The American Recovery and Reinvestment Act (ARRA) signed into law by President Obama in February provides financial opportunities for homeowners, specifically tax credits, rebates, and loans for improving energy efficiency. The Act also provides tax credits for buying a house and for hybrid and alternative fuel car purchases. The problem is that the 400 page legislation can be tough to work your way through to find what’s available to you.

The Sears Tower loomed large during my childhood in the Chicago suburbs. I remember when it opened in 1973. We took a special trip downtown to see it. According to my aesthetics as a seven year old, it wasn’t very elegant and I preferred the John Hancock Tower with its swanky restaurant on the 95th floor and proximity to Marshall Fields. Then the company my dad worked for was bought by Coldwell Banker, a subsidiary of Sears at the time, and his office was moved to the Tower. I spent some quality daddy-daughter time there, and one memorable summer got paid the incredibly generous sum of $8 an hour to take the train to the city every day, do some filing and hang out downtown.
But the Tower, in my mind, never had much to distinguish it other than a great view from the 103rd floor, its height of 110 stories and the convenience of the train station. But now everything is changing.
By the end of the summer, it will no longer be the Sears Tower. It will be called the Willis Tower, named for the global insurance broker. But more importantly, the building will undergo a $350 million efficiency and renewable energy retrofit that will reduce the base building electricity use by up to 80 percent - 68 million kilowatt hours annually or 150,000 barrels of oil every year. The retrofit will also create more than 3,600 jobs in the Chicago area.

Given the climate change coming to most regions of the US, this new roof idea is a great passive cooling solution worth looking at even if you don’t live in the desert regions… now.
Because, by century’s end; you might.
“Summer temperatures in Florida could rise by 10.5F, with the heat effect multiplied by decreased rainfall under the higher emissions scenario. There would be increased hurricane intensity and rising sea levels leads to loss of wetlands and coastal areas.”
“When you’re out in the desert, shade is gold. It’s the most valuable asset you have, so to make more shade was [the] strategy,” says Lloyd Russell of this house he designed to withstand both the scorching heat and the cold of the desert for a client in Southern California.
Russell’s very low carbon way to cool a home is another example of how creatively some architects are thinking out of the box and in the process creating an entirely new design vernacular - architecture for zero energy use in a carbon-constrained, hotter, wilder new world.

Evening Breeze sustainable bedIt’s summer in the Northern hemisphere, and for many, that means going on holiday to warm, tropical locales. And using air conditioning. Lots of it. In fact, in some tropical places, nearly 80% of energy use in a hotel room is for air conditioning. 1200 to 2000 watts on average.
Evening Breeze is an interesting solution: It’s a canopy bed that has adjustments for both temperature and humidity, and delivers it quietly, overhead, using only 400 watts. As [...]

As U.S. policymakers debate the best renewable policy for the country, many German experts are already convinced they know the answer: a feed-in tariff. Germany’s feed-in tariff, which offers generous set prices for renewable electricity fed into the grid, stimulated 1.5 gigawatts of new solar capacity last year, and similar programs also have boosted markets in countries such as Spain, Greece, Italy, Turkey and South Korea. All the fastest-growing solar markets in the world today have feed-in tariffs.
Gainesville, Fla., and Ontario, Canada, also recently created German-style feed-in tariffs, but the policy hasn’t yet taken hold as a U.S. state or federal policy. I recently wrote a post for Earth2Tech about the difficulties of implementing a German-style feed-in tariff in California: the policy isn’t responsive to market signals that would encourage electricity generation when and where it’s most needed, it’s more challenging to make work in places with lower conventional electricity prices and widely varying utilities with different restrictions, and it doesn’t address retail electricity or encourage customers to use less energy.
a broad coalition of consumer, economic and environmental advocacy groups has published a report on the substantial consumer savings that stronger energy efficiency and renewable energy standards would bring.

Goes one further….
If every building had a white roof, we would be able to cool the surrounding areas. That is the reasoning behind a California law about to go into effect next month requiring light reflective roofs on all new buildings. It is already the law for new flat roofs here.

This is design that respects the users time. There’s no need for a 30 page manual in 12 languages to do 3001 pointless things with this gizmo that you don’t have time to do anyway. It’s simple. Technology does not have to be a time sink.

We are seeing more climate conscious design in architecture: In this case; the rain screen.
A skin over the house is designed to manage and harvest occasional heavy precipitation, to provide protection from premature decay from moisture intrusion.

When it comes to environmental news, doom and gloom often rules the day. And it’s easy to get discouraged. But scientists from Yale University say most polluted ecosystems can recover in as little as 5 or 10 years.
The study means it’s not too late to turn things around if societies commit to cleanup, restoration and sustainability, according to Yale’s analysis of 240 independent studies. The findings appear in this month’s issue of the peer-reviewed journal PLoS ONE.

In a surprising find, scientists have discovered a microbe that can efficiently convert direct electrical current into methane.
That may be good news for wind and solar power enthusiasts, who have long been faced with the dilemma of how to store energy when the wind isn’t blowing and the sun isn’t shining. This discovery opens the door for generating methane from those renewable power sources; the energy could then be stored as fuel for later use.
But is storing renewable energy in the form of a greenhouse gas like methane a solution, or just another problem?
