first_imgNAPA — Richie Incognito didn’t look or sound unhinged. He was forthright, direct and sounded greatly appreciative of a last chance afforded by general manager Mike Mayock and Jon Gruden.“I think for so many years I’ve just done this thing where I grit my teeth and work hard, just kind of grind through this,” Incognito said Saturday following the Raiders’ first training camp practice. “You’ve obviously seen I’ve had my setbacks and some dark days. But I’m focusing on these positive days and …last_img read more

first_imgOnly photos and the blueprints remainI visited Dr. Löf at the house just a few months before his death. He was bright, and we had a long conversation.He gave me the original set of blueprints to the house, and I suspect, sadly, that he recognized that the drawings wouldn’t be needed by the next owners of the property. In the 1970s, the George Löf house was frequently hailed for having the oldest continuously operating active solar heating system in the world. Löf lived in the home until his death in October 2009 at the age of 95. (For more information on George Löf, see my book, The Solar House: Pioneering Sustainable Design, or George Löf: Denver’s Solar Pioneer. A February 1958 magazine article on the George Löf house is available online: “Will Your Next House Get Its Heat from the Sun?”) RELATED ARTICLES Solar Versus Superinsulation: A 30-Year-Old DebateForgotten Pioneers of Energy EfficiencyThe History of Superinsulated Houses in North AmericaShades of Green: the 1970s vs. the Millennial Generation Present at the creationNobody played a more enduring role in the 20th-century solar house movement than George Löf. He was present at the creation, so to speak, having been a student of Hoyt Hottel when Hottel built the first-ever “active” solar thermal house at MIT in 1939. In 1945, Löf built the first active solar air system, a precursor to the system installed in the Denver house. He would remain active in the field for decades, and served a term as president of the International Solar Energy Society. A tear-downPrior to the demolition, the Löf house was in original condition, including the flat-plate solar collectors (air heaters) on the roof. It had hardly been touched since its construction 57 years ago: not even a coat of paint in my estimation. Image #2 (below) shows how the Löf house looked when I visited it in September 2011.At that time (two years after Löf’s death), the house was vacant and for sale. Because of the large size of the lot, the condition of the house, and the (wealthy) neighborhood, it was predictable that the house would be purchased as a tear-down. At that time I contacted the realtor and local preservation groups to make sure that the house’s importance was understood, but obviously to no avail.As I document and discuss in great detail in my book, the Löf house was remarkable for its technical innovation and for the sympathetic relationship between the architects (James Hunter of Boulder, assisted by Tician Papachristou) and the engineer (Löf). The design was celebrated by the New York Times for its heating system and Hunter’s “modern lines.”The rooftop collectors, still in place in 2011 and just barely visible behind plywood screens, produced hot air which could be sent straight to the rooms of the house or to gravel tubes that were used to store the heat. The sympathy between architecture and engineering was expressed most beautifully by Hunter’s decision to place the cardboard tubes near the staircase in the center of the house, visible from the entrance, and to paint them bright red. (And in a wonderfully poetic contrast he formed a concrete chimney from the same type of cardboard tube, and painted the chimney a cool blue.) Here is some sad but not surprising news: the George Löf house — one of the seminal buildings in the history of the solar house and certainly a modernist landmark worthy of protection and preservation — was recently destroyed. I visited the Denver site earlier this year and found a large excavation and a foundation (presumably) for a McMansion.Most of us associate the term “solar house” with the 1973 energy crisis. But the feasibility of solar houses in the 1970s would have been impossible without the earlier exploratory work by pioneers such as George Löf. The house Löf built for himself in Denver, in 1955-56, was a seminal experiment in solar heating, using an innovative system of rooftop collectors, solar-heated air, and gravel storage. It “became a model for emerging solar home heating systems and attracted engineers from around the world,” according to the Wall Street Journal.
