Energy and Atmosphere Flashcards
Core of EA
Energy demand
Energy efficiency
Renewable energy
Ongoing energy performance
EAp1 + EAc1 - Commissioning
Intent: ensure that the building owner gets desired/targeted performance out of energy efficiency systems
Process used to verify that the project’s energy-related systems were installed, calibrated and are performing according to the OPR, BOD and construction documents
EAp1 - Fundamental Commissioning and Verification
EAc1 - Enhanced Commissioning
EAp1 - Mandatory Commissioned Systems (MEP)
Mechanical - HVAC&R systems
Electrical - Lighting and day lighting controls
Plumbing - Domestic hot water systems
Renewable energy systems
EAc1 - Enhanced Commissioning
Path 1 (3 points)
- Review contractor submittals
- Verify inclusion of systems manual, occupant training reqs in construction docs and seasonal testing
- Review building operations 10 months after substantial completion
- Develop ongoing commissioning plan
Path 2 (4 pts)
Achieve Path 1 AND:
- Include procedures in commissioning plan
EAp2 + EAc2 - Energy Performance
Intent: establish energy performance baseline and encourage reduction of energy demand
3 Paths:
1. Whole Building Energy Simulation
Energy model of building compared to ASHRAE baseline model.
2. Prescriptive Compliance Path
ASHRAE 50% advanced energy design guide
3. Prescriptive Compliance Path
Advanced buildings core performance guide
Energy efficiency strategies
- Passive design and thermal energy storage
- High performance building envelope
- High performance building systems
- Verify and monitor performance
EAp3 + EAc3 - Energy Metering
Prereq: requires permanently installed meters which can aggregately provide total building energy consumption which can be compiled into monthly/annual summaries and shared with USGBC for 5 years
Credit: requires more advanced system for all individual energy end uses that represent 10% or more of total annual consumption. They must:
- Record at hour intervals
- Record demand and consumption
- Transmit data to remote location
EAp4 + EAc6 - Refrigerant Management
Intent: reduce global warming and ozone damage
Refrigerants w/low ODP tend to have high GWP
Requires zero use of CFC-based refrigerants in new buildings.
Enhanced credit: requires ODP + GWP under a specified value
EAc4 - Demand Response
Owners must agree to participate in DR program for 10%+ of estimated peak electricity demand
EAc5 - Renewable Energy Production
Wind Solar thermal, active and passive Photovoltaic Wave and tidal energy Biofuels Geothermal heating Low impact hydroelectric
EAc7 - Green Power and Carbon Offsets
Project must purchase 35% of building’s electricity consumption from renewable sources for at least 2 years
