Ways To Reduce Your Building Site’s Carbon Footprint

Building being demolished

In the 25 years ending in 2005 more than 12.5 million housing units in the US were demolished, damaged beyond use, or taken out of the stock for other reasons. Most of the components of those buildings, whether useful or not, went into landfills. Green building sites will be increasingly looking for ways to reuse and recycle building components.

The principle behind cool roof technology was no doubt born when humans noted the difference between how dark colored substances gathered and held heat compared to light colored substances.  Today, the scientific measurement applied to roofing that relates to this principle is called the Solar Reflectance Index, or SRI. Basically, the index states that a rating of zero defines how black deals with heat, and a rating of 100 defines how white does. When it comes to picking roof coverings, the SDI is one factor to consider when you want to minimize heat gain to help with cooling costs.

Late last year, Kirberg Company announced it had completed the installation of a new “Cool Roof” System at Missouri State University’s Kemper Hall,  in Springfield, Missouri.  The system specified was a Johns Manville product called DynaGlas® FR CR, (fire rated, cool roof). This roofing material has an SRI of 93 right after installation and one of 74, three years later.

According to Kirberg,  cool roof systems like the one installed for Kemper Hall are among the fastest growing commercial roofing systems in the industry. They’re a three-layer product with a cool roof, ceramic coating over top of a layer of fiberglass and a bottom layer of asphalt waterproofing. They are exceptionally resistant to wind and fire, as well as ultraviolet, ozone, and chemical exposure.

The Kemper Hall project is not the first roofing project that Missouri State has hired Kirberg Company to complete. The roof consisted of a total replacement, amounting to 400 squares. Earlier in the summer of 2011, Kirberg replaced the roof on the Plaster Student Union, the gathering and learning center for the students. The materials used for both roofs were Derbigum, a type of roof system that works to save and produce energy.  The student union roof took two weeks to complete, and amounted to 100 squares.

 

Gee, An Energy Efficient Hot Water Heater

It looks like General Electric has made headway in the battle to get electric hot water heaters to be more efficient. The company claims the average homeowner can save about $325 a year by installing its new hybrid hot water heater that uses a heat pump in conjunction with a standard electric resistance element. Gee.

Nearly all Americans (96 percent) think improved appliance efficiency is important for personal financial reasons, yet many homeowners don’t realize the water heater is the second single-biggest, energy-consuming appliance in homes, behind the HVAC system.

GE’s GeoSpring Hybrid Water Heater combines energy-saving heat-pump technology with traditional electric heating systems used in most conventional water heaters on the market today. This hybrid technology is designed to absorb heat in ambient air and transfer it into the water. Since this requires much less energy than the energy used to generate radiant heat – as used in a conventional electric tank water heater – the GeoSpring Hybrid Electric Water Heater is more economical to operate.

Besides saving money, GE’s product general manager for water products, Stephen Downer explains the environmental benefits this way:

Approximately 50 percent of U.S. households use a standard electric water heater. If 25 percent chose a GeoSpring instead of a standard 50-gallon electric water heater, more than four billion pounds of CO2 emissions on the U.S. grid could be avoided annually – equivalent to the annual emissions of more than 360,000 cars on U.S. roads. That’s a powerful way consumers can help the environment.

Other features of the GeoSpring include:

  • It has same footprint and electrical connections as the standard electric water heater, making it easy to install.
  • It provides the same amount of hot water as traditional 50-gallon standard electric water heaters.
  • Its integrated electronics on the control panel offer exclusive features, such as Vacation mode, which will lower the water temperature to 50 degrees for the duration of a trip, and then automatically reenergize itself on the day before the homeowner’s return.
  • It offers more control over water temperature, allowing you to adjust in one degree increments from 100 to 140 degrees Fahrenheit.

State and local tax credits and utility rebates for purchasing the ENERGY STAR-qualified energy-efficient water heater may also be available to benefit consumers.

Pricing and availability

GeoSpring will be available at national retailers in March such as Lowe’s and Sears and national plumbing distributors such as Ferguson as well as many local retailers and distributors. Estimated retail price: $1,199-$1,299. More information on features and availability is right here.

Home Energy Management Program Takes Its Cue From What’s Happening Right Outside Your Window

How about turning over the management of a home’s heating and cooling to a super smart web-based entity? That’s more or less what’s coming down the pike for Texans this summer with implementations planned across the country as more utilities sign on.

