Let’s reiterate what creating quieter rooms has to do with saving energy and “green building”. There are a few reasons quiet and sustainability go hand-in-hand:

• In this homeowner’s case, using one 5/8 inch piece of drywall is equivalent (acoustically) to using 6 sheets of regular gypsum drywall. The third largest greenhouse gas producer in building materials is the manufacturing of gypsum drywall, a process that was invented more than 100 years ago. The ability to do more with less means less materials, less waste, less energy, and less embodied energy of your home. You can also gain floorspace in your projects with QuietRock compared to older soundproofing methods.
• One of the best moves a person can make to have a major impact on the environment is to live in urban settings or denser communities - to cut down on our daily, personal carbon footprints. If everyone in the US lived in this way, we could cut carbon emissions by 1B metric tons or more. That is about what Italy and the UK generate as a whole combined. But today, the number one reason why people continue to aspire to the cul-de-sac and white picket fence suburban living is because of NOISE. We can build to take this concern off the table, and save energy, save money, and enjoy quiet, sustainable spaces.

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”!

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.”

THX decided that it was “a natural extension of their program” to not only provide people with the best quality sound, but also to give them a quality room to keep that sound in. So, like with audio and video, they went through different soundproofing products, and we are honored that they chose QuietRock as their certified drywall. QuietRock is the soundproofing material of choice for the stringent noise damping requirements of Universal Studios - as well as healthcare, education, and government buildings, and many others.

When asked about why THX chose QuietRock, Andrew Poulain (THX Director of Sales) said:

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 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!
