Exolation - New Insulation developed in Philadelphia for newly created End Row Homes




Newly Created "end unit" row homwPhiladelphia is a city of row houses ... unfortunately many are in blighted condition and when they are town down the newly  created "end units" are poorly insulated.  Cleaning up the blighted homes causes the other homeowners to have basically little or no insulation on a large surface of their home.

Exolation insulation

"In the interest of creating local green jobs, the city hopes to find a local manufacturer." " ... product consists of layers of insulating foam (for thermal protection), high-density foam (to absorb impact), fabric (to prevent penetration of sharp objects), and a latex-stucco finish.  ... produce it in 2-by-4-foot panels that will be affixed to a wall with a foaming adhesive."

" ... Philadelphia University's help was enlisted after the city determined that existing exterior-wrap products were too expensive and not sufficiently durable."

Largest Solar Project in Cali




Southern California Edison collaborates with BrightSource Energy to add 1,300 megawatts of solar thermal power capacity to its renewable energy portfolio. BrightSource brings the solar thermal technology to the project, which leverages thousands of mirrors that concentrate sunlight onto a boiler that produces high temperature steam. ...
... "The first of these solar power plants, sized at 100 megawatts and located in Ivanpah, Calif., could be operating in early 2013 and is expected to produce 286,000 megawatt-hours of renewable electricity per year. BrightSource will build and place in commercial operation each of its plants as quickly as permitting and infrastructure allow. The full 1,300 megawatts of projects will produce 3.7 billion kilowatt-hours of clean energy and avoid more than two million tons of carbon dioxide emissions annually – the equivalent of removing more than 335,000 cars from the road. " ...

Recycling Waste Heat




Waste heat recovery is the process of taking the heat from a heat emitting piece of equipment, like a computer, and using it for heating something else - rather than just dissipating it to the environment ... and potentially saving the cost of air conditioning.

"... waste heat recovery, an energy efficiency technique that languishes in obscurity despite its potentially huge environmental benefits. ... in a move that will save money and cut carbon emissions, the University of Notre Dame in Indiana has begun housing some of its computer servers in the nearby “Arizona Desert Dome,” a conservatory for cacti and other desert plants.

"Computer servers create a lot of waste heat ... keeping them cool is a major cost ... for data centers. ... Housing servers in the desert dome, where air currents can carry away their waste heat, is expected to save the university about $100,000 in cooling costs. Meanwhile, the city will save some of the $70,000 it spends each year to keep the conservatory warm. ..."

"Recycled waste heat presents one of the biggest, cheapest opportunities for slashing our carbon budget. ..."

Green Buillding - Adam Joseph Lewis Center for Environmental Studies - Oberlin College




Adam Lewis Joseph Center for Environmental Studies - Oberlin College

What can be accomplished in a Green Building?? 

Oberlin College, Oberlin, Ohio,  takes a careful look ...

>>> Their Adam Joseph Lewis Center for Environmental Studies is detailed below ...

"... was conceived as a demonstration project, ... designed to be a building that would teach. Lessons embodied in its technology and design choices are intended to reinforce those taught in its classrooms. ... "

"...Efforts to research the AJLC's evolution are well underway, providing ongoing opportunities to educate a variety of audiences, including Oberlin College students, regional kindergarten through high school students, other university students and faculty, architecture and design professionals, and lay audiences."

"With over 150 environmental sensors installed throughout the building and landscape, the AJLC's data monitoring and display system provides a unique opportunity to visualize in real-time the flows of energy and cycling of matter that are necessary to support the built environment. ... premise of this work is that real-time feedback on ecological performance increases awareness, ... feedback of this type may be a necessary prerequisite for facilitating a more sustainable relationship among humans, technology and the natural world."

 
Some building details ...

 
 
"Energy - Photovoltaic (PV) panels on the roof ... meet a substantial fraction of the building's energy needs. Solar energy production is coupled with energy efficient lighting, heating, and appliances to minimize negative environmental impact."



 
 
"Heating, Cooling & Air Quality - ... both active and passive systems, ...provides a comfortable working environment ... Active systems use mechanical equipment to extract and move heat, while passive systems do so with a minimum of mechanical devices."



 
 
"Landscape - ... landscape features a variety of constructed ecosystems that simulate native Northern Ohio ecosystems and incorporate cultigens that produce food for humans."



 
 
"Living Machine & Water Use - ... is an ecologically engineered system that combines elements of conventional wastewater technology with the purification processes of wetland ecosystems to treat and recycle the building's wastewater for reuse in the toilets and landscape."



 
 
"Weather Conditions - A weather station ... monitoring real-time conditions and trends for a variety of environmental variables."



 
 "
Materials - Materials ... elected to enhance its sustainability and were evaluated based on criteria that required less energy inputs, encouraged local production and distribution, and supported creative economic structures."

Geothermal Energy Primer




dry steam geothermal

There's energy in them rocks!  

Thermal (heat) energy in deep rock can be used to generate steam that in turn can be used to generate electricity. 

>>> And best of all it is virtually unlimited .... as long as the earth has a molten core.

Currently GEOTHERMAL is the 3rd largerst source of renewable energy in the United States 

"There are three geothermal power plant technologies being used to convert hydrothermal fluids to electricity. ...dry steam, flash and binary cycle. The type of conversion used depends on the state of the fluid (whether steam or water) and its temperature. "

Flash Steram Geothermal

 

"The Earth's magma and hot dry rock will provide cheap, clean, and almost unlimited energy as soon as we develop the technology to use them. In the meantime, because they're so abundant, moderate-temperature sites running binary-cycle power plants will be the most common electricity producers."binary geothermal

"Before geothermal electricity can be considered a key element of the U.S. energy infrastructure, it must become cost-competitive with traditional forms of energy. The U.S. Department of Energy is working with the geothermal industry to achieve $0.03 to $0.05 per kilowatt-hour. We believe the result will be about 15,000 megawatts of new capacity within the next decade."
