The Green movement is catching on in many parts of the world.This is especially true in the construction industry.Today's buzz words,which include global warming and zero emissions,are causing people to look for ways to reduce their carbon footprints.Purchasing houses that are 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 green initiatives in mind.Dockside Green in Victoria,British Columbia,Canada,is one of these communities.Its goal is to become the world's first zero emissions neighborhood.
If everything goes according to plan,Dockside Green will be a self sufficient community along the harbor front of British Columbia's capital city.The community will be home to 2,500 people and will consist of residential,office,and retail space.The plans describe a variety of environmental features,some of which are unprecedented.
Builders of Dockside Green have the environment in mind with every choice they make.They ensure proper ventilation,and guarantee residents 100% fresh indoor air.Building materials,such as paints and wood,are natural and non-toxic.Eco-conscious builders use bamboo wherever possible because it can last for a long time without breaking and does not require pesticides to grow.
Energy efficiency is one of the top priorities in Dockside Green.Not only do energy efficient appliances and light fixtures 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.Though they are sharing space in the apartment building,residents will have individual utility meters(公用事業(yè)電表).Studies show that people use approximately one fifth less energy when they are billed for exactly what they use.In addition,water is treated at Dockside Green and reused for flushing 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.Dockside residents will be encouraged to make use of a mini transit system and buy into the community's car share program.Finally,plans are under way for a high-tech heating system that will use renewable biomass instead of fossil fuels.
