  12. Location & Transportation

  13. v4 v2009 DIDN’T EXIST LTc1 • NEW CREDIT • ENCOURAGES EARLY ANALYSIS OF ENERGY AND WATER SYSTEMS TO INFORM DESIGN

  14. v4 LTC5 v2009 SSc4.1 • CREDIT RENAMED FROM “ALTERNATIVE TRANSPORTATION – PUBLIC TRANSPORTATION ACCESS” • MULTIPLE THRESHOLDS TO REWARD VARYING TRANSIT SERVICE LEVELS .25mi WALKABLE DISTANCE = .25mi RADIUS = .25mi

  15. v4 LTc8 v2009 Sc4.3

  16. Sustainable Sites

  17. NEW RENAMED / REORGANIZED

  18. v2009 DIDN’T EXIST v4 SSc1 • NEW CREDIT • ENCOURAGES EARLY ANALYSIS OF SITE CONDITIONS TO INFORM DESIGN

  19. v2009 SSc7.1 v4 SSc4 v2009 SSc7.2 • COMBINATION OF “HEAT ISLAND EFFECT – NONROOF” AND “HEAT ISLAND EFFECT – ROOF” • UPDATED

  20. SACRAMENTO

  21. v2009 SSc8 v4 SSc6 • INCLUDED THE BUG RATING METHODOLOGY AS A PRESCRIPTIVE WAY TO MEET THE EXTERIOR LIGHTING REQUIREMENTS • ADDED LIGHTING ZONE 0 • INCLUDED EXTERIOR SIGNAGE REQUIREMENTS • ADDED EXEMPTIONS

  22. Question #2 • What importance does the heat island effect have on mechanical systems and architectural design?

  23. Water Efficiency

  24. NEW

  25. No irrigation beyond 2-yr. maximum establishment period, OR • 30% minimum irrigation water reduction for peak watering month. • Building Water Use • 20% minimum indoor water reduction. • New fixtures: Watersense labeled • Appliance and Process Water Use • Standards for Appliances – ENERGY STAR, CEE • Standards for Processes: • No once-through potable water cooling for appliances that reject heat • Cooling Towers and Evap. Condensers: Equip with additional meters and alarms to reduce water use • Permanent water meters for potable water – manual or automated • Share 5 years of data with USGBC

  26. Conduct a one-time potable water analysis in cooling towers and evaporative condensers to measure concentrations of 4 minerals + conductivity • 1 point: Limit cooling tower cycles to avoid exceeding maximum concentration levels. • +1 point: Increase treatment OR use 20% recycled non-potable water • Permanent Water Meters for Two or More Subsystems: • Irrigation • Indoor plumbing fixtures • Domestic hot water • Large boilers • Reclaimed water • Other process water

  27. Question #3 • Why is it important to distinguish between potable and non-potable water use?

  28. Energy & Atmosphere

  29. NEW NEW

  30. Reference Guides: • ASHRAE Guidance 0-2005 and ASHRAE Guideline 1.1-2007 for HVAC&R Systems • NIBS Guideline 3-2006 for exterior closures • Addition of exterior closures in OPR and BOD documents • Can be reviewed by member of design or construction team • Creation of Facilities Maintenance Plan

  31. ASHRAE 90.1-2010 • More efficient Baseline • Must meet before counting Renewable Energy • Option 1: Energy Simulation • 5% NC, 3% MR, 2% CS • Retail must include process load equipment • Option 2: Prescriptive Compliance: ASHRAE 50% Energy Design Guide • Option 3: Prescriptive Compliance: Advanced Buildings’ “Core Performance” Guide • Less then 100,000 SF • Not Healthcare • Data Centers must be 5% over baseline by energy cost and IT equipment cost • Includes cooling units for computer and data rooms and critical equipment • 2% of 5% energy savings through building power cooling infrastructure • Include process loads from unregulated load and IT equipment load

  32. Meters for five years • Share with USGBC • Path 1: is similar to LEED 2009 • Path 2: Additional point by developing monitoring-based procedures and identify measurement points to evaluate performance of systems AND/ OR (2pts) • Option 2: Envelope Commissioning • Data Centers that select Path 2 Option 1 must: • Review of OPR and BOD before 50% CD’s • Back check review comments and • Review at 95% • Larger projects review at start of DD’s, before 50% CDs, and at 100%

  33. Makes energy generation more efficient, grid reliability, reduces greenhouse gasses • Participate in DR program w real time fully automated if Initiated by external DR programmer • 1 yr 10% peak energy demand • Plan for meeting commitment and scope of work for Cx to test system OR if DR not available (1pt) • Install infrastructure for future program • Plans for commitment and Cx • Contact utility about future participation • Whole building monitoring of energy sources and • Monitoring of energy use 10% of building

  34. Addition of carbon offsets for scope or 2 emissions on a metric ton of carbon dioxide Green-e Climate or equivalent certified • Must be for offsets for projects within US • 50% and 100% reduction

  35. Question #4 • What is the biggest change in Energy & Atmosphere when compared to LEED 2009?

  36. Materials & Resources

  37. NEW

  38. New: • Now can Include wood waste converted to fuel (bio-fuel) in the calculations • Waste-to-energy systems may be considered waste diversion if listed directives are followed • Option 1: Divert 50% and three material streams (1 point) • Option 2: Divert 75% and four material streams (2 points) • Option 3: Reduction of total waste material (2 points) • Do not generate more than 2.5 pounds of construction waste per square foot of the building's floor area.
