This document sets forth an initial evaluation of the LEED NC categories and projects the probability of achieveing gold or platinum levels

1. 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

2. 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.

3. 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.

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 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%.
