1 Purpose This document is aimed at ensuring that learning spaces, meeting rooms and Audio Visual (AV) technologies are implemented in a way that supports the UTAS organisational-wide learning and teaching delivery strategy.

The purpose of this document is to define the University’s standards and requirements for design and installation of AV systems, to ensure that a robust, consistent, flexible, high quality, judicious, sustainable and reliable AV platform is maintained across all UTAS sites that not only meets the current operational needs, but also caters for the provisioning of future AV requirements.

The key objective of this document is to:

• Specify the minimum AV technology and integration requirements;

• A framework to standardise AV technology and infrastructure;

• Define the design criteria being used;

• Provide a means of identifying and upgrading, where required, any sub-standard learning and teaching spaces and other spaces that utilise AV technology

• Facilitate and document an agreed approach for the AV technology infrastructure;

• State the specific requirements for the AV technology infrastructure and for provisioning of new technologies.




All UTAS AV implementations shall use this document, unless a new or specialised room-design is required that is not covered by these standards and specifications. In which case:

• ITS will undertake or oversee the detailed design

• The Chief Information Officer, IT Services and the Executive Director, Commercial Services and Development must sign off on the design

• If practical, the approved new design will be standardised and added to the set of AV standards

This document will be used as attachments to tender documentation when seeking offers for building or refurbishment of learning spaces. It is predominantly aimed at producing correct designs for medium and large teaching spaces with a ‘lecturing’ or ‘group work’ teaching mode. Various parts of the standard shall be applied to smaller room designs and more specific applications.

AC Air Conditioner

ACIF Australian Communications Industry Forum - now called Communications Alliance Ltd (see www.commsalliance.com.au)

ACMA Australian Communications and Media Authority. The authority formed through the merger of the Australian Broadcasting Authority and the Australian Communications Authority on 01 July 2005.

ACCREDITED INSTALLER

In conjunction with the equipment manufacturer's warranty, it is a requirement under current Australian Government regulation administered by the Australian Communications and Media Authority to ensure that the cabling plant is installed by appropriately registered Accredited Installers. Most equipment manufacturers require that these same Accredited Installers undergo supplier specific training in order to maintain the quality and performance of their proprietary systems. The accreditation is specific to the equipment manufacturer's systems for which they have undertaken training to ensure that their equipment is properly installed. From a manufacturer's perspective, utilising Accredited Installers enables them to provide the long-term equipment, system and applications warranties sought by government and other large customers.

4. Have a minimum of 3 x HDMI






5.1.4 Projector Mounting Projector mountings shall:

1. Be secured to the concrete floor slab above or to a substantially constructed rigid mounting point if the slab is not accessible, or if there is no slab;

2. Be positioned according to the optical characteristics of the projector, for optimal projection without the need for image geometry adjustment. The use of image geometry adjustments such as keystone or lens shift is not permitted without prior approval from UTAS;

3. Be positioned at the minimum end of the throw distance range for the desired image size, to optimise projector light output;

4. Include an adjustable length pole to enable the projector to align with the top of the projection screen.

5. Coordinated with other services to ensure that other ceiling mounted utilities such as sprinkler systems, mechanical ducts and light fittings do not interfere with the size and quality of the projected image;

6. Not be mounted to suspended ceiling grids;

7. Twisted pair receivers and other associated components to be mounted on top of the projector and secured using Velcro.

8. Include the UTAS approved locking mechanism to prevent theft and damage.

The accredited Installer is required to verify that the mounting surface will support the weight of the projector, mounting bracket and associated loads imposed during maintenance (technicians supporting themselves on the mounting bracket as they service the projector or climb the ladder).

Projectors at UTAS shall not be mounted in projection booths or bio boxes.

Image shake or vibration should be tested for throughout an install. The possibility any form of image degradation should be investigated during the room scoping at the time of tender. Installation methods shall not cause or exaggerate vibrations in the image.

5.1.5 Projector Commissioning Projectors shall be commissioned using a test pattern generator, or internal test patterns, if the projector is equipped with them.

1. Projector brightness, contrast, colour balance and colour temperature are to be adjusted if necessary to optimise the image quality;

2. The projected image shall comply with ANSI/INFOCOMM 3M-2011 standards for image contrast ratio;

3. The projected image shall be located at an approved height AFFL. (Refer to section 6.1.6.4);

4. Opposing sides of the projected image shall be parallel.




5.1.6 Projected Image Size and Position To enable the detailed content to be read by all the audience, the image must be of sufficient size in proportion to the distance of the furthest audience member. Determination of the screen size must be a result of the strict application of the viewing distance rules below. The aim is to make the screen large enough for those in the back row to read the 10pt body text of a standard website, but not so large as to overwhelm the closest viewer.

