Learning spaces should be designed from the “inside-out,” such that the function and the purpose of the classroom are the number one priority of design, not building mechanical systems. Refer to Room Design Considerations below. 

1. Learning spaces should incorporate capabilities to support flexibility of use; furniture, function, collaboration, and technology.  Increased square footage allotted for students increases the degree for classroom flexibility. 

2. Classroom design elements should be inviting to students; breaking away from an “institutional” feel that has dominated classroom design for decades.  The classroom may be configurable such that any wall could be a presentation area.  

3. Learning spaces may incorporate formal and informal learning areas such as meeting spaces, seminar spaces, lecture spaces, conference rooms, and traditional classrooms. 

4. Audio-Visual System design and installation contractors shall have a minimum of 1 AVIXA CTS-D certified member and a CTS-I certified member. 

5. Audio–Visual System infrastructure and components should be reflected in dedicated page(s) in architectural plans, including elevations and mounting details. 

6. Audio–Visual System infrastructure and components should be reflected in Electrical, Telecomm, and Mechanical architectural plans. 

7. All architectural plans that involve learning spaces or audio-visual technology elements shall be commented on during the design phase and approved by Cal Poly ITS Operations representative and classroom designer to ensure conformity to university standards and functionality needs.  

8. Note viewing angles and screen dimensions on construction documents. 

9. Finished ceiling height should be a minimum of 10’ above finished floor in instructional spaces.   

10. Student seating areas should fall within the basic decision-making model range (Powerpoint viewing) based on AVIXA’s V202.01:2016 Standard for Display Image Size for 2D Content in Audiovisual systems 

11. Screen heights should observe a maximum 30-degree vertical angle between the horizontal line at eye level and the top of the image to minimize extended viewing neck strain. (Typically bottom of display image should be no lower than four feet AFF.) Refer to AVIXA’s V202.01:2016 Standard for Display Image Size for 2D Content. 

12. Image size must be based on the Basic Decision Making model in AVIXA’s V202.01:2016 standard with compensation made for ceiling heights by introducing additional displays to ensure minimum visual strain to students. Use of older rule-of-thumb guidelines must not be used, such as the 4-6-8 rule. 

13. The closest student seats to the presentation display screen should be based on Basic Decision Making (BDM) model in AVIXA’s V202.01:2016 standard with compensation and allowance made for CSU or Cal Poly Scheduling seating density requirements.

14. Student’s ability to access power for mobile devices should be incorporated into classroom designs.  Typically place electrical outlets around the classroom perimeter every 5 feet or as necessary to allow for 30% utilization.  All outlets must be within ADA guidelines for reach (i.e. 18" AFF).

15. Classroom lighting should be recessed for rooms with a drop tile ceiling and not incorporate any hanging fixtures. 

16. Classroom lighting should be grouped into lighting zones with controls near the instructor area that allow the instructor to turn on/off lighting within the zones. 

17. Classroom lighting systems must provide an interface and API to connect to the classroom AV control system   

18. Classroom lighting scenes and presets based on zones must be created, and that type of information must be documented as part of the classroom configuration documentation 

19. Classrooms specifically designated for distance learning must follow IES/AVIXA RP-38-17 video conferencing lighting standard  

20. If there are wall-mounted projectable whiteboards, the same wall should have a dark color to improve the contrast of the projected image.  If it is used in a distance learning scenario with a remote presenter, the wall behind the students should also be a neutral to darker color.

21. Learning spaces should be free of any structural elements (posts, beams, pillars, hanging lights, walls, room angles, etc…) that hinder the sightlines of students. 

22. Learning spaces should incorporate generous amounts of usable whiteboard surfaces.  A minimum of 10’ of linear whiteboard space on the same horizontal plane should be available for usage while projected images are in use.   

23. Audio–Visual system design and components shall be approved by a Cal Poly ITS Operations representative, typically the Classroom AV engineer; incorporating approved “standard” equipment elements, incorporate robust wireless networking, sufficient to incorporate the increasing demand of mobile. 

24. If a Classroom Audio-Visual system must be designed in a way that does not meet the current Cal Poly ITS Classroom standard, the reason for the deviation must be clearly documented and must receive ITS approval before any purchases are made.   

25. Audio–Visual Contractor submittals shall include: Parts list, shop drawings including rack layout diagrams, cable lists, and line-diagrams, post-project as-built drawings, equipment specification sheets, and warranty information.  

26. All Audio–Visual cables and connections shall be labeled at both ends of the cable following the AVIXA F501.01:2015 standard.  Cal Poly utilizes two lines for cable labels, a Cable ID, and a Cable source to destination description. 

27. Classroom design should seek to incorporate energy-saving “green” audiovisual features based on AVIXA’s ANSI 4:2012 Audiovisual Systems Energy management standard as well as “green” cradle-to-cradle construction elements.  

28. Classroom design must follow environmental guidelines for lighting levels; ambient noise levels—both HVAC and ingress; acoustic treatment. Refer to the section below: Acoustics and Environment. 

29. When planning for AV in new buildings, especially ones that include university scheduled classrooms, an Architect and AV consultant must coordinate with the ITS standards document and AV designer and include ITS in all early budgetary discussions, programming phase charrettes and planning, and post-programming drawing reviews of construction drawing sets. 

30. Final Audio-Visual equipment selection and system design shall be coordinated with campus representatives.  Due to the rapidly changing technology horizon; standardized equipment and system design selections should be made as close to building commissioning as possible to ensure the most up-to-date technology is available.   

31.  It is required to acoustically treat rooms to optimize STI (sound transmission index) to prevent transmission of both the vocal frequency range between rooms and low frequencies). New build out of classrooms requires walls built up to the deck, staggered studs between gypsum boards, and acoustic sound batting between gypsum board.  Rubber baseboard molding needs to be acoustically rated along with any glue used. Ceiling tiles must be acoustically rated as well, and we recommend  the use of reclaimed denim insulation  to improve  noise reduction coefficient rating.   

32. Any conflicting standards presented, the more stringent standard must be used or referred to the AHJ (authority-having-jurisdiction)

Loudspeakers  

A number of variables determine how many ceiling speakers are required for proper coverage in a given application. Each environment is different based on the room dimensions and ambient noise. Consideration must be given to the listener height, audio program content, desired SPL - sound pressure level, and how much the client will tolerate sound pressure level variances throughout the space. Since speakers are often tailored for specific applications, their design and performance play a major role in determining quantities and positioning. Refer to Appendix below for essential loudspeaker formulas.
