    Study Notes

    Reach and Doorway Requirements

    • Maximum reach height is 48 inches for depths up to 10 inches
    • Maximum reach height is 46 inches for depths between 10 inches and 24 inches
    • Minimum door opening width is 32 inches

    Door Hardware

    • Maximum force required for pushing or pulling interior doors and gates is 5 pounds
    • Maximum force required for pushing or pulling sliding or folding doors is 5 pounds

    Ramps

    • Maximum slope for ramp runs is 1:12 (1 inch rise for every 12 inches of run)
    • Maximum cross slope for ramp runs is 1:48
    • Minimum clear width for ramp runs is 36 inches
    • Maximum length of a ramp run without a landing is 30 feet
    • Maximum rise for any ramp run is 30 inches
    • Ramps must have landings at the top and bottom of each run
    • Landings must comply with section 405.7

    Handrails

    • Handrails must be continuous within the full length of each stair flight and ramp run
    • Inside handrails on switchback or dogleg stairs and ramps must be continuous between flights or runs
    • Handrails on ramps in assembly areas are not required to be continuous in aisles serving seating

    HVAC Systems

    • Heating is the technology of indoor environmental comfort
    • Ventilation is the process of exchanging air between the outdoors and a conditioned space to dilute contaminants and improve air quality
    • Air conditioning is the process of controlling temperature, humidity, and air circulation to provide comfort

    Human Comfort

    • Thermal comfort standards aim to satisfy 80% of occupants
    • ASHRAE 55 is the Standard for Thermal Comfort
    • Thermal Comfort is influenced by temperature, humidity, air quality, acoustics, lighting, physical aspects, and psychosocial situations

    Thermal and Humidity Control

    • Temperature standards for thermal comfort are 75 degrees Fahrenheit with 50% relative humidity
    • Lower temperatures are tolerable with slightly elevated humidity

    Air Distribution

    • Dampers regulate airflow
    • Balancing dampers regulate airflow into a space
    • Fire dampers close ducts to prevent fires from transferring through ductwork
    • Smoke dampers close ductwork to prevent smoke from being distributed throughout a building

    Air Distribution Sizing

    • Factors that impact overall duct sizing include occupant load, room use, building use, exterior envelope, lighting, equipment, and outdoor conditions

    Building Code Ventilation

    • Ventilation systems must be designed to supply the minimum outdoor airflow rate
    • Ventilation rates are based on occupancy classifications, occupancy density, and airflow rates
    • Ventilation systems must supply the required rate of ventilation air continuously during building occupancy
    • Smoking lounges are an exception, and must have ventilation exceeding code requirements

    CFM and ACH

    • Cubic Feet per Minute (CFM) is the amount of air volume moving through ductwork
    • Air Changes Per Hour (ACH) is the number of times the air within a space is changed per hour

    Air Distribution Ductwork

    • Ductwork size is determined by air velocity, pressure, and volume
    • Ductwork clearance is the duct size plus 2 inches for insulation
    • The last branch of ductwork should be 4 feet from the end of the main duct
    • Maximum length of flexible ductwork is 6 feet
    • Maximum height of ductwork is the distance from the bottom of a structure to the bottom of a finished ceiling minus 6 to 12 inches
