A. Building loads i. Design (e.g., building orientation; glazing selection; clarify regional considerations) ii. Space usage (e.g., space types [private office, individual space, shared multi- occupant spaces]; equipment and systems) iii. Opportunities for passive design
B. Energy efficiency i. Assemblies/components (e.g., building envelope; HVAC; windows; insulation) ii. Operational energy efficiency (e.g., schedules; set points; interactions between systems) iii. Commissioning (e.g., commissioning authority (CxA); owner’s project requirements (OPR); basis of design (BOD); monitoring-based commissioning; envelope commissioning)
C. Demand response (e.g., grid efficiency and reliability; demand response programs; load shifting)
D. Alternative and renewable energy (e.g., on-site and off-site renewable energy; photovoltaic; solar thermal; wind; low-impact hydroelectricity; wave and tidal energy; green power, carbon offsets)
E. Energy performance management
- Advanced energy metering (e.g., energy use measurement; building automation controls)
- Operations and management (e.g., training of staff; operations and maintenance plan)
- Benchmarking (e.g., metrics used; proposed building performance rating/ baseline building performance rating; comparing building energy performance against similar buildings or historical data; tools and standards [ASHRAE, CBECS, Portfolio Manager])
F. Environmental concerns: resource and ozone depletion (e.g., sources and energy resources [oil, coal and natural gas]; renewable and nonrenewable resources; chlorofluorocarbons [CFCs] and other refrigerants; stratospheric ozone layer)
G. Energy model as a tool
H. Process loads (e.g., elevator; refrigeration, etc.)
I. Iterative optimization
