Which would contribute to compliance with Sustainable Sites Credit, Open Space?
Answer(s): D
According to the LEED v4: Building Design + Construction Guide, the Sustainable Sites Credit, Open Space requires the project to provide outdoor space greater than or equal to 30% of the total site area (including building footprint). At least 25% of that outdoor space must be vegetated, have overhead vegetated canopy, or be a water body. Option A does not qualify as outdoor space, Option B is not vegetated or a water body, and Option C only applies to projects with a FAR of less than 1.0. Option D meets the requirements for both outdoor space and vegetation, and also contributes to the protection or restoration of habitat.

A commercial new construction project consists of mixed space usage. When deciding which LEED rating system to use, the LEED AP should follow which of the following rules?
According to the LEED v4: Building Design + Construction Guide, the 40/60 rule provides guidance for making a decision when several rating systems appear to be appropriate for a project. To use this rule, first assign a rating system to each square foot or square meter of the building, and then choose the most appropriate rating system based on the resulting percentages. The entire gross floor area of a LEED project must be certified under a single rating system and is subject to all prerequisites and attempted credits in that rating system, regardless of mixed construction or space usage type. If a rating system is appropriate for less than 40% of the gross floor area of a LEED project building or space, then that rating system should not be used. If a rating system is appropriate for more than 60% of the gross floor area of a LEED project building or space, then that rating system should be used. If an appropriate rating system falls between 40% and 60% of the gross floor area, project teams must independently assess their situation and decide which rating system is most applicable.

What is the maximum number of points a project pursuing LEED for New Construction can achieve under Location and Transportation Credit, Access to Quality Transit?
Answer(s): C
According to the LEED v4: Building Design + Construction Guide, the Location and Transportation Credit, Access to Quality Transit has two options: Option 1. Transit-Served Location and Option 2. Transit Service Quality. Option 1 can earn 1 to 4 points depending on the percentage of functional entries within walking distance of transit stops or stations. Option 2 can earn 1 point if the project meets the minimum weekday and weekend headways for bus, streetcar, or informal transit stops, or rail stations or ferry terminals. The maximum number of points a project can achieve under this credit is 4 points by meeting both options.

If a commercial building is considered to have 100 peak visitors in a day, what is the minimum number of short-term bicycle storage spaces that must be provided to earn one point under Location and Transportation Credit, BicycleFacilities?
According to the LEED v4: Building Design + Construction Guide, the Location and Transportation Credit, Bicycle Facilities has two options: Option 1. Bicycle Network and Storage and Option 2.Reduced Parking Footprint. Option 1 requires the project to provide short-term bicycle storage for at least 2.5% of all peak visitors, and long-term bicycle storage for at least 5% of all regular building occupants. Short-term bicycle storage must be within 100 ft (30 m) walking distance of any main entrance, and long-term bicycle storage must be within 300 ft (90 m) walking or bicycling distance of any functional entry. Option 2 requires the project to provide short-term bicycle storage for at least 2.5% of all peak visitors, and long-term bicycle storage for at least 5% of all regular building occupants, and also reduce the total parking capacity by at least 20% from the base ratios. Both options can earn one point under this credit.If a commercial building is considered to have 100 peak visitors in a day, the minimum number of short-term bicycle storage spaces that must be provided to earn one point under Option 1 or Option 2 is 2.5% of 100, which is 2.5, rounded up to 3. However, the project must also provide long-term bicycle storage for at least 5% of all regular building occupants, which is not given in the question. Therefore, the correct answer is C, five, which is the minimum number of short-term bicycle storage spaces that must be provided to earn one point under Option 1 or Option 2, regardless of the number of regular building occupants.

Which of the following groups of documents is most likely to support both Indoor Environmental Quality Credit, Thermal Comfort, and Indoor Environmental Quality Credit, Interior Lighting, Option 1. Lighting Control?
The most likely group of documents to support both Indoor Environmental Quality Credit, Thermal Comfort, and Indoor Environmental Quality Credit, Interior Lighting, Option 1. Lighting Control is C, lighting plans, surveys of occupants, sequence of operations.Lighting plans show the layout and type of lighting fixtures, as well as the lighting controls, such as dimmers, timers, occupancy sensors, or daylight sensors. Surveys of occupants provide feedback on the satisfaction and comfort level of the building users regarding the thermal and lighting conditions. Sequence of operations describes how the mechanical and lighting systems operate and respond to different scenarios, such as occupancy, temperature, or daylight levels. These documents can demonstrate that the project meets the requirements for both credits, which are:For Thermal Comfort, the project must design the HVAC systems and the building envelope to meet the requirements of ASHRAE Standard 55-2010, Thermal Environmental Conditions for Human Occupancy, or a local equivalent, and provide individual thermal comfort controls for at least 50% of the individual occupant spaces, and group thermal comfort controls for all shared multi-occupant spaces.For Interior Lighting, Option 1. Lighting Control, the project must provide individual lighting controls that enable adjustments to suit individual task needs for at least 90% of the individual occupant spaces, and provide lighting system controls for all shared multi-occupant spaces that allow occupants to adjust the lighting to meet group needs and preferences. The other groups of documents are less likely to support both credits, because:Architectural floor plans, mechanical plans, and lamp specifications do not show the lighting controls or the occupant feedback.Photometric plans, mechanical schedules, and lamp specifications do not show the thermal comfort design or the occupant feedback.Surveys of occupants, photometric plans, and mechanical schedules do not show the lighting controls or the thermal comfort design.
