Construction is the process of creating a new building or structure by using natural and artificial resources in combination with manual labor. The main aim of any construction must be to protect its natural surroundings and not harm the environment by releasing harmful gasses or in any other way. With the increase in global warming, there is a strict need to address the challenges like resource depletion, climatic change, peak oil production, and pollution. Taking the seriousness of global warming and pollution into account, many new construction methods and techniques have been introduced that are environmentally friendly.
Decreasing energy consumption:
With the predictability of decreasing fossil fuels and change in climate, it is important to reduce energy consumption. Green buildings involve those construction techniques and materials which are eco-friendly. Several buildings that were constructed long ago need to be demolished due to their inability to withstand natural calamities and climatic changes. Before demolishing such buildings, most of its parts that are still new or relatively recent like furniture, floor tiles, windows, doors, furnishing, sinks, etc, are taken out by professionals so that they can be used again in new buildings. Green building construction methods not only reduces the cost of construction, but also saves natural resources.
Building Healthier Houses:
Eco-friendly construction helps in creating a better outdoor environment. Conventional building methods and materials have been associated with several health problems. Chemical toxins from solvents, paints, composite timbers, and plastic together with biological pollutants like moulds and dust mites cause problems like depression, headaches, asthma, palpitations, and serious fatigue syndrome. Green building techniques remove such problems through better ventilation design, use of non-toxic, natural materials and products, and breathable walls. This construction method also helps in strengthening the economy and supporting
An Essential Choice:
Sustainable building methods are a wise choice. The construction industry must employ eco-friendly materials and practices that decrease the impacts that can cause irreversible damage to our environment. The government also must understand the urgency required to implement green specifications in building codes and regulations. This construction method goes a great way to create and maintain an eco-friendly environment and society.
1. Location Location, Location: While buying property for yourself, take a note of couple of things that you must foresee before moving in. Firstly, avoid building west facing home. This will keep your home cool as it minimizes sun exposure. Secondly, avoid building home in environmentally sensitive locations such as earthquake or hurricane or flood prone areas. Thirdly, check if public transportation is easily available and local grocery shop is not that far away. This will help you avoid taking your own vehicle every time and will reduce your travel time.
2. Smaller is Better: A small home built with eco friendly techniques is going to have smaller environmental impact as against a large home. A house that is too large is likely to cost more to heat and cool. Try to keep the place manageable and cost effective. If you are planning to extend your family and bring in few relatives, you need to put proper resources and accommodation in place.
3. Energy Efficient Equipment: ENERGY STAR label on a piece of equipment states that particular product has been deemed as energy efficient by the Environmental Protection Agency(EPA). ENERGY STAR is becoming well known label and consumers today choose energy star appliances for their homes. These appliances offer significant cost and energy savings without compromising performance.
4. Proper Insulation: Insulation is one of the most important ting that you need to consider while building a green home. Heating and cooling account for 50% of your home’s energy consumption. Air leaks such as around windows, door and duct work is responsible for building’s heat loss. Don’t let heating and cooling of your interior spaces air go waste through improper insulation. Proper insulation will not only reduce your energy consumption but will bring down your electricity bills substantially.
5. Reduce, Reuse, Recycle: Reduce your need for buying new products that are not environment friendly. Reuse your old material such as wood floors, doors, windows in your next home. Recycled materials such as recycled glass, aluminium, recycled tile, reclaimed lumber, recycled plastic can be used in green home building.
6. Use Sustainable Building Materials: If building a green home is your goal, then using environmentally or eco-friendly products should be on your list which can reduce the impact of construction on the environment. Each and every part of your house such as roofing material, building material, cabinets, counters and insulation to your flooring should be environmentally friendly. Use products such as reclaimed lumber, recycled plastic, recycled glass or natural products such as bamboo, cork and linoleum which are made of natural, renewable materials.
7. Install Solar Panels: Solar energy is clean and renewable source of energy. Solar panels are an emerging and hot technology for people who want to utilize the natural power all around us, the sun. Solar panels may be expensive at first, but the long-term savings you can put into your pocket is a stunning example of the benefits of turning your life from black to green. The location of your house and the way you have constructed solar panels can determine how much power you can collect. By taking advantage of solar power you can bring down your energy consumption and supply excess energy, if any, to your utility company. Also, government grants, incentives and tax breaks are huge bonus to those who want to use solar power in their home.
