The most appropriate LEED rating system for a mobile home is LEED for Homes. This rating system is designed for residential projects and is suitable for a mobile home located in a downtown area of a major city. Since the project is a home and not a commercial or public building, the LEED for Homes rating system would provide the best fit for certification.

References: The LEED for Homes rating system is outlined as suitable for residential projects, including homes like the one described, in the resources provided by the U.S. Green Building Council12.

A LEED project located within a LEED for Neighborhood Development (LEED-ND) certified boundary is eligible for points under the Location and Transportation Credit, LEED for Neighborhood Development Location. If the development is certified at the Silver level, the project automatically earns 10 points. In addition to these points, the project can earn up to 8 more points in the Location and Transportation category for implementing strategies such as reducing parking footprint, promoting alternative transportation, and connecting with amenities1.

Exemplary performance in LEED is typically achieved by significantly exceeding the requirements for a credit. In the case of water savings, exemplary performance can be achieved by demonstrating a level of water savings that is substantially higher than the standard requirement. A 55% potable water savings would represent a significant reduction in water use and could qualify for an exemplary performance credit under the LEED v4 ID+C rating system.

 Advanced Energy Metering is the credit that works synergistically with the Energy and Atmosphere Credit, Enhanced Commissioning. This is because Advanced Energy Metering involves the implementation of submetering systems that provide data on the building’s energy use. This data is crucial for the ongoing commissioning process to ensure that the building’s systems are operating as intended over time. The data helps in identifying opportunities for energy savings and ensures that energy conservation measures continue to perform optimally12.

For LEED Indoor Environmental Quality Credit concerning Interior Lighting, Option 1, the requirement is for 90% of building occupants to have individual lighting controls. Given that the tenant space includes 100 workstations and 10 enclosed offices intended for individual use, this means that a total of 110 workspaces require lighting control. To achieve one point, at least 90% of these occupants must have control over the lighting in their space. Therefore, the minimum number of occupants that would need individual lightingcontrols is 90% of 110, which calculates to 99 occupants (rounded down). However, as individual controls cannot be split between occupants, the actual minimum number would be 99 occupants. Option B is the closest answer to 99 without going under the required percentage.

References:Explanation of the requirements for individual lighting controls to meet the Interior Lighting Credit under Indoor Environmental Quality, indicating that 90% of building occupants must have task lighting .

The ANSI/ASHRAE/IESNA Standard 90.1-2010 is the benchmark for energy efficiency in building design, providing minimum requirements for the energy-efficient design of buildings except low-rise residential buildings. It is directly referenced in LEED v4 for the Energy and Atmosphere Credit, Optimize Energy Performance, as it sets the baseline for energy performance.

References: The LEED v4 Reference Guide for Interior Design and Construction specifically mentions ANSI/ASHRAE/IESNA Standard 90.1-2010 as a key standard for establishing the baseline for the Energy and Atmosphere Credit, Optimize Energy Performance12.

The LEED v4 criteria for the Energy and Atmosphere Credit, Advanced Energy Metering, Option 2 requires advanced energy metering for all whole-building energy sources as well as for any individual energy end uses that account for 10% or more of the total annual consumption of the building. From the provided energy end-use consumption data, it is clear that space cooling, interior fans, and receptacles each represent more than 10% of the total energy consumption. Additionally, interior lighting and space heating together also account for a significant portion of the energy consumption. Hence, to meet the creditrequirements, advanced metering must be installed for all these categories, aligning with option C.

References:Guidance from the LEED study guide explaining the requirements for advanced energy metering under the Energy and Atmosphere Credit, particularly for end uses that comprise 10% or more of total consumption .

 The Construction and Demolition Waste Management Calculation requires information about the waste stream (the different types of materials being disposed of), the total amount of waste generated, the amount of waste diverted from landfill through recycling or reuse, and the amount of waste that is actually sent to the landfill.

References: This information aligns with the LEED AP Interior Design + Construction (LEED AP ID+C) V4 guidelines, which emphasize the importance of waste management planning in sustainable building practices1.

Best practices for ensuring that minimum program requirements (MPRs) for LEED certification are met involve confirming these requirements early in the project lifecycle. Specifically, this confirmation should occur during the discovery phase, which is the initial stage of a project. The discovery phase involves beginning initial research and analysis, and when sufficient information has been gathered, a goal-setting workshop is held to discuss findings. Part of these findings should include checking that the project complies with the MPRs for the applicable LEED rating system. Confirming MPRs during this early phase helps in setting a clear direction for the project and ensures that all subsequent work is aligned with LEED's fundamental requirements, facilitating a smoother certification process.

Occupancy numbers are a critical factor in multiple LEED credits as they directly influence calculations related to the usage and efficiency of resources and amenities. For the Location and Transportation Credit, Access to Quality Transit, knowing the occupancy numbers helps in understanding the potential demand for public transit facilities. Similarly, for the Water Efficiency Credit, Indoor Water Use Reduction, occupancy numbers are essential for accurately calculating water use and setting reduction targets. Lastly, the Indoor Environmental Quality Credit, Quality Views, considers the occupants' access to natural vistas, which is influenced by the number of people using the space. Consistent reporting of occupancy numbers ensures that the assessments for these credits are based on accurate and comparable data, reflecting the true usage patterns and needs of the building.References:

The primary role of a LEED AP during the LEED certification process is to assist project team members in understanding the LEED rating system. A LEED AP possesses advanced knowledge in green building practices and expertise in a specific LEED rating system, which enables them to facilitate the project’s certification process by guiding the team through the requirements and credits of the LEED system1.

