ARCHITECTURE’S ROLE IN TOURISM AND CITY BRANDING_

Architecture’s role in Architecture and tourism are very closely related activities. It can be said to depend on each other. Their mutual relationship is obvious since ancient times where the architecture, as a tourist attraction, had a very important role. Temples have been built in honor of the gods, grand theaters, stadiums, the Colosseum and other monumental public buildings attracted large crowds as characteristics collected certain culture and society in which they arose. Architecture was and is an expression of lifestyle and spirit of the times certain epochs and cultures in which it arises. Many cities throughout Europe (Paris, Rome, Athens, Venice, Amsterdam and many others) are an ideal example of how the spirit of an era, an era still lives through the architecture of buildings built in this period, based its entire tourist offer and its development just on the monuments culture in the field of architecture, but also on the cultural characteristics of the society belonging to an age when architecture was created. It can be said that the architecture in this case is source of information about the history and the element that identifies the city, nation, country.

Lately there has been a major transformation. Until a few decades, historical heritage (monuments) were the basis of cultural and architectural tourism, today excellent Modern architecture has the same power of attraction, what makes cities great increase in the number of tourists and turning cities into a new tourist attraction. The example that best describes this is Dubai, known worldwide as a Middle Eastern capital of extravagance. If we look at photos from 20 years ago, and 10 years in advance can be clearly seen how the city for only 10 years, thanks to oil money, became a popular and the last few years one of the major tourist destinations in the world. However, it is well known that today oil plays a very small role in the overall revenues of the state, while tourism and trade play a most important role. This is an example of modern branding of the city by the imposing architecture.

Modern architecture is a commercial, whether it be on the premises or on the context in which it is created. The building itself is an attraction, a great advertising that its form points to the leisure facilities, but when placed in the context of the city, the region and the environment in which it is located (location, climate, relief,  cityscape) then becomes a symbol of not only the author’s work but rather the symbol of the city, region, country, society.

An ideal example is Sydney Opera House( by architect Jon Utzon) is a true example of the impact that architecture can have, not only the location at which it is generated, but also to the global culture. Location of the property affects the inspiration for the shape of the object, which visually should be a sail on the high seas. The image that was created by unique performance of shell of the object became a global landmark in Sydney, but also symbol across Australia. Surely, such a facility would be a spectacle at any location in the technological sense, but its siting in the coastal city has a specific meaning and thus the dependence of the location comes into play. Such objects of course should contribute to a better positioning of the city in the network / system of European and world cities, which has the effect of economic advancement.

 However, is this modern architecture economicaly and functionally viable?

As for the commercial component architecture and tourism, art and expressive architecture is certainly a luxury where economically successful enterprise functionality of the building deemed sufficient. For the purpose of explanation must be noted that in this case we’re talking about architectural design that is reduced to the minimum requirements set by one such a functional building. Tourist property mostly have value if they are  profitable, no get no value. Architecture costs and naturally multiplies the investment compared to the facility that is reduced to pure functionality. Already at the stage of business planning topics architecture is the first critical point and requires a professional economical budget and highly professional estimation of the location and design of products. In contrast, good or unusual architecture increases the interest of the market and, depending on the product evaluation, can give a new location, attractive appearance. This again increases demand and real price, which in turn makes for a larger commercial success than it would perhaps be achieved by conventional functional construction.

Architecture creates also new functionality, or causes by using this new functionality that all inherited and old different experiences, thus offering the possibility of tourism development of new products. From the perspective of visitors still here must not remain non-mentioned discussion ‘form follows function’ or ‘function follows form’ that just in tourism real estate and products can lead to oscillation in the evaluation of both positive and negative. Tourism and architecture never before were so closely together on the development of products such as is the case today. This again closes the circle of mutual success. Therefore, unsuccessful projects are “monsters”, built as a demonstration of a specific conceptual directions in architecture, which are successful in their intent to share certain thoughts and way of looking at architecture and urban space and there are only a sculptural, while their function transforms.

