KJWW Engineer to Speak on Innovation in Control Room Design
[more]
|
|
|
The new production studio and control room at Curtis, Inc., in Cincinnati, Ohio, includes a "Reflection-Free Zone" and adjustable acoustics in its design, giving sound designers more flexibility. Fewer than 75 control rooms in the United States are set up this way, rather than the conventional "live end/dead end" (LEDE) design.
KJWW Senior Engineer Jon Mooney will speak about the details of this design next week at the meeting of the Acoustical Society of America in Portland, Ore. "This design does away with the pre-supposition that the room has to be dead," Mooney said. Instead, the RFZ allows the sound designer to adjust the liveliness of the room for their use.
A LEDE control room is designed to absorb all reflections from the speakers in the front of the room. One problem with this design is that it makes the whole room relatively dead – the sound is heard once from the speakers, and then all reflections are quickly absorbed by the room. A Reflection Free Zone allows the room to still have reflections, but they are not heard immediately by the sound engineer. The design directs speaker reflections from the front of the room away from the recording engineer and extends the initial time delay without requiring a "dead" front end. "This creates a much livelier sound because you didn’t absorb all of that energy to begin with," Mooney said.
The initial time delay, which is the amount of time between when the sound designer hears the sound from the speakers and when he hears it coming from reflections in the room, can be adjusted for different effects. This also has the benefit of making the room sound larger than it actually is, if necessary.
The control room features beautiful, cherry wall storage cabinets that serve triple duty as acoustic treatments with doors that can be opened in varying degrees to adjust the absorption and diffusion within the space. The sound designer can adjust the reverberation of the room to create the best sound. The cabinet doors can be opened to create a fairly dead room as well, giving the sound designer the option of a traditional-sounding control room.
The studio also features variable acoustics in its design; large hinged boxes attached to the walls (affectionately known as "wall coffins") that allow the reverberation and diffusion of the studio to be easily adjusted over a wide range.
"Acoustically the control room feels very open, acoustically diffusive," said Jon Brennan, Sound Designer and Music Composer at Curtis, Inc. " The room is a bit more lively than other control rooms; however, opening the diffuser doors has a large effect on lowering the reverberation time and focusing the sound, direct from the speakers."
KJWW also put together a manual for Curtis, Inc., with instructions on how to operate the variable acoustic components of both the studio and control room to achieve desired acoustic effects. "Recording engineers have their own favorite sounds," Mooney said. "It’s our job as acoustic consultants not to dictate what that environment should be, but allow the recording engineer to be the test pilot and judge for themselves what that should be."
Recording with adjustable acoustics changes the way recording is done, Brennan said. In other studios it is common to place a performer in a desired area of the room with certain acoustics, like a live area vs. a dead area. With adjustable acoustics, the entire room can be tuned or tailored to a specific performance. This adds a greater flexibility not otherwise possible.
In addition to monitoring and mixing, Brennan has found the acoustics and low noise floor of the control room to be ideal for the recording of sound effects. When recording sound effects, it is important to be able to record and manipulate sound in the control room. There often isn’t time to setup mics in the studio and call a 2nd engineer to run the session. We keep a mic ‘live’ on the mixing desk to capture that moment’s creative inspiration. "Both rooms have proven to be very versatile and great sounding," he said. Click here or try this for demonstration video. Video also available on YouTube

KJWW's Headquarters Certified as Quad Cities' First LEED Building
[more]
|
|
|
The United States Green Building Council this week named the expansion to KJWW Engineering Consultants corporate headquarters in Rock Island as the Quad Cities’ first LEED-certified building.
The 17,700-SF expansion was awarded a LEED Silver Certification. Several other building projects in the area are registered with the USGBC as pursuing a LEED designation; however, none have yet been certified, according to www.usgbc.org. The Leadership in Energy and Environmental Design (LEED) Green Building Rating System is a certification program and the nationally-accepted benchmark for the design, construction and operation of green buildings. The certification verifies a project is environmentally responsible, profitable and a healthy place to live and work.
Utility bills show the new addition uses less energy per square foot than the existing building, even though the new building uses substantially more glass for daylighting and views.
The energy efficient design of KJWW’s expansion includes the use of occupancy and daylight sensors in offices and conference rooms. Occupancy sensors turn off the lights if no one is in the space. Daylight sensors limit how many lamps may energize if adequate daylight is present. Daylight is available to more than 75 percent of interior spaces. Ventilation is provided with a 100 percent outside air unit and ducted directly into each cubicle, office and conference room to optimize indoor air quality. An energy recovery wheel is used on the ventilation system to reduce energy consumption and precondition outside air. More than 95 percent of construction waste (by weight) was diverted from the landfill and recycled. Much of this was existing concrete and asphalt, but construction waste such as wood, metal and cardboard also was recycled. Certified wood from responsibly-harvested forests was used for exterior sheathing and blocking.
Low contaminant-emitting adhesives, paints, sealants and carpets were specified in the design.

