CHAPTER
7 : Building Systems
INTRODUCTION
Purpose
The intent of Chapter 7 is to provide standards and guidelines
necessary to plan, design and construct school facilities throughout the state
of Arkansas. The focus is on building systems and materials that will provide
buildings that are economical and reflect quality construction, along with
mandatory performance standards, additional options and available choices. All
items and systems, such as loose furnishings, casework, technology, etc.,
should be integrated early in the planning phase of the project.
Definitions
The planning and design of school facilities shall be based upon
criteria described in Chapter 7 in accordance with the following
definitions:
"Standards" - Performance or construction required items for
which there is mandatory adherence.
"Guidelines" - Performance or construction items which are recommended,
but NOT required.
"Examples" - Typical component(s) of standards or guidelines.
Codes and Standards
Applicable local, state, and international building codes and standards
are not repeated in this chapter. It is the responsibility of the Design
Professionals to conform to the current codes in their design process. Should
the standards contained in this manual be in conflict with international,
state, or local codes, the established codes shall prevail. The requirements of
ADAAG (Americans with Disabilities Act) should be consulted.
No attempt has been made to provide detailed specifications in Chapter
7. Standards and guidelines are available that allow architects and engineers
the flexibility to design to fit the school district needs.
Applicability
The construction and performance standards and guidelines contained
herein are applicable to both new construction of public school facilities and
renovation of existing public school facilities. Every attempt should be made
to apply these standards and guidelines to existing buildings, in gradual steps
as funding and other influences allow. (refer to Chapter 1 It may be recognized
that some standards may not be compatible with existing facilities in
renovation projects nor may it be possible to completely conform a performance
or construction standard to new a new facility. It those instances variances to
those standards, upon request, may be granted by the Division.
Green Building Design (optional)
A strong motive of these building systems standards and guidelines is
to promote high performance schools. High performance schools are healthy,
comfortable, energy efficient, resource efficient, water efficient, safe,
secure, adaptable, and easy to operate and maintain. Designing for high
performance goals is a guideline. It is to be considered, but not
mandatory.
Commissioning (optional)
The commissioning process is a single-point responsibility to make sure
that certain systems in a building are functioning and performing according to
the design intent. The independent Commissioning Agent goes far beyond the
occasional Design Professional job visits during the construction period.
Actual tests are performed and components are verified under the guidance of
the Commissioning Agent. Several systems can be commissioned, but emphasis in
the chapter is to commission the HVAC components.
Definition
Commissioning is the process of ensuring that systems are designed,
installed, functionally tested, and capable of being operated and maintained
according to the Owner's operational needs.
Application
Commissioning may be applicable to both new facilities and renovation.
It is a guideline to be considered, but not mandatory.
Commissioning Authority (CA)
The CA is in charge of the commissioning process and is an objective,
independent advocate of the Owner.
Commissioning Authority Options
CA can be selected from an independent third party; a mechanical or
installing contractor; or a design professional.
Contractor: Desirable when building is small and contractor performs
all mechanical work, but a conflict of interest can arise.
Design Professional: Good idea provided that the project specifications
detail the requirements. Already familiar with the design intent but may not
have day-to-day experience in the process.
How To Select
Use competitive Request for Qualifications (RFQ) and follow a
qualification based selection process (QBS).
CA Qualifications
Experience required:
* Designing, specifying, or installing educational building mechanical
control systems or general HVAC systems
* Working with project teams and conducting "scoping meetings"
* Building systems start-up, balancing, testing, and
troubleshooting
* Commissioning at least two projects involving HVAC and lighting
controls
* Writing functional performance-test plans for at least two
projects.
Extent of Commissioning
The degree or extent of commissioning for new buildings is recommended
for the planning, design, and construction phases. However, involvement can
occur only in design, construction, or post-construction phases.
What to Commission
All projects that include controls, EMCS, pneumatic equipment,
integrated systems, HVAC-related equipment, and air distribution systems should
be commissioned.
Benefits
* Improved performance of building equipment and building systems
interactions
* Improved IAQ occupant comfort and productivity

IAQ
* Reduced operation and maintenance costs
* Maximize energy efficiency
* Provide training for school personnel
Green Building Design (optional)
The term "green building" is synonymous with "high-performance
building", "sustainable design and construction", as well as other terms that
refer to a holistic approach to design and construction. Green building design
strives to balance environmental responsibility, resource efficiency, occupant
comfort and well-being, and community sensitivity. Green building design
includes all players in an integrated development process, from the design team
(building owners, architects, engineers, and consultants), to the construction
team (materials manufacturers, contractors, and waste haulers), to the
maintenance staff and building occupants. The green building process results in
a high-quality product that maximizes the owner's return on investment.
