April 26, 2010 Science at the Theater: Learn about three efforts our grandchildren may thank us for: cheap solar energy, bringing energy efficiency to China, and learning how to store carbon deep underground.
Can solar energy be dirt cheap?
We're all potentially billionaires when it comes to solar energy. The trick is learning how to convert sunlight to electricity using cheap and plentiful materials. Ramamoorthy Ramesh, an innovative materials scientist at Berkeley Lab, will discuss how he and other researchers are working to make photovoltaic cells using the most abundant elements in the Earth's crust -- materials that are literally as common as dirt.
Energy efficiency in China
Nan Zhou is a researcher with Berkeley Labs China Energy Group. She will speak about Chinas energy use and the policies that have been implemented to increase energy efficiency and reduce CO2 emission growth. Her work focuses on building China's capacity to evaluate, adopt and implement low-carbon development strategies. Zhou has an architecture degree from China, and a Master and Ph.D. in Engineering from Japan.
Understanding geologic carbon sequestration
Even with continued growth of renewable energy sources such as wind and solar, fossil fuels will likely remain cheap and plentiful for decades to come. Geologist Curt Oldenburg, who heads Berkeley Lab's Geologic Carbon Sequestration Program, will discuss a strategy to reduce carbon emissions from coal and natural gas. It involves pumping compressed CO2 captured from large stationary sources into underground rock formations that can store it for geological time scales.

Energy efficiency,lower heating bills and lower consumption of fuel or electricity in historic buildings can be achieved the old fashioned way with simple storm windows that are custom fit and properly fitted over older windows. This process salvages original historic fabric and preserves the aesthetic look of early designs; it also conserves the energy and artisanal labor embodied in the crafting of the original windows. The Jay Heritage Center received 2 grants - one for $25,000 to fund capital improvements to the 1907 Van Norden Carriage House and another from Con Edison to create educational programs around the implementation of these measures - these are teachable moments about energy efficiency and adaptive reuse of historic structures.
Step 10: Installed
Storm windows are a second layer of window. They reduce air movement in and out of the existing windows. They give you an extra barrier to keep out wind and cold in the winter. According to the US Department of Energy, storm windows can help better insulate a home and reduce heating loss by up to 50%.

River Dargle Flood Defence Scheme.
These images were taken during the 2nd week of September, 2017.
The levels of activity have fluctuated along this stretch of the riverbank, and especially around the Irish Rail bridge, informed by the tides and priorities.
Since Summer 2016, this is where the heavy-duty engineering works have been taking place.
This is a section of the flood protection scheme that I have not covered in detail -- it's inconvenient for me to access, and others cover it much better.
Standing on the new riverside walkway alongside Seapoint Court, we could see construction activity sited along the Ravenswell Road, temporarily closed due to on-going works.
That was the site of the old Bray Golf Club -- hotly contested as a (potentially) poorly considered as a site for a shopping centre development complex, and still an area of ground that has to act as a flood plain in the event of tidal surges.
As well as raising a heightened flood protection wall, they've created an access ramp down to the riverside.
The area in the background, site of the old Bray Golf course, was both a works compound and vehicle route for the transportation of material to/from the other sectors along the River Dargle involved in construction works.
By now, most of the heavy works have been completed.
Along the Ravenswell Strip, the guys are now accessorising the wall, creating viewing platforms along this ('to be') pedestrianised walkway.
=========================================================
Between Bray Bridge and the Railway Bridge there was a wooden footbridge linking Ravenswell Road and the Seapoint Road, this bridge was built at the time of the railway coming to Bray.
It closed in 1870 and was removed shortly afterwards.
"The Little Book of Bray and Enniskerry" by Brian White.
==========================================================
The Irish Rail Bridge, Bray Harbour:
Phase 1 flood defence works to the Irish Rail bridge commenced in August 2016.
Phase 2 flood defence works will be completed during May to September 2017. This work is being undertaken directly by Irish Rail.
The work includes strengthening the integrity of the bridge by creating buttresses around the base of each pillar.
To do this they have to pile-drive sheets into the river bedrock.
The work is complicated by;
(a) the need not to damage or disturb in any way the actual bridge itself (Irish Rail train and DART carriages pass overhead on an hourly basis), (b) the confined spaces under the bridge, and (c) the twice-daily rising tides from Bray Harbour which spill upriver into the newly expanded basin.
The length of the Ravenswell Road is to be landscaped into a pedestrian 'experience', with plants, seating and viewing points created in the sea-wall. I think this might link up with a new road and pathway being constructed around to Little Bray.
