Which of the following Sustainable Sites credits are eligible to be used as a campus approach?
Correct Answer: D
According to the LEED Campus Guidance, the campus approach allows projects that share a single location and site attributes to achieve separate LEED certification for each project, building space, or group on the master site. The campus approach can be used for certain credits that are influenced by the site conditions and infrastructure, such as Sustainable Sites credits. The LEED Campus Guidance provides a list of eligible credits for the campus approach, which includes the following Sustainable Sites credits1: *Site Assessment *Site Development - Protect or Restore Habitat *Open Space *Rainwater Management *Heat Island Reduction *Light Pollution Reduction Therefore, Heat Island Reduction, Light Pollution Reduction, and Rainwater Management are Sustainable Sites credits that are eligible to be used as a campus approach. Places of Respite, Site Master Plan, and Direct Exterior Access are not Sustainable Sites credits, but other credits or prerequisites that are not eligible for the campus approach1.

Question 67
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?
Correct Answer: C
Explanation 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 spaces1. * 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 preferences2. 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.

Question 68
The contractor has submitted waste hauling reports for review in order to achieve Materials and Resources Credit, Construction and Demolition Waste Management. Which of the following materials on the documentation contribute towards the credit?
Correct Answer: B
This option requires the project to classify wood derived fuel as a recycled material that contributes towards the credit, because it is a waste material that is converted into a useful energy source1. Wood derived fuel can be used for heating, electricity generation, or co-firing with other fuels2. According to the LEED v4: Building Design + Construction Guide, recycled materials are those that have been reprocessed or remanufactured from recovered materials3.
Question 69
Which of the following project types is required to consider the perimeter floor area instead of the regularly occupied floor area under the Indoor Environmental Quality Credit, Daylight calculations?
Correct Answer: C
Explanation Healthcare projects are required to consider the perimeter floor area instead of the regularly occupied floor area under the Indoor Environmental Quality Credit, Daylight calculations. This is because healthcare projects have different daylighting needs and challenges than other project types, and the perimeter area is more likely to have access to natural light and views. The perimeter floor area is defined as the regularly occupied spaces within 15 feet (4.5 meters) of the exterior wall that meets the minimum glazing requirements.

Question 70
A contractor is building a retirement community project. 30% of the building's product costs were derived from reused/salvaged materials or met recycled content criteria. Which of the following credits can the LEED AP submit towards certification?
Correct Answer: A
Explanation The Materials and Resources Credit, Building Product Disclosure and Optimization - Sourcing of Raw Materials rewards projects that use materials that have optimized extraction processes by limiting or eliminating the extraction of new resources, the reuse of materials or the use of recycled materials1. According to the LEED Reference Guide for Building Design and Construction2, the credit has two options: Option 1. Raw Material Source and Extraction Reporting and Option 2. Leadership Extraction Practices. Option 1 requires the project to use at least 20 permanently installed products from at least five different manufacturers that have publicly released a report from their raw material suppliers which include extraction locations, a commitment to long-term ecologically responsible land use, a commitment to reducing environmental harms from extraction and/or manufacturing processes, and a commitment to meeting applicable standards or programs voluntarily that address responsible sourcing criteria2. Option 2 requires the project to use products that meet at least one of the responsible sourcing criteria below for at least 25%, by cost, of the total value of permanently installed building products in the project: * Extended producer responsibility. Products purchased from a manufacturer (producer) that participates in an extended producer responsibility program or is directly responsible for extended producer responsibility. * Bio-based materials. Bio-based products must meet the Sustainable Agriculture Network's Sustainable Agriculture Standard. Bio-based raw materials must be tested using ASTM Test Method D6866 and be legally harvested, as defined by the exporting and receiving country. Exclude hide products, such as leather and other animal skin material. * Wood products. Wood products must be certified by the Forest Stewardship Council or USGBC-approved equivalent. * Materials reuse. Reused products must include salvaged, refurbished, or reused products. * Recycled content. Recycled content is the sum of postconsumer recycled content plus one-half the preconsumer recycled content, based on cost. Products meeting recycled content criteria are valued at 100% of their cost for the purposes of credit achievement calculation. * USGBC approved program. Other USGBC approved programs meeting leadership extraction criteria. Therefore, among the given options, only Option A is relevant to the use of reused/salvaged materials or recycled content, as they can contribute to the materials reuse or recycled content criteria under Option 2. Option B is a prerequisite that requires the project to develop and implement a construction and demolition waste management plan that identifies the materials to be diverted from disposal and whether the materials will be sorted on-site or co-mingled2. Option C is a credit that requires the project to use at least 20 different permanently installed products from at least five different manufacturers that use any of the following programs to demonstrate the chemical inventory of the product to at least 0.1% (1000 ppm): * Health Product Declaration. The end use product has a published, complete Health Product Declaration with full disclosure of known hazards in compliance with the Health Product Declaration Open Standard. * Cradle to Cradle. The end use product has been certified at the Cradle to Cradle v2 Basic level or Cradle to Cradle v3 Bronze level. * REACH Optimization. The end use product is compliant with REACH Optimization criteria. * GreenScreen v1.2 Benchmark. The product's chemical ingredients are inventoried using the GreenScreen v1.2 Benchmark. * Declare. The Declare product label must indicate that all ingredients have been disclosed down to 1000 ppm. Option D is a credit that requires the project to use at least 20 different permanently installed products that have environmental product declarations. The products must be sourced from at least five different manufacturers. The environmental product declarations must conform to ISO 14025, 14040, 14044, and EN 15804 or ISO 21930 and have at least a cradle-to-gate scope2.
