A new building in Manhattan is being constructed to the borders of its property line. It has a native/adaptive vegetated roof of 25 000 SF on a previously developed site. The building footprint is 50 000 SF and has a FAR of 1.55 as well as 12 DU/acre. What credit would this project not be eligible for? LT Credit High Priority Site SS Credit Open Space LT Credit Surrounding Density and Diverse Uses SS Credit Site Development – Protect or Restore Habitat
Answer: LT Credit High Priority Site Explanation: Because the FAR is greater than 1.5 the vegetated roof will count towards open space. The project could earn the protect/restore credit because more than 30% of the previously developed site was restored and the density is greater or equal to 12. There is not enough info for High priority site.
27
Installing occupancy sensors would not impact which credit in a brand new mixed-use office building? EQ Credit Enhanced IAQ Strategies EA Prerequisite Minimum Energy Performance EQ Credit Thermal Comfort EQ Prerequisite, Minimum IAQ Performance
Answer: EQ Credit Enhanced IAQ Strategies Explanation: Occupancy sensors are not part of monitoring outdoor air delivery. Occupancy sensors can be integrated in the design to turn down the thermostat automatically and reduce airflow when occupants are away, helping to reduce energy use. Occupancy sensors will decrease/increase the temperature in the building which can change the indoor air quality. EQ Credit Enhanced IAQ Strategies requires individual comfort controls. Occupancy sensors are not a type of individual comfort control. They are used for groups or areas rather than the individual.
28
In a brand new school how much refrigerant is permitted in the form of CFCs? None 2% if it will be phased out 20% if it is a non-impact CFC 5% if it has a low refrigerant charge
Answer: None Explanation: There is no reason why a new building should use CFCs. This is not a major renovation so phasing it out is nonsense and the other options are incorrect.
29
Which option would be the best location for MERV rated filters? On all return ducts At each local distribution point On each of the 2 outdoor air systems On the diffusers and exhausts
Answer: On each of the 2 outdoor air systems Explanation: Filters must also be replaced after completion of construction and before occupancy. The other options would not benefit from filtration especially on exhausts. Why filter what is leaving?

34
How can a project count a transit stop that has service in both directions and is within ½ mile from 1 of 5 functional entries in a building? This is not eligible for the credit as not all functional entries are within ½ mile Both directions can be counted as separate towards the credit Only trips from one of multiple stops in the vicinity and only trips in one direction are counted A site served by 2 diverse means of transit which neither provide 60% of the total trips would count for extra points
Answer: Only trips from one of multiple stops in the vicinity and only trips in one direction are counted Explanation: This is the only correct answer that we have enough information for. Not all functional entries must be within walking distance. Although a site served by 2 diverse means of transit which neither provide 60% of the total trips would count for extra points. There is not enough information to confirm that this site is one of those.
35
A blackberry (RIP) project which PEMI consulted on in Waterloo Ontario was using a historic building that could not meet the 10 foot long mat requirement. Who must address this item? LEED technical customer service The project administrator A member of the technical advisory group GBCI certification reviewer The city councillor

Answer: 38 preferred parking spaces and 15 alternative fueling stations Explanation: For LT Credit Green Vehicles, 5% of parking must be preferred, and 2% of parking must have a fueling station. The two cannot be combined. Remember to round up.
48
A project team needs one more point to reach LEED Platinum and is exploring creating a new Innovation in design program for placing an interactive dashboard with building information in the lobby. What is true about this proposed credit? This would not be eligible since there is a prerequisite addressing recycling these items If all the batteries are recycled and the owner signs off on the agreement then this would work IN Credit Innovation can only be earned if all occupants of the building are allowed to participate in the program A LEED AP would have to sign off of this credit for it to count
Answer: IN Credit Innovation can only be earned if all occupants of the building are allowed to participate in the program Explanation: The three basic criteria for achieving an IN credit for a category not found in the LEED rating system are as follows: • Quantitative – this means the concept must have measurable/quantifiable environmental benefits. Establish a baseline and compare it with the final outcome to determine the improvement. How much environmental benefit did the strategy achieve? • Comprehensive – the process or specification must be comprehensive. For example, if a new material could be used in every floor of a building, the project team can’t use it in just one floor. A process that only addresses a part of the project isn’t considered comprehensive and does not meet the credit requirements. • Transferrable – the concept must be able to be used on other projects by other project teams. It can’t be a concept that only applies to a unique aspect of one project.
49
A development team is trying to find a site that is located near a bike network but wants your help to properly explain what it is? Streets with a maximum speed limit of 30 mph without dedicated bicycle stripes A continuous network of bike trails A separated bike lane on a graded road A bike path through a park
Answer: A continuous network of bike trails Explanation: This is the best description. Bicycle Network – a continuous network consisting of any combination of the following: • off-street bicycle paths or trails at least 8 feet (2.5 meters) wide for a two-way path and at least 5 feet (1.5 meters) wide for a one-way path • physically designated on-street bicycle lanes at least 5 feet (1.5 meters) wide • designed for a target speed of 25 mph (40 km/h) or less

For the WE Prerequisite Indoor Water Use Reduction, how would using an evaporative condenser that uses 100% potable water affect it? The team would need to blend the water with non-potable sources The team would need to add a meter for makeup water The team would need to increase the number of cycles of concentration The team would need to hire a water treatment professional to conduct a one-time potable water analysis
Answer: The team would need to add a meter for makeup water Explanation: The prerequisite requirements for cooling towers and evaporative condensers are to make sure the equipment has: • makeup water meters • conductivity controllers and overflow alarms • efficient drift eliminators
51
A building has a large surface level parking lot and they calculated the amount of runoff needed for the 95 percentile storm. In the credit for storm water runoff, how much of that 95 percentile must be managed? Only the runoff from the impervious areas of the site Only the runoff from the previously developed area 95% of the total site runoff 100% of total site runoff 25% of all impervious surfaces
Answer: 100% of total site runoff Explanation: The strategies used must manage 100% of the runoff volume for the entire developed site. 25% of all impervious surfaces is for an existing building.
52
