In today’s world, when a group of people in a community set out to create a new building, or improve an existing one, the crucial question each of must ask ourselves and each other is  - “In 10 years, 20 years, 50 years will this building be part of the solution, or will be part of the problem?”

Every decision we make when we’re designing and building sends a message to our community, the next generation and to the world at large about our respect for ourselves, each other, and the environment in which we live in and rely on. Many efforts deemed as “good enough” today will inevitably reveal themselves to be woefully inadequate in a not too distant future where escalating energy prices reflect the true cost of our dwindling precious resources. These decisions are an enormous responsibility and require a shift in thinking from short term fixes to long term planning.

Essentially have two choices. We can design, build and retrofit with the idea that we will always have fossil fuels and saddle our families and communities with liabilities. Or, we can design, build and retrofit to address the fact that the emerging economy is one that must be based on energy conservation practices and products and sustainable sources of energy. Choosing to do the latter leaves our families and communities a legacy of assets that will actually benefit instead of burden them. I, for one, am not thrilled about the idea of my hard-earned retirement savings being gobbled up in energy costs associated with poorly planned and poorly built buildings, nor for that matter, poorly sealed oil wells.

After almost 3 continuous months (85 days) and 4.9 million barrels of leaked oil, with the assistance of Halliburton, BP finally plugged the oil well gushing into in the Gulf of Mexico on July 15th. Bloomberg Newsweek reported on August 9th that according to BP, the cost of stopping and cleaning up the oil spill had risen to $6.1 billion. BP has set aside $32.2 billion and is selling its assets to pay for the world’s largest offshore accidental oil spill.

I found myself wondering, in addition to all the money, human, animal and plant life being sacrificed to maintain this addiction to fossil fuels, just how much usable energy was wasted by this spill?

There are 5.8 million BTU’s or 1700 kWh per barrel of crude oil. But we can’t count all of the energy contained in crude oil, since fossil fuels have to be combusted to release the energy contained within them. Also, because we don’t actually use oil as a feedstock for power plants, we have to look to fuel oil, coal and natural gas to get a sense of relative combustion efficiencies. Excluding transmission losses, the average efficiency of coal-fired power plants is 31%, while natural gas-fired power plants have an efficiency of around 58%. Using a conservative efficiency rate of 30% to look at the actual “usable” energy contained in the spilled oil:

4.9 million barrels crude spilled =

2.5 billion usable kWh wasted (at 30% combustion efficiency assumption) =

The energy needed to power 89,756 average US homes for a year

As of the 2008 census, there were about 130 million housing units in the US. The majority of them leak. The energy lost through inefficient single and dual pane windows alone can be up to 40 percent of a building’s heating and cooling energy. According to the DOE, this energy loss is costing consumers approximately $35 billion per year. They leak energy, greenhouse gas emissions, and money. So how does the energy wasted by our homes every year compare to the more visible catastrophe of the BP oil spill?  According to the EIA’s most up to date Residential Energy Consumption figures, in 2008 an average US home used 27,842 kWh.

We can all agree that at least 15% of that 27,842 kWh is wasted energy. Now, if we were to do some thoughtful planning and retrofitting, 30% - 50% of that average energy consumption could be eliminated. If we do deep energy retrofits, and build to standards such as Passivhaus (Passive House), we can eliminate 80% of that energy consumption – and save money, month after month.

Take the Empire State Building as an example. It is currently undergoing a retrofit that will reduce energy use by 38% and save $4.4 million in energy costs every year. The retrofit, including the window upgrade of all its dual pane windows, will pay for itself in 3 years. And so goes the saying: if we can do it in the Empire State Building (an 80+ year old iconic tower), we can do it anywhere.

