Materials, technologies, and buildings make a green community

Dockside Green

Synergy includes four detached buildings: a nine-storey and a six-storey residential tower with commercial units on the ground floor, and a two-storey and four-storey residential building with townhouses

Dockside Green is a 120,000 m2 multi-phase, mixed use development on a brownfield site in Victoria. The site is close to the city centre and connected to it by bus and ferry.  Once complete the development will total 26 buildings and include residential, live/work studios, a hotel, retail, office, light industrial uses, and numerous public amenities.
Key principles that were established at the onset of the project included: the importance of an economically viable solution to soils remediation, the strategy of a mixed use or ‘village’ concept, the realization that a project  of this scale could support its own sewage treatment plant and co-generation energy plant, the development of a major site water management strategy.
The first phase of the project, called Synergy, completed in March 2008, is the highest-scoring LEED® Platinum Certified project on record. It totals 16,600 square metres and includes four detached buildings constructed over a common underground parking structure: two residential towers of nine and six storeys respectively,  with small  commercial units on the ground floors; a two-storey townhouse building; and a four-storey residential building. The site is bound by Tyee Road on the west; Harbour Road on the north; a greenway and creek on the east; and future development on the south.
When all phases are complete, the Dockside Green development will be organized around a central greenway running parallel to the shoreline. Made up of a series of water ponds and bioswales, the greenway is a key feature in the project’s water management system. Site storm water flows from the buildings and ground level concourses to the greenway where, along with treated black water from the on-site Waste Water Treatment Facility, it is filtered for reuse as grey water for flushing toilets and irrigation. This greenway also enhances the community’s livability by providing significant public open space.
Dockside Green features an integrated district energy system that ensures the development will be greenhouse gas neutral, while also providing the opportunity for the project to become a net-energy provider. The system includes a biomass gasification plant that converts locally-sourced wood waste into a clean burning gas to produce heat and hot water. This facility not only provides an environmentally responsible way of dealing with local sawmill and construction site waste, but also creates employment opportunities and  offers residents the prospect of stabilized energy prices over the long term.
Due to the high percentage of its power derived from hydroelectricity, British Columbia’s electrical supply is projected to be carbon neutral by 2017. In the meantime, Dockside’s biomass gasification system, along with the purchase of green power certificates, has rendered the project carbon neutral for the next two years. Surplus carbon neutral heat will be sold to neighbouring buildings, making Dockside Green a net energy generator so exceeding the standards set out in the 2030 Challenge.
In order to finance the cost of the district wastewater facility and district energy system, two separate contracts were awarded creating private partner service providers so as to mitigate the first costs of these large infrastructure projects. Currently the project is gaining revenue by treating the City of Victoria’s raw sewage in the development’s on site wastewater facility, and will be also aiming to generate revenue by selling heat from the district energy system beginning in March of 2009.
The total upfront cost to the developer was about $1/m2 but when one factors: value of increased site density permitted by the municipality; value of reduced time in achieving approvals; value of sales premium for green features; value of increased sales velocity; value of reduced condo fees, the actual up front premium for this LEED Platinum project with 63 credits was effectively zero.
Synergy’s many other sustainable features include: an extensive water recovery treatment strategy that is calculated to reduce the demand for potable water by more than 8 million litres annually; rooftop gardens; a car co-op with Smart Car; and, additional energy-saving features, including Energy Star appliances, heat recovery ventilation units, Low E double
glazed windows and exterior blinds on the west and south faces of each building. All materials used in the project were specified and selected to be regional, recycled, and durable. The Canadian CSAS378 Guide for Durability was used as a design tool for the selection of all building components.
Dockside Green demonstrates clearly and comprehensively the environmental, social and economic synergies that can be realized by integrating sustainable design strategies for individual buildings with those applied at the neighbourhood or community scale.
