Green Tips
- Use controls that turn off electric lighting in response to natural light levels to reduce energy consumption.
- Use sustainable lighting practices such as occupant sensors to decrease utility costs.
- Limit the use of accent lighting to specific artwork or educational items to reduce energy consumption.
- Incorporate daylighting or views to the outside to create an inviting, ascetically pleasing environment as natural light is usually preferred to artificial lighting.
- Use efficient LED task lighting to reduce energy consumption while providing occupants control of the light levels.
- Use direct-indirect lighting to contribute to an efficient lighting system.
- Use efficient fluorescent lamps as they do not give off as much heat and have a long useful life.
- Use efficient LED task lighting to reduce energy consumption while providing occupants control of the light levels.

Guiding Principles
-
Environmentally Preferable Product ( Guiding Principles, Executive Order 13514 & 13423 [EB, NC])
Use products that have a lesser or reduced effect on human health and the environment over their lifecycle when compared with competing products or services that serve the same purpose. A number of standards and ecolabels are available in the marketplace to assist specifiers in making environmentally preferable decisions. For recommendations, consult the Federal Green Construction Guide for Specifiers.
-
Energy Efficiency ( Guiding Principles, Executive Order 13514 & 13423 [NC])
Establish a whole building performance target that takes into account the intended use, occupancy, operations, plug loads, other energy demands, and design to earn the ENERGY STAR - targets for new construction and major renovation where applicable. For new construction, reduce the energy use by 30 percent compared to the baseline building performance rating per the American National Standards Institute (ANSI)/American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc., (ASHRAE)/Illuminating Engineering Society of North America (IESNA) Standard 90.1-2007, Energy Standard for Buildings Except Low-Rise Residential. For major renovations, reduce the energy use by 20 percent below pre-renovations 2003 baseline. Laboratory spaces may use the Labs21 Laboratory Modeling Guidelines. Use ENERGY STAR and FEMP-designated Energy Efficient Products, where available.

Daylighting and Lighting Controls ( Guiding Principles, Executive Order 13514 & 13423 [EB])
Automated lighting controls (occupancy/vacancy sensors with manual-off capability) are provided for appropriate spaces including restrooms, conference and meeting rooms, employee lunch and break rooms, training classrooms, and offices. Two options can be used to meet additional daylighting and lighting controls performance expectations: ? Option 1: Achieve a minimum daylight factor of 2 percent (excluding all direct sunlight penetration) in 50 percent of all space occupied for critical visual tasks, or? Option 2: Provide occupant controlled lighting, allowing adjustments to suit individual task needs, for 50% of regularly occupied spaces.

Energy Efficiency ( Guiding Principles, Executive Order 13514 & 13423 [EB])
Three options can be used to measure energy efficiency performance: Option 1: Receive an ENERGY STAR rating of 75 or higher or an equivalent Labs21 Benchmarking Tool score for laboratory buildings, Option 2: Reduce measured building energy use by 20% compared to building energy use in 2003 or a year thereafter with quality energy use data, or Option 3: Reduce energy use by 20% compared to the ASHRAE 90.1-2007 baseline building design if design information is available. Use ENERGY STAR and FEMP-designated Energy Efficient Products, where available.
