Analysts predict that in thirty years, 80% of the world's population will live in cities. Fantastically beautiful and, importantly, environmentally friendly "Rainbow Tree" is a great idea to live in the city and at the same time be constantly in nature. After all, this skyscraper is essentially a vertical rainforest. And it is made of wood … Moreover, this project is not at all a fantasy: the building will be built in the near future.
An innovative building in the "creative city"
"Eco-friendly skyscraper" designed by the Paris-based company Vincent Callebaut Architectures, will build a building in the business park of Cebu City. This town is located in the heart of East Asia, in the Philippines. Young designers, architects, artists, researchers live here. Cebu is the oldest city in the archipelago. In addition, it is the largest seaport and a major economic business center, specializing in emerging information and communications technology sectors. On 31 October last year, UNESCO designated 66 new "creative cities". Among them - and Cebu, which received this status for its innovations in the field of fashion, architecture, design and production of sustainable furniture.
"Skyscraper of the Future" will be built inside the Cebu Business Park with an area of 50 hectares. Within the new circular economy, the Rainbow Tree is the prototype of a fully bio-based vertical forest that respects the four pillars of the ecological city of the future, namely: energy self-sufficiency (heating, cooling and electricity); greening of buildings and development of urban agriculture; soft mobility (emphasis on pedestrians) and social innovation (spaces for residents and services to share).
Eucalyptus building
Experts note that humanity now needs to consume a minimum of resources while reducing waste and greenhouse gas emissions.
“At a time when we need to find radical solutions to reduce the global carbon footprint, we designed a 32-story, 115-meter tower built from solid wood, because it is the only natural, abundant and renewable material,” the architects say. “This organic tower integrates the principles of passive bioclimatism and advanced renewable energy sources. We named the building "Rainbow Tree" after the Deglupta eucalyptus, also known as the Rainbow Eucalyptus, an iconic and colorful tree from the Philippines.
Rainbow eucalyptus has a tendency to constantly shed its bark, which comes off in long and thin stripes, exposing a trunk that changes color over time. Degluptere means peel in Latin. The trunk of this tree is at first pale green, then it turns blue, purple, orange and finally brown. Thus, its trunk is a mosaic of flowers, giving the tree the appearance of a real rainbow! One would think that someone specially painted the eucalyptus with paints, but all its colors are 100% natural!
The Rainbow Tree Tower is decorated with some of the most beautiful living plants from the local rainforest. Its surface is covered with a real forest of more than 30,000 plants, shrubs and tropical trees. From a distance, the house looks like a blooming spiral in the colors of a rainbow, and this building will bring a breath of freshness to the architecture of the Cebu Business Park, which is mainly built of concrete and steel.
A skyscraper that cleans the air
The high-rise building is a checkerboard geometric stack of 1200 modules, each of which has sides measuring a meter long and a height of 3, 2 to 4, 8 meters. All of these bulk modules are designed with a very high degree of precision.
This building literally breathes. It is in symbiosis with nature, construction is based on excellent ventilation, large open interior spaces and terraced networks, adapted to the tropical climate. Invented in the 1990s in Austria and Germany, this construction method consists of stacking timber planks perpendicularly and bonding them together using structural (now organic) adhesives such as tannins, lignin, cellulose, or even starch.
- The process of producing cross-laminated wood requires much less energy than concrete or steel, and, moreover, it does not generate greenhouse gases, - explain the creators of the project. - Recall that the production of 1 ton of concrete produces 2.42 tons of CO2, and the production of 1 ton of steel - 0.938 tons of CO2.
By the way, it is known that 1 ton of wood produced accounts for about 0.9 tonnes of carbon, which means that in the case of the Rainbow Tree we are talking about a building with a negative carbon footprint.
The project's authors promise that the 30,000 plants, shrubs and trees planted on the tower will annually capture 150 tons of CO2 in the atmosphere of Cebu City to convert them into oxygen through natural photosynthesis.
At the same time, architects debunk the opinion that wooden houses are easily susceptible to fires:
- If we talk about fire resistance, then wood burns slowly, does not emit toxic fumes and transfers heat 250 times slower than melting steel, and 10 times slower than concrete, which cracks under the influence of flame.
