For projects seeking to comply with Option 1, Lighting Control of the Indoor Environmental Quality Credit for Interior Lighting, LEED guidelines specify that at least 70% of individual occupant spaces must have individual lighting controls. These controls allow occupants to adjust lighting to suit their task needs and pReference, contributing to energy savings and increased occupant comfort and productivity.

This requirement is outlined in the LEED for Building Operations and Maintenance (O+M) Reference Guide, under the Indoor Environmental Quality Credit for Interior Lighting. It is a well-known requirement discussed in LEED AP O+M training and resources, promoting energy efficiency and occupant comfort in the interior environment.

The LEED for Existing Buildings: Operations & Maintenance (LEED EB: O&M) rating system includes a credit category called Materials and Resources (MR). Under this category, there is a credit called ''Sustainable Purchasing -- Ongoing Consumables'' (MR Credit 1). This credit covers product purchases for the building and areas within the site manager's control.One of the criteria for this credit is that food and beverages must be labeled USDA Organic1. Therefore, a USDA organic food product would qualify under this credit.

The decision to replace Chlorofluorocarbon (CFC) and Hydrochlorofluorocarbon (HCFC) refrigerants with alternative refrigerants is not straightforward and involves tradeoffs.While alternative refrigerants like HFCs were commercialized in the 1990s as a replacement for CFCs and HCFCs, they have a strong heat-trapping effect that contributes to global warming1. Therefore, while they solve one problem (ozone layer depletion), they create another (global warming).This means that while they are alternatives, they may increase energy use and greenhouse gas emissions1.

When calculating the Water Efficiency Credit for Outdoor Water Use Reduction, the irrigation of athletic fields may be included or excluded based on the project's specific circumstances and goals. This flexibility allows projects to tailor their water efficiency strategies to their unique site conditions, uses, and priorities, ensuring that the approach to outdoor water use reduction is both practical and effective. Reference: The Water Efficiency section of the LEED O+M Reference Guide provides guidance on calculating outdoor water use, offering options for including or excluding certain areas like athletic fields to meet the project's needs.

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.
