To often their are companies exploiting the eco/green aspect. Claiming that by using their product you are reducing the impact humans have on our earth. But you really have to ask, are they doing all they can? When considering building materials for your house make sure you know what energy is used to produce those materials? What is going into the product?
It's all well and good to claim to have a sustainable home, but what are the factors?
The most important part of a sustainable home....
Its made from natural materials as a basic prerequisite. The walls are made from earth, straw, timber (plantation, not old growth), stone. Less carbon footprint, more natural.
Is solar passively designed so it uses the sun throughout the day and seasons to warm and cool the house naturally.
Has cross breeze built into its design
Uses natural methods to warm and cool your home (ceiling fans and ceiling vents)
Has insulation in the roof.
One which minimises steel, concrete and glass, as they require high energy to produce = bigger carbon footprint.
Minimises the use of medium density fibreboard (mdf), plywood, glues, pvc which include toxic chemicals.
Use double glazed windows. (unless near the coast)
Restrict off gassing and carcinogenics in your home eg. Ordinary paints, melamine in kitchens and bathrooms, minimise glues and heavily toxic products (smelly products). You breathe them in 24/7 through your lungs and skin.
Uses energy efficient power (solar hot water, fluro/ LED lights) and, water efficient items (water tanks, water efficient fittings including drip irrigation and natives in the garden)
Uses thermal mass and insulation designs and materials, in synergy with one another and are tailored to
your climate and site.
