The Joy Of Silence
S
ilence is an amazing thing. I first experienced it during a trip to Zion National Park several years ago. I was in the canyon much before sunrise to photograph the light as it lit up the rock formations. Photographing at sunrise is kind of a hurry-up-and-wait adventure. You
force yourself out of bed, hurry to get to your location while it’s still dark, and set up your gear. Once you have the gear set up, you can relax and wait for that first light of the day. It was at that point that everything stopped for me. Silence hit me like a ton of bricks. I was in the middle of this massive, impressive creation of nature and there was no sound. No cars. No people. No appliance motors. No HVAC air. No phones. No e-mail notifications. Just dead, still, silence. I found a rock, sat down, and soaked it up like a sponge. I had the same experience during a recent trip to the Arizona desert. I hiked to my location in the dark, using a flashlight to avoid cactus spines. This time I knew I was about to be enveloped in silence, so I hurried to set up the gear, then stopped to enjoy the complete relaxation and head clearing that happen when there is no ambient noise. It wasn’t long before the first bird chirped, light appeared over the horizon, and the desert came to life. As I was making images that morning, I started to connect the silence I’d experienced with why I like to get up early in the morning to enjoy a brief period of quiet and clear thought before the day starts. That led me to contemplate our lead feature about acoustics in schools and the impact sound has on young ears (p. 8). No matter your age, it takes a lot of energy to filter out ambient noise and distractions so you can focus on the job at hand, and that applies to everyone, including children with their young ears. One of the surprises for me when I read the story is that those young ears don’t necessarily hear as well as we think. I’m encouraged that there is a concerted effort these days to address acoustics when designing commercial spaces. While the desire for green certification is helping push acoustics to the top of the list, there are a boatload of schools in the country that were built with no regard for acoustics. I once taught in one of those schools and experienced first hand how difficult it was for the students. And, yes, I found myself talking louder than normal to compensate. Acoustics aren’t limited to schools. We addressed acoustics in healthcare settings in our Jan/Feb

2014 feature and in a Commercial Conversation podcast with acoustics expert Gary Madaras. The overriding message in all three offerings is that controlling acoustics is critical if you want the occupants to have a positive experience. The good news is that achieving optimal acoustics is getting easier as we better understand the impact sound has on people and as manufacturers develop products that are designed to help achieve better sound control in space designs. We can’t eliminate ambient sound in buildings and, in many cases, probably don’t want to. So even if I’m not able to experience the relaxing total silence I experienced in the Arizona desert, the next school, medical facility, or workplace I visit promises to be a little more peaceful and a little less acoustically tiresome. It may not be perfect, but it’s a start. CBP

due to high levels of noise. It is well understood that a speaker naturally increases the level of their voice in the presence of increased ambient noise levels; this is called the Lombard Effect. Recently, it has been reported that teachers in highly reverberant environments report lower job satisfaction, reduced energy, and increased interest in leaving their job,” Gustafson said. LACK OF AWARENESS?
Industry insiders are divided about why so many classrooms have poor acoustics. Were designers simply not aware of acoustical issues or was it a lack of funds that resulted in classrooms that limited the learning capacity of students simply because of poor acoustics? Browne doesn’t think it’s a lack of awareness. “Acoustics in the classroom are pushed heavily in the industry. All of the material manufacturers push this message as does the Acoustical Society of America, American Speech-Language-Hearing Association, and the U.S. Access Board. There is an ANSI standard that focuses on classroom acoustics, and there are LEED points available for acoustics in classrooms. There are many older buildings that were constructed when different standards were in place. As they outlive their utility and new modern buildings go up in their place, I believe current classroom acoustics standards will be utilized,” he said. Scott Riedel, president, Scott R. Riedel & Associates Ltd., an acoustics consultant based in Milwaukee, disagrees: “Most often it seems that a poor acoustic learning environment is caused by a lack of awareness. Acoustic factors are difficult to remember or imagine in a design planning stage; such factors are not always visibly apparent at the drafting board or screen. An out-of-sight-out-of-mind approach often is the reality during design.” As far as cost is concerned, “while acoustic design service may have a cost, acoustic design implementation can be quite inexpensive,” Riedel said. “For example, a classroom must have a ceiling. Whether that ceiling is made of sound reflective, sound absorbing, or sound diffusing materials, the cost difference might be modest, but the difference in acoustic results can be vast. The cost, measured in poor educational results, from a poorly designed educational space, can be far greater than the cost, measured in dollars, for either a design service or materials selection.” The age of school buildings and, consequently, the prevailing standards when they were built, is another explanation for the poor acoustical performance of some classrooms. “The average age of school buildings in the U.S. is 42 years. Almost half of our existing school buildings were built hurriedly between 1950 and 1969, when the Baby Boomer population surge hit our nation’s education system,” said Gary Madaras, Ph.D., Assoc. AIA, an acoustics specialist with Rockfon, Chicago. “Since then, there have also been a couple of bad building phases where people thought open plan schools were a good idea. So, the problem is that too many bad sounding schools, built before the current awareness of the importance of classroom acoustics, are still being used,” he said. “About 15 years ago, the acoustics industry got together and developed a standard: ANSI S12.60 (2002) Acoustical Performance Criteria, Design Requirements and Guidelines for Schools. That was a huge step in that it defined for educators and designers how to build classrooms with good acoustics for efficient and accurate communication. This standard is also referenced now by LEED when designing schools and CHPS (Collaborative for High Performance Schools, Sacramento, CA),” Madaras explained. Robert Marshall, manager of marketing technical services, CertainTeed Ceilings, Valley Forge, PA, sees a similar progression in classroom acoustics and particularly credits LEED with increased attention to the acoustic per-