Zero energy buildings will be and must be our future. If we can build and retrofit buildings TODAY that use 20% of the energy that typical buildings use, then I consider the other 80% of the total energy a typical US home uses as “wasted”. That energy is not only a burden on our ecosystems, but also a burden on our power distribution grids. From that perspective, here’s a breakdown of the energy we are wasting with our leaky, poorly insulated houses:

Energy Wasted/Year by US Homes = 1,150 BP Oil spills
Energy Wasted /Day by US Homes = 3 BP Oil Spills

Astounding! To date, the BP Oil Spill is the world’s largest offshore accidental spill, but it is dwarfed by the amount of fossil fuels we are wasting to power our buildings every day! This in my opinion is the real call to action! The good news is that cost-effective methodologies and technologies available NOW can turn this around to the point where our buildings are so efficient that they can power our cars with the extra energy they produce, and we can be done with this dead-end petroleum addiction. And save us real money while we are at it. This blog series aim to offer some straight talk on energy and building science and provide some tools and inspiring ideas to “Build it Forward”!

For optimum energy efficiency, air tightness of your whole home (building envelope) is critical - as Blake the Builder of Bilyeu Homes explains. See how an Oregon Passive House certified home is tested for air infiltration, as part of the Passive House design standard, and the remarkable results it accomplishes, in this video. The house averages 0.26 ACH50 on the critical blower door test for Passive House, a remarkably tight number. Using a variety of energy efficient approaches and materials, including super-insulating high R-value and tuned SeriousWindows, this traditional style home accomplishes 90% energy reduction compared to the typical homes we live in today. Blake is proving that energy efficiency, near net zero, IS possible - with the right building and design mix. In Blake’s own words, “eat your conservation vegetables before your solar cookies”! Focus on reducing your energy demands - first. Here’s to that!

Watch DIYNetwork’s Amy Matthews visit to Serious Materials’ Colorado window factory to find out why you lose so much energy from dual pane windows. You’ll get an inside look at how high R-value super-insulating windows are made in one of our plants. It was terrific to host Amy and the crew from their great new show This New House! You can still catch the entire episode on the DIYNetwork - check dates and times here.

Blake Bilyeu of Bilyeu Homes, Inc. recently completed this new home construction in Salem, Oregon. The home may look generally ‘typical’, but it happens to be one of the most energy efficient, air tight in the country. In this video, Blake explains the wishes of the home owner - to have a low energy house - without knowing exactly how to achieve it. While the owners originally thought “let’s go solar”, Blake educated them on the Passive House standard, and went to work. Passive House design is based on super-insulation, an air-tight envelope, tailored and tuned window placement and glass package according to the building’s orientation towards the sun, and internal heat from its residents to maintain air temperature. The result is a home that uses 90% less energy. Amongst other energy efficiency measures (that you learn about in future posts), Blake specified super-insulating fiberglass framed SeriousWindows, working with Medallion Industries, with a full frame high R-value of R-7 and an AAMA air infiltration rating of less than 1. Check out the owner’s blog documenting the process (and end result).

Study Offers Solid Data for Cost-Effective Residential Retrofits and New Construction (full press release below)

SUNNYVALE, Calif. – August 3,  2010 –  Serious Materials, the leading provider of high-tech products and services which reduce energy usage in the built environment, today announced that a recently completed study ranks high R-value windows as the number one consideration for optimum energy-saving performance and return on investment for both residential retrofits and new home construction.

The study, completed by Ann V. Edminster, M. Arch., LEED AP+ Homes, a nationally recognized expert on green home design and construction, reviews popular energy improvement options in two different residential retrofit scenarios in three climate zones, and seven energy variables in new home construction. The study helps remodeling businesses, homeowners, architects, builders, and energy professionals identify the most cost-effective means of improving home energy performance. The analysis was performed as research for her latest book, Energy Free: Homes for a Small Planet.

In one scenario, Edminster asks (and answers) the retrofit question: “If I have $15,000 to spend on my home to reduce energy use as much as possible, what gives the best bang for the buck?” She then weighs and compares the performance of three popular energy retrofit approaches when applied to a typical 1,900 square-foot suburban home, which are:

•    Energy Improvement Package – includes increasing insulation (to R-49 in the attic and R-13 under flooring), sealing all air leaks throughout the home (weatherstripping, caulking, etc.) and upgrading lighting and appliances to ENERGY STAR® compliant models.

•    Replacement Windows – replacing both R-1 (single pane) or R-2 (dual pane) with full-frame R-5 windows.

•    Photovoltaic Solar System – 2kW array installed on roof.

