LEED (Leadership in Energy and Environmental design) is an independent, third-party certification system and benchmark that designates a building, home or community as designed and built with strategies aimed at achieving high performance in areas of human and environmental health including sustainable site development, water savings, energy-efficiency and materials selection and indoor environmental quality.
Who uses LEED?
Architects, designers, construction managers, facility managers, engineers, real estate professionals and government officails as they work to ensure new construction and major renovations, existing buildings, neighborhoods, retail establishments, healthcare facilities, commercial interiors, core and shells, schools, and homes are designed and built with sustainable, energy-efficient resources.
How does LEED work?
Building projects earn LEED points for satisfying specific green building requirements. Within each credit category a project must fulfill prerequisites and earn points in order to achieve LEED certification. The number of points earned determines the level of LEED certification. Out of a possible 100 points, 6 Innovation and Design points and 4 Regional Priority points, LEED certification levels are achieved as follows:
Certified (40-49 points)
Silver (50-59 points)
Gold (60-79 points)
Platinum (80+ points)
How can energy-efficient task lighting help earn LEED points?
The most efficient and cost-effective way to illuminate a space is through a combination of ambient and task lighting.
- Energy and Atmosphere: By using a combination of energy-efficient task lighting and low wattage ambient lighting LEED points can be earned through a percent reduction in lighting power density below ASHRAE 90.1-2007 and Title 24 Standards.
- Materials and Resources: LEED points can be earned through the use of salvaged, refurbished or reused materials or by increasing the percentage of task lights which include recycled materials.
- Indoor Environmental Quality: By providing individually controllable task lighting for 90% of a building's occupants LEED points can be earned.
Why use LEED?
Green building is the way of the future. LEED certified projects have third party confirmation that green building features will provide lower operating and maintenance costs and allow for healthier indoor environments through conservation. Certified buildings typically outperform conventional buildings in terms of occupancy rates, sales prices and rental rates as occupants seek to earn recognition for their conservation efforts, financial savings and improved well-being.