There are many variables in trying to determine the maximum and minimum image size; here are some factors that need to be considered:

1. Front wall ceiling height - minimum image height AFFL + maximum possible image height;

2. Fixed screens with a large frame or screens with housing below the ceiling will reduce the maximum image height and need to be factored in;

3. Projected images shall be presented on suitable projection screen surface material (motorised screen, chain pull, or fixed frame dependent on system type, and installation conditions);

4. Projected images must not be presented onto painted wall surfaces, Paint-on-screen specialised paint, or any other materials deemed not suited for displaying projected images;

5. To calculate the required image height, measure the distance to the furthest viewer and divide by 5.3. If it’s not possible to provide an image large enough to service the entire room, then additional supplementary screens may be necessary;

6. Position the screen(s) in a location to ensure that all viewers are within a 45-degree horizontal viewing angle to the centre of the image. If more than 10% of viewers fall outside this rule, then supplementary screens may be necessary;

7. Ensure that the vertical viewing angle is less than 15 degrees to middle of the image, and less than 35 degrees to the top;

8. Finally, the closest viewer should not be closer than twice the image height.

Where a space requires more than one display, the same rules should be applied to ensure that the viewing area falls within the above criteria for each display.

Site conditions, heritage considerations, and other factors sometimes cause difficulty with full compliance to all of the rules, especially during refurbishment projects; however, it’s imperative that the image size and position meets all UTAS AV requirements and AETM guidelines as detailed in the following sections.

5.1.6.1 Ceiling Height Ceiling height calculations are based on the following equation –

(Furthest viewer distance to image ÷ 5.3) + 1.2m = minimum ceiling height.

Distance to Furthest Audience Member (m) Required Ceiling Height (m)

13.9 - 14.4 4.0

For every 0.475m extra distance... Add 0.1m ceiling height

Table 4 – Aspect ratio and minimum image resolution

If the room is longer than 7.5m then the ceiling height must be greater than 2.7m to provide an acceptable image size.




5.1.6.2 Aspect Ratio Only the following aspect ratios and image resolutions are acceptable for projection and LCD displays:

Application Aspect ratio

Minimum Resolution Notes

Single projection display area 16:10 WUXGA

(1920x1200) Preferred aspect ratio, as it allows for correct display of both 16:10 and 16:9 content

Single LCD/LED display area 16:9 FHD

(1920x1080)

Video wall 16:9 UHD (3840x2160)

Multi-display edge blended projector solutions will not be implemented. LCD video wall may be used where appropriate.

Table 5 – Aspect ratio and minimum image resolution

1. For dual display installations each individual display must meet the minimum resolution above;

2. Projected images shall be rectangular with parallel edges and 90-degree corners (no keystone image distortion);

3. Projected images must be presented on suitable projection screen surface material (motorised screen, chain pull, or fixed frame dependent on system type, and installation conditions). Any other surface will not be accepted;

4. Optical image correction via lens shift may be used to correct image positioning;

5. Digital correction of ‘keystone’ or other geometric aberrations must not be employed without UTAS approval. Keystone correction must not exceed 10% (for example, no more than 9 degrees on any 90 degrees angle).

5.1.6.3 Image Size The minimum screen height or maximum allowable viewing distance for a certain screen height depends on what material is being displayed.

The International Communications Industry Association (ICIA) standards specify the following types of viewing tasks applicable to tertiary education:

• Detailed Viewing Tasks (e.g. note taking from text-based slides)

• Inspection Viewing Tasks (e.g. viewing graphic materials such as complex mathematical equations, engineering drawings or medical slides)

Since most classrooms and lecture theatres are general purpose and may cater for both kinds of tasks, AETM recommends that the height of a projection screen or flat panel display shall be no less than the distance from the centre of the screen to the furthest audience member divided by 5.3.




Where ‘H’ is equal to the height of the projection screen, the furthest viewer must be seated no more than a distance equal to 5.3 x H from the centre of the screen.

Conversely, the height of the projected image shall be a minimum of the distance from the centre of the image to the furthest audience member, divided by 5.3.

The table below shows examples of maximum viewing distances (distance to the furthest audience member) for the different viewing tasks.

Table 6 – Examples of maximum distances serviced by standard, commonly available 16:9 and 16:10 screen sizes

If it’s not possible to provide an image large enough to service the entire room, then additional supplementary screens will be necessary.

5.1.6.1 Supplementary Displays Ideally, supplementary display screens should be avoided as AV enabled rooms that cannot support an appropriate sized image should not be selected.

In instances where a room does not provide for a correctly sized / located image for the entire viewing audience, supplementary displays shall be installed. The selection and installation guidelines for a suitably sized and located display (detailed within this document) shall be applied.

