1 Green Building Rating System LEED for Retail Commercial Interiors Version 1 October 2007 LEED for Retail for Commercial Interiors OctoberAugust

2 Leadership in Energy and Environmental Design (LEED ) Buildings fundamentally impact people s lives and the health of the planet. In the United States, buildings use one-third of our total energy, two-thirds of our electricity, one-eighth of our water, and transform land that provides valuable ecological resources. Since the LEED Green Building Rating System for New Construction was first published in 1999, it has been helping professionals across the country to improve the quality of our buildings and their impact on the environment. As the green building sector grows exponentially, more and more building professionals, owners, and operators are seeing the benefits of green building and LEED certification. Green design not only makes a positive impact on public health and the environment, it also reduces operating costs, enhances building and organizational marketability, potentially increases occupant productivity, and helps create a sustainable community. LEED fits into this market by providing rating systems that are voluntary, consensus-based, market-driven, based on accepted energy and environmental principles, and they strike a balance between established practices and emerging concepts. The LEED rating systems are developed by USGBC committees, in adherence with USGBC policies and procedures guiding the development and maintenance of rating systems. LEED-CI is only possible due to the generous volunteer efforts of many individuals, and has been in development for over 4 years. This rating system was approved by member ballot during October 2004 after considering input from the public during two comment periods. LEED-CI is one of a growing portfolio of rating system products serving specific market sectors. Rating System Product Portfolio LEED for New Construction LEED for Existing Buildings LEED for Commercial Interiors LEED for Core & Shell* LEED for Homes* LEED for Neighborhood Development* *Under development as of June 2005 LEED for Commercial Interiors The LEED-CI Rating System is applicable to tenant improvements of new or existing office space. Why Certify? While LEED Rating Systems can be useful just as tools for building professionals, there are many reasons why LEED project certification can be an asset: Be recognized for your commitment to environmental issues in your community, your organization (including stockholders), and your industry; Receive third party validation of achievement; Qualify for a growing array of state & local government initiatives; 2 U.S. Green Building Council

3 Receive marketing exposure through USGBC Web site, Greenbuild conference, case studies, and media announcements. Certification Process Project teams interested in obtaining LEED certification for their project must first register online. Registration during early phases of the project will ensure maximum potential for certification. The LEED Web site, contains important details about the certification review process, schedule and fees. The applicant project must satisfactorily document achievement of all the prerequisites and a minimum number of points. See the LEED-CI project checklist for the number of points required to achieve LEED-CI rating levels. Additional LEED Resources Visit the LEED Web site for available tools and support, such as the LEED-CI Reference Guide (essential for all LEED-CI project teams), technical support via Credit Interpretations, and training workshops.

9 Sustainable Sites SS WE EA MR EQ ID Credit 1 Site Selection 3 points may be earned for locating the tenant space in a LEED Credited Building, OR Up to a total of 3 points may be earned in 1/2-point increments if the building in which the tenant space is located meets any of the stated requirements. Two 1/2 points are needed to earn 1 point; no rounding up is permitted. In the case of exceptional performance (for example, exceeding stated thresholds) an additional 1/2 point may be achieved; however, no single requirement may earn more than 1 point. The requirements below have been gathered from other LEED Rating Systems, and are elaborated on in the LEED-CI Reference Guide. Encourage tenants to select buildings with best practices systems and employed green strategies Select a LEED Certified Building OR Locate the tenant space in a building that has in place two or more of the following characteristics at time of submittal: Option A. Brownfield Redevelopment: (½ point) A building developed on a site that has been documented (by means of an ASTM E Phase II Environmental Site Assessment) OR A building on a site that has been classified as a brownfield by a local, state or federal government agency. Effective remediation of site contamination must have been completed. Option B. Stormwater Management: Quantity Control: (½ point) CASE 1 EXISTING IMPERVIOUSNESS IS LESS THAN OR EQUAL TO 50% A stormwater management plan has been implemented on the building site that prevents the postdevelopment peak discharge rate and quantity from exceeding the pre-development peak discharge rate and quantity for the one- and two-year 24-hour design storms. OR A stormwater management plan has been implemented on the building site that protects receiving stream channels from excessive erosion by implementing a stream channel protection strategy and quantity control strategies. LEED for Retail for Commercial Interiors OctoberAugust

