PLANNING & DESIGN OF A CONTROL ROOM

Environmental Design

The provision of an appropriate working environment is essential for control rooms that must accommodate auditory or visual tasks. Where speech communication is important, all auditory needs of the environment must be appropriately specified. Ambient noise levels need to be controlled by considering such factors as room and console finishes, noise output of equipment and control of external sources of noise. Ceiling acoustics should strive to achieve an NRC (noise reduction coefficient, a measurement of sound absorption characteristics) of 0.65 to 0.75 or better and an AC (articulation class, a measurement of sound attenuation) of 40 to 44 or better.

Air quality and air temperature can play an important part in keeping operators awake and alert, one of the most common criticisms of control room design is a lack of consistent ambient temperature. An example of how environmental design can contribute directly to operator performance is an air-conditioning system that is automatically set to increase the ambient temperature to compensate for natural early-morning drops in body temperature. Room temperature should range from 70 degrees to 72 degrees F, with relative humidity from 40 percent to 65 percent and minimal air movement not exceeding 4’to 6 per second.

To maintain the most consistent operator environment, a separate equipment room should be provided to house CPUs, servers, and other rack-mount equipment. This will remove the biggest sources of heat from disk arrays and processors and noise from cooling fans from the operators’ area. It also has the benefit of locating the most sensitive equipment in a secure, limited access area that is designed for proper cooling.

Wherever extensive arrays of displays are used, lighting within control rooms should be sufficient and suitable for all visual tasks. A lighting scheme largely based on indirect ambient lighting, where the ceiling reflects light down into the room, has been found to offer an effective solution. In designing a lighting scheme, attention needs to be given to the range of tasks undertaken as well as the ages of the operators. Low levels of lighting may be fine for image monitoring but can pose problems with paper-based tasks. Operators of all ages, but especially older workers, will require adjustable task lighting to conduct small-scale visual tasks.

Ceiling materials should offer moderate to high reflectance of 0.8 or more to improve light distribution throughout the room and reduce energy costs for lighting. Walls should be an off-white matte or flat finish with a reflectance range of 0.5 to 0.6. Floor materials should have a lower reflectance of 0.2 to 0.3 for carpet or 0.25 to 0.45 for floor tiles.

Operators typically do not like working in windowless environments. Unless prescribed for operational or security reasons, it is strongly recommended that north-facing windows be included in a control room, primarily for psychological reasons. However, such light sources also pose potential security challenges and can contribute to reflections and   glare. Windows and doors should be off the primary field of view but visible from a seated position. All-ow circulation space around doors to minimize congestion.

Although a rectangular room provides the most possible options for equipment, display, and console positioning, in general, rooms with sharply angled walls or with support columns should be avoided. Designing a control room of the right size and shape can go a long way toward achieving an efficient, comfortable operating environment.

 
OPERATOR CONSIDERATIONS
When designing a control room, the following steps should be taken to ensure operator comfort and safety:
Testconsole layout with users for”Human Tasks including sequential task simulationi If necessary, modify console layouts based on trial feedback.
Develop workstation layouts designed around acceptable reach zones and visual limitations.
Take into account maintenance requirements and removal of equipment from both the rear and front of the Workstation.
Provide ergonomic footrests where appropriate.
Provide 24/7 chairs with full adjustment capabilities.
Reduce excess heat and noise by locating electronics in an equipment room.
In workstation dimensions, consider the full height range and size range of the users.
Displays/Monitors cont.
when screen resolution increases, it means the operator can get closer to the display and still not be able to detect the individual pixels. Still, it is important to keep in mind that there are practical limits to the size of displays. A quick rule of thumb for viewing video images is that the operator should be at least twice the distance from the screen as the width of the display. A more precise set of guidelines, based on screen diagonal size and image resolution, is explained in Figure 3. To calculate display width, remember that today’s displays often employ a 16:9 aspect ratio. Using a 9:16:18 ratio (height: width: diagonal), the width of a 20” diagonal screen will be 18’ and the height will be 10 Moderate to high-resolution monitors ranging from 15” to 21” diagonal measurements are typically appropriate for primary displays.

Touch-screen technology is also affecting the ergonomics of new console designs, especially in high-security or high-attention environments. While touch screens 12 Screen are not used in many applications, new studies show that when some operators 9” Screen get extremely nervous or come under high stress, they have trouble operating a mouse to find and click on an icon. But typically they have less trouble pointing with their finger to an element on a touch screen. As a result, touch screens are becoming more and more prevalent in high-security, high-stress,or control room applications. However, consoles incorporating touch-screen technology must offer a shorter distance between the operator and the screen - typically less than 28” from the edge of the console worksurface -  so that the screen can comfortably be touched from a relaxed sitting position.

Whatever the hardware interface, the ideal is a design in which operator attention is focused on a single source of vital information relevant to each situation. To minimize head and extreme eye movement, the primary images to be viewed, whether displayed locally or on a distant video wall, should be centered within a 30 degree cone. To calculate the minimum distance, multiply the width of the display times 1.87. Thus, using our previous 9:16:18 example, a 20”diagonal display will have a width of 1 8 meaning that the minimum distance from the display should be 34 If the design calls for two 50’displays, then the nearest operator needs to be at least 6’l0” from the displays: (44 x 1.87).

   

Control Room Layout
Issues to consider when designing console placement in the control room include the room’s dimensions, the number of stations, the dimensions of each station, the dimensions of any video wall, and the width of the aisles.
The distance from which to view a large-screen display or group of displays should not be less than twice the display’s width or greater than 6 times its width for normal video. However, if this is a primary monitor for the operator, where it should fit into the 30 degree cone of viewing, then the longer-range formula of screen width x 1.87, should take precedence.

As an example, consider a console that is 39’ deep, and an aisle that is 42’ wide, for a total of8l If the plan is to use one 75’ diagonal display, here is how you would calculate the room layout:

The first row of operators will be 10’5’ from the front (1.87 times the 67” width of a 75” diagonal screen).

The back row will be no more than 33’6’ from the front (6 times the 67” width of a 75” diagonal screen).

This will permit a maximum of four rows of consoles and three aisles, to keep within the maximum distance. The first row at 1 25’deep may be up to 1 5’3” wide (2 x (distance from front - half the screen width) or 2 x (125- 33.5)). The second row at 206”(l 25 + 81) may be up to 28’8” wide. The third row at 287” (125 + 81 + 81) may be up to 423’ wide. The fourth row at 368’( 125 + 81 + 81 + 81) may be up to 55’8” wide.

Alternatively, you might be asked to determine the proper size for a large screen display, given certain room dimensions. The same formulas apply.

A command control room should be designed for more than just day-to-day operations. You need to consider every situation in the initial design and for future upgrades. Enough space should be maintained in and around the console so that multiple groups of personnel. from supervisors to security professionals, emergency service personnel, or even government officials, can view and analyze information quickly and efficiently. Design for crisis - hope for routine.
