Is it warm under a bioclimatic pergola?

The perfect compromise between a veranda and an awning, the pergola has the wind in its sails! You have heard about bioclimatic pergolas. Like its traditional cousin, it protects from poor weather and provides your garden with shade. Its louvres enable it to adapt to the environment. Nevertheless, you are wondering whether it is hot under a bioclimatic pergola when the warm weather arrives. Let's take a closer look.

How warm is it under a bioclimatic pergola?

The aluminium bioclimatic pergola consists of posts that are covered by a louvred roof. In contrast to a classic pergola, the adjustable louvres, which resist wind, enable you to adapt it to the weather conditions.

A bioclimatic construction takes advantage of the sun's rays and natural air circulation in order to reduce the need for air conditioning or heating to a minimum, and thus minimise energy consumption.

When you wish to use your exterior space during rainy weather, your pergola is a cosy and sheltered refuge. The closed roof does not let a single drop through.

However, in sunny weather you have several options: 

  • the sun's rays are not too strong and you want to feel its gentle warmth on your skin. You open the adjustable louvres vertically and enjoy your place under the sun;
  • the sun's rays are intense, but there is a slight breeze under the pergola and in the garden. You can protect yourself from UV rays by completely closing the louvres so that the heat is evacuated by the sides;
  • the sun is strong, stifling. By slightly opening the louvres of your bioclimatic pergola, you create natural ventilation. In this way you cool down the ambient air. You've mastered the natural elements!

Thanks to the orientation of the louvres, you control the air circulation to avoid excessively hot temperature under your pergola. You also control the level of shade and luminosity, which protects you from excessive temperatures and sunlight.

Nothing could be easier than to control the opening of your louvres! The built-in motor is operated with a switch or a remote control. Some connected pergolas have built-in wind and rain sensors. They close automatically in rainy weather. When the sun comes out again, their artificial intelligence waits until the slats are completely dry before opening the roof again.

Is it warm under a bioclimatic pergola in winter?

A pergola is a covered space that protects from excessive sun and bad weather. So, you benefit from your garden to relax without having to worry about the weather. But did you know that you can use your new space year-round?

We agree that its probably best to avoid barbecues under the winter snow. But have you ever felt like enjoying your morning coffee on the patio when a ray of sunshine makes its appearance? Your wish is quickly replaced by the idea of freezing cold.

Modern pergolas are equipped with numerous options that will immediately transform your garden into a corner of paradise.  They enable you to get the maximum benefit of all its advantages. LED lighting extends evenings outdoors. Thanks to misting systems, the cooling effects of natural ventilation are enhanced. And for your morning coffee, the builders haven't forgotten the heating systems!

There are different types of heating systems available, from gas to electricity, not to mention infrared systems. Once your pergola is heated, you will prolong the summer evenings and gain a few months outdoors when everyone is already shut inside.

In order to control the elements, regulate the wind and protect yourself from bad weather, the adjustable louvres of a bioclimatic pergola can be installed parallel or perpendicular to the wall of your house. It all depends on the weather conditions of region where you live.

Of course, the aesthetics also play a role in this choice, but it is preferable to give priority to your needs. Your choice will have an impact on the way you manage the ventilation, heat and sunlight, both under the pergola and inside your house.

The installation of perpendicular slats is recommended for a wall that is exposed to the east or west. You will thus enjoy the first rays of sunshine under your pergola and inside your home as well as natural ventilation all day long.

If the supporting wall is oriented to the south or north, installing the slats in parallel to the wall will enable you to benefit from optimal management by following the sun's path. You will optimise your protection against the sun's rays while getting full enjoyment when it is less intense.

It is strongly recommended to install your bioclimatic pergola facing the south in order to benefit from a maximum amount of sunshine all day and throughout the year. Nevertheless, if southern exposure is not possible, prefer eastern or western exposure over northern exposure. Despite its adjustable slats, a pergola remains a solid and imposing construction. Oriented towards the north, both the luminosity and warmth of your home may be affected.

Managing louvre opening to decrease the temperature

The best means to avoid excessive heat under your bioclimatic pergola is to follow the path of the sun.  In general, as the louvres can open from 0° to 135° or more, you can adjust the sunlight and ventilation. And for your peace of mind without having to keep an eye on the weather all day long, you can choose to install sensors that are connected to a weather station.
