EA (Enegy And Atmosphere) Advanced 1 Flashcards
Which refrigerant has a LOW ozone depletion but HIGH global warming impact?
HCFCs
Which refrigerant has a HIGH ozone depletion?
CFCs
Where can a project team find information to determine the energy cost supplied by the renewable energy systems?
Optimize Energy Performance or the CBECS (Commercial Buildings Energy Consumption Survey) database
How many points does a net zero building earn for EA C, Green Power and Carbon Offsets?
2 points
-All other buildings must purchase a combination of green power and carbon offsets equal to 100% of the project’s energy
Which components are part of monitoring based commissioning?
- real time equipment performance
- permanent energy monitoring system
- ongoing commissioning
What is the minimum contract length for demand response enrollment?
1 year with the intent to renew for multiple years
What is the minimum contract length required for green power and carbon offsets?
5 years
To earn 3 points, a Core and Shell project must get what percentage of it’s buildings annual energy from on-site renewable energy?
5% of its COST, not total energy
What information should be included in commissioning plan?
A
How are coats for carbon offsets calculated?
Based on quantity of energy consumed which generates Scope 1 and Scope 2 emissions
When must the commissioning authority be engaged in order to meet EA P1, Fundamental Commissioning and Verification?
By the end of design development
How is the amount of green power purchased by the operating company calculated to determine what amount of power will qualify for the EA C, Green Power and Carbon Offsets?
Must purchase 50% renewable power for a 5 years.
Example 1: 254,000sf office requires 11.7kWh/sf/year
254,000 x 11.7 = 2,971,800 x 50% = 1,485,900 sf x 5 = 7,429,500 kWh
Define NON-REGULATED LOAD
Any building load, end use or control which does not have an ASHRAE 90.1-2010 baseline modeling requirement that allows the load and use or control to be modeled differently in the proposed and baseline buildings
What is the first step before attempting EA Pre, Minimum Energy Performance?
Determine the climate zone which then determines the mandatory requirements from ASHRAE.
Question 40
A
What is the unit of measure for green power?
MWh
At a minimum, what systems must be commissioned for fundamental commissioning?
- HVAC (Heating, ventilation, air conditioning)
- Lighting and daylighting controls
- Domestic hot water systems
- Renewable energy systems
What tool is used to help set energy use/efficiency goals?
ENERGY STAR Target Finder helps determine EUI (energy use intensity)
What is the trade off when using VRF (variable refrigerant flow) systems?
These systems improve energy efficiency but require higher refrigerant charges.
In an existing building, when must all CFC based equipment be phased out?
Before the project’s completion
What is the minimum requirement for energy reduction from the baseline to earn LEED certification?
5% reduction
In a new building, how much CFC based refrigerant can be used?
None
How many prerequisites are there for EA and what are they?
4 prerequisites
P1. Fundamental Commissioning and Verification
P2. Minimum Energy Performance
P3. Building Level Energy Metering
P4. Fundamental Refrigerant Management
How many credits for EA are there and what are they?
7 credits
C1. Enhanced Commissioning C2. Optimize Energy Performance C3. Advance Energy Metering C4. Demand Response C5. Renewable Energy Production C6. Enhanced Refrigerant Management C7. Green Power and Carbon Offsets
What additional steps by the CxA are required in order to earn points towards EA C1, Enhanced Commissioning?
- Review submittals
- Train operations team
- 10-month post occupancy visit
What is MBCx (monitoring based commissioning)?
Integration of three components:
- Permanent energy monitoring services
- real time energy analysis
- ongoing commissioning
