Whoever said that "it's not easy being green", must have known what he or she was talking about. Of course, science has made some remarkable progress over the last decade when it comes to clean energy, but how many of those developed clean energy models have actually been integrated within the architecture of our homes and offices? (Power sockets excluded.).
We can hear you think, that stationing a big eco-friendly power plant on your rooftop would perhaps be a little too much, but somewhere in the nearby future you could consider to let nature take over the office building you work in!
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

This is an old fix to a constant problem. We used to have these water cooling units on the top of our buildings. Electricity was necessary, when the wind didn't blow, and it was also necessary for the blower. I like the design of a hole in the center of the building to circulate air.

Add solar powered blowers 2 not need as much electricity. And you could even add batteries that the solar panels are charging to use when the sun is not strong.

I didn't meet anybody who would complain about air conditioning during hot summer. The ventilation systems have silencers in canals, the air flow velocity can be set up. Heat pumps are quite common. But what he didn't mention is the borderlines for project that determine building height, size, type, surroundings, local law regulations etc - it all has impact on the shape of the building.

Hi Ben... its my pleasure to see your presentation its my dream as well, Its really great work, I'm having an interest of getting every thing at home from natural resources zero in zero out self-sufficient houses moreover a productive houses, organic foods, healthy ,I'm a one person who believe on this dream I know it is huge and I should decompose it into small projects, but I don't know how to get people convinced with the whole project , to give a budget to realize these things is a proposal sufficient? Is it the media? etc...Thanks in advance..

Dig a tunnel below ground where the temps are cooler. In this underground tunnel place a coil of pipe to run water through and into a heat exchanger system. it's called geothermal.

I think for implementation for actual condition is not simple, I understanding the concept, the cooling effect is due to the latent heat that needed to change the liquid phase to steam phase of water. and the heat is taken from the air that passed trough the water. after the air trough the spray water the air become colder then inject to the room, with the same time the air became humid (the humidity) increase and this condition will limit to change the process of phase changes (from water to steam) and make the cooling effect will also stop. For big capacity of cooling load i think this concept can not be implemented for instance cooling load 250 Ton refrigeration up, cause the cooling effect that produced by this concept will not enough.Cooling effect is produced by latent heat of water.

Simple question that he doesn't answer: What happens to all of that "moist water vapour" that comes from the water cascade? It cools the air in the summer and preheats it in the winter, (that's understood). However, where does all of that water vapour go to? Are you using it the "humidify" the building? It could get very uncomfortable to have a relative humidity about 75 percent. No fans to help circulate that air? Water vapour is lighter than air, so it would easily accumulate in the upper floors, (very muggy, even if the temperature is low). Unless you have an arid (dry) climate, you should also be looking at "dehumidification"; but, it's not mentioned in this presentation. Those termite mounds are usually found in arid climates, (not in the Netherlands).

It seems their orientation (long wide sides E-W, narrow sides N-S) helps create difference in temperatures. Basically until midday sun will heat up one side, whilst the other will remain in shade and relatively cooler. This will cause air convection inside the mound due to difference of air density between sides and interior vs exterior. Sun is in fact powering their air conditioning and in more shaded/forested environment it's more difficult to control inside temperature.

No person who lives in Phoenix Arizona does not complain about air conditioning. We need artificial air conditioning here during the summer. Why? Well even at night it doesn't cool down. It holds the heat. There is no cool air breeze here. For inventers like this guy. You should live a year or two in Arizona and think about natural air conditioning here. But nothing about AC bugs me other than the energy bill here in Phoenix.

@Halopa60
@Halopa60 4 года назад
Yes but incorporating those design principles resulted in a 40-60% reduction in energy consumption and don't forget the power generation produced by the building via wind and solar PV accounts for all or nearly all the remaining energy needs of the building. Obviously is a great step in the right direction. What we need now is for close minded and stubborn architects to start promoting this to their clients.
