they want to know what makes the devil you just. love being here and banning thing never way up. i'm not even allowed to wash my own car and everyone was laid a holes in everything. getting you ready to meet the germans then join me right just do it under. the sun was merely to take the risks solution or especially with regard to assess and steve to show he. thinks the construction sector is responsible for 60 percent of waste. so it means we should concentrate on what take troops construction itself provide the solution.

it's time to explore new perspectives in architecture what with the pandemic now more than ever with many of us working from home and shopping online city centers are increasingly empty and the construction industry is disastrous for the environment responsible for over a 3rd of global carbon emissions. once the coronavirus crisis is over will our cities become more green than gray. will be only work there or will we continue to live there too. could empty stores. the revived with completely new functions. architect christophe

meckler believes that the crisis is an opportunity to bring greater diversity to germany's city centers. on. the coronavirus crisis is actually a catalyst to see shopping precinct. change is going to come is there's a reason why they're in this sorry state. is in shopping precincts like this one in frankfurt were already in financial difficulty before the crisis struck but since the pandemic shoppers tourists and commuters have stayed away whilst online retail and home offices are booming retail spaces are now shuttered the demand for office space is also decreasing everything is closed shopping and business districts are dying as a deal more no from the new functionality is the death knell for urban development

it destroys the city. versus an. industry. there need to be people living and working. for. the pandemic has highlighted the urgent need for end of a shift in the us ghost shopping malls have been a problem for some time. here in cupertino calif this once dead mall is currently being completely redesigned it will still have stores and offices but also housing culture sports and administrative facilities a sustainable new urban district serving a variety of purposes topped off with the rooftop park. and might you'll see from the city council share the same vision for. a neighborhood in the center of frankfurt it still takes some imagination to envision . new district plans. and serves

a range of purposes. for now it's a commercial and administrative area but the idea is to build $20000.00 apartments close to schools sports facilities and commercial estates the aim is to diversify rather than to maximize. the. spaces. streets and. different characteristics. of the importance of parks and. is not a new insight in this respect the future will be reminiscent of. urban planning. to recreate the past.

here. people who live in small city apartments need green spaces and parks especially during the current crisis in places where there is a shortage the demand for houses with gardens in the suburbs is increasing but how can this work in the inner city how can there be more affordable housing in areas where spaces are. so that green spaces are preserved. architect. advocates for converting existing buildings by adding more floors. carparks can be converted into commercial and retail space and apartments. social facilities can be built on rooftops. for example a daycare center has found a new home at the top of a car park. and often cheaper solution than building from scratch.

office buildings can be repurposed and supermarket roofs can be topped up take him on estimates the potential of 2000000 apartments nationwide he's optimistic that space can be put to more efficient use in german cities. dish german cities are not that densely populated vienna are serious of the highest quality of life. which is twice as densely populated as frankfurt wrong so its population density is twice as high as frankfurt's and the challenge is to find good solutions so the pandemic has shown how quickly things can change but change is also opportunity and architects and urban planners need to see is it. 6 the construction sector accounts for over a 3rd of global c o 2 emissions cement alone is responsible for 8 percent it's time for a change. to

the placenta instruction sector is responsible for 40 percent of emissions in germany and it's even responsible for 60 percent of our waste so it's a powerful force him to stick this been achieving climate neutrality is not enough we actually have to remove c o 2 from the atmosphere it's already too warm climate change is happening too fast entirely and then train hile from architects for future say it's time to construction industry became climate positive to do this there has to be more innovation and less building from scratch. to how to use what already exists so much more. great new building is done but if what are the existence is used this tends to be better in terms of c o 2 any given building contains what's called grey energy the sum of all the energy required to produce a. product if

a building is torn down and none of its materials are used this all goes to waste yet buildings get demolished all the time for instance the arabella building in munich which only just turned 15 and the central train station some argue that it's mark spence have to renovate a building meant to build one from scratch but they're not taking great energy into account it's not everyone to cradle to cradle and decided to renovate a high rise building in berlin and use it as their office using only materials electric circuit example as you can see usually you don't see these people it's because they're built into the structure and it's difficult to get that. system into the types cradle to cradle switch systems it's all biodegradable and recyclable and healthy and issues that something can be built easily dismantle from time. to cradle design create sustainable products for the circular economy the

idea is to reuse materials and not produce any waste so as to drastically reduce the construction sector's emissions it's actually not a new principle. what is relatively new is the disposable culture that has also taken hold in the construction sector over the past few decades. we used to recycle and repair what we had because there was no other choice even have tempered houses would be converted 2 or 3 times there are plenty of examples in germany. but then during the economic boom era there was enough wealth and we could afford to become a disposable society so we couldn't afford it before. beams that had already been used can often be found in alternative structures. the use of wood and construction can save on emissions prince eugen park in munich is a model timber settlement with 570 apartments there's no waste on wood these used to. even the shavings can be used as fuel and there are many other advantages.

you know how one could say it takes less time to construct a building but stewards c o 2. up to 3 percent more rental space will be created and there is more efficiency as with other units at the same density we should build apartments all. the time you asked her and her husband built this house in perfect 6 years ago according to cradle to cradle criteria there are only recyclable materials and the large what was untreated the house was inspired by trees. was. all. its own and it absorbs solar energy and store c o 2 anything that a tree doesn't need decomposes into the soil. so this material circularity is there was a t.v. for trees have

a positive footprint they foster life in their environment and i think that's a very important aim for us people on this planet. sagna as her wanted her house to be a sustainable as a tree she asked all her suppliers for detailed information about the materials which some of them did not know themselves in which case she didn't use them she kept a record of everything and put all the information about materials into one folder . is worth. a society defined and how was the idea was to build a house where there would be cycles and the materials that held their identity could later be recovered to take the hides as a dozen buys to see what was known what they were and how they could be recycled to have a cycling conference this is. well documented in this folder this after committee.