There we come to the point of sustainability, which is not just a technical problem. In order to achive success, a sustainable project must be socially sustainable as well as economically. Such a project should comunicate with its society, should attract and be inspiring, and over all mast make economic sense. Architecture in terms of tourism  is now an integral element of the planning of the city, whether it is of cultural heritage or contemporary architecture. When it comes to heritage, it is the architecture resulting in a particular context that is completely defined and therefore it is a testimony about history. In this sense, the architecture can become a brand that describes the identity of certain social or cultural groups, and linked to the cultural and educational tourism.  Although today in most cases this architecture is unfunctional and hard switching to modern forms of construction works and the city life, it must be preserved and used in the planning of sustainable development of the city just as part of the tourism industry.

Modern architecture, unlike the architecture of cultural heritage, is viewed from the aspect of entertainment and spectacle, even if we talk about function of the structure, location or shape. Unusual and controversial form that uses all the benefits of modern technology certainly attracts the attention of visitors, but this is not always enough. Location which provides the context and function that brings the economic viability and the possibility of continued use of space is also one of the important factors for the transfer of a work of architecture in the branded product. Modern cities  nowadays pay  a great attention to precisely such projects, as drivers of further development and city expansion, as well as the region, in some cases and countries. Great architecture, not only that it promotes economic and social development, but it becomes a product that markets itself as a symbol that exceeds target group and everyone’s must-see tourist destination.

STOP WALKING AND LOOK UPWARDS : THE BARCELONA PARTY WALLS CASE

Barcelona is a great  city, livable, with an exemplary urban structure and plenty of well planned and developed public spaces.  It transforms and reinvents itself, making it one of the most attractive cities in the world. Even dough much can be said about its culture, its beauty andits people, in this occasion we’ll focus on a  building component  which becomes crucial at a city scale( and world scale also). I’ll like to point out to a “small scale” constructive element which is directly related with the buildings energy performance and efficiency and thus, with the economic  impact it causes and the toll the environment is paying if we don’t considering it as fundamental. I’m referring  to each of the building(s) exterior party wall(s) , a seemingly typical  vertical architectural element, that  when multiply by thousands, can  become relevant to the city energy  performance.

As described in the exhibition ” Mitgeres Barcelona: de l’oblit al projecte”….”Party walls are those anonym city walls, which divide properties, without any real protagonism  in the external aspect of a building, which due to urban regulation changes are now exposed to our vision, in a seemingly permanent provisional state. When this happens there’s a discontinuity in the urban landscape, a fracture in the urban tissue which generates great constructive problems between the neighbors.”  Lateral walls in the Mediterranean models of compact cities, like Barcelona, are built with the intention that afterwards they will disappear when faced with a neighbor building. But sometimes this doesn’t happen, some of the causes can be summarized : Non-continuity of the urban plots, Changes in Urban -political regulations, extreme disorder,  topography, marginal urbanization and self-construction.

I drive a motorbike in Barcelona, and most of the time when I look upwards I see these exposed  or “naked” party walls everywhere, like if each one is fighting to stand before the othe one…..so questions like the following cross my mind:   ¿ why can’t this bare walls become actual facades?  ¿How much energy / heating is wasted because of their current thickness?  ¿what can  I propose as architect in order to help improve their efficiency? this among others..

 

It is said that the amount of wasted energy of a party wall is as much as double as the one lost with a conventional facade and much more of that of a building touching the other neighbors wall( a finished mediterranean model) . A preliminary number  reveals there are around   8000 party walls in Barcelona, constructed basically with a 15 cms brick layer which separates the interior with the exterior. In winter ,heating is lost,  the party wall is not efficient,  we are losing money and contaminating.It  is also not sufficient to protect from the warmth and sunshine of the summer months.  As a metaphor ,the amount of CO2 that party walls emit  due to the lack of enough insulation can be compensated with approximately 20 soccer fields full of new planted trees, this will overcome its contaminant effects in Barcelona. The CO2 emissions are between 11,2 kg/m2 -year and 36,4 kg/m2- year, we just need to multiply the exposed square meters of the  party walls to get some aprox. numbers.

