EnergyPlus Software Named "Best Invention of the Year" by Time Magazine

Friday, November 30, 2007

Time Magazine has named the San Francisco Federal Building one of its 2007 "Best Inventions of the Year" winners in the architecture category. Its citation noted that the building is "really a machine for delivering sunlight and fresh air to the people who work there." EnergyPlus was used to model the building's energy efficiency features.

The Pioneer of Energy Simulation. "Gint" Mitalas

Thursday, November 29, 2007

We have all heard of Willis Haviland Carrier as the engineer and inventor, and who is known as the man who invented modern air conditioning. At the age of 25, he devised his first important invention, a system to control heat and humidity for the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, and was eventually made the head of the Buffalo Forge subsidiary named Carrier Air Conditioning Company in his honor.

Not many may have heard of Gintautas “Gint” Povilas Mitalas.

Gint was born in Lithuania in April 1928. In 1953 he went to the University of Toronto to study mechanical engineering, graduating with a BASc in 1957 and an MSc in 1959. Gint joined the staff of the National Research Council of Canada in 1959 to work in the Division of Building Research, where he was part of a small group that was exploring ways to improve the accuracy of the calculation of heat transfer through walls. In the early 1960s he used an analog computer to simulate the heat flow through walls and roofs. Later he shifted his effort to using digital computers for calculating heat gain through walls and roofs. This led to the Response Factor approach, and finally to the Z -Transfer Function method that was adopted by ASHRAE. He became a member of ASHRAE in 1966.

Gint presented two papers at the highly successful “First international symposium on the use of computers for environmental engineering related to buildings” that was held in Washington, DC in 1970.

IBPSA makes awards for outstanding work in the building performance simulation field. It was first awarded in 1991 to Gint Mitalas for his outstanding service and lifetime accomplishments in building simulation.

He passed away in Ottawa, Canada on 13 May 2005.

Gint shall be remembered for his pioneering work on energy simulation which has lead to the current revolution in whole building energy simulation software.

EnergyPlus, SketchUp, Google Earth, India and China

With the release of EnergyPlus 2.1, there's been a very interesting announcement in connection with Google SketchUp and the weather data convertor, which now produces KML output for Google Earth.

A beta version of building simulation within SketchUp is planned n the next few weeks. In the first release in early 2008, users will be able to draw their building, paint the surfaces with thermophysical properties, select default building type information, schedules, and HVAC systems, and simulate the energy performance of their building — all within SketchUp.

WeatherConverter now produces KML output (for Google Earth) of latitude, longitude, elevation, and a few climate statistics for locations in a list processing run.

Several other interfaces are under development—including two from China and India. These are likely to be announced shortly on;

EnergyPlus V 2.1 is now available at no cost from the EnergyPlus web site

Google Expands Into Alternative Energy

Wednesday, November 28, 2007

As part of a project announced Tuesday, the Internet search leader and its philanthropic arm will pour hundreds of millions of dollars into a quest to lower the cost of producing electricity from renewable energy sources such as wind and the sun.

If Google realizes its goal, the cost of solar power should fall by 25 to 50 percent, co-founder Larry Page said in an interview.

"If we achieve these goals, we are going to be in the (electricity) business in a very big way," Page said. "We should be able to make a lot of money from this."

How costs of sustainable Energy Development can be cut in half

Wednesday, November 14, 2007

Ellen Brown, November 5th, 2007

"During the recent bank credit crisis in August 2007, the central banks of the United States, Europe, Canada, Australia and Japan collectively extended a $315 billion credit line to commercial banks. This credit was created out of nothing – something central banks assume the right to do as "lenders of last resort" – and the sums advanced were huge.6 For comparative purposes, a mere $188 billion would have been enough to repair all of the 74,000 U.S. bridges known to be defective, preventing another disaster like that in Minnesota in July 2007. The Carbon Trust, a well-known UK company dedicated to cutting carbon emissions, is responsible for reducing emissions by nearly 2 million tons per year on a 2007 budget of only £115.9 million (about $240 million U.S.). If central banks can create hundreds of billions of dollars to save floundering private banks, governments can create comparable credits to adapt to climate change, an even more pressing problem."

The deceit behind global warming

Monday, November 5, 2007

By Christopher Booker and Richard North

"Mann's hockey stick was just what the IPCC wanted. When its 2001 report came out it was given pride of place at the top of page 1. The Mediaeval Warming, the Little Ice Age, the 20th century Little Cooling, when CO2 had already been rising, all had been wiped away.

But then a growing number of academics began to raise doubts about Mann and his graph. This culminated in 2003 with a devastating study by two Canadians showing how Mann had not only ignored most of the evidence before him but had used an algorithm that would produce a hockey stick graph whatever evidence was fed into the computer. When this was removed, the graph re-emerged just as it had looked before, showing the Middle Ages as hotter than today.

It is hard to recall any scientific thesis ever being so comprehensively discredited as the "hockey stick". Yet the global warming juggernaut rolled on regardless, now led by the European Union. In 2004, thanks to a highly dubious deal between the EU and Putin's Russia, stage four of the story began when the Kyoto treaty was finally ratified."

"If global warming does turn out to have been a scare like all the others, it will certainly represent as great a collective flight from reality as history has ever recorded. The evidence of the next 10 years will be very interesting." End of Post

Blondes and global warming

Saturday, November 3, 2007

Last year I replaced all the windows in my house with that expensive double-pane energy efficient kind, and then today, I got a call from the contractor who installed them. He was complaining that the work had been completed a whole year ago and I still hadn't paid for them. Hellloooo,...........just because I'm blonde doesn't mean that I am automatically stupid. So, I told him just what his fast talking sales guy had told me last year, that in ONE YEAR these windows would pay for themselves! Helllooooo? It's been a year! I told him. There was only silence at the other end of the line, so I finally just hung up. He never called back. Guess I won that stupid argument. I bet he felt like an idiot.
