WHAT IS LEED?

LEED Rating SystemTM

– Voluntary, consensus-based rating system– national standard– measuring tool to reward sustainable design

decisions– LEED does not guaranty sustainable design

Leadership in Energy and Environmental DesignLeadership in Energy and Environmental Design

Why Use LEED?

– To measure the sustainable aspects of a project

– To compare the project with other sustainable building projects

– To create an owner’s manual for the building

Introduction to LEED

• LEED does not necessarily produce good lighting design

• It awards points for avoiding some transgressions

– LEED was developed by the U.S. Green Building Council (U.S. Green Building Council (USGBCUSGBC))

– USGBC is a not-for-profit organization comprised of a board of directors & volunteer committees from the building industry

– USGBC decisions are made on a consensus basis

people per square mile according to the last U.S. census. Also for developed areas in state and national parks, areas near astronomical observatories, zoos and ANY area where residents have expressed a desire to maintain a natural nightime environment

SS

2.2 lighting zones

• LZ2 – Low (Residential areas)– For population densities of 200-3000 people

per square mile, according to the last U.S. census. This would include most areas zoned “residential” and is the default zone for residential areas

SS

2.2 lighting zones

• LZ3 – Medium (Commercial/Industrial, High-Density Residential) – For population densities greater than 3,000

people per square mile according to the last U.S. census. This lighting zone is intended for high density urban neighborhoods, shopping and commercial districts and industrial parks. This is the default zone for commercial and industrial areas

SS

2.2 lighting zones

• LZ4 – High (Major City Centers, Entertainment Districts)– This is for major city centers (with population

densities greater than 100,000 according t the last U.S. census), thematic attractions, entertainment districts, and major auto sales districts

SS

Light Trespass

• Design exterior lighting so that all site and building mounted luminaires produce a maximum initial illuminance value no greater than (LZ1=0.01, LZ2=0.10, LZ3=0.20, LZ4= 0.6) horizontal and vertical footcandles at the site boundary and no greater than 0.01 horizontal footcandles (10 feet for LZ1 & LZ2, 15 feet for LZ3 & LZ4) beyond the site boundary

SS

Light Pollution

• Document that (LZ1=0%, LZ2=2%, LZ3=5%, LZ4=10%) of the total initial designed fixture lumens are emitted at an angle of 90 degrees or higher from nadir (straight down)

SS

LZ2, LZ3 & LZ4

• For site boundaries that abut public rights-of-way, light trespass requirements may be met relative to the curb line instead of the site boundary

SS

• FOR MASTER PLAN PROJECTS– Develop exterior lighting master plan that includes

project site & surrounding buildings in a comprehensive manner addressing safety & security issues by sharing exterior lighting amenities while minimizing light pollution & energy consumption. The lighting master plan must show it incorporates the credit requirements as well as:

• How plan reduces light trespass & promotes night sky access and how projects fit into overall design.

• How safety, security, & comfort will be enhanced master plan.

SS

Schools (sports lighting)

• Automatic Shutoff: – All sports lighting shall be automatically

controlled to shut off no later than 11PM. Manual override shall be provided to avoid disruption of school sponsored sporting events.

SS


• Trespass Calculations: – All trespass calculations shall be submitted for

two conditions: – (1) With the sports lighting turned off and all

other site lighting turned on, the light trespass requirements are (LZ1=0.01, LZ2=0.10, LZ3=0.20, LZ4= 0.6), and

SS


• Trespass Calculations: – (2) with just the sports lighting on, the light

trespass requirements for horizontal and vertical footcandles may be increased to the following illuminance levels:

• LZ1 = 0.10• LZ2 = 0.30• LZ3 = 0.80• LZ4 = 1.50

2/2/2004 - Credit Interpretation Request

• Our proposed design for pathway lighting in the middle of a large university campus setting uses pole-mounted IESNA CUTOFF luminaires. The objectives of the lighting design are to provide a safe nighttime environment for students, to minimize light pollution, and to maintain the campus historic aesthetic.

We understand that the intent of the specific requirement for FULL CUTOFF luminaires is to minimize the amount of upward light pollution. After significant research, we have determined that there are no “period-style” luminaires that match the campus standard and meet Full Cutoff classification, due to the nature of their design. We have also determined that it will not be possible to modify the standard luminaire to meet the full Cutoff classification.

In their "Advanced Lighting Guidelines 2003 Edition," the New Buildings Institute states, "It may be possible to reduce light pollution by using cutoff or semi-cutoff luminaires spaces further apart than full cutoff luminaires can be spaced to achieve the same uniformity.”

We intend to demonstrate that our proposed lighting design with Cutoff luminaires has less upward light pollution than a design using Full Cutoff luminaires achieving the same lighting uniformity. These two designs will be modeled using Lumen Micro or Radiance software, and the measure of upward light pollution will be the total luminous flux that trespasses the site above the height of the luminaires.

If all other requirements of the Sustainable Sites Credit 8 are met, and it can be demonstrated that our proposed design performs as well as a comparable design consisting of Full Cutoff luminaires with respect to upward light pollution, can this credit be attained?

SS

2/2/2004 - Credit Interpretation Request

• 2/23/2004 - RulingYes; if all other requirements of the Sustainable Sites Credit 8 are met, and it is demonstrated that the proposed design produces no more upward light pollution than the same design (same luminaire locations and lamping) using Full Cutoff luminaires, then the credit can be attained.

SS

Credit Interpretation Request

• The project is a four-story, 60,000 SF, speculative office building that is being submitted under LEED-CS.