Note: Full-frame R-value (the inverse of U-value) is a measure of thermal resistance used to compare insulating values through any partition. The higher the R-value of a material, the better the insulating properties. An average insulated wall is approximately R-13, while ENERGY STAR® rated windows are only approximately R-2 to R-3 (varies according to climate zone). A higher R-value defines which window will better retain heat on cold days or cooling in hot weather.

The study results clearly indicate that high R-value replacement widows are not only competitive with other retrofit alternatives, but in various situations they were also the clear number one choice performance-wise.

In the single pane (R-1) window replacement scenario, the R-5 window upgrade yielded a dramatic 38.4 percent improvement (with a 1.05 KBtu/sf-year energy reduction for every $1,000 spent) – more than three times the value of the Energy Improvement Package, which yielded only a 12.4 percent reduction in energy use. The Solar System provided the least energy benefits, with only a 12.1 percent reduction in source energy and 0.33 KBtu/sf-year per $1,000 spent.

While values and savings were closer in the dual pane (R-2) window replacement scenario, the study still clearly demonstrates that R-5 windows are competitive with other retrofit alternatives. Also in this study, when viewing new home construction energy features, high R-value of windows provided the greatest influence on whole-building energy-efficiency.

“R-5 and above windows represent a game-changing entry into the residential replacement window market and into the broader realm of energy efficiency retrofit options,” notes study author, Ann Edminster. “While in the past, window replacement was not typically viewed as offering a good return on investment from an energy perspective, it should now be considered routinely for home energy retrofit projects, with comfort improvements the icing on the cake.”

In every case, both for this study and on all retrofit and new construction installations, numerous variables come into play that must also be taken into consideration to maximize a home’s energy efficiency performance – such as orientation (which way windows face), window technologies and overall window area.

“While this analysis does not address every climate, design or other circumstance, it provides ample evidence that our high R-value windows (R-5 to R-11 full-frame) are critical to energy savings and they offer extremely good value and fast payback compared to other techniques,” adds Serious Materials CEO and President, Kevin Surace. “Both in new homes and existing homes where energy performance is a priority, ultra-advanced windows, such as those from Serious, are a top consideration.”

Doug Boleyn is an energy expert. In 1974, he and his wife built a solar heated home. Today, Doug manages commercial solar programs for Energy Trust of Oregon, sits on the Board of Directors of Solar Oregon, and has applied his energy conservation expertise to countless projects. Doug leads through practice, demonstrating Net Zero design in his current Pacific Northwest home. We met Doug and the partners on his Net Zero home project, energy efficiency builders Cellar Ridge Custom Homes and architect Mathhew O. Daby a couple months ago during Solar Oregon’s Goal Net Zero 2010 event.

A key strategy Doug implemented is the practice of “directionally tuning” high performance glass to manage the sun to his home’s energy-saving advantage - allowing for greater overall efficiency, cost-savings, and indoor comfort. Critical to the art of tuning is understanding your climate and orientation of your home relative to the sun. In Doug’s case, the Pacific Northwest is a mild climate - one of few extremes.Window performance is critical to capture as much solar energy, “free heat”, as possible, for best energy-saving winter performance, extensive views and daylighting, and air ventilation and cooling during warmer days. Doug explains the concept in this short video:

Understand Doug’s energy-saving strategies in this paper (PDF download) about his “Morning Sun: A ‘Net Zero’ Energy Home” - an absolute must read case study that combines energy conservation with maximum ‘harvesting’ of energy. An excerpt of the paper introduces his “tuned” approach:

43 percent of the window area faces south, providing unobstructed direct sunlight in winter, yet with carefully designed overhangs to prevent summer overheating. Serious Materials-brand windows were selected because they provided very low U-values coupled with variable Solar Heat Gain Coefficients (SHGC) that were suitable for the different facades on the house.

See pictures of Doug’s house here.

Thomas McGrath is very serious about reducing energy usage of the 1890’s building he owns in Chicago. With partners Ted Roszkowski of ACT Construction and architect Gerhard Zenserling, this “gut retrofit”,  resuses as much existing materials as possible and focuses on replacing energy inefficient materials where needed - like the windows. The net result aims to be USGBC Leed Platinum, Chicago 3 star rated, and Energy Net Positive (meaning, excess energy will power the building, going beyond just being energy “net zero”).

