Designed for resiliency and acoustic performance, University of Iowa Voxman Music Building features Linetec’s anodize finishing and thermal improvement services
The University of Iowa (UI) School of Music in Iowa City celebrated its 110th anniversary with a new home – Voxman Music Building. Designed for durability, sustainability and the highest acoustic performance, the 190,000-square-foot project features energy-efficient window and curtainwall systems, finished and thermally improved by Linetec.
The $152 million project is targeting LEED® for New Construction Gold certification. Wausau Window and Wall Systems worked closely with glazing contractor Architectural Wall Systems (AWS) to achieve the design intent set by LMN Architects and Neumann Monson Architects. Mortenson Construction served as the construction manager agent for UI.
“We conceived the project as a means of extending the public space inside the building, and we do that with glass,” says LMN partner and project designer, Stephen Van Dyck, AIA, LEED AP. “The window systems play a huge part in creating the visual transparency between the public and the performers, and the connection from within and without of this educational and cultural building.”
Linetec Products Support Project Sustainability Goals
Linetec’s thermal improvement services and anodize finishing are key contributors to the window systems’ energy-efficiency, visual appeal and durability. The anodizing process produces a uniform, hard and protective finish. Linetec’s anodize finishes meet the requirements of the American Architectural Manufacturers Association’s stringent Class I specification standard, AAMA 611-14. The anodized aluminum resists the ravages of time, temperature, corrosion, humidity and warping, for a long product life cycle. Anodized aluminum may be specified with recycled content and is 100 percent recyclable.
In addition to durable finishes and recyclable materials, Linetec helped support the project’s sustainable and LEED goals for thermal comfort and energy performance by providing thermal barriers for Wausau’s window and curtainwall systems. Both Linetec and Wausau also are considered local suppliers, as they are located within a 500-mile radius of the UI campus.
Unique Window Systems Supply Natural Light and Visual Appeal
Wausau’s systems also contribute to recognized benefits of daylight and views, and are a main visual feature of the building. The glass exterior begins beneath the concert hall, wraps around and up to the main entrance and continues over the recital hall, reaching heights of 50 feet.
One of the building’s most unique features is the shingled curtainwall – called the “warped wall” – overlaying the recital hall, in which construction of glass and metal units are layered to create an undulating slope that appears to gently pour from the building’s roof to its base. On the interior, a central atrium funnels natural light into the building.
Large-scale window systems are rare in musical spaces due to the acoustic challenges they can present. By choosing a low-iron glass with a low roller wave and horizontal orientation, acoustic and visual distortion was minimized. Large panes of glass diffuse sound at different rates on the shingled wall, and tall and narrow windows minimize vibration throughout.
Prioritizing Acoustic Isolation and Performance
“The acoustic requirements for this project are of utmost relevance,” emphasizes Chucho Loria, AIA, with Neumann Monson Architects. “Wausau’s team looked at the various conditions in the project. They developed details, during the shop drawing review process, to ensure that their system would meet the design intent of the project. It was apparent in those details that Wausau was taking efforts to make their system interact with the rest of the building.”
“We prefer an integrated, whole building approach – especially with complicated engineered projects,” says Doug Laffin, Wausau’s architectural sales representative serving Iowa. “Our systems may be just one part of that whole, but everything must work together to successfully deliver the architectural vision and critical functionality.”
“Almost all of the job was acoustically sensitive,” says Lee Ebel, AWS project manager. “Wausau produced and had tested units that verified the system would meet the necessary STC ratings at the corresponding frequency.”
Sound Transmission Class (STC) is a single-number rating system for acoustical performance, where a higher number indicates better performance. The Voxman Music Building’s design specified an STC 55, which is suitable for blocking loud noises including musical instruments.
“Almost every room is acoustically isolated,” explains Van Dyck. “This means that instead of the usual one wall, one floor between each room, there are two or three walls and two floors to separate most of the rooms and keep sound from transferring between them. We’re also trying to keep the sound from passing from the outside into the building’s interior. The windows are a big part of that equation.”
Adding glazing mass, increasing air space and improving damping by the addition of a laminated interlayer achieve improvement in acoustical performance. Of course, maintaining an airtight assembly to reduce “flanking” noise is critical, especially at high frequency. All three approaches were used to meet the acoustic requirements of the Voxman Music Building.
