I believe the rial response to climate change is to create buildings that can heal the environment when we currently think about this.
In architecture, we focus on reducing carbon dioxide emissions in other words, recycling materials, using more efficient technologies on linking our buildings up to alternative energy systems.
What we're trying to achieve is a carbon zero building, one which, when it's up and running that does not produce any net carbon dioxide emissions.
Here's an example.
The Green Light House, Copenhagen.
Now what this building on other buildings like it do not achieve is to address the relationship at the heart of building practice, namely.
But making a building has a negative impact on the environment On this is really important because carbon zero policies only slow this down on.
There are plenty of other things happening in the built environment that is speeding the whole process up.
For example, in the next 40 years, we'll see another two billion people on the planet.
70% of them will be living in cities on will have to build homes for them.
So unless we change this relationship from a negative to a positive one, they're now building industry is set to have a huge negative effect on the health of the planet.
But how might we do this?
Last year I gave a presentation about how it may be possible to create a building and grow it, using a new technology called a protest.
So this is a chemically programmable agent based on the chemistry of oil and water on At the time, it was just a concept.
But now we've started to engineer the technology, and I can show you a protest.
So building a solitude of crystalline material.
Now, I just want to make sure you know what you're looking at cause it's wonderful.
In the center of the picture is the protest.
So it works by energy at the oil water interface, and that's around the edge of the droplet.
In real life, this is all just about visible with the naked eye.
The protest cell has an internal chemical program on.
It compares this with what's happening in the chemistry in the environment.
On the output is to create this autumn tuba crystalline material.
Now all of this happens without any DNA.
No D N A.
This means this is not alive and yet this process is incredibly biological.
It's reminiscent of the way that Jude worms or corals might to treat their shells on because of the heart of the proto cell is a general chemical program.
We can change it.
We can engineer it to create different kinds of materials.
So here's another one that can produce a limestone like substance from dissolved carbon dioxide.
Now we have a technology that can make a solid material with biological like properties.
What could we do with that?
We've been making a paint for the surfaces of buildings, using this protest cell technology to create a new interface between our buildings on the environment for carbon capture and storage by literally growing a limestone coat around it.
Now, this doesn't require us to make great buildings.
This requires us to create a transformation off existing building stock.
And, of course, that sighted exactly where our pollutions and emissions are actually being produced.
On.
Although this technology is that it's early stage of development, it's already showing us ah, whole new set of tools and technologies that may be available for us to create buildings differently.
But more importantly, it gives us an opportunity to change this relationship at the heart of building practice.
And it's time to think beyond carbon zero policies and create carbon negative architectures, ones that, in the process is on the materials of their construction, actually remove carbon dioxide and perhaps other substances from the environment on all the results that we've had in the laboratory suggest this is possible.
Thank you wth e Electric Grid was conceived in the age of Edison, designed an age of Eisenhower installed in the age of Nixon, and it has not been upgraded since.
It's just not able to keep up with modern needs.
The notion of this Margaret is using what we have better making do with what we've got and not build so much.
New infrastructure software at the gateway between generation and transmission can solve that problem.
This Margaret is actually a bunch of smart devices connected over a network to a bunch of computers and computers, crunch all this data and then are able to optimize the system.
What we're working on is helping utilities see what's actually happening in real time in terms of the flow of electricity between all those devices, benefits the consumers benefits the environment, all because of things we can now see that we couldn't see before on the Olympic Peninsula.
Pinellas goal was to make the smart grid tangible way were taking home area networks as a way of sending messages to the homes and to the devices in the homes about when they should run or not run.
There was one other modem here that captured wirelessly the reports from the different elements we saved approximately during this time 15% of our electric bill.
If we could do that for everybody in the country, we're talking about saving $100 billion worth of infrastructure that we won't need to build.
IBM is the first big company to really see the opportunity to marry information technology with the grid.
There are similar things going on in South America, Asia In Europe.
We've been working with Malta to make both of water and electricity systems much more efficient.
It is a model for how we can then bring that to other, larger geographic areas.
The path forward to a smart grid is actually quite clear, we upgraded.
Our telecommunications networks are satellite networks on.
We can do the exact same thing with the smart grid.
A wind plant will go up and down by the minute a solar plant will go up and down.
His clouds go over.
So having agreed that conflicts itself and manage these these kinds of things is critical.
We need to be planning for the kind of future that we say we want, which is an air of cheap, reliable, clean electricity for decades to come.
