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

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 times2. 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 technologies2. Incorporate resource-efficient building products and systems3. Promote water-conserving strategies4. Use less polluting transportation alternatives5. Establish recycling systems6. Incorporate environmentally sound site designE. 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 learn2. Address acoustical and thermal comfortF. 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.Application
Green building design may be applicable to both new facilities and renovation. It is a guideline to be considered, but not mandatory.

A Technology System Plan and Specifications shall be prepared as part of the overall building design process before construction begins in accordance with the latest edition of the Building Industry Consulting Service International (BICSI) Telecommunications Distribution Methods Manual (TDMM). It shall be designed and approved by a Registered Communications Distribution Designer (RCDD).B. All work shall be performed in accordance with the latest revisions of the following standards and codes:4. National Electrical Code5. EIA/TIA-568 Commercial Building Wiring Standards6. EIA/TIA-569 Commercial Building Standard for Telecommunication Pathways and Spaces7. EIA/TIA J-STD-607-A Commercial Building Grounding/Bonding Requirements StandardC. A Technology System Plan shall consist of the following minimum Telecommunications Drawings, as required: 1. Campus or Site Plans, Exterior Pathways, and Inter-Building Backbonesa. Shows physical and logical connections from the perspective of an entire campus - such as actual building locations, exterior pathways, inter-building backbone cabling on plan view drawings, and major system nodes and related connections on the logical system drawings.2. Layout of complete building per floor - Serving Zone Boundaries, Backbone Systems, and Horizontal Pathways. a. The drawings should show the complete building layout per floor and indicate location of serving zones, communication equipment rooms, access points, pathways, and other systems that need to be viewed from the complete building perspective.3. Serving Zone Drawings - Drop Locations and Cable IDsa. The building is divided up by its serving zones. Drawings to indicate drop locations, communication equipment rooms, access points and detail callouts for communication equipment rooms and other congested areas.
4. Communication Equipment Rooms - Plan Views - Tech and AMEP/Elevations - Racks and Wall Elevation a. Detailed look at communication equipment room. Drawings should indicate technology layout (racks, ladderacks, etc.), mechanical/ electrical layout, rack elevation, and backboard elevation.
D. The Technology Design shall include the following components: 1. Mandatory Systems b. Video distribution systemc. Data / computer network systemd. Central sound / public address systeme. Gymnasium sound reinforcement systemf. High school student dining sound reinforcement systemg. Student dining sound reinforcement systemh. Music room sound reinforcement systemE. The Technology Designer should endeavor to reduce the quantity of Main Cross-Connect Rooms (MCs) by centralizing the MCs and/or using one MC to serve multiple floors or areas. For example, in a 3-story building, place the MC on the second floor and serve the 1st, 2nd, and 3rd floors from the same closet. The Technology Designer shall coordinate the quantity and size of MCs required with the Design Professional.F. The Technology Designer should endeavor to centralize as many Technology and Control Systems as possible for the district into one school building or Network Operations Center (NOC), and interconnect the buildings and systems via fiber-optic cables 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 Standards1.Unshielded twisted paira.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 opticsa.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.Telecommunication Room Wiring Standards: Interior Environment

Exterior camera housings shall be grounded in accordance with NEC and EIA/TIA-607.8. Monitors: Systems with 4 or fewer cameras will be monitored with a 13-inch (minimum) color monitor. Systems of 5 cameras or more will be monitored with 20-inch color monitors. An additional 20-inch (minimum) color monitor should be mounted on the ceiling at the public entrance to show that cameras are being used in the public areas.9. Consideration shall be given to integrating the system on district-wide basis via the wide area network.F. Minimum Standard: Access Control Systems1. All access control systems should be a minimum of Windows 2000 based or compatible. The system should have the ability to integrate alarms and video signals into one centralized system. The number of doors on the System will vary from building 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.ARKANSAS SCHOOL FACILITY MANUAL PROGRAM OF REQUIREMENTS (POR) SUMMARY AND REQUIRED SPACES
