Water and Electricity

Supporting swimming pools with electricity involves various essential functions such as filtration, heating, lighting, and sanitation. Ensuring safety and energy efficiency is crucial, and pool owners can take steps to minimize electricity costs and environmental impact. Key points:

Filtration and Circulation: Swimming pools rely on electric pumps to circulate water through filters, removing debris and maintaining water quality.

Heating: Electric heaters or heat pumps are used to regulate water temperature for comfort, especially in colder seasons.

Lighting: Underwater and pool area lighting enhance safety and aesthetics, typically powered by electricity.

Chlorination and Sanitation: Electric chlorinators or ozone generators help maintain water cleanliness and hygiene.

Automation: Electric control systems enable pool owners to manage filtration, heating, and lighting remotely for convenience and energy efficiency.

Energy Efficiency: Pool owners can invest in energy-efficient equipment, like variable-speed pumps and LED lighting, to reduce electricity consumption and operating costs.

Operations and Maintenance: Regular electrical maintenance ensures safe and reliable pool operation, preventing electrical faults and hazards.  The electricity cost for pool operation can be significant, so pool owners should consider energy-efficient practices and equipment to reduce expenses.

Education communities present one of the largest installed bases of artificially created bodies of water; the most abundance resource on earth.  These bodies vary in size, purpose, and design but are all created by human intervention to serve specific needs, whether practical, recreational, or aesthetic.  Safe and sustainable management of them in the Unite States are informed by best practice found in Article 680 of the National Electrical Code with scope statement below:

Construction and installation of electrical wiring for, and equipment in or adjacent to, all swimming, wading, therapeutic, and decorative pools; fountains; hot tubs; spas; and hydromassage bathtubs, whether permanently installed or storable, and to metallic auxiliary equipment, such as pumps, filters, and similar equipment.

“No work of art can be great,

if it is not composed of the smallest things.”

Vitruvius  (Book VII, Chapter 9)

 

Today 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.

During today’s session we approach disaster avoidance, management and recovery literature from a different point of view than our customary approach — i.e. what happens when, a) there is failure to conform to the standard, b) there is no applicable standard at all.  This approach necessarily requires venturing into the regulatory and legal domains.  We will confine our approach to the following standards development regimes:

  1. De facto standards: These are standards that are not officially recognized or endorsed by any formal organization or government entity, but have become widely adopted by industry or through market forces. Examples include the QWERTY keyboard layout and the MP3 audio format.
  2. De jure standards: These are standards that are formally recognized and endorsed by a government or standard-setting organization. Examples include the ISO 9000 quality management standard and the IEEE 802.11 wireless networking standard.
  3. Consortium standards: These are standards that are developed and maintained by a group of industry stakeholders or organizations, often with the goal of advancing a particular technology or product. Examples include the USB and Bluetooth standards, which are maintained by the USB Implementers Forum and the Bluetooth Special Interest Group, respectively.
  4. Open standards: These are standards that are freely available and can be used, implemented, and modified by anyone without restriction. Examples include the HTML web markup language and the Linux operating system.
  5. Proprietary standards: These are standards that are owned and controlled by a single organization, and may require payment of licensing fees or other restrictions for use or implementation. Examples include the Microsoft Office document format and the Adobe PDF document format.
  6. ANSI accredited standards developers with disaster management catalogs

We may have time to review State of Emergency laws on the books of most government agencies; with special attention to power blackout disasters.

Smart classroom: Gateway for ubiquitous classroom

Hichem Bargaoui & Rawia Bdiwi

In educational environment, the use of new pedagogies such as collaborative learning requires an evolution from a traditional classroom model to active classroom. The students should be able to share resources to collaborate with each other through computers, tablets, or other devices. The design of smart classroom should enable the control of audiovisual equipments, projectors, interactive whiteboards, in order to facilitate interaction among teachers and students. Ubiquitous computing or pervasive computing is a concept where processors and sensors are embedded in various physical objects to form a network and communicate information. Applying the pervasive computing can facilitate the collaborative learning by creating a smart learning environment. The ubiquitous classroom should be able to support interaction of heterogeneous devices connected through wireless links to a gateway. This paper presents a model of classroom that makes several smart devices such as laptops, tablets, projectors connected through a gateway in order to encourage communication of information between learners and the smart environment. Also, the gateway manages classroom smart devices by automatic detection and connectivity and it serves as application execution platform. Finally the gateway allows the classroom to be remote managed as well as the remote integration of application.