5.1.6.1 Confidence Displays Confidence displays required for lecturer/presenter to see the far site audience in a videoconference or content.




5.1.6.2 Vertical Viewing Angle The maximum vertical viewing angle shall be no more than plus or minus 15 degrees from a horizontal line measured at 1250mm AFFL from the front row centre seat to the centre of the image.

5.1.6.3 Horizontal Viewing Angle The maximum horizontal viewing angle shall be no greater than 45 degrees from a line perpendicular to the centre of the image. If more than 10% of viewers fall outside this rule, then additional images shall be necessary.

Ultra-wide video walls should be considered as two screens (as this is a common use case), so measurements should be taken from halfway from the midpoint of the screen on either side.




5.1.6.4 Image Distance from the Floor The minimum distance of the bottom of the image AFFL shall be 1200mm for flat floor spaces, with a preferred height of 1350mm AFFL, or more, however:

1. If the space has tiered seating, the image may be lowered if necessary;

2. If there are obstructions, the image shall be positioned to enable a clear sightline over or around the obstructions, whilst taking maximum viewing angles into account;

3. Consideration shall be given to potential glare from the projector in the eyes of the lecturer;

4. Image position shall be approved by UTAS prior to final positioning of the projector, unless documentation detailing the image position has been supplied by UTAS.

Room type Example Viewable area height Above Finished Floor Level (AFFL)

Tiered floor teaching venues

Lecture theatre

The bottom edge of the viewable area is no less than 1350mm above the floor

Flat floor teaching venues Seminar room

The bottom edge of the viewable area is no less than 1200mm above the floor

Small flat floor rooms Office The bottom edge of the viewable area is no less 900mm, but ideally 1200mm above the floor

Rooms with obstructed line of sight to the displays

Laboratory

The line of sight from seated eye height (1250mm AFFL) plus obstructions needs to be considered for correct positioning of screens and displays. This may require the placement of repeater screens to work around obstacles.

Installations in a non-seated area

Digital signage

Standing eye height (1568mm AFFL) should be used for consideration of the lowest point for the viewable area.

5.1.6.5 Projector Placement The decision on the placement of the projector is also influenced by several considerations:

1. Ease of maintenance

2. Projector noise intrusion

3. Ensuring the presenter’s workable area in front of the screen is free from projector glare

4. The additional cost of telephoto or short throw (wide angle lenses)

5. Security concerns

6. Lectern placement

If the position of the screen allows for the presenter to stand directly in front, then a short throw lens shall be fitted to the projector. This ensure the glare form the projector does not interfere with the presenter.

If the bottom of the screen is 2.0 meters AFFL or higher then the projector placement shall be located based on ease of access for maintenance, this may involve fitting a telephoto or short throw lens.




To ensure a high-quality image, the projector must be installed in the manufacturer’s recommended horizontal and vertical position.

The ability of the presenters to walk in front of the screen without contending with the glare from the projector in their faces is also an important factor to be considered with possible OH&S implications. The closer a projector is to the screen the steeper the angle of light and the more glare free work area is created. See the illustration below:

Short throw technology is only suitable for a screen with a gain of 1 or less to avoid brightness issues at the edges of the picture.

5.1.6.1 Projector Brightness AETM recommend 500 lux as a minimum lux level for any given screen size. This target is progressively more difficult to achieve in large venues. For large venues a more achievable and affordable target for large venues is 300 lux, however this reduced target will only comply with the ANSI contrast ratio standard if the lighting is carefully designed to significantly restrict ambient or spilled light falling on the projection screen(s) and thereby washing out the projected content. The achievement of the 7:1, 15:1 and 50:1 contrast targets mandated by the ANSI standard for contrast ratios must be achieved.

As a general reference the table below provides a guide to the recommended minimum projector light output:

Screen Size Diagonal (mm)

Screen Width (mm)

Screen Height (mm)

Projector ANSI

Lumens

98” (2500) 2150 1350 3000

130” (3300) 2600 1600 4000

197” (5000) 4300 2700 7000

>197” (5000) >4300 >2700 Custom




The below calculators can be used to estimate the projector required for a given purpose. Based on the information of the below calculators, a lumens:lux ratio of around 40:1 is a good rule of thumb to achieve the recommended 500 lux.

This calculator assists in defining the projector specifications required for a given space http://www.digitalprojection.com/emea/calculator/

This calculator provides details about specific projectors and allows for information about a space to be provided to define suitability

http://www.projectorcentral.com/projection-calculator-pro.cfm

5.1.6.1 Projected Luminance Screen luminance (light reflection) at all points on the screen shall be no less than 50 nits. Luminance at the edges of the screen (5% in from each edge) should be not less than 75% and not more than 90% of that at the centre. The distribution of screen luminance should be symmetrical about the geometric centre of the screen.

