House Planning Building Material Exterior Planning Built-in Efficiency Water Consumption Electrical Appliances
Ground Floor This floor consists of the foyer, the living room, the dining room, the puja room, the kitchen, the utility, one bedroom and one bathroom.
First Floor This floor consists of a family room, two bedrooms and two bathrooms. It also has a small balcony.
Roof Planning This picture shows the roof planning of the entire house. It also shows the chimney and the place where the solar water heater can be installed.
Green roofs Green roofs enhances the beautification of concrete buildings, reduces the air conditioning use in small buildings, retention and reduction of storm water runoff, reduction of smog, decrease of noise pollution and creation of ecological habitats for insects and wild birds. Urban green roof
Opt for materials made from renewable resources.eg: Wood • Consider in particular the environmental impact of a material’s production. • Reuse materials wherever possible.
A house that uses minimal operating costs includes these features: • Walls built with 14,000 mud bricks sourced and made on-site, which retain heat in winter • Wide eaves to shade the house in summer and absorb heat in winter. • Color bond roof painted off-white to reflect heat. • Roof-canopy ventilation to let rising heat out. • Solar panels for running appliances and heating water. • Two large rainwater tanks to a rooftop header tank that feeds the house by gravity. • Grey water diverter linked to garden irrigation system.
Buy recycled: • Timber: flooring, lining boards, skirting boards. Recycled timber is often of a high quality and/or a type that is no longer widely available. • Bricks: older bricks can be aesthetically pleasing and add character to the home. • Stone: attractive stone blocks, including marble, slate and sandstone, are often available for reuse. • Doors: including internal and external doors, French doors, screen doors and security doors.
Windows: from antique leadlight and stained glass to sliding aluminium models. • Fireplace: grates, surrounds and mantelpiece of marble, carved wood and cast iron. • Light fittings: from Art Deco lamps to chandeliers. Just make sure they conform to modern safety standards. • Porcelain: baths, basins, cisterns, laundry tubs – all can be given a new lease of life by re-enameling.
An optical fiber is a glass or plastic fiber that carries light along its length. In some buildings, optical fibers are used to route sunlight from the roof to other parts of the building . Optical fiber illumination is also used for decorative applications, including signs, art, and artificial Christmas trees.

Best Laid Plans • Positioning of so called ‘wet-areas’- toilets, bathroom, laundry and kitchen- close to each other has been done to minimize the length of water pipes required to reach each area. The longer the pipes, the more hot water goes cold sitting in them, the farther new hot water has to travel and the more water is wasted. • The rooms that we need to heat or cool at the same time, such as living areas or bedrooms are grouped together • Our ceilings are lower than 2.7 m because the higher the ceiling, the more difficult and costlier to heat the room.
For water heating, a solar or electric heat-pump system is opted. These are by far the most efficient systems. • Grid-linked solar panels are installed to generate electricity. • Installing a grey water diverter can divert waste water from the bath, shower or washing machine to a garden irrigation system. • We might be able to use our grey water for flushing toilets or washing clothes. • Plumbing fittings are water- efficient and the toilets are chosen with dual- flush cisterns. These items are compulsory in new homes in some areas.
Window Design • The appropriate size of windows are chosen for the orientation and climate. Large windows on the north side will maximize natural heating. But large windows on the south side may cause heat loss. • Wooden frames are attractive, provide good insulation and are eco-friendly if the timber comes from a renewable source. • Windows are made taller rather than wider. This will let more light in.
Double- glazing are considered for cold areas. It can cut heat loss by as much as 50 percent. It also helps to block outside noise. • In warm areas, insect screens are fitted over windows so that we can leave windows open and let cooling breezes in. • Louvers’, either in the form of louvered shutters, are a useful feature for warm climates.
THE FURNITURE • The furniture in the house, is made of reclaimed timber and painted with natural paints or no paint. • No trees were purposely felled for this project as for the wood, we can guarantee, it is not fresh from rainforests. • Utilizing reclaimed wood of various styles and paint of different colours ,we artistically used furniture that goes soft on the environment.
ADVANTAGES OF USING RECLAIMED WOOD • The wood itself is typically from old forest plantations, giving a higher quality timber with a denser grain. • Reclaimed timber is structurally stable. • Environment & Health • Recycling waste timber helps reduce the amount of waste being thrown into our landfill sites. • This in turn reduces the demand for hardwood timber and the destruction of natural forests and managed timber plantations.
