LIVING ARCHITECTURE
PERFORMANCE TOOL TAKES ON
OUR INDUSTRY'S ACHILLES HEEL
- PROPER MAINTENANCE
BY CHRISTIAN MAHLSTEDT, PRESIDENT, GINGKO SUSTAINABILITY

T

he lack of proper maintenance in the green roof and wall industry is our
Achilles heel - otherwise fantastically designed and executed projects can,
within a few weeks in the case of green walls and a few years with green
roofs, go significantly off the rails. Plants die or fail to thrive, weedy plants
move in, drainage systems become clogged and growing media washes away.
Often when we are called in to rescue projects, it's when the plants are either
dead, or dying from a wide variety of causes.
Some of the primary maintenance challenges we face as an industry, based
on our extensive experience, include the following:
* Having a knowledgeable contractor on the job who can perform the required
maintenance, and in the case of green roofs on new buildings, often repair
the damage to the green roof by other trades who are working to complete
the building. Advanced Green Roof Maintenance is a half day course we have
helped to develop that is now available online at www.greenroofs.org
* Having owners that know what the maintenance requirements are for a project, and who have documentation about the green roof and wall. Worst case
scenario is that we've been called to buildings where, believe it or not, the
facilities manager wasn't even aware of all the green roofs that they had on
their building.
* Having owners that have set aside a sufficient budget for the ongoing maintenance of the project. Often, for many projects, there is a lack of communication between the capital side of an organization and its operations side,
resulting in the building of projects for which no maintenance budget has
been allocated. When initial short-term warranty periods run out in a year
or two, these projects are often left on their own and can begin to fail. Good
design should include the develop and pricing of a maintenance plan.
* Having contractors keep good records of the work that has been done, the
problems fixed, and the changes made, is extremely useful to building owners
who may wish to contract out future maintenance work to different teams.
Information about the design, installation and maintenance of green roofs
and walls should be kept by the building owners.

LIVING ARCHITECTURE MONITOR / SUMMER 2018 / 34

Five years in the making, the Living Architecture Performance Tool (LAPT) is a
voluntary performance standard for green
roofs and/or green walls launched in April.
It is to green roofs and walls, what LEED is
to green buildings. There are 110 points that
can be earned across eight different areas of
performance including stormwater retention and even biophilic design. Providing
documentation of a five-year maintenance
contract, a detailed maintenance plan and a
budget, is a prerequisite for earning project
certification. The LAPT is in pilot project
phase and the Green Infrastructure Foundation is looking for 25 projects to become certified over the next year or so. To download
the LAPT go to www.greeninfrastructurefoundation.org. If widely adopted, building
owners will have a greater level of certainty
over the maintenance of their projects and
policy makers will have another tool to ensure that these projects performance as designed over the long term.

Christian Mahlstedt is the Treasurer of GRHC,
President of Gingko Sustainability which maintains more than 200 green roof and wall projects in the Toronto Area and works in the U.S.
through Stormwater Capture Co.
