The Owner Project Requirements (OPR) is a document that details the ideas, concepts, and criteria determined by the owner to be important to the success of the project. It typically includes key functional and operational parameters such as occupied hours of a building, use by space type, required temperature settings, and lighting levels. The OPR is used as a guiding document throughout the design and construction process to ensure that the team is aligned with the owner’s vision and goals.

References: LEED v4: Building Operations + Maintenance Guide, Functional / Operational | WBDG - Whole Building Design Guide, Facilities Operations & Maintenance - An Overview - WBDG

The Owner Project Requirements (OPR) is a critical document that outlines the functional and operational objectives of a project, reflecting the owner's needs and expectations. This document serves as a foundation for the design team to develop the Basis of Design (BOD) and guides the project through its lifecycle, ensuring that the owner's operational needs, such as occupied hours, use by space type, required temperature settings, and lighting levels, are met. The OPR typically includes information on building occupancy schedules, space usage types, environmental conditions like temperature and lighting requirements, and other owner-driven criteria essential for the building's design and operation. By clearly defining these parameters upfront, the OPR ensures that the project team has a clear understanding of what is expected from the building's performance, facilitating a design that aligns with the owner's vision and operational needs.

References:Based on the LEED AP documents and resources, such as the ASHRAE 90.1-2013 User Manual, which provides guidelines for determining design and operational parameters like lighting wattage for various space types (ASHRAE 90.1-2013, Section 9.1.4) .

Air conditioner condensate is considered a non-potable water source that can be used for cooling towers. This is because air conditioner condensate is essentially distilled water, which is produced as a by-product of the air conditioning process. It is free from most impurities found in other water sources, making it an ideal choice for use in cooling towers. Using this source not only conserves potable water but also reduces the load on municipal water supplies.

These guidelines emphasize the importance of reducing transportation-related impacts through alternative commuting strategies.

The Indoor Environmental Quality Prerequisite, Green Cleaning Policy, requires a plan for hazardous spill cleanup. This prerequisite focuses on reducing the exposure of building occupants and maintenance personnel to potentially hazardous chemical, biological, and particulate contaminants, which adversely affect air quality, human health, building finishes, building systems, and the environment. A well-defined spill cleanup plan is crucial for maintaining a safe and healthy indoor environment.References:LEED AP Operations + Maintenance Reference Guide, Indoor Environmental Quality section.

For establishing a baseline in the context of the Water Efficiency Prerequisite, Indoor Water Use Reduction, Option 2, it's critical to have an accurate understanding of the current water usage patterns. This involves metering various water fixtures, including those in commercial kitchens. The goal is to determine the potential for water savings by comparing the baseline data to reduced usage scenarios through efficiency measures.

A 12-month metering period is typically recommended for a few key reasons:

• Seasonal Variability:A year-long period captures the seasonal variations in water use, providing a comprehensive understanding of usage patterns. Commercial kitchens might have fluctuating usage based on seasonal menus, events, and peak times, which shorter periods might not fully capture.
• Data Reliability:A longer data collection period enhances the reliability of the data. It mitigates the impact of any anomalies or outliers that could skew the results in shorter metering durations.
• Consistency with LEED Requirements:LEED guidelines emphasize the importance of thorough and accurate baseline measurements to inform effective water reduction strategies. A 12-month period aligns with the comprehensive approach LEED encourages for sustainable practices.
• Operational Changes:A year gives enough time to observe the effects of any operational changes, special events, or other factors that might influence water usage. This ensures that the baseline is representative of typical operations.

References:The approach aligns with the general LEED principles for establishing baselines for water and energy use, which advocate for capturing data over significant periods to ensure accuracy and reliability. Although the specific LEED BD+C or O+M documentation does not detail the metering period for each specific fixture type, the 12-month period is a widely accepted standard for establishing baselines in building operations, including water usage in commercial kitchens. This duration provides a comprehensive view of water use, accommodating seasonal changes and varying operational activities, which is essential for setting realistic and achievable water reduction goals in line with LEED's sustainability objectives.

The Indoor Environmental Quality Credit for Thermal Comfort under the LEED AP Operations + Maintenance (LEED AP O+M) V4.1 requires continuous monitoring of certain parameters in occupied spaces.

Low Impact Development (LID) practices manage stormwater by using natural or man-made systems to filter and recharge stormwater into the ground12. A rain garden is an example of a LID technique for rainwater management3. It is a planted depression that allows rainwater runoff from impervious urban areas, like roofs, driveways, walkways, parking lots, and compacted lawn areas, to be absorbed. This reduces rain runoff by allowing stormwater to soak into the ground (as opposed to flowing into storm drains and surface waters which causes erosion, water pollution, flooding, and diminished groundwater).

LEED v4.1 O+M Reference Guide, p.1132: LEED v4 - U.S.Green Building Council(https://www.usgbc.org/guide/om) 3: What is Blowdown Loss in Cooling Towers?(https://deltacooling.com/resources/faqs/what-is-blowdown-loss-in-cooling-towers).

Cooling tower blowdown is a process used to manage water quality in cooling systems. It involves discharging a portion of the water from the system to control the concentration of dissolved solids and minerals, which accumulate due to the continuous evaporation of water. These dissolved solids can increase the water's conductivity, leading to scale formation, corrosion, and biofouling, all of which can significantly decrease the efficiency and lifespan of the cooling system. By performing blowdown, the system maintains the water quality within acceptable limits, ensuring optimal performance and energy efficiency of the cooling tower.

