Note the following proposed changes in the transcript above: E59-24, F62-24, Section 323
Modular classrooms, often used as temporary or semi-permanent solutions for additional educational space, have specific requirements in various aspects to ensure they are safe, functional, and comfortable for occupants. Today we will examine best practice literature for structural, architectural, fire safety, electrical, HVAC, and lighting requirements. Use the login credentials at the upper right of our home page.
Structural Requirements
Foundation and Stability: Modular classrooms require a stable and level foundation. This can be achieved using piers, slabs, or crawl spaces. The foundation must support the building’s weight and withstand environmental forces like wind and seismic activity.
Frame and Load-Bearing Capacity: The frame, usually made of steel or wood, must support the load of the classroom, including the roof, walls, and occupants. Structural integrity must comply with local building codes.
Durability: Materials used should be durable and capable of withstanding frequent relocations if necessary.
Architectural Requirements
Design and Layout: Modular classrooms should be designed to maximize space efficiency while meeting educational needs. This includes appropriate classroom sizes, storage areas, and accessibility features.
Accessibility: Must comply with the Americans with Disabilities Act (ADA) or other relevant regulations, ensuring accessibility for all students and staff, including ramps, wide doorways, and accessible restrooms.
Insulation and Soundproofing: Adequate insulation for thermal comfort and soundproofing to minimize noise disruption is essential.
Fire Safety Requirements
Fire-Resistant Materials: Use fire-resistant materials for construction, including fire-rated walls, ceilings, and floors.
Sprinkler Systems: Installation of automatic sprinkler systems as per local fire codes.
Smoke Detectors and Alarms: Smoke detectors and fire alarms must be installed and regularly maintained.
Emergency Exits: Clearly marked emergency exits, including doorways and windows, with unobstructed access paths.
Electrical Requirements
Electrical Load Capacity: Sufficient electrical capacity to support lighting, HVAC systems, and educational equipment like computers and projectors.
Wiring Standards: Compliance with National Electrical Code (NEC) or local electrical codes, including proper grounding and circuit protection.
Outlets and Switches: Adequate number of electrical outlets and switches, placed conveniently for classroom use.
HVAC (Heating, Ventilation, and Air Conditioning) Requirements
Heating and Cooling Systems: Properly sized HVAC systems to ensure comfortable temperatures year-round.
Ventilation: Adequate ventilation to provide fresh air and control humidity levels, including exhaust fans in restrooms and possibly kitchens.
Air Quality: Use of air filters and regular maintenance to ensure good indoor air quality.
Lighting Requirements
Natural Light: Maximization of natural light through windows and skylights to create a pleasant learning environment.
Artificial Lighting: Sufficient artificial lighting with a focus on energy efficiency, typically using LED fixtures. Lighting should be evenly distributed and glare-free.
Emergency Lighting: Battery-operated emergency lighting for use during power outages.
By adhering to these requirements, modular classrooms can provide safe, functional, and comfortable educational spaces that meet the needs of students and staff while complying with local regulations and standards.
Today during our usual hour we sweep through standards action in building glazing, entrances and means of egress. The word fenestration (Latin: fenestra) has become a term of art for the design, construction, and placement of openings in a building, including windows, doors, skylights, and other glazed elements. While the word has sparse use in the International Code Council and National Fire Protection Association catalog it is widely used by the Construction Specifications Institute in its MasterFormat system for organizing construction standards, guidelines and building contracts.
The percentage of a building envelope “skin” that is comprised of doors and windows varies depending on the specific building design, function, and location. However, a commonly cited range is between 15% to 25% of the total building envelope. The actual percentage will depend on several factors such as the building’s purpose, orientation, local climate, and energy performance goals. Buildings that require more natural light or ventilation, such as schools, hospitals, and offices, may have a higher percentage of windows and doors in their envelope. In contrast, buildings with lower lighting and ventilation requirements, such as warehouses, may have a smaller percentage of windows and doors.
Fenestration presents elevated risk to facility managers. The education facility industry is a large target and a pattern of settling out of court. For example:
In 2013, a former student at Yale University sued the school over a broken window in her dorm room. The student alleged that the university was negligent in failing to repair the window, which allowed a burglar to enter her room and sexually assault her. The case was settled out of court in 2015 for an undisclosed amount.
In 2019, a student at the University of California, Los Angeles sued the school over a broken window in her apartment. The student alleged that the university was negligent in failing to repair the window, which allowed a swarm of bees to enter her apartment and sting her. The case was settled out of court for $4.5 million.
In 2020, a group of students at Harvard University sued the school over its decision to require them to move out of their dorms due to the COVID-19 pandemic. The students alleged that the university breached its contract with them by failing to provide suitable alternative housing, including functioning windows and doors. (The case is ongoing; best we can tell as of the date of this post).
These cases illustrate that colleges and universities can face legal action related to doors and windows, either due to alleged negligence in maintaining or repairing them, or due to issues related to student housing and accommodations.
