AccessibilityTextAll instruction materials have font size greater the 20pt with high contrast between font and background.
AccessibilityReachesReaches to all wall and podium mounted devices and controls complies with ADA standards. Wall controls are placed at 48". Podium surface can be lowered to 28". Reach across podium to devices is less than 24".
AcousticsSound LevelsClassrooms shall be designed with background sound levels not exceeding an STC Rating of 50. Rooms with less that 10,000 cubic feet must have T60 < .6 seconds. Rooms < 20,000 cubic feet must have T60 < .7 seconds measure ate 500, 1k and 2k Hz.
ArchitectureCeilingThe ceiling height should be 10.5 as a minimum to allow for proper viewing angles and especially viewing the bottom of the screen from the rear of the room. T-bar ceiling should be installed to improve acoustics, improve look and feel, and provide lighting and pathway access.
ArchitectureDoorEntry doors into the classroom should have a window (minimum size 18 x 18) for viewing the classroom from the hallway. The bottom of these windows should accommodate ATI or ADA specifications for viewing from a wheelchair. Main entry should be away from instructors area to prevent disruption by late-comers.
ArchitectureProjection ScreenThe projection screen should be slightly offset furthest from the podium side of the room to allow for a minimum of 12' whiteboard space to be seen when the screen is down. The screen should be angled as necessary to provide greater than 30 viewing angle for all students. The bottom of the screen should be 48 to allow for viewing over seated students. Screen should be matte white, 16:10 ratio, and able to be controlled from podium.
ArchitectureRoom DimensionsAt the front of the classroom, there should be as close to 36' of wall space as possible for instructional use. Room dimensions should have a ratio of less that 1.5:1.
AVControl SystemA touch screen system with push-button redundancy is preferred. Switching and control equipment should be able to be remotely controlled via a centralized network control system. Control system should comply with existing campus Extron standards.
AVProjectorA ceiling-mounted projector of sufficient lumens will be mounted at the appropriate distance to enable the correct throw for the main projection screen. Horizontal vertical keystoning should be avoided using layout and optical lenses without having to use digital keystone correction. Projector should have resolution of 1280x800 or greater and be 16:10 ratio. Projector must be able be controlled via IP or RS-232.
AVSound ReinforcementMicrophones and hearing assistance equipment should be added in tiered seating spaces.
AVSpeakersProgram speakers should be to left and right of screen, not the far sides of the room. Reinforcement speakers should be ceiling mounted away from podium and allow for even disbursement of sound across room.
ElectricalPowerQuad 20 amp power is required under the podium and above the projector. Duplex power should be available at the ADA station.
EquipmentPCPC should conform to campus standards for both hardware, software, and security. Software should be consistent across all classrooms and be determined through consultation with faculty.
EquipmentDocument CameraDoc Cam should be capable of 1280x800 or higher. Should be able to zoom and automatically correct for lighting. Doc Cam should be able to be lowered when not in use to reduce impact on line of sight.
EquipmentMonitorMonitor should mirror what is shown on projection screen to prevent confusion for users. Monitor resolution and aspect ratio should match projector resolution of 1280x800. Monitor should be mounted to minimize interference with line of sight and instructor surface area.
FinishesCarpetingCarpeting should be installed to reduce noise, improve look and feel, and absorb higher frequency reverberation.
FinishesCeilingThe treatment selected for the ceiling should have a minimum NRC of 0.65. In larger spaces, some hard ceiling above the instructor may improve voice reinforcement.
FinishesWall PanelsEach classroom shall be treated with 2, fabric covered, acoustical wall panels mounted above the chair rail on the rear wall (opposite the front instructional wall). Panels typically cover between 10-20%. These panels shall be designed and certified to meet the RT/60 reverberation standards of .6 seconds or less. If free wall space in the rear of classrooms is inadequate to meet the required standards, up to of the side walls shall also be treated.
FinishesWhite BoardsThere should be a minimum of 12' of free white board space without interference from the screen, podium, or other obstructions.
FinishesWindow TreatmentWindows should have shades to reduce glare on projection screen.
FurnishingsClockA clock should be placed on the side wall, visible by both students and the instructor. Clock should be synchronized to campus system.
FurnishingsPodiumPodium will provide sufficient surface for instructional materials and should contain a PC with a DVD drive, laptop connection, document camera, and telephone. Podium should be ADA accessible. Presenting at the podium should impact visibility of the whiteboards as little as possible by moving the podium to the side. Students should be able to enter room without impacting instruction at podium. Podium placement should comply with accessibility requirements (5' turning radius or 3' accessibility on all sides) with 42" preferred between podium and front wall.
FurnishingsWhiteboardsWhite boards should be used in all rooms, with as many linear feet as possible up to 32. There should be a minimum of 12 of free white board space without interference from the screen or other obstructions.
FurnishingsSeatingSeating should have 15 year manufacturer's warrantee. Seating should be padded for comfort. Materials should have high degree of rub, scratch, and stain resistance.
LightingBoard FixturesSpecific lighting for the white boards should be installed, approximately 9-18 inches above the white boards for the length of the boards. Board lights should be able to be independently controlled and be behind the projection screen so that boards can be lit even when screen is down. Board light offset from wall should be 12" or less to projection reduce screen offset.
LightingBulb TypesLights should match campus standard 4100k T8 bulbs in classrooms. Computer labs should have 3500k T8 lights to reduce glare on computer screens.
LightingCeiling FixturesDirect/indirect fixtures with a ratio of no less that 85% indirect should be used for new installations and renovations. Surface mount or drop in indirect after are the next most desirable. Lighting ground clearance, impact on projector beam, screen height, and ceiling height must be accounted for.
LightingLighting ControlA set of light switches should be mounted on the wall near the podium for the ceiling and board lights. At least one switch must be operable at primary entrance. When possible one switch for the board lights, full brightness, and AV mode is desirable. Night lighting must remain on at all times in location furthest from the screen to prevent a complete darkening of room when occupied. Expensive and difficult to program control systems should be avoided. Switched must be clearly labeled.
LightingLighting ProgrammingThere should be three modes for room lighting: full brightness, AV, and all off. Board lights should operate independently.
LightingNight LightingNight lighting must remain on in order to illuminate exit pathways without affecting projection screen.
LightingIntensity The lighting intensity across all student writing surfaces should vary by no more than a 2:1 ratio. The brightest surface should be between 80-100 foot-candles in full brightness mode. Lighting on projection screen should be 1/2 the intensity of both faculty and student writing surfaces in full brightness and AV mode. AV mode should have 1/2 the intensity of full brightness for writing surfaces. Lighting intensity across white boards should vary by no more than a 3:1 ratio and should be at least 50 foot-candles.
TelecommADA1 network drop must be accessible at 30" in the student seating area with nearby power for each 50 seats
TelecommPodium Network6 network drops must be present for PC, laptop, controller, switcher, control interface, and document camera. Additional drops may be required for phone and lecture capture.
TelecommProjector NetworkOne network drop is needed at projector for remote control. A second may be added for future video conferencing.
TelecommPhoneA phone (local access only) should be on the wall behind and close to the podium or on the podium