Why Design Green?
The building sector has a tremendous impact on the environment.
According to the U.S. Department of Energy (DOE), buildings in the United
States consume more than 30% of our total energy and 60% of our electricity
annually. Buildings are a major source of pollutants that cause urban air
quality problems and contribute to climate change. Buildings produce 35 % of
the country's carbon dioxide emissions. Green building practices can
substantially reduce the negative environmental impacts associated with these
buildings and reverse the trend of unsustainable construction activities. Green
design also reduces operating costs, enhances building marketability,
potentially increases occupant productivity, and helps create a sustainable
community. Green design has environmental, economic, and social elements that
benefit all stakeholders, including owners, occupants, and the general
public.
Creating High Performance Schools
(optional)
School districts around the country are finding that smart energy
choices can help them save money and provide healthier, more effective learning
environments. By incorporating energy improvements into their construction or
renovation plans, school can significantly reduce energy consumption and costs.
These savings can then be redirected to educational needs such as additional
teachers, instructional materials, or new computers.
Establishing High Performance Goals
Cost-effective energy- and resource-efficient schools start with good
planning. Working closely with the school's design and planning staff, the
architects and engineers should develop objectives that reflect local
conditions and priorities, balance short-term needs and long-term savings, and
address environmental issues. Goals can include reducing operating costs;
designing building that teach; improving academic performance; protecting the
environment; increasing health, safety, and comfort; supporting community
values; and considering emerging solutions.
A. Reducing Operating Costs - To ensure that
your school is water- and energy-efficient, you must first work with the school
system to establish clear consumption goals. Given your climatic region and
building type, this "energy budget" must be realistic, and it must be based on
the potential of current, proven energy-saving technologies. Many energy-and
resource-saving options have very good financial value. Some of these solutions
do not add anything to installation costs.
B. Designing Buildings That Teach - When
designing the school, consider the importance of incorporating high performance
features that can be used for educational purposes. Some high performance
features may be harder to rationalize financially, but from an educational
standpoint are still important to consider. Solar electric systems
(photovoltaics), for example, may have a longer return on investment, but if
installed properly, can be a very powerful educational tool.
C. Improving Academic Performance - During
the past decade, remarkable studies have indicated a correlation between the
way schools are designed and student performances. You can maximize student
performance by setting air quality objectives that:
1. Define a level of indoor air quality
desired during occupied times
2.
Place limitations on the use of materials, products, or systems that create
indoor air quality problems.
3.
Require monitoring equipment.
Establishing day lighting objectives will also improve classroom
conditions and can help improve performance if you:
1. Include controlled day lighting in all
classrooms, administrative areas, the gymnasium, and other significantly
occupied spaces.
2. Develop
intentional visual connections between the indoor and outdoor
environment.
D.
Protecting Our Environment - High performance school design takes into
consideration not only the economic and academic impacts of design, but also
environmental impacts. Environmentally sound design elements are those that:
1. Use renewable energy systems and
energy-efficient technologies
2.
Incorporate resource-efficient building products and systems
3. Promote water-conserving
strategies
4. Use less polluting
transportation alternatives
5.
Establish recycling systems
6.
Incorporate environmentally sound site design
E. Designing for Health, Safety, and Comfort
- You cannot design a high performance school without including design
strategies that address health, safety, and comfort issues. Goals should
include objectives that:
1. Implement day
lighting and indoor air quality solutions to make the school a healthier place
to teach and learn
2. Address
acoustical and thermal comfort
F. Supporting Community Values
1. Incorporating high performance strategies
in your school's design results in a win-win situation for the community and
the school. Through the implementation of energy-savings strategies, the school
saves money and taxpayers benefit. Additionally, the energy dollars saved don't
leave the immediate region but stay within the community and help to build a
stronger local economy. Building to high performance standards implies the
purchase of locally manufactured products and the use of local services. This
approach is effective because much of the environmental impact associated with
materials, products, and equipment purchased for construction involves
transportation. The more transportation, the more pollution. Specifying local
products benefits the community in the same way that retaining energy dollars
helps: it strengthens the local economy.