5.1.6.1 Projected Contrast The contrast ratio (the difference between peak white and black in the projected picture) must exceed defined minimum limits. The contrast ratio achievable in a teaching space depends upon the brightness of the projected image (the peak white) and crucially upon the amount of ambient light falling on the projection surface (which determines the black or minimum level).

In spaces that use projected images the AV systems and lighting systems must be designed to meet the ANSI/INFOCOMM 3M-2011 Projected Image System Contrast Ratio standard: http://webstore.ansi.org/RecordDetail.aspx?sku=ANSI/INFOCOMM+3M-2011

A rule of thumb is for venues of 10m long or less, the target maximum amount of ambient light on the screen shall be 50 Lux with an absolute maximum of 100 Lux, for venues greater than 10m in length this is to be reduced to a target of 30Lux with a maximum of 60 Lux.

8.3 Lighting for Lecture Capture Lecture capture requires an increased level of illumination on the lecturer and whiteboard surface, whilst maintaining lower general light levels that are suitable for projection.

Lighting specific to lecture capture requirements shall be included in spaces with lecture capture capability. Lecture capture lighting shall be remote controllable from the lectern.

Lecture capture lighting shall include:

1. 1 x spotlight to illuminate the lecturer for small spaces.

2. 2 x or more spotlights to illuminate the lecturer for larger spaces

3. 1 x spot or floodlight to illuminate the dry-erase (“whiteboard”) wall section.

Lecturer lighting shall:

1. Be fitted to a ceiling mounted lighting track to allow for adjustment of the lighting position.




2. Be positioned out of the lecturer’s direct line of sight to the audience by between 45 and 60 degrees to prevent the lecturer being dazzled by the light, whilst minimising any shadows on the lecturer’s face.

3. Comprise of focusable fittings equipped with beam shaping and barn doors to minimise spill onto the projected image surface.

4. Comprise of fittings with sufficient light output for image recording.

5. Must ensure that projected image surfaces are not washed out by hotspot and other reflections.

Whiteboard surface lighting shall:

1. Be fitted to a ceiling mounted lighting track, or a wall mount, positioned as close as possible to the “whiteboard” surface, to illuminate the surface whilst minimising the lecturer’s shadow onto the surface.

2. Comprise of fittings equipped with barn doors to minimise spill onto the projected image surface.

3. Comprise of fittings with sufficient light output for image recording.

8.4 Lighting for Videoconferencing Video conference venues are in effect small television studios and require additional care and consideration in lighting design - conventional lecture theatre lighting will not suffice as it will shadow the faces of the people.

The following shall be considered when designing the lighting for videoconferencing spaces:

1. All viewing areas shall be evenly lit and diffused. Light level shall be 550 -770 Lux on the faces of participants

2. Lights shall shine at an angle of 45 degrees to the participants’ faces to light faces evenly and avoid eye shadows

3. An intermediate or warm colour light will give acceptable pictures and emit a comfortable light (3500-4100 Kelvins)

4. Do not use low energy fluorescent lights that operate between 30 and 50 kHz. These lights can interfere with the proper functioning of wireless keypads used for system operations

5. Light should not shine onto display screens and not introduce any glare on the camera lens

6. The use of key and fill light for presenters is recommended.

7. Ideally, the room should not have any exterior windows. If it does, blockout curtains or blockout blinds shall be provided

8.4.1 Lighting Considerations for AV Equipment • Consistent, bright, and warm lighting will produce the optimum image captured by the video

conference camera




• High brightness LCD flat panel displays 500-800 Nits (cd/m2) will produce a sufficiently bright enough image to be clearly visible above the ambient lighting

8.5 Lighting for Demonstrations Demonstration lights must be designed to suit the intended use case of the room where general room is deemed insufficient.

8.6 Lectern Reading Light Spaces equipped with an AV control system shall use the document camera light as the reading light and operated via the touch panel

8.7 Lighting Control Lecture theatres and larger AV equipped spaces shall include lighting control as part of the automation system.

The lighting control systems shall comply with the following standards:

1. IEC 60929. AC Supplied Ballasts for Tubular Fluorescent Lamps – Performance Requirements.

2. IEC 62386. General Requirements for Digital Addressable Lighting Interface.

8.7.1 Lighting System Type The lighting control system shall:

1. Be of manufacture: Philips Dynalite or as specified otherwise by the project

2. Utilise digitally addressable ballasts

3. Be able to control up to 64 fittings per network system

4. Include power cut-off to the ballasts for power saving when the lights are dimmed to 0%.

5. Have a minimum default failsafe level of 50% brightness in the event of a network or control system failure.

8.7.2 Lighting User Control User control of lighting shall typically be implemented from the AV system touchscreen. Also Need to have a light control near entry and exit door on opposite side to door hinge, this must not disable lighting control from AV control panel.

