Introduction An environmentally friendly house, by definition is a house that does not or does minimal damage to the environment. The house has to be built according to the climate. For example, if it’s a hot climate, you have to consider sunlight and ventilation. It uses recyclable or renewable resources, such as wood. It uses renewable energy sources, like solar panels, and uses minimal resources such as water or electricity.
Orientation and Layout The house is rectangular, with minimum wall exposure to the east and west where there is maximum sun exposure. I placed minimum windows on east and west. NorthWest East South
Orientation and Layout I placed large openings on North and South to allow cross ventilation. I used large roof overhang to shade the windows. Finally, I placed verandahs (small porches) on the East and West sides to provide shade.
Landscaping I planted grass around my house. Grass can reduce the temperature of the ground. I avoided concrete surfaces because it will heat up when exposed to sunlight. I planted large trees around my house for shading, to produce oxygen and to reduce harmful emissions. I chose the Flame of the Forest, because it is a fairly large tree. It has a considerable amount of leaves and flowers, providing extra shade
Materials Although wood might be a suitable building material for this climate, however I chose brick due to fire safety. I used sustainable and recyclable materials for the interior. The furniture and doors are made of wood from old reused furniture. For the flooring, I used marble and ceramic tiles because they are cooling materials.
Energy For energy, I used solar panels. These can be used to generate electricity, which can be used or sold to the power grid. I placed the solar panels on the east and west sides of my house, on the roof to capture maximum sunlight. It can also heat water, efficiently replacing a water heater, which saves money and energy.
Insulation and Roof The roof is insulated. The roof is quite high, since hot air rises, this reduces the indoor temperatures. Finally, there are air turbines on the roof. These allow hot air to be released outside, cooling the house. Here are small diagrams of a wind turbine. I also double-glazed the windows. Double glazing is when you put two layers of glass, acting as insulation.
Lighting and Appliances In my house, I used LED lights instead of traditional light bulbs. LED lights use less energy and give off less heat but are slightly dimmer.
Water For water supply I use rainwater. There is a pipe on the roof that gathers rainwater, and then sends it to a tank. This can be used to water the plants. I also dug a well with a hand pump.. This allows me to use water gathered in the well in case of drought.
