Aguçadoura Wave Park


For the last post of this year, I want to inform you of the first ever wave farm. Enjoy it and Happy New Year!

Aguçadoura Wave Park is the world's first commercial wave farm. It is located three miles offshore near Póvoa de Varzim north of Porto in Portugal. The farm uses three Pelamis wave energy converters to convert the motion of the ocean surface waves into electricity. The farm was officially opened on the 23 September 2008 by the Portuguese minister of the economy.

Developed by the Scottish company Pelamis Wave Power (formally Ocean Power Delivery), the Pelamis machine is made up of connected sections which flex and bend relative to one another as waves run along the structure. This motion is resisted by hydraulic rams which pump high pressure oil through hydraulic motors which in turn drive electrical generators. The three machines which make up the Aguçadoura farm are each rated at 750kW, giving an installed capacity of 2.25MW, enough to meet the average electricity demand of more than 1,500 Portuguese homes.

A second phase of the project is now planned to increase the installed capacity from 2.25MW to 21MW using a further 25 Pelamis machines.

New Green Complex in Singapore


A new green complex from world renowned architecture firm Foster + Partners will be adding more than a dash of green to the Singapore skyline. As sustainability becomes an essential ingredient to development in this island nation, the UK-based firm is leaving no stone unturned to make good use of alternative energy sources in this 150,000 square meter mixed-use project. As the winning design from an international competition, Singapore’s new eco-complex from Foster + Partners is pushing the green envelope from top to bottom in this sophisticated downtown design.

The complex will fill an entire city block between Singapore’s Marina Center and the Civic District with commercial, residential, retail, hotels, and a ‘green’ link to an Mass Rapid Transit (MRT) station. All facades will be fitted with solar cells and, to help control solar gain, direct sunlight will be filtered through ribbon-like canopies rising from the base of the entire complex to the exposed east and west elevations of the towers.

The canopies will form vertical louvers at the elevations and provide more renewable on-site energy with integrated thin-film solar arrays. Vertical green spaces, and extensive sky gardens are also important components of the towers, further greening the whole structure with natural vegetation and ambient temperature moderation.

The slanted facades are designed to catch the wind and direct it downwards for natural cooling of the ground floor spaces. A rainwater harvesting system, geothermal heating system, chilled beams and ceilings, and an ice storage system for cooling are further enhancements planned for the complex.

Renewable Energy Sources versus Fossil Fuels

In modern western world the demand for energy has increased dramatically in the past century and it will grow even further and harder in the near future than ever before. The need for energy rises with upcoming markets that also need more energy. Energy is needed for cars, buses, and other means of transportation, but also to run our appliances and provides us light. Energy is also important for our safety. At night or in the dark a lot can be stolen without proper lightning. Energy is therefore needed for our development and safety.
The way we use energy today comes from knowledge that has it's foundations in the past century and before. Great men like Newton and Philips have set the path for us today to make proper use of energy. The sources which we use for our energy demand are known as non-renewable energy resources. These sources will be discussed here in the article.

Definition of Non-Renewable Energy Resources

The name really explains it very well. Non-renewable energy resources are natural resources that cannot be recycled or re-grown. These natural resources are fossil fuels like coal, petroleum, and natural gas. It also includes mined resources such as the elements used in the production of electricity (uranium and plutonium, for instance). These resources replenish itself in a quicker rate.
Fossil fuels are very versatile. One of their functions is to generate electricity. In order to generate electricity, fossil fuels are burned through the process of combustion. The energy produced from the combustion process is used to power a turbine. The turbine is responsible for the conversion of energy produced from combusted fossil fuels into electricity.

Coal

Coal is one the most used fossil fuels. It is consider too be the most important energy source to produce electricity. The U.S. produces 50% of its energy supply through the combustion of coal. The coal itself is a brownish-black sedimentary rock which contains carbon and other assorted elements. It is extracted from the ground through underground mining or open-pit mining.

Natural Gas

Natural gas is also used to produce electricity. The electricity is produced through steam turbines and gas turbines. Because the gas contains methane the combustion emits less harmful gasses that have a negative effect on global warming. Thus natural gasses are better for the environment compared to petroleum and coal.
There is also another use for it and that is as fuel for cars. It is much cheaper that gasoline and produces less harmful gasses. The disadvantage of running your car on natural gas is that you need more fuel compared to gasoline and the car needs more maintenance. In countries like Argentina, Brazil, Pakistan, Italy, The Netherlands and India it is used as a fuel for cars.

Crude oil

This fuel is the most talk about for the past year(s). The prices for crude oil have gone through the roof and will be rising even more. The demand is increasing while there is less crude oil available. The term black gold is now more applicable than ever before.
The oil itself is very think in consistency and has a dark brown or greenish colour characteristic. It is a complex mixture of different hydrocarbons.
Crude oil or petroleum has various uses. It can be used as fuel or cars and different industrial machines. It is also used as a raw material for products like plastics, solvents, fertilizers and pesticides.
Although the need for crude oil is high and the demand is rising the available crude oil is decreasing. That leaves us no other option than to look for alternatives.
Non-renewable energy plays a very important role in our daily lives. Non-renewable energy will be needed today and in the future. Because this energy source cannot be recycled or re-grown the reserves are limited. The consequences of the shortages of fossil fuels are experienced today and tomorrow. We will need to use these fossil fuels wisely and will need to shift our focus to other renewable energy source. These are the sources that we need to focus on today and years to come.

