Planting Design at the ASLA green roof
was developed through evaluation of the
building system microclimates. Species where
selected based on performance in each of the
varied conditions on the roof, and revised to
develop a robust and durable plant palette. .

IRRIGATION BUILDING SYSTEM.
SCHEMATIC DESIGN.
Solar Panel
The terrace irrigation and fertilization system creates a hydrologic continuum
between the terraces, lower level building landscape, and graywater system.
Irrigation water is carried to the rooftop by solar pumps and stored in an
irrigation water tank. The Terraces are irrgated by pressure created in the tank
to maximize energy conservation. The irrigation to each terrace is periodic, and
only a few terraces are irrigated at a time on a short phase irrigation cycle to
minimize the pressure required.

The daily irrigation rate is balanced to equal the evapotransipration rate.
Irrigation rate is determined by a series of substrate moisture meters linked to
the fertilization and irrigation control sytem to limit overflow and reduce reliance
on the overflow recirculation system. Any overflow is carried to the lower
landscape irrigation system along with all onsite storm water and used in a
dedicated subirrigation system and storm water retention tank. On the terraces,
irrigation with fresh water alternates as needed with fertilized water to reduce
nutrient salt accumulation in the substrate and nutrient return to the lower
landscape irrigation system.

Horticultural Building System Design
Design of the horticultural system for Atelier Jean
Nouvel’s “Green Blade” required conceptualization
of entirely new building systems that supported
the growth of 6.5 hectares of inaccessible
hydroponic garden terraces. Planting design,
details, and building systems where developed
using principles of hydroponic technology
and a California/Mediterranean plant palette.

The Basic unit Scale is derived from the
irrigation spacing required for effective drip
irrigation. The pathway grating is elevated
slightly above the surface of the hydroponic
trays allowing for cultivation of plants in the
walkway area, creating a vegetative walkway instead of a distinct pathways and hydroponic terraces in a binary condition. The
grate irrigation system pivots on the outside edge of the terrace and is detachable
adjacent to the facade, allowing for insertion of trays and access to pipes housed in
the utility gutter below. The location of the
pathway grating is flexible and may meander across the terrace at will. Plants below
the grating will be low growing and partially
cover the grate.

(2008-2009)
The DEC building functions as a local power plant
and public park, with extensive planting, accessible
terraces, and public infrastructure incorporated
into the plaza and building. Design of the green
roof, access, paths, and terraces translated Steven
Holl’s watercolors into unique tectonic systems
and a plant palette based on Canada’s Alvars.