“The goal was to have virtually no outside noise in the recital hall,” says Randy Arneson, Wausau’s senior estimator on the project. “There’s 5-inch airspace between the inside and outside glass lites of our curtainwall to decrease sound transmittance. For the majority, we used Viracon’s 1-5/16-inch OptiWhite laminated, insulating, specialty glass.”
In the concert hall, the glass was glazed into the window system’s interior-facing plane with a 3-inch airspace. On the exterior-facing plane, electrochromic SageGlass was installed. Electrochromic (EC) glass darkens or clears when a low-voltage DC current is applied. Wausau incorporated the necessary wiring paths to connect the windows’ EC glass with a user-controlled switch. This enhanced functionality allows the faculty and students to reversibly control the sunlight entering their space and to maintain their outside view without shades or blinds.
“Wausau provided these elegant, tall, thin windows with EC glass. They’re really cool. When the windows are turned ‘on’ and tinted, they produce this really nice, diffused light,” says Van Dyck.
“They’re very narrow – some are only 1 foot wide, but 40 feet tall. The smaller span actually helps with the acoustics. The stiffer it is, the less it wants to vibrate.”
Ensuring Quality, Durability and Sustainability
Beyond acoustic performance, Ebel says, “The curtainwall system went through a rigorous performance mock-up test at a certified laboratory in Miami, Florida. The testing included air, water, dynamic, structural, seismic racking and thermal cycling.”
Ebel adds, “The typical LEED requirements applied to this project.” The window systems’ high performance features contribute to quiet, comfortable spaces that promote concentration and creativity, as well as a whole building approach to energy-efficiency, daylighting and outside views.
AWS installed Wausau’s SuperWall™ curtainwall, custom-engineered fixed and operable windows, and nearly 23,000 square feet of INvision™ 1050i-UW Series unitized curtainwall. Glazing and sealing in a factory-controlled environmental ensures that conditions are maintained to achieve the intended performance required for the project. Shipped one lite wide by one floor tall, the interlocking, pre-assembled units make the system easy to install on the job site. This saves labor, time and associated costs.
The curtainwall and window systems’ installation was finished on time and on budget. “It took a lot of coordination between all parties, and modeling of the curtainwall and structure to ensure that everything would fit correctly in the field once installation started,” Ebel says.
“Aesthetically, the project looks great,” concluded Van Dyck. “But, let’s face it, for this project, it wouldn’t matter how great it looks if doesn’t sound great, too. The window systems are a critical part of that success.”
UI’s new music facility replaces its former location, which was damaged by the 2008 flood. Programming and schematic design began in 2011. In 2014, the new building’s essential structure was completed and the building envelope could begin taking shape.
The Voxman Music Building was substantially completed in July 2016 and welcomed its 450 music students and 60 full-time faculty on Aug. 22, 2016. The grand opening and ribbon-cutting event was held on Oct. 21, 2016. The 324-room space includes classrooms, teaching studios, a library, offices, recital spaces, a rooftop terrace, a 700-seat concert hall and a 200-seat recital hall.
David Gier is the first to serve as the UI School of Music’s director in the Voxman Music Building. The facility’s name honors one of his predecessors, the late clarinetist Himie Voxman who served as the school’s director from 1954-1980. Gier and the School of Music have eagerly awaited their new home.

What happens when you bring together 250,000 people from around the world for six days in Munich, Germany?
- Ideas are exchanged.
- Best practices are shared.
- Deeper levels of understanding are reached.
That was, in a nutshell, BAU 2017, the world’s leading trade fair for architecture, materials and systems with the 2,210 exhibitors from 45 countries. More than 80,000 people had, like us, travelled overseas.
From our vantage point at the Kalwall® exhibit – our first time exhibiting at BAU (German for `construction’) – we could see how much the world beyond the borders of the United States is changing and this was a chance to see how architects, owners, contractors and other business people are responding to those changes.
Here are three key takeaways from BAU 2017 affecting daylighting and fenestration globally.
1. Safety and security is no longer just about airports and government buildings
The safety, security and privacy of guests at hotels, students at schools and employees at banks and high finance institutions are becoming harder to ensure. While airport administrators and government facilities have been working with Kalwall for years to find solutions to similar problems, it was interesting to see the volume of private business owners looking for similar answers.Kalwall’s specialty systems meet UFC 4-010-01 blast requirements and can, for example, provide an extra level of safety for guests in a hotel lobby from a car bombing in the street outside. The translucent panels also afford more privacy while providing museum-quality daylighting™ for interior spaces.