THE PAINT • The paints, stains, thinners and waxes are made from naturally-derived raw materials including citrus peel extracts, essential oils, seed oils, tree resins, inert mineral fillers, tree and bee waxes, lead-free dryers and natural pigments. • We used these, to reduce the use of toxic substances found in other paints and to thus reduce the harm it could cause to the environment, to reduce the need to manufacture new paint like before as most raw materials are naturally occurring and thus, the manufacturing process is also environment friendly and finally the fact that it does not differ much from chemical paint in terms of appearance led us to make this decision.
Water Consumption Ready availability of clean water greatly contributes to the quality of life. But when it is available , we tend to waste it without even being aware of it. We need to be more aware of how we use water and simple things we can do to collect and conserve it.
How To Save Water • Do not wash dishes, brush teeth, wash clothes in running water. Use water from a bucket instead. • While using a washing machine make sure sure it contains a full load of clothes. The amount of energy utilized is the same. • Take brief showers or bucket bathes instead of luxurious tub baths. • Fix leaking taps. Ten drops per minute wastes about 3000 liters of water a year. • Replace or repair loose seals on your toilets and taps. • When we flush disposable items in toilets, they do not magically dissapear.They stay in other places and will still be a part of the pollution problem. Instead, throw them in proper bins.
Use a bucket and wet cloth to clean your cars, instead of a hose pipe. • Left over water in the bottles or vessels can be thrown in the pots. • When it rains collect rain water in a bucket and strain it through a cloth. We could also use this water for cleaning brass vessels , as it does not contain corrosive salts. • Defrosted water from refrigerator is excellent distilled water and can be used as battery water for the inverter. • Water used for mopping the floors could be used to water the plants if it does not have soap or a floor disinfectant like phenyl. • Install water saving devices in the toilet as each flush saves a lot of water.
TOILETS Gravity not required! Toilet can flush 6' up and more than 50' away from compost tank. Uses as little as 0.2L of water per flush. Double tank high capacity model.
The Energy Efficient Home
Our Top Ten Energy Savers • To make use of most of the sun’s warmth large windows are installed on the northern side of the house. To stay cool in summer, awnings, eaves or blinds are installed that block the high summer sun. • Our home must be well insulated. A properly insulated home can be up to 10°C warmer in winter and as much as 7° C cooler in summer. • Whenever the weather permits, we use a clothes line instead of a dryer. WE will save money and cut green house gas emissions. • One of the simplest ways to save energy is to switch off appliances at the wall when we won’t be using them for a few hours. Keeping appliances on stand-by can account for 10 per cent household electricity bill.
While using central heating and an adjustable thermostat when we try turning our heating down a fraction- we may not notice a big difference heat- wise, but we could make big savings; a reduction of 1° C can cut bills by 10 per cent. • We plugged gaps around windows and doors and any other external openings using draught excluders and weather strips. Drought proofing can cut household heat loss by up to 25 per cent in winter. • We replaced standard incandescent light bulbs with compact fluorescent bulbs (CFLs). C L Fs are more efficient, creating an equivalent light at a significantly lower wattage- a 25- watt CFLs is as bright as a 100- watt regular bulb. As a result, CFLs can last 10 times as long and use 80 per cent less energy.
Between natural gas and conventional electricity, we go with gas. Not only is natural gas normally cheaper, it produces one- third of the greenhouse gas emissions of electricity from coal-fired power stations. • Our hot water tank and pipes are properly insulated. In an average home, heating water accounts for more than one-quarter of the household energy bill; and as much as half of total water- heating costs can be due to heat loss. • We must select appliances that are both energy-efficient and the right size for our needs – a 284 liters fridge will use 20 per cent more energy than a 210 liters fridge, even if they have the same Energy Rating.
Central Heating • If we opt for central heating, we will buy a zoned system-one that lets you turn heat off and on in each room or at least different parts of the house These can easily cut down our heating costs. • The pros and cons of the main types of central heating; ducting air, hydronic, thin film and in-slab heating. Most can be fuelled by electricity, gas or LPG. • A system with a high efficiency rating is chosen. • WE make sure that the system is the right size and has the right amount of power for your home.
