April 30, 2023 Update of the New ICC Code, Standard and Guideline Process

Minimum Design Loads and Associated Criteria for Buildings and Other Structures



Updated: September 13

(Original Post: April 12, 2021)

 

During today’s colloquium we will review all of the concepts tracking in the Group A tranche relevant to student housing facilities owned by the college, university or school district; soon to be discussed during the Committee Action Hearings starting September 22nd.   There are quite a few so we will likely not have time to cover best practice titles for off-campus housing; a sensitive area.  We will set a separate colloquium for this topic in early 2022.

Group A Committee Action Hearings begin September 22nd and we will provide a link to the ICC livestream every day.

During today’s colloquium on fire safety we will review all of the concepts tracking in the Group A tranche; soon to be discussed during the Committee Action Hearings starting September 22nd.

 


July 12th

For today’s colloquium on elevators and lifts we will review the following concepts tracking in the Group A tranche:

IBC § 1109.2.1| E30-21, E31-21, et. al | The intent of this proposal(s) is to allow for ramps to serve as an accessible route off an occupied roof instead of requiring standby power on the elevator for that occupied roof.

IBC § 1109.2.1| E30-21, E31-21, et. al | Related to the above.  Parking garages and self-service storage facilities have extremely low occupancy loads. Increasing the 4-story limit to 6-
stories for when standby power for elevators is required takes this practical difference in uses into account.

IBC § 1109.2.2| E34-21, et. al | Providing the fire department the option for using the elevator for assisted evacuation in any elevator building using fire department recall; with the additional
improvements of standby power (1009.4.1) at five stories and the fire service access elevator protections at 120 feet.

IBC § 1010.2.15 | E56-21 | Elevator lobby exit access doors

IBC § 1010.2. | E56-21 | Elevator lobby exit access doors

IBC § 3006.3 |  G184-21 | Elevator hoistway pressure

IBC § 3001.2 |  G175-21 | Elevator communication systems

IBC § 1020.2.1 |  G182-21 | Elevator hoistway fire protection

IBC § 3007.6 |  G187-21 | Elevator corridors and access

Keep in mind that most of these failed as stand-alone proposals but will likely inform decisions on related proposals; at least administratively.

Social networks and culture in birds

October 25, 2024
[email protected]

No Comments

Birds are social creatures and many species have complex social networks. Social networks are defined as the patterns of social interactions between individuals within a population. Here are some things that are known about the social networks of birds:

  1. Flocking behavior: Many bird species form flocks, which are large groups of individuals that fly together and exhibit coordinated behavior. Flocking behavior is thought to help birds reduce the risk of predation, share information about food sources and mating opportunities, and maintain social connections with other birds.  §1202 of the International Building Code prohibits building envelope openings that encourage flocking behavior in attics, 
  2. Communication: Birds use a variety of vocal and visual cues to communicate with one another, such as calls, songs, displays, and body language. Communication plays an important role in establishing and maintaining social connections between individuals.
  3. Social hierarchies: Within bird flocks, there may be social hierarchies, where some individuals have more dominant positions than others. Dominant individuals may have access to better food sources, mating opportunities, and nesting sites.
  4. Mate choice: Many bird species choose mates based on social signals, such as displays, vocalizations, and courtship behavior. Mate choice can influence the structure of social networks within a population.
  5. Information sharing: Birds may share information about food sources and predator threats with one another. For example, some bird species engage in “public information use,” where they use the behavior of other individuals as a signal about the quality of a food source or the presence of predators.
  6. Family bonds: Some bird species form long-lasting family bonds, where parents and offspring remain together for extended periods of time. Family bonds can influence the social structure of bird populations and may contribute to the formation of social networks.

Overall, the social networks of birds are complex and dynamic, and play important roles in many aspects of bird behavior, including mating, foraging, and avoiding predators. Studying bird social networks can provide insights into the evolution of social behavior and the ecological factors that shape animal populations.  We examine the risks (and reward) of bird behavior on education community campuses.


Birds present several hazards to overhead electric and telecommunication circuits:

  • Electrocution: Birds that perch or nest on power lines or other electrical equipment can come into contact with live electrical wires and be electrocuted if their body presents a path to ground potential. 
  • Nesting: Birds may build nests on or near power lines or other electrical equipment, which can create a fire hazard if the nest materials come into contact with electrical components. Nests can also cause power outages if they interfere with the electrical flow or if birds build nests in inconvenient locations, such as on transformers or other important components.
  • Collisions: Birds may collide with power lines while in flight, which can cause injury or death to the birds and also damage power lines or equipment. In some cases, these collisions can also cause power outages or fires.
  • Droppings: Bird droppings can build up on power lines and electrical equipment, which can create a safety hazard if the droppings come into contact with electrical components. Droppings can also cause corrosion or damage to equipment over time.

Accordingly, the 2023 National Electrical Safety Code specifies minimum clearances between power lines and surrounding trees and vegetation to help prevent birds from coming into contact with the lines; requires the use of bird guards or other protective devices on power lines in areas where birds are likely to perch or nest and, where possible; removal of nests from power lines and equipment to prevent fire hazards and equipment damage.

