Sustainable architecture is developed based on different prerequisites related to respect for the environment. Of course, the use of natural materials, such as wood, that promote a lower carbon footprint in the gestation stage of projects, is a major factor. But it can be said that sustainability begins with the gaze, in the attitude to commissions.

In the end, sustainability is just that: the ability to progress without endangering the well-being of the generations to come. In the case of Le Dôme, a winery in Saint-Émilion in the Bordeaux region, designed by Foster + Partners, the desire to preserve the landscape and the sensations generated by the environment where it lies became the axis of the project.

Like just another vine

The owner of Le Dôme was sure: the vineyard in which the new winery was to be built was so beautiful that nobody would be able to compete with it in capturing the emotions of the visitor, and nor should they. Consequently, Foster’s team designed a modestly sized building with the idea that it would go unnoticed, blending into landscape.

Actually, one of the decisions that achieved this objective, so as not to diminish the quality of the installations necessary for the services inherent in a winery, was to set the building a few metres below ground. The idea of blending into the environment was achieved quite literally: Le Dôme is rooted in the vineyard, like just another vine.

A beautiful oak roof that protects the horizon

UNESCO was also clear on this: the area is Cultural Heritage of Humanity. Nothing, nor any person, may modify the landscape or its effect. Not even the balance of the horizon can be broken, marked by the small gently rolling Bordeaux hills, home to one of the most celebrated wines in the world.

With this in mind, the studio considered a 40 m roof , subtly tilted to imitate the incline of the surrounding hills. This roof is made with oak timber, specifically VIGAM, the only oak glulam in the world with the CE marking for structural use.

The elegance of the roof seen from inside, with the oak glulams drawing a beautiful circular trail, adds to the accomplishment of comfort and freedom of movement for staff and visitors, connected in an open space, with no columns in the hall. This technical challenge was overcome thanks to the structural building advantages of VIGAM.

Norman Foster, the utopian pencil

It was the Foster + Partners architecture studio, the studio created by Norman Foster in 1967, that was responsible for the design of Le Dôme. For a long time, one of the hallmarks of the British architect, a Pritzker prize-winner, has been a sustainable understanding of architecture.

Foster, now in his eighties, one of the most well-known and influential architects in the world, is still teaching new generations to design with the conviction that anything is possible. Whole 100% sustainable cities have sprung up from the utopian spirit of his architect’s pencil, such as Masdar in the United Arab Emirates, and Amaravati in India, projects yet to be made reality.

By definition, utopias are practically impossible to make reality. But if it weren’t for those who strive for them, like Norman Foster (or other contemporary architects such as Renzo Piano), what we might not have would be progress. Nor wineries with such beautiful roofs as Le Dôme.

The circular economy is a concept of consumption based on zero waste. The aim is to put into practice the opposite of “disposable”. The idea is that everything that is used (is consumed), can be reused, recycled or reconverted at the end of its useful life. Exiting the circle means failure: converting that particular product into waste.

There are more and more companies and sectors that understand that the current model of consumption is not viable for a healthy planet and, consequently, to guarantee our survival and that of other living beings. Sustainable architecture aims to seek new roads in design and construction that help to protect the environment and, at the same time, improve people’s lifestyle habits.

How can we get into the circle of sustainability?

The big question that arises in the profession is whether in practice it is possible to develop a circular economy in architecture. To respond to this, many architects are starting to focus a large part of their attention on the essential element of any project that they want to make reality: the construction materials.

We might not yet be ready to design buildings with absolutely all components able to be reused. In fact, today 54% of demolition materials are not reused, and go directly to landfill. But all indicators point to a very different way of building in the future. The route is starting to be set out clearly by society’s ecological awareness, world legislation and the scarcity of some materials.

Let’s start, as always, with wood

Wood has been helping architecture to evolve practically since its origins. Today it has become, again, an essential building material, in sustainable innovation that drives this art towards its ecological targets.

Wood is, in itself, a natural resource. Its intrinsic qualities as organic matter present it as the sustainable material par excellence: recyclable, reusable, reconvertible. Using wooden components in construction is a big first step in integrating architecture into the circular economy.

The good news is that the advantages of wood increase with its structural properties, which make it possible for many traditional products considered decorative to earn greater importance as construction components.

VIGAM: the only oak glulam beam in the world with the CE marking for structural use

Certified wood for structural use is a solution sustainable for architects who are creative and respectful of the environment. With VIGAM, the only oak glulam beam in the world with the CE marking for structural use, manufactured and distributed exclusively by GRUPO GÁMIZ, it is possible to design, for example, wooden curtain walling without the need for steel or aluminium.

With this option, professionals can achieve a lightweight façade with warmer and more attractive interiors, with the natural personality and elegance that only wood can provide.

What is most important is to have the vision that it is possible to change the world and to act on it. Many architects already do so every day, trusting wood as the most reliable building material for projects that aspire to quality, as architecture has been doing for 12,000 years.

