The Leadership in Energy and Environmental Design (LEED) Green Building Rating System™
The Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ encourages and accelerates global adoption of sustainable green building and development practices through the creation and implementation of universally understood and accepted tools and performance criteria.
LEED is designed to promote design and construction practices that increase profitability while reducing the negative environmental impacts of buildings and improving occupant health and well-being.
LEED makes this possible by providing building owners and operators with a concise framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions.
LEED promotes a whole-building approach to sustainability by recognizing performance in five key areas of human and environmental health:
- Sustainable site development
- Water efficiency
- Energy efficiency
- Material selection
- Indoor environmental quality
Stanpro’s Picogram per
The Picogram per Lumen-Hour Calculator shows you your project’s lamp mercury picogram rating* and the number of LEED certification points you could qualify for by using Standard-Stanpro’s products.
This tool will calculate the picograms per lumen-hour:
- Select the “Brand” and “Lamp type”, followed by the “Lamp”, and the rest of the information in the table will automatically populate itself.
- Enter the number of lamps per fixture as well as the amount of fixtures used. This will determine the picogram for a specific area.
In LEED “Leadership in Energy and Environmental Design”, specific lamps may contribute to the achievement of various LEED credits. This score is known as the picogram per lumen-hour score.
- MR Credit 4.1 (1 point): 90 picograms per lumen-hour
- MR Credit 4.2 (2 points): 70 picograms per lumen-hour
A rating below 90.00 is considered to be in compliance with the LEED-EB certifications’ standards.
* Using green products and materials may contribute to a building’s LEED certification.