Green Building Rating System
(optional)
The Green Building Initiative design program called Green Globes and
the program offered by the U.S. Green Building council, LEED (Leadership in
Energy and Environmental Design), are green measurement systems designed for
rating commercial and institutional buildings. Both address new construction
and major renovations. The programs address various environmental categories,
typically sustainable sites, water efficiency, energy, indoor environmental
quality, and materials and resources. Both are performance oriented systems
where points are earned for satisfying performance criteria. Different levels
of green building certification are awarded based on the total points
earned.
A.
Sustainable Sites - Properly chosen and developed site help minimize negative
project impacts of the surrounding areas, the project site, and occupants of
the project site.
B. Water
Efficiency - Reduce quality of water needed for the building and the burden of
water from the site on municipal treatment facilities.
C. Energy & Atmosphere - Establish energy
efficiency to reduce operational expenses, conserve natural resources, and
reduce local and global pollution.
1.
Commissioning and Training - All schools should be commissioned to ensure that
the design meets the expectations of the district, and that the school is built
as it was designed. Modern schools are complex buildings. Commissioning ensures
that all building systems are working properly, and that the school staff knows
how to operate and maintain them.
D. Materials & Resources - Reduce the
amount of materials needed. Those used should have less environmental impact.
More sustainable alternatives exist and should be used as much as possible.
Waste from the project should be reduced and managed. It is now possible to
recycle, compost, or salvage a majority of construction and demolition waste
instead of disposing it in landfills.
E. Indoor Air Quality - Schools must protect
student health, and good indoor air quality is essential for healthy schools.
Good indoor environmental quality can be managed by controlling the sources of
pollutants, ensuring thermal comfort and student connections to the outdoor
environment.
1. Acoustics - If not controlled
to appropriate levels, noise from loud ventilation systems, outdoor sources,
and neighboring rooms can significantly impeded communication between teachers
and students. Young learners, students with hearing difficulties, and those
learning English as a second language are particularly vulnerable. Classrooms
should be designed to be accessible for all students.

General Guidelines
1. This
section establishes the minimum design requirements that must be met by the
Plumbing Design Professional. Minimum code requirements are the current edition
of the Arkansas State Plumbing and Gas Codes. Local codes and standards may
take precedence over these requirements provided said codes and standards are
considered more stringent.
2. All
systems shall be designed in compliance with the current Arkansas Energy
Code.
Site Design Parameters Guidelines
1. Determination of the available site
services with regard to gas service, sanitary systems, storm water systems,
domestic water system, and fire service system is necessary as a part of the
site selection process.
2. The
building plumbing system design is to be complete to 5 feet outside the
perimeter of the building foundation system and shall include all piping,
fixtures, appurtenances, and appliances in connection with a supply of water
(except for fire sprinkler systems), sanitary drainage or storm drainage
facilities within or adjacent to any building, structure, or conveyance on the
premises. The connection to a utility water meter or other public water or
sewer utility property or other source of water supply or sewage disposal and
storm water structures shall be designed by the Site Utility Design
Professional from 5 feet outside the perimeter of the building foundation
system. Food service grease interceptors, science room acid neutralizing sumps,
and gas piping and regulators, shall be designed, in most cases, by the
Plumbing Design Professional.
3.
The Plumbing Design Professional is required to evaluate the need and method to
provide gas service to the building. All natural gas piping systems shall be
installed in accordance with the Arkansas Gas Code. If natural gas service is
not available, the installation of liquid propane gas should be investigated.
The estimated gas loads for operation of the heating water boilers, domestic
water heaters, food service equipment, science program usage, and miscellaneous
items are obtained from the appropriate disciplines by the Plumbing Design
Professional and totaled with the inclusion of a growth or safety factor.
Discussion with the local gas company is necessary, both to determine potential
service costs and to determine the responsibilities of the building owner and
the gas company regarding installation. It is also important to determine the
gas pressure requirements for the equipment in the building and communicate
this need to the gas company. The Plumbing Design Professional or Site Utility
Design Professional shall design the gas service.
Valving Standards
1.
Valves will be installed to isolate
individual plumbing fixtures and groups of plumbing fixtures to permit shut
down of the fixture or equipment item without affecting the remainder of the
building.
2.
The
domestic water system valves shall be bronze construction gate valves or valves
with a ball-type conventional port.
3.