How an eco-friendly home works
The rainbow tree is covered with sinusoidal wooden balconies that resemble tree branches and are staggered between odd and even floors, allowing palms and deciduous trees to grow at double heights. Endemic plant species will be planted according to their bloom color (pink, purple, green, yellow, orange, red) - to draw five plant spirals wrapped around solid wood facades.
This forest house allows you to fight the effects of the city heat and is a real island of freshness.
Inside the building is planned as follows. There are parks in the basement (levels -1 to -3). On the ground floor there is a catering restaurant, a bank office and a bicycle parking. The second floor houses offices, coworking spaces, etc. From the 3rd to the 6th floor - parking spaces for cars and electric vehicles. The seventh floor is dedicated to the pool and spa. On the eighth - a fitness center. And finally, from the 9th to the 30th floors are apartments.
On the 31st floor of the skyscraper, there will be an urban "sky" farm, where it is planned to produce fruits, vegetables and algae using the aquaponics method. These products are grown without chemical fertilizers, pesticides or GMOs - on natural fertilizers. The inhabitants of the Rainbow Tree themselves will harvest the crops.
The Sky Farm is capable of producing up to 25,000 kilograms of fruits, vegetables and seaweed, as well as 2,500 kilograms of fish per year, or almost 2 kilograms of food per week for each family living in the tower.
Well, on the roof, as befits an environmentally friendly building, photovoltaic and thermal solar panels will be installed. This “solar shed” covering the farm is capable of generating electricity and heating water, which is then redistributed in the bathrooms and kitchens of the apartments.
In addition, 16 axial magnetic levitation wind turbines will also generate electricity, and without any noise.

Why is there only one station in the Omsk metro and what happens inside
Anyone who first came to Omsk and does not know anything about this city, having seen the entrance to the metro with the corresponding logo, the letter "M", will certainly want to ride in the subway. However, despite the endless stream of people (some come in, others come out), there is no subway here. The fact is that only one metro station was built in Omsk, while the rest did not have time to open. To date, there are no plans to complete the subway. Therefore, the townspeople use the metro station "Library named after Pushkin"
What is the only Stalinist skyscraper in St. Petersburg famous for, and what does Viktor Tsoi have to do with it?
"House with a spire" - this is the name of this high-rise building in St. Petersburg, located at the end of Moskovsky Prospekt. And since Soviet times, it has received the nickname "General's House". Why is not difficult to guess. I must say that many interesting facts are known about this famous and mysterious St. Petersburg building - the only Stalinist skyscraper in the city, but the architecture of the unique house is no less remarkable
Why does Russia need church reform and what does Ukraine have to do with it?
In the 17th century, important foreign policy and objective internal reasons prompted Tsar Alexei Mikhailovich to reform the Church. The sovereign wanted to take advantage of the situation when Russia had the opportunity to become a stronghold of world Orthodoxy. Because of the old centuries-old rituals, Russian church traditions were at odds with the canonical Greek ones, which needed to be urgently corrected. But the radicalism of the reformers and the crude methods of innovation gave rise to a schism unprecedented until then, the echo of which cannot be

On the account of Vladimir Epifantsev, there are more than 100 acting works in films and TV shows, in addition, he himself makes films and puts on performances, takes part in scoring and shocks the audience with provocative, and sometimes rather harsh, videos on the Internet. But the public outrage was not even caused by them, but by the recent statement of Vladimir Epifantsev that he does not communicate with his children, born in a marriage with actress Anastasia Vedenskaya, and does not plan to become a father anymore
Buddhist Forest: What Really Happens in a Japanese Sculpture Park That Fears Tourists
Photos of this quaint park filled with many stone sculptures appear periodically on the Internet and are invariably accompanied by comments that this is a very scary place. The Japanese park (or rather, the forest, of which there are even two) is somewhat reminiscent of either a cemetery or the Chinese terracotta army. Nearby residents add fuel to the fire, assenting to tourists: they say, yes, all this is very creepy. In fact, the history of this place is not at all scary, but naive and romantic