2. Canopies need to be rugged and resistant to pollution
Pollution and heat in certain regions of the world take their toll on canopies meant to provide shelter and shade, leaving architects and construction managers searching for alternatives to less durable polycarbonates.The ruggedness and capacity to resist fading in intense heat, along with its ability keep clean where pollution is a concern made Kalwall canopies an appealing option to business people in desert climates as well as industrial cities.
3. Energy is expensive and daylighting solutions are more important than ever
Technology was a dominant part of the conversation at BAU and a major reason why the world is seeking better ways to produce and store energy. I think my grandfather, Kalwall founder Robert R. Keller, would have been smiling. After all, energy efficiency was one of the reasons he developed his translucent sandwich panel in 1955.
Our technology, with its best in industry thermal and solar heat gain performance, was a conversation starter for business people concerned with the high cost of energy and the ways to be efficient. Renovations, in particular, present cladders the challenge of finding energy efficient solutions.
BAU 2017 was an opportunity to expose more people globally to the benefits of Kalwall. They came looking for the latest advancements, but some technology stands the test of time. This was re-affirmation of a technology we developed 62 years ago.

Carbon-positive cities, biophilia, and data-centric decisions define the next American city that architects can help create
In discussing solar orchards, biophilic cities, and illustrative mapping of everything from water surges to public protests, architects at the 2016 SXSW Eco conference brought the audience a dynamic voice for change. In its fourth year, the sister conference to the larger South by Southwest festival has grown into a three-day convergence of all things driving global change under the umbrella of design, technology, and business. Its basic premise is a forum for ideation and connection across industries. Participants arrive from around the globe, united by aspirations to establish new ways of dealing with health, food, water, climate change, clean air, energy, and development.
“Architects provide a fundamental voice in this conference,” notes SXSW executive producer Morgan Catalina. “We are talking about environmental and social change. It is a realm that architects can shape, change, and influence through design.” In fact, design thinking and problem-solving were a priority in much of the conference discussions. Topics ranged from idea-driven calls to action to explanations of developing software tools. Creative solutions involving cross- and multi-disciplinary teams were billed as the most effective ways to address many of the world’s pressing problems.
Time for a (sustainability) revolution
In his keynote, William McDonough, FAIA, of William McDonough + Partners, called for a revolution as he emphasized the need for carbon-positive cities and work toward climate change reversal. A visionary for more than 40 years, McDonough has been a pioneer in sustainability. He co-created the Cradle to Cradle philosophy, and all his work promotes a complete understanding of material health in the design process coupled with built-in renewable energy and social fairness.
He is currently working on concepts for a Chinese city that can feed and power itself. In Mongolia, McDonough’s “solar orchards” allow industry and agriculture to live in the same place. Solar collectors are elevated six feet, allowing for grazing animals to occupy the same land. “This is beautiful … grasses come back by themselves,” stressed McDonough. His is a call for a new language to deal with carbon that promotes constant improvement and a reevaluation of the current framework from which architects and designers evaluate their impacts on the environment and the future of human health.
Connections to nature
Likewise, Amanda Sturgeon, FAIA, chief executive officer of the International Living Future Institute, noted that architects should change the way they are designing, and recognize that “people are a part of nature, not separate from it.” As part of the workshop on biophilic cities, she presented her research related to biophilic design emphasizing the reconnection of humans and the natural world. Biophilic cities prioritize the integration of green and blue ways throughout urban zones, urban farming initiatives to support food deserts, and integration of wildlife preservation in planning efforts, among others.
“We are talking about environmental and social change. It is a realm that architects can shape, change, and influence through design.” - SXSW executive producer Morgan Catalina
Sturgeon summarized her argument for new design thinking: “Most of architecture is being created with no connection to place, climate, geography, or regional context. With increasing urbanization, and the fact that we spend 90 percent of our time inside, our fundamental connection with nature is disappearing. At the same time, the Paris climate agreement requires that buildings radically reduce their energy use, past the incremental efficiencies that we have been achieving. If we don’t design our buildings to adapt to our climate, we will not get there. I believe this is an urgent issue for the creation of our buildings. Architects must change the way that they design, and we must train our young architects to have the skills and abilities to design in this way.”
