1 LEED for Existing Buildings Overview Ken Sidebottom, CEM, LEED AP Green Building Program Manager, JCI Global Energy & Sustainability Services USGBC N. TX Chapter, Board Chair 2009

2 Environmental Impact of Buildings Americans spend as much as 90% of time indoors. Buildings: Consume almost 40% of all energy. Add 40% to atmospheric emissions. Use 68% of all electricity. Use 12% freshwater, 88% potable water. Up to 40% of municipal solid waste stream. Exploit significant amounts of land.

3 Characteristics of Green Buildings Optimal environmental and economic performance Increased efficiencies, saving energy and resources Satisfying, productive, quality indoor spaces Whole-building design, construction, and operation over entire life cycle Fully integrated approach teams, processes, systems

4 U.S. Green Building Council National coalition representing all sectors of the building industry. (Founded in 1993) Promotes design, construction, operation of environmentally responsible, profitable, healthy places to live and work. Launched Leadership in Energy and Environmental Design (LEED) in Rating system to guide sustainable project development for new construction.

5 U.S. Green Building Council Growth 18,400+ member companies, firms, government agencies or organizations 19,800+ Registered building projects 2,250+ Certified Buildings 81,000+ LEED APs 80 Local Chapters (3 in TX) Local Rep: Cindy Stanley, Executive Director USGBC N.

9 LEED Categories All Rating Systems Sustainable Sites Materials & Resources Water Efficiency Energy & Atmosphere Indoor Environmental Quality Innovation

10 LEED EB O&M: When to Use it Re-Certify a building that was LEED NC Certified previously (JCI Brengel Center) Certify Existing Whole Buildings (Not for individual tenant spaces or parts of existing buildings) Campuses can be Certified with EB O&M (Utility metering to individual building level is required for BTU/SF/Yr. assessment) Quantify the Sustainability of a building (Use LEED EB O&M as the M&V metric)

11 LEED EB O&M Minimum Project Requirements Building must be occupied for at least 12 months with 75% occupancy rate or greater per industry standards for building type 90%+ of the building SF must be included in LEED Certification (Up to 10% SF exclusion allowed but only for areas with separate use/management practices) Must meet all regulatory requirements for hazardous material management (PCB/Asbestos/Mercury in lamps) & waste water discharge Min. 3 month performance period required for all credits pursued (One year minimum for Energy)

19 Most Critical Step to Green Buildings EPA ENERGY STAR Portfolio Manager Program LEED EB O&M: Score of 69 for Prerequisite & 2 points minimum required by USGBC for Energy Performance (E&A credit 1) Score 1 point toward LEED Certification for every 2 points scored above 69 in ENERGY STAR Program (Up to 15 points possible) Energy Efficiency Retrofits (ES Score <69) ENERGY STAR Label (ES Score of 75+)

20 LEED EB Energy Performance Credit 1 Rank buildings with ENERGY STAR Portfolio Manager (Free EPA Tool) Is 20 MPG high or low for an automobile? Fuel Efficiency 5-60 MPG Is 80 kbtu/sf/yr high or low for a building? Energy Efficiency Score = 1-100

24 Innovation in Operations Credits 3 Credits Innovation in Operations Credits (4 max.) LEED Accredited Professional (LEED AP) Documenting Sustainable Building Cost Impacts 7 Points

25 LEED Innovation in Design Credits Intent To provide design teams and projects the opportunity to be awarded points for exceptional performance above requirements set by the LEED Green Building Rating System and/or Innovation in Green Building categories not specifically addressed by the LEED Green Building Rating System. Rules of Thumb: Exceed the maximum of any point criterion by the next increment (e.g. Perform to the next increment on the defined scale = Innovation credit) Double the maximum criterion (e.g. 100% reduction vs a 50% max. reduction = Innovation credit) Creativity unique to project = Innovation Credit
