The document outlines strategies for the Center for Community Renewal (CCR) to achieve high levels of energy efficiency and conservation. It aims to reduce the CCR's energy consumption by 70% compared to a baseline building through strategies like geothermal heating/cooling, solar panels, wind turbines, and more. The CCR also aims to produce more energy annually than it consumes, becoming net-zero or better. Technologies proposed include solar, wind, a fuel cell, and smart grid integration. The goals are for the CCR to serve as a model and laboratory for sustainable building practices.

CRI energy efficiency and conservation targets for the CCR are defined by
the following:
 Define standards for an ”Ever-Renewing Building”;
 Reduce CCR energy consumption by 70% over a baseline building design;
 Produce more energy than the CCR consumes annually surpassing net zero
energy;
 Optimize energy performance operations and continually commission the
building for sustained long term comfort and energy efficiency;
 Demonstrate smart grid and distributed power production on the building
side of the utility grid;

2.  Develop a hybrid alternative clean energy system specific to the Shreveport
regional climate;
 Achieve zero waste operation of the CCR;
 Monitor and improve occupant role in energy efficiency operations;
 A training and R to D Laboratory for socially, environmentally, economically
and culturally sustainable communities – a quad bottom line.
The following is a list of energy efficiency and conservation technologies that will
be part of the research, development, demonstration and deployment
collaboration that will define the Center for Community Renewal as the model for
an Ever-Renewing Building Laboratory (technologies and industry partners are
grouped by LEED categories):
 Sustainable Site Strategies and Technologies:
o Site Selection
 Reuse existing building and infill new construction on previously
developed site;
 Located in Shreveport’s Historic Central Business District;
 Brownfield Site remediated and appropriate materials recycled;
 Development Density 385,000 square feet per acre, more than
double the average density within 2 block radius;
o Alternative Transportation
 Access to 17 bus routes within a ¼ mile walking distance;
 CCR comprehensive transportation management plan to
quantify reduction in vehicle use;
 Bicycle racks / storage, lockers, showers and repair / rental
shop to serve CCR and the surrounding central business
district;
 Preferred parking for low emitting & fuel-efficient vehicles;
 Solar PV recharging parking for electric vehicles;
 Reduced parking capacity based on reduced demand;
 Parking added vertically to an existing adjacent parking
structure;
 Natural gas powered CRI shuttle bus fleet of 5;
o Site Development
 Vegetated Roof on existing building (9,000 sf);
 Hanging garden over roof plaza on new building (15,000 sf);
 .8 acre vertical urban farm above parking garage addition;
o Stormwater Design
 1200 cubic feet rainwater collection tank for non-potable uses;
 100% site irrigation from rainwater and gray water;
o Heat Island Effect
 Shaded roofs, vegetated and cool roofs to reduce HVAC roof
load by approximately 60%

3.  Water Efficiency
o 40% reduced water consumption - low flow plumbing fixtures,
eliminating evaporation from cooling towers through geothermal heat
pump, reuse of gray water and rainwater for non-potable uses (toilets /
urinals and irrigation, no domestic water irrigation);
o 20% reduction in process water – water efficient appliances, food
composting for use in urban farm, closed loop cooling system
o Monitor water consumption and integrate with energy management
 Energy and Atmosphere
o Reduce energy requirements by 60% compared to baseline 2007
ASHRAE 90.1
 Target Reductions:
 Reduce design load from baseline 20 to 8 Watts/sf (2160
KW total building) & average demand load from 9 to 3.5
Watts/sf (945 KW total building)
 Reduce peak electricity demand from 12 to 4.8 Watts/sf
 Reduce annual electricity usage from baseline of 8,100,000
kWh (2.5 kWh/sf/month) to 3,200,000 kWh (1 kWh/sf/month
or 3412 BTU/sf/month)
 Greenhouse gases: CO2 reduced 3,560 tons per year
(conservation & renewable energy strategies – 1 kWh =
.879 lbs of CO2).
 Reduce lighting power from 1.5 Watts/sf to .35 Watts/sf
through day lighting, lighting controls and lamp efficiency
 HVAC load requirement reduced from 685 peak load tons
to 270 tons cooling and 3,700,000 BTU/hr annual heating
to 1,100,000 BTU/hr
 Reduction Strategies:
 Energy Efficient work stations, computers, equipment
and appliances
o Reduce typical work station from 2500 watts to
200 watts by using laptops, task lighting, voice
over IP phone and eliminating desk top
computers, CRT’s, personal heaters & desktop
printers.
o Centralized multi-function equipment: printers, fax
and copiers
o Blade servers
o Low wall work stations (42”)
o Daylighting
 Optimize HVAC and lighting systems and integrate
building operations controls
 Continuous Commissioning to achieve long term savings

4.  Central Geothermal Heat Pump to reduce energy load
and eliminate cooling tower water consumption
o Clean Energy to Net Zero Energy plus (3,200,000 KWH projected
annual demand < 4,145,000 kWh anticipated from sources below)
 Building Integrated Solar Photovoltaic: 150,000 sf (wall and
roof) x 6 Watts/sf = 900KW (6.5 hr./day x 365 days/year)=
2,135,000 kWh annually
 Vertical Axis Wind Turbines (VAWT): 30 units (4’D x 16’ H) with
10KW generators = 300 KW capacity; Approximately 780,000
kWh annually at 9mph average wind speed
 Solar Chimney in atrium: 30 micro turbines; approximately
30,000 kWh annually
 500 KW Fuel Cell powered by bio-fuel and natural gas
producing 1,200,000 kWh annually as part of a distributed
generation system
 Combined Heat and Power (Co-Generation)
 Smart Grid technology to reduce / manage peak demand loads
 Energy Storage? / Batteries? (Demonstration of new
technologies)
 Net metering to sell excess power to utility