10 Credit 1 OR CASE 2 EXISTING IMPERVIOUSNESS IS GREATER THAN 50% A stormwater management plan has been implemented on the building site that results in a 25% decrease in the volume of stormwater runoff from the two-year 24-hour design storm. FOR PROJECTS THAT ARE PART OF A MASTER PLAN DEVELOPMENT The credit requirements may be met using a centralized approach affecting the defined project site and that is within the master plan boundary. Distributed techniques based on a watershed approach are then required. A master planning approach to storm water management and overall impervious surface management that is overall project-wide or based on the local watershed is preferred over stormwater management planning limited to one project site at a time. The master plan setting with larger boundaries and settings allows comprehensive stormwater management techniques to be applied on a larger scale and with more flexibility. This provides economies of scale and affords greater opportunities for clustering buildings, increasing natural settings, and applying distributed management techniques cost effectively. Phasing of projects may affect when a Master Plan is implemented and how the specific building(s) under consideration will be accommodated. Option C. Stormwater Management: Treatment: (½ point) A stormwater management plan has been implemented on the building site that reduces impervious cover, promotes infiltration, and captures and treats the stormwater runoff from 90% of the average annual rainfall 1 using acceptable best management practices (BMPs). BMPs used to treat runoff must be capable of removing 80% of the average annual post development total suspended solids (TSS) load based on existing monitoring reports. BMPs are considered to meet these criteria if (1) they are designed in accordance with standards and specifications from a state or local program that has adopted these performance standards, or (2) there exists in-field performance monitoring data demonstrating compliance with the criteria. Data must conform to accepted protocol (e.g., Technology Acceptance Reciprocity Partnership [TARP], Washington State Department of Ecology) for BMP monitoring. FOR PROJECTS THAT ARE PART OF A MASTER PLAN DEVELOPMENT The credit requirements may be met using a centralized approach affecting the defined project site and that is within the master plan boundary. Distributed techniques based on a watershed approach are then required. A master planning approach to storm water management and overall impervious surface management that is overall project-wide or based on the local watershed is preferred over stormwater management planning limited to one project site at a time. The master plan setting with larger boundaries and settings allows comprehensive stormwater management techniques to be applied on a larger scale and with more flexibility. This provides economies of scale and affords greater opportunities for clustering buildings, increasing natural settings, and applying distributed management techniques cost effectively. Phasing of 1 In the United States, there are three distinct climates that influence the nature and amount of rainfall occurring on an annual basis. Humid watersheds are defined as those that receive at least 40 inches of rainfall each year, Semi-arid watersheds receive between 20 and 40 inches of rainfall per year, and Arid watersheds receive less than 20 inches of rainfall per year. For this credit, 90% of the average annual rainfall is equivalent to treating the runoff from: (a) Humid Watersheds 1 inch of rainfall; (b) Semi-arid Watersheds 0.75 inches of rainfall; and (c) Arid Watersheds 0.5 inches of rainfall. 10 U.S. Green Building Council