KJWW Named in National Ranking of Top 100 Green Design firms
[more]
|
|
|
KJWW Engineering Consultants, of Rock Island, Ill, is rated by Engineering News-Record magazine (ENR) as one of the nation’s top 100 green design firms in the nation.
In its first Top Green Design Firms survey, ENR ranked KJWW as 98th with 3 percent of its total revenue in green design last year. The survey measures the green design market based on firms’ 2007 design revenue from projects registered with, and actively seeking LEED® (Leadership in Energy and Environmental Design) certification. The certification is from a third-party rating group – the U.S. Green Building Council.
KJWW currently has 44 LEED-accredited professionals on staff and in 2007 did $1.54 million in green design work.
"KJWW promotes the use of our LEED professionals on project design teams," said KJWW President Paul VanDuyne, PE. "Our emphasis on energy efficiency and environmental sustainability help minimize the impact of the buildings we design."
ENR’s article notes that green building for several years was seen as a novelty, or an extra in building design, but with the sudden surge in energy prices, building green is "no longer an expensive luxury, but an often cost-effective alternative to traditional design."
The Top 100 green design firms generated design revenue of $1.74 billion from green projects in 2007. It accounted for 7.4 percent of the Top 100’s total design revenue.
More than 50 of KJWW’s current projects are seeking LEED certifications, including two projects seeking the highest LEED certification of Platinum. KJWW also is seeking LEED Silver Certification for its recent 17,700-SF expansion to its corporate headquarters.

[more]
|
|
|
KJWW Engineering Consultants is pleased to announce that Kelly Altes, PE, was recognized as one of the top 40 building industry engineers for 2009 by Consulting-Specifying Engineer magazine.
This award is given to engineers under the age of 40 (as of May 1) who stand out in their academic, professional, personal and community achievements. Candidates were nominated by a professional colleague and were judged based on commitment to excellence in a variety of areas, according to the magazine.
The May Specifiers Guide of Consulting-Specifying Engineer magazine profiles each young professional, highlighting circumstances that lead them to success, and highlights recent professional projects and personal achievements.
Altes, a senior engineer at KJWW, is a 2001 graduate of Iowa State University with a bachelor’s degree in civil engineering. She has been a structural engineer with KJWW since 2001. Her expertise is in the design of structural systems including condition studies and evaluations, system comparisons and preparation of plans and specifications for various building types utilizing wood, masonry, reinforced concrete, cold form, aluminum and structural steel.
Altes also serves as the structural department supervisor for the Des Moines office.
"Our 40 Under 40 honorees excel in various areas of the building and construction industry: mechanical, electrical, or plumbing (MEP) engineering or associated professions," said Michael Ivanovich, editor-in-chief, Consulting-Specifying Engineer. "These leaders really stand out in their profession while also achieving work-life balance and serving their communities. These 40 winners are the mentors of the future and are inspirational role models for young engineers and building professionals."

KJWW Engineering Consultants is pleased to announce that Vice President Warren L. Lloyd, PE, LEED AP, was named one of Engineering News-Record’s Top 25 Newsmakers of 2008. The winners were chosen for innovation and achievements in the building, design and construction industry that were featured in the publication during the previous year. ENR is a leading design and construction industry publication.
Lloyd was honored for his work on the country’s largest lake-coupled geothermal system for the $200 million Sherman Hospital project in Elgin. The 650,000 SF greenfield replacement hospital is a leader in innovative design and economic and environmental stewardship.
According to ENR, Lloyd "was recognized for dramatically reducing energy costs with super-sized geothermal systems. Sustainable air-handling is a reality, thanks to him. He proved it in 2000 with a geothermal system at the Great River Medical Center in Iowa and continues to be an objective green advisor to people interested in producing power on-site."
The 255-bed hospital offers spectacular views across a 15-acre man-made lake to a forest preserve beyond. The lake serves as the energy source for the geothermal system. Lloyd "made the case for hospital owners to go green and save big bucks by proving out large scale, geothermal heat exchangers," ENR said.
The system is estimated to save 30 to 40 percent of Sherman’s space-conditioning costs and upwards of a million dollars a year, making it one of the most energy efficient healthcare facilities in the world. The system qualified Sherman for nearly $1.4 million in state and federal grants.
Lloyd has a bachelor’s degree in mechanical engineering and recently celebrated his 25th anniversary with KJWW. He serves as corporate vice president of engineering for the firm. He specializes in engineering-intensive facilities requiring strict control of humidity, temperature and indoor air quality such as laboratories, hospitals, museums, libraries and industrial plants.
He was selected for the award from a large pool of nominees judged by ENR editors to have made the "most important contributions to the industry and the public in 2008."
