According to the LEED v4: Building Design + Construction Guide, the bicycle network must connect to

a rapid transit stop that is within 3 mi. (5 km) biking distance of the project boundary. This is one of

the options to meet the requirement for Option 1: Bicycle Network and Storage. The other options

are to connect to at least 10 diverse uses or to connect to a school or employment center that is

within 3 mi. (5 km) biking distance of the project boundary. Reference: LEED v4: Building Design +

To achieve the Sustainable Sites Credit, Light Pollution Reduction, Option 1. BUG Rating Method,

projects must demonstrate that all luminaires meet acceptable fixture ratings for the project’s Model

Lighting Ordnance (MLO) lighting zone. The MLO lighting zone is determined by the site-specific

characteristics and the definitions provided in the IES/IDA MLO User Guide1. The fixture ratings are

based on the backlight-uplight-glare (BUG) system, which measures the amount of light emitted in

different directions by a luminaire, as defined in IES TM-15-11, Addendum A2. The maximum

allowable ratings for each lighting zone are given in Table 1 of the credit language3. Reference:

IES/IDA MLO User Guide; IES TM-15-11, Addendum A; Light pollution reduction

According to the LEED v4: Building Design + Construction Guide, the Water Efficiency Prerequisite,

Indoor Water Use Reduction requires the project to reduce the aggregate water consumption from

plumbing fixtures and fittings by at least 20% from the baseline. The baseline water consumption is

determined by the Energy Policy Act of 1992 and subsequent rulings by the Department of Energy, or

a local equivalent for projects outside the U.S. The plumbing fixtures and fittings that apply to the

calculations are toilets, urinals, lavatory faucets (both private and public), showerheads, and kitchen

sink faucets1. Pre-rinse spray valves, dishwashers, and commercial kitchen filling operations faucets

are not included in the calculations, as they are considered process water uses1. Therefore, the

correct answer is C, urinals, public lavatory faucets, kitchen sink faucets. Reference: LEED v4: Building

New Construction is the appropriate rating system for a new mixed-use building with 300,000 ft2 (27

871 m2) of residential units, 150,000 ft2 (13 935 m2) hotel and 50,000 ft2 (4 645 m2) of retail space.

According to the LEED rating system selection guidance1, the New Construction rating system applies

to buildings that are being newly constructed or going through a major renovation, and that include

any of the following use types: office, retail, hospitality, education, residential, warehouse and

distribution centers, or data centers2. The New Construction rating system can also be used for

mixed-use buildings that have more than one use type3. Since the project involves new construction

of a mixed-use building with residential, hospitality, and retail uses, the New Construction rating

system is the most suitable option. The other rating systems are not applicable because they are

either specific to one use type (Retail and Hospitality) or to buildings that are not complete at the

time of certification (Core and Shell Development). Reference:

The Energy and Atmosphere Prerequisite, Minimum Energy Performance, Option 2. Prescriptive

Compliance: ASHRAE 50% Advanced Energy Design Guide allows projects to follow the

recommendations of the ASHRAE 50% Advanced Energy Design Guides (AEDGs) for different building

types and climate zones. The AEDGs provide design guidance for buildings that use 50% less energy

than those built to the requirements of the ANSI/ASHRAE/IES Standard 90.1-2004 commercial code1.

However, not all building types and sizes are covered by the AEDGs. According to the LEED Reference

Guide for Building Design and Construction2, the following building types and sizes are eligible for

this option:

Small to Medium Office buildings up to 100,000 ft2 (9 290 m2)

Medium to Large Retail buildings up to 100,000 ft2 (9 290 m2)

K-12 School buildings up to 200,000 ft2 (18 580 m2)

Warehouse and Distribution Center buildings up to 500,000 ft2 (46 450 m2)

Therefore, among the given options, only the school project is eligible to pursue this option, as it falls

within the size limit for the K-12 School AEDG3.

The reuse calculation for MR Credit Building Life-Cycle Impact Reduction includes the surface area of

structural elements that are reused in place or salvaged and reinstalled, such as floor decking,

columns, beams, and roof decking. Exterior glazing and plumbing fixtures are not considered

structural elements and are not included in the reuse calculation. Asbestos insulation is a hazardous

material that should be removed and disposed of properly, not reused. Reference: MR Credit

According to the LEED v4 Reference Guide for Building Design and Construction, the discovery phase

of energy-related systems should identify ventilation rates, along with other factors such as building

orientation, envelope attributes, lighting levels, plug and process loads, and programmatic and

operational parameters1. These factors should be used to create a preliminary “simple box” energy

model to evaluate the energy performance of the building and explore potential strategies to reduce

energy use1. The other options are not relevant for the discovery phase of energy-related systems.

Functional performance tests are part of the implementation phase1. Thermal comfort ranges are

related to indoor environmental quality2. Transportation options are related to sustainable sites3.

Option 1 of the Innovation credit under LEED v4.1 BD+C rating system (Building Design and

Construction) allows for achieving significant, measurable environmental performance using a

strategy not addressed in the LEED green building rating system1. Implementing an employee

engagement and education plan could be a unique strategy that promotes sustainability and

environmental stewardship, which is not specifically addressed in the LEED rating system.

A multiple-zone system is a system that has one or more air handlers supplying conditioned air to

more than one zone. A zone is a space or group of spaces within a building with heating and cooling

requirements that are sufficiently similar so that desired conditions (e.g., temperature) can be

maintained throughout using a single controlling device. The ventilation rate procedure calculations

must be based on the multiple-zone system configuration because the HVAC system in the question

serves different zones with different ventilation requirements. Reference: LEED v4 Reference Guide

According to the LEED v4: Building Design + Construction Guide, Option 2 of the Location and

Transportation Credit, Green Vehicles requires the project to inventory the school fleet to develop

and create a plan for all buses to meet the emission requirements. The plan must include a timeline

for implementation and a budget. The emission requirements are based on the U.S. Environmental

Protection Agency (EPA) standards for heavy-duty vehicles1. Reference: LEED v4: Building Design +