classroom acoustics construction phases, the value placed on this often gets pushed aside or minimized in order to meet other drivers, such as cost.” CAUSES
Poor classroom acoustics generally can be attributed to a handful of recurring and generally recognized factors. One of these is signal-to-noise ratio and the other is reverberation. Noise from outside or from mechanical systems factors into the signal-to-noise ratio. “The signal is the teacher’s voice—the sound that is good and needs to be heard. The noise part of the ratio is anything that can interfere with the signal, and there are a lot of sounds that can do that: traffic noise or plane flyovers transmitting through the windows, heating and air conditioning equipment located inside the classrooms, and occupant noise transmitting through the door to the corridor,” explained Rokfon’s Madaras. “One other type of noise that is often overlooked, but interferes with the teacher’s voice, is reverberation. When the teacher speaks, the first sounds that arrive at the students’ ears are very useful and important. They are the necessary signal. But, if the room has a lot of sound reflective surfaces, the teacher’s voice bounces around inside the room, interfering with the intelligibility of the subsequent words,” Madaras said. The geometric form of the room also is a factor in classroom acoustics. “Is sound energy evenly distributed in a space, or are there ‘hot’ and ‘dead’ spots?” asked Scott Riedel. “Interior finish materials are important. The ratio of sound-reflective to sound-absorbing materials is important, as is their placement to achieve clear and even sound distribution,” he added. SOLUTIONS
“An acoustical ceiling with high NRC (noise reduction coefficient) and high CAC (ceiling attenuation class) will provide absorption to reduce the reverberation and blocking to reduce the intrusion of sound from mechanical equipment and neighboring activity. In addition, wall treatments can be used to further reduce Top. This multi-purpose meeting room and cafeteria features sound-absorbing treatments to reduce ambient and background sound. At the same time, some sound-reflective and -diffusing treatments support and distribute speech and music during activities and presentations. Photo: Scott R. Riedel and Associates.

higher the NRC of the material, the faster you decrease reverberation,” Rockfon’s Madaras said. He continued, “Older schools may have suspended acoustic ceiling tile, but there’s a good chance that they still don’t reach the goal reverberation time because the older ceiling tiles have very low NRC values of 0.60, 0.50 or less. It’s relatively easy to bring a classroom into compliance with the maximum reverberation time criterion in ANSI S12.60 by swapping the existing ceiling tiles with high-performing ceiling panels of NRC 0.90 or higher. The suspension grid can be reused.” “Depending on the problem or deficiency, it is always more challenging to remedy the situation after the fact, and usually more costly,” USG’s Mark Kemerling said. “First and foremost, if a school finds itself in this situation, they should consult a professional ac-

tion of students and the well-being of teachers.” Quiet classrooms are much more necessary for students that have learning or developmental disabilities, students who have had ear buds in their ears for too long and have lost hearing that nobody should lose at that age, and students who, on any given day, may have an ear infection or a cold that limits their hearing by 20% to 25%. All of these kids are mainstreamed into a single classroom where the normal-hearing student is sometimes a minority. “The people occupying these seats are not just those students in need of a quiet classroom; they’re students with needs beyond those of a normal-hearing person,” CertainTeed’s Marshall said. “In the end, it seems to always be about tradeoffs. In today’s environment of tight budgets and compressed design and construction schedules, the ‘acoustic lobby’ gets overshadowed by other things. Like many other important design rules, until it is in the code in a quantifiable and measurable performance metric, it will continue to get minimized. One way to guarantee better acoustics would be to build post-occupancy acoustic performance metrics. Essentially, setting minimum standards for acoustic performance based on the functionality of each space and linking this performance to the government funds would help support these schools. This would drive change,” said USG’s Mark Kemerling. While progress has been made toward quiet classrooms where speech intelligibility levels meet the needs of all students, not just normal-hearing individuals, and where teachers do not have to raise their voices to be heard, architects, designers, and school officials need to join together to make classroom acoustics a universal priority, not an afterthought or a tradeoff.

