Leadership in Energy and Environmental Design for Commercial Interiors – LEED-CI LEED-CI addresses performance areas including: selection of tenant space; in LEED certified buildings or buildings with sustainable attributes; efficiency of water usage; energy performance optimization including lighting and lighting controls; HVAC Systems, and equipment; resource utilization for interior building systems and furnishings, and indoor environmental quality including criteria for emissions, thermal comfort, daylight and views. Note: Some of the criteria are similar to the requirements for LEED-NC certification, but with different point allocations.

CATEGORY: Sustainable Sites/SS Option F "Light Pollution Reduction" 1/2 point
Intent: Encourage tenants to select buildings with best practices systems and employed green strategies.
Requirement: Select a LEED Certified Building OR locate the tenant space in a building that has in place two or more characteristics of LEED.
Selecting a LEED Certified Building earns 3 points. Alternatively, points are obtained by locating tenant space in a building with certain characteristics, such as meeting or providing lower light levels and uniformity ratios than those recommended by the IESNA Recommended Practice Manual: Lighting for Exterior Environments.
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 & Atmosphere Minimum Energy Performance Required
Intent: Establish the minimum level of energy efficiency for the tenant space system.
Requirement: This is the same requirement as in LEED-NC. The project must comply with ASHRAE/IESNA Standard 90.1-2001, or the local energy code, whichever is more stringent. ASHRAE/IESNA Standard 90.1-2004 will become the referenced standard when available.
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.
| HID opportunities: |

| Upgrade from a magnetic HID ballast to an electronic HID ballast |
15% energy savings |
| Use Pulse start (or ceramic metal halide) instead of probe start lamps |
up to 36% energy savings |
| Consider substituting high pressure sodium lamps with whiter light sources (CF/MH) if energy savings is achieved and IES levels are met |

| 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 |

| Incandescent and Halogen opportunities: | Savings: |
Convert all standard incandescent lamps to Capsylite or Compact Fluorescent Lamps (CFLs) | Up to 75% energy savings |
CATEGORY: Energy & Atmosphere Credit #1.1 Optimize Energy Performance, Lighting Power 3 points
Intent: Achieve increasing levels of energy conservation beyond the referenced standard to reduce environmental impacts associated with excessive energy use.
Requirement: This credit is similar to what is specified in LEED-NC, but with fewer power density options. Requirements include reducing connected lighting power density below that allowed by ASHRAE/IESNA 90.1-2001 (2004 when available) using either the space-by-space method or by applying the whole building lighting power allowance to the entire tenant space.
Points are awarded for reducing lighting power density to 15% below the standard (1 point), 25% below the standard (2 points), or 35% below the standard (3 points).
SYLVANIA Solutions:
Similar strategies to those suggested in the “Minimum Energy Performance” requirement may be applied here.
CATEGORY: Energy & Atmosphere Credit #1.2 Optimize Energy Performance, Lighting Controls 1 point
Requirement: Install daylight responsive controls in all regularly occupied spaces within 15 feet of windows and under skylights.
SYLVANIA Strategies:
Controls manufacturers can help design installations that best meet the customer’s lighting control needs. Dimming and DALI dimming ballasts are ideal for Daylight Harvesting, whereby each fixture (or row of fixtures)regulates the light output to compensate for changes in natural daylight.
CATEGORY: Materials and Resources Credit #5.1 Regional Materials, 20% Manufactured Regionally 1 point
Intent: Increase demand for building materials and products that are extracted and manufactured within the region, thereby supporting the regional economy and reducing the environmental impacts resulting from transportation.
Requirement: Use a minimum of 20% of the combined value of construction and Division 12 (Furniture and Furnishings) materials and products that are manufactured regionally within a radius of 500 miles.
SYLVANIA Strategies:
Luminaire manufacturers within your region may be able to include Sylvania products in the fixtures you are considering for the project.
CATEGORY: Indoor Environmental Quality Credit #6.1 Controllability of
Systems, Lighting 1 point
Intent: Provide a high level of lighting system control for individual occupants, and specific groups in multi-occupant spaces (e.g. classrooms and conference areas), to promote the productivity, comfort and well-being of building occupants.
Requirements: Provide lighting controls for at least 90% of occupants, enabling adjustments to suit individual task needs and preferences, AND all shared multi-occupant spaces where transient groups must share lighting controls.
SYLVANIA Strategies:
Controls manufacturers can help design installations that best meet the customer’s lighting control needs. Sylvania Programmed Start ballasts are the best to use when the switching cycles are frequent or unknown. Additionally, dimming and DALI dimming ballasts can be integrated with Daylight Harvesting and Building Management Systems for higher levels of control and comfort.