Earth NetworksSM the operator of the largest weather, lightning and climate observation networks, andEnergyHub, Inc., a leading provider of home energy management software and systems, announce a new home demand response and energy efficiency program called e5SM. The patent-pending e5 program, which stands for ease, energy, efficiency, environment and earth, incorporates for the first time live, neighborhood-level weather conditions and forecasts into demand response programs that aim to reduce peak consumer demand to better manage grid load during extreme weather. According to Dave Oberholzer, products and business development director for Earth Networks Energy:

“Many utilities are interested in rolling out demand response programs, but user adoption is limited because consumers want to retain control of their thermostat and remain comfortable while saving both energy and money”

The program is designed to provide home energy efficiency without sacrificing comfort, while putting the consumer in control.

Utility Company Opportunities

The e5 program takes the burden off utilities to supply, install and maintain home thermostats because consumers play an active role in the program. When consumers choose to join, they select and install a program-compatible Internet-enabled thermostat that is available at major home improvement retailers and online. The program is launching with the 3M Filtrete™ Wi-Fi-enabled programmable thermostat, which includes EnergyHub’s user-friendly software that guides the consumer through the setup process and provides them with ongoing remote HVAC control.

Based on the consumer’s own selections, the e5 program maintains desired comfort level while optimizing energy use by pre-cooling or pre-heating in response to local weather, and when a demand response event is anticipated by forecasted conditions. Further, the e5 program provides homeowners with a home energy audit, which ranks the efficiency of the house using local weather conditions including temperature, wind and solar fluctuations. From the rankings, e5 provides a customized and prioritized list of recommended steps consumers can take to save energy and reduce costs for their home energy systems, which drive the majority of consumer demand during peak periods.

Uses Local Weather Information

Weather is the largest variable impacting home energy demand. To maximize effectiveness, the e5 program integrates data from more than 8,000 state-of-the-art Earth Networks weather stations installed at schools and public buildings around the country to provide live, hyper-local weather data for a customer’s location. In contrast, other approaches rely on weather data from an often distant location, such as an airport, with delayed reporting that may not represent actual current local conditions.

In developing the e5 program, Earth Networks and EnergyHub sought to overcome a major factor overlooked by many existing demand response programs – occupant comfort. Unlike existing demand response programs that turn off or cycle home thermostats on a pre-defined schedule regardless of the actual indoor temperature, e5 puts the consumer in control. With e5, users dynamically adjust their comfort settings using EnergyHub’s website and mobile apps.

The e5 program is available to all utilities, whether they have existing demand response programs or want to replace their current programs with a more consumer-oriented offering.

Contractors who are building out and improving the country’s metropolitan landscapes don’t have to settle for off-the-shelf transit shelters, street furniture and advertising kiosks. That’s because companies that design and manufacture those fixtures are increasingly turning out custom products that fit the local environment and climate.

One example is Tolar Manufacturing which uses Autodesk Gold Partner KETIV Technologies to design and make more than 500 shelter types within the company’s four main product lines, each designed and engineered to be long-lasting, attractive and environmentally friendly. This includes complying with a wide range of building code requirements across North America and community design requirements from economical transit shelters to high volume bus rapid transit facilities. Tolar client expectations for purpose- driven design range from hurricane-resistant bus shelters for Florida communities to solar-powered transit displays for agencies in California.

On a typical project, Tolar begins by creating 3D models of the proposed shelter using Inventor software. To further communicate design intent to customers, Tolar can create a near-photorealistic image of the model in Showcase software, and then superimpose it over an actual streetscape from the customer’s town, enabling customers to see exactly what Tolar’s product will look like when installed in the community.

Next, the Inventor manufacturing models are used to fabricate the multiple components that make up the shelter. These models provide clear, concise and comprehensive communications, resulting in fewer errors on the shop floor.

Additionally, Tolar uses Vault software to centrally store and manage its digital data, making it easier for the company to access and reuse drawings of specific parts for multiple projects rather than having to start each time from scratch — significantly reducing project turnaround time. Tolar also uses Inventor Publisher software to create installation instructions for customers.

Autodesk named Tolar its Inventor of the Month for January 2012 for how it used Autodesk software to create custom products matching the needs of municipalities throughout North America.

Building Energy-Use Management On The Rise

06-07 Concrete Thinking for a Sustainable World

According to a new report from Pike Research, worldwide revenue from building energy management systems will increase at a compound annual growth rate (CAGR) of nearly 14 percent through the rest of this decade, reaching just under $6 billion a year by 2020.

