Build for home now

Basic featuresThere are different aspects that make a house a green building, such as: Energy preservationA green house should have a mechanism to reduce the use of energy. Windows having a high efficiency and a good thermal insulation system can be used to reduce energy waste. For instance, you can use sunlight to light your office during the day without using hydro electric power bulbs. Alternatively, you can use a solar panel to light your bulbs. Using hydro electric power in this case is not being green. When it comes to outdoor lighting, high efficiency LED and induction lamps, ultra- efficient electronics and centralised intelligent control systems can be used by cities to reduce energy use up to 70 per cent. Also, by replacing incandescent traffic signals with LEDs can significantly reduce cities’ traffic signal energy use up to 90 per cent. Mr Kabandize says that embracing the outdoor living space like verandahs, patios and gazebos (outside open huts) is good idea. Water conservation Reduction of runoff water, quality improvement and minimising water use is one of the green building techniques. If you plant grass in your compound, you save a lot of run-off water contrary to one with an all concrete cast compound. Using eco-san toilets to replace flush toilets is a way of saving water. All these contribute to a green building. Materials usedGreen building materials are those materials that are considered to be renewable. For instance, bamboo due to its fast growth rate and others like straw and lumber (wood ready for use). Also, the use of recyclable material is encouraged, for instance, using timber and demolished debris. Environmental quality The quality of the air within the building should be free from volatile organic compounds hence improving the indoor air quality. This can be achieved by building and cleaning your home using materials with little or low emissions. Waste management A green building should have minimal waste from occupants. This can be attained by giving on-site solutions for excreta. For instance, garbage pits for kitchen refuse and soak pits for grey water. This helps to reduce the load on municipal treatment plants and landfills. House locationLocate your house in an area that doesn’t need tampering with the existing landscape and surrounding natural features. Also, one can plant flowers and shrubs that consume less water. Their benefits We can also ask ourselves, what are the benefits of green buildings compared to conventional structures? Low life cycle costs A study showed that, an initial increment in the first costs of approximately two per cent of green design, will give a life cycle saving of greater than 10 times the initial investment, or 20 per cent of total construction costs. Good health Since the materials used in green buildings are often natural materials, less or no emissions are given off compared to manufactured materials. This gives better health to occupants with no sicknesses and allergies. Cost effective design A well-planned integrated green design will give a saving in energy by 25-30 per cent. Design systems like building orientation, natural ventilation, natural day lighting and onsite renewable technologies reduce energy consumption hence reducing costs significantly. Better environmentBy using environmentally friendly materials and strategies for construction, environmental pollution is reduced. Also, resource sustainability is guaranteed because using eco-friendly systems like planting grass compounds, composting, recycling and afforestation are used. One of the sensitive issues about green buildings is the price. The initial cost of erecting the building is often high compared to the conventional ones but the long term running costs are always less hence saving a lot in the long run. With such benefits, setting up a green building would will be beneficial to both our economy and the environment.
