Abstract:  One of the most common questions in the early stages of designing a new facility is whether the normal utility supply to a fire pump is reliable enough to “tap ahead of the main” or whether the fire pump supply is so unreliable that it must have an emergency power source, typically an on-site generator. Apart from the obligation to meet life safety objectives, it is not uncommon that capital on the order of 100000to1 million is at stake for a fire pump backup source. Until now, that decision has only been answered with intuition – using a combination of utility outage history and anecdotes about what has worked before. There are processes for making the decision about whether a facility needs a second source of power using quantitative analysis. Fault tree analysis and reliability block diagram are two quantitative methods used in reliability engineering for assessing risk. This paper will use a simple one line for the power to a fire pump to show how each of these techniques can be used to calculate the reliability of electric power to a fire pump. This paper will also discuss the strengths and weakness of the two methods. The hope is that these methods will begin tracking in the National Fire Protection Association documents that deal with fire pump power sources and can be used as another tool to inform design engineers and authorities having jurisdiction about public safety and property protection. These methods will enlighten decisions about the relative cost of risk control with quantitative information about the incremental cost of additional 9’s of operational availability.

Design Considerations for Hot Water Plumbing

Baseline Standards for Student Housing

2024/2025/2026 ICC CODE DEVELOPMENT SCHEDULE

Indoor plumbing has a long history, but it became widely available in the 19th and early 20th centuries. In the United States, for example, the first indoor plumbing system was installed in the Governor’s Palace in Williamsburg, Virginia in the early 18th century. However, it was not until the mid-19th century that indoor plumbing became more common in middle-class homes.

One important milestone was the development of cast iron pipes in the 19th century, which made it easier to transport water and waste throughout a building. The introduction of the flush toilet in the mid-19th century also played a significant role in making indoor plumbing more practical and sanitary.

By the early 20th century, indoor plumbing had become a standard feature in most middle-class homes in the United States and other developed countries. However, it was still not widely available in rural areas and poorer urban neighborhoods until much later.

Today we break down public consultation notices for literature that sets the standard of care for the safety and sustainability of student housing in K-12 prep schools, colleges and universities.  We deal with off-campus housing in a separate session because it involves local safety and sustainability regulations; most of which are derived from residential housing codes and standards.

Monograph: The Case for Campus Housing

Off-Campus Housing

The topic cuts across many disciplines and standards setting organization bibliographies. We usually set our bearing with the following titles:

2021 International Building Code: Section 310 Residential Group R-2 + related titles such as the IFC, IMC, IPC, IECC

2021 Fire Code: Chapter 6 Classification of Occupancy  + related titles such as NFPA 70B, NFPA 72 and NFPA 110

2023 National Electrical Code: Articles 210-230 + related Articles 110 and 410

ASHRAE 90.1 Energy Standard for Buildings Except Low-Rise Residential Buildings: Annex G

Like any other classification of real property the average cost for room and board for a public university student dormitory depends on several factors such as the location of the university, the type of dormitory, and the meal plan options.  According to the College Board, the average cost of room and board for the 2021-2022 academic year at a public four-year in-state institution was $11,620. However, this figure can range from around $7,000 to $16,000 or more depending on the specific institution and its location.   It’s important to note that this average cost only includes the basic meal plan and standard dormitory room. Students may also have additional costs for a larger or more luxurious dorm room, a premium meal plan, or other expenses such as laundry or parking fees.   

According to ring Rider Levett Bucknall, a global property and construction consultancy firm, the average construction cost for a student housing facility in the United States in 2021 was around $202 per square foot. However, this figure can range from around $150 to $300 per square foot or more depending on the specific project.  Life cycle cost for new facilities with tricked out net-zero gadgets is hard to come by at the moment.

Because money flows freely through this domain we examine scalable densities and the nature of money flow patterns; partially tracked by the Electronic Municipal Market Access always on the standing agenda of our Finance colloquium.

Here are a few pros and cons of private sector construction of university-owned student housing:

Pros:

  1. Increased housing availability: Private sector developers may be able to build more student housing units than a university could build on its own, which can help to alleviate the shortage of on-campus housing for students.
  2. Faster construction: Private developers may be able to complete construction projects faster than universities, which can help to reduce the amount of time that students must wait for new housing options.
  3. Reduced financial burden on the university: The cost of building and maintaining student housing can be significant, and private sector developers may be willing to bear some of these costs. This can help to reduce the financial burden on the university and free up resources for other initiatives.
  4. Professional management: Private developers may have more experience managing large housing projects and may be able to provide more professional management services than a university could provide on its own.

