PROJECT PLANNING
ENVIRONMENTAL FACTORS
• Ensure ambient noise levels from HVAC are NC rated 40 dB or lower
• Avoid decor featuring a busy background or wall color
• Locate doors with a window or viewing hole at the rear of the room
• Soft surfaces and acoustical ceiling tiles impact audio and reduce sound reflectivity and reverberation
LIGHTING PLACEMENT
• In larger rooms, locate a dimmable light switch at the door as well as the podium location
• Provide the ability to turn off the bank of lights closest to the screen
• Ensure projector location is not directly below overhead lighting
• Avoid positioning cameras facing towards windows
PROJECTION REQUIREMENTS
• Ceiling heights of at least 9 feet are recommended for projection
• Final electrical placement should occur after the projector is installed
• A quad outlet is suggested
• Shades or window treatments are
recommended for rooms with projection
• Projector output brightness needs to
achieve 50ftL for rooms with some ambient light and 75ftL+ with high or uncontrolled light
• Ambient Light Rejecting screens improve image visibility and solve for challenging rooms and layouts
• Wall-mounted screens require backing at the mounting points
• Viewing angles range between 35˚-90˚, based on screen surface
FLAT PANEL MONITORS
• Flat panel quad outlet placement centered on mounting location between studs
• Typical outlet height measures 60” to 72” on center, depending on screen size and location
• Consider using a recessed media box behind the monitor
• LCD’s have a maximum viewing angle of 35˚ to ensure color uniformity
• For large wall-mounted displays, a plywood wall backing with separate provisions for outlet and low voltage cabling is suggested
AUDIO CONSIDERATIONS
• If room seats more than 12 people, sound reinforcement is recommended
• Ceiling speakers are recommended for large conference and projection rooms
• Speaker quantity/quality depends on room size, ceiling height and application
• For room occupancy over 40, microphones should be use for speech reinforcement
• Place microphones away from noise sources (HVAC equipment or projectors)
• Sound masking recommended for speech privacy outside of room entrances but not within the room
CABLES & CONNECTIVITY
• For low voltage cable pulls, a .75”-1.5” conduit is recommended
• Most video signals utilize twisted pair category cabling
• The most commonly used interconnect cables are HDMI, DisplayPort, USB-3.0, USB-C and Cat5e/6
• Wireless presentation solutions are common but require a robust network infrastructure
• Devices need extra-deep rough-in boxes for wall plates and touch panels
• Specify plenum rated cables
FURNITURE CONSIDERATION
• Depending on room, incorporate a podium or adjustable height desk
• Tables must have built-in cable management and AC power
• Cable trenches, over-the-floor raceway or core drills allow connectivity from table to presentation system and prevents a tripping hazard
• Ventilation needs depend on equipment types and thermal load
• To protect monitors and a location for system components, consider placing a table or credenza under monitor
Whether you are moving to a new space or renovating your current office, it is important to include your audio visual technology needs into your overall project planning. EPA recommends the following considerations when planning your next project.