BEMS include software, hardware, and services associated with the intelligent  monitoring, management, and control of energy, specifically for reducing overall energy consumption and lowering energy costs. It’s no wonder BEMS are on a growth trend as the U.S. Department of Energy, reports that 18 percent of all the energy produced in the United States is used to cool, heat, light, or accomplish other functions within commercial buildings. Eric Bloom, research analyst with Pike also credits advances in these systems for the rosy outlook, saying:

Over the last year, the convergence of building equipment and IT has advanced at a rapid pace, enabling a higher degree of control over building energy and operations than ever before.  The BEMS market is evolving rapidly and is enjoying a burst of innovation, leading to an explosion in the amount of data that is available on the energy performance of commercial buildings.

North America continues to lead the global market for BEMS, but Pike Research expects growth to accelerate worldwide, particularly in Asia Pacific.  While interest in BEMS and energy efficiency is high in Western Europe, Asia Pacific will take its place as the second largest market in coming years, due to the extremely rapid pace of construction in the region as well as the challenge of meeting soaring energy demand with limited supply.  Outside of these three regions, the BEMS market will generally experience single-digit growth and modest levels of overall spending over the forecast period.  In every region, the existing building stock is a large market for BEMS sales – particularly buildings constructed or modernized within the last 30 years with moderately sophisticated building management systems.

Pike Research is a market research and consulting firm that provides in-depth analysis of global clean technology markets.

Getting To Know LEED: The Basics

The Leadership in Energy and Environmental Design is a rating system used for construction, operation and design of green homes, buildings and entire neighborhoods. It was developed by the U.S. Green Building Council so operators and owners would have a framework to guide them in green construction and design methods.

The LEED accredited professional program currently has 10 different rating systems that correspond to types of buildings and types of construction. There are separate scales for new construction, schools, retail, core and shell, healthcare, commercial interior, retail commercial interior, existing building operations and maintenance, neighborhood development, and a separate category exclusive for homes. The system is also integrated with and used as a basis for other well-known rating systems such as the Labs21 by the Environmental Protection Agency.

The rating system consists of 100 different possible points that can be distributed across five major categories including energy and atmosphere, materials and resources, sustainable sites, water efficiency and indoor environmental quality. A score of 40 to 49 classifies a building as certified, 50 to 59 is silver, 60 to 79 is gold and 80 or above earns platinum classification.

LEED buildings are known for using materials more efficiently and for promoting healthier work and living environments, which in turn boost both productivity and comfort levels. A LEED strategy includes a listing of beneficial behaviors that improve both air and water quality while reducing solid waste and benefitting owners and society as a whole.

It’s important to note that LEED is not intended to be used as a way to measure performance. It is a tool that uses its standards and rating system to measure design, which will hopefully lead to better performance and results.

LEED certification does certainly have its benefits in some areas. Some local, state and even the federal government have given incentives to those with gold LEED status. Some areas have given construction materials to the companies, while others provide tax exemptions for being LEED Certified. Other benefits of the status include tax breaks, density bonuses, faster permits and processing and low-cost or even free technical assistance when necessary. It may also increase chances of qualifying for grants or low-interest loans, making it more than worth the effort to go for the gold LEED status.

Why Not Use Hot Water to Cool Buildings?

Mitsubishi's adsorption chiller enters US test-market in February. (Photo: Mitsubishi Plastics, Inc.)

WASHINGTON–(BUSINESS WIRE)–Mitsubishi Plastics, Inc., in collaboration with Union Industry Co., Ltd., has developed an easy-to-install compact adsorption chiller with an integrated cooling tower (cooling capacity of 10 kW). The chiller, which uses the zeolitic water vapor adsorbent AQSOATM, can work with a solar water-heater, making it possible to significantly reduce electricity use and save energy. Mitsubishi Plastics will start test-marketing the chiller to the U.S. market beginning January 23, 2012.

Since 2008, Mitsubishi Plastics (Headquarters: Chuo-ku, Tokyo; President: Hiroshi Yoshida) has been manufacturing parts, such as heat exchangers, coated with AQSOATM, a zeolitic water vapor adsorbent that is able to efficiently release water vapor – even at relatively low temperatures (140?-176?). Since heat exchangers coated with AQSOATM are able to reduce the consumption of energy, the parts are already being used in many adsorption chillers (cooling capacity of 9-350 kW) in Japan and Europe, with the product performance being praised around the world.

Why adsorption chillers?

For economic reasons, air conditioning units using compressors, not adsorption chillers, have traditionally been used in small facilities. However, there is a growing demand across the globe for energy efficient air conditioning units that can reduce CO2 emissions.