Tools to further the profession
Going beyond just understanding a building’s site was part of the inspiration for Perkins+Will associate principal Leigh Christy to develop Hazel, a software tool for optimizing planning for stormwater infiltration, collection, and reuse. Christy sees part of her role as an architect is to engage in larger questions about the future of the environment. “Hazel is a tool for architects and planners,” she said. “The data help analyze cost, identify policy needs, streamline water detention practices, reduce carbon emissions, improve pedestrian thermal comfort, and create new habitats for wildlife.”
Ultimately, the platform provides data fundamental for project site selection. After being awarded a grant from the AIA College of Fellows Latrobe Prize, Hazel was developed collaboratively by the Arid Lands Institute of Woodbury University, Perkins+Will, the Nature Conservancy, and the City of Los Angeles. The design team is still refining Hazel. Christy notes that after presenting Hazel to architects and city planners, the response from the multidisciplinary audience was refreshing. “It was the first time I had someone come up to me and ask if I needed help coding,” she said.
Another software tool called SPEA (Spatial Practice as Evidence and Advocacy) was developed by a landscape architect–led team. “[We] are of course influenced by the architectural designers that we work with,” said McKenna Cole, research associate at SITU Studio. SPEA visualizes complex spatial narratives like the Euromaidan protests in Ukraine, often using three-dimensional renderings.
“Developing accurate 3-D models allows us to understand events spatially, enabling us to establish known protester and police locations that draws from citizen-captured videos,” explained Cole. The usual outlets for dissemination of the data collected and compiled with SPEA are in the courtroom, through specific publication, or in advocacy reports. SPEA received an honorary mention in the Equity + Inclusion category of the Place by Design competition at the conference.
If this most recent SXSW Eco was an illustration of the prominent role architects can play both as visionaries and as team players working to effect change, the conference also clearly demonstrated that opportunities abound and that people value design thinking. As William McDonough noted, “I’m an architect, and an architect’s job … is to change the way we see, then we rearrange the furniture, and then we build.”

The American Institute of Architects (AIA) announce the release of a new feature – developed in collaboration with Autodesk – that will automate the AIA 2030 Commitment data reporting from energy analysis software directly to the Design Data Exchange (DDx). This collaboration has resulted in an open Automated Program Interface (API) to the DDx, available to any energy modeling software vendor, reducing the duplication of effort using the existing process.
The new automated connection will allow the more than 350 AIA 2030 committed firms to report their project and portfolio performance to the DDx directly from Autodesk Insight 360, a technology addition included in Autodesk Revit and Autodesk FormIt 360 Pro subscriptions. This automated process between Insight 360 and DDx will eliminate the need for manual data entry and eliminates duplication of effort encouraging performance analysis and more frequent reporting throughout the design process instead of annually. The DDx interface is open source with the ability to connect with other energy modeling software providers. Additional vendors are welcome to link up with the DDx system.
Eliminating the overhead of manual reporting not only saves time but it also enables more regular updates so firms can get up-to-the-minute progress on their projects and portfolio. In terms of actually meeting the targets themselves one of the key findings of the 2014 progress report was the critical role that energy modeling plays, and how projects that applied energy modeling were generally higher performing.
For example, of the projects submitted in the 2014 reporting period, nearly 50 percent of the projects where an energy model was created met or came close to achieving the AIA 2030 Commitment goals, whereas 80 percent of non-model projects fell below the 40 percent target. This offering helps to lower the barriers to energy modeling, making it possible to conduct energy modeling on virtually every project, especially from the early stages, but in doing so automatic reporting to DDx is essentially free.

Perhaps no one is more grateful for the $12.8-billion investment to upgrade Ontario’s Darlington Nuclear Generating station than Justin Parrington.
“Without the refurbishment, I wouldn’t have a job,” said the young marketing sales executive at Burlington’s MarShield, during a roundtable discussion about the nuclear project last Friday.
MarShield makes protective gear for people who work in the nuclear industry from medicine to energy production. It is one of several local companies, and among 60 in the province, to reap the economic benefits of the provincial investment to upgrade the aging power plant.
Plenty of the specialty components, supplies, engineering expertise and research needed for the eight to 10-year long project are provided by local firms such as GE Power, Laker Energy Products, Platecon Projects, Stern Laboratories, Clean Harbours Canada and CTSNA Commissioning & Technical Services.
“The number of companies that will prosper from it are tremendous,” said Keith Hoey, president and CEO of the Burlington Chamber of Commerce. The chamber, as well as its provincial counterpart, gathered some of those local vendors together last week to speak with local politicians and the people behind the massive project.
