Bioclimatic pergola: what it is, how it works, how to choose

A bioclimatic pergola (also called a louvred pergola) is an aluminium structure, attached to the house or free-standing, roofed with movable louvres, normally adjustable, that control shade, light and ventilation and that, when closed, form a roof that channels the rain into the gutters. The name describes how it works: instead of fighting the climate it follows it, because the louvres are set according to the sun and the wind, by hand, with the remote control or through sensors. Michelessi, in Aprilia between Rome and Latina, sells and installs the bioclimatic pergolas of Gibus, KE Outdoor Design and Pratic.

It is not a traditional pergola, whose roof is a trellis or a fixed covering, and it is not a pergotenda, which is covered by a retractable fabric: a bioclimatic pergola has rigid louvres that move. As long as the sides stay open, or are closed only by movable screens, it is normally not a veranda either. The differences from a canopy, gazebo and veranda, which also matter for permits, are in the guide bioclimatic pergola or pergotenda, canopy, gazebo, veranda; fabric pergolas are on the page retractable-fabric pergolas. We do not supply wooden pergolas: the Gibus, KE and Pratic bioclimatic pergolas are made of aluminium.

A bioclimatic pergola works with a roof of aluminium louvres moved by a motor: tilted, they give shade and let the air through; closed, they keep the rain out. How it behaves depends on three parts: the louvres, the path of the water and the controls.

The louvres: shade, air and light

The louvres turn on their own axis. Nearly flat, they stop the direct sun; tilted, they let light and breeze filter through; and in the retractable models they can also gather into a stack to open up the sky. The maximum rotation angle declared by the manufacturers runs from 85° (Gibus Velvet) to 140° (Pratic Opera and Vision); in between are, for example, Pratic Sense at 110°, Gibus Movie and Kedry Neos at 115°, Gibus Varia at 120° and Kedry Prime at 135°. For the other models we read the figure on the manufacturer's data sheet.

The water: gutters and posts

With the louvres closed, the rain is collected by the gutters and carried down inside the posts to the drain: Gibus speaks of integrated downpipes, KE of gutters with a seal and downpipes in the columns (Kedry Neos), Pratic of gutters and drainage built into the posts. This is why the drain point is decided at the design stage: a pit in the ground, a terrace gully, the rainwater network.

Motor, sensors and controls

The louvres are operated with the remote control or with a smartphone application (Gibus Connect, for Gibus). The sun, rain and wind sensors of Gibus, the rain, snow and wind sensors of Pratic, and the wind, snow and rain sensors on the KE Kedry Plus can close the louvres on their own when the weather changes. LED lights and side enclosures are accessories chosen at the design stage.

The bioclimatic pergolas of Gibus, KE and Pratic are motorised: there is no hand-crank version among their models. Manual operation exists only on some fabric pergolas (for example Pratic Level) and on some awnings.

Adjustable louvres turn and stay where they are, always above you; stacking louvres, also called retractable, slide and gather into a stack, freeing the sky; some models do both.

There is no best model in absolute terms: exposure, the wind in your area, the presence of a kitchen or a pool and the side enclosures decide. The brand pages are Gibus pergolas, KE Outdoor Design pergolas and Pratic pergolas; for a comparison there is the guide Gibus, KE or Pratic: how to choose; for energy, the page photovoltaic pergolas.

A wall-mounted bioclimatic pergola is fixed to the wall of the house and rests at the front on two or more posts; a free-standing one, also called an island pergola, stands on four or six posts and goes wherever shade is needed, even far from the house. The sizes most often asked for, 3×4, 4×4 and 5×4 metres, are design examples, not a price list: the pergola is drawn to the real space. For example, a 4×4 metre module can cover a table for eight with the chairs pulled back; an outdoor kitchen along one side needs more length, settled on the drawing. Fixings, drainage and distances are on the page wall-mounted and free-standing pergolas.

Two examples of modules declared by the manufacturers, to give an order of magnitude; the full list by model is on the same page.

Gibus does not publish sizes on the manufacturer's web pages: we check them in the catalogue during the survey.

A bioclimatic pergola shelters from sun and rain, withstands wind up to the class declared by the manufacturer and, with side enclosures, can be used in the mid-seasons; it is not, however, a heated room. The figures change from model to model; we read them on the manufacturer's data sheet.

Rain. With the louvres closed, the water runs into the gutters and down the posts. In driving rain and crosswinds it can reach you from the side: this is why sliding glass walls and zip screens are added. Rain on aluminium louvres can be heard, as on any metal roof.

Wind. Wind resistance is measured under the UNI EN 13561 standard and expressed in classes. KE Outdoor Design declares, by model (the list also includes the fabric pergolas): Kedry Skylife, Kedry Prime, Kedry Plus, Keplan, Isola 2, Gennius Vega and Xtesa: class 6 declared; Kedry Neos class 5; Hydra class 3. KE puts class 6 at about 88 km/h. Gibus and Pratic do not publish the class of their bioclimatic pergolas on their web pages: we do not invent it, we ask the manufacturer for the model chosen. On the coast, salt air matters too: Gibus and Pratic declare a paint finish with a Seaside pre-treatment.

