Intent:
Provide for the ongoing accountability of building energy consumption over time. Basically, develop a plan to measure and check the building's energy consumption.
Implementation:
sidenote: there are 4 options, but for LEED we only look at 2, B and D.
Develop and implement a Measurement and Verification (M&V) Plan consistent with:
OPTION B (smaller ...

Intent:
Reduce ozone depletion potential (ODP) and global warming potential (GWP)
Support early compliance with EPA Montreal Protocol
Implmentation:
Quick Information:
refrigerant comparison
CFC (high)
HCFC (medium)
HFC (low)
efficiency of HFC is less than HCFC
OPTION 1: do not use ANY refrigerants
OPTION 2: use refrigerants and HVAC that minimizes or eliminates emission of compounds that cause ozone depletion & ...

Intent:
To begin commissioning process early during design process
Execute additional activities after systems performance verification is completed
Implementation:
In addition to prerequisite commissioning (EAp1):
designate CxA (commissioning authority) to lead/review/oversee completion of all commissioning process activities
CxA must REVIEW OPR (Owner's Project's Requirements), BOD (Basis of Design), and Design Documents prior to 50% CD.
CxA shall ...

Intent:
Reduce ozone depletion.
Implementation:
New Building: Zero use of CFC-based refrigerants in HVAC systems
Existing Building: Consider replacement or "phase-out" program for HVAC units and fire systems with CFCs.
CFC production stopped in 1995 and was phased out 5 years after that.
Existing mechanical systems connected to existing chilled water systems have to be CFC-free.
notes:
ODP: ...

option 1:
Building envelope and system to comply with ASHRAE / IESNA 90.1-2004 Sections 5 - 10
Comply with prescriptive requirements of ASHRAE, 90.1-2004
option 2:
comply with local codes or DOE (Department of Energy), instead of ASHRAE
mandatory: provide occupancy controls for:
class rooms
meeting rooms
break rooms
Code:
ASHRAE ...