The gas supply to science rooms and
art rooms shall have an emergency solenoid-type, automatic shutoff valve with a
manual reset. The purpose of the valve is for shut down of the gas in case of
an emergency or when the fire alarm system is activated. A solenoid-type,
automatic shutoff valve with a manual reset shall be installed to shut the gas
off to the appliances under the kitchen hood in the event there is a fire under
the hood. The valves are designed normally closed and are held open by an
electric solenoid valve. A mushroom-type wall switch shall be located in the
room for solenoid activation.
Hangers Standards
1.
Provide hangers for all horizontal,
suspended, domestic, water, gas, sanitary, and storm piping with distances as
noted in the state and local codes.
Identification Guidelines
1.
Piping shall be identified in mechanical rooms, unfinished spaces without
ceilings, above suspended lay-in acoustical ceilings, and crawl spaces for the
type of service and direction of flow. Equipment shall be identified with
nameplates.
Testing Guidelines
1. Domestic
water, storm and sanitary sewers, and gas piping shall be tested per state and
local codes.
Potable Water System Standards
1.
All buildings shall include a
potable domestic water system serving all sinks, toilets, showers, food
service, custodial needs, hose bibs, HVAC plant systems, and drinking water
coolers/fountains. All municipal domestic water entering the building must pass
through a reduced pressure backflow preventer to protect the outside water
source from contamination in the building. Whenever possible, the backflow
device shall be located inside the building. A main pressure-reducing valve is
required if the incoming water pressure exceeds 75 psi. All backflow prevention
devices shall be installed and maintained in accordance with the requirements
of the Arkansas Department of Health and/or the municipal water
purveyor.
2.
Water
distribution throughout the facility will be through piping systems located
above ceiling areas and below insulation. Piping installed under slab areas
shall be avoided where possible, unless accessible for maintenance on the
system.
3.
Domestic
water systems within the building shall be Type K or L copper tubing. The use
of polyvinyl chloride, chlorinated polyvinyl chloride, or polybutylene material
will not be permitted.
4.
Water piping and gas piping to island sinks shall be in an accessible
trench in the floor with a removable cover.
5.
The required pressure for operation
of the furthest fixture from the incoming service will determine if a pressure
booster system will be required. The booster system should be a packaged unit
that includes all controls. Provide a constant-speed duplex pump package with
bladder-type compression tank to meet the flow requirements. It will be
necessary to consider the installation of an emergency power system in order to
maintain the operation of the booster system in the event of power outages, if
the building is to be used during emergency-type occupancies. Coordination with
the Electrical Design Professional will be necessary.
6.
Insulate the piping to minimum
requirements of current Arkansas Energy Code.
Domestic Water Heater System Standards
1.
A hot water return system with a
re-circulating pump shall be required if the building hot water piping is more
than 100 feet in length.
2.
The on/off operation of the 120 and 140 degrees Fahrenheit water
circulation pumps shall be controlled by time clock operation and an
aquastat.
3.
Instantaneous water heaters with a storage tank shall be required for high use
applications in buildings with kitchens and/or shower room facilities.
Tank-type water heaters shall be considered for use in elementary school
applications having no dishwasher facilities and no locker

whenever economically feasible. Consider using the savings from the
centralization of the systems to offset the cost of the inter-building,
fiber-optic cabling.
Wiring Standards
A.
Media Standards
1.
Unshielded twisted pair
a.
The minimum standard for horizontal
distribution wiring is six (6) cables of category 5e or higher, 4-pair,
24-gauge unshielded twisted pair (UTP) wiring, terminated in each classroom.
The standard specifies 100-ohms impedance at one (1) megahertz, satisfying
Integrated Services Digital Network (ISDN) and Institute of Electrical and
Electronics Engineers (IEEE) 802.3 10BaseT requirements.
b.
Note: wiring specifications
are a minimum of category 5e. When bandwidth is expected to be above category
5e of 1 Gigabit per second (Gb/s or 100 Mhz) then category 6 for up to 10
Gigabit or 200+ Mhz should be used. From a future proofing perspective,
it is always better to install the best cabling available. This is because it
is so difficult to replace cabling inside walls, in ducts under floors and
other difficult places to access. The rationale is that cabling will last at
least 10 years and will support at least four to five generations of equipment
during that time. If future equipment running at much higher data rates
requires better cabling, it will be very expensive to pull out category 5e
cabling at a later time to install category 6 cabling.
2.
Fiber optics
a.