International Magnet School for Global Citizenship in South Windsor, CT Architect: Perkins Eastman; Contractor: Cutter Enterprises; Installer: The Imperial Company Profile: SNAP-CLAD Metal Roofing; Colors: Hartford Green & Dark Bronze
Metal standing seam roofs of nearby New England barns are recreated on the International Magnet School for Global Citizenship using SNAP-CLAD Metal Roofing Designed in a village configuration, the new 65,000 sq. ft. magnet school blends beautifully with the Connecticut countryside. The three-story, circular media center is roofed with Petersen’s 16” Snap-Clad metal panels that were segmented to create the
radius. The pitched roofs on the four adjoining structures also use Snap-Clad panels. More than 22,000 sq. ft. of Snap-Clad .040 aluminum panels finished in Hartford Green and Dark Bronze were installed — colors that complemented the brick and concrete masonry façade.

Propane generator Ecopower cogeneration system: • Uses propane generator • 90% electric and thermal effi ciency • Emits less CO 2 than traditional power plant
Data-analysis software
The company’s Intelligent Equipment platform uses Internet of Things (IoT) technology. Developed in collaboration with Intel and Wind River, the technology allows building owners to reportedly harness large volumes of data for analysis, moving the industry toward intelligent building systems that intuitively know what building occupants need in terms of comfort, service, and efficiency. Daikin Applied, Minneapolis Circle 71
Security cameras
Enhancements to the Sarix Professional Range IP camera include edge storage, increased compatibility, and versatile camera options. Features include ONVIF profile G compliance, Lenel integration, and additional mounts and options. Edge storage ensures storage of video, audio, and metadata to an SD card directly in the camera for uninterrupted monitoring if the connection to the VMS is lost. Smoked domes are also available. Pelco by Schneider Electric, Clovis, CA Circle 72
The ecopower micro cogeneration system (microCHP) uses a propane generator. The unit produces as much as 4.7 kW with as much as 90% total electric and thermal efficiency. It reportedly serves as a reliable heating and electricity source in locations compromised by the absence of gas mains and reliable power grids. The system is said to emit significantly less carbon dioxide than a traditional power plant. Waste heat is recovered through the system and recycled. The unit is said to be no louder than a refrigerator. Applications include schools, daycare centers, and hotels. Marathon Engine Systems, East Troy, WI Circle 70
Varco Pruden’s Innovative Daylighting Solution
PRISMAX SL
™
PrisMAX SL provides more light for longer periods of the day, enhancing a wide variety of indoor activities for customers, employees and visitors in your facility. These durable skylights use prismatic lens technology to deliver optimal daylight performance. PrisMAX SL was developed in conjunction with Sunoptics™ and when used as part of a sensored-controlled lighting package reduces the need for electrical lighting.
Uninterruptible power system
An enhanced model 93PM UPS is said to provide 50 kW of internal redundancy at full load. The unit provides efficiency to 99% through the company’s EES energy saver system mode and 97% in double-conversion mode. With a compact physical footprint, the system reportedly delivers true modular redundancy, negating the need to purchase a second model for paralleled reliability in most applications. With thermal-management options that accommodate in-row, wall, or aisle installations, the unit is said to be easy to configure and deploy with line and match accessory cabinets that have a wide range of distribution options.
Designed to work on Varco Pruden’s SSR™ or HWR™ roof systems, PrisMAX SL’s unique “self-curbing” structure uses a patented water-diverter and seam-mounted aluminum framing to create a long term, weathertight seal for years of maintenance-free performance.

Project Highlights • LED lighting sources emit radiation in only the visible spectrum, which creates a gentler environment for delicate artifacts. • The lighting system (sources and controls) reduces energy demand by 20 kW/ hr., with an estimated additional 6 kW/hr. in space cooling mitigated seasonally. • The lighting system automatically dims gallery lighting when galleries are unoccupied, adding another level of energy savings and irreplaceable artifact protection. • A central lighting control allows the staff to easily change the facility-wide time clock, occupancy, or intensity settings from any internet-connected device.
across the space with a high color-rendering index (CRI) of 85 to 95, ensuring the History Center’s attractions are viewed in the best light possible. The Sylvania Ultra LED lamps use LED technology to provide energy-efficient alternatives to traditional lighting technologies. Designed to be a direct replacement for standard incandescent, halogen, and compact-fluorescent lamps, the Ultra series of lamps offers increased lumen output, dimming functionality, attractive styling, and the flexibility of indoor and outdoor use. While achieving the goals of preservation and improved illumination, the LED lamps also reduced the center’s lighting energy consumption by 61,500 kWh annually, a roughly 80% reduction from the previous system, resulting in an annual energy cost savings of $9,840. Additionally, the LED lamps have a 50,000-hr. lamp life, 25 times longer than the incandescent lamps they replaced, resulting in $2,656 in annual maintenance cost savings. “Our lighting system is simple to use. It’s perfect for a museum as far as function, maintenance, artifact care, and the visitor experience. We enjoy using it both for regular operations and special events. We plan to carry this retrofit even further in the future for the archive/library level,” Oscar Urruita, facilities manager, SDHC, stated on the museum’s web site. CBP
