The LEED applicant must exclude the purchases of the other tenants from the Materials and Resources credit calculations, because they have not provided purchasing data and are not participating in the LEED project. The LEED applicant can only include the purchases that are under their control and can be verified.

For the Sustainable Sites Credit, Light Pollution Reduction, fixtures with a minimum of 1,500 lumens must be partially or fully shielded. This requirement helps to minimize light trespass and sky glow, contributing to the reduction of light pollution.

References: The LEED v4.1 O+M reference guide specifies the need for shielding on outdoor light fixtures to control light pollution.The threshold for lumens is set to ensure that lighting is designed to conserve the night sky1.

For the Sustainable Sites Credit, Light Pollution Reduction, outdoor light fixtures that directly emit light into the night sky and have a minimum lamp lumens exceeding 1,500 must be partially or fully shielded. This requirement is aimed at reducing light pollution by ensuring that outdoor lighting fixtures are designed and installed in a manner that minimizes sky glow and light trespass, thereby preserving the natural night environment.

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.

When adding a new space within a facility to the ENERGY STAR® Portfolio Manager, the required information includes the space floor area and hours of operation1. The tool helps building owners and tenants measure and track energy, water use, and waste, all in a secure online environment1. It is important to note that to receive an ENERGY STAR score in Portfolio Manager, you must enter 12 full calendar months of energy data for all energy types, in addition to complete data on property use details such as hours of operation and workers2.
