Case Study Background:

The South East False Creek , is a mixed use Development project that is intended to be a leading model of sustainable development. It is located on the post-industrial waterfront lands of Vancouver,Canada.

The first phase of the project was completed for the 2010 Winter Olympics and Paralympics.

The project features efficient energy solutions , high performance green buildings and easy transit access.

Rainwater Management System:

LINK:

Rainwater management is part of an integrated resource management system with functional ecological cycles.

This design intent is an example of mimicking natural systems and working with the native ecology of place and not against it.

Benefits:

Water-conserving low-flow fixtures have been used throughout

Potable water use is reduced by approximately 50% due to rainwater harvesting.

Rainwater harvesting also aids in groundwater replenishment. 50% coverage of green roofs(7,500 sq.m) extensive + (9,000 sqm) intensive

All the water systems are a part of a park , example the hinge park and are recreational in nature.

Also , the constructed wetland in the Hinge park, provides habitat for wildlife, and education about the water system. Water returns to the watershed cleansed from its urban toxicity.

Cost of Implementation:

Cost of implementation:  $ 344, 098*
Conventional construction cost: $264, 371*
Difference is $79, 727* or 30%  

Annual maintenance cost: $69, 462  *
Conventional maintenance cost: $71, 487*
Difference is $-2,017* or -3%

Life cycle cost: $ 2,619,945*
Conventional life cycle cost: $ 2,586,800*
Difference is $33,145* or 1%

BENEFITS: Annual $5, 532* (seems like a very low estimate for our system) or Lifetime $175, 297

*(GreenValues Calculation)

Time range of construction: 2007 – 2010 ( Phase 01 )

The Systems:

Green Roofs

LINK:

287, 000 sq ft of Green Roofs – over 50% vegetated by norms in City of Vancouver

all roofs collect water, but there are INTENSIVE green roofs:

Deeper soil (over 8 inches) to allow growth of trees

Require irrigation, which comes from collection cisterns

Most easily recognizable green building feature.

Social place

5 elements:

Root-resistant layer – a root barrier deters roots from penetrating or damaging the roof membrane

Drainage layer – drainage mats are used to remove excess water from the growing medium and channel it to drains

Filter layer – a textile material prevents fine particles from being washed out of the growing medium and impacting storm water quality

Growing medium – up to six inches in depth, the mineral-based growing medium has the basic physical, chemical and biological properties needed for plant growth requiring minimal long-term maintenance

Vegetative layer – plants that can be sustained in a very shallow growing medium

Hinge Park

LINK:

Layout both linear and meandering that is a pleasant green space but also cleans stormwater runoff before it goes into False Creek

Two levels of aquatic plantings help trap sediments and contaminants

Bioswales

As part of the SEFC Plan, the City developed a wetland for Hinge Park to treat storm water from upstream of the area (the catchment area south of the site) and from the surface runoff on the city streets within the Millennium Water site.

also collects water from streams that were paved over but still flow underground – groundwater base flow will assist in keeping the system wet even during dry periods – with an irrigation system as a final backup if needed. A pumping system also ensures good circulation.

pump installed due to public health concerns about stagnant water and breeding mosquitoes, so we installed it

 

Policy:

Years before Millennium Water was even envisioned, policy makers and officials were already in the mindset of creating a sustainable community. Some significant policies below include ” Clouds of Change”, Property Endowment Fund, and “Visions, Tools and Targets”. In the link you will be able to read more in-depth information about each policy decision and how Millennium Water came to be.

Another policy in place was the SEFC Policy Statement that pushed the boundaries of general planning practice. The 15 principles are below and if you are interested in knowing more follow my link.

Implications:

Unfortunately, Millennium Water was filed for bankruptcy. “SEFC Properties Inc., the Vancouver Olympic Village developer, is bankrupt. The company, through receiver Ernst & Young, filed March 12 for bankruptcy. An order by B.C. Supreme Court Justice Robert Sewell on April 2 set the first meeting of creditors to happen no later than June 15 and permitted E&Y to also act as the bankruptcy trustee”.

Even some of the owners of the condos were asking for refunds since the developer did not keep their promise of luxurious green apartments. If you want to read more of the financial problems with Millennium Water follow the link.