• As we understand the intent, Credit SS8 - Light Pollution Reduction, aims to reduce light pollution through the control of interior lighting, exterior light distribution, and exterior lighting power density.

• Our question concerns the calculation requirements for the exterior lighting power density. We have been very diligent about reducing the overall lighting power density across the site. The site lighting has a 47% reduction of light power density as compared with the allowable light power density in ASHRAE 90.1.2004.” All of our exterior site lighting is on a photocell/master time control system that turns off all non-emergency lights at 10pm. Because of the neighboring uses, we have voluntarily eliminated all building façade lighting on the western façade, which accounts for nearly a third of the total building façade. This allows us to focus our façade lighting on the public face of the building, adjacent to walkways, parking, etc.. Based on our total façade area (including the western façade) our lighting power density meets the credit requirement of 0.1 watts/SF. ASHRAE, however, calculates the LPD for each illuminated façade. Using this methodology, our LPD is 0.16 watts/SF, which is a 20% reduction from the ASHRAE standard.

• Does this meet the intent of the credit?

SS

Draft RULING:

• The CIR is inquiring if projects can combine the lighting power densities for all building façade lighting when calculating compliance for this credit. Per the referenced ASHRAE Standard, building façades must be calculated individually and are considered non-tradable (cannot be traded between surfaces or with other exterior lighting areas.) In order to demonstrate compliance with the requirements of this credit, projects must document a minimum 50% LPD reduction from the ASHRAE Standard Allowable LPD for building façade and landscape lighting for each individual illuminated façade.

SS

Question

• A question has come up on a LEED project of mine about the lighting zone designations for SSc8. It has always been my understanding that the lighting zones we are to report are those of the surrounding property (not of the LEED project itself). Is that correct?

• Others I have spoken to have suggested that the lighting zone should be that of the project, not that of the surrounding properties.

• Furthermore, I can't find any reference to this in RP-33-99, so I wonder if you can let me know, too: does the lighting zone have to be the same on all property lines or can it change on each property boundary based on what abuts the project on that boundary?

SS

Response

• If a site borders more than one lighting zone, the Light Pollution requirements for the entire site must meet the most stringent lighting zone

• Light Trespass requirements may vary by the adjoining lighting zone– When two lighting zones meet, a line

perpendicular to the property line shall be drawn and the higher lighting zone may not encroach across this line

SS

NPD Credit 7 (WalkableStreets)

• Design street/sidewalk/pathway lighting to meet local requirements or IESNA recommendations in RP-8-00 Table 2 “Local” for street lighting and IESNA RP-33-99 Table 6 “Residential” for sidewalk lighting and for lighting of any pedestrian pathways in common areas where security might be an issue (use “Intermediate” in non residential areas). Light fixtures should not exceed 12 feet in height. The lighting design shall meet light pollution requirements in GCT Credit 20 and shall incorporate house-side shielding to minimize light trespass into adjacent residential buildings.

SS

LEED-ND review

• They decided not to incorporate your proposal on NPD Credit 7 (Walkable Streets), that would have included providing lighting of pedestrian ways as a way to earn the credit. They agreed that lighting can make areas more pedestrian-friendly, but they were worried that the proposed requirement could cause unnecessary lighting in some instances, since many walkable spaces have spillover lighting from buildings, etc. In these instances, it would be requiring them to use energy unnecessarily. In addition there was a sense that the committee wanted to focus the credit on the streetscaping items already included, and not expand it further.

• Credible scientists give us 10 years to be well on our way toward global greenhouse gas (GHG) emissions reductions in order to avoid catastrophic climate change.

• Yet there are hundreds of coal-fired power plants currently on the drawing boards in the US. Seventy-six percent (76%) of the energy produced by these plants will go to operate buildings.

Buildings are the major source of demand for energy and materials that produce by-product greenhouse gases (GHG).

Slowing the growth rate of GHG emissions and then reversing it over the next ten years is the key to keeping global warming under one degree centigrade (°C) above today's level.

It will require immediate action and a concerted global effort.

EA

• The fossil fuel reduction standard for all new buildings shall be increased to: – 60% in 2010

70% in 201580% in 202090% in 2025 Carbon-neutral in 2030 (using no fossil fuel GHG emitting energy to operate).

• These targets may be accomplished by implementing innovative sustainable design strategies, generating on-site renewable power and/or purchasing (20% maximum) renewable energy and/or certified renewable energy credits.

Blue Area

• Total area = 25’ x 90’ = 2250 sf• View window = 40sf x 5 = 200 sf• Daylight window = 24sf x 5 = 120sf

• GFview = 200/2250x0.1x.4/.4x.8 = .0071• GFday = 120/2250x0.1x.4/.7x1.4 = .0043• Total = .0114 or 1.1%

• Daylit area = 0.0114/0.02 x 2250 = 1282 sf

Red Area

• Total area = 90’ x 70’ minus conference room & restrooms = 6300 sf –(30x25) – (10x25) = 5300sf

• View window = 40sf x 10 = 400 sf• Daylight window = 24sf x 10 = 240sf

• GFview = 400/5300x0.1x.4/.4x.8 = .006• GFday = 240/5300x0.1x.4/.7x1.4 = .0036• GFatrium = 120/5300x.5x.3/.4x1.0 = .0085• Total = 0.0181 = 1.8%

• So not all of this space is daylit. We could calculate the fractional daylit area OR we could increase the daylit area by simulating the glazing in the entry doors. This might give us enough extra GF to simulate part or all of the conference room as daylit