Additionally, the U.S. Fish and Wildlife Service has developed guidelines for the protection of birds and other wildlife from power line hazards.  These guidelines provide recommendations for utilities on how to identify and manage potential bird hazards on power lines and equipment.  The International Electrotechnical Commission has developed similar standards

Flight is the most complex form of movement in the animal kingdom. Bird research has informed how humans design airplanes.  For example:

  • Wing design: Bird wings have evolved over millions of years to provide efficient lift and maneuverability. Researchers have studied the shape, size, and structure of bird wings to design airplane wings that are more efficient and fuel-efficient. For example, the shape of the wings of the Albatross inspired the design of the wings of the Boeing 777, which has one of the highest fuel efficiencies of any commercial aircraft.
  • Flight control: Researchers have studied how birds control their flight, particularly during takeoff and landing. This research has led to the development of technologies such as wing flaps, slats, and spoilers, which help airplanes achieve better control during takeoff and landing.
  • Aerodynamics: The study of bird flight has also helped researchers understand the complex physics of aerodynamics, such as airflow patterns, lift, drag, and turbulence. This understanding has led to the development of more advanced computer simulations and wind tunnel testing, which are used to design airplanes that are more aerodynamically efficient.
  • Materials: Birds have lightweight but strong bones and feathers, which have inspired researchers to develop new lightweight materials for use in airplane construction. For example, carbon fiber composites, which are used extensively in modern airplanes, were inspired by the lightweight but strong structure of bird bones.

"The little bird that doesn’t fly dies in the nest." (Toni Morrison, 'Song of Solomon')

There are standards and regulations for bird control in various industries and settings. These standards and regulations aim to prevent bird strikes, which can be dangerous for aircraft, and to manage bird populations that can cause damage or spread disease.  For example:

  • The Federal Aviation Administration in the United States requires airports to have a Wildlife Hazard Management Plan that includes bird control measures. This plan must address the potential for bird strikes and detail strategies for reducing the risk, such as habitat modification, bird scaring techniques, and lethal control methods in extreme cases.
  • In the agriculture industry, there are guidelines and regulations for bird control to prevent crop damage and protect public health. The US Environmental Protection Agency regulates the use of bird repellents and bird poisons to ensure that they are used safely and do not harm non-target species or the environment.  
  • There are also international standards for bird control in certain industries, such as the oil and gas industry, which has guidelines for managing bird populations that could be impacted by oil spills.

“A Girl Writing; The Pet Goldfinch” 1870 Henriette Browne

Bird control on college and university campuses should prioritize humane and non-lethal methods to manage bird populations and prevent bird-related hazards. Here are some best practices for bird control on college and university campuses:

  • Habitat modification: Modify the campus environment to make it less attractive to birds. This may involve removing or trimming trees and vegetation that provide food and shelter for birds, reducing open water sources, and using bird netting or barriers to block access to areas where birds may nest.
  • Education: Educate students, faculty, and staff about the importance of bird control and the negative impacts of feeding birds on campus. Encourage the campus community to report bird-related hazards, such as bird nests in building ventilation systems or bird droppings on walkways.
  • Non-lethal deterrents: Use non-lethal bird deterrents, such as visual scare devices, noise makers, and bird repellents, to discourage birds from congregating on campus. These methods are often effective in the short term but may need to be rotated or changed periodically to maintain their effectiveness.
  • Integrated pest management: Implement an integrated pest management (IPM) plan that includes bird control measures. IPM is a holistic approach that combines multiple strategies to manage pests, including birds, in an environmentally responsible and effective manner.
  • Monitoring and evaluation: Monitor the effectiveness of bird control measures on campus and evaluate their impact on bird populations and hazards. Adjust strategies as needed to ensure that they are effective and humane.

Overall, a comprehensive and humane approach to bird control on college and university campuses should prioritize prevention and management of bird hazards while minimizing negative impacts on bird populations and the environment.

2024 International Building Code Chapter 8: Interior Finishes 

When selecting colors for educational facilities, primary considerations are the following:  

Function and Purpose: The intended use and function of each space within the educational facility play a significant role in color selection. Different areas, such as classrooms, laboratories, common areas, or specialized rooms, may have distinct color needs based on their purpose. For example, calming and muted colors may be preferred in spaces where concentration is essential, while vibrant and stimulating colors could be used in collaborative or creative areas.

Age and Developmental Stage: The age group and developmental needs of the students using the facility influence color choices. Color psychology and research on the effects of color on learning and behavior can guide architects in selecting appropriate colors for different age ranges. For instance, soft, warm tones may be suitable for early childhood areas, while older students might benefit from a more sophisticated color palette.

Wayfinding and Orientation: Colors can be used strategically to aid wayfinding and create a sense of direction within the facility. Architects may choose different colors or color schemes for various zones or floors to help students and visitors navigate the space more easily. Clear and consistent color cues can enhance orientation and reduce confusion.

School Branding and Identity: Some educational institutions have specific branding colors or logos that they wish to incorporate into the facility design. Architects may work with the school administration or design team to integrate these brand elements appropriately, ensuring that the chosen colors align with the school’s identity and values.

Natural and Artificial Lighting: The amount and quality of natural and artificial lighting in a space can impact how colors are perceived. Architects consider the lighting conditions of each area when selecting colors to ensure they appear as intended. They may choose lighter colors to enhance natural light or incorporate lighting design strategies that complement the chosen color scheme.

We start our exploration of best practice with the International Building Code which defines occupancy classifications and sets standards for architectural coating selection, application and maintenance contribute to safety and sustainability goals.

New Standard Will Aid in Color Calculation of Objects

ASTM Committee E12 on Color and Appearance


According to ASTM member Hugh Fairman, legacy standard E308 gathered data and pre-calculated weight sets for doing what is called “tristimulus integration,” which determines the actual color of a measured spectral reflectance or spectral power curve. While this standard is still useful in certain cases, a need has grown for the more updated practice described in E3415 to respond to interest in how illumination is perceived on painted surfaces.

Standards Michigan: ASTM International