User controls from the touchscreen shall include, but not be limited to:

1. Stage (Front Zone) Lights High, Medium, Low, Off.




2. Room (Other Zones) Lights High, Medium, Low, Off.

3. Presentation Mode On/Off.

Other user controls shall be included where appropriate, including:

1. Lecture Capture Lecturer Spotlight(s) On/Off.

2. Lecture Capture Whiteboard Lighting On/Off.

3. Lecture Capture Mode On/Off.

4. Demonstration Mode On/Off.

8.7.3 Lighting Pre-sets Actual lighting levels in practice will be set primarily to reference Australian Standards (where appropriate). The following lighting control system pre-sets will provide guidance as to the standard lighting design for a larger multi-purpose lecture theatre at UTAS:

1. UTAS Full - Board Lighting or Demonstrations (also used as Entry/Exit lighting without board lights). Board lights to be separately controllable where available. Lighting adjacent to the demonstration area shall be set to maximum; the remainder of the lighting shall be dimmed to appropriate lux levels.

2. UTAS AV - Text and Graphics Projection. This is the most commonly used state.

3. UTAS Dim - Cinema Projection. Projection takes precedence, plus safety lighting, with note- taking light only implemented if achievable without excessive spill.

4. UTAS Off - Everything off except safety lighting.

NOTE:

Maximum dimmer setting shall be 90% of full, for energy conservation and extension of lamp life.

Lighting levels for High, Medium and Low settings shall be determined and adjusted as required by each space.

Assumptions:

• Target Projected Image Lux = 1500+ • Screen Gain = 1

Example A: UTAS Full Mode (demonstration mode)

The lighting (and external light control) must be capable of providing suitable light levels at student writing surfaces to facilitate detailed note taking while simultaneously providing good visibility of notations being made on the whiteboard and/or of the presenter undertaking a physical demonstration in the presentation area, together with a safe level of access light. Projection is generally not required in this mode so there is no specification for contrast ratio on the screen.

Design Lighting Levels




• Note taking light in student seating area shall be capable of producing a minimum of 320 maintained lux measured on the horizontal surface of each student writing bench.

• Separately controllable illumination of presenter to a minimum of 150 lux measured in a horizontal plane and a minimum of 50 lux in the vertical plane within the defined presentation area. Where frontal lighting is used it should be placed as close as practical to 45 degrees elevation and 45 horizontally degrees from a line perpendicular to the screen to avoid undue glare in the presenter’s field of view.

• While the amount of spill light on the screen from all sources is not defined in this mode, if there is a requirement for projection to be simultaneous with board or demonstration lighting, then spill light on the screen shall be limited so that a contrast ratio of 7:1 is achieved between the level of white illumination produced by the projector across the entire screen surface and the level of ambient light incident on the screen.

• Stair treads: refer to applicable Australian standard or local specification

Example B: UTAS AV Mode (text and graphics projection mode)

The lighting (and external light control) must be capable of providing suitable light levels at student writing surfaces to facilitate detailed note taking while simultaneously providing good visibility of the presenter, a safe level of access light and adequate (7:1) contrast ratio on the screen.


• Note taking light in student seating area shall be capable of producing a minimum of 150 maintained Lux measured on the horizontal surface of each student writing bench. This lighting source must be controlled to minimise spill onto the projection surface (see below).

• Separately controllable illumination of presenter to a minimum of 150 maintained Lux measured in a horizontal plane and a minimum of 50 maintained lux in the vertical plane within the defined presentation area. Where frontal lighting is used it should be placed at angles of between 45 and 60 degrees elevation and 45 and 60 degrees horizontally from a line perpendicular to the screen to avoid undue glare in the presenter’s field of view.

• Spill light from all sources to be limited so that when note taking light of 150 Lux is achieved in the audience area, a contrast ratio of 7:1 is achieved between the level of white illumination produced by the projector across the entire screen surface and the level of ambient light incident on the screen.


The specific expected white level from the projector should be confirmed prior to lighting design. However, as an example, where 500 Lux is achieved as projected peak white, spill light from all sources must be <72 Lux at any point within the image area of the screen.

Example C: UTAS Dim Mode (cinema projection mode)

The lighting (and external light control) must be capable of providing adequate (50:1) contrast ratio on the screen, along with a safe level of access light and (if possible) suitable light levels at student writing surfaces to facilitate less comprehensive note taking.





• Spill light from all sources to be limited so that a contrast ratio of 50:1 is achieved between the level of white illumination produced by the projector across the entire screen surface and the level of ambient light incident on the screen.