Like Parrington at MarShield, Laker Energy is already experiencing an uptick from the upgrade.
The local company has grown from 20 to 60 staff, thanks to Darlington, said company president Chris Hughes.
“These are high-quality engineering jobs, and we will be up to 75 staff in the next 15 years,” he predicted.
But, as happy as Mark Zimny, president and CEO of Promation Nuclear, is for young people like Parrington who are finding work thanks to the Darlington investment, he’s concerned about the future, especially as Ontario competes with firms in Russia and France, for business in the nuclear sector.
“How will I retain my engineers without new deals to grow the sectors,” he asked. “What’s the long-term plan?”
Eleanor McMahon, MPP for Burlington says the province’s investment in refurbishing Darlington “shows nuclear energy is back in the game.”
She assured Zimny that the province is helping generate a skilled workforce for the industry through its educational policies. McMahon said the post-secondary graduation rate in Ontario is now at 85 per cent and the promise of free post-secondary education to families earning less than $50,000 will eliminate financial barriers for students.
As well as boosting the local economy and labour force, Burlington MP Karina Gould said the investment in nuclear power, of which Darlington supplies 20 per cent for the province’s energy needs, is a low carbon option that is better and cleaner for the environment.
Indeed Roy Martin, who has spent five years preparing for the refurbishment of Darlington as the project director for Ontario Power Generation, said that 97 per cent of the electricity generated by nuclear power is smog free and greenhouse gas free, and costs half as much to produce as other power generators in the province.
“Rebuilding the reactor will give us 30, to 40, to 50 more years of clean, low-cost power generation,” said Martin.

As we reported in our earlier blog post, The Rise of Outdoor Lighting, homeowners continue to place a high priority on renovating outdoor living spaces. Taking center stage in these renovations is outdoor lighting. The report says, “Outdoor lighting is the most common [system] upgrade, whether it is LED (28%), solar (23%) or other (17%).”
The emergence of LED lighting has been a game-changer in outdoor design. Unlike their conventional counterparts, LEDs do not have a filament that will burn out or break, and they have a significantly longer lifespan (50,000 hours or more, compared to 15,000 to 35,000 hours for conventional HID lighting ) – which make them extremely energy efficient.
Because LEDs are so durable and energy efficient, they’ve become the leader in outdoor lighting. They can be used anywhere on your property, from lighting walkways and steps to illuminating patios and outdoor living spaces. Here are a few ways high efficiency LEDs are playing a significant role in outdoor lighting design.
Lighting the Way – In outdoor landscaping design, lighting can be a visual cue for defining the entrance to a home. It can be as simple as additional walkway lighting to as multifaceted as using many options to create a dramatic illuminated pathway to the front door.
Marking the Perimeter – If you have a deck, LED rail lighting can offer a modest amount of light that can set the ambiance for an evening gathering while still marking the deck’s perimeter. Also, LED rope lighting is often used to outline raised flower beds and water features.
Adding a Layer of Safety – Once the sun sets, outdoor areas can be a bit more dangerous to navigate; however, LED lighting as a design element will add a layer of safety to steps. Lighting is often added to hardscape stairs, or as seen below with the LED Post Accent Light . In this scenario, the accent light attaches to the post face to create a warm, white light.
Putting Functionality into Outdoor Kitchens – To add more functionality to outdoor kitchens, LED flexible strips are being integrated into outdoor bar and cooking areas. These strips position nicely under cabinets or along the underside of countertops and provide the perfect accent lighting, as well as make the outdoor kitchen much more functional after dark.
Accenting Landscaping Elements – One of the key benefits of using LEDs in landscape design is that they can be positioned to emit light in specific directions. Up-lighting under trees, for instance, creates interesting shadows, sometimes referred to the “Frankenstein Effect.” Alternately, strategic positioning of up-lights allows them to illuminate an architectural detail of the home, or even a piece of outdoor artwork or sculpture.
As LEDs continue to extend their foothold into landscape design, so will technological advances – bringing with it creativity and inspiring ideas for all to enjoy.

Many electrical hazards exist in a workplace where workers are performing electrical-related tasks. One of those hazards is an arc flash.
An arc flash, as defined by the Workplace Safety Awareness Council is “a phenomenon where a flashover of electric current leaves its intended path and travels through the air from one conductor to another, or to ground.” A person located near an arc flash can be seriously injured or killed.