this could and should be the architecture of the future one that uses would instead of concrete and favors renovation over building from scratch. but what if you do need to build the standards regarding insulation and electronic regulation can be baffling ever new materials are used more technology more and more repairs for years architect florian played along with this over use of technology in architecture. some point i just felt set up i didn't want to keep on trying to develop a new technological element or search for a new technological solution i thought maybe we should concentrate on watching the architecture itself the construction itself provide the solution but i did. not there began his build simple experiment to decide homes using as little technology

as possible and fewer. materials if mark to return to what he sees as a truer building culture. though it's released we considered whether this build simple concept work with conventional construction materials is the most common materials used or who construction or reinforced concrete and brick or just trying to see if you could simplify anything about these 3 construction methods and simplify them they did the 3 pilot research homes and are now ready for occupancy the structures are plain yet attractive the philosophy behind them is clear for all to see less is more. than streams firm funded the project he's fascinated by the built simple concept here simple doesn't mean small are ugly quite the opposite the rooms are inviting airy and over 3 metres in height. they. that's the idea that height helps height

contributes to qualities like the air quality. knockers team calculated how a space can be heated in winter and cooled in summer while consuming as little energy as possible to do that they conducted 2600 computer simulations using routes of all shapes and sizes. of britain france and europe i knew the words with high ceilings work best for ones common in older buildings so i made the key point 3 meters from which reasonably large windows not too big not too small it was good enough to ensure the rooms well lit it's all more or less start with the windows. this are really good example. of this window lies inside and then there's your associate of 40 centimeters which means you don't need any plane has an edge or any additional something critical because the sun doesn't shine directly into the wind of austins since all those things are firstly made of plastic and secondly brooklyn

after 15 years of use next we have this horizontally pervasive wind which also provides better ventilation fresh air comes in at the top because at the bottom. homes walls are made entirely from one material only whether it's concrete wood tar brick they don't need any additional plastic insulation for example inside the technical and electrical systems are made to be as simple as possible. pipes and wiring are easily accessible so if something breaks down it can be fixed fast that's important to answer is construction firm conducts repairs on behalf of house and companies. i mean we make a 1000000 repairs each year so we can break down or we wrote in a house call 1st off everything you amid all this can't break donors and everything that doesn't have movable parts isn't as likely to reach as things the key to life with the new t.p. reflex and should these homes be torn down at some point. they'll also have an

advantage other buildings don't greener waste disposal. moves if it's just brick you can recycle the brick if it's just wood you can recycle the wood or burn it for fuel it's less it's just concrete you can recycle the concrete but the moment you combine those things mix them it usually lands in the hazardous waste and. construction of an age old building that and all shapes are also enjoying a revival current sense the ancient romans used tamped concrete which had no steel reinforcements so they couldn't make rectangular window frames instead they developed round arches like those in roman the celica as he does in places to toggles there's a loss of interest because most people are sick to death of his over use of technology and of the restrictions imposed by this technology which inhibits your freedom when designing and making architecture. so people are very open to this

idea and are following it closely as for ford and see if you limit grossman to assume this pilot project in bad driving could alter the future of construction and herald a return to architecture and its purest form one that uses just a few natural materials to create sustainable housing or simply put it's simple. this iron fit a center in rosenheim a city in the southern german state of the varia looks like a huge bird's nest. it's made of jubal and untreated will or. it was designed by an a herring and a pioneer of sustainable construction. if i'm not i have to go i want to change the world with architecture clean creates a pleasant indoor climate in germany is more expensive than conventional building materials. and it still doesn't have

a great reputation in fact has many advantages. absorbs harmful substances and it's environmentally friendly. it's also water soluble and that's a very important and wonderful quality because it can easily be recycled clay it can also be repaired very easily it can edge breaks off you just what it is the same material to fix it by pressing it on top of the crack it will look just the same and nobody will ever notice the difference in this country clay can be recycled without any reduction in quality which makes it an important material and it's available everywhere it's literally beneath our feet we just need to learn to appreciate the material and be creative with how we use it. as another to make me work with manual without the use of expensive she. discovered her passion for cleaning and the use of looking resources at the age of

from reddish yellow wish to dark brown. you don't need any chemicals for it our problem is that the chemical alternative is always cheaper and that definitely has to change. this pioneer sustainable building user still weeks ago. i have often done my hope that architecture can really be a tool for improving living conditions and bolstering social justice and cultural diversity. and can help preserve this planet for generations to come. and with every new design and a heading it comes a little closer to achieving that goal she may not change the world from one day to the next but every step counts. who hasn't dropped out of seeing the world from above. can't.

or bother me when some bathing you must be quite cautious because tolerance levels are much higher in south american cities and they are in germany sure we have traffic jams and traffic issues and they're getting worse but internationally speaking they're not yet as a level comparable to sao paolo for instance and are europeans perhaps too complacent to strive for real change. in the moment since in this country we all live according to the principle of is just to do nothing wrong. and that's dangerous we need to take more risks time bolder solutions especially with regard to us that it is with aesthetics if you notice very quickly whether something is still small and dying or whether is open is specious inviting and inspiring. singapore.