Having said this, there has been much done to improve the party walls and their attractiveness, mainly from the l’Institut de Paisatge Urbà i Qualitat de vida. Actions have been taken to transform party walls into artist canvas, used for advertising to self-fund its constructive improvement or to  convert them into vertical gardens. Other campaigns such as Barcelona posat guapa  where aimed to renovate and expose the attractiveness of certain buildings and monuments around the city.Some examples of party walls interventions can be seen in “The cats wall” in carrer Xuclà 5, in “Balcons de Barcelona in Diagonal-Aragó or the party wall next to MACBA in Plaça dels Àngels , which mimetizes with  the surrounding roof-tops TV antenas in a great steel abstract intervention.Other intervention is Jardí tarradellas, a vertical green wall full of biodiversity.

On the other hand, Barcelona is blessed with plenty of Sun light which can be used as a natural source of energy. On the contrary, its pollution levels are high  and the Purity and Cleanliness of the Air quality is low. In Barcelona, the biggest contribution to the figures are a massive increase in CO2 emissions produced from an influx of personal vehicles on the roads.

Looking at the party walls previous interventions ( artistic, advertising, green walls) and faced with all the fore mentioned information, the challenge was to think a step forward and try to study a prototype which not only improves the attractiveness of the party walls exterior, but one which can produce energy, help clean the air around it and at the same time can be economic.

Inspired in Barcelona tree structures and leaves( els plataners) , and due to the technological progress in Solar PV technologies (and watt price), the prototype can be seen as a artificial PV tree, where the leaves are the solar collectors and the branches the energy distributors( emulating a photosynthesis) . The idea is that the solar energy produced by the city South facing party walls can help reduce the own building’s  electricity bill and/or be transferred to a close-by public building or any other system that requires more energy. If there’s spare electricity, it can also go to the city grid. In case the wall is not facing South, a smog-eater treatment can be applied to the prototype “Leaves” instead of using Photovoltaics. A similar approach  can be taken considering  rooftops and other urban constructive elements.Barcelona trees as inspiration

As a first step, before implementing the prototype, the wall should be provided with the correct insulation. As the wall external  finish, and in order to clean the city air around the wall, we can apply  an existing proved Paint  treatment with active principle, which allows the Nitrogen oxides that accumulate on the wall and prototype surfaces and with the help of a titanium dioxide catalizer, which activates oxigen, all the Nitrogen oxides transform into  Nitrate(NO 3-).This NO3- is cleaned with rain water.

The prototype i s planned to reduce the buildings energy demand and help improve quality of life and the environment. We have seen deaths from air pollution in some countries, we are now faced with climate change challenges, with a social and energetic agenda, with water scarcity, among others. I believe in the technical expertise of architects, but I also embrace  intuition  and imagination as a source of solving problems.

I’ll like to quote Albert Einstein:

“Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand.”

circular-economy

 

 

Cradle to cradle

When reinterpreting processes leads to success

 

When I submit these thoughts to a printing press, I am helping cut down the woods. When I pour cream in my coffee, I am helping to drain a marsh for cow to graze, and to exterminate the birds of Brasil. When I go birding or hunting in my Ford, I am devastating an oil field, and re-electing an imperialist to get me rubber. Nay more: when father more than two children I am creating an insatiable need for more printing presses, more cows, more coffee, more oil, to supply which more birds, more trees, and more flowers will either be killed or, what is just as destructive, evicted from their several environments”. These words are very actual and could be ascribed to a modern environmentalist. Unfortunately this essay was written by Aldo Leopold at the beginning of XX century. The drive to ensure that the industry could be less destructive goes back even more. Since the end of XVIII century some people understood that the only way to preserve the Earth was in the Nature itself. Because of their pessimism, against the great industrial revolution that, at that time, the human kind was facing, they were considered only caricatures. Even if their aim was good, they lacked in something: scientific basis. Was only in the 1962, when, with the publication of Silent Spring by Rachel Carson, scientific reasons were added to the cause. This book led to the banning of DDT in the US and in German, and sparked controversies about the danger of industrial chemicals.