• The specific expected white level from the projector should be confirmed prior to lighting design. However, as an example, where 500 lux is achieved as projected peak white, spill light from all sources must be <10 lux at any point within the image area of the screen.

• Where practical, note taking light in student seating area shall be capable of producing up to 50 lux measured on the horizontal surface of each student writing bench. Where note taking light cannot be achieved without compromise to the amount of spill light on the screen, then note taking light is to be reduced or eliminated

• Presenter illumination is not required in this mode.


Example D: UTAS Off Mode (all off)

"Everything off" except safety lighting.

Common scenarios

The table below provides an example of the indicative maximum ambient/spilled light limits for different screen sizes. In all cases, the actual contrast ratio shall take precedence.

Room type Diagonal Screen Size metres (inches)

Projector ANSI Lumens

Projected Image Lux

Target ambient Lux (Text / Photo / Movie)

Meeting room 2.54 (100”) 5000 1725 85 / 40 /12

Seminar room 2.92 (115”) 5000 1190 65 / 30 / 9

Seminar room 3.30 (130”) 5000 1020 82 / 38 / 11

Lecture theatre 3.81 (150”) 5000 700 66 / 31 / 9

Lecture theatre 5.08 (200”) 7500 646 55 / 26 / 8

8.8 Lighting Automation The AV control system shall allow for automation of light switching and dimming if required.

8.8.1 Dimmer integration with AV Control Systems • The dimmer network must have either a serial or IP interface and be connected to the AV control

system via IP network cabling.

• The AV control system must be programmed to provide quick access to lighting pre-sets and user accessible slider/fader controls for spot and stage lights




• The AV control system can also automate some functions, such as dimming board lights or closing motorised blinds when projection is selected

• Lighting levels shall be fully and continuously controllable from 100% light output to less than 2%. Control function (i.e. control input versus light output) shall be approximately linear

• "No occupancy" time out and user-initiated lighting and AV system shut down routines must be programmed.

• Dimmers should be in positions that facilitate easy access. They should not be in ceiling cavities or in false floors. Within the cupboard dimmers must be mounted at a height which allows ready access for a standing technician, without using a ladder or having to crouch or kneel down

• The operation of the dimmers must not cause electronic magnetic or any other kind of interference with other systems within the room or in the vicinity

8.8.2 Lighting Automation Utilising Occupancy Detectors (PIRs) Lighting shall be controlled via the AV Control touch panel, manual light switch located at each entry door (opposite side form door hinge) and via occupancy sensor.

Occupancy sensors should be installed as part of all lighting systems. The output of the occupancy sensors will be available to the control system, to allow for energy management of both AV equipment and lighting in the space.

To avoid unwanted AV system shutdowns during longer sessions where people may be stationary for extended periods of time (for example during examinations), the sensor technology should be capable of detecting the presence of stationary occupants and not just those traversing the space. Alternatively shut down timers need to be programmed to accommodate long durations of no movement.

Automated activation and deactivation of lighting shall be done using occupancy detectors in the following configuration:

1. 1 x directional occupancy detector at each entrance to the space for lighting activation and deactivation.

2. 1 x non-directional (360 degree) occupancy detector above the lectern for lighting activation and deactivation.

3. Or solution sufficient for size of the space for lighting activation and deactivation.

4. Occupancy sensors must detect people within 1 meter of entry to the space.

Occupancy detectors shall be passive infra-red or dual technology (infra –red and ultrasonic) type.

The functionality of the automation shall be as follows:

1. AV Control system will control lighting when:

o AV system is on and being operated.

2. Lighting control system will control lighting when:

o AV system is in stand-by.




o AV system is powered off.

3. Upon entry, ‘entry’ PIR’s shall trigger and activate the entry lighting pre-set located adjacent to entry doorways shall be triggered and activate the entry lighting pre-set.

4. AV system power on shall only be controlled from the touch screen located at the lectern.

5. AV system power and room lighting shall be shut down if no activity is detected by the ‘room in use’ PIRs after 90 minutes as per energy management requirements.

o An exception is if an active videoconference call is in place, then AV system power and room lighting will remain on

8.9 Fire, Emergency, Mechanical Services (A/C) and BMS integration

Where required, the AV and lighting system shall be installed and programmed to accept signals from the buildings emergency warning system (EWIS). An emergency signal to the system should trigger the actions determined by regulation e.g.: turning on the lights, muting sound systems other than warning announcements etc.

In many cases it is desirable to connect the room control system to the Building Management System (BMS). This allows the room automation to send signals to the air conditioning regarding lighting states and room occupancy.

8.10 Ambient Light Correct selection, placement and control of light fittings shall be utilised to minimise ambient light spill from the room lighting onto the projection surface.

