Old  Laclede Power Building

Trailnet, Inc. is reusing the Old Laclede Power Building as part of it's Confluence Greenway project using
green building design principles. To help achieve aLEED Gold rating for the reused building, Trailnet and the
St. Louis Development Corporation utilized their Green Buildings on Brownfields Pilot support to retain the
services of a local engineering firm with LEED-certified engineers to study the feasibility of constructing a
green roof. The study determined that with some modifications to the roof support structure or replacement
of the roof material, a green roof could be constructed and the collected rainwater could be used for a number
of practical applications.

Green roofs, or vegetated roof systems, may reduce heat islands in urban environments, reduce stormwater
runoff, increase the energy effectiveness of roofs, and extend the life of roofing systems. The rainwater that
is not absorbed by a green roof can be collected and put back to use on the property as gray water for uses
such  as toilet flushing or irrigation, thereby reducing stormwater discharge.  Reusing rainwater decreases
potable water costs to the building owner and reduces the strain on the region's fresh water supply. For the
Old Laclede Power Building, an existing underground vault beneath the building may be used to hold the
captured rainwater for use in gray water applications, or as a heat sink for geothermal heat pumps to heat and
cool the building with less energy.
The  building is located near the
confluence  of the Mississippi and
Missouri Rivers, and will be an integral
part  of the Confluence Greenway
Project, a 40-mile riverside park and
trail system.  When completed, the Old
Laclede Power Building will serve as a
community gathering place for tourists
and local residents, office space  for
Trailnet and the Confluence Greenway
Project, and  a trailhead for bicyclists,
rollerbladers,   joggers,   hikers,
fishermen, history enthusiasts, and
nature watchers. The building may also
be a showcase for the use of green
building principles  in adaptive reuse
projects.