To address such issues, Mitsubishi Plastics and Union Industry have developed a compact adsorption chiller, featuring an easy installation process. This compact adsorption chiller can be used for cooling data centers or domestic houses through the use of hot water from solar water heaters and cogeneration systems, or by waste heat from small factories.

When combined with a solar water-heater*, the cooling performance of this product throughout the day will be superior by 50% from that of traditional silica gel adsorption chiller. (The temperature of recycled water is assumed at 149?.)

When the product is combined with a cogeneration system, the system is expected to reduce electricity consumption by up to 20% from that of coolers with compressors (based on Mitsubishi Plastics research). In addition, the superior durability of AQSOATM reduces running costs due to fewer maintenance requirements.

Easy Installations

Furthermore, with the technology of the adsorption chiller developed by Union Industry and the knowledge of cooling towers that Mitsubishi Plastics has long cultivated, for the first time in the world, the adsorption chiller and cooling tower have been integrated, making it significantly easier to install the system in comparison with traditional products.

Mitsubishi Plastics will exhibit this easy-to-install compact adsorption chiller with an integrated cooling tower at the International Air-Conditioning, Heating, Refrigerating Exposition (AHR EXPO) to be held in Chicago from January 23–25, and additionally, will conduct various marketing activities to sell the product to the U.S. market. In certain cases, this enables federal and states tax credits for energy efficiency.

Chinese Prefab Hotel Goes up in 15 Days

Screen Shot 2012-01-20 at 1.09.17 PM

Prefab building in China has just advanced with the erection of a 30 story hotel to completion in just 15 days. The unique building process relies on prefabricated components that are wired, plumbed and finished before they get to the job site.

Not only that, each floor section is raised into place with everything needed to finish it inside and out. Some people claim this is going to further revolutionize construction by advancing the art of prefabrication and also making it possible to easily ship and assemble buildings across the globe.

Here’s a video showing the construction of this hotel.

Solar Breakthrough: Cheap Quantum Dot Solar Paint

Researchers have reduced the preparation time of quantum dot solar cells to less than an hour by changing the form to a one-coat quantum dot solar paint. How?

Titanium dioxide (TiO2) nanoparticles are coated with cadmium sulfide (CdS) or cadmium selenide (CdSe.) The composite nanoparticles, when mixed with a solvent, form a paste that can be applied as one-step paint to a transparent conducting material, which creates electricity when exposed to light.

Efficiency Issues

Although the paint form is currently about five times less efficient than the highest recorded efficiency for the multifilm form, the researchers predict that its efficiency can be improved, which could lead to a simple and economically viable way to prepare solar cells.

The scientists responsible for the research breakthrough, Mathew P. Genovese of the University of Waterloo in Canada, Ian V. Lightcap and Prashant V. Kamat of the Radiation Laboratory and Department of Chemistry and Biochemistry at the University of Notre Dame in Indiana, will be publishing their study in an upcoming issue of the American Chemical Society’s publication “Nano.”

Details, Details

During an interview with PhysOrg.com Professor Kamat, John A. Zahm, professor of science in chemistry and biochemistry, an investigator in Notre Dame’s Center for Nano Science and Technology (NDnano) and the leader of the research, explained:

Quantum dots are semiconductor nanocrystals which exhibit size-dependent optical and electronic properties. In a quantum dot sensitized solar cell, the excitation of semiconductor quantum dot or semiconductor nanocrystal is followed by electron injection into TiO2 nanoparticles. These electrons are then transferred to the collecting electrode surface to generate photocurrent.

The holes that remain in the semiconductor quantum dot are removed by a hole conductor or redox couple and are transported to a counter electrode. If we can optimize the paint preparation, it should be possible for anyone to open a bottle (or a can in the long run) and apply it to a conducting surface. This will decrease the variability between lab to lab or person to person as one encounters in a multi-step process. Having fewer fabrication steps and ambient preparative conditions should provide an economically viable transformative technology.

During their research the scientists tested a number of different compounds, but found that a composite of mixed CdS/TiO2 and CdSe/TiO2 nanoparticles performed best, particularly when the CdS and CdSe was deposited directly on the TiO2 nanoparticles as a coating.

Significant Uses

Describing their work they said the nanoparticles were suspended in a water-alcohol mixture to create the binder-free paste, which was then applied to a conducting glass surface and annealed at 200 degrees Centigrade. When coated on a glass electrode, the paint has an overall power conversion efficiency exceeding 1 percent. Although some multifilm quantum dot solar cells have efficiencies greater than 5 percent, the scientists believe that using different quantum dots and further optimization could significantly increase the efficiency of the paint.