In cases where a space has external windows, or is open to other areas of a building, some consideration shall be given to minimising ambient light spill from outside the space. This can be achieved using block-out blinds, curtains as well as strong consideration of room orientation etc.)

In cases where there are internal windows such as adjoining rooms or hallways. Some considerations shall be given to minimise ambient light and create privacy. This can be achieved using blinds, curtains, window tint etc.)

In lecture theatres and video conference room motorised block-out blinds or curtains are required and to be controlled by the AV control system.

9 Room Acoustics




Room acoustics is essential to achieving successful and intelligible sound within a space. Technology by itself cannot solve acoustics problems such as reverberation time, background noise or unintelligible speech. Therefore, an acoustic design must be considered when building a new space, or refurbishing existing ones. This includes but not limited to:

• Huddle spaces

• Office installs

• Skype meeting rooms

• Small, medium and large teaching spaces

• Any AV space video conferencing or not

Design of venues shall conform to the relevant standards and in particular;

AS/NZS 2107:2000 Acoustics – Recommended design sound levels and reverberation times for building interiors

AS/NZS ISO 717.1:2004 Acoustics - Rating of sound insulation in buildings and of building elements- Airborne sound insulation

An acoustic consultant must be engaged in the design stage, especially when designing a solution for larger spaces.

The main design criteria are in the areas of ambient sound levels as well as reverberation times. These two criteria relate directly to the speech intelligibility of the space, which is the ultimate measure of acoustics in a teaching space.

The Speech Transmission Index (STI) is a method of measuring speech intelligibility, with “excellent” STI ratings being between 0.75-1.0.

9.1.1 Ambient sound level and reverberation time Achieving appropriate ambient sound levels and reverberation times, will lead to desired STI ratings within a space, and therefore, good audio intelligibility.

Ambient noise levels shall comply with AS2107-2000.

Reverberation times shall comply with AS2107-2000, using the RT60 ratio.

The following guides should be taken into consideration when designing a teaching space:

• Ambient sound levels must not be so high that they become intrusive, nor so low that it causes speech and other noises to be distracting

• Reverberation and all associated audio anomalies such as standing waves, early and late reflections need to be considered

• Room layout, materials and finishes should be carefully chosen to provide the space with good acoustic performance for the required use

• The reduction of shiny surfaces, the use of sound traps and the mitigation of box or rectangular rooms and regular surfaces will reduce the occurrence of standing waves and alleviate most reverberation issues. Reverberation is unavoidable but measures need to be in place to minimise its effect, especially where it makes the delivery of audio unintelligible




• Technology-based solutions are available to address these issues, such as a focussed sound field solution through the use of array-style speaker systems. These solutions can be implemented only in the case where no other option is available.

The below table shows the recommended noise levels and reverberation times required to achieve adequate room acoustics for different type of spaces. This is based on

Type of Space Ambient Noise

Level Best Practice

Ambient Noise Level

Minimum Standard

Typical Reverb Times (*varies with room

volume)

Smaller lecture rooms (<50 seats) 30 dB(A) 35 dB(A) 0.7-1.0*

Lecture Theatres 35 dB(A) 45 dB(A) 0.7-1.0*

Computer Rooms 40 dB(A) 45 dB(A) 0.4-0.6

Meeting rooms 35 dB(A) 40 dB(A) 0.6-0.7

Seminar rooms 30 dB(A) 35 dB(A) 0.4-0.6

Video conference rooms 35dB(A) 40dB(A) 0.6-0.7

9.1.2 Mechanical Services Noise The level of noise from air-conditioning, ventilation and other mechanical equipment has a great impact in the overall room acoustics, and it is one of the most common causes of sound detriment in a teaching space. The following aspects should be considered in order to prevent degradation of sound caused by mechanical services:

• Air handling systems should operate at low velocity to minimise noise • Air handling systems with local Fan Coil Units (FCU) mounted within the room ceiling space are

best located outside the room or fully enclosed in an acoustically rated compartment designed to reduce the FCU noise below the room’s desired ambient noise level

• Low frequency noise must be avoided. Projects engineers need to take all steps to eliminate low frequency noise from mechanical plant compressors, and to minimise the wide band noise generated by faster air flow in ducts and through diffusers




10 Room Finishes and Furniture 10.1.1 Colour palette general guidelines

• No dark or light-coloured table tops. The best table surface colour is a flat satin finish, in neutral grey

• No high gloss or reflective surfaces • No line or grid patterns • Light coloured floor coverings and furniture near the projection screens should be avoided as

much as possible since they will reflect significant amounts of light from the spot and stage lights onto the screens

10.1.2 Wall colour Wall colour should be mid tones, tending towards light in order to give the room a bright atmosphere (e.g. Blue-Sky Blue). Blue is the best tone for the camera to provide balance to skin tone – other colours may result in sickly looking participants.