AND FOR EXTERIOR LIGHTING Only light areas as required for safety and comfort. Do not exceed 80% of the lighting power densities for exterior areas and 50% for building facades and landscape features as defined in ASHRAE/IESNA Standard , Exterior Lighting Section, without amendments. FOR PROJECTS THAT ARE PART OF A MASTER PLAN DEVELOPMENT Develop an exterior lighting master plan that includes the project site and the surrounding buildings in a comprehensive manner addressing the safety and security issues of the entire project environment by sharing exterior lighting amenities while minimizing light pollution and energy consumption. The lighting master plan must show that it incorporates the credit requirements as well as the following: How this plan will reduce light trespass and night sky access and specific projects fit into the overall design. How safety, security, and comfort will be enhanced by the use of a master plan. All projects shall be classified under one of the following zones, as defined in IESNA RP-33, and shall follow all of the requirements for that specific zone: LZ1 Dark (Park and Rural Settings) Design exterior lighting so that all site and building mounted luminaires produce a maximum initial illuminance value no greater than 0.01 horizontal and vertical footcandles at the site boundary and beyond. Document that 0% of the total initial designed fixture lumens are emitted at an angle of 90 degrees or higher from nadir (straight down). LZ2 Low (Residential areas) Design exterior lighting so that all site and building mounted luminaires produce a maximum initial illuminance value no greater than 0.10 horizontal and vertical footcandles at the site boundary and no greater than 0.01 horizontal footcandles 10 feet beyond the site boundary. Document that no more than 2% of the total initial designed fixture lumens are emitted at an angle of 90 degrees or higher from nadir (straight down). 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. LZ3 Medium (Commercial/Industrial, High-Density Residential) Design exterior lighting so that all site and building mounted luminaires produce a maximum initial illuminance value no greater than 0.20 horizontal and vertical footcandles at the site boundary and no greater than 0.01 horizontal footcandles 15 feet beyond the site. Document that no more than 5% of the total initial designed fixture lumens are emitted at an angle of 90 degrees or higher from nadir (straight down).

Document that no more than 10% of the total initial designed site lumens are emitted at an angle of 90 degrees or higher from nadir (straight down). 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. Option G. Water Efficient Irrigation: Reduced Potable Water Consumption: (½ point) OPTION 1 Potable water consumption has been reduced for irrigation by 50% from a calculated mid-summer baseline case. Reductions shall be attributed to any combination of the following items: Plant species factor Irrigation efficiency Use of captured rainwater Use of recycled wastewater Use of water treated and conveyed by a public agency specifically for non-potable uses FOR PROJECTS THAT ARE PART OF A MASTER PLAN DEVELOPMENT If landscape irrigation for the project is part of a master plan, enter aggregate data in the Submittal Template. Submit appropriate documentation supporting the design of the rainwater collection system, the landscape design, and the extent of the supplemental temporary irrigation system. Landscaping in the larger context of the master plan provides abundant opportunity to implement solutions that require less water and for capturing rainwater or recycled water. Large developments may consider treating its buildings wastewater to standards for non-potable uses. Option H. Water Efficient Irrigation: No Potable Use or No Irrigation: (½ point in addition to prior requirement) OPTION 1 Achieve Option G and: Only captured rainwater, recycled wastewater, recycled greywater, or water treated and conveyed by a public agency specifically for non-potable uses for irrigation has been used for irrigation. OR Landscaping has been installed that does not require permanent irrigation systems. Temporary irrigation systems used for plant establishment are allowed only if removed within one year of installation. FOR PROJECTS THAT ARE PART OF A MASTER PLAN DEVELOPMENT If landscape irrigation for the project is part of a master plan, enter aggregate data in the Submittal Template. Submit appropriate documentation supporting the design of the rainwater collection system, the landscape design, and the extent of the supplemental temporary irrigation system. Landscaping in the larger context of the master plan provides abundant opportunity to implement solutions that require less water and for capturing rainwater or recycled water. Large developments may consider treating its buildings wastewater to standards for non-potable uses. LEED for Retail for Commercial Interiors OctoberAugust

A bicycle storage space is a place in which one bicycle can be locked securely. An examples is a bicycle racks, which depending on make and model will accommodate different numbers of bicycles. Lockable changing areas and showers are intended for employees. Lockable restrooms or bathroom stalls may be used for changing areas as long as they are spacious enough to allow changing comfortably. Bike maintenance programs are intended for employees. This may include coupons for yearly bike tune-ups for riding bikes to store or having supplies on site for basic self repairs (e.g. bike pump, patch kit). Bike route assistance is intended for employees and customers. An option for this includes a map identifying bike routes to the project site posted in a location on the property that is easily accessible to employees and customers, and can also be posted on online. Design the building with transportation amenities such as bicycle racks and showering/changing facilities. Option C. Low Emitting & Fuel Efficient Vehicles: (1 point) OPTION 1 Provide low-emitting and fuel-efficient vehicles for 3% of the maximum full time equivalent shift occupants AND provide preferred parking for these vehicles. OR OPTION 2 LEED for Retail for Commercial Interiors OctoberAugust

