The \u201cPassive<\/em><\/strong>\u201d concept is used to describe a building\u2019s capacity to make the most of its environment\u2019s natural resources, seeking the most independent running possible, minimizing the contribution of additional energy and dependency on mechanical elements (\u201cActive Systems\u201d).[\/vc_column_text][vc_empty_space height=”50px”][\/vc_column][\/vc_row][vc_row equal_height=”yes” content_placement=”middle”][vc_column width=”1\/2″][vc_column_text css=””]<\/p>\n

During the design process it\u2019s important to bear in mind the following concepts:<\/h5>\n

\nChoice of a placement for the house that is as environmentally favourable as possible, as well as positive urban integration in keeping with the local architecture and the surrounding (countryside, village, city\u2026), prioritizing well cared for outdoor spaces and abundant vegetation (tree-covered or woodland areas, parks\u2026).<\/p>\n

2- OVERALL ASSESSMENT OF RESIDENTIAL RISK FACTORS:<\/strong>
\nNoise and noise pollution, sources of electromagnetic pollution (high tension lines, electrical substations, transformers, mobile phone or telecommunication antennas) or sources of environmental pollution (waste dumps, contaminating industries, incinerators\u2026).<\/p>\n

3- GEO-BIOLOGICAL STUDY OF THE LOCATION:<\/strong>
\nAnd especially in those spaces where we spend more time (bedrooms, places where we work or rest\u2026) avoiding areas of intense terrestrial radiation, telluric or geo-physical alterations, and crossings of geomagnetic bands, and choosing instead areas known as \u201cgood place\u201d beneficial for our health and our lives.<\/p>\n

4- ABSENCE OF ELECTRIC OR ELECTRICOMAGNETIC POLUTION INSIDE THE HOME:<\/strong>
\nAvoiding proximity to sources of electromagnetic pollution and carrying out bio-compatible electrical installations in the house (cable shielding, proper earth wiring, automatic electric deactivation systems).<\/p>\n

5- BIO-CONSTRUCTION CRITERIA:<\/strong>
\nBioclimatic design that maximizes the natural resources to weatherize the building. Thought-through choice of building systems and materials, aiming to go for those as efficient, comfortable, healthy and ecological as possible. Prioritize energy saving and the use of clean, renewal energies.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_column_text css=””]6- ECOLOGICAL AND HEALTHY MATERIALS:<\/strong>
\nChoice of materials, paints, finishes, furnishing and decorative elements that are respectful towards the environment and according to biocompatibility criteria. Materials should contribute to the inhabitants’ good health, be transpirable, with low radioactive emission and without potentially toxic chemical compounds.<\/p>\n

7- QUALITY OF THE INSIDE AIR:<\/strong>
\nKeeping a constant renewal of the air inside and a proper ionization. Avoid getting inside the house construction, decoration or cleaning elements that contain chemical substances that are potentially toxic for the health or aggressive for the environment. Choose \u201csoft chemicals\u201d. Make extensive use of plants to purify and clean the inside air.<\/p>\n

8- NATURAL LIGHT:<\/strong>
\nOrientation of the main fa\u00e7ades towards the sun, wide opening and choice of maximum efficiency artificial lighting, low energy consumption and high biological quality (full spectrum).<\/p>\n

9- OPTIMAL MANAGEMENT OF NATURAL WASTE:<\/strong>
\nAvoid producing excessive domestic wastes, with responsible consumption and selective waste separation. Responsible water management (saving, recycling and ecological purification.<\/p>\n

10- THE HOME’S RESPONSIBILITY TOWARDS LIFE, HEALTH AND THE ENVIRONMENT:<\/strong>
\nPromoting houses that are designed, built and renovated with environmental mindfulness and responsibility, being aware of how a house can have an effect on the health of those living in it, and how it can be a risk factor or have environmental impact. Trying to make homes and working spaces comply within reason with energy hygiene criteria and progressively implement bio-habitability.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