References:

• Information about the role of LEED AP can be found in the LEED professional credentials section on the U.S. Green Building Council website1.
• Additional details on the responsibilities and benefits of being a LEED AP are available in resources provided by the Green Building Certification Institute and other green building education platforms23.

To document the non-structural elements that will be reused in a LEED AP Interior Design and Construction project, it is necessary to have drawings that indicate the elements to be reused. These drawings provide a visual representation of what is being kept from the existing space. Additionally, a tracking spreadsheet is essential for documenting the detailsof these elements, including their condition, location, and any other relevant information that supports the reuse strategy.

References: The information aligns with the LEED v4.1 requirements for Interiors Life-Cycle Impact Reduction, where documentation of reused non-structural elements is part of the credit achievement process1.

The view factor is a measure used in LEED to quantify the quality of views for occupants within a space. In the Indoor Environmental Quality Credit, Quality Views, the rating scale for view factors ranges from 0 (no view) to 5 (maximum view). In the provided diagram, it appears that the space has large windows that provide ample daylight and a view to the outside, which is a key consideration for quality views.

Although the specific outdoor view cannot be determined from the diagram alone, the presence of large windows and the potential for expansive views suggests a high view factor. View Factor 4 is typically assigned to spaces where the view window head height is at least 7 feet 6 inches above the floor, allowing occupants a clear line of sight to the outdoors. This would contribute significantly to the occupants' connection with the outdoor environment, thus scoring higher on the scale.

It is important to note that the exact view factor cannot be precisely determined without additional context regarding the actual visible content outside the windows. However, based on the scale provided and typical LEED scoring, View Factor 4 seems appropriate given the sizeable windowed areas depicted, assuming they provide a clear and unobstructed view to the exterior.References:

• LEED v4 for Interior Design and Construction Reference Guide, specifically the section on Indoor Environmental Quality Credit, Quality Views

For the Location and Transportation Credit concerning Bicycle Facilities, the LEED v4.1 reference guide specifies that the bicycle network must connect to at least eight diverse uses. This requirement ensures that cyclists have access to a variety of services and amenities, promoting the use of bicycles as a sustainable mode of transportation.

References: This requirement is detailed in the LEED v4.1 reference guide for Interior Design and Construction under the section for Location and Transportation Credit: Bicycle Facilities123.

Reusing existing materials from another building, like the raised flooring in this case, contributes to the LEED goal of reducing the demand for virgin materials and minimizing environmental impact. This reuse can be considered as part of the Building Life Cycle Impact Reduction credit, which falls under the umbrella of Materials and Resources credits. Specifically, Option 3 of this credit deals with building and material reuse. By refurbishing and reinstalling an existing raised floor, the tenant's actions demonstrate leadership in extraction practices because they are extending the lifecycle of existing materials, thereby reducing the need for new materials and the environmental burden associated with material extraction and processing.

According to the LEED AP ID+C reference guide, for the purpose of achieving the Indoor Environmental Quality Credit under Enhanced IAQ Strategies, CO2 monitoring should be implemented in all densely occupied spaces1. The public areas of a hotel, including the front desk, lobby, restrooms, and corridor, are typically not considered densely occupied spaces. Therefore, a single CO2 monitor in a central location like the lobby could suffice for the entire public area to meet the requirements of the credit.

For the Indoor Environmental Quality Credit, Quality Views, the LEED v4 reference guide specifies that all regularly occupied spaces must be considered when calculating the percentage with Quality Views. Conference rooms are typically designed for regular occupancy and therefore must be included in the calculation. Spaces like copy rooms and break rooms may not be considered regularly occupied, and lobbies, while they may be occupied, are not spaces where people spend extended periods of time during which they would benefit from quality views.

References: The information is based on the LEED v4 Reference Guide for Interior Design and Construction, which applies to projects that are a complete interior fit-out and includes guidelines for achieving prerequisites and credits related to Indoor Environmental Quality12.

Indoor Environmental Quality Credit for Quality Views emphasizes the importance of providing occupants with a connection to the natural outdoor environment through window views. This credit specifically targets regularly occupied spaces. Among the options listed, conference rooms are typically considered regularly occupied spaces where occupants spend a significant portion of their time and can benefit from quality views. In contrast, copy rooms and office building lobbies are not typically areas where occupants spend extended periods, and break rooms, while important, are not always prioritized for external views in the same way that spaces designated for focused work or meetings, like conference rooms, are.References:

In the context of LEED AP Interior Design + Construction, public restrooms are considered nonregularly occupied spaces. This classification is based on the nature of the space usage, which does not require continuous thermal comfort controls due to the intermittent and brief occupancy. Therefore, thermostats in such spaces can be eliminated during value engineering to optimize resource allocation without compromising the comfort of regular occupants.
