tomorrow today. in 60 minutes on d w. i don't need to keep up to date on the people over for over lunch and home the force i'm. most missing in the lives of others the bottom of the valley is at the last dragon as well as a cold the heart to use. on. the smithsonian he risks solution or especially with regard to. the construction sector is responsible for 60 percent of waste.

and should concentrate on watching acetate treat cell 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 the only work there or will we continue to live there too. could empty stores be 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 if you 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 we're 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 new functionality is the death knell for urban development he destroys the city leave the u.p.a. . versus an. industry. there need to be people living and working. all. the pandemic has highlighted the urgent need for end of a shift in the us coast shopping malls have been a problem for some time. here in cupertino california this once dead mall is currently being completely redesigned it will still have stores and offices but also housing. sports and administrative facilities a sustainable new urban district serving a variety of purposes topped off with the rooftop park. and to my. from the city council share the same vision for. a neighborhood in the

center of frankfurt it still takes some imagination to envision the new district the plan foresees an area that incorporates greenery 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 retail sports facilities and commercial estates the aim is to diversify rather than to maximize yields. there is usually. an spaces. streets and must have different characteristics. the importance of avenues parks and courtyards for city dwellers is not a new insight in this respect the future will be reminiscent of the late 19th

century urban planning. to recreate the past just searching through the seas. and into man and here this is what. 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 space is already in short supply so that green spaces are preserved. architect. advocates for converting existing buildings by adding more floors. story carparks can be converted into commercial and retail space and apartments like here in. social facilities. can be built on rooftops for example

a daycare center has found a new home at the top of a car park. a more sustainable and often cheaper solution than building from scratch. office buildings can be repurposed and supermarket roofs can be topped up to come on estimates the potential of 2000000 apartments nationwide he's optimistic that space can be put to more efficient use in german cities. german cities are not that densely populated vienna are serious of the highest quality of life. which is twice as densely populated as frankfurt long so its population density is twice as high as frankfurt's and the challenge is to find a good solution 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. 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 . and 100 hile from architects for future say it's time to construction industry between 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 of their clergy a great new building is done but if what are to exist. is used this tends to be

better in terms of c o 2 any given building contains what's called great energy the sum of all the energy required to produce a product if a building is torn down and none of its materials reused 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 marks pensive 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 brooklyn and use it as their office using only recyclable materials tricks are good examples 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. cradle to cradle switch systems it's all biodegradable and recyclable and healthy and issues that something can be built

easily dismantled 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 as. we use to recycle and repair what we had because there was no other choice to 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 all 3 of structures. the use of wood and cancer. action

can save on emissions prints you can park in munich it's a model timber settlement with $570.00 apartments there's no waste when wood is used even the shavings can be used to spew and there are many other advantages. you know have to include some time to construct a building but stuart see the 2. to 3 percent more rental space can be created and there is more efficiency as well as other units in 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. through 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 trees have a positive footprint they foster life in their environment and i think that's a very important aim for people on this planet. sagna as are 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 of themselves in which case she didn't use them she kept a record of everything and put all the information about the materials into one folder . with. something. is worth. a society defining how this is the ideal one to build a house where there would be cycles and the materials that held their identity and could later. recovered to the heights as

a dozen buys what was known what they were and how they could be recycled. this is all documented in this folder. after committee. this could and should be the architecture of the future one that uses wood instead of concrete and favors renovation over building from scratch. but what if you do need to build standards regarding insulation ventilation and electronic regulation can be baffling ever new materials are used more and more technology more and more repairs for years architect florian not 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 some flooring nagware began his build simple experiment to decide holmes using this little technology is possible and fewer. materials to return to what he sees as a truer building culture. the robots released we considered whether this build simple concept work with conventional construction materials was the most common materials used in home construction here 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. rooms firm funded the project he's fascinated by the built simple. the concept here is simple

doesn't mean small are ugly quite the opposite the rooms are inviting areas and over 3 metres in height. that see idea height helps height contributes to qualities like thin air quality i not much team calculated how a space can be he didn't want turn and cooled in summer walk in sumi his little energy as possible to do that they conducted $2600.00 computer simulations using rooms of all shapes and sizes. of britain france and europe i mean who are those with high ceilings work best like are ones common in older buildings some of the 3.3 beaters not from which reasonably large windows not too big not too small it was good enough to ensure the room's well lit and it's all over but start with the wind of. this are really good example. of this window lies inside was different this is not a surfeit of 40 centimeters which means you don't need any blind person or any

additional something critical because the sun doesn't shine directly into the wind of austin to go since i was really blanco zings are firstly i made a fuss and secondly brooklyn after 15 years of use next we have this horizontally pervasive wind which also provides better than delicious fresh air comes in at the top because at the buffet. 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 hero to the house call 1st off everything you will need all those can't break donors and as a. that doesn't have movable parts isn't as likely to break down as things the

tooth 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 as an age old building that and some old shapes are also enjoying a revival current sense romans used to tempt home create which had no steel reinforcements so they couldn't make pretend to their window frames instead they developed around arches like those in roman to telekinesis. there's in places to toggle so there's a lot of interest because most people are sick to death of his over use of technology and of the restrictions and who is by this technology of which inhibits

your freedom when designing and making architecture of it so people are very open to this idea and are following it closely as for fordham's if you limit closer and closer this pilot project and bad typing 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 arch with an untreated will or. it was designed by anna heading up a pioneer of sustainable construction. in flight. i have like i want to change the world with architecture. creates

a pleasant indoor climate in germany it's 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. is also water soluble and that's a very important and wonderful quality because it can easily be recycled clay 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. 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.

your sustainable building concept is in demand worldwide and she teaches at harvard immunise answered and is one of the few women to run her own architectural firm. again and again she feels drawn back to bangladesh. values participation and equal rights to. the village both men and women have joined in to build this award winning 2 story therapy center for people with disabilities. for many years focusing on construction projects of her. sister ship coming in. including a claim for the worms cathedral. his 1st building me to play in europe went up in 2016 a birthing room and a street. once the projects in who's in time periods completed

move on to the next construction site this time and. how many color nuances clay had from reddish yellow to dark brown. but 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 need to go. find it off you know 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 of comes a little closer to achieving that goal she may not change the world from one day to the next but every step chance.

here there will be a cable car flying overhead and of course they're afraid will it go over my garden or bother me hauling 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 this country we all live according to the principle of just to do anything. and that's dangerous we need to take more risks bolder solutions especially with regard to us that's it is with us that's it if you notice very quickly whether something is still small and. could. specious inviting and inspiring.