18 Credit 3 Provide preferred parking for low-emitting and fuel-efficient vehicles for 3% of the total vehicle parking capacity of the site. OR OPTION 3 Install alternative-fuel refueling stations for 3% of the total vehicle parking capacity of the site (liquid or gaseous fueling facilities must be separately ventilated or located outdoors). For the purposes of this credit, low-emitting and fuel-efficient vehicles are defined as vehicles that are either classified as Zero Emission Vehicles (ZEV) by the California Air Resources Board or have achieved a minimum green score of 40 on the American Council for an Energy Efficient Economy (ACEEE) annual vehicle rating guide. Preferred parking refers to the parking spots that are closest to the main entrance of the project (exclusive of spaces designated for handicapped) or parking passes provided at a discounted price. For employee parking, preferred parking refers to the spots that are closest to the entrance used by employees. Provide transportation amenities such as alternative fuel refueling stations. Consider sharing the costs and benefits of refueling stations with neighbors. Consider alternative fuels/low emitting vehicles for delivery fleet. Option D. Parking Capacity: (1 point) OPTION 1 Size parking capacity to meet, but not exceed, minimum local zoning requirements, AND, within the sized parking, provide preferred parking for carpools or vanpools for 5% of the total number of parking spaces provided for employees. OR OPTION 2 Provide no new parking. For projects that are part of a development for which there is no assigned parking, the number of parking spaces to be used in calculations under SSc4 is to be determined by taking the square footage of the retail project and dividing by the total square footage of the development (buildings only). This percentage is the percentage of total parking spaces to be used in calculations. For employee parking, preferred parking refers to the spots that are closest to the entrance used by employees. Consider locating in areas in which alternative transportation is widely used. 18 U.S. Green Building Council

19 Credit 3 Minimize parking lot/garage size. Consider sharing parking facilities with adjacent buildings. Consider alternatives that will limit the use of single occupancy vehicles. Option E. Delivery Service: (1 point) OPTION 1 Provide a delivery service for purchases made from the retail establishment. It is not required that the delivery service is free of charge, but the cost should not be prohibitive. Consider providing delivery service for large and bulky purchases. Work with local cab and courier service companies to provide transport of large purchases. Locate rental vehicles, such as "Load and Go Trucks" and car share vehicles on or near the site for customer use. Option F. Incentives: (1 point) Provide incentives for employees who carpool or use alternative transportation to get to work. Potential incentives may include guaranteed ride home programs, preferred parking, or transit pass subsidies. Also consider providing incentives for customers who use alternative transportation to get to the retail project. This might include discounts on purchases made or earning points toward the award of product(s). Option G. Car-Share Membership: (1 point) Provide employees a membership in a car-share program such as Zipcar or Flex Car in which (1) the contract is for at least 2 years, AND (2) preferred parking is provided for the Zipcars or Flex Cars, AND (3) it is demonstrated that these cars are capable of servicing 5% of the employees, AND (4) if the calculations and assumptions behind Zipcar or Flex Car s estimates of customers served per car are found by the certification reviewers with a margin of error that is less than 5%. The use of programs like Zipcar or Flex Car will promote the use of shared car services both for employees and customers. Having these cars in close proximity to the retail location will help to educate the community about these services. LEED for Retail for Commercial Interiors OctoberAugust

26 Prerequisite 1 Minimum Energy Performance Required Establish the minimum level of energy efficiency for the tenant space systems. Design portions of the building as covered by the tenant s scope of work to comply with ASHRAE/IESNA Standard or the local energy code, whichever is more stringent. California Title has been deemed to be more stringent than ASHRAE for LEED purposes. No demonstration of equivalency is required for project teams implementing Title However, the use of California Title 24 is only valid for projects located in California. Design the systems impacted in the tenant s scope of work to maximize energy performance. Use a computer simulation model to assess the energy performance and identify the most cost effective energy measures. Quantify energy performance as compared to the baseline building. Because lighting can be a big source of energy use for retail projects, please note the following ASHRAE lighting power densities. Also refer to ASHRAE Sections 9.5 and 9.6 in full for additional information.
