EA (Enegy And Atmosphere) Advanced 1

Question 1

Which refrigerant has a LOW ozone depletion but HIGH global warming impact?

Answer 1

HCFCs

Question 2

Which refrigerant has a HIGH ozone depletion?

Answer 2

CFCs

Question 3

Where can a project team find information to determine the energy cost supplied by the renewable energy systems?

Answer 3

Optimize Energy Performance or the CBECS (Commercial Buildings Energy Consumption Survey) database

Question 4

How many points does a net zero building earn for EA C, Green Power and Carbon Offsets?

Answer 4

2 points

-All other buildings must purchase a combination of green power and carbon offsets equal to 100% of the project’s energy

Question 5

Which components are part of monitoring based commissioning?

Answer 5

• real time equipment performance
• permanent energy monitoring system
• ongoing commissioning

Question 6

What is the minimum contract length for demand response enrollment?

Answer 6

1 year with the intent to renew for multiple years

Question 7

What is the minimum contract length required for green power and carbon offsets?

Answer 7

5 years

Question 8

To earn 3 points, a Core and Shell project must get what percentage of it’s buildings annual energy from on-site renewable energy?

Answer 8

5% of its COST, not total energy

Question 9

What information should be included in commissioning plan?

Answer 9

A

Question 10

How are coats for carbon offsets calculated?

Answer 10

Based on quantity of energy consumed which generates Scope 1 and Scope 2 emissions

Question 11

When must the commissioning authority be engaged in order to meet EA P1, Fundamental Commissioning and Verification?

Answer 11

By the end of design development

Question 12

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?

Answer 12

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

Question 13

Define NON-REGULATED LOAD

Answer 13

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

Question 14

What is the first step before attempting EA Pre, Minimum Energy Performance?

Answer 14

Determine the climate zone which then determines the mandatory requirements from ASHRAE.

Question 15

Question 40

Answer 15

A

Question 16

What is the unit of measure for green power?

Answer 16

MWh

Question 17

At a minimum, what systems must be commissioned for fundamental commissioning?

Answer 17

• HVAC (Heating, ventilation, air conditioning)
• Lighting and daylighting controls
• Domestic hot water systems
• Renewable energy systems

Question 18

What tool is used to help set energy use/efficiency goals?

Answer 18

ENERGY STAR Target Finder helps determine EUI (energy use intensity)

Question 19

What is the trade off when using VRF (variable refrigerant flow) systems?

Answer 19

These systems improve energy efficiency but require higher refrigerant charges.

Question 20

In an existing building, when must all CFC based equipment be phased out?

Answer 20

Before the project’s completion

Question 21

What is the minimum requirement for energy reduction from the baseline to earn LEED certification?

Answer 21

5% reduction

Question 22

In a new building, how much CFC based refrigerant can be used?

Answer 22

None

Question 23

How many prerequisites are there for EA and what are they?

Answer 23

4 prerequisites

P1. Fundamental Commissioning and Verification
P2. Minimum Energy Performance
P3. Building Level Energy Metering
P4. Fundamental Refrigerant Management

Question 24

How many credits for EA are there and what are they?

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

Question 25

What additional steps by the CxA are required in order to earn points towards EA C1, Enhanced Commissioning?

Answer 25

• Review submittals
• Train operations team
• 10-month post occupancy visit

Question 26

What is MBCx (monitoring based commissioning)?

Answer 26

Integration of three components:

• Permanent energy monitoring services
• real time energy analysis
• ongoing commissioning
