Leadership in Energy and Environmental Design for Existing Buildings -- LEED-EB
LEED-EB is specifically tailored for retrofit and upgrade projects. Additionally, buildings certified under the LEED-NC criteria hold that distinction for up to five years, after which they would use the LEED-EB standards for recertification. LEED-EB addresses system upgrades to improve energy, water, indoor environmental quality and materials use, and to reduce the environmental impact of a building over its functional life cycle.

Unlike LEED-NC, there are prerequisites in several categories of the LEED-EB criteria. A project must meet ALL the pre-requisites in the rating system to be considered for LEED certification.
CATEGORY: Sustainable Sites/SS Credit #8 "Light Pollution Reduction" 1 point
Intent: Eliminate light trespass from the building and site, improve night sky access and reduce development impact on nocturnal environments.
Requirements: Shield all outdoor luminaries >50 watts or show that less than 5% of light emitted reaches the night sky on an annual basis, and perimeter illumination levels measured with lights on must not be more than 10% above the levels measured with the lights off.
SYLVANIA Strategies:
Specially designed luminaires, combined with lower wattage light sources, can effectively minimize light trespass. Replacing high-pressure sodium (HPS) lamps with “white” sources can be an effective strategy, especially at lower light levels. Make sure not to go below IES recommended levels, and talk with your luminaire manufacturer or representative agencies about these types of options.
CATEGORY: Energy and Atmosphere/EA Prerequisite #2 "Minimum Energy Performance" REQUIRED
Intent: Establish the minimum level of energy efficiency for the building and systems.
Requirements: Demonstrate that the building has achieved an EPA Energy Star score (or equivalent) of at least 60 using the US EPA Energy Star Benchmarking Tool.
SYLVANIA Strategies:
The Energy Star Benchmarking Tool measures comprehensive energy performance for a building, as compared to other similar buildings. The Benchmarking Tool is available online at www.energystar.gov and should be completed first by the building owner or project specifier. In the meantime, determine the baseline installation and identify energy-efficient alternatives by area or fixture type.
Sylvania offers many energy-efficient options for increasing energy performance once a baseline is established.

Energy Savings |
| Retrofit magnetically ballasted 12 fixtures with electronic ballasts and T8 |
30-45% energy savings |
|
Upgrade from electronically ballasted 700 series T8s to electronically ballasted FO30or FO28 SUPERSAVER® T8s |
12% additional energy savings |
| Upgrade from standard IS electronic ballasts to QHE (High Efficiency) IS electronic ballasts |
6% additional savings |
| Use T8 IS Low Ballast Factor (BF) ballasts to replace Normal BF electronic ballasts |
12% additional energy savings |
| Higher BF (e.g.1.2 BF) electronic ballasts with high lumen lamps (e.g. FO32W XP) can reduce number of lamps needed, where it’s feasible |
e.g. use 2 vs. 3 T8 lamps, obtain 10% energy savings |
| See T5HO options outlined above, in the HID Opportunity section |
varies |
| Upgrade from 3L electronically ballasted parabolic fixtures, (87W) to 2L “RT5” Volumetric Recessed fixtures (60 /58W) |
33% additional energy savings |
| Incandescent and Halogen opportunities: |
Savings: |
|
Convert all standard incandescent lamps to Capsylite or Compact Fluorescent Lamps (CFLs) |
Up to 75% energy savings |
CATEGORY: Materials and Resources/MR Prerequisite #2 "Toxic Material Source Reduction -- Reduced Mercury in Light Bulbs" REQUIRED
Intent: Establish and maintain a toxic material source reduction program to reduce the amount of mercury brought into buildings through purchases of light bulbs.
Requirements: Maintain mercury content of all mercury containing light bulbs below 100 picograms per lumen hour of light output, on weighted average, for the existing building and associated grounds.