Potential uses could include painting electronic devices such as cell phones to recharge their batteries, larger electrical devices such as computers, and even whole rooftops, windows, and cars.

The scientists’ work has attracted some major governmental interest and the Department of Energy’s Office of Basic Energy Sciences is funding their research.

Professor Kamat concluded in a Notre Dame press release:

We want to do something transformative, to move beyond current silicon-based solar technology. The best light-to-energy conversion efficiency we’ve reached so far is one percent, which is well behind the usual 10 to 15 percent efficiency of commercial silicon solar cells. But this paint can be made cheaply and in large quantities. If we can improve the efficiency somewhat, we may be able to make a real difference in meeting energy needs in the future. That’s why we’ve christened the new paint, Sun-Believable.

The Importance of Government Subsidies to the Solar Energy Market

By John C.K. Daly of  Oil Price.com 

In any country, at the end of the proverbial day, both energy utilities and consumers are finally interested in the technologies that generate a kilowatt of electricity most inexpensively, all other considerations aside.

Accordingly, all countries involved in solar energy are optimists, but nascent industrial efforts to generate power on a commercial scale from the sun are without exception dependent upon current government subsidies to enter the market, which is littered with optimism, the failure of U.S. federally subsidized company Solyndra being Exhibit A.

But countries worldwide are seeking government support to shield their embryonic solar industries from market realities until conditions improve, and few countries are more caught between the realities of the “free market” and national priorities in developing energy alternatives than Israel, whose energy imports remain a major topic of concern to the government. Subsidies are viewed as critical worldwide by solar producers, especially in a recession market, but fiscal realities are asserting themselves, which alternative energy companies warn could kill their efforts.

Israel’s government is now reconsidering its alternative energy policies due to fiscal constraints, to cut the incentives price for mid-sized photovoltaic power plants.

Association of Renewable Energy of Israel CEO Eitan Parnass bluntly told Public Utilities Authority (Electricity) acting chairman Orit Farkash-Hacohen, “People will avoid private power production in Israel if the rates the entire industry relied on are changed.”

Solar Panel Prices Down

As a consequence of the global recession that began in 2008 prices for photovoltaic solar panels worldwide have receded. Quite aside from substantial economic recessionary pressures, Chinese manufacturers of photovoltaic solar panels are now facing a substantial inventory backlog of unsold panels. Electricity market sources say that several Western countries that are prominent in the solar energy industry, such as Germany, Italy, and Spain, have reduced their subsidies and tariffs to solar energy producers, because of the global crisis.

In Israel however, the steep decline in prices for photovoltaic solar panels initially generated unexpected profits for solar power companies, as national electricity rates were set two years ago, but Israeli solar companies are now threatened by the proposed government reduction in subsidies.

Accordingly, the Public Utilities Authority plenum decision is awaited by Israel’s solar community. In seeking to advance their arguments, solar companies aver that the Public Utilities Authority is not considering their expenses since 2009, when almost no power production licenses were issued, due to bureaucratic delays.

All is not bleak on the Israeli solar front, however – on 24 October SolarEdge Technologies Inc., a firm that developed a power harvesting and monitoring system for photovoltaic panels capable of improving the performance of solar energy systems, raised $37 million in venture capital, primarily from California-based Norwest Venture Partners.

Despite issues of funding of solar panels electrical production, in July Arava Power inaugurated its 4.95-megawatt solar power field. In the future, Arava Power projects launching 40 solar energy fields in the Negev desert region, assisted by tariffs for investors supported and guaranteed by the government.

Role of Government

Interestingly, despite Israel’s renowned high technology base, Arava Power has partnered with Chinese-produced Suntech photovoltaic solar panels because Israel’s nascent solar energy is currently unable to compete. Arava Power CEO Jonathan Cohen CEO said, “The technology needs to be time-proven to prove its bankability. When the means are made available to ensure Israeli novel technologies are included in Israel’s solar drive, we and others will be looking to employ them as much as possible.”

Cohen has reason to be sunny, as on 21 October Israel’s Public Utilities Authority awarded Arava Power the country’s first permanent solar license in the aftermath of Arava Power interconnecting its 4.95 megawatt Ketura sun field to the national grid by the Israel Electric Corporation.

So, Israeli solar power – glass half-empty or half-full? Given Arava Power’s experience, should the troubling issue of government support be resolved, it would seem that the container could soon be overflowing, with the only problem being what happens after twilight.

Just a question of government grants to tide companies over the rough patches.