Our inquiry breaks down into two modules at the moment:
The latest version of the ICC/MBI Standard 1200 is the 2020 edition, specifically the ICC/MBI 1200-2020: Standard for Off-Site Construction: Planning, Design, Fabrication and Assembly. This standard, developed by the International Code Council (ICC) in collaboration with the Modular Building Institute (MBI), addresses the planning, design, fabrication, and assembly of off-site construction projects. It is part of a series of standards aimed at ensuring safety and compliance in off-site construction processes.
The Life Safety Code addresses those construction, protection, and occupancy features necessary to minimize danger to life from the effects of fire, including smoke, heat, and toxic gases created during a fire. It is widely incorporated by reference into public safety statutes; typically coupled with the consensus products of the International Code Council. It is a mighty document — one of the NFPA’s leading titles — so we deal with it in pieces; consulting it for decisions to be made for the following:
(1) Determination of the occupancy classification in Chapters 12 through 42.
(2) Determination of whether a building or structure is new or existing.
(3) Determination of the occupant load.
(4) Determination of the hazard of contents.
There are emergent issues — such as active shooter response, integration of life and fire safety systems on the internet of small things — and recurrent issues such as excessive rehabilitation and conformity criteria and the ever-expanding requirements for sprinklers and portable fire extinguishers with which to reckon. It is never easy telling a safety professional paid to make a market for his product or service that it is impossible to be alive and safe. It is even harder telling the dean of a department how much it will cost to bring the square-footage under his stewardship up to the current code.
The 2021 edition is the current edition and is accessible below:
Public input on the 2027 Revision will be received until June 4, 2024. Public comment on the Second Draft 2027 Revision will be received until March 31, 2026.
Since the Life Safety Code is one of the most “living” of living documents — the International Building Code and the National Electric Code also move continuously — we can start anywhere and anytime and still make meaningful contributions to it. We have been advocating in this document since the 2003 edition in which we submitted proposals for changes such as:
• A student residence facility life safety crosswalk between NFPA 101 and the International Building Code
• Refinements to Chapters 14 and 15 covering education facilities (with particular attention to door technologies)
• Identification of an ingress path for rescue and recovery personnel toward electric service equipment installations.
• Risk-informed requirement for installation of grab bars in bathing areas
• Modification of the 90-minute emergency lighting requirements rule for small buildings and for fixed interval testing
• Modification of emergency illumination fixed interval testing
• Table 7.3.1 Occupant Load revisions
• Harmonization of egress path width with European building codes
There are others. It is typically difficult to make changes to stabilized standard though some of the concepts were integrated by the committee into other parts of the NFPA 101 in unexpected, though productive, ways. Example transcripts of proposed 2023 revisions to the education facility chapter is linked below:
Since NFPA 101 is so vast in its implications we list a few of the sections we track, and can drill into further, according to client interest:
Chapter 3: Definitions
Chapter 7: Means of Egress
Chapter 12: New Assembly Occupancies
Chapter 13: Existing Assembly Occupancies
Chapter 16 Public Input Report: New Day-Care Facilities
Chapter 17 Public Input Report: Existing Day Care Facilities
Chapter 18 Public Input Report: New Health Care Facilities
Chapter 19 Public Input Report: Existing Health Care Facilities
Chapter 28: Public Input Report: New Hotels and Dormitories
Chapter 29: Public Input Report: Existing Hotels and Dormitories
Chapter 43: Building Rehabilitation
Annex A: Explanatory Material
As always we encourage front-line staff, facility managers, subject matter experts and trade associations to participate directly in the NFPA code development process (CLICK HERE to get started)
NFPA 101 is a cross-cutting title so we maintain it on the agenda of our several colloquia —Housing, Prometheus, Security and Pathways colloquia. See our CALENDAR for the next online meeting; open to everyone.

US Offsite partnered with RSA to design, manufacture, and deliver five new modular buildings that met California’s snow-load standards and doubled classroom capacity — all in under 10 months.
Today we run through recent action in fire safety best practice literature. Even though fire safety technologies comprise about 2-4 percent of a new building budget, the influence of the fire safety culture dominates all aspects campus safety; cybersecurity of public safety communication technology for example.
A small sample of the issues we have tracked in the past: (2002-2023). Items in RED indicate success in reducing cost with no reduction in safety (i.e. successful rebuttal, typically market-making by incumbents)
Limiting vendor lock-in (promote interoperability) in building additions.
Limiting the tendency to lowball first cost in order to achieve vendor lock-in later in the facility life-cycle
Scalability of fire safety professional certification
Sprinklering of off-campus student housing
Advocating central (or campus district) fire pump systems
One of the newer issues to revisit over the past few years is the fire safety of tents. Many colleges and universities are setting up large commercial tents outside buildings (within range of Wi-Fi) for students to congregate, study and dine. We are also seeing back and forth on fire safety in theatrical performance venues in the International Code Council building safety catalog.
We approach these titles with an eye toward driving risk-informed, performance requirements that reduce risk and cost for the user interest; while recognizing the responsibility of competitor stakeholders. It is not a friendly space for the user-interest who seeks to optimally resolve the competing requirements of safety and economy. Vertical incumbents completely dominate this domain.
That’s a wrap on our 2024 open days! Thank you to everyone who came to visit us this year and to all of our wonderful staff and students who supported these events. ✨
