Green building houses

Green building houses, thanks to a personalized architecture, guarantee an absolute freedom of design. According to individual wills and needs, and by combining a careful choice of materials with a correct orientation of the building, in the planning phase it is possible to significantly influence energy efficiency, without renouncing to a good living comfort.

From the project to the “turnkey”, Elite Ecobuilding – as the only interlocutor – can deal with all the issues related to projects, construction, coordination.

Why green building? Pros and Cons

Grrenbuilding houses are on the rise but what are the reasons that make this demand grow? In today’s global debates, the theme of eco-sustainability seems to be increasingly central, a problem that requires immediate and effective solutions because the planet has time no more time: global warming causes more atmospheric events including severe and intense floods, fires, heat waves that create emergency situations in cities around the world.

In addition to the more obvious factors, there are other risk factors that in some areas of the planet generate negative consequences for the health of us all, such as air quality. Turin and its entire province, for example, due to the geographical conformation as a basin with low air circulation, often has problems with pollution from fine dust.

Who hasn’t heard of fine dust at least once?

Fine particles are one of the problems associated with air pollution, specifically PM10, which indicates liquid or solid particles measuring less than 10 micrometres in the air. Turin in 2018 was the worst city in Italy in terms of days with air quality out of the allowed PM10 limits. The reasons are different, some natural (like the stagnation of the air, the lack of rain, and the geographical conformation), but others relate to human factors. Looking at the values ​​published in the past two years by ARPA Piemonte, the regional agency for environmental protection,  in order to identify emissive sources with greater responsibility for air pollution, two complementary approaches were combined in the Regional Plan for Air Quality:

  1. the search for information on the contribution of sources to emissions (emission picture);
  2. the search for information on the contribution of sources to pollutant concentrations (source apportionment).

We can observe from these graphs that one of the two main pollutants for air quality are the heating systems in our homes. Not surprisingly, the biggest problems occur mainly in winter. This is why the topic of green building or sustainable building is important.

Our living choices should consider the environmental impact, if we want the earth to be a liveable place for us, for our children and for future generations. This is why ELITE ECOBUILDING believes that this challenge is one of its main “missions”, so as to include “eco-sustainability” in its name. We all look at the future when we make a real estate investment, because housing is still one of the safest investments. But a future must be guaranteed to our planet, just like to our children.

Green building : definition

Let’s see what green building or bio architecture mean: with these terms, we indicate the way to design in an integrated way, to build and manage a building allowing for energy saving and low environmental impact, through:

  • ⦁construction materials
  • ⦁construction method
  • ⦁heating and cooling system.

Green building houses – prices

Obviously, each project must be evaluated individually because the costs depend on many factors;  building according to the rules of green building is not cheap, it has certainly higher costs than traditional construction methods. However, this should not discourage this investment, because if we will initially have a higher cost for the construction, then savings will be seen in the long-term management of the building, in terms of lower energy cost to achieve optimal comfort and duration, without considering the health benefits.

Green building houses – turnkey prices

Prices can vary depending on the materials and might range from € 1,200 to € 2,000 per square meter.  If you choose green building prefabricated house you may cut costs a little: from around € 1,100 to € 1,800 per square meter. These are indicative prices that do not take into account numerous variables and specific constraints related to each situation.

Green building materials, ecological building materials

Elite Ecobuilding has built over the years a series of relationships with suppliers from various sectors, selecting cutting-edge products on the theme of environmental sustainability and with particular attention to the healthiness of interior spaces. Very often we are concerned with designing and building low-consumption dwellings, without considering  the level of quality of life in terms of health. Studies at European level report that the quality of the air inside the houses is on average 7/8 times more polluted than the external one and when the external one is as polluted as that of Turin, you can imagine the risks we run.

This is due to different factors: incorrect management of the house by the user, presence of pollutants in the rooms, presence of mold or parasites, and construction problems. We often do not realize that the same building materials are a source of indoor pollution, creating more or less serious pathologies for the occupants. Designing housing solutions with natural and biocompatible materials (without substances potentially harmful to our bodies) means creating healthy and safe environments.

Environmentally-friendly building materials

The ELITE ECOBUILDING group together with partners like GREEN THINK promotes research on new materials and solutions not only respectful of the environment, but also attentive to the health of the user. The issue of Hemp in construction deserves special attention: thanks to the collaboration developed with some suppliers such as EdilCanapa, we have found a sector in continuous growth and constructive solutions, with very high performances both from an energy-efficiency point of view and for the quality of the air inside the houses.

Green building construction

Green building construction in the construction method: natural ventilation, low consumption heating, water saving, prefabrication in wood,and  cooling without air conditioning are all techniques that give comfort and services, but with low energy consumption.

The sustainable building must allow exchange with the outside and renewal of natural air (mechanical ventilation should be avoided, if not strictly necessary) in order to effectively eliminate internal pollutants (odors, smoke, toxic substances). A heat recuperator, for example, avoids dispersing heat. The use of breathable construction materials, such as straw and hemp, in the construction of perimeter walls is aldo a common technique.

Ancient constructive remedies are increasingly coming back into use, in an eco-sustainable perspective.

Even simple choices, such as correct oriention of living spaces in order to capture as much light and heat as possible, can significantly reduce the energy needs of the house: the layout of the rooms and the number and size of the windows should be a good compromise between the need for natural light and the loss of energy in the building.

Another fundamental element to reduce energy waste is to isolate the internal environment from the external environment, using high inertia materials and reducing thermal bridges during construction, as well as usingphotovoltaic and thermal solar systems. Effective stratagems can be adopted not only in the heating phase, with low energy consumption, but also for cooling; unless there is an extraordinary climatic situation, a building designed according to the rules of bio-building should not need air conditioning and should ensure adequate comfort in the summer. It is advisable to choose materials with a high degree of inertia, which absorb changes in the external temperature, while the cool of the night is absorbed by the walls that will release it during the day.

The use of reversible heating systems, as in the case of underfloor heating that in summer allow the circulation of fresh water, is also common. It is also possible to use “ancient” systems like a Canadian well to cool the incoming air.

Finally, in a sustainable house it is important to save water to meet the needs of its inhabitants, domestic hot water, but also water for the use of appliances and for irrigating green spaces, favoring technologies that allow for water saving, for example by providing for the reuse of rainwater or white water for garden irrigation and recovery of heat from wastewater.

This is why ELITE ECOBUILDING believes that this challenge is one of its main “missions”, so as to include “eco-sustainability” in its name. We all look at the future when we make a real estate investment, because housing is still one of the safest investments. But a future must be guaranteed to our planet, just like to our children.