Through the past few weeks/months, we can see the construction in and around the Irish Rail bridge, where new and extensive reinforced concrete collars are built up to support the existing support pillars/piers. The river and sea beds are also engineered to control the flow of tides and river flows.
For all the convenience, speed and efficiency that modern machinery offers, the scale and nature of this specialised construction works still requires the team of workers to get down and 'hands-on' with the river-bed and the associated fittings that go to shape the upgraded flood defence works.
Arizona Daily Star Article-From ground up, new home is model of energy efficiency....By Dan Sorenson Arizona Daily Star
At first glance, there's nothing about this new 2,000-square-foot house in Civano, other than a rooftop solar panel, to suggest it's unusual. But an occupant would get the picture, in vivid green, when the laughable utility bills arrived.
The ultra-energy-efficient home uses state-of-the-art materials and techniques to cut energy consumption to one-fifth that of a new home built to current building codes, according to Richard Barna, director of building sciences and green building for Pepper Viner Homes.
Known as the Pepper Viner/BASF High-Performance Home, it is a collaboration between the local home builder and BASF, an international chemical and building materials firm. It combines state-of-the-art insulation, solar water and space heating, building materials that don't give off noxious gases, a vapor barrier under the slab, recycled tile, and graywater and rainwater conservation systems.
The house on Tucson's southeast side will be open for a public tour at Civano North Ridge today. But many of the features are not readily apparent.
The house's SIPS (Structural Insulated Panels) modular-wall construction system virtually eliminates leaks and attains a near R-30 insulation rating, according to Barna. The modular system uses large sections of polystyrene sandwiched between sustainable wafer board for exterior walls. Window and door openings are pre-cut at the factory to builder specifications. But Barna said the SIPS walls look like ordinary 2x6 stud walls.
One of the two new types of BASF foam insulation used in the demonstration house may soon offer a solution for old desert houses with inadequate roof insulation, Barna said.
The spray-on insulation has a hard surface — hard enough to walk upon — and a soft open-cell interior. So it could be sprayed on top of an old flat roof, instead of removing the old roof and installing four or six inches of new insulation between the joists or rafters. It would save the cost of removing and replacing the old roof, and provide better insulation, Barna said. It is not yet available locally.
The house also uses all nontoxic materials — adhesives, sealants and wood composites for cabinets — and will meet the new federal interior air standards.
The floors are all polished and dyed concrete. The concrete uses roughly twice the normal amount of fly ash, a recycled material used to replace cement in concrete.
Outside the house the landscaping uses a rainwater collection system hooked up to an automatic watering system that is tied into a weather network that bases watering times and amounts on weather conditions. Trees are watered using an active graywater system that pumps water from drains and sinks to a network of pipes two to three feet underground, to deep-water trees. The graywater isn't collected and held, eliminating storage problems, but is used as soon as it is detected in the system, Barna said.
Bill Viner of Pepper Viner said some of the technologies and building materials are already in use, and that he expects more will be in demand, and supplied, when the housing industry picks up after the recession.
"Not only will there be greater demand, but I think the builders will do it because it's the right thing to do," Viner said.
He wouldn't estimate the house's value, or what it would cost to reproduce it, but he said a similar floor plan house in Civano North Ridge development sells for $299,900.
And he said other houses in the development already use some of the methods to meet a standard based on heating and cooling costs-savings of at least 50 percent of that of a conventional home.
Viner said the demonstration home is under consideration for the top (platinum) rating in the national green building certification system, LEED. And he said it was already awarded the Pima County certification system's top (emerald) rating.
Sustainable college housing in Rock Springs, WY
When the 2008/2009 school year kicked off at the Western Wyoming Community College (Western) in Rock Springs, WY this fall, students were greeted by a new state-of-the-art, 28,000-square-foot housing complex that features 48 bedrooms spread throughout four stories. Wind River Hall has everything a college student could ask for, including 12 individual bedrooms, six fully functional kitchens and three spacious living rooms per floor.
Before Wind River Hall was designed, extensive research was conducted at institutions throughout the United States to determine student preferences regarding residence hall room arrangements. “Many students expressed the desire to be social yet also have the opportunity for privacy. Wind River Hall is designed with these wants in mind,” said Jon Schrade, Western’s Director of Housing and Student Activities.
While Wind River Hall meets the need for both social and private spaces through a spacious layout, it is the building’s innovative construction that truly makes it unique. Framed entirely out of structural insulated panels (SIPs) manufactured by Premier Building Systems in Fife, WA, Wind River Hall is the tallest self-supporting SIPs structure ever built.