Nowadays we face even a worse situation, this is why recycling or being “less bad” doesn’t mean we are acting in the right way, and the solution is hidden in the linear way we think and act.

When we hear the word “waste”, the first image that appears in our mind is about something not anymore useful. But depending on the point of view it can be something dismissive, a worthless material, or by another interpretation a mine of possibility, and, if not used, a lost opportunity. In nature examples of how it’s possible to use again leftovers not throwing them away, but creating a circular system, are quite a lot. The prospect exists of deriving far more value from the same resources while moving towards zero-waste ways of operating. In this perspective the most important change that we can operate is to shift from a linear, wasteful and polluting way of using resources, to a closed loop model.

A basic consideration is that the linear mode of “take, make, dispose” of the industrial processes and lifestyle that feed on them deplete a finite reserves to create products that end up in landfills or in incinerators. This reflections brought people, as Walter R.  Stahel, to re-think the industrial processes and the manufacturing way of creating things, in order to have “cradle to cradle” strategies.

With the term circular economy is meant a particular way of designing material dividing them in two big categories: in the first we find the biological nutrients, or material that are designed to re-enter in the biosphere once they have finished their life, and technical nutrients, or material with an high quality that are designed to circulate for a very long period and are not meant to enter in the biosphere.

Stahel was one of the founder of this way of thinking. He created the Product Life institute in Geneva,  a consultancy devoted to developing sustainable strategies and policies.  In his book “The performance economy” he explains how is possible through a circular economy to extend the product-life, optimizing the total life-span of goods and reducing depletion of natural resources and consequently waste. This can be seen in Nature through the life of plants. The photosynthesis turn carbon dioxide into sugar and, with the addition of other elements taken from the soil, they are capable of growing and forming the basis of most food webs. Nitrogen is fixed into the soils by other types of plants that, due their evolution, have evolved a symbiotic relationship with bacteria called rhizobium. Thanks to this, when a plant dies or is been digested by an animal or microorganism, the carbon, the nitrogen and other elements are returned to the soil. In a similar manner, water, is cycled through ecosystems and returns to the soil as rainfall. All this processes are typical examples of a circular economy where nothing is wasted, but everything is reused to return to his original status.

In general all the ecosystems are based on this. The idea of restoring the balance when it is perturbed is the base of the “circular economy” of the nature. A simple rock gets eroded by rain, wind an ice and the grit from this process flows into hollows and is distributed to lichens and other vegetal species. These extract the nutrients creating the substrate for the formation of a simple soil on which grass can grow. On this, humus, over the time, and other microorganism expand in the soil. In a short period pioneers species, plans and other primary colonisers arrive to change the aspect of the environment and establish themselves. They create the perfect ecosystem for the second colonizers that grow on top of them, changing again the environment. Below the ground another rich system of worms, insects, fungi and microorganism proliferate to reach the same aim. This succession of species continues until the balance is reached. Only through this process the life of a variety of different species is permitted. They grow on top of each other, using the “waste” or the dead parts of other organism. In nature everything is reused for another purpose, or is decomposed to his chemical formula to renter in the cycle again.

This is the crucial point that marks the big gap between our human society and the Nature. While we create simple linear systems, nature creates complex closed-loop systems that can be the base for different species to live. We use things and when they are not more useful we throw them away, while Nature creates zero-wasting systems that can adapt his behaviour if the external condition changes. Other big differences between the human way to design and the nature one are the fuel used and the use of local resource. While the former uses fossil fuel, nature uses solar energy to create all the processes that needs. Moreover all the basic necessities are satisfied locally. The resources that every animal or plant, or in general organism, need, are found locally. If this sometimes is not anymore possible they change their needs to adapt themselves to the new environment. Darwin explained this in an eloquent way: “It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is most adaptable to change.
In the struggle for survival, the fittest win out at the expense of their rivals because they succeed in adapting themselves best to their environment”.