References:

• The need for cooling tower blowdown due to the accumulation of dissolved solids is discussed within the context of water management practices in cooling systems in the LEED AP O+M documentation. This process is crucial for maintaining system efficiency and is covered under the Water Efficiency category, emphasizing the importance of water management in achieving sustainable building operations.

Compressed workweeks can help reduce pollution and land development effects from automobile use. This strategy involves working longer hours on fewer days, which reduces the number of commuting trips and thus the associated pollution and land development impacts. It’s one of the alternative transportation strategies recognized by the USGBC in the LEED AP O+M rating system1.

Training building operations staff on operating schedules and requirements is appropriate when implementing changes in the sequence of operation for boilers. This ensures that the staff can effectively manage the new operating sequence to match heating demand, as identified by the ASHRAE Level 2 analysis.

References: The LEED v4.1 O+M reference guide suggests that training should focus on areas directly affected by implemented changes.Since the sequence of operation for boilers has been modified, staff training should cover the new operating schedules and requirements to ensure continued implementation of the change1.

After implementing changes in the sequence of operation for boilers based on an ASHRAE Level 2 analysis, an appropriate topic for training building operations staff is operating schedules and requirements. This training ensures that staff understand and can effectively implement the new operating procedures, maintaining the improved efficiency and performance of the boilers.

Soil testing is an operational element that needs to be tracked only once during the performance period to meet the Sustainable Sites, Site Management Credit. This is because soil testing provides a snapshot of the soil’s condition, which is unlikely to change significantly over short periods.

References: The LEED v4.1 O+M guide indicates that certain site management practices, such as soil testing, do not require continuous monitoring but should be documented at least once during the performance period to ensure compliance with the credit requirements1.

If a manufacturer does not specify the calibration interval for utility meters used for benchmarking building energy performance, the assessment team may specify a reasonable calibration interval not to exceed three years. This calibration ensures the accuracy and reliability of the data collected for energy performance analysis.References:LEED v5 O+M: Existing Buildings beta version

Untreated stormwater, due to its potential contaminants, is not suitable for potable uses but can be effectively utilized for non-potable applications such as irrigation. It provides a viable alternative to using treated water for landscape irrigation, thereby conserving potable water resources. This use aligns with sustainable water management practices encouraged by LEED, which promote the reduction of potable water usage for landscape irrigation.

References:

• The LEED Reference Guide for Green Building Design and Construction and the LEED O+M Reference Guide both encourage the use of untreated stormwater for irrigation as part of an integrated water management approach. This conservation strategy is covered under the Water Efficiency category and is a common topic in LEED AP O+M training sessions.

The view factor is the percentage of the floor area that has a direct line of sight to the perimeter vision glazing.

This answer is correct because these are the two factors that affect the heat island reduction potential of the materials. The SRI is a measure of how well a material reflects solar radiation and stays cool in the sun. The higher the SRI, the lower the surface temperature and the less heat absorbed by the material. The unbound percentage of the open-grid pavement system is the ratio of the area that is not covered by the paving material to the total area of the system. The higher the unbound percentage, the more permeable the system and the more water infiltration and evaporation, which also reduce the surface temperature. The vegetated roof system does not need to have a specific SRI value, as long as it uses native or adapted plant species that provide shade and evapotranspiration. The open-grid pavement system does not need to have a specific SRI value, as long as it has at least 50% unbound area.

When a building is recertified in LEED Operations and Maintenance, it should use the LEED version that is current at the time of registration for recertification. This approach ensures that the building is being assessed under the most recent standards and requirements, reflecting the latest advancements and best practices in green building.References:LEED Operations and Maintenance Reference Guide, Introduction and Overview section.

When a building initially certified under LEED EB v2.0 seeks recertification, the appropriate version to use is the one that is current at the time of registration for recertification. LEED rating systems go through updates and revisions, and at any given point, they can be either open for registration and certification, closed for registration but open for certification, or completely closed for both registration and certification (sunset). The deadlines for these phases are published by the USGBC. Therefore, a building pursuing recertification must align with the most current version available at the time of its registration for recertification.

Using on-site captured rainwater and municipally treated wastewater for both flush fixtures and irrigation can be applied towards the credits for both Indoor Water Use Reduction and Outdoor Water Use Reduction in LEED. These alternative water sources contribute to the overall water efficiency of the project by reducing the reliance on potable water sources for indoor and outdoor uses.

In relation to the baseline water usage for buildings with respect to their certificate of occupancy dates, for buildings dated 1995 or later, the baseline is set at 120% of the water use that would result if all fixtures met the code requirements. This guideline is part of the LEED Operations and Maintenance Rating System's approach to evaluating water use in buildings and setting a baseline for comparison and improvement.References:LEED v5 O+M: Existing Buildings beta version

When the building type is not covered by the ENERGY STAR® rating tool, the energy baseline for Minimum Energy Performance can be determined using historical energy consumption data or a calibrated energy simulation. This approach allows for a tailored assessment of the building’s energy use that is specific to its actual performance.

References: The LEED v4.1 O+M reference materials provide guidance on establishing an energy baseline using historical data or energy simulation methods when ENERGY STAR® ratings are not applicable1234.

To increase the vegetated area of an existing urban site from 4% to equal or be greater than 5%, one effective strategy is to install a vegetated roof system. This approach not only increases the site's vegetated footprint but also provides additional benefits such as improved stormwater management, increased insulation, and reduction of the urban heat island effect. A vegetated roof system can be implemented on flat or slightly sloped roofs, making it a versatile option for urban environments where ground space may be limited. By converting unused roof space into green space, the project team can meet the goal of increasing the total vegetated area of the site.References:LEED Reference Guide for Green Building Design and Construction, U.S. Green Building Council.