Consisting of an expanded polystyrene (EPS) insulation core sandwiched between two layers of oriented strand board (OSB), SIPs are a dependable, cost-effective building solution that address four issues on the minds of virtually every school official involved in the construction process – energy efficiency, lifecycle costs and both environmental and indoor air quality.
Energy Efficiency
Buildings account for nearly 30% of all energy consumption in the United States. As oil and gas prices continue to rise, many publicly funded schools are experiencing higher than expected heating and cooling costs that are cutting into their delicate budgets.
SIPs are used in lieu of traditional framing materials such as wood and steel studs. Studies conducted by the Oak Ridge National Laboratory in Oak Ridge, TN, have shown that SIPs can help reduce a building’s annual energy costs by 50% - 60% when compared to more common framing methods.
Because of their energy efficiency, SIPs are also recognized by a number of governmental groups, including the Environmental Protection Agency (EPA) and the Department of Energy (DOE). The ENERGY STAR® program, administered by the EPA, has waived the need for a blower door test on any building constructed with SIPs. DOE officials have also said that the $2,000 Federal Energy Tax Credit is virtually impossible to gain without SIPs.
Lifecycle Costs
While energy savings are the most obvious benefit of using SIPs, this product also provides numerous other opportunities for building owners to improve their return on investment by reducing a building’s lifecycle costs.
SIPs are prefabricated to the exact specifications of a project and delivered to the jobsite ready to install. This results in a more efficient installation and helps eliminate the costly removal of construction waste. SIPs are also easier and more efficient to install than competitive systems, reducing construction time and minimizing labor costs.
In addition to enhanced time and energy savings, SIPs provide more strength and durability than stick- and steel-framed buildings. The increased durability is ideal for college environments, where students often take advantage of their newfound independence by turning campus buildings into their own personal punching bags. With SIPs, colleges get a dependable, long-lasting structure that can withstand constant abuse.
SIPs may also allow for a reduction in the size of a building’s HVAC equipment by up to 40%, which means lower upfront costs for equipment purchases and a reduction in future maintenance costs.
Environmentally Conscious
Colleges are increasingly turning to green building practices as a way to entice new students, reduce their carbon footprints and receive government grants, subsidies and tax incentives.
By utilizing SIPs, buildings can earn up to 23 points within the LEED Green Building Rating System™, the nation’s predominant green building program administered by the United States Green Building Council. SIPs also contribute to the $2,000 Federal Energy Tax Incentive, as well as a number of other tax programs that can help put money back into a university’s budget.
Improved Indoor Air Quality
The EPA lists poor indoor air quality as the fourth-largest environmental threat to our country, a problem that is often overlooked during the construction process. Recent studies indicate that poor indoor air quality can have significant effects on respiratory illnesses as well as the overall health, achievement and productivity of a building’s occupants.
The best way to mitigate the causes of poor indoor air quality is to create an airtight building envelope. The airtight nature of SIPs helps improve indoor air quality and reduce unwanted air transfer by reducing gaps in the building envelope.
An unsealed building envelope allows unwanted infiltration of common pollutants such as radon, molds, pollen, VOC’s, lead dust and asbestos. By using SIPs to protect the indoor environment from these toxins, colleges can improve the health of their student body while providing them with the best possible atmosphere for educational success.

May 10, 2010 Science at the Theater: The House of the Future.
See what it will take to create tomorrow's net-zero energy home as scientists reveal the secrets of cool roofs, smart windows, and computer-driven energy control systems.
The net-zero energy home
Scientists are working to make tomorrow's homes more than just energy efficient -- they want them to be zero energy. Iain Walker, a scientist in the Lab's Energy Performance of Buildings Group, will discuss what it takes to develop net-zero energy houses that generate as much energy as they use through highly aggressive energy efficiency and on-site renewable energy generation.
Talking back to the grid
Imagine programming your house to use less energy if the electricity grid is full or price are high. Mary Ann Piette, deputy director of Berkeley Lab's building technology department and director of the Lab's Demand Response Research Center, will discuss how new technologies are enabling buildings to listen to the grid and automatically change their thermostat settings or lighting loads, among other demands, in response to fluctuating electricity prices.
The networked (and energy efficient) house
In the future, your home's lights, climate control devices, computers, windows, and appliances could be controlled via a sophisticated digital network. If it's plugged in, it'll be connected. Bruce Nordman, an energy scientist in Berkeley Lab's Energy End-Use Forecasting group, will discuss how he and other scientists are working to ensure these networks help homeowners save energy.