An arc flash can be caused by a variety of things, such as dust, dropping tools, accidental touching, condensation, material failure, corrosion, and faulty installation.
To protect workers, the National Fire Protection Association (NFPA) developed approach boundaries to be used by workers on or near energized equipment. They include:
Limited Approach Boundary: The minimum distance from an energized source where an unqualified person can stand. A qualified person who can enter that space is wearing proper PPE and been properly trained.
Restricted Approach Boundary: A shock protection boundary that can only be crossed by a qualified person who has been properly trained and is wearing proper PPE.
Prohibited Approach Boundary: A shock protection boundary that can only be crossed by a qualified person wearing PPE and been trained to work on energized conductors or components. Workers also must have a documented plan to perform the work before crossing this boundary.
Arc Flash Boundary: A safe approach distance from energized equipment or parts.
Some general ways in which you can protect workers from electrical hazards on the job are:
- De-energize the circuit
- Work practices
- Ground Fault Interrupters (GFCI)
- Grounding (secondary protection)

Watch this 14-day time lapse video which shows how Icynene spray foam insulation does not absorb water compared to other spray foams. Icynene spray foam insulation won't absorb or retain moisture like others. Icynene maintains an air seal even after seasonal building contractions.
Ever wondered how efficient your home really is? The U.S. Department of Energy has created a comprehensive and educational infographic that breaks down what a home energy audit is, what’s involved and how the results can help you and your clients determine the best investments to improve the home’s energy efficiency.
For instance, spray foam can be a wise investment to curb air leakage since the average home has enough gaps that add up to the size of a basketball. These gaps allows air leakage to occur. Check out the infographic below and then discover how spray foam insulation can help play a role in addressing common problems relating to interior comfort and air leakage.
When it comes to energy efficiency in the U.S., many people point to automotive carbon dioxide emissions as ground zero. It's a fair point – according to the EPA, between 1990 and 2012, the transportation sector accounted for 32 percent of all carbon emissions in the U.S. But in the realm of overall energy consumption, another industry is even higher.
The buildings sector – both residential and commercial – made up 41 percent of energy consumption in 2010, according to data from the Department of Energy. Those energy sources consist of coal, natural gas, petroleum, nuclear and renewables. Regardless of the source, building owners would be better served if they could conserve as much energy as possible without sacrificing comfort or aesthetics.
As it turns out, there are reliable, modern techniques that materials architects can rely upon to help reduce the amount of energy consumed by the buildings industry in the U.S. New buildings outfitted with air and moisture barrier systems and continuous insulation wall systems help maintain a comfortable interior by preventing unwanted airflow and heat transfer.
For builders, zero is the magic number
Net-zero homes – those that produce at least as much electricity as they use – are nothing new. However, only recently have they emerged as something other than a custom home for the supremely wealthy, reported The Wall Street Journal. That prior perception is not unwarranted, as net-zero homes often are expensive to build. But a few architects have made a push to bring the net-zero building to the mainstream.
These pioneers are driven by increasing demand, both from individual consumers and by way of increasing regulations regarding building emissions. With that said, the market is not yet to the point where every home and business owner is clamoring for a net-zero project. But some of that could be influenced simply by letting consumers know what is available.
Net-zero price point on the decline
As it stands, a net-zero house is still out of the price range for many. But where it was once the solely available to multi-millionaires, developers are working on homes that would appeal to upper-middle income families. Blue Heron Design/Build LLC told The Wall Street Journal it could build net-zero homes at a cost of around $700,000 – not low-income housing, but certainly more affordable than the designer homes that net-zero had become associated with.
"Net-zero is technologically and financially solved," C.R. Herro, vice president of environmental affairs at Meritage, explained to the WSJ. "It's now a matter of the consumer catching up to that potential. That's probably another three years."
In addition, the cost of energy-efficient systems has fallen in recent years as technology and installation methods improve. For example, solar-power systems' average installation cost has declined by 50 percent since 2010. Exterior wall insulation and similar systems provide financial benefits that help offset the initial cost.
While zero is difficult to achieve, many builders that seek energy neutrality will, at the very least, greatly reduce energy consumption. Last year, the Department of Energy certified a mere 370 homes as net-zero. But another 14,500 fell just short of net-zero specifications. For now, even the attempt at net-zero will yield significant energy savings.
