How many points are possible from EA Credit 2 NC?
|
7
|
|
|
What percentage of renewable energy is required for 7 points?
|
13%
|
|
|
What is the intent of EA Credit 2?
|
To encourage and recognize increasing levels of on-site renewable energy self-supply to reduce the environmental and economic impacts associated with fossil fuels
|
|
|
What is required of EA Credit 2 ON-SITE RENEWABLE ENERGY
|
Use on-site renewable energy to offset building energy cost.
|
|
|
Project performance is calculated as a percentage of what?
|
renewable systems as a percentage of the buildings annual energy cost
|
|
|
The base of the percentage of renewable energy come from?
|
EA CREDIT 1: Optimize Energy Performance or
DOE Commercial Buildings Energy Consumption Survey database |
|
|
What are benefits of On Site Renewable Energy?
|
Using renewable energy instead of fossil fuels can:
a. Dramatically improve outdoor environmental quality. b. Reduce air and water pollution c. Enhance economic development especially in rural communities. |
|
|
What are some ways to offset initial cost of On Site Renewable Energy?
|
A. Future savings
B. Net Metering C. Utility Rebates |
|
|
What other credits are required by On Site Renewable Energy
|
Commisioning and Measurement and Verification
|
|
|
What are credits that have synergies with On Site Renewable Energy?
|
EA PreReq 1: Fundemental Commisioning
EA PreReq 2: Minimum Energy Performance EA Credit 1: Optimize Energy Performance EA Credit 5: Measurement and Verification EA Credit 6: Green Power |
|
|
Explain a synergy between On Site Renewable Energy and purchasing green power.
|
On-site energy generation reduces the quantity of green power that must be purchased to offset the builidings energy use.
|
|
|
On-site renewable energy is or is not included in the design cost of the performance rating method of ASHREA 90.1?
|
On site renewable energy is considered free and not included in the design cost.
|
|
|
What types of energy are considered renewable?
|
Solar, Wind, Geothermal, Water, Bio-based, to satisfy electric power demand or directly offset space heating, space cooling, or water heating energy consumption
|
|
|
Does on-site renewable energy that produced but not consumed or sent back to the grid count toward the credit calculation?
|
No. Energy produce on-site that is not captured and used, whether or via the grid, cannot be included in the credit calculation.
|
|
|
Can stored On-site renewable energy be used in the credit calculation?
|
Yes, if it is eventually used or sent back to the grid.
|
|
|
Is renewable energy produced on-site and then sold to the grid eligible for the On-site renewable energy calculation?
|
No.
|
|
|
Name the eligible On-Site Systems.
|
Photovoltaic Systems
Wind Energy Systems Solar Thermal Systems Biofuel-based electrical systems Geothermal Heating Systems Geothermal Electrical Systems Low-impact hydroelectric power systems Wave and Tidal power systems |
|
|
What are eligible biofuels for On-site renewable energy systems?
|
a. Untreated wood waste
b. Agricultural Crops or Waste c. Animal waste and other oganic waste d. Landfill gas |
|
|
What are ineligible On-Site energy systems?
|
a. Architectural features
b. Passive Solar c. Daylighting d. Geo-exchange systems (ground source heat pumps) |
|
|
What credit are Geo-exchange systems (ground source heat pumps) part of?
|
EA Prerequisite 2: Minimum Energy Performance and EA Credit 1: Optimize Energy Performance
|
|
|
What are ineligible biofuels for On-Site Renewable Energy?
|
a. Combustion of Solid Waste
b. Forestry biomass other than mill residue c. Wood coated with paint, plastics, or formica. d. Wood treated for preservation. 1% of perservative makes the fuel ineligible. |
|
|
Can you sell back On-Site renewable energy at a premium?
|
No
|
|
|
REC are what?
|
REC are Renewable Energy Credits.
|
|
|
Can exemplary performance be obtained?
|
Yes, by showing that on-site renewable energy accounts for 15% or more of the annual building cost.
|
|
|
Where is energy efficiency crucial?
|
In regions where coal is used to generate electricity.
|
|
|
What should be done to measure the energy production over the life of the system?
|
Sub-metering
