Why are green buildings?
A green building is a building that was designed to minimize its impact on the environment. This can be achieved in different ways;
- Sustainability of construction materials
- Energy Efficiency
- Impact on the environment if the demolition of buildings
Durable materials.
Eco-building to be constructed from materials proven responsible source and, if possible, the use of renewable energy. Therefore, we must think and base materials can be replaced. Specific materials that are traditionally used as a clear stone that occurs naturally – but not quickly renewable and have a significant impact on the environment during extraction.
Natural clay bricks, but again had no apparent effect on the extraction of clay and less effect known bi-fluoride products is a series of highly reactive elements that are dangerous to humans. Choice, but many are the construction of natural wood very durable and renewable. The wood used in construction for centuries and the old wooden buildings can be found everywhere, especially in Scandinavian countries.
The use of wood in green building, not just in construction, but for internal and external walls can be sure that the envelope is truly sustainable. Discover the FSC and PEFC certification to confirm the resource.
Energy Efficiency
As energy costs rise and possible defects in the future development of eco-buildings will ensure that energy consumption can be reduced to cut costs in progress and, if possible dependence. High level of insulation is a must, “U” value of the new building should be checked to ensure that the energy loss is reduced. The values ??of “U”, usually identified in the construction elements such as windows, floors or walls of cassettes. Make sure there is no weak point. If you selected a wooden building, such as MPL (Connection Machine) and lower the “U” value of 0.16W / m² K for roofs and windows, a low potential of 1.0 W / m K, is pretty obvious.
Good natural light, has many advantages: Financial, which will reduce energy bills, however, is the most important is the personal benefit of the sun, not only to improve mood, but the general health and well-being and proven to kill germs on furniture and buildings. Green building should be an opportunity for the sun and lights on the ceiling of the tube to help increase the natural light, especially in the corridors.
Ventilation is also important in the construction of new echo. Avoid expensive cooling systems and ensure that there is sufficient passive ventilation. Simple choices such as lighting and skylights open to the control electronics can help ensure that there is good air circulation. Make a good choice of durable walls pieces of wood: wood is better able to regulate the humidity of synthetic materials and do not store any electrostatic charges. This is especially beneficial for people with allergies account for about 1:04 of the population. Do not forget – the insulation works both ways to keep warm in summer and warm in winter!
The environmental impact after the demolition
According to the life of the options for sustainable construction may vary. A wooden building MPL typically will be held in more than 80 years. Only larch cladding will last from 60 to 80 years without treatment. Well, almost all buildings are at the end of their natural life, or degradation of material progress in the development and design that makes them obsolete. You must ensure that the new green building will not be a burden for future generations.
Make sure that the materials that offer a reasonable option for recycling. Bricks and blocks can be crushed for hardcore in other real estate projects – but this usually occurs only in a larger site, otherwise, is a potential disposal site because it is costly to transport. Steel and glass can be recycled and remade, but may be only a small portion of the building. The plaster of the demolition almost always in a landfill. Wood is 100% recyclable and fuel demand is always less a growing market and it would be necessary even when the building no longer exists.
