Which of the following buildings meets the Minimum Program Requirements for LEED certification?
Answer(s): D
The Minimum Program Requirements (MPRs) for LEED certification are:MPR 1: Must be in a permanent location on existing land MPR 2: Must use reasonable LEED boundariesMPR 3: Must comply with project size requirementsOption A does not meet MPR 1 because it is located on a previously undeveloped site, which is not considered existing land. Option B does not meet MPR 3 because it is a parking garage, which is excluded from LEED certification unless it is part of a larger project. Option C does not meet MPR 1 because it is a mobile clinic, which is not considered permanent. Option D meets all the MPRs because it is a permanent building on existing land, it has reasonable LEED boundaries, and it meets the minimum gross floor area of 1,000 ft2 (93 m2) for BD+C projects.

Which of the following would be most useful to a school project that is attempting to pursue Water Efficiency Credit, Indoor Water Use Reduction?
The Water Efficiency Credit, Indoor Water Use Reduction aims to reduce indoor water consumption by installing water-efficient fixtures and fittings, such as faucets, showerheads, toilets, and urinals. A commercial dishwasher that is ENERGY STAR® labeled or performance equivalent would help reduce the water use for dishwashing, which is one of the process water uses included in the credit calculation. A standard garbage disposal would not reduce water use, but rather increase it. An electronic submeter at the domestic water supply pipe to the building would help measure and monitor water use, but not directly reduce it. An open-loop HVAC system that discharges potable cooling water to a nearby lake would waste a lot of water and potentially harm the environment.

A project has total waste of 20 tons (18.1 tonnes) that includes the following:· 8 tons (7.3 tonnes) of recycled demolition steel and concrete · 2 tons (1.8 tonnes) of trees cleared from the site. 3 tons (2.7 tonnes) of commingled scrap with 40% diverted . 6 tons (5.4 tonnes) of used furniture donated to a non-profit organization · 1 ton (0.9 tonnes) of removed carpet and ceiling tiles sent back to the manufacturerWhat is the percentage of diverted waste for Materials and Resources Credit, Construction and Demolition WasteManagement?
Answer(s): B
The percentage of diverted waste for Materials and Resources Credit, Construction and Demolition Waste Management is calculated by dividing the total weight of diverted materials by the total weight of waste generated. Diverted materials are those that are reused, recycled, salvaged, or donated. In this case, the total weight of diverted materials is:8 tons (7.3 tonnes) of recycled demolition steel and concrete 6 tons (5.4 tonnes) of used furniture donated to a non-profit organization 1 ton (0.9 tonnes) of removed carpet and ceiling tiles sent back to the manufacturer 40% of 3 tons (2.7 tonnes) of commingled scrap, which is 1.2 tons (1.1 tonnes) The sum of these weights is 16.2 tons (14.7 tonnes). The total weight of waste generated is 20 tons (18.1 tonnes). Therefore, the percentage of diverted waste is:(16.2 / 20) x 100 = 81%However, the credit allows for a 10% adjustment for vegetative waste, which is not considered a building material. Therefore, the percentage of diverted waste after adjustment is:(81 - 10) = 71%The closest answer option to this value is B. 75%.

A LEED Building Design and Construction project includes an outdoor stage for theatrical performances. In pursuit of Sustainable Sites Credit, Light Pollution Reduction the engineer has specified an LED fixture to illuminate actors on the stage while limiting light pollution. Which of the following suggestions should the LEED AP give to the project owner?
The Sustainable Sites Credit, Light Pollution Reduction aims to minimize the adverse effects of artificial lighting on the night sky, human health, and wildlife. However, the credit does not apply to lighting that is required for safety, security, or emergency purposes. According to the LEED Reference Guide for Building Design and Construction, lighting for theatrical performances is considered an emergency purpose and is exempt from the credit requirements. Therefore, the LEED AP should inform the owner that the LED fixture is exempt from Sustainable Sites Credit, Light Pollution Reduction and does not need to be modified or compared to an alternative. Enclosing the performance areas would not reduce light pollution, but rather increase energy consumption and affect the outdoor experience. Calculating the return on investment over the 20-year life of the project is irrelevant to the credit and would not help achieve it.

During the early stages of a LEED for Schools project, the team was able to reduce the number of lighting fixtures in classrooms by 25% because the project team selected paint color whose light reflectance value was 75% instead of the initially proposed 64% value. This strategy is an example of applying which of the following credits to the project?
The Integrative Process Credit is a credit in LEED Building Design and Construction that supports high-performance, cost-effective project outcomes through an early analysis of the interrelationships among systems. The credit requires project teams to perform analyses for both energy- and water- related systems before completing the schematic design, and to use the findings to inform the owner's project requirements, basis of design, and design and construction documents. The example given in the question is an illustration of how selecting a paint color with a higher light reflectance value can reduce the energy use and cost of lighting fixtures, which is an energy-related system. This strategy shows how the project team applied an integrative process to evaluate the impacts of different design options on the building performance and environmental benefits. Therefore, the correct answer is B. Integrative Process Credit.