But what is more remarkable is the way the nature society is conceived. While in biological cases there are millions of contributors to the system, no unemployment, and numerous opportunities for nature’s equivalent of entrepreneurship, in human one we have the opposite situation. Large multinationals often dominate, power resides in the hands of few people, a degree of unemployment is deemed necessary and creative entrepreneurship is limited.

Even if the displacement between humans and Nature is not so easy to fill up, some efforts to mimicking the Nature’s systems are made by some people all around the world. In Denmark has been created an industrial ecosystem called The Kalundborg Symbiosis. In the basic idea every residual product of an industry is used as resource for the next, all of this in a closed loop system. What is so particular in this type of system is that private and public companies sell a variety of different product, from the steam, ash, gas, heat, sludge, and others that can be physically transported from one company to another. The aim of all of them is not to waste. So what in a normal life cycle is considered not to be reused, in this case becomes something worthwhile, and not only for the money purpose. Thanks to this system, 3 million of m3 of water have been saved due recycling and reuse. Clearly the purpose that lead all of this is the economics benefits coming to the industries that work in this system. The possibility of selling waste is economically worthwhile, and if this can lead to a better environment the question is why not? From this we can understand that the material and energy scarcity that we face in some part of the planet can be avoided or totally reset if we think not in a linear way of producing.

Kalundborg Symbiosis has developed gradually over time. From the earliest cooperation between Kalundborg Municipality and Statoil (then Esso) for the supply of water to the extension of Statoil’s production in 1961, to a real symbiotic relationship that was established in 1972. Since then, companies have continuously implemented symbiotic practicies, and today there are more than 30 exchanges of water, energy and other by-products between Kalundborg Municipality and eight other companies: Novo Nordisk, Novozymes, DONG Energy, RGS90, Statoil, Gyproc, Kalundborg Supply and KaraNoveren. In addition, a number of agricultural companies have an interest in this type of industrial symbiosis, as purchasers of fertilizer products and waste heat.

This extends beyond the economic benefits involved with the transfer of waste products, surplus heat and water, and these very different companies see the potential of joint-problem solving and development for the area.

Another example of how circular systems are useful in the economy of a country can be expressed by the project of the civil engineer George Chan. He designed a sorghum brewery in Namibia in which nothing is wasted. Breweries usually use large quantities of water and grains, of which only a small portion remains in the finish product. Often the alkaline waste water, which contains low levels of biological contamination, undergoes expensive chemical treatment before disposal and the spent grains are given away as cattle feed. The latter outcome is far from being ideal because the grains are too fibrous and this results in the cattle producing more methane, which is known for being one of the worst greenhouse gases. The approach that gave the success to the project was the assumption that all the problems could have seen as opportunities for adding elements to the system that created more value from exactly the same inputs. One of the solutions that the engineer gave was the use of the waste water as a base for the cultivation of the alga Spirulina. This product is reach in protein and micronutrient and is very effective for fight the malnutrition, a problem very common in more and more country in Africa. After this the water was used for fish farming, creating this way another source of protein. The remaining part of the grains were used as substrate for cultivating mushrooms, considering that one tonne of mushroom can be produced by four tonnes of grain. After the mushroom cultivation, the substrate, rich in fungal mycelium is then more suitable for animal feed or earthworm composting. The earthworm were used to feed chickens and the manure that went to an anaerobic digester, which produced gas for the brewery and local people to reduce the demand of wood. At the end of this long process what was reached was the production of 12 different products instead of just one. Seven times as much food, fuel and fertilizer; four times as many jobs as a conventional approach and a fraction of the waste. We can say that this, in the evolution of the production systems, is only the next step. Infact, the zero emissions is simply the continuation of the drive of industry toward higher levels of productivity and away from waste. After zero defects (total quality), zero accidents (total safety), zero inventory (just-in-time), zero emissions means that all raw materials will be fully used.

Again, what we face is that reinterpreting the nature and the function of nutrients and energy emerge that is possible to have better solution and greater resource efficiency.

As seen in this examples changing the future of the Earth is possible, it’s not a mirage or something that we cannot achieve anymore. If we change our point of view, starting right now to apply the circular economy we can still have chances to save the planet for the future generations.