Thomas is documenting the entire project on his blog. His latest update emphasizes the use of high R-value fiberglass windows - a key contributor to one of the core elements of his energy saving retrofit, “super-insulating”. Thomas explains…

…an average window might have an R value of 1.  A really well-made double pane window from a company such as Marvin or Pella might achieve an R value of 3.  The Serious Materials Windows achieve an R value of 9.  The higher the R-value-the higher the resistance, the higher the resistance the higher insulation, the higher the insulation- the slower heat moves through the material, and the slower heat moves through- the lower the energy required to heat or cool the inside space.

From his great pictures, you can tell that the building incorporate more window area in the design than what one may usually see (higher window-to-wall ratio). With his SeriousWindows, Thomas is able to accomplish super-insulation, reduce heat loss, and manage solar heat gain to his advantage - all contributing to the overall building energy saving performance and indoor comfort (of the future lucky owners!).

There are many things that make this project extraordinary, amongst them, Thomas’ first step of the project - transforming the garage into the power-house for the retrofit work currently underway.  The photovoltaic (PV) array, the garage provides power to the workers - for lighting the construction project, powering up tools, heating the space, etc. All the energy required to reconstruct the building is being generated onsite. That’s a very serious approach to how to rebuild.

For those of you attending GreenBuild in November, in the great city of Chicago, don’t miss your opportunity to experience this inspiring retrofit for yourself - the project will be part of the GreenBuild Tour Program. We look forward to seeing you there, and Thomas and Team, congratulations!

Liane Curtis recently finished installing high R-value fiberglass windows into her home in Somerville, Massachusetts. The install was part of a Deep Energy Retrofit project Liane is currently undertaking. This project, incorporating SeriousWindows and other energy saving measures, will decrease her home’s energy usage to less than half of what it used to be! She has put together a great blog detailing every step of the retrofit, including the install of and reaction to her new windows. Check out her blog here to learn more about her project.

Thank you for doing a great job documenting and sharing your work - it’s exactly the kind of education and inspiration to save money, save energy, and build a better future that the world needs to see!

Architects Thompson Naylor and Hartman Baldwin are working with Allen Associates to design and build an exemplar energy efficient, sustainable community in the heart of downtown Santa Barbara, CA, built on an infill site.

They are certainly doing a lot to pull that off. All of the community’s electricity is generated through passive solar design and Photovoltaic panels, which heats hot water using solar thermal units. All lumber used in construction originated from sustainably harvested forests (FSC certified), and all concrete was mixed using a 50% fly ash mix. The development is also completely free of fossil fuels (except minor use in a backup heating system), and 100% of rainwater is retained and recycled on site.

An important design criteria for this sustainable community development was high acoustic performance. Why does sustainability require quiet? Because noise is the main reason people refuse to live in denser urban environments. No one likes hearing the neighbors and having one’s own privacy restricted. But, there’s no doubt that sustainable community living saves energy. A person’s carbon footprint can be reduced by 50% or more by moving into urban downtown centers like Victoria Gardens.

Noise reducing, “soundproofing”, building products specifically transform noisy, undesirable areas, not only in downtown areas, but also along highway and airport corridors, into comfortable, high quality living environments. Allen Associates used QuietRock soundproofing wall solutions for high noise reduction. QuietRock 525 is used throughout the development for reliable noise control.

The Victorian-styled centerpiece home of the development use fiberglass-framed, high full-frame R-value SeriousWindows 725 series throughout. The SeriousWindows fiberglass-framed systems contribute to the sustainable architecture - the inherent advantages of fiberglass (compared to aluminum or vinyl) include enhanced lifetime durability, higher thermal performance, and a lower embodied energy footprint.

The project has been registered for LEED® certification and expects to receive the level of Platinum (the highest possible). The Victorian centerpiece was completed just last year, and the three condominium residences are scheduled to be completed by early 2011.

