Glossary
Assembly : the component structure of a built enclosure or structure. The living
roof assembly is comprised of several layers, including vegetation, growing
medium, insulation, drainage layer, water retention mat (optional), ventilation
layer (optional) and waterprooing membrane. The assembly can be site-
assembled or installed using pre-fabricated integrated layers.
Best management practice (BMP) : in urban stormwater management, BMPs
are techniques used to mitigate surface runoff and its associated pollutants
from developed catchments. BMPs may include structural (built) or non-
structural practices (e.g., conservation zones or restrictions on fertilizer appli-
cation). This term is often used synonymously with the term stormwater
control measure (SCM) or SUDS (sustainable urban drainage systems);
however the latter speciically are reserved for built, engineered devices.
Building Services Planner/Building Facilities Manager : The professional who
coordinates and manages the maintenance of a building's equipment, systems
and general services.
Code consultant : a design professional, typically holding a background in
architecture but possessing detailed knowledge of local building codes,
who advises a project design team on the particulars of code-related issues.
These issues relate primarily to life-safety, including general hazard preven-
tion and safety measures in the event of a ire, earthquake or lood. While
involvement of a code consultant is not mandatory in many jurisdictions, it
is often recommended to facilitate a seamless design approval process by a
city.
Combined sewer : sewers intended to carry sanitary sewerage and stormwater
runoff through the same pipes to a municipal wastewater treatment plant.
Combined sewer overlow (CSO) : the discharge of untreated runoff and raw
sanitary sewerage into receiving environments when lows exceed the carry-
ing capacity of the combined sewer network.
Crassulacean Acid Metabolism (CAM) : CAM is a metabolic characterization in
which plants take up CO 2 at night, to metabolize it during the day. Stomates
are closed during the day, thereby reducing plant water loss by transpiration.
This is in contrast to C3 photosynthesis, in which plants take up CO 2 during
