ Integrated Design Checklist

19 Life Cycle Costing $350,000 $300,000 The additional cost will pay for itself in 6.72 years with projected utility escalation. $250,000 $200,000 $150,000 $100,000 $50,000 $ Integrated Design Checklist

20 Energy Modeling Energy modeling utilizes computer software to simulate the physical behavior of a building over time utilizing building design / construction data and user provided assumptions. What is Energy Modeling?

21 Q = U x A x T What is Energy Modeling?

22 U x A x T Q = U x A x T Q = U x A x T Q = U x A U x A x T Q = U x A x T Q = U x A x T Q = U x A U x A x T Q = U x A x T Q = U x A x T Q = U x A U x A x T Q = U x A x T Q = U x A x T Q = U x

23 Energy Modeling Ongoing / Continuous commissioning is a formal process for continuous optimization of building systems operation and control for an existing building.