The media standard for both intra-
and inter-building backbones is 62.5/125 micron graded-index multimode optical
fiber cable. A minimum of six-fiber strand cable should be installed for each
cable run.
Telecommunication Room Wiring Guidelines
1. A telecommunication room (TR) is a local
communications equipment room. This should be dedicated space providing a
secure environment for the installation and termination of cable network
electronics and other telecommunications equipment, as specified in the
ADE IT Security Policy (ITSP), 2B2.
2. The main cross-connect (MC), the point
where the backbones and horizontal distribution facilities intersect, should be
located near the center of the area served, preferably in the building core
area. Every effort should be made to secure as large an area as possible. When
one MC is insufficient to cover a building, additional TRs must be established.
The same parameters apply for both TRs and MCs.
3. Locate telecommunication rooms
away from any sources of electromagnetic interference, such as
electrical power-supply transformers, motors, and generators. There should be
no water sources in this area.
4. There should be one telecommunications
room for each 20,000 square feet zone/wing/building section. The recommended
minimum closet size is 6 feet by 6 feet. The recommended minimum ceiling height
is 8 feet, 6 inches. Closets should be designed with adequate conduit or
openings through beams and other obstructions into the accessible ceiling
space. Closets should be designed with controls to limit access to authorized
personnel only, as specified in the ADE IT Security Policy (ITSP),
2B2.
5. The MC contains
wiring terminations and communications equipment to serve a building. This
equipment may include modular fiber distribution panels, wiring termination
panels, telephone systems, concentrators/hubs that connect communication lines,
routers that connect users on different networks, CATV (cable television)
equipment, and equipment racks.

to building; however, a minimum number of doors should be selected for access
control devices. All other exterior doors should be equipped with fire panic
devices to prevent entry while allowing exit. The system shall have a battery
backup (UPS system) for power of at least 4 hours. Provide SNMP management on
UPS system and connect to network. Provide for graceful shutdown of equipment.
The controller shall be IP-connected to the network and shall permit viewing
and control over the network, via PCs. Connect the central power supplies to
building emergency power, when available.
2. Card readers should be proximity or
biometric readers. Doors protected by access control will open for exit by
using a crash bar release. Each of these doors will be monitored via the door
alarm contact for being propped or stuck open. In an emergency, the protected
doors can be seized allowing exit only.
3. The system will be on a programmed
schedule that automatically unlocks the doors for admittance at the start of
the day, locks doors (except the main entrance) during class hours, and locks
all doors at the close of the day. This will funnel visitors to the front door
where they can be observed and controlled.
4. The head-end equipment for the access
control system will, ideally, integrate both alarm and video signals.
Consideration shall be given to integrating the system on a district-wide basis
via the wide area network.
Interactive Classroom Design Guidelines
(optional)
Videoconferencing classrooms require special attention to ensure that
the highest quality sound and visual signals are transmitted and received by
participants. The following are recommendations on the building of interactive
videoconferencing rooms.
A. Location: A
quiet, convenient and central location is best. It should be isolated or
separated from the sources of loud outside noise. This minimizes the need for
sound isolation treatment. The room should be near an area that allows for
direct and indirect supervision of the class (for monitoring students, security
and liability reasons). Access should be suitable for a person with a physical
disability. A ground floor location is preferable. Areas to avoid are those
that are located near high traffic areas, lifts, plumbing, workshops, and plant
rooms. Care should be taken to diminish the sounds from the air conditioning
ducts, the gymnasium, band room, shop, or cafeteria.
B. Classroom Size: Classroom size depends on
the maximum number of participants you hope to have in your room. We suggest
planning for a minimum of 20 participants, but ideally be prepared to
accommodate at least 25, with tables and chairs. The space should be
approximately 24 feet wide by 30 feet long, with a ceiling of 9 feet minimum,
to accommodate compressed interactive equipment along with 20 students, or a
majority of the faculty for staff development. For teaching seminar groups
involving 100 or more, the system should be placed in a lecture theatre
setting. Consideration shall be given for appropriate acoustics.
C. Classroom Shape: To reduce acoustic
effects, square rooms should be avoided, if possible. An oblong or irregular
shaped room is a better shape, as it does not encourage standing waves (and
thus echoes).
D. Physical Layout:
Room layout will depend on the number of participants, the available space and
the purpose of the room. Layout is a compromise between clear audio, the best
viewing of monitors, interaction, and the space available.