Acceptable Colours:

• Dulux P35E3 First Landing • Dulux P37D2 Flight Time

•

• Wall colours behind the participants are to be considered. Backgrounds and table tops should not be too dark or too light as this can cause difficulty with camera auto-iris control. Mid tones and moderate lighting levels on background walls will give the best results

• Avoid patterned or woven fabrics and finishes on walls as these can produce moiré patterns or strobing effects when the camera is moved.

10.1.3 Colour Palette for Presentation Surfaces UTAS has a preference for using purpose-built projection surfaces. However, if a projection is to occur onto a painted wall, special paint is to be used for this application. No colour tints are acceptable. A high quality plaster finish including paintwork should be used to ensure the best surface finish possible. The wall must be flat with no bows and vertical.

10.1.4 Colour Palette Behind LCD Displays Dark colours can produce both a restful background and a stylish contrast to the bright LCD image. A dark background also tends to de-emphasise the black frame of the LCD panel, which then blends into the background, rather than standing out and drawing your attention to the frame and hence reminding you that the people in the image are not real.




10.1.5 Flooring Carpet only must be used, no hard surfaces are to be used as this affects room acoustics and room lighting.

10.1.6 Seating Chairs placed in the venues must be upholstered to reduce echo and aid with the acoustics of the room.

In rooms where no tables are provided, seating must have a foldable tablet arm.

Seating must comply with DDA requirements.

10.1.7 Tables Tables in venues should have matt, non-reflective surfaces that do not cause reflection or unwanted light spots in camera situations. The best table surface colour is a flat satin finish, in neutral grey.

Moveable tables must have lockable wheels and folding top for easy storage.

10.1.7.1 Video Conference and Unified Communications Rooms Tables for Video Conference and Unified Communications Rooms should be designed for the best image capture of the faces of seated participants as viewed by a camera installed centre to the table.

The shape of the table should be such that the end closes to the camera is wider than the opposite end. This ensures no seated participants block the view from the camera to participants seated next to them.

Applies to the following room types:

• Polycom VC System – With Touch Panel

• Polycom VC System – Without Touch Panel

• Skype Room System

10.1.8 Ceiling Acoustic ceiling tiles are preferred to provide better room acoustics, easier install and maintenance of ceiling mounted equipment.

All solid set and plaster ceilings must have access hatches for maintenance and servicing of audio visual equipment (Projectors, cameras, et al)

10.1.9 Windows




Windows should be avoided. If windows are to be included in a room, considerations of room purpose must be made as orientation of windows can compromise front and rear cameras and reduce screen contrast and affect general lighting to the presentation location. All windows will be also supplied with blinds or louvres to control external lighting and such that they are capable of full block out.

10.1.10 Curtains and Blinds Plain, mid to light blue curtains can produce a pleasing backdrop that do not distract the viewers and should be loosely gathered otherwise camera auto-focus systems may focus on the vertical edges of the curtain folds rather than on the participants. These are also important for dampening of audio, reducing echo and other distortion. They should be considered preferable to paint where room size and budget allow.

If an audio visual control system is in place, blinds control should be integrated within the system and made available at the AV control interface.

10.1.11 Lectern placement Lecterns need to be positioned at 1500mm from the front wall at a minimum, to comply with AS1428 part 2 for access. They should also be appropriately located as not to block the view of the screen from any seated position.

The preferred orientation is to be squared to the screen and on the opposite side of the room from the entry. Sufficient space must be maintained to allow front and rear doors to fully open and slide out rack. Where a lectern has an overhang, the overhang must face the centre of the room.

Lecterns must be fixed to the floor, with final placement approved by UTAS IT Services project manager.

11 Lecture Recording and Playback Lecture recording and playback (Capture) shall be employed in spaces as per the room designs.

Lecture Capture shall have the ability to record selectable audio of all types of audio, program source audio/video, camera feeds, videoconference audio /video/cameras. Simultaneous dual video recording (i.e. camera and content).

Recording in progress signage must be installed in all spaces with recording capability, that lights up when recordings are initiated. Outside all spaces there must also be signage indicating the space is recording enabled to advise users they may be recorded.

Hardware based recording indicator lights must be placed above and behind lecturer in clear view of the room audience. Minimum height no less than 2.0 meters

Software based recording lights must be placed on the lectern in clear view of the audience and lecturer.

The Lecture Capture system shall be IP based, with a central server for storage and management of recorded material, and recording devices local to equipped rooms for input of AV content.

Current recording platform is Echo360 Active Learning Platform
