Mid summer and home cooling is on most peoples minds for a sustainable as possible approach to cooling you home in Portugal you could try to adhere to the principles of cooling your home passively.
Passively Cooled homes don’t need air conditioning however they do keep the air cool
and flowing without the need for an air conditioner (Hence passively cooled)
Cooling and ventilation are certainly worth considering. Living without air
conditioning in Portugal is hard to consider for many people. The alternative albeit
not widely known requires the right design, planning and house orientation, it should
be possible to live without the need for mechanical cooling by:
Extracting warm air out of the interior living spaces. Cutting down on direct sunlight
in warm months.”Tightening the exterior envelope” to keep heat from entering the home.
Utilising spaces that keep the air cool in the main living areas.
Many of these strategies work in concert with one another, and passive cooling and
ventilation are also best accomplished when they’re part of a broader approach that
sees a house being as sustainable as possible.
