An office building has six individual workstations, two private offices, and a
conference room. What lighting control configuration would meet the
requirements of EQ Credit Interior Lighting?
Individual lighting controls for four workstations and multizone control for the conference
room.
There are 8 individual occupant spaces, so any combination that equals 50% of the
individual spaces would count as meeting the requirements.
When occupancy data is entered into the indoor water use calculator, it is split by
default to a 50/50 gender ratio. Under which circumstance should this be ratio
changed?
A project can alter the default ratio if it is justified. Same-sex schools are one example.
What frequency of recording data is required during the performance period for
WE Credit Water Metering?
All meters, including whole-building meter, must be recorded at least weekly and used
in a regular analysis of time trends

Project teams should coordinate the solid waste management policy and the
environmentally preferred purchasing policy in what areas?
Areas such as source reduction, contract agreements, communications with building
occupants overlap between the two policies.
A project team is inventorying the regularly occupied spaces of an office building
occupied by one tenant. Under what circumstances could any of the regular
occupied spaces be excluded from the requirements of daylighting?
When tasks would be hindered by the use of daylight
This is the only exception allowed.
A project team is reviewing a project's goals. What type of analysis would be
appropriate for existing building commissioning?
The focus is on proper system operations
The Existing Building Commissioning option focuses more on controls, proper system
operations and efficiency improvements.
The other choices would benefit from an ASHRAE Level 2 Energy Survey and Analysis.
The classification of a sink in a mixed-use project is unclear. Which action should
the LEED AP take when performing the indoor water-use calculations?
Classify the sink as public
If the classification for public or private use is unclear, default to public use flow rates
when performing the calculations
A school project is located in an area the does not provide composting services.
What can the project team do during the performance period to earn MR Credit
Solid Waste Management - Ongoing?
Implement an awareness program that encourages occupants to reduce food waste
An education program has to be in place for the credit during the performance period
The WaterSense Water Budget tool uses which variables to determine how much
water a project needs?
Each location's rainfall .
Evapotranspiration levels .
The tool uses the location's ZIP code to estimate the evapotranspiration rate for the
peak watering month. The tool uses historical data to determine rainfall. This
information, along with the landscape area entered, is used to determine a landscape
water allowance.
,A project building has a total 100 regular building occupants and visitors. What
minimum response rate is needed for a valid transportation survey?
5 total regular building occupants and visitors
The minimum response rate needed overall accounting for both regular occupants and
transient occupants is 5% and extrapolations of results can begin at 30%.
A project team analyzed the survey results for regular occupants to calculate the
alternative transportation rate and found only a 25% survey response rate. What
should the project team do next?
Assume nonrespondents are commuting via single-occupancy vehicles
Anything less than a 30% response rate isn't allowed to be extrapolated.
An office building with multiple tenants has one tenant undergoing a renovation
during the performance period. What is the minimum scope of work required for
products and materials to be eligible for MR Credit Purchasing - Facility
Maintenance and Renovation?
There is no minimum scope of work required
The credit requires no minimum scope of renovation or new construction work
Show Answer Legend
A demand response sequence is acceptable for LEED except when:
A utility company sends a DR event via e-mail, and a person on-site manually adjusts
thermostats.
What needs to be performed in an ASHRAE energy use analysis?
Determine the approximate energy use breakdown for major end-use categories
The analysis is used to prepare for the audit. The energy analysis includes all fuel
sources.
How would a project team determine the peak and off-peak hours as they apply to
Demand Response?
By contacting the utilities serving the project site
The utility company sets the peak and off-peak hours
A project's total site area is 280,000 SF (26,000 m2). A landscape architect has
categorized all areas of a site as either greenfield (180,000 SF/16,700 m2) or
developed (100,000 SF/9,290 m2). Which strategy could the project team use to
earn SS Credit Site Development - Protect or Restore Habitat?
Protect or restore 56,000 SF (5,202 m2) of the total site area.
For the credit remember:
Restore 20% (including building footprint) of the total site area (including the building
footprint).
OR
Provide financial support (donated land does not count).
Restore 280,000 X 20% = 56,000
What statement is true regarding the inclusion of lamps in the calculations for MR
Credit Purchasing - Lamps?
Mercury-free LEDs can be included if they have high enough energy efficiency levels

What is a best practice for the handling of mercury-containing lamps?
Ensure that employees charged with handling the mercury-containing lamps are
adequately trained or use outside experts as contractors to do this work.
Which manufacturer data, if present, would a project team use to best determine
the heat island mitigation of a device used to shade cars in a parking lot?
Three-year aged SR value.
The three-year aged SR value if available is the best attribute for comparing products
What best describes the performance period?
The continuous implementation of the strategies set during the establishment period
For SS Credit Site Management how frequently must an irrigation system be
checked during the operating season for leaks, breaks, irregularities in water
usage, and system time settings?
Check the system at least every two weeks.
Which team member will ultimately be responsible for approving the facility
maintenance and renovation policy?
Building owner or property manager
The maintenance plan for ventilation systems during the performance period is
typically satisfied by:
The preventative maintenance plan required for EA Prerequisite Energy Efficiency Best

A $50 plastic chair contains 10% post-consumer recycled content by weight.
What value of the product contributes to credit achievement of MR Credit
Purchasing - Facility Maintenance and Renovation?
$5 .
Most products are weighted at 100% of cost. Some may be higher or lower (Extended
producer responsibility is lower - 50%, Cradle to Cradle v2 Platinum is higher - 150%).
For material assemblies or furniture, the percentage of the product that is compliant by
weight determines the percentage of the product cost that contributes towards the
credit.
If a product contains 10% post-consumer recycled material by weight, 10% of the
product cost contributes to the credit achievement.
A project team wants to include occupancy sensors to turn-off the lights when
the occupants have left a space. What multi-occupant spaces would benefit from
having the sensors installed?
Meeting rooms.
Further, pay attention to the differences between regularly occupied spaces and
nonregularly occupied spaces.
The question asks about multi-occupant spaces.
