    • National Center for Community Renewal (NCCR) Preliminary Goals and Strategies for Leadership in Energy & Environmental Design (LEED) Green Building Rating System for New Construction & Major Renovations (LEED-NC) Version 2.2 This document describes initial thoughts for achieving scores in each of the various criteria used for ranking the NCCR project in the Green Building Rating System. As the design team, academic institutional partners, construction industry / products partners, public utility partners, granting Foundation and governmental support partners are assembled these initial thoughts will be modified or changed into final goals and strategies to guide the building design, construction and operations. The goal for NCCR is to achieve as high a ranking as reasonably possible for this project. Some possible technologies that can be incorporated will provide an initial savings or an operational savings that can make the project more economically feasible. Other technologies may not be easily justifiable in terms of economic feasibility. If this project can become a demonstration to advance technologies that show potential for commercial viability and funding can be secured, then this project will incorporate these concepts to advance the science of green building and sustainable design. The LEED categories and preliminary point targets include:  Sustainable Sites – 11 to 14 points  Water Efficiency – 3 to 5 points  Energy & Atmosphere – 8 to 14 points  Materials & Resources – 7 to 10 points  Indoor Environmental Quality – 13 to 15 points  Innovation & Design Process – 2 to 5 points The scoring levels are:  Certified – 26 to 32 points  Silver – 33 to 38 points  Gold – 39 to 51 points  Platinum – 52 or more points Based on the following initial project statements and goals for each of the criteria the likely score could range between 44 (Gold) and 63 (Platinum). Sustainable Sites (14 possible points – 11 to 14 points likely for NCCR) Erosion and Sedimentation Control – required criteria (no points)  Erosion Control and Sedimentation plans are required by the City of Shreveport for all construction projects. Buildings adjacent to the existing mh NCCR Preliminary Green Building Rating Goals & Strategies – 2.3.09 1 MHSM Architects sm
    • high rise that may be removed will require a plan to keep soil on site an out of the city storm sewer and street. This will likely be some sort of silt fencing. Site Selection – (1 point)  The NCCR project should receive 1 point in this category as the project site is in an existing central business district, renews a high-rise building that results in minimizing the footprint and the potential for sharing parking with neighboring buildings. Development Density – (1 point)  NCCR is at the center of an urban metropolitan area that has seen little commercially viable new development or renovations in over 10 years. It is a catalyst project that will result in additional investment in this urban core. The development intensity of this 200,000 s.f. project is approximately 280,000 s.f. per acre Brownfield Development – (1 point)  The site for the NCCR includes a high-rise building that has been vacant for almost 20 years largely due to extensive asbestos contamination. Developing this property reduces pressure on developing Greenfield sites.  A remediation / abatement plan has been developed for the high rise and grant funding obtained for removal.  Demolition and removal of materials should incorporate a plan for recycling construction materials such as gypsum, wire, doors, steel frames, aluminum and other products that can be sold or given to companies that use waste materials in manufacture of new products. This procedure will extend the life of waste material landfills, will reduce the extraction of natural resources used for new materials and reduce the energy required in the manufacture of new products. Alternative Transportation: Public transportation access – (1 point)  The site is located on the main street and on a city bus transit route as well as a downtown shuttle route. The main city bus transit transfer facility is approximately 1 block from the site. The privately run intra city bus station is 2 blocks from the site.  NCCR will work with the local transit authority / operator to offer incentives to employees that utilize public transit.  Many of the users of this building will arrive and depart by use of bus, taxi and airport shuttle.  SBCR operates a shuttle for transporting trainees and conference attendees during their stay. Alternative Transportation: bicycle storage and changing rooms – (1 point)  Bicycle storage and shower / changing facilities to accommodate 5% of building occupants will be incorporated into the building design as a means of reducing pollution and development impacts from automobiles. mh NCCR Preliminary Green Building Rating Goals & Strategies – 2.3.09 2 MHSM Architects sm
    • Alternative Transportation: alternative fuel vehicles– (1 point)  The public bus transit system is incorporating hybrid-fueled buses into its fleet and will add more hybrid vehicles as funding is secured. The hybrid buses can be used on routes that are used to service the NCCR.  Employees will be encouraged to live in and around downtown that will allow walking to work or bicycling.  Future NCCR shuttle purchases will include alternative fuel vehicles for transporting conference and trainee attendees that will exceed the goal of 3% of building users utilizing alternative fuel vehicles. Alternative Transportation: Parking Capacity – (1 point)  Zoning in the Shreveport Central Business District does not require that new or renovated buildings provide parking as a means of encouraging use of public transportation and shared parking facilities. If parking is provided it must meet the city parking requirements for the building use or demonstrate through a parking demand calculation the actual usage. Most users will arrive to the facility by public transport from the regional airport. Demand calculations will show significantly less parking need than other downtown office buildings and hotels.  Planned parking will expand the existing adjoining parking structure upward 2 to 3 levels. The existing parking structure is designed for vertical expansion. Reduced Site Disturbance: Protect or restore open space – (1 point if the equivalency description is accepted as described below)  This project will restore the urban fabric open space by re-establishing the pedestrian oriented streetscape and providing a safe walking environment with landscaping and amenities including storefront shops and outdoor gathering places that encourage pedestrian activity. This will include the elimination of a surface parking lot and replacement with a building that adds to the urban context.  The redevelopment of this site protects natural land areas, farmland and biodiversity of the region. Reduced Site Disturbance: Development Footprint – (1point if the equivalency description is accepted as described below)  The building complex will provide outdoor gathering places / plazas that are in excess of city requirements. Landscaping, outdoors seating and dining and public art will add to the urban environment. This regenerative project will encourage additional investment in the downtown and surrounding neighborhoods thereby conserving the natural environment and slowing Greenfield development. Stormwater Management: Rate and quantity - (1 point)  The NCCR will reduce runoff by increasing the permeable site area by 25% by the use of permeable paving surfaces and / or landscaped roof mh NCCR Preliminary Green Building Rating Goals & Strategies – 2.3.09 3 MHSM Architects sm
    • areas. The current site is 100% impermeable surfaces. Additionally stormwater will be retained on site by use of a cistern and reused for landscape irrigation. The size of this tank will likely be between 600 and 1000 cubic feet to result in a runoff reduction of greater than 50%. Consideration will be given to increasing this capacity and using this water for urinal and water closet flushing. Stormwater Management: Treatment - (1 point if utilized)  The design team will evaluate natural and mechanical system for filtering and treating runoff water to increase its utilization for onsite use such as in toilets, for plaza feature fountains, janitor sinks. This system could possibly incorporate treatment of gray water for these uses.