Snow and hail. KE Outdoor Design declares snow loads of up to 350 kg/m², not tied to a specific model, and offers snow sensors on the Kedry Plus; for Varia and Twist, Gibus offers the Snow melt system, which heats the louvres to prevent build-up. For hail we find no declared figure in the manufacturers' data sheets and we do not promise one.

Winter. Sliding glass and zip screens stop wind and cold on mild days, but glass walls are not insulating (Pratic says so of its own) and do not turn the pergola into a room. Gibus offers heaters, KE an underfloor heating system (MORE FTA-e, declared for Kedry Skylife, Kedry Prime and Isola 3). Use and care in the cold months are in the guide bioclimatic pergola maintenance: wind, snow, winter.

The advantages of a bioclimatic pergola are adjustable shade and air, shelter from the rain and the use of the garden or terrace for more months; the drawbacks are the checks on permits and condominium rules, the noise of rain on the louvres, the upkeep of the moving parts and a cost that grows with size and accessories.

Advantages

• Shade and ventilation can be adjusted through the day, by hand or automatically.
• With the louvres closed it is a cover that channels the rain without closing the space.
• The structure is painted aluminium, with a Seaside pre-treatment declared by Gibus and Pratic for marine climates.
• It may count as a solar shading device eligible for tax deductions, if it meets the requirements.

Drawbacks

• It is not a room: it does not insulate against the cold.
• Driving rain on the louvres can be heard.
• The municipal regulations, landscape restrictions and condominium rules must be checked before ordering.
• Motors, seals and drains need regular cleaning and checks.
• The cost depends on the design: quotes need to be compared on the same basis.

In many cases a bioclimatic pergola counts as free building activity (edilizia libera: art. 6, letter b-ter, of the Consolidated Building Act, introduced by the Salva Casa decree, Decree-Law 69/2024) if the roof is movable, the structure is attached or annexed to the house and no permanently enclosed space is created. Municipal regulations, landscape restrictions and condominium rules still have to be checked, and a pergola permanently closed on all sides must be checked with the municipality. We tell you at the design stage, before you order; the full conditions are in the guide permits for pergolas in Italy and, for terraces, in the one on a pergola on a condominium terrace.

The price of a bioclimatic pergola depends on five items, which is why we do not give a price per square metre, since it would compare different pergolas:

1. Structure and roof: type of louvres, size, colour of the paint finish.
2. Installation and anchoring: wall-mounted or island, terrace or garden, load-bearing capacity of the slab.
3. Water management: position of the downpipes and the drain.
4. Motors and accessories: sensors, lights, side enclosures, heaters.
5. Technical costs and service: design, paperwork, after-sales service.

Always compare two quotes on the same drawing, with the same model and the same accessories: we explain this in how much does a bioclimatic pergola cost. A pergola may count as a solar shading device eligible for tax deductions if it meets the requirements set by ENEA; this is not automatic, and the rules with dates and sources are in the guide tax deductions for awnings and pergolas in Italy.

A bioclimatic pergola over an outdoor kitchen shades the worktop and shelters whoever is cooking from the rain, but it works well only if it is born in the same drawing as the kitchen, the paving and the pool. This is our strength: Michelessi has worked stone since 1976, and the same team that lays the worktop in granite, quartzite, sintered stone or marble also installs the pergola.

In the design we settle the levels together: the posts do not fall in front of the sink, the barbecue or oven in refractory stone sits under the louvres at the safety distance the design requires, the water drain runs down the post furthest from the fire and the anchor plates stay under the stone paving. Our outdoor kitchens are made of refractory stone, steel or treated wood.

The kitchen is presented as outdoor furniture and, if the pergola is closed on all sides, it is discussed with the municipal technician; the solutions are on the page outdoor kitchen under a pergola.

We start with the survey and the 3D design, with pergola, kitchen and paving in the same drawing, and finish with installation by our own team: the process is described in bespoke pergolas: survey, design, installation, the department in bioclimatic pergolas, awnings and bespoke covers. We work across Lazio: in Rome, in Latina, along the Pontina road, between Aprilia, Pomezia and Ardea, in Anzio and Nettuno, in the Castelli Romani, in Frosinone and on the Lazio coast.

1. Look at where the shade is needed
   If the space touches the house (terrace, porch, kitchen door) the form is the wall-mounted pergola; if shade is needed in the garden, by the pool or over the parking space, the free-standing one. Note the approximate size, for example 3×4 or 4×4 metres.
2. Choose the type of louvres
   Adjustable louvres if you want an ever-present roof that controls light and air; stacking louvres, or both, if you want to be able to open the sky completely.
3. Think about rain, wind and the seasons
   Ask for the wind resistance class of the model, the sensors and the side enclosures (zip screens, glass walls) you need in the mid-seasons.
4. Check permits, condominium rules and distances
   Municipal regulations, landscape restrictions, condominium rules and distances from neighbours must be checked before ordering: we check them for you at the design stage.
5. Ask for the 3D design and compare on the same drawing
   Have the pergola, any kitchen and the paving shown in the same project and compare quotes with the same model and the same accessories.