8. Energy Star Windows: Energy efficient windows labeled as ENERGY STAR windows are new player in window market and are much more energy efficient than normal windows. The ratings for these windows determine how energy efficient they will be. The lower the rating, the more energy efficient are your windows. The energy savings provided by these windows are enough to cover the added cost per window.
9. Rainwater Harvesting Systems and Tankless Water Heaters: Install a rainwater harvesting system while building your green home to collect rainwater from roofs and then storing it in a tank. The collected water can then be used for other purposes such as toilets and sprinkler systems. Rain barrels are one of the most common methods of rainwater harvesting being used today.
With tankless water heaters, you need not wait for the water to get heated. Tankless water heaters heat only that much water that is needed as it is passed through electric coil. This gives you twin benefits. Firstly, it eliminates excess energy costs as it heats up only that much amount of water that is needed and secondly, you can get ample storage place by eliminating the hot water tank.
10. Eco-Friendly Lighting: Both LED and CFL cost more upfront but use less energy and last longer than traditional incandescent bulbs. Since they offer significant cost savings in the long run, they can be ideal for your new green home.
11. Water Conserving Fixtures: Low flow faucets, toilets, showerheads are few of the ways that you can use while building a green home to conserve water. They can cut down on your water bills cost and make your home much more environment friendly. Apart from that, consider buying washing machines and dishwashers that give you same kind of cleaning and can save water and energy.
12. Programmable Thermostat: We all know that almost 50% of our energy consumption goes towards heating and cooling of our home. The simplest way to cut down this cost and reduce electricity bill is to install programmable thermostat. Your HVAC system will work when the thermostat reaches the designated temperature. Also, a slight 3-5 % of your energy bill can be saved if you can set your thermostat 1 degree down in the winter and up by 1 degree in the summer.
13. HVAC System: Buy a high efficiency, Energy Star rated HVAC system based on the design and construction of your house that will help you save energy and money. A HVAC system needs to be properly installed so that it could perform up to its full potential. Make sure ducts are short, straight and air tight. The ducts need to be professionally tested with the goal of under 10% leakage.
14. Efficient Landscaping: Shady landscaping can protect your home from direct sunlight during the summer and allows more sunlight to reach your home through windows during the winter. Planting trees on southern and western side of your home can keep your home cooler as they will block sunlight from falling directly on your home and during the winter, when trees lose their leaves, they will allow more sunlight to reach your home.
15. Harness Geothermal Energy: Geothermal energy is known as energy from the earth. Geothermal energy requires more upfront investment but provide unlimited energy to heat and cool your home. During the winter season, geothermal heat pump uses the earth loop to extract heat from deep underground to your home’s HVAC system; in the summer season, heat is extracted from the air and moved back into the earth through loop system.
Eco-friendly, or ecological, construction is building a structure that is beneficial or non-harmful to the environment, and resource efficient. Otherwise known as green building, this type of construction is efficient in its use of local and renewable materials, and in the energy required to build it, and the energy generated while being within it.
Eco-friendly construction has developed in response to the knowledge that buildings have an often negative impact upon our environment and our natural resources. This includes transporting materials hundreds or thousands of miles, which has a negative impact in the energy required to transport them, and also in emissions of hazardous chemicals from a poorly designed building that creates, and traps them.
Many options are now available to those wishing to design and build an eco-friendly dwelling. Architects, engineers and builders worldwide are now using construction techniques that have been developed throughout human history, in response to local environmental concerns and the physical resource opportunities available, coupled with 21st century technological refinements.
These range from rammed earth construction, which involves clay-based material mixed with water and then rammed into brick or solid wall form, suitable in hot and dry climates, to straw bale houses, literally using bales of straw as the core structure.Straw is a great insulator, is a breathable material that filters the air passing through it, and contrary to expectation, is fire-resistant when compressed. And it is low cost.See our page www.sustainablebuild.co.uk/strawbale for instructions on how to build.
Other options are so-called earth ships, which use recycled car tyres filled with earth as the buildings walls, or Yurts or Gers, the semi-permanent nomadic tents of Inner Asia, that utilise local wood, wool and canvas, to literally live on, with the land.These examples can be seen as development that has a low impact upon the environment, which utilise and blend in with the local environment, and could be dismantled and moved easily.