Water Hybrid Conversion


As long as we are talking about alternative fuels (see E85), you might want to check out How to Run your Car on Water! Sounds crazy? Maybe. Is it true? Ofcourse! You just use regular tap water and you can save up to 40% in fuel costs. In addition you increase your mileage and engine performance and it produces cleaner emissions which means a cleaner environment! Check it out. Click Here!

E85 Fuel


The above supercar is a concept Ferrari F430. Beautiful and powerful car no doubt, but what is special about it is its capability to burn E85 biofuel. E85 is the term for motor fuel blends of 85% ethanol and just 15% gasoline. Besides its superior performance characteristics, ethanol burns cleaner than gasoline (e.g. up to 40% less gas emissions on the above car). It is also cheaper and above all, your car can become compatible (although a complicated process for the time being) to use it. More info on E85 fuel can be found here. As well, more info on the Ferrari can be found here.

Renewable Energy Solutions

In one of my older posts I talked about how you can build your own wind generator. There are methods where you can build your own wind and solar generators as renewable energy that can reduce the amount of household electricity by 80 %. In fact, by applying this knowledge, the electricity companies will actually pay you if you produce more energy than you actually use. I really like the whole idea. Once again it is actual proof that society is attempting to find ways to renew energy and save the environment. Also (and most importantly) it is inexpensive to create renewable energy. Check the following link for more info and let me know what you thought of it.

Green Living Design you can adopt

Interior Design is the single best experience in my life that has allowed me to experience fantastic creative energy each and every day. I must admit, however, that the move towards "Green Living Design" sometimes has me pulling my hair out.
Don't get me wrong, I've written many an article about the coming boon in Green Living Design and how we, as Designers, must be at the forefront of the movement. With that being said, I find that many of my clients often look at me with that "Deer in the headlight" look when I even casually mention the Green aspect of a Design element for their new home or addition.

It is not that most folks don't care; They do. It is that most feel that they are being handed a bill of goods because something is trendy or fashionable at the moment and can not have any direct implications on their lives in the present. "Going Green" is something that the Hollywood crowd does, not the average consumer.

That used to be true and, yes, in some quarters of "Green Design, " it still is. However, I have found that there are common elements that, if mentioned correctly, everybody can get behind from a Green standpoint.

So, what are the basic elements of some solid Green Living Design that most can see using in their lives? I will touch on four that if you are remodeling or building, can be done in that part of the design; Heating/Air units, HVAC, Wall design, Insulation elements and, finally, Door and Window design elements.

There has been an emergence of systems that use a "Forced Air" feature known as radiant space heaters. Many builders like the aspect of forced heating in that it eliminates a huge chunk of the duct work that must be used in a home design. Some builders, and many fire departments, like the aspect of a lower amount of duct work as it sometimes can aid in the spread of fires in a home.

Wall design has become something of interest, as of late, with the rising cost in energy prices. A lot of builders are liking the idea of walls that are a bit thicker in an exterior build. Many are looking at 12-inch-thick exterior walls with a high R value, which is the rating given a substance's thermal resistance. That gives you better energy values, and combined with better Green materials that go inside the walls, this could save a homeowner substantial money in overall energy cost.

Insulation elements continue to increase in the "Green" factor with some great cellulose insulation options available to consumers. Some of these ratings are as high as R-60, in some cases, and can greatly reduce the cost of running your home when it comes to energy.

Finally, doors and windows. This category is the one that seems to get the lease resistance from homeowners looking at new design elements. It seems that the industry has really taken the lead in this category by just explaining to the consumer, in terms that make total sense, that these design features can and will save them money. It seems that most homeowners have had a face-to-face confrontation with the dastardly windows and doors in their homes and immediately "Get it" when it comes to dealing with them. Still, some of the better energy saving features come at a price and can make many a home owner grimace when handed the bill.

So, there you are. Four design elements that are loaded with "Green Value," as I like to call it. Excellent ways to be a little more conscious about the environment in any Interior Design elements that you are considering and will help you move towards that ever elusive Green Living Design.

Carbon Trading


A lot of big iconic enterprises, like PEPSI, GM, Ford, etc. are spending billions of dollars to go "green". There is a system called Carbon Trading and what it basically is is you become a green consultant and you help your clients go "green" by meeting their needs such as Carbon Credits Green Tags or Renewable Energy Certificates (RECs). I took a look at it and it seems interesting for two reasons: one, it is proof that our world is actually doing something to become more and more environmentally friendly; and two, you can profit from something by doing your part as a green consultant. Just give it a look and post your comments! Here's the link:

What is Engineering Psychology?


In a few words, Engineering Psychology is a part of Ergonomics and it studies the relationship between humans and machines to ameliorate and facilitate the former's lives. It is a program that is not widely known and therefore not offered in many Post-Secondary Schools. In fact the only one I saw offering such a program is Georgia Tech:

Concept of a Green Building


That is what I vision as a Green Building. It has to be one with nature - a sort of symbiotic relationship - where one requires the other.

Welcome!

Hello.

I would like to welcome you all to Green Technology and Architecture. This is my first time creating a blog, therefore any suggestions would be more than welcome and greatly appreciated. My vision for this site is to promote general ideas and concepts (including images, articles, links) concerning Green Architecture (or Eco-Tech), Psychology Engineering (the study of the relationship between human and machine elements to improve overall system performance) and Green Technology.
I will often post images, links and articles. I would also like to have a discussion board where we can share our thoughts about a Green future.

Hope you enjoy the site!

Antonio
