Sustainable architecture: the design of an ecological house


L'architecture new generation has embraced sustainability with the purpose ofto designbuildings with increased environmental awareness and create a healthy environment for both future occupants and nature. Theredesign of an ecological houseprovides basic notions that go beyond the classicalarchitecture. Indesigning an ecological housewe need to maximize the use of natural resources - be careful! "Use"And not" abuse "- limiting the use of energy-intensive technologies as much as possible.

Preliminary requirement of project of an ecological house: it must be rational and above all achievable. Here are some tips to follow during the first steps of theproject.

  • The building must be oriented in such a way as to make the most of natural lighting and ventilation.
  • When choosing the orientation it must be borne in mind that during the summer months the sun "beat "vertically while in the following winter months the rays draw a diagonal.
  • Take advantage of evergreen plants to keep the house cool in the summer and avoid creating shadows in the winter.
  • To ensure natural air recycling, create opposite openings for ventilation.
  • A roof window is very useful, especially in summer: in the evening, it allows hot air to escape.
  • The northern area (exposed to the shade) of thehomemust be designed by reducing the openings to a minimum and in the case of windows, these must be best insulated with the insertion of double glazing. In contrast, the southern area of ​​the home (more exposed to the sun) must be characterized by large windows that can be opened.

After examining the orientation, we will move on to the choice of materials, making the best relationship between the well-being of the occupants and the lowest environmental cost. The thermal coat plays an important role. Foamed polyester is a good thermal insulator, in addition, the market offers several polyurethane products that save up to 70% of energy. With the choice of materials it will be necessary to keep in mind the HVAC systems, first of all the heating which has the reputation of being the most energy-intensive of thehome.

The best heating system is the one integrated into the floor, unfortunately the radiant panels require a high initial investment. To further cut the costs of HVAC systems, a temperature control system will be required. The lighting envisaged is low energy consumption with LED units, preferably associated with a system "driver "which calculates consumption and automatically turns off the lights when the room is empty.

The electrical needs of HVAC systems and lighting can be met in part or completely with an integrated photovoltaic system, as well as a solar thermal system or, where possible, a geothermal system for water heating. Do not underestimate the importance of agreen roofto increase the aesthetic value of the home, to cushion the damage of the rain and further isolate the home.

With the orientation and the materials, the energy efficiency of the structure will be optimized but it is not just electricity savings that we must aim for, water efficiency will be of equal importance: the implementation of strategies to save water and consume more responsibly fundamental for thesustainable architecture. in this context, the most practical solutions are:

  • Rainwater collection: provides an underground storage tank in the garden, with an advanced or simple filtering and purification system.
  • Domestic water recovery: involves the implementation of treatment plants of varying complexity. The water is used again for toilets, washing or for irrigation systems.