E. Acoustics: Audio quality is one of the
most critical technical elements in a successful videoconference, and it has
implications for the selection and placing of the room, as well as for its
construction and treatment. The participants and presenters must hear each
other clearly, both locally and remotely, without strain. Some factors
influence the quality of the sound in a videoconference; namely, ambient noise,
room acoustics and reverberation, and equipment configuration.
1. Acoustic treatment of rooms will need to
be executed with materials that satisfy the relevant building regulations, so
it is essential that this work be supervised by qualified staff.
2. The internal acoustics of a room are very
important. Too much reverberation (echoes in a closed room) will present
problems. Rooms should not be too absorbent, as this will present an unnatural
and uncomfortable environment for the participants. A room that suffers badly
from echoes should have the acoustic treatment applied to the adjacent walls
rather than the two opposite ones. This will allow standing waves to be reduced
in two dimensions (lengthwise and widthwise).
3. Hard blank walls can be deadened by heavy
curtains, which have the added bonus of improving the décor. Carpets and
other soft furnishings will improve the acoustics and will generally be more
cost-effective than acoustic ceiling tile.
F. Windows: The ideal room has NO windows.
Windows always cause problems for television cameras due to the changing light
levels. Window Treatments: If windows are unavoidable, heavy curtains or drapes
should be applied to improve acoustics.
G. Entrances: Entrance at rear
of the room is the best option. Access should be suitable for a person with a
physical disability.
H. Flooring:
There should be carpet on the floor. Carpets and other soft furnishings will
improve the acoustics and will generally be more cost-effective than acoustic
ceiling tile.
I. Lighting:
Fluorescent lighting is the most realistic choice for these rooms. Normal
office lighting levels will be adequate, i.e., 500 Lux, and an intermediate or
warm fluorescent tube color (equivalent color temperature 3200-4000 Kelvin).
There should not be a buzzing sound projected from the lights in the classroom.
1. Install lighting at the front of the room
but ensure that it is on a separate switch from the rest of the room lights. As
a general practice, it is advised that classroom lighting, even in traditional
classrooms, be "zoned" into rows of separately switched lights. These rows
should run across the width of the room, not down its length. In this way the
front of a room, beside the projection screen, can be darkened to give better
contrast to the projected images, but still retain a good level of light over
the participant's desks
.1.2
Recommend using high efficiency T-8 lamps and electronic ballast along with the
use of occupancy light sensors to prevent energy waste in unoccupied areas
and/or buildings, along with copy/work rooms, rest rooms,
etc.
J. HVAC:
The HVAC should be seen - not heard in the classroom. Microphones are sensitive
to moving air. The microphone amplifies normal air conditioning and can cause a
large amount of background noise in a videoconference. Air
conditioning/handling equipment will also require installation by experienced
staff to ensure the quality of air is adequate and the temperature, humidity,
etc. are of an acceptable standard.
K. Communication: There should be a dedicated
phone line and phone in the videoconference room. It is also recommended that
there be a FAX line in the room. It is suggested that you have at least one
phone and an additional phone line, or jack, in the room for a FAX line or
expansion in the future.
L.
Computer: Videoconference rooms should have a minimum of four areas to access a
computer and the Internet.
M.
Electrical: Electrical installations need to comply with current National
Electrical Code (NEC) wiring regulations and should be carried out by competent
and qualified staff. The equipment used for videoconferencing should be powered
from a clean main supply to avoid electrical interference. It should not be on
a circuit that is shared by large electrical loads such as plant motors, lifts,
workshops, etc.
N. Wiring: To
minimize hum pickup, signal cables (i.e. sound and vision) should not be run
parallel to main supply cables; this is especially important for microphone
cables. Also, do not run over or parallel to lighting ballasts.
1. Several cables should be run from the
control desk to the picture monitors and loudspeaker/audio mixer and also to
the CODEC, wherever these are situated. Some provision must be made for small
ducting or conduit to protect these cables.
2. When cable runs across floor spaces cannot
be avoided, some form of protection must be provided. Special rubber cable
protectors are available that protect the cables and minimize the risk of
tripping.
O. Room Color:
Generally high contrast color is desired. Light Blue or light gray is commonly
used. Stay away from dark and vivid colors. One recommendation is Periwinkle
Blue, or Slate Gray.
P. Furniture
: Individual sites will have their own preferences for the type of
furniture to be installed. Try to avoid bright, reflective surfaces that may
cause unwanted highlights in the picture and distract the viewer from the main
subject matter.