Calculation for weighted average is:
Picograms of Hg in all lightbulbs acquired during performance period
Rated hours X mean light output at 40% of life
SYLVANIA Strategies:
LEED-EB requires an application to specify the intended products for the project. The project implementation does not have to be immediate, so specifying products available later in the year is perfectly acceptable. OSRAM SYLVANIA is committed to reducing the mercury content in our lamps as much as we are committed to providing high-quality, high-performing products.
In the fall of 2005, the mercury content in our OCTRON T8 800, 800Xp and 800XPS series 4-ft linear fluorescent lamps will be at or below the maximum picogram per lumen-hour requirement set for LEED-EB. Beginning in the 4th quarter of 2005, these lamps will have a mercury content of <3.5 mg. SYLVANIA Pentron T5 lamps also meet the lower mercury thresholds with <2.5 mg mercury.
Given that the requirement is for a weighted average, Sylvania currently offers numerous energy-saving options that help meet the minimum picogram requirement and can reduce electricity demand significantly to meet a project’s overall goals. Using the FO30/800/XP/SS and FO28/800/XP/SS with QHE ISN or ISL ballast are excellent examples of systems that are helpful in meeting this requirement.
CATEGORY: Materials and Resources/MR Credits #5.1, 5.2, 5.3 "Occupant Recycling" 1 to 3 points
Intent: Facilitate the reduction of waste and toxins generated by building occupants and building operations that is hauled to and disposed of in landfills.
Requirements: Collect and recycle at least 95% of the fluorescent lamps used and 95% of the batteries used AND divert/recycle 30% (1 point), 40% (2 points) or 50% (3 points) of total waste stream by weight or volume
SYLVANIA Strategies:
Sylvania Lighting Services sends all spent lamps to a bone fide recycling facility upon completion of a retrofit or maintenance project.
OSRAM SYLVANIA promotes recycling as the responsible method for lamp disposal and encourages distributors to offer recycling programs to their customers.
Category: Materials and Resources/MR Credit #6 "Additional Toxic Material Reduction: Reduced Mercury in Light Bulbs" 1 point
Intent: Establish and maintain a toxic material source reduction program to reduce the amount of mercury brought into buildings through purchases of light bulbs.
Requirements: Maintain mercury content of all mercury-containing light bulbs below 80 picograms per lumen hour of light output (picogram/lumen hour), on weighted average, for all mercury-containing light bulbs acquired for the existing building and associated grounds. (The weighted average mercury content of these light bulbs is calculated as described in MR Prerequisite 2).
CATEGORY: Indoor Environmental Quality/IEQ Credit #6.1 "Controllability of Systems -- Lighting" 1 point
Intent: Provide a high level of temperature, ventilation and control by individual occupants or specific groups in mulit-occupant spaces to promote the productivity, comfort and well-being of building occupants
Requirement: Provide controls for at least 50% of building occupants, enabling adjustments to suit individual task needs and preferences, or those of a group sharing a multi-occupant space
SYLVANIA Strategies:
Controls manufacturers can help design installations that best meet the customer’s control needs. Sylvania Programmed Start ballasts are the best to use when the switching cycles are frequent or unknown. Additionally, Quicktronic® PowersenseTM T8 Dimming and DALI dimming ballasts can be integrated with Daylight Harvesting and Building Management Systems for higher levels of control and comfort.
CATEGORY: Innovation and Upgrades, Operations and Management/IUOM Credit #1 1-4 points
Intent: To provide design teams and projects the opportunity to be awarded points for exceptional performance above the requirements set by the LEED Rating System
SYLVANIA Strategies:
SYLVANIA sales teams can help you substantially exceed the LEED-NC energy performance credit with our innovative energy-efficient and long-life products. For example, Sylvania PLANON and LED products reduce maintenance requirements and provide exemplary with fewer materials to be disposed of at end of life. In addition, SYLVANIA sales teams can help you develop education and training for the occupants of the conditioned space to help them understand the energy-saving and benefits of SYLVANIA products.
