     People are looking for ways to reduce their carbon footprint. Purchasing property that is

environmentally responsible is a good investment for those who are concerned about their own

health and the well-being of the earth. Based on this trend, entire districts, known as eco-communities,

are being designed with a green focus in mind. Dockside Green in Victoria, British Columbia is

one of them.

    If everything goes according to plan, Dockside Green will be a self sufficient community along

the harbour front of British Columbia's capital city. The community will be home to 2500 people

and will consist of residential, office, and retail space. Builders of Dockside Green have the

environment in mind with every choice they make. They ensure proper ventilation(通风), and

guarantee residents 100% fresh indoor air. Building materials, such as paints and wood, are natural

and non-poisonous. Eco-conscious builders use bamboo wherever possible because it grows fast

and does not require pesticides(杀虫剂) to grow.

    Energy efficiency is one of the top concerns in eco-communities, such as Dockside Green. Not

only do energy efficient appliances and light fixtures(照明设备) reduce the environmental impact

of heating and hot water, they also save residents and business owners money. Dockside Green

claims that home owners will use 55% less energy than average residents in Canada. Residents will

have individual water metres as studies show that people use around 20% less energy when they are

billed for exactly what they use. In addition, water is treated at Dockside Green and reused on site

for flushing(冲洗) toilets.

    Planners of eco-communities such as Dockside Green must take the future into account. Dockside

Green plans on reusing 90% of its construction waste. They also plan to continue using local suppliers

for all of their transport and maintenance needs. This is a great way to reduce emissions(排放).

Dockside residents will be encouraged to make use of a mini transportation system and buy into the

community's car share program. Finally, plans are in the works for a high-tech heating system that

will use renewable energy instead of fossil fuels (化石燃料).

    Dockside residents will benefit from excellent local services with high quality healthcare, shopping

and education at the heart of the community, along with excellent recreation facilities and plentiful

green open spaces. The Eco-Community will favour the use of locally-sourced goods and services;

they will be desirable places to live, promoting a tangible(看得见的) sense of civic pride, responsibility

and, as the name suggests, community.