Cons:

  1. Higher costs for students: Private developers may charge higher rents than a university would charge for student housing, which can make housing less affordable for some students.
  2. Reduced university control: Private developers may have different priorities than a university would have when it comes to building and managing student housing. This can lead to a reduced level of control for the university over housing quality, management, and policies.
  3. Potential conflicts of interest: Private developers may be more focused on making a profit than on meeting the needs of students or the university, which can create potential conflicts of interest.
  4. Less transparency: Private developers may not be subject to the same level of transparency and accountability as a university would be when it comes to housing policies, decision-making processes, and financial management.

It’s important to note that these pros and cons may vary depending on the specific circumstances and context of each individual university and private sector partnership.

Today we amble through the literature providing policy templates informing school district, college and university-affiliated transportation and parking facilities and systems.   Starting 2024 we will break up our coverage thus:

Mobility 100 (Survey of both ground and air transportation instructional and research facilities)

Mobility 200 (Ground Transportation)

Mobility 300 (Air Transportation)

Mobility 400 (Reserved for zoning, parking space allocation and enforcement, and issues related to one of the most troublesome conditions in educational settlements)

Today’s session will be the last when we cover both land and air transportation codes, standards, guidelines and the regulations that depend upon all them. We will break out space and aerospace mobility into a separate session — largely because many universities are tooling up square footage and facilities in anticipation of research grants.

International Code Council

Electric Vehicle Charging

International Electrotechnical Commission

SyC Smart Cities

International Organization for Standardization

Intelligent Transport Systems
Road Vehicles

Institute of Electrical and Electronic Engineers

 Intelligent Transportation Systems Society

Noteworthy:

The public school bus system in the United States is the largest public transit system in the United States. According to the American School Bus Council, approximately 25 million students in the United States ride school buses to and from school each day, which is more than twice the number of passengers that use all other forms of public transportation combined.

The school bus system is considered a public transit system because it is operated by public schools and school districts, and provides a form of transportation that is funded by taxpayers and available to the general public. The school bus system also plays a critical role in ensuring that students have access to education, particularly in rural and low-income areas where transportation options may be limited.

…and 50-state spinoffs of the foregoing.  (See our ABOUT for further discussion of education industry non-profit associations)

There are several ad hoc consortia in this domain also; which include plug-in hybrid electric vehicles.  Charging specifications are at least temporarily “stable”; though who should pay for the charging infrastructure in the long run is a debate we have tracked for several revision cycles in building and fire codes.

Because incumbents are leading the electromobility transformation, and incumbents have deep pockets for market-making despite the “jankiness” of the US power grid, we can track some (not all) legislation action, and prospective public comment opportunities.   For example:

S. 1254: Stop for School Buses Act of 2019

S. 1750 Clean School Bus Grant Program

S. 1939 / Smarter Transportation Act

Keep in mind that even though proposed legislation is sun-setted in a previous (116th) Congress, the concepts may be carried forward into the following Congress (117th).

Public consultations on mobility technologies relevant to the education facility industry are also covered by the IEEE Education & Healthcare Facilities Committee which meets 4 times monthly in European and American time zones.

This topic is growing rapidly and it may well be that we will have to break it up into more manageable pieces.  For the moment, today’s colloquium is open to everyone.  Use the login credentials at the upper right of our home page.

Campus Rail Transit

The West Virginia University PRT (Personal Rapid Transit) system is a unique and innovative form of public transportation that serves the WVU campus and the city of Morgantown, West Virginia. The PRT system consists of a series of automated, driverless vehicles that operate on an elevated track network, providing fast and convenient transportation to key destinations on and around the WVU campus.

The PRT system was first developed in the 1970s as a solution to the growing traffic congestion and parking demand on the WVU campus. The system was designed to be efficient, reliable, and environmentally friendly, and to provide a high-tech, futuristic mode of transportation that would appeal to students and visitors.

The PRT system currently operates five different stations, with stops at key campus locations such as the Mountainlair Student Union, the Engineering Research Building, and the Health Sciences Center. The system is free for all WVU students, faculty, and staff, and also offers a low-cost fare for members of the general public.

The PRT system has been recognized as one of the most advanced and innovative public transportation systems in the world, and has won numerous awards for its design, efficiency, and environmental sustainability. It has also become an iconic symbol of the WVU campus, and is often featured in promotional materials and advertising campaigns for the university.