CW-Rated SeriousWindows™ feature highest thermal (up to R7) and structural ratings available

Sunnyvale, CA – June 9, 2010 – Serious Materials announced today it has launched a new line of extreme-energy-saving window products for the commercial building market. Heavy Commercial SeriousWindows Series are the first heavy commercial (CW) rated windows to deliver thermal performance of up to R-value 7.0 (U-value 0.14), over two times the thermal insulation of commonly specified aluminum thermally broken commercial windows (U-value 0.35). Incorporating SeriousGlass™ super-insulating glass units with fiberglass frames, Heavy Commercial SeriousWindows Series offer architects, builders, and building owners the next generation in energy efficient commercial window systems for substantial energy cost savings. Serious Materials will introduce Heavy Commercial SeriousWindows during the American Institute of Architects Convention and Expo, June 10-12, 2010 in Miami, FL.

Heavy Commercial SeriousWindows enable energy-efficient window strategies including passive heating and cooling coupled with maximum daylighting to significantly reduce energy load and greatly improve the environment for building occupants. In addition, the inherent advantages of fiberglass over aluminum framing systems include enhanced lifetime durability, higher thermal performance, and a lower embodied energy footprint.

“With today’s higher industry standards for thermal efficiency, it’s absolutely critical we enable our customers to build and rebuild with energy performance and savings as a top priority”, said Ian Sullivan, General Manager, Windows & Glass Division of Serious Materials. “Not only does this system exceed anything else in the market by 38% in thermal performance, but also a CW100 rating with outstanding air and water numbers puts this product in a class of its own.”

Thermal Performance

Available in full-frame high R-values up to R-7.0, this new SeriousWindows Series is ideal for commercial new construction and retrofit particularly in extreme heating- or cooling- dominated climates where high R-value glass is needed. With a full range of low and high solar heat gain glass packages, SeriousWindows enable solar control according to climate zone and orientation for maximum energy efficiency and comfort benefits.

Superior Air and Water Tightness, Structural Ratings

With proprietary fused corner joints, Heavy Commercial SeriousWindows feature industry leading air and water infiltration rates. SeriousWindows are AAMA Gold rated with industry-leading air infiltration of less than 0.01 and water penetration (15 psf).

The Fiberglass Advantage

Fiberglass-framed commercial windows offer significant advantages compared to traditional aluminum, vinyl, or wood framing materials – offering super-insulating and structural performance, lower embodied energy, and new design choice. According to the American Composites Manufacturers Association (ACMA) Pultrusion Industry Council and the American Architectural Manufacturers Association (AAMA) Fiberglass Material Council:

• Fiberglass’ thermal conductivity is 800 times less than aluminum, making it the optimum material for super-insulating windows and preserving overall performance for the life of a window.
• Low thermal expansion maintains the windows’ structural integrity and minimizes warping or leakage, making fiberglass the most durable framing material that will not compromise the performance of the full window over time.
• Fiberglass particularly resists environmental damage caused by corrosive salt air or high temperatures.
• Comparing U-value of materials, fiberglass offers 89% better insulation than aluminum (fiberglass U-value is 0.2 – 0.3 compared to aluminum thermally broken of U-value 1.0).
• Superior strength to weight ratios making Heavy Commercial SeriousWindows ideal for large window openings - 86% of the yield strength of aluminum and, pound-for-pound’s, stronger than aluminum in the lengthwise direction.
• Pultruded fiberglass distributes impact load to prevent surface damage even in sub-zero temperatures.

The Anti-Triple Pane Window

Whereas other commercial windows use three panes of glass to achieve higher insulation performance, SeriousGlass units incorporate suspended film systems that create multiple chambers for high thermal performance. Heavy Commercial SeriousWindows are available in either dual chamber (one film layer) or triple chamber (two film layers) SeriousGlass packages. Beyond super-insulating performance, these SeriousGlass systems achieve high light transmission and 99+% UV blockage through the combination of multiple chambers and low-e coating glass surfaces. Up to 50% lighter than triple-pane windows, SeriousWindows eliminate the weight issues of the older triple-pane design approach. Proven in thousands of commercial and residential projects over nearly 30 years, SeriousGlass has been consistently certified at the Insulating Glass Certification Council’s “A” level over more than two decades, and has been installed in extreme climates and high humidity commercial and residential applications.
