A strategy for preventing light pollution is to install shielded fixtures. Light pollution is the excessive or inappropriate use of artificial lighting that can have adverse effects on human health, wildlife, ecosystems, and astronomy. Shielded fixtures are lighting devices that direct light downward and prevent light from escaping upward or sideways. Shielded fixtures can reduce light pollution by minimizing glare, sky glow, light trespass, and energy waste13. References: LEED v4 Green Associate Candidate Handbook1, International Dark-Sky Association’s Lighting Basics3

Regional Priority credits are awarded to encourage projects to address local environmental issues that are of particular importance or concern for the region where the project is located. These issues may include water scarcity, air quality, habitat protection, or human health. Regional Priority credits are not new LEED credits, but rather existing credits that have been identified by regional councils or chapters of USGBC as having higher priority or relevance for their areas. Projects can earn up to four bonus points by achieving Regional Priority credits. References: LEED v4 BD+C Reference Guide, Introduction, page 13; LEED v4 Impact Category and Point Allocation Process Overview1