Sustainable architecture seeks construction, urban planning and habitability responses starting with a way of living, and creating, that respects the environment. It is a philosophical attitude that nevertheless requires real resources such as environmentally-friendly techniques, clean technology and ecological construction materials.

In this regard wood is the perfect ally of committed architects. Accompanying human beings since time immemorial, its natural beauty complements its properties as an ecological, recyclable and sustainable material.

Wood stores CO2 that is not released into the atmosphere

CO2 or carbon dioxide is a natural gas present on the planet and necessary for most living beings. Nevertheless, its extraordinary growth due to the use of fossil fuels is responsible for global warming and the greenhouse effect. What happens is that large amounts of CO2 displace the oxygen.

Wood, and the products manufactured with this material, protect our atmosphere as they are able to lock the CO2 inside, “imprisoning” the gas and, therefore, not releasing into the air.

Experts assure that building a house with wood as the basic building material prevents the emission of up to 60 tonnes of CO2 for every 100 m2.

A natural material that protects the environment from its production

At the same time, the process necessary to produce wood as a building material needs a minimal amount of energy, as wood is a natural material. Manufacturing cement, steel or aluminium, for example, entails a huge energy cost, far from the energy recommendations that protect the planet and promote sustainability.

Finally, wood is an ecological building material that acts as natural thermal and acoustic insulation, so many buildings made using wood products do not require investment, or the use of non-sustainable materials, to achieve this comfort.

Certified sustainable wood

This drive for respect for the environment must have rigorous certification. Wood products that ensure the sustainability, survival and repopulation of forests and their care in the most honest and fair way possible are essential to be sure that the wood products used protect the planet.

In this regard, at GRUPO GÁMIZ we have the most important sustainable certifications, such as PEFC, FSC and EPD.

The CE marking, wood as the structural alternative to other non-sustainable materials

At GRUPO GÁMIZ we manufacture VIGAM, the only oak glulam beam in the world with the CE marking for structural use. This certification makes it possible to use our glulam beams to design sustainable structures with the beauty of oak.

For example, many architects are currently opting for wooden curtain walling. With VIGAM the beautiful, ecological lightweight façade is a reality present in projects that seek the elegance and personality of wood.

Without doubt, wood is the sustainable material par excellence, and an essential resource for sustainable architects, who already have access to structural, sustainable and beautiful alternatives, beyond concrete, steel and aluminium.

Architecture and construction are two of the pillars that are moving the world towards sustainability and common sense. This can be seen in the multiple concepts that are springing up as a response to a society that is ever more committed to the environment: buildings with almost no energy consumption (ECCN), bioconstruction, zero-energy buildings, sustainable architecture, green architecture, bioclimatic architecture, organic architecture…

One of these concepts is the Passivhaus standard. Emerging in 1988 in Germany (Passivhaus means “passive house” in German), it has been moving from theory to practice as society’s awareness and science and technology have smoothed its way. In essence, the purpose of this building model is to obtain comfort in the home by monitoring certain basic principles.

In terms of figures, Passivhaus seeks to reduce the energy consumption of buildings by around 70% with respect to those constructed with conventional building standards.

Passive House

What is Passivhaus in 5 key points?

The Passivhaus housing building standard has five fundamental aspects, that have to work together:

1. High level of insulation in walls and roofs
2. Absence of heat bridging
3. Hermetic enclosure
4. High performance windows
5. Efficient ventilation systems

Taking this into account, and although in the Passivhaus concept does not prioritise any material, it is logical that one of the most requested construction materials in this standard, and with the best prospects for the future, is that which has been contributing to energy efficiency and sustainable construction for centuries even when these two concepts were still light years away: wood.

Wood reduces energy consumption from minute zero

If the objective of Passivhaus is to reduce the high energy consumption of conventional construction, what better contribution than doing so from the start. Wood is a material that barely generates CO2 emissions during its production. Nothing like the environmental impact that other construction materials generate such as steel, concrete, lime or mortar.

In addition to constituting a sustainable solution from the start, wood suits practically every single one of the key points of Passivhaus: it is an excellent natural thermal insulator that helps eliminate heat bridging.

At the same time, wood is hygroscopic, which enables it to regulate the air quality and temperature: it absorbs the environmental humidity in winter and distributes it in summer. Comfort is assured naturally.

And the best is still to come: wood certified for structural use

At GRUPO GÁMIZ we are the designer and manufacturer of VIGAM, the only oak glulam beam in the world with the CE marking for structural use. This means that we are not just talking about decoration and interior design, but also resistance, function and structural use. 

And, of course, we are talking about beauty, quality, warmth, sensations of being at one with nature. Design, creativity and sustainability. Thanks to VIGAM, architects do not have to renounce anything in their projects: if they want wood, now beautiful, sustainable and functional solutions are possible.

For example, with VIGAM it is possible to build wooden curtain walling without using non-sustainable or cold materials such as steel or aluminium.
