It is quite common now to hear the word green home, especially for newly built homes. Although there is not enough space here to go into details, this article is intended to be a summary of the topic.
LEED for Homes
LEED means Leadership in Energy and Environmental Design and applies to homes that meet certain specific criteria in relation to:
(1) the actual site where the building is built;
(2) the location of the structure in relation to markets, schools, parks, and so on (called links?
(3) water efficiency (both in structure and on the website)?
(4) energy and atmosphere?
(5), awareness and education?
(6) materials and resources (what the house is built in); And
(7) The indoor environmental quality.
Sustainable Site
An example of a sustainable site is one, for example, that there requires the destruction of wetlands or removal of endangered native animals and / or plant species from their habitat (s).
In other words, a sustainable location is already there, preferably in an area has a relatively dense land use classification areas. This is an attempt to prevent further urban sprawl. It also refers to places that were once, landfills and are now reclaimed for other uses. It also refers to older homes and leveling in fact, the recycling site. also reported in areas as small as possible (see rational use of water in synecheia.Topothesies
& Couplings
Developers
LEED residential construction or green housing near to existing facilities such as schools, parks, houses of worship, entertainment, and so on.
In the real estate business these are called links. It is also believed to prevent urban sprawl and make more efficient use of existing urban and suburban infrastructure.
water efficiency
except to look pretty, lawns have no real purpose and absorb much water, which then can be put to another use. Thus, the LEED home sits on a relatively small space and grass is kept to a minimum. The current configuration consists mainly of resistant plants, native to the local environment, preferably those that can survive with a little water and livestock. then gray water of the house (eg, non-sewage sludge) remains on site and works with water landscaping.
At home alone The toilets are low-flush means that only use one to one and a half liters of water per flush, or nearly half of what older toilets model used. There are even houses with chemical toilets that use no water. Yet this requires what amounts to a storage tank to hold liquid chemicals and wastes, which must be pumped out periodically. Drinking water comes in the house passes through a filter (carbon or reverse osmosis) to remove any organic contaminants.
Instead of a large hot water heater (60 – and 80-gallons), there may be three or four smaller radiators, which are heavily insulated. It is very close to the device used to minimize heat loss in pipes from the heater to the device. Even better, the hot water comes from a solar heating system and / or takes the heat from the exhaust of the central-system HVAC.
water house of gray (see above) is part of the irrigation system in the region. The irrigation system alone does not relay on the broad emission of a fine mist of water, since it can evaporate quickly. Instead, it uses a drip system, so that each plant receives a steady drop of this water directly to the stem of the plant where it emerges from the ground. The drip system does not work on lawn;. But remember, there is no grass in the green building
Energy and Atmosphere
Whilst wind energy is not really a viable option for most homeowners, solar energy and air-exhaust is (see above). LEED homes will stay connected the local electric grid, but use of these houses of electricity more efficiently (for above reasons). The use of solar energy: all the hot water in the house comes from non-electric sources, thus leading to reduced use of fossil fuels. The same is true with exhaust HVAC for heating water. There will be no net savings, if builders and homeowners use this waste of resources as an alternative energy source for heating water.
Awareness and Education
Architects and civil engineers are now studying green construction methods as part of their college education, both undergraduate and postgraduate. Many states incorporate Green construction methods in the classes applicants must be either home-or general-contractors, then part of the ongoing curriculum as well. The real estate brokers and appraisers have introduced a green building concepts in terms of how to use them to “sell” their homes, and in the evaluation of residential and commercial buildings. More on this last point, but after.
Another area> i-raising> and education is that by using recycled and recyclable materials as part of building green structures. As only one example of this, consider bio-based spray foam insulation. Currently one of the most popular bio-based spray foam insulation is made from soybean oil. When the contractor sprays this hardware in place that looks and behaves like a moose on your hair. Also, significantly increases the volume, with exhaustion. And bubbles are great insulators.
Because the contractor apply a liquid flowing in the slightest crevasses and recesses in walls, around electrical outlets, window frames, etc. (as opposed to fiberglass insulation). shields then as it expands, which means that it will remain in place (as opposed to blown rock wool insulation) . Since it is based on soy, is renewable, does not contain harmful chemicals, is easy to install and requires no maintenance. Even if it comes from an organic source, bugs will not eat. It loses insulating volume if wet and when dry, after the initial isolation, is not soluble in water.
Materials
and Resources
An example of green building materials the bio-based spray foam insulation. Another important innovation building material is an example of the use of recycled materials is that of tiles. Traditionally, these have been of wood, concrete, or asbestos. However, green building has now the ability to use pebbles from recycled car and truck tires, and all kinds of plastic bottles. While traditional cedar-shake roof shingles were evaluated for 10 – to 20 years (depending on climate and maintenance), those made from rubber or plastic bottles are 50-year rating and virtually no maintenance. When they are applied correctly will withstand sustained winds up to 110 miles per hour (and can become stronger, where building codes demand higher wind ratings).
And finally
Indoor Environmental Quality
Remember that “new car” smell we all love so much? Or how about the smell of a freshly painted room? Well, that’s to be a thing of the past (many – but not all – cases). The smells come from what those who study these phenomena call volatile organic compounds and volatile organic compounds. In these cases “volatile” refers to how easily escape by joining the base (a) in air. Since it is harmful for us, we human beings are not the best smelling (despite the nostalgia with which it can exercise its “new car smell”). If volatile organic compounds is present then the indoor environmental quality is poor. Green building materials are low VOC, so do not smell “new” for very long.
Some green building materials such as soy-based insulation ( above), while not specifically fungicides, it discourages the growth of mold and fungi, as are more traditional materials. With a heavy insulation green house, in certain climates, it is possible to install more or larger windows to allow more ambient light than anything else could happen. The theory is that this allows the green house to consume less power because there is less need to illuminate the interior of the house.
There is a downside to all this;
There definitely is. In the past green construction was much more expensive, both in terms of work involved, and their materials. However, costs have decreased as all developers and manufacturers have become more comfortable with the use of green materials. Many builders, developers and estate agents will swear that a green house has a higher resale value than a similar property more traditionally built. unfortunately there are no properly mounted on country level, statistical data to support this claim. Further, by making this claim, builders, developers and real estate brokers are basically saying that every green building savings that will accrue for the second and subsequent homeowners lost in the premium these buyers will pay for the green-built home. Therefore, the argument of cost reduction, not only now has statistical support to the market, the logic behind the claim of savings is not logical.
Another disadvantage is the use of organic materials. For example, the use of soy-based products. Those who grow soy beans do not care what the buyers of beans do with them. However, if a portion of the beans have shifted from consumption as food for human consumption as something else, then a fallow should be shifted production to make up for soybeans due to insulate your home is not, go to your plate. Now more land should be used to grow soy beans food consumption than was necessary before. Since the mass of Agriculture can not even get organic place, this land needs to petroleum-based fertilizers and pesticides to grow the soybeans before would not necessarily increase. As a result ,
