The points i have have chosen are space , solar pannels and technology
Space for buildings: Large metropolitan areas do not have enough residential buildings. Especially at the medium and low income range and that's include a large proportion of young people at the start of their career. Young people today will find it much more difficult to buy a house or flat than their parents did. This is true both in the developed world and in the developing world. We see a big social push to build available houses. Sometime in unusual places, such as reclaimed sea land.
Solar panels : Solar use in buildings will continue to grow, primarily because a number of U.S. states are expected to implement aggressive renewable portfolio standards (RPS), even as the whole country moves toward zero-net-energy buildings.
In mid-2015, 37 states, among them California, New York, and Texas, had some form of renewable portfolio standard, mandating a percent of total electric generation from renewables. California’s RPS is the most aggressive. It mandates one-third of total electric generation to come from renewables by 2020.
The persistence of low interest rates in the U.S. makes financing capital-intensive solar energy systems easier, especially in combination with requirements in many states that electric utilities implement “net metering” programs. Such programs pay building owners for surplus electricity produced at the same rate as power purchased from the local utility. In the U.S., most electric utilities would rather build and control large central solar power plants than lose revenues to tens of thousands or possibly even hundreds of thousands of rooftop PV systems feeding solar power into “their” grid.
New tools will further encourage building owners to use solar power. Google’s new Project Sunroof, announced in August, combines aerial 3D models from Google Maps, historical weather data, utility prices, and the value of local incentives. From this information, anyone will be able to readily assess whether covering a rooftop with PVs would result in energy cost savings.
Solar power has one advantage over other forms of energy efficiency. It is highly visible. Photovoltaics on the roof of a building demonstrate to employees, customers, and the public that a firm or institution is committed to renewable energy and a greener future.
Solar electricity is likely to reach grid parity in the U.S. within the next five or six years, by 2020 or 2021. In June, Bloomberg New Energy Finance predicted that solar power costs would fall another 50% and solar investment would total $3.7 trillion in the next 25 years, of which 60% would go to rooftop and decentralized systems.
Of the 10 megatrends discussed here, solar power growth is the only one that is truly revolutionary and likely to radically alter how buildings are designed, built, and operated in the next 10 years.
Technology: Architects around the globe have actually been racing to build the world's first 3D-printed house.
In China, a company named Winsun said it built 10 3D-printed houses in one day — each costing just $5,000. A professor at USC is working on a gigantic 3D printer that can build an entire house, with electrical and plumbing conduits.
Pearson said the ability to 3D print cheaper houses will be a major asset as cities become increasingly more crowded.
People could control all of their homes with virtual intelligence:
We're actually already starting to see this with products like Amazon's Echo, which lets users control the lights in their homes and access other information. By 2040, AI will be built into buildings themselves, so you can talk to the building and ask for adjustments in temperature or lighting.
"Artificial intelligence will be a big home servant," Pearson said.
Super tall buildings could function like mini-cities in the next 25 years:Pearson also highlighted this in a report he put together with construction equipment rental company Hewden.
More cities will elect to create high-rise buildings with floors dedicated to gyms, residential space, and office work to accommodate the influx of people that will move into cities over the next two decades, Pearson said.
Best case: we continue to advance in our technology and have smart homes that are 3D printed and do not cause a lot of pollution and run on green energy and solar pannels. These houses will be cheap to make and good for the environment so there will be houses for everyone.
Worst case: the air is polluted and there isn't enough space for buildings, all of the resources to build the houses aren't available and they will be expensive.
Motst probable: that the world won't be as polluted as we expected because there is a lot of environmental campaigns and technology will advance.
