Question #2
What importance does the heat island effect have on mechanical systems and architectural design?
Water Efficiency
NEW
• 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
• 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
Question #3
Why is it important to distinguish between potable and non-potable water use?
Energy &Atmosphere
NEW
NEW
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
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
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%
Whole building monitoring of energy sources and
Monitoring of energy use 10% of building
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

Question #4
What is the biggest change in Energy & Atmosphere when compared to LEED 2009?
Materials &Resources
NEW
• 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.
Chico Gateway Museum: 114.72 tons generated = 229,440 pounds9,698 s.f. 23.68 psf generated! (68% diverted)
Fausel Professional Building: 158.24 tons generated = 316,480 pounds18,637 s.f. 16.98 psf generated! (82% diverted)
NRF Production Support Complex: 303.4 tons generated = 606,800 pounds89,964 s.f. 6.74 psf generated! (65.5% diverted)
