Towards a healthy housing in portugal
As a result it is necessary to renew the indoor air properly using a ventilation system. There are many solutions to choose depending on our needs and on the climate. This can be mechanical ventilation (single flow, double flow,…) or natural ventilation (climate sinks, window openings, wind tower). Each of these technologies is detailed here.
To maintain healthy housing, it is preferable to pollute it as little as possible. Consequently it is wise to choose healthy and ecological materials, products that are free of varnish and VOCs, and suitable construction materials.
It is recommended to use distributed insulation, that’s to say a structure that already has insulating properties and does not require the addition of an insulation material. However, it is only suitable for new buildings or extensions, and not for refurbishment. For instance these include porous concrete.
If distributed insulation is not possible, we recommend to use natural and local insulation materials.
